LED Chip Components 1W 3030 SMD White Color

Guangmai Technology is professional in making the LED chip components 1W 3030 SMD White color.

1. LED chips components

The light-emitting diode (the name is taken from the initials of "Light Emitting Diode", referred to as LED) is a semiconductor electronic component that can convert electrical energy into light energy. Its electrical symbol is shown in the figure (1) below, with an emissive shape in the figure. Represents the LED, usually the positive (anode) pin is represented by A, and the negative (cathode) pin is represented by K. Electronic components such as light-emitting diodes appeared as early as 1962. In the early days, they could only emit low-luminance red light. Later, other monochromatic versions were developed. Today, the light that can be emitted has spread throughout visible light, infrared and ultraviolet light, and the luminosity has also increased. To a considerable luminosity. At present, light-emitting diodes have been widely used in indoor and outdoor LED lighting, LED displays, traffic lights, automotive lights, TFT LCD display backlights, lighting, optical fiber communications, and so on.

2. Principle of luminescence

Like ordinary diodes, LEDs are composed of a PN junction, and they also have unidirectional conductivity, but LEDs can emit light! As shown in Figure (2), the principle of light emission can be described as: The combination of N (-: negative) type semiconductors with many electrons (negatively charged) and P (+: positive) type semiconductors with many holes (positively charged) to make. When a forward voltage is applied to the semiconductor, electrons and holes will move and recombine at the junction. It is in the process of combining that a large amount of energy is generated, and this energy is released in the form of light. This is the secret of its light . Compared with previous light sources that first convert electrical energy into heat energy and then into light energy (such as the incandescent lamp invented by Edison in the early days), because LEDs can directly convert electrical energy into light energy, they can efficiently convert electrical energy into light energy without wasting light energy. Get light.

3. The structure of LED chip components

Below, we take a common LED white light as an example to illustrate the structure of the LED. As shown in Figure (3), the LED is mainly composed of the following parts:

Chip (function: light source emits light)

Bracket: Including substrate, heat dissipation base, pins, etc. (function: heat dissipation, conduction)

Gold wire (function: conductive)

Transparent resin (function: protect crystal grains, transmit light)
