Embodiment

(19) As shown in FIG. 2, the embodiment of the invention provides an LED light source high-beam and low-beam integrated automobile lamp module with an ADB function. The LED light source high-beam and low-beam integrated automobile lamp module with the ADB function is arranged in a headlamp of an automobile to be used for illumination in a high-beam mode, low-beam mode or ADB mode.

(20) As shown in FIG. 1, optical elements of the automobile lamp module include a condenser 1, three high-beam LED light sources 2, a low-beam LED light source 2, a reflector 5 and a lens 6, wherein the condenser 1 is made from a transparent material; the three high-beam LED light sources 2 and the low-beam LED light source 3 are arranged on a rear side, namely an incident light side, of the condenser (1); the reflector 5 is arranged on a front upper portion of the condenser (1); and the lens 6 is arranged on a front side of the condenser (1). The high-beam LED light source at a rear end of a block cavity structure (7) provided with an opening in an upper portion can be independently lit on or lit off.

(21) The condenser (1) is made from PC with a refractivity of about 1.586 and has a light transmittance of about 0.88.

(22) An auxiliary reflector 4 is arranged beside the low-beam LED light source (3).

(23) The block cavity structure (7) provided with the opening in the upper portion is arranged on a left or right portion of the condenser (1).

(24) The block cavity structure is an irregular quasi-quadrangle. An inner rear end face (7-1) and an inner middle end face (7-2) of the block cavity structure are flat faces. The inner rear end face of the block cavity structure is an incident light side. An outer front end face (1-3) of the condenser (1) is a flat face or an arc face. An inner front end face (7-3), namely the end face of the side close to the lens (6), of the block cavity structure is a flat face or an arc face, which is identical with the outer front end face of the condenser (1) and is matched with the outer front end face of the condenser (1).

(25) An acute angle is formed at a joint of the inner rear end face (7-1) and the inner middle end face (7-2) of the block cavity structure on the condenser (1), so that a clear ADB cut-off line is formed.

(26) At the rear end of the condenser (1), the high-beam LED light source corresponding to the block cavity structure (7) arranged on the left or right portion of the condenser (1) and provided with the opening in the upper portion is in a lit-up state when being in a full-high-beam working state, and light emitted thereby is transmitted by the block cavity structure and is then emitted forwards, so as to form a part of a high-beam light shape.

(27) At the rear end of the condenser (1), the high-beam LED light source corresponding to the block cavity structure (7) arranged on the left or right portion of the condenser (1) and provided with the opening in the upper portion is in an off state when being in an ADB state, the other LED light sources are lit up, and light is fully reflected and is then emitted forwards after being irradiated on a side face of the block cavity structure, so as to form an ADB light shape.

(28) As shown in FIGS. 3, 5 and 6, the condenser (1) is applied to a left automobile lamp, and the block cavity structure is arranged on a left side of the condenser corresponding to the left automobile lamp. In this way, when the block cavity structure is located on the left portion of the condenser, light emitted by the right high-beam LED light source is fully reflected on an inner side face, close to the middle of the condenser, of the block cavity structure on the left portion of the condenser.

(29) As shown in FIG. 4, the condenser (1) is applied to a right automobile lamp, and the block cavity structure is arranged on a right side of the condenser corresponding to the right automobile lamp. In this way, when the block cavity structure is arranged on the right portion of the condenser, light emitted by the left high-beam LED light source is fully reflected on an inner side face, close to the middle of the condenser, of the block cavity structure on the right portion of the condenser.

(30) The condenser (1) is applied to a left or right automobile lamp, and when the number of the high-beam LED light sources (2) is an odd number such as 3 or 5, an inner side face, close to the middle of the condenser, of the block cavity structure is at least located on a left or right side of the axis of light emitted by the middle high-beam LED light source.

(31) The distance from the inner front end face (7-3) of the block cavity structure on the left or right portion of the condenser (1) to the outer front end face (1-3) of the condenser is 2-10 mm.

