Description

Technical Field

[0001] The present invention belongs to the field of lamps in vehicles, and in particular, the present invention relates to an LED combination lamp comprising a front turn signal lamp, a daytime running lamp and a front position lamp. Background Art

[0002] Daytime running lights refer to lights that make it easier for vehicles to be identified when they are driving during the day. They are installed on the front of the vehicle body. When the vehicle engine is started, the daytime running lights turn on automatically to attract the attention of other motor vehicles, non-motor vehicles and pedestrians on the road. Their main function is to let others know that a car is coming, and they belong to the category of signal lights.

[0003] There are many types of optical systems for LED daytime running lights. At present, the mainstream market is dominated by light-guiding design, which can be designed into a three-dimensional curved surface according to the shape, with beautiful shape and flexible structure. Figure 1 As shown, it is an optical schematic diagram of a light-guiding structure, where 101 is a metal circuit board that provides heat dissipation and circuits for 102 LED, 102 is an LED, and the light emitted by it is converted into a convergent surface light source after TIR refraction and total reflection through the optical structure 1031, and then the light is totally reflected through 1032, and part of the light is totally reflected and then refracted through the surface 1033. The design disadvantages of this light-guiding structure are: the light has a long path in thick-walled materials, and the light is totally reflected through multiple surfaces, the light loss is very high, the light utilization rate is low, and higher power is required. The injection molding process of thick-walled optical parts is complicated, and the mold cost is high. At the same time, the LED emits light from the side of the optical part 103, the side area is small, and the LEDs are dense, which is not conducive to heat dissipation.

[0004] Figure 2 It is a circular light guide design in the prior art. 201 is a metal circuit board that provides heat dissipation and circuits for 202LED. The light emitted by 202LED is converted into a converging surface light source after TIR refraction and total reflection by 2031 optical structure. The surface light sources on the left and right sides are totally reflected by the circular cylindrical surface 203 and the toothed structure 2033 at the bottom, and finally a circular light band is formed. However, there is a square structure at the LED that does not emit light, and there is a gap in the circular light band.

[0005] Figure 3It is a circular TIR optical design in the prior art. 301 is a metal circuit board that provides heat dissipation and circuits for 302LED. The light emitted by 302LED is refracted and totally reflected by the TIR optical structure of 3031, which converts the point light source of 302LED into a convergent surface light source, and then diffuses through the surface particles of 3032, so that the light meets the daytime running light standard. The design features of this structure are short light path and high light utilization rate. At the same time, the LEDs are arranged separately in a circle, which is conducive to heat dissipation. However, some customers do not like this structure with a granular appearance. They prefer the surface 3032 to be a smooth curved surface with a metallic stripe texture. Summary of the invention
