Abstract

The novel traffic signal lamp with concentrated light source has mainly one rotating regular octahedron. The light source is positioned at the center of the regular octahedron. The regular octahedron has red, green and yellow transmitting material separately on its eight planes, crosses four planes aiming at the four directions of the road crossing and the other four planes shielded by fixed light diaphragms. When the regular octahedron rotates around its axle by one 45 deg, the signal lamp in one direction changes its color, from red to yellow, to green, to red successively to complete the entire function of one traffic signal lamp. The present invention has the features of simple structure, high visibility, saving electric power, long life, etc.

Description

Novel traffic signal lamp

The invention belongs to the urban highway traffic signal light.

Existing traffic signal lamp is at each crossing and is provided with one group, and promptly the crossroad of standard has four groups, and some crossroad more has at both forward and reverse directions and respectively establish one group, then has eight groups of signal lights at four crossings.Because every group of signal light has red, green, yellow tri coloured lantern, therefore general crossroad adds up to 12 to 24 signal lights.Because every signal light goes out when bright during all along with traffic, so very easily damage, power consumption is also very big simultaneously again, because general signal light is installed in walkway, crossing one side, more easily blocking because of shade tree influences result of use in addition.

Consider the defective of existing traffic signal lamp, traffic signal lamp of the present invention adopts central source centralized, its main composition is: on a regular octahedron, each face is lattice, as being preface with same direction, then 1,5 lattice are red light transmissive material, and 3,7 lattice are green light transmissive material, and all the other 2,4,6,8 lattice are yellow light transmissive material.This regular octahedron is that axle is by rotating clockwise or counterclockwise with the center of circle, revolution one lattice are 45 °, establish a long column shape electric light source at home position simultaneously, establish stationary barrier between every lattice in addition, wherein 1,3,5,7 lattice are the printing opacity lattice, and 2,4,6,8 lattice are light tight lattice.

This novel traffic signal lamp should be installed on centre top, crossroad.As the luminous Hou of electric light source, 1,3,5,7 lattice transmitted lights, wherein 1,5 lattice are red light transmissive material, thus be the red light shape at 1,5 lattice, and this moment, 3,7 lattice were green light transmissive material, so be the green light shape at 3,7 lattice.At this moment, accurate same the positive and negative both direction in road of 1,5 lattice timings, and 3, the 7 lattice positive alignments vertical positive and negative both direction in another road in bar road therewith, form red, green light phase, and all the other four lattice are light tight dividing plate in order to shut out the light.When this regular octahedron is that axle rotates the i.e. 45 ° of Hous of lattice with the center of circle, red light transmissive material goes to 2,6 light tight lattice, and green light transmissive material goes to 4,8 light tight lattice, meanwhile, 2,4,6,8 yellow light transmissive materials go to 1,3,5,7 lattice, and this moment, four transparent surfaces all were the amber light shape.As rotating the i.e. 45 ° of Hous of lattice this moment again, 1,5 lattice will be the green light shape, 3,7 lattice are the red light shape, finished thus traffic signal lamp by " red " commentaries on classics " Huang ", by " Huang " commentaries on classics " green " again by the overall process of " green " commentaries on classics " red ", and can repeatedly or recycle.

Primary structure is made up of three parts, that is:

(1) regular octahedron: be installed on the regular octahedron with red, yellow, green three kinds of light transmissive materials respectively, by its order 1,5 lattice for red, 3,7 lattice for green, all the other are yellow, this regular octahedron can be around its axle center by rotating clockwise or counterclockwise, and revolution one lattice are 45 °.

(2) stationary barrier: this dividing plate and shell be fixedly connected (seeing accompanying drawing).

(3) utility appliance such as shell, signal light lifting or stationary installation, electronic or manual overvide.

This traffic signal lamp is applicable to the positive crossroad of urban road, it is very eye-catching to be installed on crossing central authorities (lifting or pillar are installed), owing to have only a light emitting source, and electrified light emitting all the time, but not only power saving but also can not shorten serviceable life of light emitting source because of frequent switch.

Claims

Novel traffic signal lamp, be different from existing traffic signal lamp fully, it is in the face of four crossings, have only a unique light source, its primary structure is mainly by a regular octahedron, on form by red, yellow, green three kinds of transparent materials by three kinds respectively, pressing clockwise (or anticlockwise) rotates, change the signal of different colours, reach the purpose that directs traffic, other also has every tabula rasa and shell.
