Abstract
The utility model relates to the street lamp technical field, in particular to an LED street lamp which comprises a housing and a transparent cover. A mounting plate is arranged in the housing; a metal baseplate is arranged on the inner wall of the mounting plate; and an LED array, a control circuit, radiating fins and a photoresistor are arranged on the metal baseplate. A single-chip light source is formed through mounting the LED array on the metal baseplate, so that the disassembly and the installation of the LED street lamp are more convenient; the control circuit and the photoresistor are cooperated with each other for use, so that the use efficiency of the street lamp is greatly improved; and the radiating fins can give off heat with high efficiency, so that the heat radiating efficiency is improved and the service life of the LED is prolonged.
Description
Technical field
The utility model relates to the street lamp technical field, especially a kind of LED street lamp.
Background technology
LED is used for highlight illumination, by people are pursued.Its long service life, power saving, operating voltage is low, security good, will progressively replace existing illuminations, and it has advantages such as high electric energy interest rate and shock resistance are good simultaneously.There are some technological difficulties in the LED street lamp of prior art, and for example, LED assembly complexity is unfavorable for the dismounting and change of lamp holder; Radiating effect is not good, can cause LED to produce light decay, influences the service life of LED street lamp; Luminous efficiency is low, can not give full play to the advantage of LED street lamp, influences operating efficiency.Simultaneously, existing LED street lamp is generally all only artificially controlled by control circuit, can not accurately and timely be passerby's illumination, and the service efficiency utmost point is waited to improve.
The utility model content
Be difficult for dismounting and change and the low deficiency of service efficiency in order to overcome transitional street lamps, the utility model provides a kind of LED street lamp.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of LED street lamp, comprise housing and translucent cover, installing plate is located in the housing, is provided with metal substrate at the inwall of installing plate, and metal substrate is provided with LED light emitting diode matrix, control circuit, fin and photo resistance.
According to another embodiment of the present utility model, comprise that further described metal substrate is a printed circuit board (PCB).
According to another embodiment of the present utility model, comprise that further described metal substrate number is 3-5.
The beneficial effects of the utility model are, by the LED light emitting diode matrix is installed on the metal substrate, formed the monolithic light source, make that removing and installing of LED street lamp is more convenient, described control circuit and photo resistance are used, and make the service efficiency of this street lamp improve greatly, and fin is high efficiency to distribute heat, improve radiating efficiency, prolonged the service life of LED light emitting diode.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
1. housings among the figure, 2. translucent cover, 3. installing plate, 4. metal substrate, 5.LED light emitting diode matrix, 6. control circuit, 7. fin, 8. photo resistance.
The specific embodiment
With preferred embodiment the utility model is described in further detail in conjunction with the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As Fig. 1 is structural representation of the present utility model, a kind of LED street lamp, comprise housing 1 and translucent cover 2, installing plate 3 is located in the housing 1, inwall at installing plate 3 is provided with metal substrate 4, and metal substrate 4 is provided with LED light emitting diode matrix 5, control circuit 6, fin 7 and photo resistance 8. described metal substrates 4 and is printed circuit board (PCB). and described metal substrate 4 numbers are 3-5.
LED light emitting diode matrix 5, control circuit 6, fin 7 and photo resistance 8 are installed on metal substrate 4, wherein control circuit 6 and photo resistance 8 are used, when arriving night, can open the LED street lamp by control circuit 6, also can open the LED street lamp by photo resistance 8, preestablished the opening time for 6 li at control circuit, if the colour of sky is very dark when the opening time does not arrive, it is luminous then can to start the LED street lamp by photo resistance 8, improve the service efficiency of LED street lamp like this, also made things convenient for people's life.Under the normality, by the opening and closing of control circuit 6 by the time control LED lamp of setting, photo resistance 8 auxiliary control circuits 6 are controlled the opening and closing of LED street lamp.
The LED light emitting diode can produce a large amount of heats in luminescence process, accumulate in the translucent cover 2, and the speed of distributing is extremely slow, and by the fin of setting up 7, the heat around can disperseing fast makes the LED light emitting diode reduce light decay, improves service efficiency.The number of metal substrate 4 is preferably 3, and each metal substrate 4 has formed a monolithic light source, is convenient to install and change.This LED street lamp integrates multiple advantage, has prolonged its service life greatly, has improved operating efficiency.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
