Abstract
The utility model discloses a road traffic command device, particularly relates to a road traffic signal light applied to road traffic command. The road traffic signal light comprises a light source and an illuminant disc; the light source adopts tricolor (red, yellow and green) LBD, vertically and horizontally arranged in a certain order and interval on the illuminant disc. The utility model is characterized in that a red LBD (101) is connected to the two output ends of the bridge rectifier after serial connection with the current-limiting resistor; the yellow LBD (102) is connected to the two output ends of the bridge rectifier after serial connection with the resistor; the two output ends of the bridge rectifier are respectively connected to the output end of the transformer. The utility model is capable to overcome the defects of the prior art, has the advantages of a compact structure, small size, light weight, low cost, etc.
Description
Technical field
The utility model relates to a kind of road traffic command device, especially for a kind of road traffic signal lamp of road traffic commander.
Background technology
The light source of road traffic signal lamp adopts incandescent lamp more at present, is furnished with the structure of colored lights cover.Existing red yellowish green trichromatism traffic lights form for red, yellow, green three-color light source is loaded on respectively on three luminosity scales.The traffic lights cost height of this structure, big, the Heavy Weight of volume.
Summary of the invention
The purpose of this utility model is to overcome the defective that prior art exists, and provides a kind of structural design compactness, little, the lightweight road traffic signal lamp of volume.
The purpose of this utility model is achieved through the following technical solutions: this road traffic signal lamp, comprise light source, luminosity scale, its light source adopts red, yellow, green Tricolor LED, they are orderly, arrange in length and breadth the compartment of terrain, be loaded on the luminosity scale, its design feature is: two output terminals that connect bridge rectifier after the described red light emitting diodes series limiting resistor, connect two output terminals of bridge rectifier after the yellow light-emitting diode series limiting resistor, connect two output terminals of bridge rectifier after the green LED series limiting resistor, the output terminal of two input termination transformers of bridge rectifier.This structure with red, yellow, green three look traffic lights compactnesses in same luminosity scale.
The utility model compared with prior art has the following advantages: 1, adopt the light source of light emitting diode as traffic lights, and with red, yellow, green Tricolor LED, be loaded in the same luminosity scale, the power supply of light emitting diode is provided by bridge rectifier and transformer, this reasonable in design compactness, low cost of manufacture.2, these traffic lights change red, yellow, green three luminosity scales of prior art into a luminosity scale and send out three kinds of indication looks, under the prerequisite that guarantees the signal lamp result of use, reduce the pilot lamp volume, alleviated weight, lowered the requirement of pilot lamp, thereby reduced the cost of whole road traffic signal lamp the lamp stand bearing capacity.
Description of drawings
Fig. 1 is that light emitting diode is arranged synoptic diagram in the utility model luminosity scale.
Fig. 2 arranges local side-looking enlarged drawing for light emitting diode.
Fig. 3 is the utility model wiring electrical schematic diagram.
Referring to Fig. 1, Fig. 2, present embodiment comprises light source, luminosity scale.Light source adopts light emitting diode 1, and the light emitting diode 1 of different colours is loaded on the luminosity scale 2.Light emitting diode 1 is red light emitting diodes 101, yellow light-emitting diode 102, green LED 103, and their intervals, arrangement in an orderly manner are loaded on the luminosity scale 2.Red light emitting diodes 101, yellow light-emitting diode 102, green LED 103 connect two output terminals of bridge rectifier respectively after the series limiting resistor, the output terminal of two input termination transformers of bridge rectifier.
The circuit connection of embodiment as shown in Figure 3, the red light emitting diodes 101 of series connection is two output terminals that meet bridge rectifier B1 parallel with one another behind the serial connection current-limiting resistance, equally, two output terminals that meet bridge rectifier B2 parallel with one another behind the yellow light-emitting diode 102 serial connection current-limiting resistances of series connection, two output terminals that meet bridge rectifier B3 parallel with one another behind the green LED 103 serial connection current-limiting resistances of series connection, two input ends of bridge rectifier B1, B2, B3 connect the output terminal of transformer T1, T2, T3 respectively.R1-R9 is respectively the current-limiting resistance that is serially connected in behind red, yellow, the green Tricolor LED among the figure
This road traffic signal lamp in use, the control signal of sending according to traffic light controller, the power supply of difference conducting or cut-out red light emitting diodes 101, yellow light-emitting diode 102, green LED 103, thus make these traffic lights send the yellow or green traffic signals pilot light of redness respectively.
