Analysis of the main reason for the price difference between LED lamps

The pursuit of high quality and inexpensive goods to consumers is nature, but at this stage you want to buy a LED lamp low price and a good quality, there are still more difficult. When we buy LED lamps will find that, even with the same price difference between the LED lights are large, then the difference in there?

First say LED and energy-saving lamps. In large shopping malls, a second tier brand of spiral 20W energy-saving lamps priced at 59 yuan. The equivalent of a LED10W lamp in the price of 38 yuan to 120 yuan. You can imagine, energy-saving lamps, compared with LED, no technical content of LED is high, but some LED less than the price of energy-saving lamp, only 38 yuan, really LED cost dropped to energy-saving lamps below, at this stage, it is difficult to; then 100 yuan LED downlight is high in there? Is the main chip, driving power and heat dissipation material.

Say LED up. A 15W LED downlight, the same manufacturer, look the same, but only one may vary widely in price; if a 15W LED is made by SMD, another is the use of high-power chip, the cost is not the same, of course, the price is not the same, obviously is the power to do to the high cost, the price will naturally be higher.

Analysis of the main reason for the price difference LED lamp

Therefore, the price difference is mainly in the following LED:

Chip: foreign chip is genuine or non genuine? Is that a Foreign Legion in Europe and the United States is first-class? CREE, OSL and others such as Puri, Japan Nichia; TOYOTA synthesis, Seoul semiconductor, is also quite good; Taiwan Jingyuan, the new century is the corresponding end, domestic chip price is low.

Package: the same is the use of a relatively good chip, the package is the original package or self packaging, is the use of epoxy resin or silica gel is the use of double gold or single line, etc., which have an impact on prices.

Is the chip with a high power LED or SMD to do the light source of high power of course a little better. If you do with SMD light source, then the specification is 3528 or 5050 or other, and so on, of course, different specifications of the cost is not the same, the price is not the same.

Drive circuit is constant voltage or constant current, if the constant current is how to use constant current circuit, stability and reliability, etc.. Some low-end LED lamps because of the use of low-cost LED drive, with a few months or even a few days time, the trial will be a flash, which is caused by the poor driving power, of course, this kind of inferior LED lamps prices lower.

Cooling mode; have a great relationship with the LED life of heat, the heat is not good, life is very serious, problems soon.

Heat dissipation material: at present, most of the domestic LED lamps are made of aluminum material heat dissipation, then use die casting aluminum and aluminum alloy with heat, the effect is not the same, the latter of course, high cost, heat dissipation effect is good.

The appearance of the process: a needless to say, consumers will be able to see it, especially to say, there are some "visceral is poor", but the LED lamp appearance but very delicate especially can make some consumers interested, willing to buy.

In short, the current LED market variety of products, many types of products, the quality is uneven, the price difference is large, the natural price of a good product is high.
