High-efficiency and high-uniformity automobile position lamp arrangement structure

Abstract

The invention discloses a high-efficiency and high-uniformity automobile position lamp arrangement structure. The high-efficiency and high-uniformity automobile position lamp arrangement structure comprises a thick-wall light guide and a reflection bowl, wherein the reflection bowl is movably installed on the back face of the thick-wall light guide, the thick-wall light guide is formed in a double-color injection molding mode, the thick-wall light guide comprises a thick-wall light guide light-emitting face and a thick-wall light leading-in face, the front face of the thick-wall light guide isfixedly connected with the thick-wall light guide light-emitting face, and the back face of the thick-wall light guide light-emitting face is fixedly connected with a light inlet face of the thick-wall light guide light-emitting face. The high-efficiency and high-uniformity automobile position lamp arrangement structure is provided with the reflection bowl; the design of a signal lamp with a plurality of strip-shaped lamp strips is realized through the double-color injection molding thick-wall light guide and the reflection bowl; light coupling design is carried out to achieve high efficiencyand high uniformity in light distribution and lighting uniformity of position lamps; the number of parts in the lamp can be reduced, the LED power can be reduced, the structure is simple, the light emitting is uniform, the cost is low, the vibration fracture risk is small, the advantages are obvious, and the high-efficiency and high-uniformity automobile position lamp arrangement structure is suitable for automobiles.

Description

Technical field [0001] The invention relates to the technical field of automobiles, in particular to a high-efficiency and high-uniformity automobile position lamp arrangement structure. Background technique [0002] In order to ensure that other vehicles can see the length and width of the vehicle they are driving at night, and to avoid traffic accidents, position lights are installed on the front and rear of the body. However, position lights do not need to be used during the day. With rapid development, automotive position lights have evolved from traditional bulbs to LED light sources. LED light sources have the characteristics of small light-emitting area, large luminous flux, energy saving, and large design freedom. LEDs have become the mainstream trend in the field of automotive lights. In response to the increasing and diversified needs of customers for the appearance of automobiles, LED position lights have evolved from a single point-like appearance to high luminous uni...

Problems solved by technology

[0003] Nowadays, the shape of cars on the market is more and more technological, and the lights are also highly ornamental exterior parts. The future shape trend of car lights will continue to be flat and refined. Flattening will inevitably compress the internal space of lights. , it requires more efficient lighting design, and refinement requires improved lighting uniformity; when the shape of the signal light is multiple strip light strips, in the existing technology, it is often used to arrange behind each strip light strip Reflective bowls and LEDs are used to light up the light strips. This will increase the number of reflective bowls, PCBs, and LEDs, and the cost will increase accordingly. The power of the lamps will increase accordingly, and the risk of vibration and fracture will increase accordingly. Therefore, there are many disadvantages
