1. According to the luminous tube luminous color of solar sensor security light

According to the light emitting tube color, can be divided into red, orange, green (and subdivided yellow green, standard green and purecraftsman portable work light - Hommiiee green), blue light, etc.. In addition, some leds contain chips in two or three colors.

According to the light emitting diode with or without scattering agent, color or colorless, the above various colors of light-emitting diode can also be divided into colored transparent, colorless transparent, colored scattering and colorless scattering four types. Scattered-type light-emitting diodes are used as indicators.

2. According to the luminous tube surface characteristics of solar sensor security light

According to the characteristics of light emitting tube, it can be divided into round lamp, square lamp, rectangular lamp, surface light emitting tube, lateral tube, micro-tube for surface installation, etc. According to the diameter of the circular lamp is divided into φ2mm, φ4.4mm, φ5mm, φ8mm, φ10mm and φ20mm. Foreign countries usually put φ3mm light-emitting diode as T-1; Write the 5mm as t-1 (3/4); Let's call the φ4.4mm t-1 (1/4).

The angular distribution of circular luminescence intensity can be estimated by the size of half-value Angle.

There are three types of luminescence intensity Angle distribution:

(1) High directivity. Generally, it is a pointed epoxy package, or a metal reflecting cavity package, and no scatterer. The half-value Angle is 5° ~ 20° or smaller, with high directivity, can be used as local lighting source, or combined with light detector to form an automatic detection system.

(2) Standard type. Usually used as an indicator, its half-value Angle is 20° ~ 45°.

(3) Scattering type. This is a large Angle of view indicator light, half value Angle of 45° ~ 90° or more, the amount of scatterer is large.

3. According to the structure of light-emitting diode points of solar sensor security light

According to the structure of the led, it can be divided into epoxy packaging, metal base epoxy packaging, ceramic base epoxy packaging and glass packaging structure.

4. According to the luminous intensity and working current points of solar sensor security light

According to the luminous intensity and working current, there are ordinary brightness LED (luminous intensity 100mcD); The luminescence intensity between 10 ~ 100mcd is called high brightness leds. General LED operating current in the tens of mA to dozens of mA, and low current LED operating current in less than 2mA (brightness and the same as ordinary light emitting tube).

In addition to the above classification methods, there are also methods of chip material classification and function classification.
