Detailed description of the invention
In order to further explain technical scheme, below by specific embodiment, the present invention is specifically addressed.
As Fig. 3-1 is to shown in Fig. 3-4, and a kind of LED luminescence component, including a LED illuminator 1 with bidirectional luminescence and for fixing the L-type support 2 of this luminous body.
The LED illuminator 1 of this bidirectional luminescence includes a transparency carrier 11, LED luminescence chip 12 and wavelength conversion layer 13.nullThis transparency carrier 11 is made up of transparent alumina or aluminium nitride ceramics，Material itself has certain thermal conduction characteristic but does not have conductive characteristic，It is just、Anti-surface is respectively the first first type surface 111 and the second first type surface 112，It is provided with the first conducting channel 113 for LED luminescence chip 12 power supply on the first major surface，Described LED luminescence chip 12 arranges on the first major surface 111，And at least some light may pass through the first first type surface 111 and transmits from the second first type surface 112，Therefore LED luminescence chip 12 is more than the light intensity transmitting the second main light emission face from the second first type surface 112 from the first first type surface 111 to the light intensity in extraradial first main light emission face，Described wavelength convert 13 layers is arranged at described light-emitting diode chip for backlight unit 12、On first first type surface 111 and the second first type surface 112，Described wavelength conversion layer 13 at least partly absorbs the light that described light-emitting diode chip for backlight unit 12 is sent，And it is converted into the wavelength of different range，Such as white light etc.；
Described L-type support 2 is made up of the vertical end 200 with thermal conduction characteristic and the transverse end 201 having heat conduction and insulation characterisitic concurrently, described transverse end cross section from top to bottom includes electrode layer, insulating barrier and heat-conducting layer (not shown), this L-type support 2 can be made up of integrated aluminium base, also aluminium base can be used by transverse end 201, and vertical end 200 uses metal heat-conducting material or heat pipe to be jointly spliced to form, , it is provided with breach at the middle part of this support 2 vertical end 200, this breach is U-shaped breach 21, its width is more than or equal to the width of LED luminescence chip 12 in LED illuminator 1, and less than 11 width of transparency carrier, guarantee that light can outwards carry out light radiation through this breach；Electrode layer in this L-type support 2 transverse end 201 is provided with the second conducting channel 114；Transparency carrier 11 in described LED illuminator 1 is interfixed with L-type support 2 vertical end 200 by weld layer 22, the rack body of the most U-shaped breach 21 both sides, and makes its luminescence chip 12 be correspondingly arranged on this U-shaped breach 21；
Minimum range H between weld layer 22 and the first conducting channel 113 on the first first type surface 111 is more than the corresponding standard creep age distance based on corresponding safe voltage simultaneously, because the scolding tin of weld layer 22 belongs to easy conductive material, transparency carrier 11 belongs to isolation material, when the distance of the first conducting channel 113 to weld layer 22 is more than the standard creep age distance of correspondence based on corresponding safe voltage, it is ensured that its voltage endurance that insulate.
Simultaneously because carry out going here and there or in parallel by the wire 115 of shell parcel insulating barrier between first conducting channel the 113, second conducting channel 114, it is ensured that wire 115, in galvanization, will not destroy whole group of luminescence component insulation voltage endurance；
And first conducting channel the 113, second conducting channel 114 respectively to the vertical end 200 of L-type support or aluminum transverse end 201 heat-conducting layer minimum range H be all higher than the standard creep age distance of correspondence based on corresponding safe voltage, because the heat-conducting layer of the vertical end of L-type support 200 and transverse end 201 is electric conductor, first conducting channel the 113, second conducting channel 114 had enough safety creepage distances between above-mentioned electric conductor, meeting the requirement that the insulation of this luminescence component is pressure, the electric heating simultaneously realizing product separates；
The transverse end of this L-type support 2 can have additional several unidirection luminous bodies 23 simultaneously, for increasing the light intensity of the transverse end (horizontal ends) of this luminescence component.
nullAs shown in Figure 4，The figure shows the embodiment applying to bulb lamp of this luminescence component，This bulb lamp includes lamp adapter assembly 31、Radiating seat 32、Lampshade 33 and two groups of luminescence components 34 using technical scheme above to make，The transverse end 3412 of the L-type support 341 of these two groups of luminescence components 34 is side by side，And its vertical end 3411 is oppositely disposed on radiating seat 32，And the first first type surface 342 of two groups of luminescence components is oppositely arranged，Transverse end 3412 in L-type support 341 is provided with several unidirection luminous LED illuminator 35，Use 2 groups of luminescence components that seat mode is configured，Owing to the first first type surface 342 is oppositely arranged，LED luminescence component 34 is near lampshade 33，And first main light emission face 342 towards lampshade 33 position，I.e.，It is perpendicular to the air line distance of the first first type surface 342 to lampshade 33 less than the air line distance being perpendicular to the second first type surface 343 to lampshade 33，Therefore bulb lamp side brightness and visual angle are added，Some unidirection luminous LED illuminator 35 at L-type support transverse end simultaneously，Add the light intensity of the transverse end (horizontal ends) of this light fixture，Achieve the lighting system of the all-round light of this bulb lamp；Simultaneously because L-type support can use the integrated aluminium base of excellent in heat dissipation effect or is heat pipe by vertical end 3411, the composition (shown by diagram is that integrated L-type aluminium base is as embodiment) that transverse end 3412 is spliced jointly for aluminium base, can by the heat of LED luminescence chip or LED illuminator by by L-type aluminium base 341 along radiating seat 32 to external diffusion, add the radiating efficiency of LED luminescence chip, improve the service life of luminescence component.
nullAs shown in Figure 5，The figure shows the embodiment applying to candle lamp of this luminescence component，Its basic structure is basically identical with the ball bulb lamp structure shown in Fig. 4，The simply transverse end of the L-type support 341 of two groups of LED luminescence components 34 be not provided with unidirection luminous LED illuminator，This L-type support 341 uses the heat pipe 3411 of vertical end to be jointly spliced to form with the aluminium base 3412 of transverse end simultaneously，Although two groups of LED luminescence components 34 are also to be arranged side by side on radiating seat 32 and its first first type surface 342 is oppositely arranged，But the vertical end of the L-type support 341 of two groups of luminescence components is arranged side by side and in line，And it should be noted that the height of L-type support 341 vertical end 3411 is the highest，The irradiating angle of the LED luminescence chip being arranged on the U-shaped breach of L-type support is the biggest，The range of exposures of whole group of light fixture is the biggest.
Above-described embodiment and diagram the product form of the non-limiting present invention and style, suitably change that it is done by any person of an ordinary skill in the technical field and modifying, all should be regarded as the patent category without departing from the present invention.
