Abstract
An energy-saving environment-friendly road traffic light relates to the road traffic signal marks, which comprises a light-emitting diode, and is characterized in that the output end of a bridge rectification circuit is connected with a parallel LED lamp groups, and the LED lamp is formed by a plurality of series resistances and light-emitting diodes which are reduced in voltage in stages. And three parallel LED lamp groups are provided, and the diode of the bridge rectification circuit is a high-pass diode. The utility model has the beneficial effects of effectively reducing electricity consumption, increasing power, reducing heat radiation, and reaching the energy-saving and environment-friendly purposes. The power coefficient of electricity exchange reaches to 98% after being tested, which increases 1-2 times than current 30-50%.
Description
Technical field
The utility model relates to the road traffic signal sign, especially the road traffic signal lamp of light emitting diode formation.
Background technology
Road traffic signal lamp is important traffic safety facilities, and to safeguarding the road traffic order, the guarantee traffic safety is being brought into play important effect.The construction of current social city is very rapid, and traffic lights use very extensive.But existing road traffic signal lamp generally adopts the transformer step-down, and power factor is very low, and energy consumption is very big, also causes heat radiation to pollute in the time of power consumption.This has bigger gap with current energy-saving and cost-reducing, the environmental protection requirement of advocating.The energy-conserving and environment-protective of signal lamp have become the very worth important problem of urban construction.Therefore, the road traffic signal lamp of exploitation energy-conserving and environment-protective is current very real and need the urgent problem that solves.
The utility model content
The purpose of this utility model provides a kind of new road traffic lights of energy-conserving and environment-protective.The sort signal lamp, power factor is big, and power consumption is little, can not cause heat radiation to pollute as cold light source, possesses environmental protection function.
The purpose of this utility model reaches like this:
A kind of energy saving and environment friendly road traffic signal lamp contains light emitting diode, it is characterized in that: the output at bridge rectifier connects LED lamp group in parallel, and the LED lamp is made of the series resistance of several classification step-down and the light emitting diode of series connection.
LED lamp group in parallel has three groups.
The diode of bridge rectifier is the high pass diode.
Good effect of the present utility model is: effectively reduce power consumption, improved power, reduce heat radiation, reach the purpose of energy-conserving and environment-protective.After tested, the power factor of electric energy conversion improves 1～2 times up to 98% than existing 30～50%.
Description of drawings
Accompanying drawing is a circuit structure schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described further.
Referring to accompanying drawing.
Road traffic signal lamp is super bright cold light source lamp.Adopt the purpose that reaches step-down of the light emitting diode series connection classification connected mode of identical resistance of resistance and same model.The process of step-down does not adopt the mode of transformer or capacitance-resistance, effectively reduces power consumption.
The diode of bridge rectifier is the high pass diode.What present embodiment adopted is high pass diode 5408.LED lamp group in parallel is three groups, respectively as red, yellow, green coston light.Wherein the light emitting diode of classification step-down has adopted 32 series connection for every group, and resistance is 4 the 4.7K resistance of having connected.The effect of LED lamp has reached the effect of super bright cold light source.
Claims (3)
