Abstract
Description
Technical Field
[0001] This utility model relates to the field of LED automotive lighting technology, specifically to a reflector cup wall for an LED automotive light. Background Technology
[0002] LED bulbs are small and lightweight, encapsulated in epoxy resin, making them resistant to high-intensity mechanical shocks and vibrations, and less prone to breakage. They also have a long brightness decay period, resulting in a lifespan of 50,000-100,000 hours. In summary, LEDs are widely used in automotive lighting systems due to their durability, reliability, long lifespan, faster response time, low energy consumption, compact size, and greater design flexibility. LEDs offer fast response times, down to nanoseconds, allowing drivers of following vehicles to be alerted to driving conditions earlier, reducing the occurrence of rear-end collisions.
[0003] The heat dissipation effect of the reflector cup wall in existing LED automotive lights is not good, which leads to accelerated decay of the brightness of LED lights and the lifespan of circuit components. Under prolonged irradiation, the temperature of the reflector cup wall, which is used as a headlight, is difficult to reduce. After long-term use, it affects the lifespan of the reflector cup wall and the LED light. Utility Model Content
[0004] The purpose of this invention is to provide a reflector cup wall for LED car lights, which facilitates rapid heat dissipation inside the LED car light and extends the overall lifespan of the LED car light.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a reflector cup wall for an LED automotive light, comprising a cup body, a reflector wall fixedly connected to the inner wall of the cup body, a mounting cavity fixedly connected to the top of the cup body, an LED light extending to the inner side of the reflector wall installed inside the mounting cavity, a plurality of evenly distributed heat dissipation sleeves provided on the outer wall of the cup body, heat-conducting sheets fixedly connected inside the heat dissipation sleeves, one end of each of the plurality of heat-conducting sheets extending into the interior of the mounting cavity, and air ducts formed between the heat-conducting sheets and both sides of the inner wall of the heat dissipation sleeves.
[0006] To improve heat conduction, the heat-conducting sheet of the reflector cup wall of the LED car light of this utility model is preferably made of copper.
[0007] To facilitate heat conduction, in a preferred embodiment of the reflector cup wall of this LED automotive lamp, the end of the heat-conducting sheet located inside the mounting cavity is fitted against the inner wall of the mounting cavity.
[0008] In order to refract light, the reflector cup of the LED car light of this utility model preferably has a lens fixedly connected inside the cup body, located below the LED light.
[0009] In order to fix the heat sink, as a preferred embodiment of the reflector cup wall of the LED automotive light of this utility model, multiple connecting rods are fixedly connected between the heat sink and the cup body.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0011] The LED light extends to the inside of the reflector wall, hitting the reflector wall and the lens. After being refracted by the lens, the light becomes parallel and is emitted. The lens includes a convex lens and a concave lens, which are responsible for the low beam and high beam respectively. The heat generated by the LED light during operation is concentrated inside the mounting cavity. Multiple heat-conducting plates extend into the mounting cavity and abut against its inner wall, thereby absorbing the heat inside the mounting cavity and dissipating it outward. When the vehicle is in motion, air enters the interior of the heat sink through multiple air ducts, thereby quickly dissipating the heat from the heat-conducting plates. This rapid heat dissipation inside the mounting cavity extends the overall lifespan of the LED automotive light. Attached Figure Description