(32) The condenser (1) is made from transparent plastic or silica gel and is preferably made from PC.

(33) The outer front end face of the condenser (1) is a concave arc face.

(34) In addition, in this embodiment, an area III forming structure (1-2) is arranged on an upper portion of the condenser (1). The area III forming structure (1-2) comprises an area III breadth forming structure (1-2-1) and a 50 L dark area forming structure (1-2-3). Light forming an area III is reflected by the reflector and then enters the area III breadth forming structure (1-2-1) after being emitted by the low-beam LED light source.

(35) An area III brightness reduction structure (1-2-2) in the shape of a square slot is formed in a lower edge of one side of the area III breadth forming structure (1-2-1) on the condenser (1) of the high-beam and low-beam integrated automobile lamp module. The brightness of a specific region of the area III can be reduced to 0.1 lx-0.7 lx during light distribution by adjusting the length, width, height and spatial position of the area III brightness reduction structure (1-2-2).

(36) The 50 L dark area forming structure (1-2-3) is arranged in the light transmission direction and is in a convex triangle shape or in other shapes. The brightness of a 50 L area in a low-beam light shape can be controlled below a certain value by the 50 L dark area forming structure.

(37) An end face of the area III breadth forming structure (1-2-1) is in a concave arc shape or in a convex arc shape.

(38) In addition, an area III brightness reduction structure (1-2-2) in the shape of a rectangular slot is formed in a lower edge of one side of the area III breadth forming structure (1-2-1). The brightness of a local part of an area III in a low-beam light shape can be reduced by the area III brightness reduction structure (1-2-2), so that dazzling is prevented while sufficient illumination is provided by a low beam.

(39) The area III brightness reduction structure specifically has a length of about 2.8 mm, a width of about 0.4 mm and a height of about 0.3 mm and is used for reducing the brightness of a local part of an area III in the low-beam light shape.

(40) The condenser is used to light up a left or right automobile lamp and thus is generally installed on the automobile lamp in use.

(41) As shown in FIG. 3, the condenser (1) is located in the left automobile lamp, and the block cavity structure is located on a left side of the emergent light direction under the top view of the module, wherein the emergent light direction refers to the direction from the second high-beam LED light source to the lens 6.

(42) As shown in FIG. 4, the condenser 1 is located in the right automobile lamp, and the block cavity structure is arranged on a right side of the emergent light direction under the top view of the module.

(43) As shown in FIG. 5, the LED light source (2-1) corresponding to the rear end of the block cavity structure on the condenser (1) is in a lit-up state when being in a full-high-beam working state, and light emitted thereby is transmitted by the block cavity structure and is then emitted forwards so as to form a part of a high-beam light shape and is combined with light emitted by the other two LED light sources (2-2) and (2-3) to form full-high-beam light. The light shape of the full-high-beam light is shown in FIG. 7, and the corresponding pavement effect picture is shown in FIG. 11. In this case, the pavement is completely illuminated, and good visibility is realized.

(44) As shown in FIG. 6, the LED light source corresponding to the rear end of the block cavity structure on the condenser (1) is in an off state when being in an ADB working state, the other two LED light sources are lit up, and light is fully reflected and is then emitted forwards after being irradiated on a side face of the block cavity structure, so as to form an ADB light shape. The ADB light shape of the left automobile lamp is shown in FIG. 8, the ADB light shape of the right automobile lamp is shown in FIG. 9, and the overlapped light shape of the left automobile lamp and the right automobile lamp in the ADB working state is shown in FIG. 10, wherein a concave area in the middle is a dark area formed for protecting a vehicle from the opposite direction against dazzling, and the size of the dark area can be adjusted by rotating the module in the left or right automobile lamp leftwards or rightwards so as to adapt to different illumination ranges. The pavement effect picture in the ADB working state is shown in FIG. 12. As shown in FIG. 12, the automobile has a good illumination effect when running on a two-way lane, and the driver of an automobile from the opposite direction is protected against dazzling, so that the driving safety is improved.
