Abstract
The utility model provides a light-emitting diode (LED) street light capable of automatically adjusting illumination, which comprised a casing, LED light sources and a circuit board. The LED light sources and the circuit board are arranged inside the casing. The LED street light is characterized by further comprising a controller which is arranged inside the casing and connected with the circuit board. The controller is used for controlling input voltage of the LED light sources so as to adjust illumination of the street light. The LED street light capable of automatically adjusting illumination has the advantages of being simple in structure, low in cost and high in applicability.
Description
Technical field
The utility model relates to the LED lighting engineering, particularly relates to a kind of LED street lamp that can regulate illumination automatically.
Background technology
Led light source is to be the light source of illuminator with light emitting diode (LED), the LED technology comes from the sixties in 20th century, led light source has efficient height, long characteristics of life-span, its energy conversion efficiency is very high, under the equal illumination, compare, have obvious energy-saving effect with other lighting engineering, only be equivalent to 10% of incandescent lamp as its energy consumption, be equivalent to 50% of fluorescent lamp; And led light source required voltage, electric current are all less, and it is also less to generate heat, and does not have potential safety hazard generally speaking, is the good lighting engineering of a kind of security performance; Led light source can not produce the leakage of materials such as mercury and pollute, and is a kind of light source of environmental protection.
The LED lighting engineering has all obtained huge application and popularization in vast field, particularly aspect the huge street lamp application of power consumption, based on its considerable energy saving characteristic, has obtained development fast especially.
For the LED street lamp, the self-powered led street lamp technology of photovoltaic generation of extensive use at present, significant progress and application have been obtained, but, because the photovoltaic generation cost is higher, the size of the power consumption of light source has directly determined the power of photovoltaic cell, if can reduce the power consumption of light source, can directly significantly reduce the cost of the photovoltaic cell system of required outfit.
Because people's habits and customs, determined street lamp along with the passing of time at nightfall, needed illumination is also different, the first half of the night, people's outdoor activities are more, and higher illumination need be provided, after midnight, outdoor activities significantly reduce, and the illumination that need provide is also lower, therefore, if can adjust the illumination of street lamp along with people's habits and customs and needs, reduce unnecessary power consumption, can cut down the consumption of energy, reduce cost.
The utility model content
At present situation of the prior art, the purpose of this utility model is to provide a kind of LED street lamp that can regulate illumination automatically.
The technical solution of the utility model is as follows:
A kind of LED street lamp of automatic adjusting illumination, comprise housing and be arranged on housing interior led light source and circuit board thereof, it is characterized in that: described LED street lamp also comprises controller, described controller is arranged in the housing, and link to each other with described circuit board, be used to control the input voltage of led light source to regulate street lamp illumination.
Optionally, described led light source comprises a plurality of or the many groups of LED spot lights that work alone.
Optionally, described a plurality of or many groups of LED spot lights that work alone are used alone or in combination under the control of controller.
Technique effect of the present utility model is:
The utility model is regulated the input voltage of led light source to regulate LED street lamp illumination by controller is set on circuit board.
Simultaneously, the utility model also is divided into the LED spot light some independent lighting units, and under the control of controller, control is one or more groups light source cell work wherein, so that the illumination of different illumination to be provided.
The utlity model has simple and reasonablely, cost is low, characteristic of strong applicability.
Description of drawings
Figure 1 shows that the structural representation of road lamp body of the present utility model.
Reference numeral lists as follows: 1-housing, 2-controller, 3-circuit board, 4-LED spot light.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, the LED street lamp for a kind of embodiment of the present utility model comprises housing 1, is provided with controller 2 and circuit board 3 in the housing 1, and controller 2 links to each other with circuit board 3, and circuit board 2 is provided with some LED spot lights 4.
