The specific embodiment
Fig. 2 is the schematic diagram of the light supply apparatus of the utility model one embodiment, and Fig. 3 is the schematic diagram of the leaded light post of Fig. 2.Please refer to Fig. 2 and Fig. 3, the light supply apparatus 200 of present embodiment comprises a leaded light post 210, a plurality of reflecting layer 220 and one first light source 230.Leaded light post 210 have one first relative end face 212 and one second end face 214 and be connected in first end face 212 and second end face 214 between a side 216 and a plurality of sides 218, wherein side 216 is an exiting surface.At least one of them is provided with a plurality of light diffusion patterned 219 in side 218.Reflecting layer 220 is to be disposed on the side 218.First light source 230 is to be disposed at first end face, 212 sides, and the light 232 that first light source 230 is provided is via first end face, 212 incident leaded light posts 210 and 216 outgoing from the side.
In the above-mentioned light supply apparatus 200, reflecting layer 220 can be reflectance coating or reflecting element, as speculum.In addition, also can be provided with a reflecting layer 220 on second end face 214.In the present embodiment, leaded light post 210 is a quadrangular prism, and side 216 and side 218 are all the plane.In addition, first light source 230 for example is a light emitting diode, and the quantity of light emitting diode can be one or more.
In the present embodiment, owing to all dispose a reflecting layer 220 on second end face 214 and each side 218, so light 232 can reflect between these reflecting layer 220 behind first end face, 212 incident leaded light posts 210, and 216 outgoing from the side, to form the lighting pattern of strip.In addition, light diffusion patterned 219 is to be used for making light 232 diffusion light 232.Light diffusion patterned 219 can be groove, printing net-point or coarse structure, and its further groove for example is V-type indentation (V-cut).In addition, side 216 is a rectangle plane, and the length of side 216 and widely be respectively L1 and L2, and 1≤L1/L2≤2000, preferably 5≤L1/L2≤200.
Because the light 232 that the leaded light post 210 of this enforcement can make first light source 230 be sent forms the lighting pattern of a strip after 216 outgoing of side.Need use a plurality of light sources compared to prior art, light supply apparatus 200 of the present utility model only needs one first light source 230 that the lighting pattern of strip can be provided, and therefore can save production cost.In addition, because quantity of light source is less, so light supply apparatus 200 is saved the energy when operating.
What deserves to be mentioned is, in the utility model, can adjust the light intensity distributions of lighting pattern by changing spacing between adjacent two light diffusion patterned 219.For instance, because behind the light 232 incident leaded light posts 210, more the intensity near the light 232 of first end face 212 is stronger, and more near the intensity of the light 232 of second end face 214 more a little less than, so can cause the brightness of lighting pattern more inhomogeneous.Therefore, present embodiment proposes a kind of leaded light post to improve this phenomenon.Please refer to Fig. 4, can improve the more uneven phenomenon of brightness of above-mentioned lighting pattern by adjusting the spacing between adjacent two light diffusion patterned 219 on the same reflecting surface 218 in the present embodiment.Particularly, in leaded light post 210a, near the spacing of first end face 212 (promptly near first light source 230) greater than away from the spacing of first end face 212 (promptly than away from first light source 230), also be space D 1＞D2＞D3＞D4＞D5.Because it is littler away from the spacing between adjacent two light diffusion patterned 219 of first end face 212, so more the light 232 away from first end face 212 is passed to light diffusion patterned 219 more easily, and then, so can improve the more uneven problem of brightness of lighting pattern by diffusion patterned 219 diffusion and 216 outgoing of light from the side.
Be noted that, though the spacing between adjacent two light diffusion patterned 219 of above-mentioned adjustment is that the utility model also can make the light intensity distributions of lighting pattern conform to required by the spacing of adjusting between adjacent two light diffusion patterned 219 for the light intensity distributions that makes lighting pattern is comparatively even.
