Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
For above-mentioned defect, the purpose of this utility model is the light fixture diffuser plate providing a kind of two-sided luminous intensity distribution, under the prerequisite not affecting optical system efficiency, when solution light fixture angle is larger, hot spot is uneven, the problem of diffuser plate image microstructures, make hot spot more even, meet the requirement of people to illuminating effect to greatest extent.
The explanation of composition graphs diagram 1 ~ Fig. 5, the utility model provides a kind of light fixture diffuser plate and light fixture thereof of two-sided luminous intensity distribution, and front 31 and the reverse side 32 of diffuser plate 30 are respectively arranged with micro-structural, as shown in Figure 1.Micro-structural is the structural units of the given shape being arranged on diffuser surface, play the effect of micro lens, the yardstick of micro-structural comprises the yardstick being not limited to naked eyes and seeing, the array be made up of micro-structural is at the opticpath of diffuser plate 30 surface modification diffuser plate 30, and coordinating two-sided shape to arrange mutually corresponding micro-structural can at utmost ensure that emergent light does not produce shade.
Optical module 20, lamp source 10 are set immediately below diffuser plate 30, the front 31 of diffuser plate 30 and the described micro-structural of reverse side 32 are set to the array of curved surface, and the center one_to_one corresponding of the described micro-structural of the center of the described micro-structural in the front 31 of diffuser plate 30 and the reverse side 32 of diffuser plate 30.
The described micro-structural in the front 31 of diffuser plate 30 is set to adjacent hexagon pearl face 311, several each limits, the described micro-structural of the reverse side 32 of described diffuser plate 30 is set to several circular grooves 321, and the center one_to_one corresponding in the center of described circular groove 321 and described hexagon pearl face 311.
Optical module 20 is secondary optical lens, and during concrete enforcement, optical module 20 is collimation lens or nearly collimation lens.The lamp source 10 that diffuser plate 30 is equipped with is LED lamp bead.Diffuser plate 30 adopts optical grade material to make, herein preferably, diffuser plate 30 is optical grade material diffuser plates, and when being made into diffuser plate, material all reaches optical grade level, and the kind of optical grade material comprises Merlon, acrylic, polystyrene, polypropylene etc.
As shown in Figure 2, collimation lens is by being placed on above LED lamp source, and diffuser plate 30 is by being placed on a distance directly over collimation lens for the light fixture diffuser plate of the two-sided luminous intensity distribution of the utility model and an embodiment of light fixture thereof.LED lamp bead is as lamp source 10, the light sent is through collimation TIR (Total Internal Reflection, inner full-reflection) collection of lens, the light of more than 90% all can collimate or penetrate close to collimation, the hexagon pearl face 311 micro-structural refraction arranged through the front 31 of diffuser plate 30, opens collimated light, then reflects through circular groove 321 micro-structural that the reverse side 32 of diffuser plate 30 is concentric with hexagon pearl face 311, further light is spread, reach the effect of even bright dipping.
Many employing single-side optical microstructural diffusion plates in the market, and optical module 20 mostly adopts collimation or close to the lens collimated, the hot spot effect of such bright dipping can make the image microstructures on diffuser plate 30.It is hexagonal shape that one side hexagon pearl face diffuser plate hot spot obviously can see overall hot spot, and edge is uneven, adopt double sided optical microstructural diffusion plate 30, as shown in Fig. 3 ~ Fig. 5, the imaging of micro-structural can be prevented, and hot spot can be allowed more even, hot spot entirety is very evenly and without imaging phenomenon.
The light fixture diffuser plate overall structure of the two-sided luminous intensity distribution of the utility model is not limited to given shape, and can design as required, below diffuser plate 30, optical lens number is not limited to one; Optical lens is not limited to collimation lens, and diffuser plate front micro-structural is not limited to hexagon pearl face, and reverse side micro-structural is not limited to circular groove structure; The micro-structural curved design of the diffuser plate of the design is not limited to special angle, can angular adjustment curved surface as required; The final hot spot effect of the design is not limited to circular light spot.
The utility model also provides a kind of light fixture based on above-mentioned light fixture diffuser plate, does not repeat them here.
In sum, the utility model, by adopting two-sided luminous intensity distribution diffuser plate, not only can make emergent light more evenly soft, avoid dazzle, but also can solve diffuser plate image microstructures problem.The needs of illumination are well positioned to meet, for people provide a comfortable visual environment in a lot of occasion.
Certainly; the utility model also can have other various embodiments; when not deviating from the utility model spirit and essence thereof; those of ordinary skill in the art are when making various corresponding change and distortion according to the utility model, but these change accordingly and are out of shape the protection domain that all should belong to the claim appended by the utility model.
