Abstract

The utility model discloses a novel low-power LED energy-saving street lamp which comprises a street lamp post and a light fitting shell arranged at the upper end of the street lamp post, wherein the light fitting shell is internally provided with a light fitting board which is provided with a plurality of LED lamps; the novel low-power LED energy-saving street lamp is characterized in that the back of the light fitting shell is provided with a grid-shaped radiating fin connected with a light fitting shell body; a transparent glass plate is covered outside the LED lamps and is fixed on the light fitting shell which is provided with a photosensitive sensor; a singlechip control circuit is connected with the photosensitive sensor; the singlechip control circuit comprises a singlechip and a memorizer; each LED lamp is connected with a corresponding LED lamp light-emitting driving chip; and all the LED lamp light-emitting driving chips are connected on the singlechip control circuit. At night, the LED lamp light-emitting driving chips are controlled to turn on the LED lamps by the singlechip control circuit, and the street lamp starts to work; and in the morning, the lightened LED lamps are turned off by the singlechip control circuit, so that the street lamp stops working.

Description

A kind of novel low-power LED energy-conserving road lamp

Technical field:

The utility model relates to a kind of novel low-power LED energy-conserving road lamp product.

Background technology:

Its light fixture of transitional street lamps generally adopts fluorescent lamp, can not be energy-conservation, again because present street lamp is taked Artificial Control mostly, road lamp management personnel's labour intensity can be very big like this, simultaneously, administrative staff's sense of responsibility can have influence on the switch time of street lamp, the too early or time-delay phenomenon of switch lamp occurs, open lamp too early causes unnecessary electricity consumption matter of time; Open lamp is too late, causes people's problem of having inconvenient traffic.

Summary of the invention:

At the problem that above prior art exists, the utility model provide a kind of energy-conservation, can according to weather brightness automatically control reach the novel low-power LED energy-conserving road lamp of switch lamp, applicable to the illumination of highway, street, square, public place of entertainment etc.

The purpose of this utility model is to realize like this, described a kind of novel low-power LED energy-conserving road lamp, comprise lamppost and the lamp outer casing that is contained in the lamppost upper end, in lamp outer casing, be provided with the light fixture plate, the light fixture plate is provided with a plurality of LED lamps, its design feature is for being provided with the palisade fin with lamp outer casing body disjunctor at the lamp outer casing back, the employing transparency glass plate covers LED lamp outside and is fixed on the lamp outer casing, lamp outer casing is provided with light sensor, one single chip machine controlling circuit connects light sensor, single chip machine controlling circuit comprises single-chip microcomputer and memory, described each LED lamp is connected with the luminous driving chip of a corresponding LED lamp, and the luminous driving chip of each LED lamp is connected on the single chip machine controlling circuit.

The beneficial effects of the utility model are: the utility model is equipped with low power LED lamp on the light fixture plate, the light fixture plate of fixing low power LED lamp once is pressed into aluminium alloy, its good heat dissipation effect, light fixture plate place in the lamp outer casing that an aluminium alloy makes and link together or disjunctor is made; Lamp outer casing adopts imitative brave shape, gives the people novel sensation, is provided with the palisade fin with lamp outer casing body disjunctor at the lamp outer casing back, because the entire mechanism good leak tightness, thereby can prevent to drench with rain; Be positioned at the light fixture plate and be provided with light sensor, a single chip machine controlling circuit connects light sensor, by light sensor perception natural light brightness, when arriving night, then the luminous driving chip of single chip machine controlling circuit control LED lamp is opened LED lamp, street lamp work; When morning at day, at this moment light sensor can be experienced natural daylight, the single chip machine controlling circuit follow procedure is controlled the luminous driving chip of corresponding LED lamp and is closed the corresponding LED lamp that connects, and the LED lamp of lighting is closed, street lamp quits work.The utility model is used for the illumination of highway, street, square, public place of entertainment etc.The utlity model has characteristics such as structure is novel, energy-conservation, good heat dissipation effect.
