Description

An environmental monitoring and supplementary light device

technical field

The utility model relates to the technical field of traffic light supplement equipment, in particular to an environmental protection monitoring light supplement device.

Background technique

At present, the commonly used flash for traffic monitoring and photographing, its light source is a full-spectrum light source, that is, it contains visible light and invisible light. Traffic surveillance photography generally uses the visible light part of the flash.

As shown in FIG. 1 , an existing flasher includes a lamp socket 1 and a light source 2 installed in the lamp socket 1 , and a lampshade 6 is installed at the opening of the lamp socket 1 . The flash function is realized through the light emission of the light source, which assists in monitoring and taking pictures.

The above technical solutions have the following defects: the light emitted by the light source is visible light, and the visible light flashes are relatively dazzling. In the case of sufficient natural light during the day, the degree of impact on the human eye is not obvious, and there is no natural light at night or insufficient natural light during the day. Under these circumstances, the degree of impact on the human eye is obvious, which will cause the driver of the vehicle to drive unsafely.

Utility model content

In view of the deficiencies in the prior art, the purpose of the present invention is to provide an environmental monitoring and supplementary light device, which can reduce the intensity of light, thereby reducing the degree of influence on the human eye and improving the safety factor of the driver.

Through the setting of the first limit edge and the second limit edge, the rotation range of the filter plate is limited, so that during the rotation process of the motor-driven filter plate, even if the motor rotation error, it can be limited by the first limit edge and the second limit edge. The edge is blocked to avoid over-rotation, thereby reducing the probability of light leakage.

In a preferred example of the present invention, the first limiting edge and the second limiting edge are both made of rubber.

By adopting the above technical solution, if the motor rotates excessively, the first limit edge and the second limit edge will collide, which will affect the structural stability and sealing performance of the lamp itself. Through the arrangement of the first limiting edge and the second limiting edge made of rubber, the two have a buffering effect when they collide, and the vibration is small, thereby reducing the impact on the lamp itself.

In a preferred example of the present invention, an annular groove is formed on the inner side wall of the filter cover, and the edge portion of the filter plate moves in the annular groove.

By adopting the above technical solution, since the filter plate is not connected to the output shaft of the motor, the filter sheet is suspended in the air at one end away from the motor, and the fitting degree with the filter cover is not high, which is prone to light leakage. Through the arrangement of the annular groove, the position of the filter page of the filter plate is limited, thereby improving the fit between the filter plate and the filter cover, thereby reducing the probability of light leakage.

In a preferred example of the present invention, it can be further configured that the side wall of the filter cover is provided with a concave portion, the outer side wall of the filter cover is provided with a snap ring, and the lamp holder is provided with a The snap ring is fitted with an engaging groove, the snap ring is provided with a mounting bolt connected with the lamp socket, and the mounting bolt is partially located in the recessed portion.

By adopting the above technical solution, the fitting of the snap groove and the snap ring improves the connection integrity of the lamp holder and the filter cover, the relative position of the two is not easily changed, and the stability after installation is improved; And the arrangement of the recess provides sufficient space for the mounting bolts.

In a preferred example of the present invention, it can be further configured that the lamp holder is provided with a heat sink.

By adopting the above technical solution, the heat sink can be in contact with the air or rainwater to take away the heat generated when emitting light, so as to achieve the purpose of improving the heat dissipation effect.

To sum up, the present utility model includes at least one of the following beneficial technical effects:

1. Drive the filter plate to cover the through hole through the drive assembly, so that the visible light can be illuminated through the filter plate or filter cover, so that the light intensity is reduced, thereby reducing the impact on the human eye and improving the driver's driving safety factor;

2. Through the setting of the first limit edge and the second limit edge, the rotation range of the filter plate is limited, so that during the rotation process of the motor-driven filter plate, even if the motor rotation error, it can be affected by the first limit edge and the second limit edge. The two limit edges are blocked to avoid excessive rotation, thereby reducing the probability of light leakage;

3. Through the setting of the heat sink, it can be in contact with air or rainwater to take away the heat generated when emitting light, so as to achieve the purpose of improving the heat dissipation effect.
