Description
Technical field
The utility model relates to a kind of lighting apparatus, and is particularly a kind of by the lighting bulb of light emitting diode as light source.
Background technology
The application of electric light source, thoroughly changed lighting system, since electric light source comes out, multiple light fixtures such as incandescent lamp, fluorescent lamp, Halogen lamp LED once occurred, but these light fixtures all belong to the category of thermal light source, the electric energy of its consumption very major part all is used for heating, luminous again by heat, its shortcoming is that power consumption is big, and luminous efficiency is low, and energy waste is serious.
Along with the appearance of semiconductor light-emitting-diode, and produced a kind of new light sources, it is directly luminous by semiconductor energising back, could be luminous after not needing electric energy is converted into heat energy, but a kind of cold light source.It has the advantages that volume is little, power consumption is low, luminosity is high and luminous efficiency is high, does not just use as lighting source as yet owing to its single volume is little.Even use, also be the illuminator that the most diodes of planar alignment form, and amorphous products is come out, and the lighting bulb of LED do not occur being particularly suitable for as lighting source.
The utility model content
The purpose of this utility model is to provide a kind of led light source lighting bulb, and it is a kind of led light source illuminating product of typing, does not re-use simple planar light source form, has efficient height, brightness height, characteristics that power consumption is little.
Led light source lighting bulb of the present utility model comprises bulb shield, emitting led group and tube face, and bulb shield is connected with tube face, and emitting led group is arranged on the tube face, is positioned at bulb shield.Wherein, emitting led group comprises multi-layer PCB board and most LED, and multi-layer PCB board is along the bulb axially-aligned, and diameter increases from top to bottom gradually, is pyramid and arranges; LED is separately fixed on the multi-layer PCB board, also is pyramid and arranges, and be electrically connected with pcb board; Described emitting led group is electrically connected with lamp socket by the disconnected son of wiring.
Respectively be provided with reflective membrane on the pcb board of above-mentioned described multilayer, and the edge of reflective membrane protrudes in the edge of pcb board, be respectively applied for reflection emitting led send after penetrate light.
The edge of above-mentioned described reflective membrane can upwards bend, and forms the bucket shape structure, to improve reflecting effect.
The top layer of described multi-layer PCB board is evenly laid emitting led, and the LED on all the other each layer pcb boards arranges ringwise, and the diameter of annular is greater than the diameter of its upper strata pcb board.
Above-mentioned described multi-layer PCB board can be two-layer, and corresponding LED also is two-layer.
The top of described bulb shield is lenticular, and the inner cover wall of bulb shield is provided with reflecting coating.
By structure of the present utility model, form a kind of emitting led group of stereoscopic multi-layer, the emitting led number in the unit volume is increased greatly, the light that sends is also strengthened naturally greatly.In conjunction with the reflex of the reflecting coating of the reflective membrane of each emitting led behind and bulb inner wall, penetrate light after effectively having utilized again, improved luminous efficiency greatly.
Description of drawings
Fig. 1 is the part section structural representation of bulb of the present utility model;
Fig. 2 is the plan structure schematic diagram of emitting led group of the present utility model.
The specific embodiment
As shown in Figure 1, led light source lighting bulb of the present utility model is made of tube face 8, bulb shield 1 and emitting led group, and wherein LED group is arranged on the tube face 8, and is electrically connected with tube face 8 by the disconnected son of wiring 9.Bulb shield 1 is then fixedlyed connected with tube face 8, thereby, forms complete bulb with emitting led group cover within it.
As shown in Figure 1 and Figure 2, emitting led group of the present utility model is made of two pcb boards of axially arranging and the LED that is arranged on the pcb board, wherein evenly lays LED 3 on the pcb board 5 of top layer, on lower floor's pcb board 10 then annular LED 3 is set.Wherein the diameter of the pcb board 5 of top layer is less than the diameter of lower floor's pcb board 10, and the annular diameter of the annular LED on lower floor's pcb board 10 also is slightly larger than the diameter of top layer pcb board 5, so that the light of the LED of lower floor can effectively penetrate.
For the light that makes the emitting led all directions of sending can both produce illuminating effect, on top layer pcb board 5, lay one deck reflective membrane 4, the edge with pcb board 5 is given prominence at the edge of this reflective membrane 4, and be the bending shape that upwarps, to form a reflective membrane bucket, before all being reflected into, all directions light that the LED on the top layer pcb board 5 is sent penetrates light.On lower floor's pcb board, lay reflective membrane 11, to penetrate light behind the reflection lower floor annular LED.Simultaneously between two-layer pcb board the vertically disposed reflective membrane 12 of a circle is being set, this reflective membrane 12 is positioned at the inboard of the LED ring that annular is provided with, the light of the LED that is provided with reflective annular.
In addition, fix with fixed leg 7 between the two-layer pcb board, and between two pcb boards, lead 13 is set, to connect power supply.
As shown in Figure 1, the top of this bulb shield 1 is provided with and is lenticular, can be concavees lens as required, also can be convex lens.And the inboard of the wall 2 of bulb shield 1 is provided with reflecting coating 6, is used for reflection ray, increases illuminating effect.
