Problems solved by technology

[0004] At least two kinds of traffic lights are required at a 'cross' intersection, and at least four of each are installed, which increases the use of signal lights and consumes manpower
In addition, studies have shown that many drivers have mild color blindness, are not sensitive to a single color, and have difficulty identifying traffic lights at intersections

Abstract

The invention discloses an LED traffic signal lamp with double light-emitting sides. The LED traffic signal lamp comprises a first mounting shell, a radiating plate, a first LED light source, a control device, a collimating device, a hollow frustum-cone-shaped light splitter and a first lampshade, wherein the first lampshade is connected with the first mounting shell, the first LED light source is arranged on the radiating plate, the collimating device is disposed between the light splitter and the first LED light source, the side face of the light splitter is a total-reflection face, and the first LED light source comprises red, green and yellow LED chips. The LED traffic signal lamp with the double light-emitting sides has the advantages that the double sides of the LED traffic signal lamp can emit light simultaneously, so that consumption of traffic signal lamps at the intersections is reduced; through combination of colors of an original traffic signal lamp and characters, drivers with slight color blindness can judge driving orders at the intersections visually easily.

Description

[0001] Technical field: [0002] The invention relates to the field of LED lighting, in particular to a double-sided LED traffic signal light. [0003] Background technique: [0004] At least two kinds of traffic lights are needed at a 'cross' crossing, and four of each kind are installed at least, which has both increased the usage of signal lights and expends manpower. In addition, studies have shown that many drivers have mild color blindness, are not sensitive to a single color, and have difficulty identifying traffic lights at intersections. [0005] Invention content: [0006] In order to solve the above-mentioned deficiencies in the prior art, a double-sided LED traffic signal light provided by the present invention is characterized in that: the traffic signal light can emit light on both sides at the same time, reducing the usage of signal lights at intersections; The combination of words makes it easy for drivers with slight color blindness to intuitively judge the d...
