DETAILED DESCRIPTION OF THE INVENTION

[0052] One exemplary embodiment of the present disclosure will be discussed next with reference to the accompanying Drawings, in which like reference numbers are used to indicate like elements. In the following discussion, many details are explained to provide a better and more comprehensive understanding of the present application. Nevertheless, it should be appreciated that the present application may be embodied without these details, and is not limited to the exemplary embodiments disclosed in the present application.

[0053] As shown in FIGS. 1 to 3, the present application provides a projector lamp 100 comprising a hollow lamp housing 12, wherein the lamp housing 12 has an opening 120 formed at the first end thereof. A power supply adaptor 11 is mounted inside said lamp housing 12, and is communicated with an external power supply via the second end of said lamp housing 12. A lighting module 6 is mounted inside said lamp housing 12, and has: a circuit board 61 electrically connected with the power supply adaptor 11; and a plurality of light emitting diode units 62, which are electrically mounted on said circuit board 61, so as to emit light when said projector lamp 100 is energized. A lens 1 is mounted at the opening 120 of the lamp housing 12, such that the light emitted by the plurality of light emitting diode units 62 projects out therethrough.

[0054] The projector lamp 100 further comprises an adjusting assembly 9, which comprises: an adjusting ring 91, an operator being able to operate said adjusting ring 91 external of said lamp housing 12 to rotate it around a longitudinal axis of the lamp housing 12 extending from the first end to the second end. The adjusting assembly 9 further comprises a controller 93, which is electrically connected with the lighting module 6 and is coupled to the adjusting ring 91, such that when the adjusting ring 91 is rotated, the controller 93 adjusts the lighting mode of the plurality of light emitting diode units 62 in response to the rotation of the adjusting ring 91.

[0055] In an embodiment, the adjusting ring 91 is mounted on the outer periphery of the lamp housing 12 around an imaginary longitudinal axis of the lamp housing 12 extending from the first end to the second end of said lamp housing 12.

[0056] In an embodiment, a controller 93 is mounted inside the lamp housing 12.

[0057] In a preferred embodiment, the adjusting assembly 9 further comprises an adjusting actuator, which mechanically actuates the adjusting motion of the controller 93 in response to the rotation of the adjusting ring 91. The adjusting actuator may be in the form of an adjusting lever 92. The adjusting lever 92 is disposed between the adjusting ring 91 and the controller 93, and is engaged with them; the rotation of the adjusting ring 91 induces a motion of the adjusting lever 92, such that a controlling switch 931 disposed on the controller 93 is actuated, making the controller 93 in turn adjust the lighting mode of the plurality of light emitting diode units 62. In an embodiment, the controlling switch 931 may be secured by a controlling switch fastener 9311, which may be, for example, connected to the inner wall of the lamp housing 12, or formed integrally with the internal of the lamp housing 12. Specifically, by rotating the adjusting ring 91, various characteristics of the projector lamp 100 can be adjusted, such as lightness, light color etc. Such an adjustment can be either continuous or intermittent.

[0058] FIGS. 4 and 5 illustrate the configuration of the adjusting assembly 9 more clearly.

[0059] In a preferred embodiment, the adjusting ring 91 is rotatable around the longitudinal axis in two directions. With such bidirectional rotations, the lighting mode of the projector lamp 100 can be adjusted reversibly.

[0060] The adjusting lever 92 may comprises a first side leg 921, a second side leg 922 and an intermediate leg 923, wherein the first side leg 921 and the second side leg 922 may be symmetrical with respect to the intermediate leg 923, and the adjusting lever 92 is pivotably mounted on the inner wall of the lamp housing 12 between the first side leg 921 and second side leg 922, at a first end 9231 of the intermediate leg 923, such that it can pivot around an adjusting pivot 121 parallel to the longitudinal axis of the lamp housing; wherein the first side leg 921 and second side leg 922 are engaged with a first controlling switch 931a and a second controlling switch 931b in the controlling switch, respectively; the second end 9232 of the intermediate leg 923 protrudes out through a slot 15 formed in the wall of the lamp housing to engage the adjusting ring 91. The rotation of the adjusting ring 91 may actuate the second end of the intermediate leg 923, making the adjusting lever 92 pivot around the adjusting pivot 121, such that the first side leg 921 or second side leg 922 will actuate the first controlling switch 931a or second controlling switch 931b of the controller 93.

