Each manufacturer may also have certain errors due to different test instruments, and the imported chips used by some manufacturers are brighter than some manufacturers' high-brightness models even if they are Puliang. This has caused a lot of errors, and there is no uniform standard. Taking our company as an example, the luminous intensity of the general brightness model is 20-22lm, the medium brightness model is 22-24m, and the high brightness model is 24-26lm.
Factors affecting brightness: 1. The luminous intensity of each manufacturer's general, medium, and high-brightness is different mainly depending 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. 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 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/60MA/150MA because of the different power, and the corresponding power is 0.1W/0.2W/0.5W.
