In some embodiments, the arrangements of the first light emitting diode chip 211 and the second light emitting diode chip 212 are the same in the light emitting diode module 21, that is, the arrangements of the two light emitting diode chips in each light emitting diode module 21 are the same.

[0036] In some other embodiments, the light emitting diode module 21 may include a first light emitting diode chip 211 and a second light emitting diode chip 212 that emit light with two different colors. The first light emitting diode chip 211 is a light emitting chip that emits a light beam of a first color, and the second light emitting diode chip 212 is a light emitting chip that emits a light beam of a second color.

It is understandable that in other embodiments, the first color and the second color may be both red light with different dominant wavelengths, or the first color and the second color may be both green light or blue light with different dominant wavelengths.

[0037] In some other embodiments, the light emitting diode module 21 may include a first light emitting diode chip 211 and a second light emitting diode chip 212 that emit light with different brightness. The first light emitting diode chip 211 is a light emitting chip that emits light with a first brightness, and the second light emitting diode chip 212 is a light emitting chip that emits light with a second brightness. The first brightness may be a high brightness, and the second brightness may be a low brightness. It is understandable that in some other embodiments, the first brightness and the second brightness may be both high brightness or both low brightness.

[0039] In some other embodiments, the light emitting diode module 21 may include light emitting diode chips that emit three different color temperatures. As shown in FIG. 5, the light emitting diode module 21 includes a third light emitting diode chip 213 configured to emit light of a third color temperature, the third color temperature may be between the first color temperature and the second color temperature. It is understandable that the third light emitting diode chip 213 may emit light of a third brightness, a third color or a third color rendering index, the third brightness may be between the first brightness and the second brightness, the third color wavelength may be between the first color wavelength and the second color wavelength, and the third color rendering index may be between the first color rendering index and the second color rendering index.

[0040] In some embodiments, referring to FIG. 4, taking the light emitting diode module 21 including light emitting diode chips emitting light with two different color temperatures as an example, in this case, the first light emitting diode chip 211 and the second light emitting diode chip 212 are configured as one package module and share one collimating lens unit 301. The problem of the solution may be that the main optical axis of the exiting light of the first light emitting diode chip 211 or the second light emitting diode chip 212 does not overlap with the central axis of the collimating lens unit 301, so that a larger part of the light emitted by the first light emitting diode chip and the second light emitting diode chip is not collected by the collimating lens unit and is then wasted, resulting in low light efficiency of the entire light source system.

[0041] The present disclosure provides a light source system, the light source system includes an adjusting mechanism 60. The adjusting mechanism 60 is configured for adjusting the relationship between a collimating lens unit 301 and a light emitting diode chip, so that the main optical axis of the exiting light of a first light emitting diode chip or a second light emitting diode chip included in a light emitting diode module 21 overlaps with the central axis of the collimating lens unit in different dimming modes.

[0042] Referring to FIG. 6, FIG. 6 is a schematic diagram of the light source system in the first mode. In this situation, the main optical axis of the exiting light of the first light emitting diode chip overlaps with the central axis of the collimating lens unit 301 through adjustment of the adjusting mechanism 60, the collimating lens unit 301 may maximize the collection of the light emitted by the first light emitting diode chip. In the meantime, the main optical axis of the exiting light of the second light emitting diode chip deviates greatly from the central axis of the collimating lens unit 301, and the collimating lens unit 301 is difficult to collect the light emitted by the second light emitting diode chip. Therefore, in the first mode, the second light emitting diode chip 212 may be turned off. In conclusion, in the first mode, the main optical axis of the exiting light of the first light emitting diode chip 211 overlaps with the central axis of the collimating lens unit 301, the collimating lens unit may maximize the collection of the exiting light of the first light emitting diode chip, and the first light emitting diode chip may emit light with the first color temperature, so that the light source system emits the illumination light with the first color temperature, which improve the light efficiency of the light source system, and realize the color temperature switching of the light source system, and thereby achieving energy conservation and environmental protection. It should be noted that FIG. 6 schematically illustrates a single first light emitting diode chip and a collimating lens unit as an example, and for other first light emitting diode chips of the light source system, the optical schematic diagram thereof in the first mode is the same as that of FIG. 6, which is not repeated herein. In addition, it should be noted that the main optical axis of the exiting light of the first light emitting diode chip 211 overlaps with the central axis of the collimating lens unit 301, and the present disclosure does not limit that the main optical axis of the exiting light completely overlaps with the central axis, and situations such as substantial overlapping or overlapping within a threshold range also fall in the protection scope of the present disclosure.

