Basic knowledge of SMD LED

The colors of SMD LEDs are red, yellow, green, blue, etc. There are three types of commonly used packages: 0805, 1206, 1210

SMD diodes, also called crystal diodes, are electronic devices that conduct current in one direction.

The characteristics of SMD LEDs: its principle is cold luminescence, and the component life is about 50 to 100 times.

Without warm-up time, the lighting time is about 3 ~ 400ns faster than ordinary lamps. At the same time, it has high electro-optical conversion efficiency and low power consumption;文章配图29

Advantages: low cost, shock resistance, high reliability; small size, low power consumption, light weight, long service life, high brightness, low heat, environmental protection, sturdiness and durability, strong controllability, no shape restrictions, easy to make Various applications.


1. Cleaning: It is forbidden to use unknown chemical liquid to clean the SMD LED, otherwise it will damage the SMD LED. Note: During the cleaning process, immerse the SMD LED in alcohol for less than 1 minute at normal room temperature and use it after natural drying for 15 minutes.

2. Avoid moisture, in order to prevent the product from absorbing moisture during transportation and storage.

3. The storage packaging bag is sealed and stored under the condition that the temperature is <40℃
