Abstract
The utility model discloses a kind of light fixture spreadlight lens, comprise lens body, lens body is bar shaped, the bottom surface of lens body is plane, the end face of lens body is the cambered surface of evagination, cambered surface is comprised of the first cambered surface being smoothly connected and the second cambered surface, and the radius of curvature of the first cambered surface is less than the radius of curvature of the second cambered surface.The utility model spreadlight lens can be realized the unidirectional polarisation of light, has anti-dazzle effect, is conducive to improve the illumination of light fixture illumination simultaneously, and in addition, this spreadlight lens also alternative lampshade plays a protective role to luminescent device.The utility model spreadlight lens can be applicable to multiple light fixture, coordinates and installs and uses with various bar shaped lamp sockets, applied widely.
Description
Technical field
The utility model relates to a kind of lighting lamp accessory, specifically a kind of light fixture spreadlight lens.
Background technology
In daily life, light fixture is seen everywhere, and as the refrigerator of the keeping-freshness storage for article such as food, beverages, for convenience of the bandwagon effect of article in refrigerator, conventionally needs to install lighting in refrigerator.Light fixture generally comprises lamp socket, luminescent device (as LED etc.), lampshade, the light that sends from luminescent device directly or irradiate through lampshade, human eye looks more dazzling, the dazzle producing does not feel like oneself people, and for reaching good illuminating effect, common way is the quantity that increases light source, but this can not tackle the problem at its root, and has increased on the contrary cost.
Summary of the invention
Technical problem to be solved in the utility model is: for the deficiencies in the prior art, provide a kind of light fixture spreadlight lens, can realize the unidirectional polarisation of light, have anti-dazzle effect.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of light fixture spreadlight lens, comprise lens body, described lens body is bar shaped, the bottom surface of described lens body is plane, the end face of described lens body is the cambered surface of evagination, described cambered surface is comprised of the first cambered surface being smoothly connected and the second cambered surface, and the radius of curvature of the first described cambered surface is less than the radius of curvature of the second described cambered surface.
Preferably, the first described cambered surface and the frontal projected area of the second described cambered surface on the bottom surface of described lens body equate substantially, can bonding to the uniformity of the light illumination in field of illumination after polarisation.
Preferably, the both sides of described lens body are respectively arranged with inlay card portion.Arrange after inlay card portion, the draw-in groove match with inlay card portion be set on lamp socket, by by inlay card portion inlay card in draw-in groove, can complete easily the installation of spreadlight lens.
Compared with prior art, the utility model has the advantage of: the disclosed light fixture spreadlight lens of the utility model, simple in structure, easy for installation, while installing and using, the utility model spreadlight lens be arranged in lamp socket and make spreadlight lens be positioned at the top of luminescent device.Because the bottom surface of lens body is the cambered surface that plane, end face are evagination; this cambered surface is comprised of the first cambered surface being smoothly connected and the second cambered surface; the radius of curvature of the first cambered surface is less than the radius of curvature of the second cambered surface; thereby this spreadlight lens can be realized the unidirectional polarisation of light; there is anti-dazzle effect; be conducive to improve the illumination of light fixture illumination, in addition, this spreadlight lens also alternative lampshade plays a protective role to luminescent device simultaneously.The utility model spreadlight lens can be applicable to multiple light fixture, coordinates and installs and uses with various bar shaped lamp sockets, applied widely.
Accompanying drawing explanation
Fig. 1 is the schematic appearance of embodiment spreadlight lens;
Fig. 2 is the cut-away illustration of embodiment spreadlight lens;
Fig. 3 is the illumination schematic diagram of embodiment spreadlight lens.
The specific embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
As shown in Figure 1-2, a kind of light fixture spreadlight lens, the lens body 1 that comprises bar shaped, the bottom surface of lens body 1 is plane, the end face of lens body 1 is the cambered surface of evagination, this cambered surface is comprised of the first cambered surface 11 being smoothly connected and the second cambered surface 12, the radius of curvature of the first cambered surface 11 is less than the radius of curvature of the second cambered surface 12, the first cambered surface 11 and the frontal projected area of the second cambered surface 12 on the bottom surface of lens body 1 equate substantially, the both sides of lens body 1 are respectively arranged with inlay card portion 13, arrange after inlay card portion 13, the draw-in groove (not shown) matching with inlay card portion 13 is set in lamp socket (not shown), by by inlay card portion 13 inlay cards in draw-in groove, can complete easily the installation of spreadlight lens.
Said lens body can be made by PMMA material.
This spreadlight lens can be realized the unidirectional polarisation of light, there is anti-dazzle effect, be conducive to improve the illumination of light fixture illumination simultaneously, for example, for the light fixture that has assembled the utility model spreadlight lens, if setting height(from bottom) is 270mm, when the bottom surface of spreadlight lens and the angle of lamp installation face are 37.5 °, better to the lighting effect of below 400mm width regions, the illumination schematic diagram of its light fixture as shown in Figure 3, the illumination at A place, this region can reach 60%, B place can reach 100%.
In actual applications, the utility model spreadlight lens can be applicable to multiple light fixture, coordinates and installs and uses with various bar shaped lamp sockets, applied widely.
Claims (3)
1. a light fixture spreadlight lens, comprise lens body, it is characterized in that described lens body is bar shaped, the bottom surface of described lens body is plane, the end face of described lens body is the cambered surface of evagination, described cambered surface is comprised of the first cambered surface being smoothly connected and the second cambered surface, and the radius of curvature of the first described cambered surface is less than the radius of curvature of the second described cambered surface.
2. a kind of light fixture spreadlight lens according to claim 1, is characterized in that the first described cambered surface and described the second cambered surface frontal projected area on the bottom surface of described lens body equates substantially.
