Abstract
The utility model discloses a kind of rod lens, lens body is strip；Lens body is equipped with LED light slot；Lens body is equipped with limited step；Lens body is equipped with clamping notch；Wherein, lens body shape with wide top and narrow bottom is in back taper, and LED light slot is set to lens body lower part, and the exit facet of lens body is to the inclined inclined-plane in side.The lens body of the utility model is equipped with the exit facet of definite value angle, sufficiently raising light source utilization rate, can be far by light projection without installing angle adjustment device additional, saves cost.
Description
Technical field
The utility model belongs to field of illumination lamp technology, specifically, being related to a kind of rod lens.
Background technique
Wall lamp is primarily used to do building decoration illumination and is used, and also has the profile for sketching the contours heavy construction；Wall lamp
It is mostly strip, light projector distance is adjusted according to the crevice projection angle of light, and angle is smaller, and projection distance is remoter；Some wall lamps
Light projector angle is adjusted using angle adjustment device, although light projector angle is easy to adjust, higher cost.
Utility model content
In view of this, being solved existing the technical problem to be solved by the utility model is to provide a kind of rod lens
The problem of wall lamp adjusts light projector angle using angle adjustment device in technology, higher cost.
In order to solve the above-mentioned technical problem, the utility model discloses a kind of rod lens, lens body is strip；Thoroughly
Mirror main body is equipped with LED light slot；Lens body is equipped with limited step；Lens body is equipped with clamping notch；Wherein, wide on lens body
Under narrow shape be in back taper, LED light slot is set to lens body lower part, and the exit facet of lens body is to the inclined inclined-plane in side.
Further, wherein the face of above-mentioned LED light slot is the plane of incidence.
Further, wherein above-mentioned exit facet and the not parallel out of plumb of the plane of incidence.
Further, wherein above-mentioned clamping notch is located at lens body both ends.
Further, wherein above-mentioned exit facet and lens body upper surface are at 15 ° of angles.
Compared with prior art, the application can be obtained including following technical effect:
The utility model lens body shape with wide top and narrow bottom is in back taper, and LED light slot is set to lens body lower part, LED light slot
Three sides be the plane of incidence, exit facet and the not parallel out of plumb of the plane of incidence, LED light source is injected from the plane of incidence to be rolled over by outer
It is mapped on exit facet, improves the utilization rate of light source；The exit facet of lens body is to the inclined inclined-plane in side, and bevel angle is
Fixed value, lens body can save cost without installing angle adjustment device additional with definite value angle projection light.
Certainly, any product for implementing the application must be not necessarily required to reach all the above technical effect simultaneously.
Detailed description of the invention
The drawings described herein are used to provide a further understanding of the present application, constitutes part of this application, this Shen
Illustrative embodiments and their description please are not constituted an undue limitation on the present application for explaining the application.In the accompanying drawings:
Fig. 1 is the side view of the rod lens of the utility model embodiment；

Attached drawing mark
LED light slot 1, limited step 2 are clamped notch 3, exit facet 4, the plane of incidence 5, angle a.
Specific embodiment
Presently filed embodiment is described in detail below in conjunction with accompanying drawings and embodiments, how the application is applied whereby
Technological means solves technical problem and reaches the realization process of technical effect to fully understand and implement.
Fig. 1, Fig. 2 are please referred to, Fig. 1 is the side view of the rod lens of the utility model embodiment；Fig. 2 is the utility model
The front view of the rod lens of embodiment.A kind of rod lens, lens body are strip；Lens body is equipped with LED light slot 1；
Lens body is equipped with limited step 2；Lens body is equipped with clamping notch 3；Wherein, lens body shape with wide top and narrow bottom is in back taper,
LED light slot 1 is set to lens body lower part, and the exit facet 4 of lens body is to the inclined inclined-plane in side.
Three sides of LED light slot 1 are the plane of incidence 5, exit facet 4 and the not parallel out of plumb of the plane of incidence 5, and light source is injected three and entered
It penetrates in face, is refracted to exit facet by lens outer wall, take full advantage of remaining light and improve intensity of illumination；Clamping notch 3 is located at lens
Main body both ends；At 15 ° of angle a, which debugged by calculating for exit facet 4 and lens body upper surface, is imitated for light projection
The best angle value of fruit.
The utility model lens body shape with wide top and narrow bottom is in back taper, and LED light slot is set to lens body lower part, LED light slot
Three sides be the plane of incidence, exit facet and the not parallel out of plumb of the plane of incidence, LED light source is injected from the plane of incidence to be rolled over by outer
It is mapped on exit facet, improves the utilization rate of light source；The exit facet of lens body is to the inclined inclined-plane in side, and bevel angle is
Fixed value, lens body can save cost without installing angle adjustment device additional with definite value angle projection light.
Several preferred embodiments of the present invention have shown and described in above description, but as previously described, it should be understood that this
Utility model is not limited to forms disclosed herein, and should not be regarded as an exclusion of other examples, and can be used for various
Other combinations, modification and environment, and above-mentioned introduction or related fields can be passed through within the scope of the inventive concept described herein
Technology or knowledge be modified.And changes and modifications made by those skilled in the art do not depart from the spirit and model of the utility model
It encloses, then it all should be in the protection scope of the appended claims for the utility model.