[0061] In an embodiment, the adjusting ring 91 may comprise a plurality of protrusions 911 disposed on the internal periphery thereof and spaced apart from each other. When the adjusting ring 91 is rotated, the plurality of protrusions 911 will contact the second end 9232 of the intermediate leg 923 sequentially, urging the adjusting lever 92 to pivot.

[0062] With the abovementioned configuration of the adjusting ring 91 and adjusting lever 92, the adjusting lever 92 can be mechanically actuated by the rotation of the adjusting ring 91, and said adjusting lever 92 may in turn mechanically actuate respective controlling switch 931a, 931b on the controller 93, making the controller adjust the light emitting diode units 62.

[0063] In an embodiment, adjusting ring 91 is disposed in a recess 14 formed on the outer periphery of the lamp housing 12, such that the outer periphery of the adjusting ring 91 and the outer periphery of the lamp housing 12 form a substantially continuous smooth outer surface, achieving a substantially smooth and streamlined outer profile of the lamp housing.

[0064] The outer periphery of the adjusting ring 91 may also be provided with surface features 912 for the ease of grasping.

[0065] In an embodiment, the adjusting ring 91 is mounted between the opening 120 of the lamp housing and the lens 1.

[0066] A metallic Screw-type lamp base 13 may be sealingly mounted at the second end of the lamp housing 12. Such a metallic Screw-type lamp base 13 is configured such that the projector lamp 100 is applicable in any suitable interfaces.

[0067] The projector lamp 100 may also comprise a water tight seal disposed between the adjusting assembly 9 and the lamp housing 12, and/or a water tight seal disposed between the lens 1 and the opening 120 of the lamp housing 12. With properly mounted seals, the projector lamp 100 can be water proof, and thus may be applicable outdoors, or even under water.

[0068] A motor 7 is mounted within the internal space of the lamp housing 12, which is electrically connected with the power supply adaptor 11, and has a motor shaft 71 facing the opening 120 of the lamp housing 12. A lighting module 6 is mounted in the internal space of the lamp housing 12, in front of the motor 7 (that is, in a direction facing the opening 120 of the lamp housing 12, and around the motor shaft 71. The circuit board 61 is electrically connected with the power supply adaptor 11, and has an orifice 611 formed through the circuit board 61. The circuit board 61 is mounted around the motor shaft 71 by means of the circuit board orifice 611 without contacting the motor shaft 71. The light emitting diode units 62 can emit light beams in different colors, and are electrically mounted on a side of the circuit board 61 distal from the motor 7, or the side opposite the motor 7. The circuit board 61 can control the lighting mode of the light emitting diode units 62, such as flickering mode or normal lighting mode. The power supply adaptor 11 supplies power to the lighting module 6 and the motor 7.

[0069] In an embodiment, an insulating panel may be mounted between the lighting module 6 and the motor 7, so as to keep the motor 7 from being affected by high temperatures generated by the light emitting diode units 62 in operation. The insulating panel may be fixed in the lamp housing 12 on a side of the circuit board 61 facing the motor 7, or on a side of the motor 7 facing the circuit board 61. The insulating panel has an panel orifice formed therethrough. The insulating panel is mounted around the motor shaft through said panel orifice, and is fixed on a side of the circuit board 61 facing the motor 7.

[0070] A multi-surface refractive lens 5 is rotatably mounted in the internal space of the lamp housing 12 and around the motor shaft 71, and is secured to the motor shaft 71. The multi-surface refractive lens 5 is located in front of the lighting module 6. The multi-surface refractive lens 5 has a plurality of multi-angle refractive convex-lenses 51, which are formed in a front side of the multi-surface refractive lens 5 distal from the lighting module 6. The multi-surface refractive lens 5 can be driven by the motor shaft 71 of the motor 7 to be rotated.

