Novel traffic signal lamp

Abstract

The invention discloses a novel traffic signal lamp, and solves the problems of the poor prompting effect for the red-green achromatopsia or anomalous trichromatism pedestrians, the maintenance difficulty and burnout of the LED lamp beads in case of excessively high power voltage in the prior art. The novel traffic signal lamp comprises a pedestal, a square column and a function board. The function board is provided with a light shading board, a time display board, a green indicating lamp and a red indicating lamp. The time display board, the green indicating lamp and the red indicating lamp are respectively provided with an ABS transparent plastic cover. The function board is provided with a go indicating board and a stop indicating board. The green indicating lamp and the red indicating lamp respectively comprise an aluminum substrate, a power wire, a pressing board and LED lamp beads having two power pins. Multiple light transmitting through holes are evenly distributed on the pressing board. The light transmitting through holes are provided with pin slots. The power wire is provided with a resistance-capacitance step-down circuit. The novel traffic signal lamp is simple in structure, scientific and reasonable in design and convenient to maintain so that the prompting effect for the red-green achromatopsia or anomalous trichromatism pedestrians can be greatly enhanced and burnout of the LED lamp beads is not liable to occur in case of excessively high power voltage.

Description

technical field [0001] The invention relates to a novel traffic signal lamp. Background technique [0002] Traffic lights are essential equipment for traffic command, which brings great benefits to people's safety and smooth roads. Now the traffic lights on pedestrian crossings are all traffic lights. For people with red-green color blindness and color weakness, it is difficult to distinguish traffic. The order has brought unsafe factors to this group of people crossing the road, and also caused great potential danger to this group of people crossing the road, bringing unnecessary troubles to normal traffic operations. [0003] LED lights are widely used in traffic lights due to their advantages of energy saving, environmental protection, high brightness and long service life. The electrical connection between the LED lamp beads in the existing traffic signal lights and the conductor on the aluminum substrate is usually realized by welding, which not only leads to low produ...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is: to provide a new type of traffic signal lamp, which solves the problem of poor prompting effect for pedestrians with red-green color blindness or color weakness in the prior art, difficulty in replacing some LED lamp beads in the indicator lamp after damage, and the problem that the LED lamp beads are under the power supply voltage. The problem of easy burning when it is too high
