What are the categories of LED products?

Answer:

According to the luminous color of the luminous tube, it can be divided into red, orange, green (subdivided green yellow, standard green and pure green), blue light and so on. In addition, some LEDs contain chips of two or three colors. The light emitting diodes can be divided into four types: colored transparent, colorless transparent, colored scattering and colorless scattering, according to the light emitting diode with or without scattering agent, colored or colorless. The scattering LED is suitable for use as an indicator.
According to the characteristics of the luminous surface of the luminous tube, the divided circle lamp, square lamp, rectangle and surface luminous tube, lateral tube, surface mounting micro tube, etc.. The circular lamp is divided into diameter 2mm, Phi 4.4mm, Phi 5mm, Phi 8mm, Phi 10mm and phi 20mm by diameter. Abroad, 3mm 1/4 is usually labeled as "T-1", and "5mm" is denoted as "T-1" (3/4), and "4.4mm" is denoted as "T-1". The intensity distribution of circular luminous intensity can be estimated by the half value angle.
(1) high directivity. Typically a pointed epoxy package, or a metal reflective cavity package with no scattering agent. The half value angle is 5 degrees to 20 degrees or less, and has high directivity, which can be used as a local illumination light source or combined with an optical detector to form an automatic detection system.(2) standard type. Usually used as an indicator lamp, with a half value angle of 20 degrees to 45 degrees.(3) scattering type. This is an indicator light with larger viewing angle, and the half value angle is 45 degrees to 90 degrees or more, and the amount of the scattering agent is larger.
