Abstract

The utility model discloses a LED traffic signal lamp, comprising a lamp house, LED lamps installed inside the lamp house and an integrated light-source plate. The integrated light-source plate comprises a circuit board and a convex lens board on which a plurality of convex lenses are arranged; the LED lamps are arranged on the circuit board to form a LED lamp array; the shape of the LED lamp array depends on the traffic sign; the convex lens board is fixed above the LED lamp array and the space length is equal to the focus of the convex lens; the convex lenses correspond to the LED lamps. The LED traffic signal lamp has the advantages of the integrated light-source plate, simple structure, easy fabrication, sound exchangeability and sound visual effect.

Description

A kind of LED traffic lights

Technical field

The utility model relates to the traffic signals identification light of a kind of use light emitting diode (Light Emitting Diode LED).

Background technology

Traffic lights are alarm signal lamps that the needs according to highway, high-grade highway and cruiseway design, and original traffic sign lamp is installed incandescent lamp in lampshade, can only show the two states that flickers, power consumption is many, and light source life is short, and cost is than higher.The present identification light of urban traffic intersection except will providing the signal whether red and green expression let pass, will demonstrate craspedodrome, turn left and bend or the curved sign of turning right toward contact.

LED is a kind of solid-state semiconductor devices, it can directly be converted into light to electricity, can make up the light fixture of making various external forms, and response speed is fast, no stroboscopic, merge with present various intellectual technologies easily, color is abundant, and is also energy-conservation, it is 1/10 power consumption of conventional light source, the theoretical life-span of LED can reach 100,000 hours, and make lamp life and can reach more than 50,000 hours, be the life-span more than 10 times of conventional light source.

Summary of the invention

The purpose of this utility model is to provide a kind of traffic lights that use led light source, can show traffic sign.

The disclosed a kind of LED traffic lights of the utility model comprise lampshade and are installed on the interior LED lamp of lampshade that also comprise integrated light source board, described integrated light source board comprises wiring board and is distributed with the lenticular lens sheet of convex lens one by one; Described LED lamp is arranged in LED lamp array on described wiring board, the shape of described LED lamp array is by the shape decision of traffic sign; Described lenticular lens sheet is fixed on the top of described LED lamp array and the focal length that distance equals described convex lens, and described convex lens and described LED lamp are corresponding one by one.

LED traffic lights of the present utility model also comprise the regulator rectifier circuit that is used for LED lamp power supply on described wiring board.

Traffic lights of the present utility model use the LED of high brightness to arrange, part series adopts the great power LED pipe, luminosity is strong, sense of vision good, signal is clear, the moistureproof and waterproof performance is good, is service life more than 100,000 hours, is indispensable security warning facility in the traffic.Being applicable to highway and traffic fork in the road and hazardous location, is that the requisite facility of management has been arrived in traffic, plays and reminds the driver to note the fork in the road, and careful driving reduced the effect that traffic accident takes place.

Description of drawings

The utility model comprises following as figure:

Fig. 1 is the integrated light source board of traffic lights of the present utility model.

Fig. 2 is the profile of the AA face of Fig. 1.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is described further.

In the accompanying drawing: 10 is wiring board, and 12 is the LED lamp, and 11 is lenticular lens sheet.What same label was indicated in the accompanying drawing is same parts.

The utility model provides a kind of traffic lights, adopts LED as light source, has integrated light source board, and is simple in structure, makes easily, and interchangeability is good, and improvement expenses is low.

This traffic lights comprise lampshade and integrated light source board, this integrated light source board can directly be replaced out the light source in the old-fashioned traffic lights, what for example old-fashioned traffic lights used is incandescent lamp, because in the wiring board of integrated light source power circuit is arranged, so can directly replace lamp bulb, and become LED traffic lights of the present utility model.

As shown in Figure 1, be the structural representation of integrated light source board of the present utility model, comprise wiring board 10, power circuit is arranged in the circuit board, LED lamp array (as Fig. 2, invisible among Fig. 1) is arranged, power circuit is the power supply of LED lamp array.In LED lamp array upper fixed lenticular lens sheet 11 is arranged, on lenticular lens sheet, be distributed with convex lens one by one, corresponding one by one with LED lamp in the LED lamp array, the direction of light that the LED lamp sends is adjusted.

As shown in Figure 2, be the profile of the AA face of Fig. 1, handed over the relation one to one of lenticular lens sheet and LED lamp array.The distance of lenticular lens sheet and led array makes the LED spot light on the focus of convex lens, and the light that LED sends has strengthened the directionality and the visual intensity of light through forming the equidirectional collimated light beam of a branch of bundle behind the convex lens.

Lenticular lens sheet can use the optics plastic rubber shaping.

LED lamp arrayed becomes the shape of traffic sign regulation.

Claims

1. LED traffic lights comprise lampshade and are installed on the interior LED lamp of lampshade, it is characterized in that, also comprise integrated light source board, described integrated light source board comprises wiring board and is distributed with the lenticular lens sheet of convex lens one by one; Described LED lamp is arranged in LED lamp array on described wiring board, the shape of described LED lamp array is by the shape decision of traffic sign; Described lenticular lens sheet is fixed on the top of described LED lamp array and the focal length that distance equals described convex lens, and described convex lens and described LED lamp are corresponding one by one.

2. LED traffic lights according to claim 1 is characterized in that, also comprise the regulator rectifier circuit that is used for LED lamp power supply on the described wiring board.
