Embodiment 1

[0039] Such as figure 1 As shown, an optical fiber light-emitting structure includes a reflective sheet 1, an optical fiber layer arranged on the reflective sheet 1, a light source connected to the optical fiber layer, a small hole arranged on the upper side of the optical fiber layer, and an optical fiber layer arranged on the optical fiber layer and the reflective sheet. The bottom layer of transparent glue layer 6 between 1; the optical fiber layer is made up of several optical fibers, the front section of the optical fiber is the light-emitting surface, the rear section is the guiding line, the light-emitting surface of the optical fiber is fixed on the reflective sheet 1, and the leading line ends are connected with the The light source is connected; the small hole or the scribe line is formed after stripping the coating layer of the optical fiber, and the small hole is set against the reflection sheet 1 .

[0040] The small hole is a circular hole, which is mainly obtain...

Embodiment 2

[0049] The difference between this embodiment and embodiment 1 is that, as Figure 4 As shown, the optical fiber also includes an upper optical fiber 9 or a lower optical fiber 10 or a combination of an upper optical fiber 9 and a lower optical fiber 10; the light source also includes an upper light source 11 connected to the upper optical fiber 9 and a lower optical fiber connected to the lower optical fiber 10 Light source 12; the number of the upper light source 11 and the lower light source 12 is at least one.

[0050] While laying the left and right optical fibers horizontally, whether the upper optical fiber and the lower optical fiber are used alone or at the same time will not affect the normal use of the product. It can be selected according to actual needs to improve the scope of application of the product. The upper light source is connected to the upper optical fiber, and the lower light source is connected to the lower optical fiber, so that the part of the optica...

Embodiment 3

[0056] The only difference between this embodiment and Embodiments 1 and 2 is that figure 2 As shown, the upper side of the optical fiber layer is further provided with a top layer of transparent glue layer 7 and a diffusion sheet 8 in sequence.

[0057] The shape and size of the diffusion sheet need to be consistent with the reflective sheet.

Abstract

The invention discloses an optical fiber light emitting structure. The optical fiber light emitting structure comprises a reflecting plate, an optical fiber layer arranged on the reflecting plate, a light source connected with the optical fiber layer, small holes formed in the upper side of the optical fiber layer, and a bottom transparent glue layer arranged between the optical fiber layer and the reflecting plate; the optical fiber layer is composed of a plurality of optical fibers, the front section of each optical fiber is a light emitting surface, the rear section of each optical fiber isa light guiding line, the light emitting surface of each optical fiber is fixed to the reflecting plate, and the end of each light guiding line is connected with the light source; the small holes ormarks are formed after optical fiber coatings are stripped off and are formed away from the reflecting plate. The invention further discloses a laser dotting processing method of the optical fiber light emitting structure. The optical fiber light emitting structure and the laser dotting processing method have the advantages that the light emitting structure is uniform in light emission, lower in energy consumption, larger in coverage area, lighter and thinner, convenient to use, safe and reliable, and the processing method of the light emitting structure is simpler. The invention further provides a glue dotting device which further improves the processing efficiency.

Description

technical field [0001] The invention belongs to the field of lighting and lighting, and specifically refers to an optical fiber lighting structure and a laser dotting processing method. Background technique [0002] The optical fiber is composed of two layers of glass with different refractive indices. The inner layer is the optical core with a diameter of several microns to tens of microns, and the outer layer has a diameter of 0.1 to 0.2 mm. Generally, the refractive index of the inner core glass is 1% larger than that of the outer glass. The outermost structure of the optical fiber is the coating layer. When the glass optical fiber is pulled out of the preform rod, in order to prevent contamination by dust, a layer of elastic coating is cured with ultraviolet light; it is made of acrylate, silicone rubber, Composed of nylon and PMMA. [0003] The purpose of making optical fibers is to transmit light signals, so companies and researchers in this field have formed inertia...
