Description

Protruding spherical LED lamp affixed to the ceiling

Technical field:

The utility model relates to fitting structure, is specially adapted to the lamp affixed to the ceiling on the ceiling.

Background technology:

Illuminator lamp mostly is pendent lamp, fluorescent lamp formula lamp affixed to the ceiling on household, the office space ceiling at present.Pendent lamp takes up space greatly, bring the crowded and inharmonious sense in space for the household of now generally having only 2.7 meters floor heights, and office's ceiling mostly is with lamp and adorns fluorescent lamp in the frame-type, promptly in the flat framework of a metal " door " font, install and fix fluorescent lamp, the fixing rectifier of space mounting in the framework back side or framework.These two kinds of conventional light source light fixture shortcomings are that power consumption is big, does not meet environmental protection and energy saving requirement now.

Present lamp affixed to the ceiling generally by lamp socket, light fixture in " door " font lamp door, lamp door, draw lead, supply convertor is formed, its supply convertor is generally rectifier.

Present LED Lantern Festival can characteristic highlight, but is not applied to the lamp affixed to the ceiling field as yet, and Application and Development LED lamp affixed to the ceiling is to meet present energy-conserving and environment-protective requirement.

Summary of the invention:

The purpose of this utility model is to overcome above-mentioned defective, and a kind of protruding spherical LED lamp affixed to the ceiling is provided.

Scheme of the present utility model is: comprise lamp door, lamp socket, light fixture, draw lead, supply convertor, it is characterized in that lamp door is made up of top board and four horizontal U-type strips, article four, U-type strip is symmetrically distributed in length and breadth, horizontal stripe lower surface is buckled on the upper surface surrounding of square top board on it, lamp socket is the strip wiring board of band jack, light fixture is protruding spherical LED lamp, behind the corresponding jack of wiring board of several uniform LED lamp two wiring inserted links insertions as lamp socket, scolding tin is fixedlyed connected the printed wire on the wiring board with the inserted link end, the vertical inwall of lamp door two vertical U-type strips is implemented to paste by the adhesive-layer and the two wiring board back sides respectively and is connected; Lamp door top board inner surface is connected with implementing to paste by adhesive-layer with the reflection diaphragm of homalographic; The diffusion barrier sheet that frame inner cavity surface such as the hollow square frame upper surface that Cross slat is formed under four U-type strips of lamp door is fixed with are amassed such as is provided with at the rectangular-shaped LGP of spatial form in the cuboid space that lower plane, both sides LED lamp and two horizontal U-type strips surround on diffusion barrier sheet and reflection diaphragm; This LGP is provided with the crown groove of arranging on the wiring board of the corresponding several balls of LED lamp corresponding to the frame of both sides LED lamp, and the protruding ball bulb of protruding spherical LED lamp stretches in this groove; Terminal two electrode points of two wiring boards are connected with power supply changeover device two outputs enforcement circuit by drawing lead, and power supply changeover device two inputs are implemented circuit with external power and are connected.

Advantage of the present utility model is: lamp affixed to the ceiling uses that the brightness of LED lamp is big, fractional energy savings is high, and relatively conventional light source is energy-conservation 60%, radiation such as no ultraviolet light, infrared light, and it is fast not have stroboscopic, flicker free, startup simultaneously.Protruding globular bulb stretches into the LGP respective slot, makes LED lamp light-emitting line all in the LGP internal reflection, and light source is fully used.

The specific embodiment:

Structure of the present utility model comprises lamp door, lamp socket, light fixture, draw lead, supply convertor, it is characterized in that lamp door is made up of top board (3) and four horizontal U-type strips (1), article four, U-type strip (1) is symmetrically distributed in length and breadth, horizontal stripe lower surface is buckled on the upper surface surrounding of square top board (3) on it, lamp socket is the strip wiring board (7) of band jack, light fixture is barcode LED lamp (2), behind the uniform corresponding jack of wiring board (7) of several LED lamp (2) two wiring inserted links insertions as lamp socket, scolding tin is fixedlyed connected the printed wire on the wiring board (7) with the inserted link end, lamp door two vertical U-type strips (1) vertically inwall are connected by adhesive-layer and the enforcement stickup of two wiring boards (7) back side respectively; Lamp door top board (3) inner surface is connected with implementing to paste by adhesive-layer with the reflection diaphragm (4) of homalographic; Four U-type strips of lamp door (1) down the hollow square frame upper surface formed of Cross slat be fixed with and wait the long-pending diffusion barrier sheet (6) of frame inner cavity surface, the rectangular-shaped LGP (5) of spatial form such as in the cuboid space that last lower plane, both sides LED lamps (2) and the two horizontal U-type strips (1) of diffusion barrier sheet (6) and reflection diaphragm (4) surround, be provided with; This LGP (5) is provided with the crown groove of the corresponding several balls of LED lamp (2) that wiring board (7) is gone up arrangement corresponding to the frame of both sides LED lamps (2), and the protruding ball bulb of protruding spherical LED lamp (2) stretches in this groove; Terminal two electrode points of two wiring boards (7) are connected with power supply changeover device two outputs enforcement circuit by drawing lead, and power supply changeover device two inputs are implemented circuit with external power and are connected.
