How to identify high-power LED chips

Given the chaotic status of led outdoor lighting wholesale market competition in the market , many businesses took a vicious price war for consumers little time understanding the LED chip is also a very difficult thing .
The main reason is :

1, no professional equipment

2, the purchase is finished , there is no single test sample

3, LED chip -related knowledge to understand too little.

First let us look at the cognitive LED chips. What is LED? Is simply light-emitting diodes. In earlier years the use of LED is mainly used as an indicator in the circuit. With each passing day can , LED technology has become increasingly mature, has gradually expanded field of use , LED lighting gradually enter the market and widely used in all aspects of life lighting .

Today we are in contact with or knowledge of LED products mainly , what does ? LED TV , LED display, LED flashlights and other LED products are the most common . For the lighting industry are LED Downlight , LED ceiling lamps , LED fluorescent tube , and 2012 before the rise of the LED panel lights , and other products .

LED compared to traditional incandescent and energy-saving lamps have what advantage can make it inevitable to replace traditional lighting products?

The main product advantages:

( 1 ) low-carbon energy saving and environmental protection. This is the LED products will replace the traditional lighting of the main advantages , he compared to traditional incandescent bulbs 90% , compared to 50% of energy-saving lamps .

( 2 ) style diversification . Whether it is traditional incandescent also traditional energy-saving lamps , sodium lamps and other lighting products even so far can only stay in the shape of the bulb and lamp stage . LED lamps exist today in many forms , in addition to catering to the traditional lighting LED bulb produced and LED fluorescent tube , also spawned a large number of different shape lamps, including lights, string lights, light bar , modules , wall , crystal lamps and other products. Big can be used for outdoor advertising lighting , LED landscape lighting project Spotlights , landscape ; small can of green beans so small small LED light strings .

( 3 ) Other superior performance. If no flicker, no lead and mercury , no radiation , high brightness , low heat and so on.

Although there are so many LED products have merit , but from the practical point of view , LED columns are still some problems in the current popularity. Mainly due to: ( 1 ) chips and other core technology in the hands of Japan and USA and other developed countries , a small number of domestic self-developed chips , poor product quality. ( 2 ) Despite the vast land of China , but the rural areas of information obstruction, coupled with cognitive science and technology behind today's LED products promotion only just stay in the cities.

Nevertheless, many businesses still feel the trend of development of LED lamps , LED lamps vigorously in promoting universal . However, in such a competitive environment does not inevitably produce a vicious market competition. LED vicious competition in the market is mainly reflected in ( 1 ) the use of inferior materials businesses produce products , not cheap but make consumers' interests are protected. (2) LED is a new product before the rise in recent years , the state does not have a sound management system , product quality can only be decided by the market. ( 3 ) the interests of businesses exist in the final stages of the manufacturing sectors , the profit is very low, forced to take extreme strategy.

Therefore, there is a lot of shoddy market products , the most obvious is to replace inferior quality lamp beads lamp beads, lamp beads and differentiate the most obvious place is the chip.

How chip identification, for the average person is a very difficult problem , the type of chip determines the quality of the product, determines the length and quality of life of the lighting effects .

Here we use the simplest method of identification of the identification chip lamp beads lamp beads .

First of all the tools we need are:

Tweezers, magnifying glass

Part II : Preparing a high-power led outdoor lighting wholesale beads

Part III: Our lamp beads with tweezers or by hand peeling surface potting silicone, see Sesame size LED chips. Then use a magnifying glass to see the lines of the chip lamp beads are consistent with the known lamp beads and chips , general product packaging external chip lamp beads have described .
