The use of LED street lights is becoming more and more widespread. Except for the LED lighting technology, the rest are LED street light housings. Below,Aluminum Lamp Housing Supplier will introduce the precautions for purchasing LED street light housings:

When purchasing an LED street lamp housing, we should first clarify the power that the LED lamp needs to dissipate. Generally speaking, some parameters for the heat sink should be provided, such as the specific heat of metal, the thermal conductivity of metal, the thermal resistance of the chip, the thermal resistance of the radiator, the thermal resistance of the surrounding air, etc. Then determine the type of heat dissipation, natural convection heat dissipation,strong wind cooling, heat pipe heat dissipation, and other heat dissipation methods. Compared with natural convection, the cost of heat dissipation is low, the cost of strong wind cooling is medium, the cost of heat pipe heat dissipation is relatively high, and the cost of air-jet cooling is high.

When choosing the LED street lamp housing, you should also determine the high operating temperature permitted by the LED lamp (ambient temperature plus the permitted temperature rise of the lamp). In this regard, attention should be paid to combining the radiator and the LED lamp into a complete lamp, and powering it for more than eight hours. Check the temperature of the luminaire at a room temperature of 39℃--40℃ to see if it meets the heat dissipation requirements to verify whether the calculation is correct. If it does not meet the conditions of use, recalculate and adjust the parameters. The sealing of the radiator and the lampshade of the LED street lamp housing should be waterproof and dustproof. The anti-aging rubber pad or silicon rubber pad should be placed between the lampshade and the radiator, and the stainless steel bolt should be used to fasten it to ensure the seal is waterproof and dustproof.

The heat dissipation aspect of the LED street lamp housing determines the use time and lifespan of the LED street lamp. Therefore, you must pay more attention when choosing the LED street lamp housing, because it is related to its service life. If it can not dissipate heat well, it will be a disaster for the LED street lamp.

Through the above introduction,High Lumen Street Light Housing Manufacturers hopes that you can simply refer to the content of this article in future use.
