Abstract

The utility model discloses an LED (light emitting diode) ceiling lamp with a high lighting effect. The LED ceiling lamp with the high lighting effect comprises a bottom plate, a lampshade, a lamp holder, LED lamps and a driving power supply, wherein the lampshade is screwed on the bottom plate; the center part of the bottom plate is upwards extruded to form a cone frustum; an upward hollow part is formed on the bottom surface of the bottom plate; the lamp holder is connected into the hollow part of the bottom plate; the driving power supply is arranged in the lamp holder; the LED lamps are evenly distributed on the upper surface of the bottom plate and the top surface and the conical surface of the cone frustum; annular reflective sheeting is arranged around the inner side of the edge of the bottom plate; the reflecting surface of the reflective sheeting is vertical to the plane of the bottom plate; the center area on the upper surface of the bottom plate is provided with the LED lamp to enhance the luminance of the central area of the ceiling lamp; according to the LED lamps on the conical surface of the cone frustum, the illumination luminance, except the central area, of the ceiling lamp, is enhanced; meanwhile, the illumination luminance of the central area of the ceiling lamp is further enhanced by the reflection of the reflective sheeting on the surrounding edge of the bottom plate.

Description

High light efficiency LED lamp affixed to the ceiling

Technical field

The utility model relates to a kind of LED light fixture, specifically refers to a kind of high light efficiency LED lamp affixed to the ceiling.

Background technology

LED lamp affixed to the ceiling is applicable to the long-time illumination of family and various public places, and its profile feature is that light fixture top is more flat, can install near roof, similarly is to be adsorbed on roof, good decorating effect.The driving power of tradition lamp affixed to the ceiling is loaded on the center chassis in lamp body, and due to the restriction of locus, LED lamp is not established in center chassis region, and therefore brightness of illumination and the uniformity are all affected to a certain extent; In addition, it is by metope pre-embedded setscrew that traditional lamp affixed to the ceiling is installed, then be fixed, when family is used, dismounting comparatively bothers.

Utility model content

The purpose of this utility model is to provide a kind of high light efficiency, simple LED lamp affixed to the ceiling is installed.

For achieving the above object, the technical solution adopted in the utility model is as follows:

A kind of high light efficiency LED lamp affixed to the ceiling, comprises chassis, lampshade, lamp holder, LED lamp and driving power; Described lampshade is rotatably connected on chassis; Convex one-tenth one frustum of a cone of central part on described chassis, makes the bottom surface on chassis form a depressed part upwards, and described lamp holder is connected in the described depressed part on chassis, and described driving power is loaded in lamp holder; Described LED lamp is laid in end face and the conical surface of the upper surface on described chassis, the described frustum of a cone equably, and the inner side of described chassis edge is arranged with the reflective sheeting of an annular, and the reflective surface of this reflective sheeting is perpendicular to chassis plane.

The beneficial effects of the utility model are: the driving power of this lamp affixed to the ceiling is loaded in lamp holder, and the central area of chassis upper surface just can mounted LED lamp, has strengthened the brightness of lamp affixed to the ceiling central area; And LED lamp has not only strengthened the illumination brightness of lamp affixed to the ceiling except central area on the frustum of a cone conical surface, meanwhile, by the reflection of chassis periphery reflective sheeting, further strengthen the illumination brightness of lamp affixed to the ceiling central area.This lamp affixed to the ceiling adopts lamp holder to install, and only need revolve lamp holder when dismounting, has exempted complicated disassemble and assemble work; The design of upwards caving in chassis, while making to adopt lamp holder mounting means, the gap of chassis and metope is not too large.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, the utility model is described further:

Fig. 1 is the structural profile schematic diagram of the utility model high light efficiency LED lamp affixed to the ceiling;

Fig. 2 is chassis and the LED lamp mounting structure top view of lamp affixed to the ceiling in Fig. 1.

The specific embodiment

With reference to figure 1 and Fig. 2, a kind of high light efficiency LED lamp affixed to the ceiling, comprises chassis 1, lampshade 2, lamp holder 3, LED lamp 4 and driving power 5; Described lampshade 2 is rotatably connected on chassis 1; Convex one-tenth one frustum of a cone 11 of central part on described chassis 1, makes the bottom surface on chassis 1 form a depressed part upwards, and described lamp holder 3 is connected in the described depressed part on chassis 1, and described driving power 5 is loaded in lamp holder 3; Described LED lamp 4 is laid in the upper surface on described chassis 1, end face and the conical surface of the described frustum of a cone 11 equably, and in present embodiment, the LED lamp 4 of chassis 1 upper surface all distributes in the form of a ring.The inner side at 1 edge, described chassis is arranged with the reflective sheeting 6 of an annular, and the reflective surface of this reflective sheeting 6 is perpendicular to chassis 1 plane.The driving power 5 of this lamp affixed to the ceiling is loaded in lamp holder 3, the central area of chassis 1 upper surface just can mounted LED lamp, strengthen the brightness of lamp affixed to the ceiling central area, and LED lamp has not only strengthened the illumination brightness of lamp affixed to the ceiling except central area on the frustum of a cone 11 conical surfaces, simultaneously, by the reflection of chassis periphery reflective sheeting 6, further strengthen the illumination brightness of lamp affixed to the ceiling central area.This lamp affixed to the ceiling adopts lamp holder to install, and only need revolve lamp holder when dismounting, has exempted complicated disassemble and assemble work; The design of upwards caving in chassis 1, while making to adopt lamp holder mounting means, chassis 1 is not too large with the gap of metope.

Above embodiment is just explanation rather than restriction the utility model, and the equivalence of doing according to the method described in the utility model patent claim therefore all changes or modifies, and is included in the utility model patent claim.

Claims

1. high light efficiency LED lamp affixed to the ceiling, is characterized in that: comprise chassis, lampshade, lamp holder, LED lamp and driving power; Described lampshade is rotatably connected on chassis; Convex one-tenth one frustum of a cone of central part on described chassis, makes the bottom surface on chassis form a depressed part upwards, and described lamp holder is connected in the described depressed part on chassis, and described driving power is loaded in lamp holder; Described LED lamp is laid in end face and the conical surface of the upper surface on described chassis, the described frustum of a cone equably, and the inner side of described chassis edge is arranged with the reflective sheeting of an annular, and the reflective surface of this reflective sheeting is perpendicular to chassis plane.
