Fluorescent powder refers to substances that can absorb energy and then emit visible light through energy conversion. The quality of general fluorescent powder determines the luminous efficiency and color of the finished product. It can be classified by color, such as yellow pink, red pink, green pink, orange pink, yel……

Color temperature: The color of the absolute blackbody changes with temperature. If the color of the light source's emission is exactly the same as that of the absolute blackbody at a certain temperature, the temperature is called the color temperatur

Current: The amount of electricity passing through any cross-section of a conductor per unit of time, expressed in I, in amperes (A). Among them, IF is the forward current, IR is the reverse current, and IFp is the maximum forward current. Volt

The characteristic of the current flowing through the PN junction of a chip changing with the voltage applied to both ends of the PN junction. LED has unidirectional conductivity and nonlinear characteristics. The voltage at

The light of LEDs is generated by the recombination of electrons and holes When a forward voltage is applied to both ends of the LED, and current flows from the LED anode to the cathode, the minority and majority carriers in the semiconductor recom

LED, also known as light-emitting diode, is a solid-state electroluminescent semiconductor device that converts electrical energy into light energy.
