Description

Novel single lamp face LED traffic sign

Technical field

The utility model relates to a kind of traffic signals pilot lamp, and a plurality of mixed light LED of particularly a kind of employing can send the novel single lamp face LED traffic sign of red, yellow or green three kinds of color cressets.

Background technology

At present, in the daily life in the street and crossing place generally be provided with a traffic sign device, current or stop in order to indication pedestrian and vehicle drive people, reach and guarantee traffic safety and smooth and easy fundamental purpose.

Traffic sign; Being commonly called as the traffic signals pilot lamp, is to go up the photochromic signal of mutual replacing with the time of regulation, is arranged at usually and hands over fork in the road or other particular locations; In order to wayleave is specified its whereabouts of control and the traffic control facility that turns to vehicle drive people and pedestrian.Be a traffic control facility by power operation, with red, yellow, green tri coloured lantern number or be aided with sound equipment, indication vehicle and pedestrian stop, noting and advance.

See also accompanying drawing 4; Existing traffic sign 2; Promptly general institute is commonly called as they " traffic lights "; It is to include a red light 21, an amber light 22, a green light 23 (generally being conventional bulb or incandescent lamp bulb) and a support body 24, and is by switching above-mentioned cresset, current or stop with indication pedestrian and vehicle drive people.

Defective below the traffic daily record of using at present exists:

1, the volume heaviness is huge:

Existing traffic sign need be provided with red light, amber light and green light, makes that the volume of whole traffic sign device and weight are all quite big; And the weight of existing logical livery device integral body only relies on single support body to support, and exposes to the sun and rain for a long time, and danger will improve year by year; Especially when running into natural disaster (for example: typhoon or earthquake), existing traffic sign device seriously rocks owing to the overweight meeting of quality, even causes this support body fracture.

2, quite power consumption and not environmental protection:

Pilot lamp in the existing traffic sign (red light, green light, amber light) is generally conventional bulb or incandescent lamp bulb, and its luminescence efficiency is extremely low, and greatly the part electric energy can dissipate with the form of heat energy, quite power consumption and not environmental protection.

3, cost is high:

Pilot lamp in the existing traffic sign (red light, green light, amber light), conventional bulb of being used or incandescent lamp bulb life-span are not long, and damage frequency is high, and needs the professional electrician personnel engineering truck of arranging in pairs or groups to change, quite labor intensive and material resources.

In view of the defective of above 3 of existing traffic sign, the utility model is intended to solve three above defectives, provides that a kind of volume is little, light weight, illumination effect are good, environmental protection, energy-conservation and a kind of novel single lamp face LED traffic sign that cost reduces relatively.

The utility model content

Described display unit is controlled by the parallel circuit of described display unit control module potential circuit, current circuit, frequency circuit.

Described display unit is controlled by the series-parallel circuit of described display unit control module potential circuit, current circuit, frequency circuit.

A kind of LED traffic sign that the utility model provides, its display unit is made up of several mixed lights LED; This display unit control module system is with the circuit in this traffic sign display unit of potential circuit control; More particular it, these mixed lights of the control LED of this display unit control module system sends an identical light of particular color (for example red light, sodium yellow or green light); The utility model is by producing " green cresset ", " red cresset " and " yellow cresset " respectively on single traffic sign display device, can solve existing traffic sign device needs that red light, amber light and green light are set simultaneously, causes the heavy huge shortcoming of volume on a support body.

The utility model is high through the luminescence efficiency of LED, and the characteristic that only has few part electric energy to dissipate with the form of heat energy can effectively solve existing traffic sign and use conventional bulb or incandescent lamp bulb, the suitable power consumption that it is derived and the shortcoming of not environmental protection.

The utility model utilizes the quite long and extremely low characteristic of damage frequency of LED life-span; Effectively solution conventional bulb or incandescent lamp bulb life-span are not long; Damage frequency is high, thereby needs the professional electrician personnel engineering truck of arranging in pairs or groups to change, quite labor intensive and material resources, the high shortcoming of cost.

The utility model utilizes the traffic sign of the color of display unit control module control mixed light LED; Existing three signal lamps are reduced to one; Use mixed light LED to have the quite long and extremely low characteristic of damage frequency of luminescence efficiency height, life-span simultaneously, made traffic sign more reliable, efficient, energy-conservation.

Below in conjunction with accompanying drawing and embodiment, the utility model is further specified.
