Description

A polyhedral infrared and ultraviolet emitting LED night vision camera

technical field

The invention relates to a night vision camera, in particular to a night vision camera with LED as a light source.

Background technique

At present, night vision cameras usually use LEDs as their light sources. The LED light source of a traditional night vision camera is composed of several light-emitting diodes as point light sources. Several light-emitting diodes are arranged in a ring and connected to the circuit board respectively. This light-emitting diode point light source has high energy consumption, short life, low emission angle and Due to the shortcomings of small wavelength and low light output, the night vision camera using this light source has a small detection distance, a relatively narrow detection range, and the captured image is relatively blurred.

The technical solution adopted by the present invention to solve its technical problems is:

A polyhedral infrared and ultraviolet emitting LED night vision camera, comprising a circuit board and a camera lens connected to the circuit board, is characterized in that at least three LED light sources are installed on the circuit board around the camera lens, and the LED light source includes a prism , LED chips are mounted on each side of the prism.

As an improvement to the above-mentioned technical solution of the present invention, each side of the prism is coated with fluorescent powder.

As a further improvement of the above technical solution of the present invention, a lens is installed on the prism.

As a further improvement of the above-mentioned technical solution of the present invention, the prism is installed on a base, and connecting screws are arranged on the base.

There can be four LED light sources above, and the four LED light sources are evenly arranged on the circuit board around the camera lens.

The above-mentioned prisms may be regular hexagonal prisms.

The beneficial effect of the present invention is that: the LED light source adopted in the present invention comprises a prism, and each side of the prism is equipped with an LED chip, which can be 360°infrared monitoring and infrared sensing, and has the advantages of fast response, low energy consumption, long life, emission The angle and wavelength are large, and the characteristics of ultra-high light output. The wavelength is 840-950nm, the receiving and emitting distance can reach 20 meters, and the power can reach 5W. Therefore, the detection distance is small, the detection range is large, and the captured image is clear.
