The RGB LED Light Tube is a common light emitting device that emits energy through recombination of electrons and holes. It is widely used in the field of lighting. With the continuous development of the technology, the RGB LED Light Tube has been widely used in displays and lighting.
What are the features of RGB LED Light Tube?
What is the light emission principle of RGB LED Light Tube?
What are the advantages of RGB LED Light Tubes over white LEDs?
1. Voltage adjustable. Conventional 80-245-V fluorescent lamps are illuminated by the high voltage released by the rectifier and cannot be switched on when the voltage is reduced. The RGB LED Light Tube can glow within a certain voltage range and the brightness can be adjusted.
2. Save energy, longer service life. The power consumption of RGB LED Light Tubes is less than a third of the power consumption of conventional fluorescent lamps, and the service life is also ten times that of conventional fluorescent lamps. It can be used for a long time without replacement, reducing labor costs. It is more suitable for occasions that are difficult to replace.
3. Robust and reliable, long-term use. RGB LED Light Tube itself uses epoxy resin instead of conventional glass, which is more robust and reliable. Even if hit to the ground, the LED will not be easily damaged and can be used with confidence.
The terminal voltage of the PN transition of the RGB LED Light Tube forms a certain potential barrier. When the preload is applied in the forward direction, the potential barrier falls and the majority carriers in the P-region and the N-region diffuse to each other. Since the electron mobility is much greater than the hole mobility, a large number of electrons diffuse into the P-range, which represents the injection of minority charge carriers into the P-range. These electrons recombine with holes in the valence band, and the energy obtained during recombination is released in the form of light energy. This is the principle of PN transition light emission.
The attenuation problem of RGB LED tubes and the effects of UV rays on the human body are difficult to solve in the short term, so although both can meet the white light requirements, there are different results. In terms of applications, RGB is obviously more diverse than white LEDs, such as car lights, traffic signs, shop windows, etc. If a certain light band is required, the color mixing of RGB LED Light Tube can be done at will. It is more detrimental, so naturally stronger in effect. White LEDs are significantly inferior in terms of clarity and color purity RGB LED Light Tubes. In addition, the problem of light attenuation and the high wafer cost make RGB LED Light Tubes more advantageous.
