Abstract
The utility model discloses an LED cylindrical lens which comprises a cone-shaped lens cup body and a front-end mirror surface, wherein the tail end of the lens cup body is provided with a cavity accommodating the LED; the front-end mirror surface is provided with a plurality of waved ribs; the light emitting angle of the lens along the length direction of the ribs is among 10-15 degrees; and the light emitting angle of the lens along the width direction of the ribs is among 60-70 degrees. Since the utility model adopts the cylindrical lens with a plurality of strip bodies, compared with a light distribution cup in the prior art, the LED cylindrical lens have the advantages of easily light emitting angle control, high light emitting efficiency, long service life and the like.
Description
[described technical field]
The utility model relates to a kind of optical lens, refers in particular to a kind of LED cylindrical lens.
[background technology]
The rising angle of existing LED is generally all between 30 °～60 °, or astigmatism, or optically focused, and it is single to go out light effect, can't directly apply to specific lighting field, as body of wall illumination, road lighting etc.In the lighting field of reality, in order to satisfy the lighting effect of expection, present predetermined rising angle for the requirement of the rising angle of light source in predetermined direction, so that effectively utilize the light of LED.General optical lens and luminous intensity distribution cup by secondary carries out the light path rectification in the prior art.As the Chinese patent publication number is the patent of invention of CN101255974, this patent documentation discloses a kind of luminous intensity distribution cup that adopts and has changed the luminous intensity distribution cup of LED rising angle with the rectangular light spot of acquisition expection, solved the technical problem of the rising angle of LED, thereby the hot spot that makes it obtain expecting, but there is part light being absorbed by glow cup itself in this technical scheme through the reflector reflex time, and long-time sudden and violent leakage of reflector is exposed to the sun under strong sunlight, add the high temperature of LED and power supply, the reflector efficiency of the luminescent film of plating in the reflector cup is descended, the light extraction efficiency of light fixture is reduced.So people thirst for obtaining a kind ofly can adjusting the high light distribution element of LED rising angle, long service life and light extraction efficiency always.
[utility model content]
In view of the technical problem that exists in the prior art, the purpose of this utility model is to provide a kind of can adjust the high LED cylindrical lens of LED rising angle, long service life and light extraction efficiency.
In order to reach above-mentioned technical purpose, the technical scheme that the utility model adopted is a kind of LED cylindrical lens, comprise taper lens cup and front end minute surface, the tail end of described lens cup is provided with the cavity of a ccontaining LED, described front end minute surface is provided with a plurality of ribs of undulate, described lens along the rising angle of the length direction of rib between 10 °～15 °, described lens along the rising angle of the width of rib between 60 °～70 °.
Because the utility model adopts band to have the cylindrical lens of rib, has plurality of advantages such as rising angle is controlled easily, light extraction efficiency height, long service life with respect to luminous intensity distribution cup of the prior art.
Preferably, the profile of described cavity and LED is complementary.
Preferably, the height of described rib is between 0.1mm～1mm, and the width of described rib is between 0.5mm～2mm.
Preferably, the height of described taper lens cup is between 10mm～15mm, and the rim of a cup diameter of described taper lens cup is between 20mm～25mm, and the tail end diameter of described taper lens cup is between 6mm～8mm.
Preferably, the height of described taper lens is 12mm, and the rim of a cup diameter of described taper lens cup is 22mm, and the tail end diameter of described taper lens cup is 7mm.
[description of drawings]
Figure 1 shows that perspective view of the present utility model;
Figure 2 shows that side structure schematic diagram of the present utility model;
Figure 3 shows that among Fig. 2 structural representation along the A-A section;
Figure 4 shows that analog ligand light effect figure of the present utility model.
[specific embodiment]
In order to introduce the utility model in further detail, further detailed description is done in design of the present utility model below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model discloses a kind of LED cylindrical lens, these lens comprise taper lens cup 1 and front end minute surface 2, and the tail end of described lens cup 2 is provided with the cavity 3 of a ccontaining LED, and described front end minute surface 2 is provided with a plurality of ribs 4 of undulate; As shown in Figure 2, light on the length direction of rib 4 and the angle 3 of lens axis between 5 °～7.5 °, promptly these lens along the rising angle of the length direction of rib 4 between 10 °～15 °; As shown in Figure 3, lens along the rising angle α of the width of rib 4 between 60 °～70 °.
In order further to improve structure of the present utility model, can do further to optimize to the technical solution of the utility model:
Preferably, cavity 3 is complementary with the profile of LED, so that LED better location in cavity 3.
As shown in Figure 3, the height h of rib 4 is between 0.1mm～1mm, and the width d of rib 4 is between 0.5mm～2mm.
As shown in Figure 2, the height F of taper lens cup 1 is between 10mm～15mm, and the rim of a cup diameter L of taper lens cup 1 is between 20mm～25mm, and the tail end diameter K of taper lens cup 1 is between 6mm～8mm.
As further optimization of the present utility model, the height F of taper lens cup 1 is 12mm, and the rim of a cup diameter L of taper lens cup 1 is 22mm, and the tail end diameter K of taper lens cup 1 is 7mm.
Because cylindrical lens of the present utility model is less along the rising angle on rib 4 length directions, generally between 10 °～15 °, and it is relatively large along the rising angle of the width of rib 4, generally between 60 °～70 °, therefore these lens can elongate the LED hot spot, finally are rendered as the hot spot of strip.As shown in Figure 4, shown in Figure 4 is the analog ligand light effect line chart of cylindrical lens of the present utility model, the hot spot that final bright dipping hot spot of the present utility model shown in Figure 4 is a strip, and the hot spot of this strip can be widely used in various body of wall lighting fields.
More than about the design of the parameters of lens, be the preferred version that the inventor draws through repetitious experiment, the lens according to parameters of the present utility model is made are particularly useful for various light fixtures such as LED Projecting Lamp, LED wall lamp, auto bulb.
Because the utility model adopts the cylindrical lens that has a plurality of strip shape bodies that LED is carried out luminous intensity distribution, has plurality of advantages such as rising angle is controlled easily, light extraction efficiency height, long service life with respect to luminous intensity distribution cup of the prior art.
Above only the act illustrates the utility model with convenience, and in not breaking away from creation spirit category of the present utility model, any simple modification that those skilled in the art did of being familiar with this technology still belongs to protection domain of the present utility model with distortion.
