Manufacturing process of optical fiber illuminator module lamp

Abstract

The invention discloses a manufacturing process of a light guide fiber illuminator module lamp. Firstly, a housing, a light source plate and a locking core are assembled into a module; The lamp consists of a housing and a light source board. Mounting holes are opened on the housing, and light sources corresponding to the mounting holes are set on the light source board. The light guide fiber is plugged and fixed through the lock core on the installation hole. The inner end of the light guide fiber is from Light is obtained from the corresponding light source. The lock core includes a lock tube, a lock bead, a compression spring, and a positioning component that has a through hole and is fixed to the housing. A first small outer and inner large end is provided at the end of the through hole close to the mounting hole. Tapered surface, the outer wall of the inner end of the lock tube is a second cone surface matched with the first cone surface, and at least one lock bead is clamped in the second cone surface of the inner end of the lock tube, and the compression spring is cushioned on the lock tube The inner end of the optical fiber is realized, so that the plug and play of the optical fiber is realized, and the reliability and stability of the optical fiber installation are effectively improved.

Description

technical field [0001] The invention belongs to the technical field of lamps, and in particular relates to a manufacturing process of a light guide fiber emitter module lamp. Background technique [0002] At present, with the advancement of technology, LED fiber optic lamps are becoming more and more popular, and their applications in the field of architectural decoration are becoming more and more extensive. Traditional architectural decoration LED fiber optic decorative lamps mainly use wooden boards pasted with mirror panels or sound-absorbing cotton as the shell, and the shell is punched to insert light-guiding fibers, and the rear ends of multiple light-guiding fibers are connected to a light emitter. The description of the patent document CN202650262U is attached figure 2 In , the way of traditional light guide fiber to obtain light source is given. Moreover, the light guide fiber of the traditional architectural decoration LED optical fiber decorative lamp is fixed ...

AI Technical Summary

Problems solved by technology

[0004] 1. The fixing method between the light guide fiber and the housing is simple and rough. In order to ensure that the light guide fiber is firmly fixed, the tight clamping force of the toothpick or the high temperature of the hot melt adhesive will inevitably cause the light guide fiber to deform or even break. The light guide fiber installed in this way cannot be disassembled and cannot be reused; if in order to avoid deformation or breakage of the light guide fiber, use a looser clamping force of a toothpick or a lower temperature of the hot melt adhesive, which will affect the connection between the light guide fiber and the housing. The reliability of the fixed connection between them, especially in the transportation vibration, the fixing of the light guide fiber is very easy to fail; moreover, the fixation of each light guide fiber on the housing requires toothpicks or hot melt glue, which is very troublesome to operate. It requires a lot of labor, which is not conducive to cost control; and hot melt adhesive heating will produce a pungent smell, which is not conducive to environmental protection;

[0005] 2. Multiple light guide fibers correspond to the same light emitter, and each light guide fiber needs to go from the light emitter to the mounting hole of the housing, the length of which is long and the material cost is high; such multiple light guide fibers correspond to the same light emitter, Affected by the caliber of the light emitter and the angle of light emission, the distribution of brightness derived from the light guide fiber is uneven; and the connection between the light guide fiber and the light emitter requires the rear ends of multiple light guide fibers to be aggregated together and cut at the same head. It will produce a pungent smell of smoke, which is not conducive to environmental protection and the health of the people present;

[0006] 3. The shell is bulky, heavy, and easy to break, which is not only inconvenient for transportation and installation, but also not conducive to cost control and environmental protection; if the whole is assembled in the factory and directly transported to the site for installation, a large number of wooden strips will be used for transportation packaging It is not only bulky and heavy, but also not conducive to environmental protection; moreover, the optical fiber will be bent, bent, and broken to varying degrees during transportation, and the deformation and damage rate is high, which affects the overall appearance; moreover, the wood material The installation of the shell requires another keel frame, which is cumbersome to install and the cost is high

Using the technology provided by this patent document, although the installation of the light guide fiber is simpler, the installation of the pressure spring, the clip and the lock is troublesome: in order to facilitate the installation of the pressure spring, it is necessary to set up enough installation space, a larger installation space The pressure spring is prone to deflection and deformation, especially the insertion and extraction of the light guide fiber will inevitably cause the deflection and deformation of the pressure spring, which will eventually lead to the failure of the clamp to fix the light guide fiber; and, this technology uses the same The light source is supplied through the light guide tube, which still cannot avoid the problem of uneven brightness of the light guide tube at different positions, which also increases the volume of the lamp and takes up a large installation space
