Column type led radiator

Abstract

The invention relates to a column-type LED (light-emitting diode) radiator capable of effectively increasing heat dissipation area, improving the heat dissipation effect and is in favor of installation. The column-type LED radiator disclosed by the invention comprises a base and a heat dissipation assembly; a power supply mounting table and a light source mounting groove are respectively arranged at the top part and the bottom part of the base; the heat dissipation assembly comprises a heat conduction sleeve, a plurality of cooling fins and a heat dissipation ring; the heat conduction sleeve is sheathed at the outer side of the power supply mounting table, and a gap is formed in the heat conduction sleeve; the cooling fins are vertically and fixedly arranged on the outer side face of the heat conduction sleeve; the heat dissipation ring is sheathed and supported to outer ends of the cooling fins; oblique planes matched with each other are respectively arranged at outer sides of the cooling fins and the inner side of the heat dissipation ring; the bottom part of the heat dissipation ring is also provided with a fixed part; a hold down groove matched with the fixed part is formed in the base.

Description

technical field [0001] The invention relates to an automobile headlight radiator, in particular to a column type LED radiator. Background technique [0002] With the rapid development of the automobile industry, while people are pursuing comfort and ease of handling, more and more attention has been paid to the overall safety, energy saving and environmental protection of the automobile. In this regard, in order to reduce the energy consumption of automobile lighting, the existing technology Car headlights usually use LED lights and adopt planar cluster packaging technology to meet the requirements of high power and low energy consumption; however, the interior of car headlights is a closed environment. When the car headlights are in the lighting state, the headlights The closed environment where the lamp is located will generate a higher temperature due to heat accumulation, which will not only easily generate fog inside the headlight and affect the lighting effect, but als...

[0002] With the rapid development of the automobile industry, while people are pursuing comfort and ease of handling, more and more attention has been paid to the overall safety, energy saving and environmental protection of the automobile. In this regard, in order to reduce the energy consumption of automobile lighting, the existing technology Car headlights usually use LED lights and adopt planar cluster packaging technology to meet the requirements of high power and low energy consumption; however, the interior of car headlights is a closed environment. When the car headlights are in the lighting state, the headlights The closed environment where the lamp is located will generate a higher temperature due to heat accumulation, which will not only easily generate fog inside the headlight and affect the lighting effect, but also easily cause the parts in the car headlight, especially the plastic parts, to be deformed by heat. There is even a phenomenon of melting; at present, using an aluminum radiator to cool down is a common way of heat dissipation. However, in this way, if the heat sink is too large, it is easy to hurt people and is not conducive to installation and use. If the heat sink is too small, it is not conducive to heat dissipation.
