The advantageous effect of the application:
For the lens of the utility model when assembling LED, staff can select the number of LED as needed, and will be each
LED series connection is placed in guide-lighting slot, realizes that the LED numbers that lens accommodate are adjustable, luminous power is variable, and LED is placed in guide-lighting slot
Afterwards, staff need to only one-time fix lens on wall, easy for installation, and cost is relatively low;By by the position of light-emitting surface
In the position on the first light guiding surface center line toward sunken inside into the 3rd light guiding surface so that be incident upon the light on the 3rd light guiding surface by
Three leaded lights face away from reflecting on the face direction of LED, realize irradiant diverging, and the injection light of lens is avoided largely to gather
Collection on the face direction of LED, ensure lens illumination when without apparent hot spot;It is guide-lighting by removing first at the top of transparent cover
Position outside face sets frosting to carry out diffusing reflection to the light being incident upon thereon, so as to avoid light from transparent cover as far as possible
Top leaks out, and improves the amount of light of transparent cover.
Description of the drawings
The application is described further using attached drawing, but the embodiment in attached drawing does not form any limit to the application
System, for those of ordinary skill in the art, without creative efforts, can also obtain according to the following drawings
Other attached drawings.
Fig. 1 is the partial cutaway view of the LED lens of the application.
Fig. 2 is the structure diagram of the LED lens of the application.
Specific embodiment
The application is further described with the following Examples.
Including plastic transparent cover body, receiving is recessed inwardly at the top of transparent cover for LED lens as depicted in figs. 1 and 2
The guide-lighting slot 1 of LED, the side wall of the leaded light slot 1 are equipped with the first light guiding surface 11 for being gradually collapsed into U-shaped cambered surface from top to bottom, light
Transparent cover is injected from the first light guiding surface 11;The bottom of transparent cover is equipped with the light-emitting surface 12 projected for light, the light-emitting surface 12
Side be outwards to ride out into the second light guiding surface 121 of cambered surface, the position being located on 11 center line of the first light guiding surface of light-emitting surface 12
Past sunken inside is put into the 3rd light guiding surface 122.For lens when assembling LED, staff selects the number of LED as needed, and will
Each LED series connection is placed in guide-lighting slot 1.When lens are mounted, first corresponding hanger is fixed on the wall, then consolidates lens
Determine onto hanger.
Lens are by use, the light that LED is sent is injected from the first light guiding surface 11 in transparent cover, due to the first light guiding surface
11 be U-shaped cambered surface, and light can be refracted to both sides in incidence, and is projected to light-emitting surface 12.Light-emitting surface 12 will be incident upon it again
On light further to two side-refractions so that the illumination zones of lens becomes wide.Largely gather in order to avoid the injection light of lens
Collection is on the face direction of LED, without apparent hot spot when ensureing lens illumination, by being located in the first light guiding surface 11 for light-emitting surface 12
Position on heart line is incident upon the light on the 3rd light guiding surface 122 by the 3rd light guiding surface 122 toward sunken inside into the 3rd light guiding surface 122
It is reflected on towards the face direction away from LED, realizes irradiant diverging.
Frosting 13 is additionally provided in position of the top of transparent cover in addition to the first light guiding surface 11, transparent cover is reflecting
During light, there is some light meeting directive frosting 13, some light diffusing reflection is returned back out smooth surface by frosting 13 at this time
12, so as to as far as possible light be avoided to be leaked out at the top of transparent cover, improve the amount of light of transparent cover.
Preferably, transparent cover for annular shape, guide-lighting slot 1 be looped around it is on the annulus and end to end, under equal volume,
The circular open ended LED numbers of transparent cover are most.
Preferably, transparent cover is additionally provided with the crossed beam trunking 2 that guide-lighting slot 1 is through to from the madial wall of transparent cover, on LED
Electric wire is drawn by crossed beam trunking 2.
Preferably, transparent cover side wall is equipped with shackle member 3, and transparent cover is connected and fixed by shackle member 3 with hanger,
Installation is more convenient.Wherein, there are three shackle members 3, three shackle members 3 are evenly distributed on the madial wall of transparent cover, pass through three
The synchronous clamping of point so that clamping is more firm.Further, mounting hole 31 is set also in shackle member 3, after clamping, work
Screw is screwed on mounting hole 31 by personnel, further fixes transparent cover.
Preferably, transparent cover lateral wall is equipped with three handles 4, and staff revolves transparent cover after holding handle 4
Turn, easily transparent cover is connected on hanger.
Preferably, the top of transparent cover, which is erect, barb 5, and after transparent cover is connected on hanger, barb 5 hooks extension
Frame, transparent cover would not be fallen down.
Preferably, the height of the first light guiding surface 11 is set to 3.2mm, is correspondingly set to the height of the second light guiding surface 121
4.7mm.By the height ratio between fixed first light guiding surface, 11 and second light guiding surface 121, ensureing the item of intensity of illumination
So that illumination range is wide under part.
Preferably, it is found by the applicant that existing lens, between the inner wall and LED light source of the cavity for accommodating LED there are
Air, and when light enters the body of lens from air, since the two is different to the refractive index of light, light can be in lens body
Reflection loss occurs for interface, and accordingly, applicant fills full substratum transparent between the inner wall and LED of the guide-lighting slot 1 of this lens,
Since substratum transparent and transparent cover are all colloidal materials, the refractive index of the two is suitable, and light enters lens by substratum transparent
Body when reflection loss it is less so that more light are able to project by lens, so as to improve the light transmittance of lens.Its
In, the preferred layer of silica gel of substratum transparent, is high active material, and refractive index is closer to plastic lens, and lens are equipped with layer of silica gel
When light transmittance up to 98%.
Finally it should be noted that above example is only to illustrate the technical solution of the application rather than the application is protected
The limitation of scope is protected, although being explained in detail with reference to preferred embodiment to the application, those of ordinary skill in the art should
Work as understanding, the technical solution of the application can be modified or replaced equivalently, without departing from the reality of technical scheme
Matter and scope.
