Description

Stage lamp with stable light-homogenizing device

Technical Field

The utility model relates to a technical field of stage lamp, more specifically relates to a stage lamp with firm even light device.

Background

The LED chip generally needs to be used in cooperation with the light guide body, and light emitted by the LED is reflected for multiple times inside the light guide body to achieve a uniform light mixing effect, so as to form a light beam with uniform brightness and color. In the conventional light guide, an integrally arranged light guide is usually placed in a through hole of a fixed seat, an atomization sheet positioned on a light emergent surface of the light guide abuts against a step on the fixed seat, and the light guide is locked with the fixed seat by locking a cover body, so that the light guide is prevented from falling off in the working process. Such fixed mode requires very high to the stability of being connected between lid and the fixing base, because in case unexpected loosen between lid and the fixing base, will make the light guide body roll-off fixing base, causes the light guide body to damage other components inside even the lamps and lanterns.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming above-mentioned prior art's at least one defect, provide a stage lamp with firm even light device, be used for solving the problem that the light conductor is unexpected to drop easily in the course of the work.

The utility model adopts the technical proposal that: the utility model provides a stage lamp with even light device stabilizes, include the lamp plate, have the light conductor that goes into plain noodles and go out the plain noodles and will the light conductor is fixed in fixed subassembly on the lamp plate, fixed subassembly is including being used for the centre gripping the fixed section of thick bamboo of light conductor, fixed section of thick bamboo runs through along its length direction and has and be used for holding the through-hole of light conductor, fixed section of thick bamboo is kept away from the terminal surface of lamp plate is to being close to the lamp plate direction is provided with and runs through the tensioning groove of through-hole lateral wall, the light conductor is close to the one end of going out the plain noodles with through-hole interference fit.

Through fixed section of thick bamboo is kept away from the terminal surface of lamp plate sets up the tensioning groove makes a terminal surface of fixed section of thick bamboo has certain elasticity, will the light conductor is along being close to the direction of lamp plate inserts behind the through-hole, thereby the tensioning groove provides certain tensile force and makes the light conductor with interference fit is realized to the through-hole. The fixing cylinder enables the light guide body to be firmly installed in the through hole in a clamping mode, the fixing mode has high stability, the light guide body is not prone to falling off in the working process, and the tensioning groove is simple in structure and easy to machine.

Furthermore, a plurality of first ribs for fixing the light guide body are arranged in the through hole, the first ribs extend along the length direction of the fixed cylinder, and the through hole is in interference fit with the light guide body through the first ribs. The first ribs are arranged to press the light guide body tightly, so that the contact area of the fixed cylinder to the light guide body is reduced, the pressure of the fixed cylinder to the light guide body is increased, and the light guide body is matched with the fixed cylinder more tightly.
