How to Identify the Quality of LED Headlamp Bulb


LED headlamp bulbs identify the quality of good or bad, mainly to see a scattered one together. Is the cooling cooling problem, poly is the problem with the condenser light.

Solve the problem of poor heat, the first impact LED bulb life, the second impact of power and light efficiency thus affecting the luminous flux output of the lamp.

Condenser problem solving is not good, the first effect of the use of light efficiency, the second will produce glare to the other drivers driving interference, affecting traffic safety.

LED lights on the market light bulbs, cooling in two ways: fan cooling and metal braided belt cooling. Fan cooling problem is to increase energy consumption, the second is noise, three fan life determines the lamp life - and fans in the lamp cavity inside the local high-temperature space environment, the service life is often very short. Metal braided cooling of the bulb, the test results are also very general, LED junction temperature of most of the work of up to 110-120 degrees, light bead because the high-temperature light failure will soon darken.

Therefore, these two kinds of cooling LED headlamp bulb life in general will not be more than two years, the quality is less than half a year. This is the current status of LED car headlamp bulb market.

As for the condenser problem, light bulb light area (such as COB) light bulb, condenser performance is very poor. Select the original car halogen light source similar to the LED lamp beads type, condenser performance will be better.

At present, the market, virtual standard power, virtual standard luminous flux, virtual standard life is very common.

Virtual standard power: the product nominal power 30w, 40w, the actual solution to the problem of poor heat only to do more than ten twenty watts.

Virtual standard luminous flux: The practice is to install the lamp in all the LED maximum power flux, add 4000 lm 5000 lm or even 6000 lm is the product luminous flux. And in fact simply can not do, poor or even less than halogen lamp 1200 lm brightness.

Therefore, the global market is very looking forward to a really good solution to the problem of perfect condenser condenser halogen bulb can replace the LED car headlamp bulb!
