Abstract

The utility model discloses an LED street lamp with an adjustable illumination angle, which comprises a lamp holder and a plurality of LED lamps, wherein the LED lamps are mounted on the lamp holder, each LED lamp comprises a reflecting plate, and each reflecting plate is fixed on the lamp holder and positioned beside the LED lamp. The LED street lamp adjusts the optical design of C90 to C270 angle according to the width of the road surface and the customer's need for uniformity of the road surface illumination, achieves the reasonable distribution of light intensity at the angle, and ensures the uniform illumination and the reasonable illumination distribution of the desired road surface. The illumination on the specified road surface is uniform and highly-efficient, and the illumination outside the specified road surface is extremely low, thereby achieving the purposes of saving energy and reducing light pollution.

Description

The LED street lamp that irradiating angle is adjustable

Technical field

The utility model relates to the adjustable LED street lamp of a kind of irradiating angle.

Background technology

Now existing several different methods can solve the optical design of LED street lamp between C0-C180, but the distribution at C90 and C270 equal angles light has problems, cause the light source on roadside and limit, room out of proportion, both wasted light source under the valuable lamp, cause the light pollution under the room, reduced uniformity of illuminance again.

The utility model content

The purpose of this utility model provides the adjustable LED street lamp of a kind of irradiating angle, and is simple in structure, the light angle that can regulate the LED lamp.

For achieving the above object, technical scheme provided by the utility model is: the LED street lamp that a kind of irradiating angle is adjustable includes lamp socket and some LED lamps, the LED lamp is installed on the lamp socket, this LED street lamp also includes reflecting plate, and described reflecting plate is fixedly connected on the lamp socket, is positioned at LED lamp next door.

Described reflecting plate is welded on the lamp socket.

Described reflecting plate includes first reflecting part, second reflecting part and the fixed part of fixedlying connected with lamp socket, and the described fixed part and second reflecting part are fixedly connected on the two ends of first reflecting part respectively; Intersect in the front of the described fixed part and first reflecting part is acute angle, and it is the obtuse angle that the reverse side of described second reflecting part and first reflecting part intersects.

Described fixed part, first reflecting part and second reflecting part are structure as a whole.

The advantage that the utlity model has: this product is according to the requirement of width and client's road pavement uniformity of illuminance on road surface, optical design to the C90-C270 angle is adjusted, reasonably distribute the light intensity of this angle, make that the illumination on required road surface is even, distribute rationally.Illumination on the regulation road surface is even, and efficient improves, and the illumination outside the regulation road surface is extremely low, thereby reaches purpose energy-conservation and the minimizing light pollution.

Description of drawings:

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation of reflecting plate;

Fig. 3 is the left view of Fig. 2.

The specific embodiment:

The LED street lamp that a kind of irradiating angle as shown in Figure 1 is adjustable includes lamp socket 3, LED lamp 2 and reflecting plate 1, and LED lamp 2 is installed on the lamp socket 3, and reflecting plate 1 is fixedly connected on the lamp socket 3, is positioned at LED lamp 2 next doors.

Reflecting plate 1 can be fixed on the lamp socket 3 by welding, riveted joint, bolt connection or bonding way.

Shown in Fig. 2 and 3, reflecting plate 1 includes first reflecting part 12, second reflecting part 13 and the fixed part 11 of fixedlying connected with lamp socket, and the fixed part 11 and second reflecting part 13 are fixedly connected on the two ends of first reflecting part 12 respectively; Intersect in the front of the fixed part 11 and first reflecting part 12 is sharp angle, and it is obtuse angles beta that the reverse side of second reflecting part 13 and first reflecting part 12 intersects.

For easy to operate, fixed part 11, first reflecting part 12 and second reflecting part 13 can be made as integrative-structure.

The utility model is by all adding a reflection thin plate 1 (reflection bar is generally aluminum) in a side of each row LED lamp 2, passing through sky light, adjust the light distribution in the C90-C270 angle, make that the light distribution on required road surface is evenly reasonable, improve illuminating effect, thereby lower energy resource consumption.

The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, though the utility model discloses as above with preferred embodiment, yet be not in order to limit the utility model, any those skilled in the art, in not breaking away from the technical solutions of the utility model scope, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solutions of the utility model, according to technical spirit of the present utility model to any simple modification that above embodiment did, equivalent variations and modification all still belong in the scope of technical solutions of the utility model.
