Description

Tunnel warning lamp

Technical Field

The utility model belongs to the technical field of traffic facilities, a tunnel warning light is related to.

Background

The traffic tunnel is a channel dug in an existing building or an earth-rock structure, and is an engineering building buried in the ground. Because the light is dim in the traffic tunnel, in order to improve the light in the traffic tunnel, all install the tunnel lamp in most tunnels, traditional tunnel lamp all is often bright in the tunnel to light in the tunnel is comparatively dim relatively, makes the driver of back car hardly judge the vehicle distance of back car and front car, consequently causes the traffic accident of knocking into the back in the tunnel frequently.

For example, the current chinese patent network discloses an infrared induction LED tunnel lamp [ grant publication No.: CN204005660U j comprises a lamp housing, an LED light source panel located inside the lamp housing, a driving power supply electrically connected with the LED light source panel, a control chip electrically connected with the driving power supply, and an infrared reflection sensor electrically connected with the control chip. When the LED tunnel lamp is used, a plurality of LED tunnel lamps are sequentially installed on the side wall in the tunnel along the length direction of the tunnel, the LED light source panel faces the road surface and sends infrared light through the infrared reflection sensor, when no vehicle passes through the tunnel, the LED light source panel does not emit light, when the vehicle passes through the tunnel, the infrared light reflected back by an object is received, then the control chip connected with the control chip is triggered, the LED light source panel is controlled to be lightened, the tunnel is illuminated, and the road condition in the tunnel can be seen clearly by the vehicle.

The infrared induction LED tunnel lamp has the following defects in use: 1. when a vehicle passes by, the infrared reflection sensor needs a certain time to receive infrared light reflected by an object, the speed of the vehicle on a highway is high, and an LED tunnel lamp cannot be lightened timely, so that the function of illumination cannot be achieved; 2. the LED light source is lighted when the vehicle passes through, and the change of on-off of the LED light source can be observed by the vehicle at the rear part, because the LED light source panel faces the road surface, the LED light source panel mainly plays a role of illumination, and the change of on-off of the LED light source is not direct and striking enough for the rear vehicle, so that the warning effect for the rear vehicle is limited.

Disclosure of Invention

The utility model aims at having the above-mentioned problem to current technique, provided a tunnel warning light, the utility model aims to solve the technical problem that: how to improve the warning effect to the vehicle when the response timeliness of tunnel lamp improves.

The purpose of the utility model can be realized by the following technical proposal:

the utility model provides a tunnel warning light, includes lamp body, sets up lamp pearl and the control circuit board of setting in the lamp body on the lamp body, the lamp pearl is connected with the control circuit board electricity, a serial communication port, the through-hole has been seted up on the leading flank of lamp body, and this warning light is still including setting up infrared emitter and the infrared receiver in the lamp body, infrared emitter and infrared receiver all are connected with the control circuit board electricity, infrared emitter and infrared receiver all transmit signal or received signal through the through-hole.
