Abstract
The utility model discloses a kind of LED diffuser, comprise hood-like housing, the outer surface of described hood-like housing is provided with the multiple scattering particles that distribute along outer surface; Described hood-like housing is convex lens.By the way, the utility model can increase LED light scattering angle, and reinforcing reflex efficiency reduces costs when increasing light intensity.
Description
Technical field
The utility model relates to diffuser field, particularly relates to a kind of LED diffuser of the light for LED lamp.
Background technology
LED lamp, due to energy-conservation, the advantage such as the life-span is long, applicability good, environmental protection, is widely used in daily life.LED light source belongs to spot light, because point light source light-emitting point light intensity is excessively strong, human eye is stimulated strong, makes human eye in the time seeing LED illuminator, have dazzling sensation; And the angle maximum of opening the light of LED lamp can only reach 150-165 ° in prior art, reach the luminous LED of wide-angle more etc. if want, can only in LED-backlit module, use more LED lamp, manufacturing the loaded down with trivial details cost that makes increases.
Utility model content
For above-mentioned deficiency of the prior art, the utility model provides a kind of LED diffuser, can increase LED light scattering angle, and reinforcing reflex efficiency reduces costs when increasing light intensity.
For achieving the above object, the technical solution adopted in the utility model is: a kind of LED diffuser, comprise hood-like housing, and the outer surface of described hood-like housing is provided with the multiple scattering particles that distribute along outer surface; Described hood-like housing is convex lens.Multiple scattering particles described in the utility model are convex and are distributed in the outer surface of described hood-like housing, to play the effect of further reflection LED lamp light.
Preferably, described multiple scattering particles are uniformly distributed along the outer surface of hood-like housing.For the light that LED lamp is sent obtains dispersed, multiple scattering particles described in the utility model are evenly distributed at the outer surface of hood-like housing, like this, when LED diffuser described in the utility model is covered on LED lamp, can make the light of LED lamp farthest be disperseed, promote light quality, increase the radiation scope of light.
Preferably, the shape of described multiple scattering particles and size are all consistent.The shape size of the multiple scattering particles described in the utility model is consistent, not only facilitates processing, and can ensure that LED diffuser is even to each angle Monodispersed of light.
Preferably, described multiple scattering particles are multiple convex lens.The protruding multiple scattering particles essence that distribute on hood-like housing described in the utility model are multiple convex lens, like this, light is carried out after first reflection refraction through these larger convex lens of hood-like housing, carry out reflected refraction for the second time through these less convex lens of multiple scattering particles again, thereby realize at utmost dispersing light, make the angle of the light that a LED lamp sends can only reach 150-165 ° from maximum, bring up to and can reach 170 °, even more wide-angle.
Preferably, described each scattering particles and adjacent scattering particles edge are tangent.
Preferably, the bottom of described hood-like housing is provided with fixture block.
Preferably, the bottom even of described hood-like housing is distributed with three fixture blocks.In the utility model for convenience of described hood-like case cover on LED lamp, the bottom of hood-like housing is provided with fixture block, realizes and the assembling of the base plate at LED lamp or LED lamp place handled easily by fixture block.
LED diffuser described in the utility model is different from prior art, its essence is and utilize two-layer convex lens to realize the multiple reflections refraction of light, realize optimization scattering, reach 170 ° of LED scattering angle of release >, the maximum utilization that promotes backlight module taste and realize light with this, saves the energy.
The beneficial effects of the utility model are: the utility model LED diffuser, can increase LED light scattering angle, and reinforcing reflex efficiency, reduces costs when increasing light intensity.

In accompanying drawing, the mark of each parts is as follows: the hood-like housing of 1-, 2-scattering particles, 3-fixture block.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
Refer to Fig. 1, Fig. 2 and Fig. 3, the utility model embodiment mono-: a kind of LED diffuser, comprise hood-like housing 1, the outer surface of hood-like housing 1 is provided with the multiple scattering particles 2 that distribute along outer surface; Hood-like housing 1 is convex lens.When use, LED diffuser described in the utility model is covered on LED lamp.
In the present embodiment, multiple scattering particles 2 are uniformly distributed along the outer surface of hood-like housing 1.
In the present embodiment, the shape of multiple scattering particles 2 and size are all consistent.
In the present embodiment, multiple scattering particles 2 are multiple convex lens.Like this, the LED diffuser of the present embodiment by light after hood-like housing 1 these larger convex lens reflect for the first time, reflect for the second time through multiple scattering particles 2 these less convex lens again, thereby realize at utmost dispersing light, please refer to Fig. 3, thereby make the angle [alpha] of the light that a LED lamp sends can only reach 150-165 ° from prior art maximum, can reach 170 ° and bring up to, even more wide-angle.
The difference of embodiment bis-, the present embodiment and embodiment mono-is, the each scattering particles 2 in the present embodiment are tangent with the edge of adjacent scattering particles 2, to realize more intensive reflection and the refraction of the light that LED lamp is sent, improves the service efficiency of light.
The difference of embodiment tri-, the present embodiment and embodiment mono-is, the bottom even of the hood-like housing 1 in the present embodiment is distributed with three fixture blocks 3.Realize and the assembling of the base plate at LED lamp or LED lamp place handled easily by fixture block 3.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
