Abstract
A kind of stepped ramp type scale and shell lens, lens are located above light source board, lens, which include, to be injected bottom surface, mirrored sides, projects top surface, mirrored sides form horn-like side, mirrored sides form stair-stepping scale and shell face, project top surface and be recessed inner concave arc surface to middle part, the center projections of inner concave arc surface form the convex globoidal of a convex surface mirror-type, and convex globoidal uses cambered surface compound eye micro-structural.In mirrored sides, one step of increase among upper and lower two layers of scale and shell.The utility model is come enlarging lighting area stepped ramp type scale and shell lens by the way of step adds scale and shell, and it makes lens visual effect more preferably, while mitigates lens weight, and hot spot is uniform.
Description
Technical field
Light fixture is the utility model is related to, more specifically to a kind of stepped ramp type scale and shell lens increase by one.
Background technology
By feat of many advantages, overall application rises LED light source in lighting field, the wherein secondary light-distribution of optical lens
To key effect.Traditional LED shot-lights secondary light-distribution lens use individual layer scale and shell cup, lens weight small there is lighting area
The shortcomings of weight.
Utility model content
The purpose of this utility model be to provide it is a kind of can enlarging lighting area mode, by the way of step plus scale and shell
Carry out enlarging lighting area stepped ramp type scale and shell lens, it makes lens visual effect more preferably, while mitigates lens weight, and hot spot is uniform.
In order to reach above-mentioned purpose, solution of the present utility model is：
A kind of stepped ramp type scale and shell lens, lens are located above light source board, and lens, which include, to be injected bottom surface, mirrored sides, penetrates
Go out top surface, mirrored sides form horn-like side, and mirrored sides form stair-stepping scale and shell face, project top surface to middle part indent
Inner concave arc surface is formed, the center projections of inner concave arc surface form the convex globoidal of a convex surface mirror-type, and convex globoidal uses the micro- knot of cambered surface compound eye
Structure.
Further, in mirrored sides, one step of increase among upper and lower two layers of scale and shell.
Further, incident bottom surface is located on light source board for the groove for setting a side wall to be column in the bottom center of lens
Side.
After said structure, the utility model, come enlarging lighting area, regards lens by the way of step adds scale and shell
Feel better；Calculus scale and shell face can make hot spot uniform, anti-dazzle；The middle part for projecting top surface uses cambered surface compound eye micro-structural,
Make hot spot uniform, anti-dazzle, and the camber exiting surface of indent, lens weight can be mitigated, also make lens-shape attractive in appearance, cost drop
It is low, with more the market competitiveness.
Brief description of the drawings
Fig. 1 is front schematic view of the present utility model；
Fig. 2 is schematic rear view of the present utility model；
Fig. 3 is diagrammatic cross-section of the present utility model；
Fig. 4 is that light passes through path schematic diagram of the present utility model.
Embodiment
In order to which the technical solution of the utility model is explained further, the utility model is entered below by specific embodiment
Row elaborates.
With reference to shown in Fig. 1 to Fig. 3, a kind of stepped ramp type scale and shell lens of the present utility model, lens are located above light source board, thoroughly
Mirror, which includes, to be injected bottom surface 1, mirrored sides 2, projects top surface 3.
Wherein, incident bottom surface 1 is located at light source board for the groove 11 for setting a side wall to be column in the bottom center of lens
Above plate, an at least LED light source can be housed in groove, light source can reflect light extraction through incident bottom surface 1.Mirrored sides 2 form loudspeaker
The side of shape, and mirrored sides 2 are in scale and shell face, in the utility model, mirrored sides form stair-stepping scale and shell face, upper and lower two
One step 22 of increase, the big I of step 22 make putting for scale and shell face forming layer scalariform according to actual adjustment among layer scale and shell 21
Distribution is penetrated, so as to enlarging lighting area, while scale and shell uses optics calculus technology, hot spot can be made uniform, anti-dazzle.Project
Top surface is located at lens top surface, projects top surface 3 and is recessed inner concave arc surface 31 to middle part, is formed in the center projections of inner concave arc surface 31
The convex globoidal 32 of one convex surface mirror-type, convex globoidal 32 use cambered surface compound eye micro-structural, hot spot can be made uniform, anti-dazzle.And convex globoidal
32 peripheral exiting surface uses inner concave arc surface 31, can mitigate lens weight.
With reference to Fig. 4, pass through path schematic diagram of the present utility model for light, incident script high angle scattered light passes through step
Type scale and shell face is with after inner concave arc surface, forming the light beam being emitted forward.The utility model increases by the way of step adds scale and shell
Lighting area, make lens visual effect more preferably；Calculus scale and shell face can make hot spot uniform, anti-dazzle；Project and adopted in the middle part of top surface
With cambered surface compound eye micro-structural, make hot spot uniform, anti-dazzle, and the camber exiting surface of indent, lens weight can be mitigated, also make lens
Good appearance, cost reduces, with more the market competitiveness.
Above-described embodiment and schema and non-limiting product form of the present utility model and style, any art
The appropriate change or modification that those of ordinary skill is done to it, all should be regarded as not departing from patent category of the present utility model.
