COMPonENTS OF TRAFFIC SIGNAL LIGHT

1/Optical system
Consists of optical elements such as light sources, mirrors, lenses, color films, etc., which are used to generate signal lights, including the color, brightness and A system that specifies specific optical effects, such as a geometric image of light.
2/Geometric axis
A straight line that is perpendicular to the horizontal projection plane of the light emitting surface and passes through the geometric center of the light emitting surface.
3/Visor
Installed on the outer edge of the light unit of the signal lamp, used to reduce the interference of the optical effect of the signal lamp by the external light source, and increase the brightness of the signal.Ratio and color saturation baffle.
4/Colour slice
A component that generates colored light in a transparent manner and protects internal components.
5/Side edge angle of cover
The included angle between the vertex of the line segment intercepted by the horizontal section of the center of the light emitting surface and the center of the light emitting surface.
6/Countdown digital display counting down display
The device that uses seven-segment digital display to display the remaining time of the current lamp color is an optional accessory for signal lights.