[0043] Referring to FIG. 7, FIG. 7 is a schematic diagram of the light source system in the second mode. In this situation, the main optical axis of the exiting light of the second light emitting diode chip overlaps with the central axis of the collimating lens unit 301 through adjustment of the adjusting mechanism 60, the collimating lens unit 301 may maximize the collection of the light emitted by the second light emitting diode chip. In the meantime, the main optical axis of the exiting light of the first light emitting diode chip deviates greatly from the central axis of the collimating lens unit 301, and the collimating lens unit 301 is difficult to collect the light emitted by the first light emitting diode chip. Therefore, in the second mode, the first light emitting diode chip 212 may be turned off. In conclusion, in the second mode, the main optical axis of the exiting light of the second light emitting diode chip 211 overlaps with the central axis of the collimating lens unit 301, the collimating lens unit may maximize the collection of the exiting light of the second light emitting diode chip, and the second light emitting diode chip emit light with the second color temperature, so that the light source system emits the illumination light with the second color temperature, which improve the light efficiency of the light source system, and realize the color temperature switching of the light source system, and thereby achieving energy conservation and environmental protection. It should be noted that FIG. 7 schematically illustrates a single second light emitting diode chip and a collimating lens unit as an example, and for other second light emitting diode chips of the light source system, the optical schematic diagram thereof in the second mode is the same as that of FIG. 7, which is not repeated herein. In addition, it should be noted that the main optical axis of the exiting light of the second light emitting diode chip 212 overlaps with the central axis of the collimating lens unit 301, and the present disclosure does not limit that the main optical axis of the exiting light completely overlaps with the central axis, and situations such as substantial overlapping or overlapping in a threshold range also fall in the protection scope of the present disclosure.

[0044] By adjusting the positional relationship between the light emitting diode module and the collimating lens unit, the light source system is switched between the first mode and the second mode, the illumination light with the first color temperature is emitted in the first mode, and the illumination light with the second color temperature is emitted in the second mode, thereby expanding the application scenario of the light source system and the light efficiency of the light source system. It is understandable that, for a scheme in which the light emitting diode module includes different colors, brightness, or color rendering indexes, the light source system may emit illumination light having a first color, first brightness, or first color rendering index in the first mode, and emit illumination light having a second color, second brightness, or second color rendering index in the second mode.

[0045] In some embodiments, for how to adjust the position between the light emitting diode module and the collimating lens unit, the present disclosure provides an alignment between the light emitting diode module and the collimating lens unit by adjusting the displacement of the collimating lens group 30.

[0046] In some embodiments, referring to FIG. 8 to FIG. 12, the system includes a collimating lens group 30 and an adjusting mechanism 60 for adjusting the collimating lens group 30.

The lens support 31 includes a first mounting portion 3131, a second mounting portion 3132, a first mounting member 3133, and a second mounting member 3134 located on the support plate. The first mounting portion 3131, the second mounting portion 3132, the first mounting member 3133, and the second mounting member 3134 are extensions from an outer edge of the support plate 311. The end portions of the first mounting portion 3131 and the second mounting portion 3132 are provided as protruding columns. The first mounting member 3133 and the second mounting member 3134 respectively include a first sleeve member and a second sleeve member, and the first mounting member 3133 and the second mounting member 3134 are respectively mounted and fixed through the first sleeve member and the second sleeve member. In some embodiments, the lens support 31 includes a bearing mounting hole 3135.

