Abstract
Currently, traffic indicator lights of urban roads all adopt filament lamps, and the indicator lights have the disadvantages of short service life of lamp bulbs, requirement of frequent repair and large electric power consumption. The utility model relates to the novel traffic indicator light which comprises a casing and a light emitting source. The utility model is characterized in that the light emitting source is formed by connecting a plurality of LED luminous tubes in series and in parallel. The utility model relates to a low-energy cold light source, so the nominal power is only one seventh of the old indicator light, the electric power consumption is about one eighth of the old indicator light, the mean service life can enhance from three times to five times, and the brightness and the evenness are totally exceed the old road indicator lights.
Description
The utility model is a kind of road traffic indicator light.
The urban highway traffic pilot lamp all is to adopt incandescent lamp at present, and the shortcoming of this pilot lamp is: bulb life is short, often need repairing, and power consumption is big.
The purpose of this utility model provides a kind of novel traffic pilot lamp, and it can overcome existing shortcoming in the prior art, realizes high brightness, low energy consumption, long-life.
The purpose of this utility model is achieved in that it comprises shell and light emitting source, it is characterized in that its light emitting source adopts a plurality of LED luminotron connection in series-parallel to form.
Road traffic indicator light of the present utility model is the low energy cold light source, therefore rated power is 1/7th of old-fashioned pilot lamp, power consumption is about 1/8th of old-fashioned pilot lamp, can improve 3-5 average life doubly, and owing to be that a plurality of small light sources combine, so brightness and uniformity coefficient all surpass old-fashioned road indicating lamp.
In order further to improve serviceable life of the present utility model, can be one group with several luminotron parallel connections, will organize series system more then and become light emitting source of the present utility model.
In addition can also be with light emitting source with black polyurethane or unsaturated polyester embedding, strengthening its contrast, thereby can advance a brightness that improves luminotron.
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing thereof.
Fig. 1 is a structure cut-away view of the present utility model.
Fig. 2-Fig. 4 is the schematic circuit of three kinds of embodiment of the present utility model.
4 is shells among the figure, and the front has snoot, has the serviceable life that is close with luminotron in order to make it, and shell adopts engineering plastics to make.3 is LED luminotrons among Fig. 1, the 2nd, and wiring board, the light emitting source that the LED luminotron is formed is perhaps used the unsaturated polyester embedding with black polyurethane 1 solid envelope.More luminotron can be organized and directly be connected on (as Fig. 2) in the power supply shown in Fig. 2-4, can be one group with several parallel connections also, and with each group series connection (as Fig. 3,4), the utility model adopts the AC180-220V power supply then.
Claims (3)
1, a kind of new road traffic lights, it comprises shell and light emitting source, it is characterized in that its light emitting source adopts a plurality of LED luminotron connection in series-parallel to form.
2,, it is characterized in that several luminotron parallel connections are one group, will organize series system more then and become light emitting source of the present utility model according to the said traffic lights of claim 1.
