Description

A red and green laser light prompt system

technical field

The utility model relates to a prompting device related to a red and green laser lamp prompting system, in particular to a red and green laser lamp prompting system for pedestrian crossings.

Background technique

On rainy and foggy days or at night on the sidewalk under the traffic lights at some intersections, because of the dark light, the traffic lights are not very clear and obvious, and pedestrians are walking on thin ice when crossing the road. Most vehicles can slow down and wait when passing by, but some vehicles pass by at high speed because they do not pay attention to traffic lights when passing, which causes many traffic accidents, causing huge casualties and property losses.

Utility model content

The purpose of this utility model is to provide a red and green laser light prompting system for the above shortcomings. For the situation of insufficient light at night or in cloudy, rainy and hazy days, a red and green laser light prompting system is installed at each intersection where traffic lights are installed. , activated by an optical switch. Convenient and practical, effectively reducing the probability of traffic accidents.

A red and green laser light prompting system is realized by adopting the following technical solutions: a red and green laser light prompting system includes a laser generator and a light control switch, the laser generator adopts a red laser light and a green laser light, and the red laser light Including the red laser light of the stop line and the red laser light of the zebra crossing, the green laser light includes the green laser light of the stop line and the green laser light of the zebra crossing, the red laser light of the stop line and the green laser light of the stop line are installed at both ends of the car stop line approaching the intersection The zebra crossing red laser light and the zebra crossing green laser light are installed at both ends of the zebra crossing near the crossing; the light control switch includes a first light control switch and a second light control switch; the zebra crossing green laser light, the red laser light of the stop line and the traffic red light The lights are connected in parallel with each other, a first light control switch is arranged between the traffic red light and the zebra crossing green laser light, and the first traffic control switch is arranged before the traffic red light; the zebra crossing red laser light, the stop line green laser light and the traffic green light are mutually In parallel connection, a second light control switch is provided between the traffic green light and the red laser light of the zebra crossing, and a second traffic control switch is provided in front of the traffic green light; the red and green laser light prompt system shares the power supply with the traffic traffic light.

When the first traffic control switch that controls the traffic red light inside the traffic light system is closed, the traffic red light is on. If the outdoor light is sufficient at this time, the first light control switch is turned off, and the red and green laser light prompt system is not activated; if at this time If the outdoor light is insufficient, the first light control will be turned on and off, and the red and green laser light prompt system will be activated. The green laser lights at both ends of the zebra crossing will light up and radiate to 50cm from both ends of the zebra crossing to remind pedestrians that they can pass the intersection at this time; The red laser light of the stop line at the stop line lights up to remind the driver to stop and wait;

When the second traffic control switch that controls the traffic green light inside the traffic light system is closed, the traffic green light is on. If the outdoor light is sufficient at this time, the second light control switch is turned off, and the red and green laser light prompt system is not activated; If it is not enough, the second light control will be turned on and off, and the red and green laser light prompt system will be activated. The red laser lights located at both ends of the zebra crossing will light up and radiate to 50cm from both ends of the zebra crossing, reminding pedestrians that the intersection is prohibited at this time; at the same time, it is located at the car stop line The green laser light of the stop line lights up to remind drivers that they can pass through the intersection.

The first light control switch and the second light control switch are commercially available AS-10 light control automatic switches.

The laser generator can use 8W-30WRGB color laser lights, the laser lights at the zebra crossings use 8wRGB color laser lights, and the laser lights at the car parking lines use 30wRGB color laser lights. 8wRGB color laser light, the radiation distance is short, which effectively avoids the driver's misunderstanding caused by the beam reaching the roadway. The 30wRGB color laser light has a long radiation distance, and the beam reaches the entire road parking line, reminding the driver to stop and wait in an all-round way.

The laser generator is synchronized with the corresponding traffic lights, that is, when the traffic lights flash, the corresponding laser lights will also flash, reminding drivers to slow down and pedestrians to wait to pass the intersection.

The red and green laser light prompting system of the utility model utilizes the non-divergence of the light of the laser light to attract the eyes of people as far as several kilometers away. Due to the use of the light control switch, the red and green laser light system is turned on in rainy, hazy days or at night, and the red and green laser light system will not be turned on when the light is sufficient, and the working status of the system is controlled by the light control switch. Effectively avoid energy waste, environmental protection and energy saving. The red laser light for the stop line, the green laser light for the stop line, the red laser light for the zebra crossing, and the green laser light for the zebra crossing are respectively installed beside the car parking lane and the pedestrian zebra crossing. , effectively avoiding the confusion of the driver's vision caused by the laser beam hitting the car driving on the road.
