Identification of LED car headlamp bulb quality method

<p>Identification of LED car headlamp bulb quality is good or bad, mainly to see a scattered together. Scattered is the cooling problem, poly is the light distribution problem. Cooling problem is not good, the first impact on the life of LED bulbs, the second impact on power and light effects thus affecting the output of the light flux. Concentration solution is not good, the first impact on the use of light efficiency, the second will produce glare to the other driver caused interference, driving safety. <a href="http://www.motorlighting.com">Jeep LED light bars</a></p>

<p>LED bulbs on the market, there are two ways of cooling: fan cooling and metal braid with heat. Fan cooling problems First, increase the energy consumption, the second is the noise, the third is the fan life determines the lamp life - and fans in the lamp chamber inside the local high temperature space environment life is often very short. Metal braided with heat bulbs, the test results are also very general, most of the LED junction temperature up to 110-120 degrees, the lamp beads due to high temperature fades will soon become darker. Therefore, these two kinds of heat dissipation LED headlamp bulb life is generally not more than two years, the quality is less than six months to less than. This is the current LED car headlamp bulb market situation. As for the condenser problem, light bulb area (such as COB) light bulb, condenser performance is very poor. Choose the original car halogen light source similar to the LED lamp beads type, condenser performance will be better. <a href="http://www.motorlighting.com/fog-light/2957.html">Compact Fluorescent Lamp Wikipedia</a></p>

<p>At present the market, virtual standard power, virtual standard luminous flux, virtual standard life is very common. Virtual standard power: product nominal power 30w, 40w, the actual problem is not good because the heat to solve more than ten twenty watts. Virtual standard luminous flux: the practice is to be installed in the lamp all the LED maximum power luminous flux added, then marked 4000 lm 5000 lm or even 6000 lm is the product luminous flux. And in fact simply can not do, even worse than halogen light bulb 1200 lm brightness. So, the global market is very much looking forward to a really good perfect solution to heat dissipation problem can replace the halogen bulb LED car headlamp bulb appears! <a href="http://www.motorlighting.com/fog-light/225.html">Lighting In Ground Swimming Pool Lighting Hayward Pool</a></p>
