LED decorative lights are rich in color, small in size and durable, and are therefore widely applicable for decorative purposes. LED decorative lights can be divided into many kinds
1, according to the structure of LED
According to the structure of LED, there are all kinds of epoxy encapsulation, metal base, epoxy packaging, ceramic base, epoxy packaging and glass packaging structure.
2, according to luminous intensity and working current
According to the luminous intensity and operating current, there is a general brightness of LED (luminous intensity 100mcd); the luminous intensity between 10 ~ 100mcd is called a high brightness led. Generally, the working current of LED is over ten mA to tens of mA, while the working current of low current LED is below 2mA (brightness is the same as that of ordinary light emitting diode).
In addition to the above classification methods, there are also classification according to the chip materials and classification by function.
3, according to the light emitting tube color points
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. A scattering led and used as an indicator.
4, according to the luminous tube characteristics of the smooth surface
According to the luminous characteristics of the luminous tube, the dividing lamp, the square lamp, the rectangular surface, the luminous tube, the lateral tube, the surface mounting micro tube, etc..
