Abstract
The utility model provides a light emitting diode (LED) street lamp, which mainly solves the problems of low connection intensity and unsafe use of the existing LED street lamp and comprises an LED light source, an LED power supply, a street lamp casing and a street lamp lampshade, wherein the street lamp lampshade is arranged at the outer side of the LED light source and is connected with the light source side of the street lamp casing, a heat radiator is arranged on the back side of the street lamp casing, a groove is formed in the middle of the heat radiator, the shape of the cross section of the groove is matched with a lamp post of the street lamp, a press plate is also arranged at the back side of the street lamp casing, a cavity formed between the press plate and the groove is used for inserting the lamp post of the street lamp, the press plate is fixedly connected with the lamp street casing through a locking device, at least one weight reducing hole is formed on the press plate, and the flanging treatment is carried out on the circumference of the weight reducing hole.
Description
Technical field
The present invention relates to a kind of LED street lamp, belong to the LED lighting field.
Background technology
What high-power LED street lamp was different with conventional high-pressure mercury lamp street lamp is, the efficient white light-emitting diodes that the light source of high-power LED street lamp adopts low-voltage DC supply, synthesized by GaN based power type blue-ray LED and yellow fluorescent powder, have efficient, safety, energy-saving and environmental protection, distinct advantages such as the life-span is long, response speed is fast, colour rendering index height, can be widely used in city illumination.High-power LED street lamp effectively reduces windage and weight, alleviates the load of lamp stand, strengthens safety coefficient.
Since high-power LED street lamp when work caloric value big, therefore need the bigger heat abstractor of assembling to satisfy its heat radiation requirement, cause the increase of himself weight like this; Existing high-power LED street lamp all is provided with jockey by street lamp housing side and is connected with the lamp stand end, and the intensity of this mode is lower, and long-term outwork may cause street lamp directly to come off from lamp stand, and what cause the accident frees.
Summary of the invention
The invention provides a kind of LED street lamp, it is low mainly to have solved existing LED street lamp bonding strength, uses unsafe problem.
Concrete technical solution of the present invention is as follows:
This LED street lamp, comprise led light source, LED power supply, street lamp housing and street lamp lampshade, described street lamp lampshade is arranged at the led light source outside and is connected with street lamp housing light source side, street lamp housing dorsal part is provided with heat abstractor, the centre of heat abstractor is provided with groove, and the shape and the street lamp post of groove cross section are suitable; Described street lamp housing dorsal part also is provided with pressing plate, and the cavity that forms between pressing plate and the groove is used to insert street lamp post, and pressing plate is fixedlyed connected with the street lamp housing by locking device; Described pressing plate is provided with at least one lightening hole, does flange around the lightening hole and handles.
General pressing plate or the housing of selecting through the aluminium alloy compression casting moulding on electrostatic spraying surface of above-mentioned pressing plate and/or street lamp housing.
The invention has the advantages that:
Owing to adopted the street lamp pressing plate and on the street lamp housing, be provided with groove, will connect center of gravity and be transferred to lamp stand bar portion, road lamp body is equivalent to be socketed on the lamp stand, has increased lifting surface area, has increased bonding strength; Simultaneously, owing to increased groove, alleviated the weight of street lamp and do not influenced radiating effect.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described in detail:
This LED street lamp comprises led light source, LED power supply 1, street lamp housing 4 and street lamp lampshade 3, described street lamp lampshade 3 is arranged at the led light source outside and is connected with street lamp housing 4 light source side, street lamp housing 4 dorsal parts are provided with heat abstractor, the centre of heat abstractor is provided with groove 2, and the shape and the street lamp post of groove 2 cross sections are suitable; Street lamp housing 4 dorsal parts also are provided with pressing plate 5, and the cavity that forms between pressing plate 5 and the groove 2 is used to insert street lamp post, and pressing plate 5 is fixedlyed connected with street lamp housing 4 by locking device, and general the employing is threaded or clamping; Pressing plate 5 is provided with at least one lightening hole, does flange around the lightening hole and handles, and flange is handled the intensity that has increased pressing plate 5, and long-term heavy burden can not deform.This pressing plate 5 can select through the aluminium alloy compression casting moulding on electrostatic spraying surface pressing plate 5.
Owing to adopted street lamp pressing plate 5 and on street lamp housing 4, be provided with groove 2, will connect center of gravity and be transferred to lamp stand bar portion, road lamp body is equivalent to be socketed on the lamp stand, has increased lifting surface area, has increased bonding strength; Simultaneously, owing to increased groove, alleviated the weight of street lamp and do not influenced radiating effect.
Claims (2)
1. LED street lamp, comprise led light source, LED power supply, street lamp housing and street lamp lampshade, described street lamp lampshade is arranged at the led light source outside and is connected with street lamp housing light source side, street lamp housing dorsal part is provided with heat abstractor, it is characterized in that: the centre of described heat abstractor is provided with groove, and the shape and the street lamp post of groove cross section are suitable; Described street lamp housing dorsal part also is provided with pressing plate, and the cavity that forms between pressing plate and the groove is used to insert street lamp post, and pressing plate is fixedlyed connected with the street lamp housing by locking device; Described pressing plate is provided with at least one lightening hole, does flange around the lightening hole and handles.