[0071] In an embodiment, the lens 1 of the projector lamp 100 is a beam-splitter lens, that is, a beam-splitter lens 1 is mounted at the opening 120 of the lamp housing 12. The beam-splitter lens 1 can be engaged with the lamp housing 12, such as being bonded to the lamp housing 12, or assembled with the lamp housing 12 via threads. The beam-splitter lens 1 can be planar, semispheric, or in other suitable shapes. In case beam-splitter lens 1 is semispheric, it has a plurality of multi-angle refractive convex-lens 111, which are formed on the back side of the semispheric beam-splitter lens 1 facing the multi-surface refractive lens 5.

[0072] A water tight gasket 2 can be mounted between the beam-splitter lens 1 and the opening 120 of the lamp housing 12, to prevent water or moisture from entering into the inner space of the lamp housing 12.

[0073] In operation, the projector lamp 100 is interfaced with any suitable external power supply interface via a metallic threaded lamp base 13. The power supply adaptor 11 can convert alternating current from the external power supply into direct current, to supply power to the motor 7 and the lighting module 6. The light emitting diode units 62 can emit beams of different colors which pass through the multi-angle refractive convex-lenses 51 of the multi-surface refractive lens 5. Meanwhile, the motor shaft 71 of the motor 7 drives the multi-surface refractive lens 5 to rotate. When light is projected through the multi-surface refractive lens 5, the light will be further refracted and further mixed to form light beams of different colors.

[0074] Light beams (homogeneous light or polychromatic light) further pass through the multi-angle refractive convex-lenses 111 of the beam-splitter lens 1, and are further refracted outward through the beam-splitter lens 1. Light beams refracted via the beam-splitter lens 1 can project out in various angles to cover a larger area. Meanwhile, by means of the rotating multi-surface refractive lens 5 and the light emitting diode units 62 flickering in light beams of different colors, the projector lamp can produce various excellent lighting effects resembling kaleidoscope, starry night, icing-cloud, firing-cloud and so forth.

[0075] In one embodiment, the lighting module 6 has a memory function, such that when the projector lamp 100 is reenergized after a power interruption, the light emitted through said opening 120 is identical with that before the power interruption.

[0076] In one embodiment, the adjusting assembly 9 can alternatively be located remote from the hollow lamp housing 12. For example, the adjusting ring 91 is not disposed on the lamp housing, but on a wall or a console remote from the lamp housing 12 and easy to operate. In this case, the lighting mode of the projector lamp 100 can be adjusted by adjusting the adjusting ring 91 at an appropriate position remote from the projector lamp 100.

[0077] The projector lamp can further be applied independently or in combination for many extension indoor or outdoor products. For example the projector lamp can be independently used as a stage lamp, or applied as street lamps, or in inflatable costumes, be applied for forming a dynamic cloud effect, or be embedded inside various cartoon characters or any other suitable objects to realize various shining effects. For example, the projector lamp can be mounted inside a lamp enclosure with translucency or semi-translucency yielding outwardly projects patterns or rear projected patterns upon the enclosure. The projector lamp can be mounted inside inflatable costumes of different shapes or other objects.

[0078] With such a projector lamp, LED light beams of different colors can be refracted by multiple lens and multiple refracting surfaces to form colorful light. The combined lights will produce converging light of various angles to project out from the lens, by means of the integral beam-splitter lens formed by multi-angle refractive convex-lenses, such as forming lighting effects resembling colorful clouds. Rotating the lenses will further produce dynamic colorful cloud effect. Beam-splitter lenses of different shapes and different positions and LEDs of different colors will produce different lighting effects.

[0079] Though the present disclosure has been illustrated and discussed with the exemplary embodiments which are deemed the most practical ones, the inventions of the present application can be embodied in other suitable forms. The embodiments of the present application are thus exemplary, but not limiting in any manner. The scope of the present application is indicated by the appended claims, rather than the previous description, and all the changes or equivalences falling within the scope of their meanings and ranges are all deemed within the protection scopes.
