Abstract
The utility model discloses a kind of rectilinear lenses, including：Mounting base, lens, incidence surface, light-emitting surface, lamp source placing groove, refracted slot, groove, convex block, sealing ring, cover board.The utility model advantageous effect is：By covering in lamp source placing groove in lamp source, because lamp source placing groove is corresponding with lens, light source penetrates lens by the incidence surface of lens, then is reflected by light-emitting surface, and refracted slot is equipped with above the light-emitting surface of lens, so can pass through refracted slot optically focused after light source refraction；Meanwhile mounting base upper end is provided with cover board made of PC materials, cover board makes refracted slot be in enclosure space, and external dust enters less than in refracted slot, so that lens are constantly in clean, bright state, stronger light gathering is also always maintained at constant.
Description
Technical field
The utility model is related to lens technologies, and in particular to a kind of rectilinear lens.
Background technology
Lens are the optical elements that the surface made of transparency material is piece, and lens have stronger prefocus
Power, so with its road Lai Zhao, not only road surface is bright, but also clear；Therefore lens are set in existing LED bulb, LED is made to shine
The light source of body transmitting can penetrate lens and generate illumination effect, however current reflection from lens cambered surface is larger, and light gathering is poor, cause
Keep the reflecting effect of LED lamplight not bright enough, could be improved.In addition, the wearability of lens is poor, often wiping is highly vulnerable to breakage
Lens surface structure, does not wipe, and the dust of long-time lens surface attachment can also influence the light gathering of lens.
Utility model content
For the comprehensively solve above problem, in particular for deficiency of the prior art, the utility model provides one
Kind rectilinear lens being capable of the comprehensively solve above problem.
To achieve the above object, the utility model uses following technological means：
A kind of rectilinear lens includes lens, further includes having mounting base, and the lens are set in mounting base, lens packet
Incidence surface and light-emitting surface are included, the bottom of the mounting base is equipped with lamp source placing groove corresponding with incidence surface, the mounting base court
It is equipped with refracted slot corresponding with light-emitting surface to one end of light-emitting surface, several grooves are provided in the mounting base upper end,
The mounting base upper end is provided with cover board, and the cover board lower end is provided with convex block, and the groove is connect with convex block bumps.
Further, the mounting base is integrally formed with lens.
Further, the lens are placed in refraction trench bottom, and the diameter of the refracted slot is more than the straight of lens light-emitting surface
Diameter.
Further, the incidence surface and light-emitting surface are convex-shaped arc surface.
Further, the cover board is made of PC materials.
Further, it is provided with sealing ring on the outside of the cover board.
The utility model advantageous effect is：A kind of rectilinear lens provided by the utility model, by by lamp source placing groove cover
In in lamp source, because lamp source placing groove is corresponding with lens, light source penetrates lens by the incidence surface of lens, then is rolled over by light-emitting surface
Penetrate, refracted slot be equipped with above the light-emitting surfaces of lens, thus after light source refraction can by refracted slot optically focused, meanwhile, the utility model
Mounting base upper end is provided with cover board made of PC materials, and cover board makes refracted slot be in enclosure space, and external dust enters not
Into refracted slot, so that lens are constantly in clean, bright state, stronger light gathering is also always maintained at constant.
Description of the drawings
Fig. 1 is the sectional view of the utility model.
In figure：1- mounting bases, 2- lens, 21- incidence surfaces, 22- light-emitting surfaces, 3- lamp source placing grooves, 4- refracted slots, 5- are recessed
Slot, 6- convex blocks, 7- sealing rings, 8- cover boards.
Specific implementation mode
The utility model is described further below in conjunction with the accompanying drawings, wherein the identical reference numeral of identical parts
It indicates.It should be noted that word "front", "rear" used in the following description, "left", "right", "up" and "down" refer to it is attached
Direction in figure, word "inner" and "outside" refer respectively to the direction towards or away from geometric center of specific component.
As shown in Figure 1, the utility model includes：Lens 2 further include having mounting base 1, and the lens 2 are set to mounting base 1
On, lens 2 include incidence surface 21 and light-emitting surface 22, and the bottom of the mounting base 1 is put equipped with lamp source corresponding with incidence surface 21
Slot 3 is set, the mounting base 1 is equipped with refracted slot 4 corresponding with light-emitting surface 22, the mounting base towards one end of light-emitting surface 22
Several grooves 5 are provided in 1 upper end, 1 upper end of the mounting base is provided with cover board 8, and 8 lower end of the cover board is provided with convex block 6,
The groove 5 is connect with 6 bumps of convex block.
Mounting base 1 is integrally formed with lens 2, by mold one-pass molding, to improve the life of mounting base 1 and lens 2
Efficiency is produced, the production cost of mounting base 1 and lens 2 has been saved.
Lens 2 are placed in 4 bottom of refracted slot, and the diameter of the refracted slot 4 is more than the diameter of 2 light-emitting surface of lens, sets in this way
It postpones, the light source reflected by refracted slot 4 is wider, also more bright.
Incidence surface 21 and light-emitting surface 22 are convex-shaped arc surface, in this way after setting, the light source that is reflected by two convex-shaped arc surfaces
Best results, light source are also more bright.
Cover board 8 is made of PC materials, and cover board 8 made of PC materials has high transparency, high refractive index, impact, ruler
The characteristics of very little stability and easy processing are molded.
The outside of cover board 8 is provided with sealing ring 7, and sealing ring 7 can improve the leakproofness between cover board 8 and mounting base 1, into
One step prevents dust from entering in refracted slot 4.
A kind of rectilinear lens provided by the utility model, by covering in lamp source placing groove 3 in lamp source, because of lamp source placing groove
3 is corresponding with lens 2, and light source penetrates lens 2 by the incidence surface 21 of lens 2, then is reflected by light-emitting surface 22, and lens 2 go out
The top of smooth surface 22 is equipped with refracted slot 4, thus after light source refraction can by 4 optically focused of refracted slot, meanwhile, the utility model mounting base 1
