Abstract

The invention discloses an LED (light-emitting diode) light-emitting device comprising a base, a combined LED light source and a light shade, wherein the LED light-emitting device is characterized in that the combined LED light source comprises a radiator, and a flexible PCB (printed circuit board) equipped with an LED bulb and mounted on the radiator, the radiator is tower-shaped and the flexible PCB corresponds to the unfolded surface of the radiator in shape. Accordingly, the flexible PCB equipped with the LED bulb is bound on the conical radiator by the heat-conducting double-sided adhesive of radiating fins, so as to form a conical light-emitting body. The invention can achieve the 360-degree uniform illumination and better radiating effect.

Description

A kind of LED light-emitting device
Technical field
The present invention relates to a kind of LED light-emitting device, especially a kind of LED 360 degree light-emitting devices.
Background technology
Led light source is long with the life-span, and is pollution-free, and characteristics such as light efficiency height are just progressively replaced current white knowledge lamp and fluorescent light.Products such as LED fluorescent tube, LED street lamp, LED shot-light have occupied certain share on market.But because the lighting angle of LED is little and the reason of heat radiation difficulty, wanting to make 360 degree luminous but is very difficult thing.Ubiquitous in the market all is flat luminous, multifaceted light-emitting or the luminous form of powerful point, and the shortcoming of the light source of this mode is that an area brightness height, light are concentrated, lighting angle is little, light is inhomogeneous etc.
Summary of the invention
It is bigger that the technical problem to be solved in the present invention provides a kind of lighting angle, luminous uniform LED light-emitting device.
The technical solution adopted for the present invention to solve the technical problems is:
The LED light-emitting device, comprise pedestal, combination led light source body, lampshade, it is characterized in that: combination led light source body comprises radiator, the flexible PCB plate of LED lamp pearl is installed, described flexible PCB plate is installed on the radiator, described radiator is a turriform, and the shape of flexible PCB plate is corresponding with the shape on radiator surface.
Radiator is conical; Behind the flexible PCB plate development be shaped as with the radiator unfolded surface after shape corresponding fan-shaped.
LED lamp pearl evenly distributes on the flexible PCB plate.
The flexible PCB plate is installed and is attached on the radiator by the heat sink conducts heat double faced adhesive tape.
Lampshade is an elen shade.
The invention has the beneficial effects as follows: the flexible PCB plate that LED lamp pearl is installed is wrapped on the conical radiator by the heat sink conducts heat double faced adhesive tape, forms conical illuminator, not only realized 360 degree uniformly light-emittings, and radiating effect is better.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the whole schematic views of LED light-emitting device;
Fig. 2 is the whole schematic views of combination led light source body;
Fig. 3 is the expansion view that the fan-shaped pcb board of LED lamp pearl is installed.
The specific embodiment
See figures.1.and.2, a kind of LED light-emitting device provided by the present invention comprises pedestal 1, combination led light source body 2, lampshade 3, on combination led light source body 2 and lampshade 3 mounting bases 1.
Combination led light source body 2 comprises radiator 21, the flexible PCB plate 22 of LED lamp pearl 23 is installed, and flexible PCB plate 22 is attached on the radiator 21 by heat sink conducts heat double faced adhesive tape 24.The shape of radiator 21 of the present invention is preferably taper shape, after flexible PCB plate 22 launches be shaped as with radiator 21 unfolded surfaces after corresponding fan-shaped, LED lamp pearl 23 is evenly distributed on the fan-shaped flexible PCB plate 22.Setting both can realize that 360 degree were luminous uniformly like this, again can be effectively the heat of LED be passed in the conical radiator 21 and went, and played better heat radiating effect.
Radiator 21 be designed to cone and flexible PCB plate be shaped as with the radiator unfolded surface after shape corresponding fan-shaped, be a kind of optimal way of the present invention, be not construed as limiting the invention.
In addition, lampshade of the present invention 3 is preferred elen shade, elen shade can be effectively reduce the string light of LED, to eliminate the injury of LED lamp high light to human eye.
