Are there many varieties of LED lights on mobile phones?

LED is very knowledgeable.

The luminous principle of LED is the same but the structure and packaging, size and power, ever-changing, the LED in N97 belongs to Nokia's customized high-power white LED, it must be a high-end LED designed by a foreign manufacturer, I guess the power should be more than 600 milliwatts. For the specific situation of high-end LEDs, you can refer to the flashlight forum and study the American cree flashlight, which has a power of 3000 milliwatts. (1000 mW LED actual illumination is equivalent to 25 watts of incandescent lamp).

The LED in grandma's small mobile phone is also an ordinary patch white LED, and the power is tens of milliwatts.

The worst thing is the LED in the simple LED flashlight, the garbage white LED produced by the cottage chief, ** yuan.

The backlight of mobile phones is generally 020 (3806), 010 (3804) specifications, of course, many copycats also use 4014, and 3020 models of LED. Different models of lamps have different brightness ranges.

The LEDs used in mobile phones are roughly divided into two categories, in-line LEDs and SMD LEDs. The in-line type is used for auxiliary lighting, and the SMD type can be illuminated, which is more for indication or lighting. SMD LEDs are mostly side-illuminated. In addition, high-power LEDs are rarely used in mobile phones.

There are dozens of types of LED lights for mobile phones, with different sizes, materials, voltages, powers, brightness, uses, etc., and cannot be mixed with each other.

LED lights will have different powers, and each mobile phone manufacturer will have different brightness if the products used are different.
