Factors affecting the cost of lamp beads

1. Cost of spectroscopic

Wavelength is the physical quantity that determines the color of an object's light. Wavelength consistent LED luminous tube, its luminaire emits light of the same color, that is, the so-called color pure good. A lamp is composed of multiple LED light-emitting tubes. The cost will increase if selected LED tubes with the same wavelength. And relax the requirement, THE COLOR PURE INDEX THAT MOST USER DOES NOT UNDERSTAND LAMPS AND LANTERNS DROPS, PRODUCTION COST ALSO CAME down, OF COURSE, CAN SELL LOWER PRICE. In addition, if the color is consistent, it is difficult to screen the LED tube without an LED spectrometer, and the purchase of a spectrometer will increase the production cost.

2. LED chip price

LED luminous body for the chip, different chip, the price difference is very big. Now the market is commonly seen in Japan, the United States, and Taiwan, and among China's local manufacturers of LED chips. As the fragments of Japan and the United States are more expensive, the price is naturally higher than the LED chips of Taiwan and the mainland, so the price of its lamps and lanterns is higher. As for how to judge what kind of LED chip is used, only the manufacturer truthfully informs or observes, or tests its light tube.

3. Luminance lumen value

LED lamps vary in brightness and price. But the luminance is still determined by the quality of the core and the size of the power, from the cost, the luminous core efficiency is high, more than 100 lumens per watt, and the power is greater than 3 watts of its price is higher than other performance specifications.

4. The chip size

The size of the chip is expressed by the side length, and the quality of the big chip LED is better than that of the small chip. The large chip means that the core matrix is large, the heat dissipation effect is good, the power is large, and the light flux can be provided. The price is proportional to the size of the chip.
