Abstract

The utility model relates to the technical field of lens, in particular to a light-gathering lens for a high-power LED infrared emission tube which comprises an integrally-molding lens body. The bottom end of the lens body is molded with a truncated-cone-shaped light-gathering body; the bottom end of the light-gathering body is molded with a protruded part used for the placement of an LED. Because the bottom end of the lens body is molded with the truncated-cone-shaped light-gathering body, the light emitted by the LED can be gathered by the light-gathering body with large volume and good light-gathering effect and then transmitted out, thereby improving the light-gathering effect of the high-power LED infrared emission tube and increasing the radiation distance of the LED infrared emission tube.

Description

The collector lens of great power LED infrared transmitting tube
Technical field:
The utility model relates to the lens technologies field, relates in particular to a kind of collector lens of great power LED infrared transmitting tube.
Background technology:
Because LED (Light Emitting Diode, light emitting diode) long service life, energy consumption is low, energy savings is remarkable, LED has been widely used in the daily life as light source, as being installed in the great power LED infrared transmitting tube of security monitoring devices such as video camera, it is low in energy consumption, irradiation distance is far away, long service life.General great power LED infrared transmitting tube in use, the bright dipping that requires LED is the focused beam with definite shape, with the rising angle of control light, and increases the irradiation distance of great power LED infrared transmitting tube.At present, most great power LED infrared transmitting tube all is the PC (Polycarbonate by LED self, Merlon) lid comes focused ray, because the volume of PC lid is little, spotlight effect is poor, causes the irradiation distance of great power LED infrared transmitting tube nearer, and, when the great power LED infrared transmitting tube needs different rising angles, must change different LED, manipulate comparatively trouble.
The utility model content:
The purpose of this utility model is exactly the collector lens that the good great power LED infrared transmitting tube of a kind of spotlight effect is provided at the deficiency of prior art existence.
To achieve these goals, the technical solution adopted in the utility model is:
It comprises integrated lens body, and the bottom of described lens body forms the optically focused cup of truncated cone-shaped, and the bottom of optically focused cup forms the protuberance that is used to place LED.
Wherein, the bottom of described lens body forms reference column.
Wherein, offer groove on the described protuberance.
The utility model beneficial effect is:
The collector lens of the great power LED infrared transmitting tube that the utility model provides comprises integrated lens body, the bottom of described lens body forms the optically focused cup of truncated cone-shaped, the bottom of optically focused cup forms the protuberance that is used to place LED, owing to form the optically focused cup of truncated cone-shaped in the bottom of lens body, the light that makes LED send can be bigger through volume, after the spotlight effect focusing of optically focused cup preferably, launch again, thereby improved the spotlight effect of great power LED infrared transmitting tube, increased the irradiation distance of great power LED infrared transmitting tube.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model other direction.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described, see shown in Fig. 1,2, the utility model comprises integrated lens body 1, the bottom of described lens body 1 forms the optically focused cup 2 of truncated cone-shaped, certainly, the physical dimension of optically focused cup 2 as the concavo-convex situation of radius of curvature, inside, can be set according to different bright dipping requirement and spotlight effect; In the present embodiment, the bottom of described optically focused cup 2 forms the protuberance 3 that is used to place LED; Offer groove 5 on the described protuberance 3, be used to place the electrode of drawing on the LED; The bottom of described lens body 1 forms reference column 4, so that the installation of collector lens location.
The utility model can be installed in the great power LED infrared transmitting tube of security monitoring devices such as video camera, owing to form the optically focused cup 2 of truncated cone-shaped in the bottom of lens body 1, make light that LED sends can be big through volume, after the spotlight effect focusing of optically focused cup 2 preferably, launch again, thereby improved the spotlight effect of great power LED infrared transmitting tube, increased the irradiation distance of great power LED infrared transmitting tube.Further, when the great power LED infrared transmitting tube needs different rising angles, need not to change LED, because optically focused cup 2 decision rising angles, as long as change the collector lens of different optically focused cups 2, the PC lid of collector lens and LED is worked in coordination, just can form satisfactory rising angle, manipulate very convenient.
Certainly, the above only is preferred embodiment of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
