What Effects Does High Temperature Have on the Reliability of High Bay Lighting Product?

The reliability of high bay lighting product are influenced by many environmental factors .high temperature is one remarkable factor of them. High temperature have major changes in the lifespan of high bay lighting product.  most industrial lighting products on the market don't have the ability of continually operating in high temperature environment . if these lights exposed to high temperature for long periods of time , their performance drops significantly and you will find that you need to pay more for replacing the broken lights  and further affect the work efficacy of your workshop . 

high bay lights that can work in high ambient temperature is undoubtedly the required product in consumers' mind . to design and manufacture such a product , we must first understand some things about the effects of high temperature on the reliability of product. the workshops of metallurgical, die-casting and machining are common occasions where ambient temperature is high.

the effect of high temperature on product

1) numerous researches have linked the damage of LEDs to increased temperature of luminaires' chamber. LEDs is the soul of luminaires. excessive temperature will burn out LEDs.  it is difficult to form a temperature difference to conduct the produced heat if luminaires work in a high-temp environment.

2)For the reason different materials have different expansion coefficients, the air-tightness of product may change because of the displacement due to expansion on some components . a product that originally you was going to use in normal temperature ,in many cases ,is unfit for hot environment.

3)If your products have to use lubricant, high temperature will make lubricant run off and reduce the lubricating property. The abrasion of product components will increase on account of low lubricating performance. Over time, products will break down.

4)High temperature will give rise to deformation of packing,gasket,seal,bearing and rotation axis etc. These deformations will have a big adverse impact on the IP rating of lighting product.

5)Risk pf product failure in operating in high-temp environment is high. High temperature has been found to  change of the electrical parameter and affect the electric performance of products , especially some highly correlated parameters. A small change could have a huge influence.

6) for some organic materials ,high temperature will easily lead them to bad outcomes like  aging, discoloration, foaming, cracking etc. these adverse signs are known to mean a cut-off lifespan for lighting products. and these changes visible to the naked eye make consumers easily judge the quality of product.

7)in principle,high temperature has a higher requirement of circuit . a weak circuit in a high temperature environment will make lighting products serve as a bomb with potential danger. Once temperature exceed limit value , the circuit will be fused or sparking. if there is full of combustible gas and explosive dust in the space , this will significantly increase the possibility of combustion or explosion. a over-heat product will become the origin and blasting fuse of those terrible accidents .

8) temperature rise will reduce the air pressure in the body of lighting fixture, resulting in an unbalance of internal and external pressure. stronger atmospheric pressure outside the lamps squeeze the constituent elements of lights,which eventually lead to some unrecoverable warps ,even make the lighting structure no longer stable. in recent years , the owners of high-temp plant have noticed that and actively look for more durable products to replace original lights so as to solve the problem.

9)The properties of insulating materials are closely related to temperature. in order to ensure the insulation performance, each insulation material is specified a maximum allowable operating temperature, below which the insulation material can be used safely for a long time. however ,we all know that the higher the temperature, the worse the insulation.high temperature will worse the insulating property of materials .

progressing to lighting products that claimed to be available for high-temp environment is a logical step as it practically helps reduce the damage rate and replacement cost of lighting devices. you can get your high bay light product that suit high-temp environment here :https://www.agcled.com/product-detail/hb31.html?from=sopl
