However, the input power of the LED is about 50% to 80%. It becomes heat, and when it accumulates above 80 °C, it will greatly reduce the LED light-emitting performance and shorten the LED life.

Moreover, since the light of the conventional LED lamp is mainly caused by the reflection of the mirror, the light is emitted forward, and the light is easy to lose power when reflected, and if the light is to be changed in angle, brightness, and illumination range, it must be adjusted. The reflective curved surface of the mirror and the reverse surface structure are designed to achieve.

In order to achieve the above object, the present invention provides a vehicle lamp structure, comprising: a front cover, a plurality of first positioning holes are arranged around the front cover, and a receiving hole is arranged in the center; and a light guiding lens is provided. The illuminating device is disposed in the accommodating hole of the front cover, and the light guiding lens has a light emitting portion and a light incident portion, and a receiving groove is disposed at the light incident portion; and a light emitting device is disposed in the cavity The LED is disposed at a central position, and the LED illumination direction is directed toward the light entrance portion; a lamp holder is provided with a plurality of second positioning holes around the socket, and a slot seat at the center, and is in the center of the slot a slot is defined in the slot, and the slot is correspondingly coupled to the light guiding lens, and the slot corresponds to the lower side of the light emitting device; and a heat dissipating module has a cavity, and the peripheral wall of the cavity has a plurality of The heat dissipation fins are provided with a plurality of positioning pillars, and the positioning pillars sequentially pass through the second positioning holes and the first positioning holes to fix the lamp holder and the front cover above the cavity of the heat dissipation module.

The light incident portion has a curved surface portion convex toward the light exit portion.

The above-mentioned light exiting portion also has a pair of arc convex surfaces which should be curved in the curved surface portion.

Thereby, the LED light-emitting direction of the present invention is directed toward the light-injecting portion, and the light-using efficiency and light-type control of the present creation are made by the arrangement of the light-incident surface and the light-emitting surface of the light guiding lens and the arrangement position of the light-emitting member. Good, and can produce high brightness and uniform illumination.

The heat source generated by the operation of the light-emitting device can be directly discharged into the cavity of the heat-dissipating module through the slot of the lamp socket, and the heat dissipation effect of the heat-dissipating fins is obtained.

In order to enable your review committee to have a better understanding and understanding of the purpose, characteristics and efficacy of this creation, please refer to the following for details: Please refer to Figure 1~3. This creation includes a front cover and a guide. The light lens 2, a light-emitting device 3, a lamp holder 4 and a heat-dissipating module 5, wherein the front cover 1 has a receiving hole 11 in the center thereof, and has a plurality of first positioning holes 12 around the receiving hole 11.

The light guide lens 2 is disposed in the accommodating hole 11 of the front cover 1 , and the light guide lens 2 has a light exit portion 21 and a light incident portion 22 , and a receiving groove 221 is provided at the light incident portion 22 . In the embodiment, the light incident portion 22 has a curved surface portion 222 that is convex toward the light exit portion 21, and the light exit portion 21 also has a pair of arc convex surfaces 211 that are curved by the curved surface portion 222.
