LED infrared fill light features

1. LED infrared fill light can be fixedly used, and the infrared fill light also has the characteristics of daytime and daylight superimposed use and nighttime independent use of license plate illumination. It can suppress the backlight during the day and suppress the headlight glare at night.

2. Make the camera have better wide dynamics.

3. The directionality of the light angle is good, the light pollution is extremely small, and there is almost no stimulation to the human eye, which does not affect the safety of driving.

4. The spot of the LED infrared fill light is uniform, and the luminous intensity and the light exit angle can be adjusted.

5, LED infrared fill light installation and debugging is convenient, can be matched with a variety of CCD cameras.

6, LED monitoring fill light power consumption is low, high efficiency.

7, LED monitoring fill light can be bright day and night, long service life, LED light source life is 50,000 hours.

8, small power consumption, light weight, small size, easy to install, you can easily form a bayonet integrated device with the camera and protective cover.


The core of LED infrared fill light:

The core part of the LED infrared fill light is a light-emitting chip composed of a P-type semiconductor and an N-type semiconductor, and a forward voltage is applied to the PN junction of the LED. When a forward current is applied to the LED chip through the wire, the electron is pushed. To the P-type semiconductor region, electrons are combined with holes in the P region, and then energy is emitted in the form of photons, which is the principle of LED illumination. It can convert electric energy directly into light energy, which belongs to cold light source, also called semiconductor solid state light source.

LED infrared fill light is generally used to improve the light on the front of the object to use a complementary method. This kind of fill light is generally made of high-brightness light-emitting diode (LED), which has the characteristics of stable operation, low heat generation, low energy consumption and long service life! As for the parameters, they are generally not clearly marked in such products.

The so-called LED infrared fill light is a special lighting equipment that projects a specific light to the object to be illuminated, directly or indirectly to obtain the light.

When used to promote plant photosynthesis, it is directly obtained by light; when used to improve the ambient illumination and improve the low illumination of the camera, it is a scene to be photographed by a specific light illumination, so that the camera can capture a good quality picture. Indirectly get light to make up.

The LED infrared fill light source usually has LED, metal halide lamp, fluorescent lamp, high pressure sodium, incandescent lamp, iodine tungsten lamp, xenon lamp (HID) and the like.
