Universal LED heat-dissipation vehicle lamp made from aluminium base material, and machining method thereof

Abstract

The invention relates to a universal LED heat-dissipation vehicle lamp made from an aluminium base material. The universal LED heat-dissipation vehicle lamp comprises a lamp body made from the aluminium base material, wherein a heat-dissipation part is integrally arranged at the upper end of the lamp body; a light-emitting part is arranged at the lower end of the lamp body; a plurality of installation grooves are formed in the heat-dissipation part, and penetrate through the upper part of the lamp body and extend to the light-emitting part; light-emitting bodies are arranged on the light-emitting part and in the installation grooves; a power supply accommodating groove is formed in the middle part of the upper end of the lamp body; the heat-dissipation part comprises a plurality of heat-dissipation sheets arranged in a manner of being dispersed from the lamp body to the outer side; and a heat-dissipation fan is arranged at the centre or one side of the heat-dissipation part. According to the universal LED heat-dissipation vehicle lamp disclosed by the invention, the heat-dissipation part is arranged at one side of the lamp body, and then the heat-dissipation fan and the power supply accommodating groove are staggered in position, so that more flexible position selection is provided for installation for the heat-dissipation fan, the length of the vehicle lamp is effectively shortened, the universality of the vehicle body is improved, and then the usage rate of resources is greatly increased, and the production cost of the vehicle lamp is lowered; and because the lamp body and the heat-dissipation part are integrally designed, the heat-dissipation effect of the lamp body cannot be influenced due to the position change of the heat-dissipation part.

Description

technical field [0001] The invention relates to the field of lighting, in particular to a general-purpose LED heat-dissipating vehicle lamp with an aluminum substrate. Background technique [0002] LED car lights refer to car lights that use LEDs (light-emitting diodes) as light sources. Because LED has the characteristics of high brightness, rich color variety, low power consumption, and long life, LED is widely used in the automotive field. Headlights, commonly known as "headlights", are installed on both sides of the head of the car to illuminate the road in front of the car. There are two-lamp system and four-lamp system. When the four-lamp system headlamps are installed side by side, the pair installed on the outside corresponds to the near and high beam double-beam lamps; the pair installed on the inside corresponds to the high-beam single-beam lamp. The high beam is generally 40-60W, and the low beam is generally 35-55W. [0003] The existing headlight lamp body a...

AI Technical Summary

Problems solved by technology

There are many types of headlight lamp bodies, which lack versatility. For many cars, only a few suitable lamp bodies can be selected. After damage, only the original headlights can be replaced, which is very troublesome.

The main reason is that the design of the heat sink, cooling fan and power supply of the lamp body is compact, and the space for modification is very small. The distance from the conventional car light clamp to the top surface of the car light is within 30mm. If it exceeds this distance, it will be difficult to install the car light. A cooling fan needs to be installed above the card position, so the conventional lamp body is easy to be too long and interferes with the dust cover during installation. Even if the lamp body is standardized, different cars have different design concepts, and the length of the lampshade is also different. Therefore, it is difficult to achieve the versatility of the lamp body, causing great trouble to users

Many models only have a single type of suitable headlights, resulting in a situation where one model corresponds to one type of headlight.
