LED Classification


    1, according to the color LED light-emitting sub -
    LED light colors according to points, can be divided into red, orange, green (also broken down yellow, and green, the standard green and pure green), Blu-ray Disc. In addition, some contain two kinds of light-emitting diodes, or three kinds of color chips.
    According to a light-emitting diode doped or not doped at scattering agent, colored or colorless, the various colors of light-emitting diodes can also be divided into colored transparent, colorless transparent, colored and colorless scattering four types of scattering. Scattering-type light-emitting diodes and light up with being used.
    2, according to LED features a smooth sub -
    By LED features a glossy cyclotomic lights, side lights, rectangular, surface light-emitting tube, lateral pipe, surface-mount using a micro-pipe. Round Light by diameter into φ2mm, φ4.4mm, φ5mm, φ8mm, φ10mm and φ20mm so. Foreign usually φ3mm light-emitting diodes denoted by T-1; to φ5mm's recorded as T-1 (3 / 4); the φ4.4mm's recorded as T-1 (1 / 4).
    Half-value angle can be estimated from the size of a circular angular distribution of luminous intensity. From the luminous intensity distribution angle to be divided into three categories:
    (1) high directivity. Generally pointed epoxy encapsulated, or packaged with a metal reflector cavity and does not increase scattering agent. Half-value angle of 5 ° ~ 20 ° or less, with a high directivity can be used for partial lighting use, or in conjunction with the optical detector which is part of automatic detection system.
    (2) standard. Is usually used for light, its half-value angle of 20 ° ~ 45 °.
    (3) The scattering type. This is the perspective of the larger lights, half-value angle of 45 ° ~ 90 ° or more, a larger amount of scattering agents.
    3, according to the structure of sub-light-emitting diode
    The structure of the light-emitting diode according to a full-epoxy encapsulation, metal base epoxy encapsulation, ceramic base and glass epoxy encapsulated package structure.
    4, according to light intensity and operating current sub -
    According to light intensity and operating current divided into general brightness of the LED (light intensity <10mcd); ultra-high brightness of the LED (light intensity> 100mcd); the luminous intensity of 10 ~ 100mcd inter-called high-brightness light-emitting diodes.
    LED's work in general mA current in a dozen to a few mA, and low-current LED operating current in the 2mA below (normal LED brightness and the same).
    In addition to these classifications, there are also classified according to chip materials, and by functional classification method

chongqing tianli lamp co., ltd., is a company which is selling motorcycle turn light product.
