Abstract

The invention discloses an LED projection lamp, which comprises a lamp socket, a lamp arm arranged on the lamp socket, a reflector lamp cup arranged on the lamp arm, a driving circuit board and an LED light source arranged in the reflector lamp cup. The lamp socket is a hollow cavity having a hole on the bottom; two stand bars on a first U-shaped lamp arm are hinged on left and right walls of the lamp socket; a second U-shaped lamp arm is fixed on the vertical direction of the first U-shaped lamp arm; and two stand bars on the second U-shaped lamp arm are hinged with the reflector lamp cup. Through the hinged structure of the lamp arm, the lamp cup can freely swing and turn at eight degrees of freedom. The lamp is characterized by simple structure, low manufacturing cost, flexible regulation, excellent commonality, and the like. The lamp is widely applied to various ceiling lamps and indoor interior decoration lamps.

Description

A kind of LED projecting lamp

Technical field:

The present invention relates to the field of interior decoration lighting, particularly a kind of projecting lamp that changes irradiating angle.

Background technology:

At present, common interior decoration Ceiling light or shot-light, for realizing to change irradiating angle, its structure adopts similar gyrostatic pair of change socket join structure mostly, for this structure, although the irradiating angle of light fixture can be regulated as required, but its shortcoming is: 1, fitting structure complexity, assembling inconvenience, complex manufacturing, production cost height, 2, the regulation and control trouble is installed, the poor accuracy of adjustment, and the mechanical hum that produces is big.

Summary of the invention:

Technical problem to be solved by this invention is the defective that overcomes prior art, provide a kind of simple in structure, production cost is low, adjust easy flexibly, the LED projecting lamp of advantage such as versatility is good.

The technical solution adopted for the present invention to solve the technical problems is: a kind of LED projecting lamp, include lamp socket, be loaded on the arm on the lamp socket, be loaded on the reflection Lamp cup on the arm, be loaded on drive circuit board and led light source in the reflection Lamp cup, described lamp socket is the hollow cavity of below perforate, and two legs on the described first U-shaped arm are articulated in lamp socket left and right sides wall, be connected with the second U-shaped arm on the vertical direction of the first U-shaped arm, two legs on the second U-shaped arm are hinged with the reflection Lamp cup.

At above-mentioned LED projecting lamp, two legs of the described first U-shaped arm are hinged by rivet and Lamp cup left and right sides wall, and the second U-shaped leg is hinged with two legs of reflection Lamp cup bottom surface by rivet.

Prior art is compared relatively, and the present invention has following advantage: 1, simple in structure, compact; 2, the accessory production technology is simple, reduces production costs greatly; 3, the swing Lamp cup can be realized the break-in adjustment in eight orientation, adjusts easy to be flexible; 4, versatility is good, can be widely used in various Ceiling lights and interior decoration shot-light.