[0047] The adjusting mechanism 60 includes a mounting support 601, the mounting support 601 includes an assembly area located at an edge of the mounting support 601 and an accommodation area 604 located at a center of the mounting support 601. The accommodation area 604 is configured for accommodating a support plate 311 of the collimating lens group 30, and the adjusting mechanism 60 includes a first mounting groove 6021, a second mounting groove 6022, a first mounting composite groove 6023, a second mounting composite groove 6024 and a first mounting platform 6025 located in the assembly area of the mounting support 601. Referring to FIG. 10 and FIG. 11, the adjusting mechanism 60 includes a first limiting module and a second limiting module 603, the first limiting module includes a first limiting plate and a first spring. The first limiting plate is fixed to an opening part of the first mounting groove 6021 by through locking screw, a first limiting column is provided on a side of the first limiting plate facing the mounting groove. When the lens support 31 is assembled with the adjusting mechanism 60, the first mounting portion 3131 of the lens support 31 is accommodated in the first mounting groove 6021, the second mounting portion 3132 is accommodated in the second mounting groove 6022. The first spring is provided in the first mounting groove 6021, one end of the first spring is sleeved on a protruding column at an end portion of the first mounting portion 3131 of the lens support, and the other end of the first spring is sleeved on the first limiting column on the side of the first limiting plate. The second limiting module includes a second limiting plate and a second spring, and the second spring is provided in the second mounting groove 6022. One end of the second spring is sleeved on a protruding column at an end portion of the second mounting portion 3132 of the lens support, and the other end of the second spring is sleeved on the second limiting column on the side of the second limiting plate. The spring provides an elastic force for the lens support to the accommodation area.

[0048] The adjusting mechanism 60 includes a first screw 6041 and a second screw 6042, when the lens support 31 is assembled with the adjusting mechanism 60, the first sleeve member and the second sleeve member included in the first mounting member 3133 of the lens support 31 are sleeved on the first screw 6041. Meanwhile, two ends of the first screw 6041 are arranged in the first mounting composite groove 6023 of the mounting support 601 through pressing the two ends of the first screw 6041 in the first mounting composite groove 6023 by means of screw locking pressure plates. The first sleeve member and the second sleeve member included in the second mounting member 3134 of the lens support 31 are sleeved on the second screw 6042. Meanwhile, two ends of the second screw 6042 are arranged in the second mounting composite groove 6024 of the mounting support 601 through pressing the two ends of the second screw 6042 in the second mounting composite groove 6024 by means of screw locking plates. After assembling, the lens support 31 is mounted on the adjusting mechanism 60, since the mounting member of the lens support is sleeved on the screw, the lens support may only move along the central axis direction of the screw.

[0049] The adjusting mechanism includes a bearing 605, the bearing 605 is locked in the bearing mounting hole 3135 of the lens support 31 through a screw. The aperture of the bearing is larger than the diameter of the screw and smaller than the diameter of the nut, so that the bearing may rotate around the screw.

[0050] The adjusting mechanism 60 includes a first mounting platform 6025 and a slide rail provided on the first mounting platform 6025. The adjusting mechanism further includes an adjusting block 606, a side of the adjusting block 606 facing the first mounting platform 6025 is provided with a slide groove, and the adjusting block 606 is assembled on the first mounting platform 6025 by clamping the slide groove with the slide rail, so that the adjusting block 606 moves on the first mounting platform 6025 through the slide rail. In some embodiments, the adjusting block includes an abutting surface arranged facing the bearing 605, and the abutting surface includes a first step 6061, a second step 6062, and a third step 6063 having a height difference therebetween. In a working state, one of the first step 6061, the second step 6062, and the third step 6063 abuts against the bearing 605. It should be noted that the step is pressed on the bearing, and the bearing rolls between different steps of the adjusting surface. When rolling between different step surfaces, the step squeezes the lens support to move in a direction perpendicular to the step surface.

[0051] The adjusting mechanism includes an adjusting screw 607 and a sleeve 608, the sleeve 608 is fixed to the mounting surface 6064 of the adjusting block 606 by screws. It is understandable that in some other embodiments, the sleeve 608 may also be fixed to the mounting surface 6064 of the adjusting block 606 by welding. In some embodiments, the inner wall of the sleeve 608 is provided with a threaded structure, the outer side wall of the adjusting screw is provided with a threads structure, the sleeve 608 is sleeved on the adjusting screw, and the sleeve 608 is in threaded connection with one end of the adjusting screw 607.

