Abstract
The invention relates to an optical lens, in particular to an LED optical lens applied to refrigerators. The LED optical lens includes a lens body and a lens hood matched with the lens body. An accommodating cavity for accommodating LED lights is arranged on the lens body. A rack structure used for refracting LED light is further arranged on the lens body. The rack structure of the LED optical lens can well refracts lights, so the lighting angle is enlarged to the maximum extent, the light use ratio is sufficiently improved, and the lighting evenness is ensured.
Description
Technical field
The present invention relates to a kind of optical lens, be specifically related to a kind of LED light lens be applied in refrigerator.
Background technology
Existing LED illumination lamp is due to good energy-conserving effect, therefore be also widely used in refrigerator, but because LED is that one side is luminous, lighting angle is little, the shortcomings such as central light strength is concentrated, so translucent effect is unsatisfactory, simultaneously current refrigerator light mounting means is most is upper lateral installation, the effective rate of utilization that this mounting means result in illumination is extremely low, at the shadow surface uniform illumination extreme difference of whole refrigerator, when people and refrigerator-freezer are hoped to refrigerator in side, the eyes of people are produced and certain dazzles light present situation.
Summary of the invention
The object of this invention is to provide a kind of lighting angle large, translucent effect more preferably and be arranged on the LED light lens that can increase illumination utilization rate in refrigerator, a kind of LED light lens, it is characterized in that: the light shield comprising lens body and coordinate with lens body, described lens body is provided with the accommodating cavity of accommodating LED, described lens body is also provided with the rack structure for reflection LED lamp light.
Further, the fixed cover coordinating light shield is also comprised.
Further, the inclined-plane that described rack structure is provided with tooth bar by three outsides forms.
Further, the surface of described rack structure is Fresnel Lenses face.
Further, described lens body is provided with fixing hole.
Further, described light shield is provided with the jack coordinating fixing hole.
Beneficial effect of the present invention is: adopt the present invention, well can be reflected by light, thus add lighting angle to greatest extent, add illumination utilization rate fully, also ensure that the uniformity of illumination simultaneously by the rack structure of LED light lens.
Accompanying drawing explanation
Fig. 1 is the structural representation of lens body in the present invention;
Fig. 2 is the structural representation of light shield in the present invention;
Wherein, 1 is lens body, and 11 is accommodating cavity, and 12 is rack structure, and 121 is tooth bar, and 13 is fixing hole, and 2 is light shield, and 21 is jack.
Detailed description of the invention
Below in conjunction with accompanying drawing and the preferred specific embodiment of the present invention, structure of the present invention is further described, first embodiment, a kind of LED light lens, the light shield 2 comprising lens body 1 and coordinate with lens body 1, described lens body 1 is provided with the accommodating cavity 11 of accommodating LED, described lens body 1 is also provided with the rack structure 12 for reflection LED lamp light, these LED light lens further comprises the fixed cover coordinating light shield 2, this fixed cover is identical with light shield 2 shape, therefore its accompanying drawing is not provided in the present embodiment, the inclined-plane that described rack structure 12 is provided with tooth bar 121 by three outsides forms, its surface is Fresnel Lenses face, for the ease of fixing, lens body 1 is provided with fixing hole 13, light shield 2 is provided with the jack 21 coordinating fixing hole 13.In the present embodiment, light shield 2 is the middle shape in half spherical cambered surface, lens body 1 is as represented in accompanying drawing, the mid portion of lens body 1 is the form coordinating light shield 2 hemisphere arc shape, the rack structure 12 that lens body 1 is provided with, rack structure 12 is one-sided setting, be made up of three inclined-planes, inclined-plane is provided with tooth bar 121, the size of tooth bar 121 and density can regulate according to actual conditions, namely according to the dark degree adjustment of the light in range of exposures district, with reach irradiate rectangular aspect ratio requirement and whole shadow surface in the uniformity of light, thus ensure that lighting angle and add illumination utilization rate, concrete, LED light enters lens body 1 by the reflex of light shield 2, light refraction is gone out by rack structure by the light of reflection again.
Second embodiment, is with the first embodiment difference, and rack structure is that bilateral is arranged.In order to better effects if in actual applications, can be arranged on adopting the lamp of these LED light lens just to the rear side centre of refrigerator doors, being convenient to improve illumination utilization rate better.
Claims (6)
