Classification of LED products

LED Products are many, we simply look at classification. LED light LED according to color, LED features a smooth, light-emitting tube structure, luminous intensity and current, chip material, functions and other standards have different classifications. Following is a brief first six classifications.
1, according to the classification of LED light colors
According to the different LED light colors, can be divided into red, orange, green (and yellow segments, the standard green and pure green), Blu-ray. In addition, some light-emitting diode contains two or three colors of chips. According to a light emitting diode doped or not doped at the scattering agent, colored or colorless, the various colors of light-emitting diodes can be divided into colored and transparent, colorless transparent, colored and colorless scattering four types of scattering.
2, divided by diameter round light φ2mm, φ4.4mm, φ5mm, φ8mm, φ10mm and φ20mm and so on. Abroad, usually recorded as light-emitting diodes φ3mm T-1; to φ5mm's recorded as T-1 (3 / 4); the φ4.4mm's recorded as T-1 (1 / 4). By the size of half-value angle angle can be estimated round luminous intensity distribution. Angle from the luminous intensity distribution to be divided into three categories:
(1) high directivity. Generally pointed epoxy encapsulated, or encapsulated with a metal reflector cavity, without additional scattering agent. Half-value angle of 5 ° ~ 20 °
Or smaller, high directivity, can be used for partial lighting, or light detector associated with the automatic detection system for the composition.
(2) standard. Typically used for light, its half-value angle of 20 ° ~ 45 °.
(3) scattering type. This is the perspective of the larger lights, half-value angle of 45 ° ~ 90 ° or greater, the larger the amount of scattering agents.
3, classified according to the structure of light-emitting diodes: light-emitting diode according to the structure can be divided into full-epoxy, epoxy encapsulated base metal, ceramic and glass base epoxy encapsulated packaging.
T4, luminous intensity and work according to current classification; according to light intensity and operating current can be divided into normal-brightness LED (light intensity <10mcd), high-brightness LED (10 ~ 100mcd) and ultra-high-brightness LED (light intensity> 100mcd). In general LED current to a few dozen mA mA, and low-current LED tube current in the 2mA or less (normal LED brightness and the same).
5: Press the power sub: T a small power LED (0.04-0.08W), the power LED (0.1-0.5W), high-power LED (1-500W), as technology continues to evolve, LED power quest large.
6: According to package sub: T one is the SMD (SMT) and DIP (DIP) in two
For the classification of LED, we have a sense on the line, but also to see the real physical and practical application will be able to truly distinguish us in the will be kind and use of details, please in application of chapter and then the depth of learning and understanding.
