The basic process of discharge discharge of gas discharge lamp is divided into three stages: 1 after the discharge lamp is connected to the working circuit, a stable self-sustaining discharge is generated, and the electrons emitted by the cathode are accelerated by the external electric field, and the electric energy is converted into the kinetic energy of the free electron; 2 the fast moving electron Collision with gas atoms, the gas atoms are excited, and the kinetic energy of the free electrons is converted into the internal energy of the gas atoms. 3 The excited gas atoms return to the ground state from the excited state, and the internal energy obtained is released as optical radiation.
The above process is repeated and the lamp continues to emit light. The light radiation of the discharge lamp is related to the magnitude of the current density, the type of gas, and the level of the gas pressure. Certain types of gas atoms can only radiate spectral lines of certain wavelengths. At low air pressure, the radiation spectrum of the discharge lamp is mainly the characteristic line of the atom. When the air pressure rises, the radiation spectrum of the discharge lamp broadens and develops toward the long wave. When the air pressure is high, there is a strong continuous spectral component in the radiation spectrum of the discharge lamp.
5mm RGB LED is the most popular LED in Through-hole RGB LED.
Same as the 3mm RGB LED, 5mm RGB LED also have three chips in, four pins, common cathode or common anode and those chips can be placed arbitrarily.
The shape of the lens can be 5mm round RGB LED, 5mm Straw hat RGB LED, 5mm pointed top RGB LED and 5mm round LED without flange RGB LED.
For the 5mm RGB LED, the lens can be water clear or diffused. The former has a strong spotlight, and the later lens will make people feels soft.
5mm RGB LED, RGB Dip LED Diode 5mm, 5mm Digital RGB LED, Red Through Hole RGB LED 5mm
