LED lamp as a kind of green lighting apparatus, is more and more widely used in lighting, decoration, stage lighting and other fields. As manufacturers of low barriers to entry, mostly for CKD, detection equipment, means are lacking, the standard is not unified, makes the market LED lighting products uneven, some good and some bad, but due to intense competition, price war as one falls, appearance, structure, function is almost the same as the product, price difference is 2-3 times, makes many user temporarily cannot read.
" A penny ", everybody knows that no good goods cheaper, but still do not spread from why and come. This not only makes the general production of LED led LED lamps dealers feel difficult to distinguish, and consumers.
This article is to introduce LED lamps nine factors price decision.
①wavelength
Wavelength is determined object emitting color physical quantity. Wavelength consistent with the LED luminous tube, the lamp emits light color consistency, the so-called good colour purity. A lamp is composed of a plurality of LED light emitting tube, selected wavelength consistent LED tube, the cost will be increased. And relax the requirement, most users do not understand the pure color lamps index decreasing production cost down, of course, can sell for a lower price. Other requirements such as color, no LED by-minute color is difficult for LED LED screen, buy by-minute color and will increase the cost of production.
② LED chip
LED luminous body for the chip, the chip is different, price difference is very great. Now on the market are Japan, the United States of America common chip as well as the Taiwan and Chinese native land manufacturer LED chip. As a result of day, beautiful chip is more expensive, price nature is higher than Taiwan and the mainland of the LED chip, so the lamp of higher price. As to how to determine which type of LED chip is used, only the manufacturer truthfully inform or on luminous tube observation or detection.
③brightness
LED lighting luminance differences, different prices. But the decision to lamp luminance is still the tube core quality and the size of power, from the cost, the tube core high luminous efficiency, more than 100 lumens per watt of power greater than 3 watts, its price is significantly higher than the other performance specifications.
The chip size
The size of the chip to length, large chip LED quality than the small chip. Chip, means that the tube core base, good heat dissipation effect, bear power, can provide large flux. The price with the chip size is proportional.
The leakage current
LED is a light emitting diodes, diode having unidirectional conductivity, but also the existence of reverse current, it is called leakage, leakage current of LED, pipe consumption, so a shorter life expectancy, the price of natural low.
The antistatic ability
Antistatic ability is diode reverse voltage withstand capabilities. If the antistatic ability is poor, easy breakdown luminous tube. The antistatic ability of the LED luminous tube, long service life, its quality is stable, so the price is high. Usually antistatic greater than 700V LED can be used in LED lighting.
The life
Lighting quality is the key to life. A measure of life indicator is a light to the initial brightness of a few percent, not on time. General working current is bigger, its decay faster, the shorter the life. Of course, life is long, the price is high.
⑧emitting angle
The use of different LED light emitting angles are not the same. Special lighting angle, higher prices. Such as the diffusion angle, higher prices.
In colloid
The ordinary LED lamps colloidal for epoxy resin, with UV resistant and fire retardant LED is more expensive, high-quality outdoor LED lighting, should be UV resistant and fireproof, the price is not cheap.
Through the above analysis, we should know that LED lighting market is a bit confusing market. The popularization and application of LED lamps to bring negative effect. We see decision LED lamps in the prices of nine aspects, we should carefully identify, compare, buy the stable quality, good reputation of the enterprise products, do not buy low price unusual product. Because there is no free lunch
