The LED streetlamp disclosed by the utility model has the advantages of convenience in maintenance and control and uniformity in brightness.

Description

The LED street lamp

Technical field

The utility model relates to a kind of LED street lamp, belongs to technical field of semiconductor illumination.

Background technology

At present, LED is because the characteristics of its energy-conserving and environment-protective become the preferred light source of green illumination, and city lighting and Landscape Lighting are the maximum fields of lighting demand, so large LED engineering project in recent years concentrates on city lighting illumination and Landscape Lighting field mostly.

Street lamp adopts LED to replace existing HID light fixture as using the most general light fixture in the city lighting, can practice thrift the electric energy more than 70%, because the relative HID with lamp body of power supply of LED has great life-span advantage, has also reduced the maintenance and the maintenance cost in later stage.Also there is brightness curve from low to high in HID street lamp before in the process of lighting, when promptly switching on rectifier and lamp body preheating darker, after a while along with temperature rising brightness just can be risen; And the HID light fixture is difficult to regulate brightness at brushend; Has only a bulb in each lamp body; Has the hand operated control method that to take a plurality of street lamps to use at interval under the situation that certain environment brightness only needs the street lamp light filling with haze etc. between the lights; The street lamp wiring of this method increases with the complexity of control, and cost is higher; And at interval illumination makes the brightness disproportionation on road surface, and too bright under the opened street lamp, brightness is dark partially under the street lamp of not opening.

The utility model content

The technical problem that the utility model will solve is, proposes a kind ofly can realize that brightness evenly and can self-regulating LED street lamp.

The utility model is that the technical scheme that solves the problems of the technologies described above proposition is: a kind of LED street lamp; Comprise lamp body, controller, power supply and light sensor; Power supply connects controller, and the bottom of lamp body is provided with at least two group LED modules, and the input of LED module connects the output of controller; Light sensor is located at the top of lamp body, and the output of light sensor connects the input of controller.

The improvement of the utility model LED street lamp is also to be provided with carrier receiving module in the controller.

During use, the general supply end utilizes the power line carrier transmitter module that control signal is added in the power line, and the carrier receiving module of controller promptly reads the control command in the power line carrier and lets controller carry out corresponding operation.

The LED street lamp of the utility model is compared existing street lamp owing to adopt the structure of the many groups of light sensor control LED, and the beneficial effect that has is:

1.LED low in energy consumption, long service life has been saved the maintenance and the maintenance cost in later stage.

2. can select several module brightness of illuminations according to available light through light sensor and controller, not need complicated on-off control system.

3. every LED street lamp is all in work when selecting different brightness to throw light on, and just the usage quantity of LED module changes in the lamp body, and the range of exposures of every street lamp is constant, and the brightness on road surface is even.

4. can under the prerequisite that does not increase holding wire, carry out Long-distance Control through power line carrier to street lamp behind the carrier receiving module of setting up in the controller, cost is low and flexibility is strong.

Description of drawings

Be described further below in conjunction with the LED street lamp of accompanying drawing the utility model.

Fig. 1 is the structured flowchart of the utility model embodiment one.

Fig. 2 is the structured flowchart of the utility model embodiment two.

Embodiment

Embodiment one

The LED street lamp of present embodiment is as shown in Figure 1; Comprise lamp body, controller and light sensor; The bottom of lamp body is provided with LED module 1 and LED module 2; LED module 1 and LED module 2 input all be connected to the power output end of controller, light sensor is located at the top of lamp body, the output of light sensor connects the signal input part of controller.

Embodiment two

The LED street lamp of present embodiment is the improvement on embodiment one basis, and is as shown in Figure 2, and its improvements are, in controller, have additional carrier receiving module, thereby can utilize power line carrier that street lamp is carried out Long-distance Control.

During use; The LED street lamp of present embodiment is installed in the open air; The light sensor at lamp body top is used to measure the illumination of natural daylight; Need light the natural daylight illumination threshold value 1 of street lamp according to actual needs in advance in the controller setting, when the illumination of light sensor collection was lower than subthreshold 1, controller can be supplied with LED module 1 with power supply; Set the natural daylight illumination threshold value 2 of street lamp highest luminance according to actual needs in advance at controller, when the illumination of light sensor collection was lower than subthreshold 2, controller can be supplied with LED module 1 and LED module 2 with power supply; When the illumination of light sensor collection was higher than threshold value 1, controller can be managed powered-down.

Can control signal be delivered to controller through power line through the power line carrier reflector at the street lamp Master Control Center, thereby realize remote handle adjusting brightness.

The LED street lamp of the utility model is not limited to above-mentioned each embodiment, and for example the quantity of LED module can add up on the basis of existing embodiment, and in controller, sets corresponding threshold value to increase the progression of light modulation.All employings are equal to the technical scheme that replacement forms, and all drop on the protection range of the utility model requirement.
