Description

Light guide rod light-emitting device

Technical Field

The utility model relates to the technical field of lighting technology, especially a leaded light stick illuminator.

Background

The light guide rod conducts light beams by utilizing the reflection principle of light, and changes a point light source into a linear light source. The light intensity of leaded light stick in light source one end is higher, and the luminous intensity of keeping away from light source one end is lower relatively, for making the light of leaded light stick even more, soft, the utility model provides a leaded light stick illuminator.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to above-mentioned prior art not enough, provide a leaded light stick illuminator.

In order to solve the technical problem, the utility model discloses the technical scheme who takes is: a light-guiding rod light-emitting device comprises a light-guiding rod, a lens, a controller and a shell; the light guide rod, the lens and the controller are all arranged in the shell, the lens is positioned at the edge of the shell and is exposed out of one side surface, the lens is connected with the shell in a concave-convex structure, a groove is arranged on a convex structure of the lens, and the light guide rod is arranged in the groove of the lens; the bottommost end of the groove is not lower than the highest point of the exposed side surface of the lens, so that the light guide bar cannot be directly seen outside the shell; the two ends of the light guide rod are connected with the controller, and the light source arranged in the controller irradiates the light guide rod to enable the light guide rod to shine.

In the technical scheme, a light source arranged in a controller has multiple lamp colors including red, blue and green.

In the technical scheme, the lens is provided with a connecting hole, and the connecting hole is formed in the inner side of each edge of the lens and used for being fixed with the shell.

In the technical scheme, the lenses are positioned on 3 outer edges of the shell and are in a U-shaped structure.

The utility model has the advantages that: the groove for placing the light guide bar is arranged in the lens, and the light guide bar cannot be directly seen on the exposed side edge of the lens, so that light reflected on the light guide bar cannot directly irradiate the exposed side edge of the lens, and the light is more uniform and softer.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1-3, a light guide bar lighting device includes a light guide bar 1, a lens 2, a controller 3, and a housing 4. The light guide rod 1 conducts light beams by using the principle of light reflection, and the light guide rod 1 is arranged outside the shell 4 together with the lens 2 and is clamped by the shell 4 up and down. The upper and lower surfaces of the lens 2 are provided with convex structures which are matched with the inner recesses on the shell 4 to form the fixed connection of the concave-convex structures. A groove 21 is arranged in the convex structure on the upper surface of the lens 2, and the groove 21 is used for placing the light guide rod 1. As shown in fig. 2, when the lens 2 is held by the housing 4, only the left side 23 is exposed, and the light transmitted in the lens 2 can be seen only from the side 23. In order to make the light guided by the light guiding rod 1 reflected by the lens 2 to present a more uniform light, the lowest position of the groove 21 on the lens 2 cannot be lower than the highest point of the side surface 23, i.e. the light guiding rod 1 cannot be directly seen in the lens 2. The light guide rod 1 is placed along the track of the groove 21 in the lens 2, and both ends of the light guide rod 1 are connected into the controller 3. Controller 3 is located the inside of shell 4, is equipped with the light source in the controller 3, and controller 3 sends light according to the instruction of machine, and light is through the conduction of leaded light stick 1 for whole leaded light stick 1 all shines. The light of the light guide rod 1 is transmitted by the lens 2, so that the side surface 23 of the lens 2 on the shell 4 presents a lamp color.

Wherein the light sources within the controller 3 may have different colors including, but not limited to, substantially red, green and blue.

Wherein, the lens 2 is provided with a connecting hole 22, and the connecting hole 22 is arranged at the inner side of each edge of the lens 2 and is used for fixing with a shell 24.

Wherein, the lens 2 is arranged on three sides of the shell, and the whole shape of the lens 2 is U-shaped.

The above embodiments are merely illustrative and not restrictive, and all equivalent changes and modifications made by the methods described in the claims are intended to be included within the scope of the present invention.
