Abstract
The utility model relates to the technical field of lenses, particularly to a lens module for an LED tunnel lamp, which comprises an integrally formed lens body. The lens body is made of transparent polycarbonate (PC) and is in a shape of a flat and straight block, two or more semi-ellipsoidal light transmitting cups are formed at the bottom of the lens body, an inner recessed part for holding an LED lamp is arranged at the top of each transmitting cup, and the bottom end surface of the inner recessed part is downwardly recessed. The LED lamps can be placed in the inner recessed parts of the light transmitting cups, and the distance between the LED lamps and the lens body is small, so that the light emitted from each LED lamp can be diffused, reflected and scattered, which reduces the impact of diverging light among the LED lamps and ensures the same emergence angle of light emitted by the LED lamps. The LED tunnel lamp lens module fully utilizes the light emitted by each LED lamp and has increased brightness.
Description
Technical field:
The utility model relates to the lens technologies field, relates in particular to a kind of LED Tunnel Lamp lens module.
Background technology:
Generally can be provided with lens on the shell of LED (Light Emitting Diode, light emitting diode) Tunnel Lamp, be used to enlarge the range of exposures of LED lamp.The lens of the existing LED of being used for Tunnel Lamp mainly adopt by what glass was made and are hemispheric concavees lens, promptly the middle part cave inward, the block glass of perk all around, though the light that this lens can send LED lamp diffusion, but, because the distance between LED lamp and the lens surface is bigger, cause the difficult control of rising angle of LED lamp easily, be that the light that the LED lamp sends is comparatively dispersed, the light that makes the LED lamp send can not be utilized fully, reduce the brightness of LED Tunnel Lamp, influenced the safety of tunnel driving.
The utility model content:
The purpose of this utility model is exactly the LED Tunnel Lamp lens module that the brightness of a kind of LED of raising Tunnel Lamp 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, the described lens body of being made by transparent PC is straight bulk, its bottom forms two or more printing opacity cups, the printing opacity cup is the semiellipsoid shape, the top of printing opacity cup offers the inner fovea part that is used to place the LED lamp, and the bottom end face of inner fovea part is to lower recess.
The inner fovea part of described printing opacity cup is coniform.
Described lens body is rectangular, and the printing opacity cup is the bottom that matrix is arranged in lens body.
The printing opacity cup of described lens body bottom be 12.
Offer screw hole on the described lens body.
Offer the groove that is used to place waterproof apron on the described lens body.
Form reinforcement on the described lens body.
The utility model beneficial effect is:
The LED Tunnel Lamp lens module that the utility model provides comprises integrated lens body, the described lens body of being made by transparent PC is straight bulk, its bottom forms two or more printing opacity cups, the printing opacity cup is the semiellipsoid shape, the top of printing opacity cup offers the inner fovea part that is used to place the LED lamp, and the bottom end face of inner fovea part is to lower recess; Because the LED lamp in the LED Tunnel Lamp can be placed in the inner fovea part of printing opacity cup, distance between LED lamp and the lens body is less, the light that makes each LED lamp send can spread respectively with reflective, scatter out again, reduced the divergent rays influence between each LED lamp, the rising angle that has guaranteed the light that a plurality of LED lamps send is identical, thereby has made full use of the light that each LED lamp sends, the brightness that has improved the LED Tunnel Lamp.
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;
Fig. 3 is a upward view of the present utility model;
Fig. 4 is the A-A cutaway view of Fig. 3;
Fig. 5 is the B-B cutaway view of Fig. 3.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described, see shown in Fig. 1～5, the utility model comprises integrated lens body 1, the described lens body of being made by transparent PC 1 is straight bulk, its bottom forms two or more printing opacity cups 2, printing opacity cup 2 is the semiellipsoid shape, the top of printing opacity cup 2 offers the inner fovea part 3 that is used to place the LED lamp, the bottom end face of inner fovea part 3 is to lower recess, more particularly, the inner fovea part 3 of described printing opacity cup 2 is coniform, cone shape inner fovea part 3 jointly constitutes concavees lens with diffusion effect of light with the printing opacity cup that is the semiellipsoid shape 2 that protrudes downwards, when the LED lamp in the LED Tunnel Lamp is placed in the inner fovea part 3 of printing opacity cup 2, distance between LED lamp and the lens body 1 is less, the light that each LED lamp sends can be respectively by the diffusion of the corresponding printing opacity cup of placing 2 and reflective, scatter out again, reduced the divergent rays influence between each LED lamp, the rising angle that has guaranteed the light that a plurality of LED lamps send is identical, thereby made full use of the light that each LED lamp sends, the brightness that has improved the LED Tunnel Lamp; Wherein, rising angle of the present utility model is used for the LED Tunnel Lamp for vertically downward, can avoid dazzling the eyes sense, in order to avoid influence the safety of tunnel driving.
The lens body 1 of present embodiment is rectangular, and printing opacity cup 2 is the bottom that matrix is arranged in lens body 1, make the LED Tunnel Lamp irradiate rectangular light spot, and bright dipping is even; Certainly, the physical dimension of printing opacity cup 2 and inner fovea part 3 as the concavo-convex situation of radius of curvature, curved inner surface, can be set according to different bright dipping requirement and lighting effect, as set long to rising angle be 90 degree, wide to rising angle be 60 degree, to improve the brightness of LED Tunnel Lamp.
The printing opacity cup 2 of present embodiment lens body 1 bottom be 12, promptly 12 printing opacity cups 2 are formed a module, so the utility model can be formed the LED Tunnel Lamp of different LED lamp number, can form the LED Tunnel Lamp of 72 LED lamps, 8 modules as 6 modules and can form the LED Tunnel Lamp that the LED Tunnel Lamp of 96 LED lamps, 10 modules can be formed 120 LED lamps.Therefore, the utility model has characteristics such as in light weight, that volume is little by the lens body 1 that transparent PC makes, and can be convenient to the transportation and the installation of LED Tunnel Lamp.
Offer screw hole 4 on the present embodiment lens body 1, be used to install and fix lens body 1; Also offer the groove 5 that is used to place waterproof apron on the described lens body 1, groove 5 is positioned at all sides at lens body 1 top ringwise, forms reinforcement 6 on the lens body 1, makes the structure of lens body 1 more firm.
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.
