Traffic signal light control method, device and system based on mixed color light

Abstract

The invention discloses a traffic signal lamp control method, device and system based on mixed colored light, applied to a traffic signal lamp comprising a first color signal lamp, a second color signal lamp and a third color signal lamp, and the first color signal lamp emits a light signal of a first color through a first light emitting module; the second color signal lamp emits a second color light signal through the second light emitting module; the third color signal lamp emits a first color light signal through the third light emitting module and emits a second color light signal throughthe fourth light emitting module. The method comprises the step of controlling the light-emitting modules, emitting the light signals of the same color, in the signal lamps of different colors to be replaced according to the utilization rate of the signal lamps of different colors in the traffic signal lamps and the rated working duration of the light-emitting modules in the signal lamps of different colors. The overall service life of the traffic signal lamp can be prolonged by replacing the light-emitting modules of different colors of signal lamps in the traffic signal lamp.

Description

technical field [0001] The invention relates to the field of optical signal control, in particular to a traffic signal light control method, device and system based on mixed color light. Background technique [0002] This section is intended to provide a background or context to embodiments of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] As we all know, traffic lights play a very important role in the safe operation of roads by using signal lights of different colors to drive vehicles on the road or to indicate pedestrians on the road. [0004] Most traffic lights include three colors of red lights, green lights and yellow lights. The basic principles of operation are as follows: ① When the red light is on, vehicles or pedestrians are prohibited from passing; ② When the green light is on, vehicles or pedestrians are allowed to pass; ③ When the yellow light is on , indicating th...

Problems solved by technology

[0008] An embodiment of the present invention provides a traffic signal light control method based on mixed color light, which is used to solve the technical problem that the overall service life of the traffic signal light is low due to the different working hours of the signal lights of different colors in the existing traffic signal lights. The first color signal lamp, the second color signal lamp and the traffic signal lamp of the third color signal lamp, the first color signal lamp includes: a first light emitting module; the second color signal lamp includes: a second light emitting module; the third color signal lamp includes: a third light emitting module and the fourth light-emitting module; the first light-emitting module and the third light-emitting module are used to send out the light signal of the first color; the second light-emitting module and the fourth light-emitting module are used to send out the light signal of the second color, and the light signal of the first color and The optical signal of the second color is mixed to obtain the optical signal of the third color
