Abstract

The invention provides a method for improving the permeability of white light supplementary lighting, which comprises the steps of designing light paths of a white light lamp, and supplementing lighting through combination of two or more groups of light paths to enable the light to avoid the area right in front of a lens; the method for improving the permeability of the white light supplement light does not change the appearance of the existing product, is not limited by the environment, is not influenced even if dust exists in the environment, can improve the supplement light intensity, and ensures that the supplement light is more uniform.

Description

Method for improving transmittance of white light supplementary lighting

Technical Field

The invention belongs to the field of security monitoring cameras, and particularly relates to a method for improving the transparency of white light supplementary lighting.

Background

The traditional light supplement scheme is as follows: when the white light lamp performs light supplement at night, dust particles and water vapor in the air can reflect or scatter light rays to enter the lens, so that an image observed in the lens is blurred, and in the serious condition, the camera cannot see a monitoring scene and objects clearly.

The existing optimization scheme is as follows: the light supplement lamp is far away from the lens, and light reflection in front of the lens is weakened. The disadvantages are as follows: 1. this problem cannot be solved completely; 2. the distance between the light supplement lamp and the lens is far, the whole volume of the camera is enlarged, and the appearance is not attractive enough.

Disclosure of Invention

In view of the above, the present invention provides a method for improving the transmittance of white light supplement to overcome the above-mentioned defects in the prior art.

In order to achieve the purpose, the technical scheme of the invention is realized as follows:

Designing light paths of a white light lamp, and supplementing light through combination of two or more groups of light paths to enable light rays to avoid a region right in front of a lens;

Further, the method for avoiding the light from the area right in front of the lens comprises the following steps: an irregular lens is used to deflect the optical path.

Compared with the prior art, the invention has the following advantages:

By using the light supplementing scheme, the purposes of avoiding the area in front of the lens and supplementing light to the whole environment can be achieved. Has the following advantages: 1. the appearance of the existing product is not changed, 2, the product is not limited by the environment, and even if dust exists in the environment, the product is not affected. 3. The light supplement intensity can be improved, and the light supplement is more uniform.

Finally, on the premise of not influencing the appearance, the permeability of the camera under the condition of white light supplement is greatly improved, and the environmental adaptability and the imaging quality of the monitoring camera are improved.
