1. The difference in luminous intensity of general, medium, and high-brightness of each manufacturer depends on the brand and quality of the light-emitting chip. Due to the late start of domestic light-emitting chip companies, there is still a gap with foreign mature light-emitting chip products in terms of light intensity, light display, color reproduction, color vividness, color temperature, etc., and the difference in price is also very large. .
2. The size of the chip. If the manufacturer wants to achieve higher luminous intensity, it must increase the size of the light-emitting chip. Therefore, the higher the luminous intensity, the greater the power and the larger the size of the light-emitting chip. .
3. Power and voltage. Power and voltage are also a major factor affecting brightness. Many times the customer's use environment has requirements for voltage or current, so our sales staff also ask about the power and voltage at the first time when communicating with customers. Is there any requirement for current, depending on the color and type, the lowest voltage can be 1.8V and the highest 3.6V. The current is 30MA/6OMA/15OMA because of the difference in power, and the corresponding power is 0.1W/0.2W/0.5W.
To sum up; in fact, the difference between 2835 patch white light, medium light and high light is the luminous intensity, and the factors that affect the luminous intensity are the points we analyzed above, and it is precisely because of these factors. As a result, their prices vary greatly.
