Detailed Description
The invention is further described below with reference to the drawings and detailed description.
Referring to fig. 3-7, a structure of a motorcycle taillight includes: the lamp comprises a mounting seat 1, a lamp shade 2 and a light source assembly 3; the mounting seat 1 and the lampshade 2 are spliced to form an accommodating space for accommodating the light source assembly 3;
The light source assembly 3 comprises a lens 31, a light source plate 32, a waterproof sealing layer 33 and a wiring lamp cap 34; an LED patch light source 321 is attached to a surface of the light source plate 32 facing the lampshade 2, and the LED patch light source 321 is divided into a first area 322 and a second area 323 on the light source plate 32; the first area 322 is circular and is located inside the second area 323, and the second area 323 is distributed in a ring shape with the center of the first area 322 as the center; and an annular blank area 324 is formed between the first area 322 and the second area 323;
The lens 31 is coaxially disposed with the light source plate 32, and the position corresponding to the first area 322 is a first light emitting area, the position corresponding to the second area 323 is a second light emitting area, and the first light emitting area and the second light emitting area have different radii of curvature on the surface facing the lampshade 2; the purpose of this is to make the light emitting angles in the first light emitting area and the second light emitting area different, so that the first light emitting area and the second light emitting area have different light effects, and different effects are achieved, which will be described in detail later.
The side of the lens 31 facing the light source plate 32 is provided with a mounting cavity for accommodating the light source plate 32; the side of the light source plate 32 facing away from the lampshade 2 is provided with a circuit structure and is coated with sealant to form a waterproof sealing layer 33;
since the circuit structure needs to be electrically connected to the junction head 34, the waterproof seal 33 is insulated. Therefore, in the production process, after the positive and negative wires of the wiring lamp cap 34 are electrically connected with the positive and negative poles of the circuit structure, the sealant is coated on the surface of the light source plate 32 facing away from the lampshade 2.
Therefore, the primary structure of the whole lamp is formed, and compared with the traditional plug-in type LED patch light source 321, the LED patch light source has the advantages that the production process is greatly simplified, the cost of the motorcycle tail lamp is lower, the light efficiency is higher, the power of the LED patch light source 321 is higher than that of the plug-in type LED patch light source, and therefore the brightness and the effect of the whole lamp after being lighted are better.
In order to solve other problems in the prior art, for example, in a conventional taillight, although two light emitting areas are also divided, light rays in the two light emitting areas are mutually mixed, which is also called channeling light. Specifically, for example, when the first light-emitting region is lit alone, light is refracted to the second light-emitting region and then emitted again from the second light-emitting region, and the whole light-emitting surface emits light except the first light-emitting region when visually seen, and the second light-emitting region emits light, that is, the channeling light.
To solve this problem, in the present embodiment, on a surface of the lens 31 facing the light source plate 32, a first total reflection surface 311 and a second total reflection surface 312 are provided along a direction in which the blank area 324 extends at positions corresponding to the blank area 324; light emitted by the LED patch light source 321 in the first area 322 is reflected by the first total reflection surface 311 and then emitted from the first light emitting area; light emitted by the LED patch light source 321 in the second area 323 is reflected by the second total reflection surface 312 and then emitted from the second light emitting area; so that the light rays in the first and second regions 322 and 323 do not cross each other. The problem of light channeling is perfectly solved.
The above describes that the brightness and the angle of the light emergent light of the first light emergent area and the second light emergent area are different, so that the lights with different functions are realized. Specifically, in this embodiment, the LED patch light source 321 is an SMD LED light source; and the color of the light emitted from the LED patch light source 321 in the first region 322 is the same as or different from the color of the light emitted from the LED patch light source 321 in the second region 323.
In order to provide different light-emitting effects for the tail light, the circuit structure controls the LED patch light sources 321 in the first area 322 and the second area 323 to be individually or simultaneously lighted.
When the color of the light emitted from the LED patch light source 321 in the first area 322 is the same as the color of the light emitted from the LED patch light source 321 in the second area 323, the color of the light emitted from the LED patch light source 321 in the first area 322 and the second area 323 is red. At this time, when the LED patch light source 321 in the second region 323 is individually lighted, the tail lamp functions as a rear lamp. And when the LED patch light sources 321 in the first area 322 and the second area 323 are all lighted, the tail lamp plays a role of a brake lamp.
When the color of the light emitted from the LED patch light source 321 in the first area 322 is different from the color of the light emitted from the LED patch light source 321 in the second area 323, the color of the light emitted from the LED patch light source 321 in the first area 322 is yellow, and the color of the light emitted from the LED patch light source 321 in the second area 323 is white; at this time, the LED patch light source 321 in the second region 323 is individually lighted, and the tail lamp functions as a daytime running light, whereas the LED patch light source 321 in the first region 322 is individually lighted, and the tail lamp functions as a turn signal.
In order to realize that the light-emitting angles and the brightness of the first light-emitting area and the second light-emitting area are different. In the first light emitting region, the cross section of the incident surface 313 along the direction perpendicular to the central axis is a plane, and the cross section of the emitting surface 314 along the direction perpendicular to the central axis is a curved surface protruding outwards in the direction away from the incident surface 313.
In the second light emitting area, the cross section of the incident surface 315 along the direction perpendicular to the central axis is an inclined surface, which may be a curved surface or a flat surface, in this embodiment, a flat surface, and the inclined surface is inclined from the outside to the inside in a direction away from the light source plate 32; the cross section of the emergent face 316 along the direction vertical to the central axis is a curved face protruding outwards towards the direction away from the incident face 315; and the radius of curvature of the exit face 316 of the second light exit region is smaller than the radius of curvature of the exit face of the first light exit region. Through the design, the second light-emitting area can well collimate light rays, so that light distribution with a small light-emitting angle of about 40 degrees is formed.
In order to further improve the light extraction rate of the first light extraction area and shield the LED patch light source 321, the incident surface of the first light extraction area is composed of a plurality of concentric circles, and each concentric circle is convex towards the direction close to the light source plate 32. In order to further increase the light emitting width of the second light emitting area and shield the LED patch light source 321, the incident surface of the second light emitting area is composed of a plurality of ribs extending along the radial direction, and the ribs are convex toward the direction close to the light source plate 32. Therefore, the width of the second light emergent area in the automobile tail lamp is wider than that in the prior art, so that the light effect of the second light emergent area is more obvious and striking.
In the present embodiment, the first total reflection surface 311 and the second total reflection surface 312 are arranged as follows: a recess 317 extending away from the light source plate 32 is formed between the outer periphery of the incident surface 313 of the first light emergent region and the inner periphery of the incident surface 315 of the second light emergent region, and the width of the recess 317 is gradually reduced toward the direction away from the light source plate 32; the first total reflection surface 311 and the second total reflection surface 312 are formed on both side walls of the recess 317.
Finally, in this embodiment, the thickness of the outer wall of the lampshade 2 is equal everywhere.
The present invention is not limited to the above-mentioned embodiments, and any changes or substitutions that can be easily understood by those skilled in the art within the technical scope of the present invention are intended to be included in the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
