Abstract

The utility model relates to a novel electronic traffic signal lamp, which is composed of a straight going symbol lamp, a left turning symbol lamp, a right turning symbol lamp, a panel, a circuit board, resistors, a lamp box and a light shielding cover. The utility model is characterized in that the straight going, the left turning and the right turning symbol lamps all have one, and have larger dimension; the left turning symbol lamp is adjacent to and is positioned at the left of the straight going symbol lamp; the right turning symbol lamp is adjacent to and is positioned at the right of the straight going symbol lamp; thus, the novel electronic traffic signal lamp composed of symbol lamps of three directions is formed. The straight going, the left turning and the right turning symbol lamps are formed by the dense arrangement of monochromatic or discolored LEDs according to directional symbols, and respectively emit the light of three colors of red, green and yellow.

Description

A kind of novel electron traffic lights

The utility model relates to a kind of traffic lights.

At present, be used for the traffic lights of staff vehicles and pedestrian traffic in the urban traffic intersection, generally adopt the current of a crossing of three signal lamp commanders, the crossing in some shunting is to keeping straight on, turning left and turn right and all use one group of red, green, yellow signal lamp separately, the identification of sort signal lamp is complicated, individual signals lamp size is little, the driver of the vehicle far away from the crossing is difficult to select a certain clearance direction running, thereby has reduced the passage rate at crossing.In order to address this problem, at present existing people studies and adopts polychrome monomer electronic communication signal lamp, disclosed as Chinese patent authorization in 22 days March nineteen ninety-five, application number: 94225536.4, the applying date: on January 6th, 1994, the applicant: by-pass is bright, utility model title: monomer electronic communication signal lamp, system adopts a luminosity scale of being made up of variable color light emitting diode or single color LED, replace red, green, yellow three signal lamps, but this utility model does not indicate travel direction, the crossing big with traffic volume in inapplicable shunting.

The purpose of this utility model just is to overcome deficiency and the problem that prior art exists, provide a kind of each travel direction only with one signal lamp, can the shows signal direction, the novel electron traffic lights that also can send out three kinds of color signals red, green, yellow.

The purpose of this utility model adopts following technical scheme to realize.

These novel electron traffic lights, by the craspedodrome code light, the code light of turning left, the code light of turning right, panel, circuit board, resistance, lamp box, light shield is formed, it is characterized in that: the craspedodrome code light, the code light of turning left respectively has only one with the code light of turning right, and size is bigger, keep straight on, turn left, the relative position of code light of turning right is consistent with travel direction, promptly turn left code light near and be positioned at the left side of craspedodrome code light, turn right code light near and be positioned at the right of craspedodrome code light, constitute novel electron traffic lights of forming by three direction symbol lamps, keep straight on, this three code lights of turning left and turn right are made up of according to code light shape dense arrangement single color LED or variable color light emitting diode, and each code light can send red respectively, green, the light of yellow three kinds of colors.

Be described in further detail of the present utility model below in conjunction with embodiment and accompanying drawing.

Fig. 1 is the utility model novel electron traffic lights synoptic diagram.

Fig. 2 is the utility model novel electron traffic signals lamp mounting structure synoptic diagram.

Fig. 3 uses the circuit theory diagrams of the novel electron traffic lights of single color LED for the utility model.

Fig. 4 uses the circuit theory diagrams of the novel electron traffic lights of variable color light emitting diode for the utility model.

1 is craspedodrome code light, the 2nd among the figure, the code light of turning left, the 3rd, the code light of turning right, these three code lights are arranged respectively, thick and fast according to the code light shape by some redness, green, yellow light-emitting diode and are formed, serial or parallel connection is installed on the circuit board 5 respectively then, perhaps arrange thick and fast according to the code light shape and form by some variable color light emitting diodes, serial or parallel connection is installed on the circuit board 5 then, the 8th, the current-limiting resistance of light emitting diode, panel 4 is dark white edge frame, can improve the contrast of signal lamp, lamp box 6 fronts are equipped with light shield 7.

Figure 3 shows that this novel traffic signal lamp uses the circuit of single color LED, R is the current-limiting resistance of light emitting diode, and operating voltage is for exchanging 40 volts.SR, SG, SY are respectively the power inputs of craspedodrome code light redness, green, yellow light-emitting diode, LR, LG, LY are respectively the power inputs of code light redness, green, yellow light-emitting diode of turning left, RR, RG, RY are respectively the power inputs of code light redness, green, yellow light-emitting diode of turning right, and N is a power supply public input end altogether.The red light emitting diodes of craspedodrome code light, the code light of turning left, the code light of turning right is luminous respectively when SR, LR, RR input voltage, and craspedodrome code light, the code light of turning left, the code light of turning right take on a red color; The green LED of craspedodrome code light, the code light of turning left, the code light of turning right is luminous respectively when SG, LG, RG input voltage, and it is green that craspedodrome code light, the code light of turning left, the code light of turning right are; The yellow light-emitting diode of craspedodrome code light, the code light of turning left, the code light of turning right is luminous respectively when SY, LY, RY input voltage, and it is yellow that craspedodrome code light, the code light of turning left, the code light of turning right are.

Figure 4 shows that this novel traffic signal lamp uses the circuit of variable color light emitting diode, R is the current-limiting resistance of light emitting diode, and operating voltage is for exchanging 5 volts.SR, SG are respectively redness, the green power supply input ends of craspedodrome code light variable color light emitting diode, LR, LG are respectively turn left redness, the green power supply input end of code light variable color light emitting diode, RR, RG are respectively turn right redness, the green power supply input end of code light variable color light emitting diode, and N is a power supply public input end altogether.The variable color light emitting diode of craspedodrome code light, the code light of turning left, the code light of turning right glows respectively when SR, LR, RR input voltage, and craspedodrome code light, the code light of turning left, the code light of turning right take on a red color; The variable color light emitting diode of craspedodrome code light, the code light of turning left, the code light of turning right difference green light when SG, LG, RG input voltage, it is green that craspedodrome code light, the code light of turning left, the code light of turning right are; When SR and SG, LR and LG, RR and the RG variable color light emitting diode of craspedodrome code light, the code light of turning left, the code light of the turning right light that turns to be yellow respectively during input voltage simultaneously, it is yellow that craspedodrome code light, the code light of turning left, the code light of turning right are.

The utility model novel structure, succinct is discerned nature, convenience, can improve the traffic volume of traffic intersection, the generation of minimizing accident.