[0052] In some embodiments, the adjusting mechanism includes a screw fixing base 609, the screw fixing base 609 is of a plate-shaped structure, the plate-shaped structure is vertically fixed to the first mounting platform 6025 of the adjusting mechanism 60. The screw fixing base is provided with a screw through hole, the other end of the adjusting screw 607 penetrates through the screw fixing base 609 and is slidably arranged on the screw fixing base 609. It should be noted that, the end portion of the adjusting screw 607 is provided with a rotating wheel, and the adjusting screw may be driven to rotate by twisting the rotating wheel. Rotating the adjusting screw 607 may drive the adjusting block 606 to move along the direction of the central axis of the screw, since the adjusting block 604 is provided with three steps abutting against the bearing 605, during the process that the adjusting block 606 moves along the central axis of the screw, different steps abut against the bearing 605. Different steps abutting against the bearing 605 may generate different movements along the direction perpendicular to the plane of the steps, and since the bearing 605 is arranged on the lens support, the bearing 605 drives the lens support to move along the direction perpendicular to the plane of the steps.

[0053] It should be noted that, in some other embodiments, as shown in FIG. 13, one end of the adjusting screw 607 is connected to the motor 70, and the motor 70 is turned on to drive the adjusting screw 607 to rotate to drive the adjusting block 606 to move.

[0054] It should be noted that the bearing may roll on the first step or the second step surface, the bearing does not move along the length direction of the mounting groove when rolling against the first step, and the bearing moves along the direction perpendicular to the plane of the step only when rolling from the first step to the second step.

[0055] In the specific adjusting process of the collimating lens group 30, firstly, the adjusting screw 607 is driven to rotate, the adjusting screw 607 rotates to drive the adjusting block 606 to move in the direction of the central axis of the screw, and different step surfaces abut against the bearing 605 during the movement of the adjusting block 606. When the first step 6061 abuts against the bearing, under the action force of the spring on the other side of the lens support 31, the collimating lens group 30 and the light source mechanism 20 are at the first relative position. In this position, the first light emitting diode chip 211 included in the light source mechanism 20 is aligned with the collimating lens unit 301, and the light source system is in the first mode. During the movement of the adjusting block 606, the second step 6062 abuts against the bearing 605, and since the height of the second step 6062 is higher than that of the first step 6061, the bearing 605 moves along the direction perpendicular to the plane of the step under the force of the spring on the other side of the lens support 31 and abuts against the second step 6062. In this position, the second light emitting diode chip 212 included in the light source mechanism 20 is aligned with the collimating lens unit 301, and the light source system is in the second mode. It is understandable that, the light source mechanism 20 in the embodiments includes two light emitting chips with different properties, and this may also be applied to the light source mechanism 20 including three light emitting chips with different properties. That is, in the third mode, the third step 6063 of the adjusting block 606 abuts against the bearing 605, and the third light emitting diode chip included in the light source mechanism 20 is aligned with the collimating lens unit 301.

[0056] Referring to FIG. 14, the present disclosure provides a light emitting device 500, and the light emitting device 500 includes the light source system according to any one of the foregoing embodiments. The light emitting device 500 can be a spotlight, a reflector light, a cinema projector, an engineering projector, a micro projector, an education projector, a wall-mounted projector, a laser TV, and so on. The light emitting device 500 includes a housing 501, and the light source system 500 is disposed in the housing 501, and the housing 501 can protect the light source system 500 and prevent the light source system 500 from being directly impacted by the external environment.

[0057] The various embodiments in the present specification are described in a progressive manner, and each embodiment focuses on differences from other embodiments, and the same and similar parts between the various embodiments may be referred to each other.

[0058] The description merely includes some embodiments of the present disclosure, and is not intended to limit the patent scope of the present disclosure, and any equivalent structure or equivalent process transformation made by using the specification and accompanying drawings of the present disclosure, or other directly or indirectly applications related technical fields, which are included in the patent protection scope of the present disclosure.
