The main classification of LED tubes

LED tubes can also be divided into ordinary monochrome LED tubes, high brightness LED tubes, ultra-high brightness LED tubes, color change LED tubes, flash LED tubes, voltage-controlled LED tubes, infrared LED tubes, negative Resist LED tubes, etc. The LED's control mode has two types constant current and constant pressure. There are a variety of dimming methods, such as simulation dimming and PWM dimming, most of which use constant current control, which can keep the LED current stable, not easy to accept VF changes, can extend the service life of LED luminaires.

Ordinary monochrome LED tube

The ordinary monochrome LED tube has the advantages of small size, low operating voltage, small operating current, uniform lighting, fast response, long life, etc. It belongs to the current control type semiconductor device, and the appropriate current limiting resistor is required in use.

The light-emitting color of the ordinary monochrome LED tube is related to the wavelength of the illuminating, and the wavelength of the illuminating wavelengths also depends on the semiconductor material used to fabricate the LED. The wavelength of the red LED tube is generally 650 to 700 nm. The wavelength of the amber LED tube is generally 630 ~ 650 nm. The wavelength of the orange LED tube is generally 610 to 630 nm, and the wavelength of the yellow LED tube is generally 585 nm, green. The wavelength of the LED tube is generally 555 to 570 nm.

High brightness monochrome LED tube

High-brightness monochrome LED tubes and super high brightness monochrome LED tubes are different from ordinary monochrome LED tubes, so the intensity of the illumination is also different. Typically, high-brightness monochrome LED tubes use materials such as aluminum side (Gaalas), ultra-high brightness monochrome LED tubes, using materials such as gallium arsenide (Gaasinp), and monochromatic LED tubes to use phosphating gallium (GAP) or phosphorus arsenide (Grasp) and other materials.

Coloring LED tube

Changing LED tubes are LED tubes that can change the light color. Color-color LED tube light-emitting color type can be divided into two-color LED tube, three-color LED tube, and multicolor (red, blue, green, white four colors) LED tubes. Changing LED tubes can be divided into two-terminal discoloration LED tubes, three-terminal discoloration LED tubes, and six-terminal discoloration LED tubes and six-terminal discoloration LED tubes.

Flashing LED tube

The flash LED tube (BTS) is a special light-emitting device consisting of a CMOS integrated circuit and an LED tube, which can be used to alarm indication and Undervoltage, overpressure indication. When the flashing LED tube is in use, there is no need to external other components, as long as the appropriate DC operating voltage (5V) is added to both ends thereof, it can flash.

Infrared LED tube

Infrared LED tubes are also referred to as infrared emissions diodes, which can directly convert electrical energy into infrared light (invisible light) and can radiate out of the light-emitting device, which is mainly used in a variety of optical control and remote transmitting circuits. The structure of the infrared LED tube is similar to that of ordinary LED tubes, just different semiconductor materials.

UV LED tube

UV LEDs based on semiconductor materials have advantages such as energy-saving, environmental protection, and long life, have a major application value in the fields of sterilization, medical and biochemical testing. In recent years, semiconductor ultraviolet photoelectric materials and devices have caused more and more attention in the world to become research and development hotspots. On December 12, 2018, the 3rd "International UV-IWUMD 2018" hosted by the semiconductor Institute of the Chinese Academy of Sciences (IWUMD 1 2018) was held in Kunming, Yunnan, with more than 270 representatives from 12 countries. This meeting gathered the latest research and development results of many top experts at home and abroad.

UV LED tube is the main trend of nitride technology development and the development of third-generation semiconductor materials has broad application prospects. To accelerate the development of the third-generation semiconductor solid UV light source, the China science, and technology department is dedicated to the "Third-generation Semicular UV Source Materials and Devices Key Technology" key R & D plan (2016YFB0400800). The support of the National Key R & D Plan and the organizer of the International UV material and device seminars will promote the market-based application of my country's third-generation semiconductor ultraviolet light source, driving my country's UV semiconductor LED tube materials and devices technology to create a relative and industrialization development.
