Description

A spliced street lamp radiator

technical field

The utility model relates to a radiator, in particular to a spliced street lamp radiator.

Background technique

At present, the LED street lights on the market cannot be adjusted. Therefore, if high-power LEDs are used to meet the light intensity in rainy and hazy weather, it will cause waste of power in an environment with better visibility; if low-power LEDs are used, However, in environments with poor visibility such as rainy days, it cannot meet the light intensity requirements.

At the same time, LED is an electroluminescent device. Only 15% to 25% of the electrical energy is converted into light energy during its working process, and the rest of the electrical energy is almost converted into heat energy, which increases the temperature of the LED and causes a sharp drop in light efficiency. If the temperature is too high, the LED will be damaged due to overheating. The heat dissipation of LED street lamps is one of the key problems that need to be solved. It is not only directly related to the luminous efficiency of LEDs in actual work, but also due to the high brightness requirements of LED street lamps, large heat generation, and the harsh outdoor environment, if the heat dissipation is not good It will directly lead to rapid aging of LEDs and reduced stability.

Most of the existing LED street lamp heat sinks are designed as integral die-casting. This type of heat sink cannot be designed in the most reasonable way according to the actual heat generation, and the heat dissipation effect is poor. In maintenance, because the lamp beads also adopt the overall layout, maintenance is more complicated. Whole replacement is adopted, and the maintenance cost is high.
