The specific embodiment
The invention provides a kind of dazzle-free LED lighting.This light fixture comprises pedestal, LED light-emitting substrate, LED and the Transparent lamp shade made from materials such as PC and PMMA.Wherein, the LED light-emitting substrate is fixed on the pedestal, and LED is arranged on the LED light-emitting substrate, and Transparent lamp shade covers on LED light-emitting substrate top and is fixed on the pedestal.It is the lens arra of image-generating unit that the Transparent lamp shade surface arrangement has with the lenslet unit.
First embodiment of the present invention is referring to Fig. 1 to Fig. 4.Fig. 4 is the decomposition texture schematic diagram of embodiment among Fig. 1.In this example, the present invention is made of lampshade 3 and lamp socket 4; Wherein, lamp socket 4 comprises that LED light-emitting substrate 40, pedestal 41, radiator 2, power supply 43 and lamp holder 42 constitute.
Spherical Transparent lamp shade 3 covers on the LED light-emitting substrate 40 of lamp socket 4.LED light-emitting substrate 40 is fixed on the pedestal 41, and its outer surface wraps up with radiator 2.Wherein the spherical crown top area of Transparent lamp shade 3 has the hexagon lenslet array 30 that the lenslet unit by the hexagon pit constitutes.The strip slot lens arra 31 that is made of the lenslet unit along the strip slot of spherical crown warp direction is arranged below hexagon lenslet array 30.
Wherein the structure of radiator is referring to shown in Figure 3.There is radiator to be fixed on the base outer wall.Radiator comprises tubular metallic sheath 21 and " T " font heat radiating fin 20 that contacts with base outer wall." T " font heat radiating fin 20 forms annular array on metallic sheath 21.Curved " T " word horizontal edge 200 outer surfaces of " T " font heat radiating fin 20 are provided with bar shaped radiation tooth 202, " T " word vertical edge 201 of " T " font heat radiating fin is connected on the metallic sheath 21, and the junction of " T " font heat radiating fin 20 and metallic sheath 21 is formed on the groove 203 of " T " word vertical edge 201 both sides.Spherical crown bottom at Transparent lamp shade 3 is provided with the gear shaping 32 that supplies insertion groove 203.
The example structure of another kind of profile of the present invention is referring to Fig. 5.The shape that has changed radiator among the figure is different from the profile of the foregoing description.The other parts structure is with above-mentioned embodiment.Among Fig. 5, the heat radiating fin that has sheet to erect on the radiator 2, Transparent lamp shade is fastened on the lamp socket by tight fit.
Invention characteristics of the present invention are the improvement to Transparent lamp shade.Wherein the lens arra on the Transparent lamp shade can adopt various ways.
Referring to Fig. 6, evenly be furnished with the little concavees lens of hexagon unit on the whole Transparent lamp shade inner surface, form the little concavees lens array of hexagon.Its image-forming principle shown in arrow among the figure, the direction of arrow signal light.The light that LED sends, in the inboard picture point that forms of each little concave lens, several little concavees lens then can form several picture points.So several led light sources on the LED light-emitting substrate form numerous picture point on Transparent lamp shade, so whole Transparent lamp shade intuitively seems to be exactly a big area source.The eyes that this mode that LED light is disperseed can not stimulate the people, the light of generation is soft many than prior art.In Fig. 6, the bottom of Transparent lamp shade is provided with interface arrangment, is used for Transparent lamp shade is fixed on lamp socket.
As shown in Figure 7, evenly be furnished with the little convex lens of hexagon unit on the whole Transparent lamp shade inner surface, form the little convex lens array of hexagon.This convex lens can form the picture point of assembling in the bright dipping side of convex lens.Several little convex lens then can form several picture points.So several led light sources on the LED light-emitting substrate form numerous picture point on Transparent lamp shade, so whole Transparent lamp shade intuitively seems to be exactly a big area source.The same with said structure, eyes see that this light fixture can dazzle and dazzling yet.
Referring to Fig. 8, the lenslet unit in the Transparent lamp shade of the present invention is the strip slot along the spherical crown warp direction.This strip slot is a kind of concavees lens structure of bar shaped, and it also can form some picture points on the Transparent lamp shade surface, makes Transparent lamp shade become one and looks dazzle-free area source.
Referring to Fig. 9, the lenslet unit in the Transparent lamp shade of the present invention is the strip slot along the spherical crown warp direction.This strip slot is a kind of convex lens structures of bar shaped, and it also can form some picture points on the Transparent lamp shade surface, makes Transparent lamp shade become one and looks dazzle-free area source.
Lenslet unit further in the Transparent lamp shade of the present invention is square lenslet, and as shown in figure 13, square lenslet forms sphere of movements for the elephants shape array.Certainly, this square lenslet can also be " product " font is staggered.
Transparent lamp shade of the present invention in addition can also adopt the described structure as Figure 10 to Figure 12.Wherein, Figure 10 is that Transparent lamp shade of the present invention is the structure chart of arch body.Figure 11 is along C-C direction structure schematic diagram among Figure 10.Figure 12 is along D-D direction structure schematic diagram among Figure 11.Transparent lamp shade is the body of arch, and its surface is provided with the hexagon lenslet array that is made of hexagon lenslet unit.Lenslet shown in the figure is concavees lens, also can substitute for convex lens.Lenslet array involved in the present invention also can be located at the outer surface of Transparent lamp shade, enters on the lenslet that is located at the lampshade outer surface in order to prevent dust, can add the dust cover of layer of transparent at the outer surface of lens separately.
Referring to Figure 14, Figure 14 is the upward view that the lampshade of annular array is formed in the lenslet unit.Scheming medium and small lens unit is approximate pentagon lens unit, and a plurality of lenslets unit is linked to be a circle and forms a circle annulus, wraps up layer by layer in the form of a ring from inside to outside, forms a kind of annular array.The lenslet cell configuration that forms this annular array can be not only the class pentagon among Figure 14, can also be the lenslet unit of other shape.
The present invention is by being provided with lens arra on Transparent lamp shade, the picture point that makes the LED spot light become to dwindle, but meanwhile, scioptics array LED spot light forms the picture of numerous LED spot light, the interlaced stack of the picture of numerous LED spot light, LED luminous point diffusion is come and increased light-emitting area, form uniform LED area source, thereby dazzling dazzle is controlled effectively.Because the numerous picture point that lens arra produces the structure member virtualization in the light fixture, has been covered inaesthetic internal structure, thereby has been beautified the outward appearance of light fixture.
