How to avoid excessive light failure LED lamps

First, choose what kind of LED lamps.

This is important, the quality of LED lamps can be said to be a very important factor. For some examples, the same white with Epistar 14mil chip segment represented to do with ordinary epoxy primer and white plastic packaging and packaging glue out of the LED lamps, the single lit environment at 30 degrees, one thousand hours later, the attenuation data for the light fades 70%; If class D low decay glue package, in the same aging environment, thousands of small-time decline of 45%; If the class C low decay glue package, in the same aging environment, thousands of small-time decline of 12%; if class B low decay glue package, in the same aging environment, thousands of small-time decline of -3%; If class A low decline glue, aging in the same environment, thousands of small-time decline -6%.

Secondly, LED lamp beadwork ambient temperature.

According to the data when a single LED lamp aging perspective, LED lamps to work if only one is lit, while the temperature of the environment is 30 degrees, then, stand temperature single LED lamps at work does not exceed 45 degrees. This time, the Fengyun LED life will be very satisfactory.

If there are 100 LED lamps lit simultaneously work interval between them is just 11.4mm case, then the temperature of the surrounding stent LED lighting lamps heap may not exceed 45 degrees, but the heap in the middle of those LED lights the lamp has a high temperature may reach 65 degrees. This time, the LED lamp beads are a test. So, for those gathered in the middle of the LED lamps, the light fades will theoretically faster, but the lamp heap surrounding LED lamps, light failure will slow down a bit. led grow lights https://www.eneltec-led.com/products/led-grow-lights

Anyway, everyone should know, LED is sensitive to heat, the higher the temperature, the shorter the LED life, the lower the temperature, the longer the LED life. Of course, the ideal LED operating temperature is between negative 5 to zero. But this is basically impossible.

Again, LED lampwork beads electrical design parameters.

According to the results, in LED lamps at the lower drive current situation, the heat emission is smaller, of course, the smaller the brightness. According to the survey, design LED solar lighting circuits, LED drive current is generally just 5-10mA; a number of lamp beads with large lamps used products, such as reach 500 or more, or more, the drive current is generally just 10-15mA, and the general popularity of LED lighting applications drive current, just 15-18mA, rarely some people more than the current design to 20mA. best led headlights http://bestledheadlight.com/

The results also show that the drive current of 14mA, and added a lid unventilated, the inside air temperature reaches 71 degrees under an environment of low decay products, thousands of small-time decline to zero, 2000 small-time decline of 3%, which indicates that this low attenuation LED lamps used in such an environment has reached its maximum, and then big is the kind of damage it.
