Analysis of the causes of LED high bay light decay


Abstract: Because the luminous power of LED high-power high bay lights is greater than that of household lamps, LED high bay light manufacturers have worked hard on the design of heat dissipation substrate fins and heat dissipation modules.


       Because the luminous power of LED high bay high bay lights is greater than that of household lamps, LED high-bay light manufacturers have worked hard on the design of heat dissipation substrate fins and heat dissipation modules. After assembling high-power high bay lights, baking paint must be applied to the outside of the heat dissipation module of the lamp. Protect it from weather corrosion, otherwise the spray paint of this external protection seals the heat of the heat dissipation module back, resulting in poor heat dissipation and causing the LED high-power industrial and mining lights to decay.

 

LED high bay manufacturers analyze the causes of light decay:

1. LED high bay are used outdoors, and there are factors that disturb the climate. Therefore, most manufacturers use anodized protection on the radiator shell of LED high bay, or spray paint to avoid acid and alkali substances. Corrosion, the anode treatment life is not long, and after a while, it will still oxidize and change color. If the heavy industry is to be removed, it will not only consume time and labor, but also increase maintenance costs. The paint protection cost is low, and the protection effect is good. However, the general baking varnish has no heat dissipation function, and the lacquer itself will form an insulation effect, which is equivalent to adding the thermal resistance of the high-power LED high-bay lamp radiator. Not only is it not helpful, but because the heat is enclosed in the metal halide lamp radiator, the LED The decrease in luminous power will eventually lead to severe luminous decay.

 

2. The luminous heat energy of LED high bay belongs to small-scale concentrated heat energy. When using high-power street lamps, the power input power is also large, and the temperature of the LED interface is quite high. Under the long-term continuous operation of the street lamp, the heat dissipation module is not Can not effectively dissipate heat, and then affect the life of the LED and the luminous expression. The serious light decay of the LED high-power high bay lamp is formed by these factors.
