Production to industrial application, LED all kinds of classification
Date: Publisher:

LED light-emitting diode, is a solid-state semiconductor devices, it can be directly put DianZhuan into light. The heart of the LED is a semiconductor chip, when a current flows through a wire to the chip, electrons and holes will be into the quantum well, electron and holes compound within the quantum well, then will be issued in the form of photon energy. According to the different forms, the classification of the LED is varied, the more the main is classified according to the following four forms.

  1. According to the luminous tube emitting light colors

According to the luminous tube light color points, can be divided into red, orange, green, yellow green, standards, green and subdivision and pure green), blue, etc. In addition, some leds included in two or three kinds of color chip.

According to the light emitting diode out light scattering or after adding the agent, colored or colorless, the above all sorts of color of leds can also be divided into colored transparent, colorless, transparent, colored and colorless scattering four types. Scattering of light emitting diode and up to do light is used.

  1. According to the luminous tube out smooth feature points

According to the luminous tube smooth feature points out round lights, side lights, rectangular, LED panel light surface light-emitting tube, lateral tube, install with the micro tube surface, etc. Circular lamp according to the diameter from 2 mm, 4.4 mm, and phi phi 5 mm to 8 mm, from 10 mm and 20 mm. Foreign usually write phi 3 mm leds for T - 1; Write phi 5 mm T - 1 (3/4); Write phi 4.4 mm T - 1 (1/4).

Can be estimated by half value Angle size round Angle of luminous intensity distribution. From the Angle of luminous intensity distribution of three points:

(1). High directivity is commonly pointed epoxy encapsulation, or with metal reflective cavity encapsulation, and do not add scattering agent. Half value Angle of 5 ° ~ 20 ° or less, has the very high directivity, can be used for local lighting light source, or with light detector combined to form an automatic test system.

(2) standard. Often used as indicator light, the half value Angle of 20 ° to 45 °.

Type (3) scattering. This is a bigger light Angle, half value Angle is 45 ° ~ 90 ° or greater, the amount of scattering agent is bigger.

  1. According to the structure of light emitting diode

According to the structure of the light-emitting diodes (leds) have all epoxy coating, metal base epoxy encapsulation, ceramic base epoxy encapsulation, glass encapsulation structure, etc.

  1. According to the luminous intensity and working current

According to the luminous intensity and working current are normal brightness LED luminescence intensity (< 10 MCD); High brightness LED (light emitting intensity > 100 MCD); The luminous intensity between 10 to 100 MCD called high brightness leds. General LED the work of the current in a dozen mA to dozens of mA, and LED the working current of low current under 2 mA brightness (the same as the ordinary light-emitting tube)

Above is the four common LED classification, each application to LED as raw materials for the production of the enterprise or factory may use different classification methods.
