Analysis of the main causes of LED lamp price difference

The pursuit of high-quality and inexpensive products is the nature of consumers. However, at this stage, it is still more difficult to buy low-quality LED lamps. When we purchase LED lamps, we will find that even if the price difference of the same LED lamp is large, then where is the difference?

Let us talk about LED and energy-saving lamps. In a large shopping mall, a second-tier brand of spiral 20W energy-saving lamps is priced at 59 yuan. Corresponding LED10W downlight prices are between 38 and 120 yuan. Imagine that energy-saving lamps and LED technology, the technical content of the LED is not high, but some of the LED is less than the price of energy-saving lamps, only 38 yuan, really LED costs will drop below the energy-saving lamps, at this stage, it is difficult ; then about 100 yuan LED downlight exactly where it? Mainly chips, drive power, and heat sink materials.

Let's talk about LEDs. A 15W LED downlight, produced by the same manufacturer, has the same appearance, but only one item may have a great price difference; if a 15W LED is made with SMD, and the other is a chip made with high power, then The cost is not the same, of course, the price is not the same, obviously the cost of high-power to do is higher, the price is naturally higher.

Resolve LED lamp price difference main reason Therefore, LED price difference mainly in the following aspects:

Chip: Is the chip genuine or non-genuine? Is that foreign? The top-ranking legions are CREE, OSL, and Nichia in Europe and America; others such as Puri, Toyota Synthetics, Seoul Semiconductor, etc. are also quite good; Taiwan's wafers, New Century, etc. are corresponding to the mid-range, domestic chip prices low.

Packaging: The same good chip is used, whether the package is the original package or its own package? Is it epoxy or silicone? Is it a double gold line or a single line? And so on, these have an impact on prices.

Does the chip use high-power LEDs or SMD light sources? Of course, the power is better. If you use SMD as a light source, then the specifications are 3528 or 5050 or other, etc. Of course, different specifications will not be the same cost, and the price is naturally different.

Is the driving circuit constant voltage or constant current, and if constant current is used, what kind of constant current circuit is used? Stability and reliability, and so on. Some low-end LED luminaires use a low-cost LED driver, and in less than a few months or even a few days, they will flash in the trial. This is caused by poor driving power, of course, these inferior LED luminaires. The price is lower.

Heat dissipation; LED life and heat have a great relationship, heat is not good, light failure is very serious, it will not be long before there will be problems.

Heat-dissipating materials: At present, most of the LED lamps in China are made of aluminum materials for heat dissipation. Therefore, the effect is not the same with die-cast aluminum and aluminum profiles. The cost of the latter is high, and the heat dissipation effect is good.

Appearance process: Needless to say, this point, consumers can see, in particular, need to say that there are some "viscera is very poor", but the appearance of very delicate LED lamps can make some consumers have a good impression, are willing to buy.

In short, the current LED market has a wide range of products, many types of products, uneven quality, large price differences, and high natural product prices.
