Abstract
Description
Technical Field
[0001] This utility model relates to the field of stage lighting technology, and more specifically, to a stage light with a metal mounting base. Background Technology
[0002] In the field of lighting technology, light guides are generally used to mix light evenly in order to achieve uniform light mixing. Light is reflected inside the light guide to achieve a uniform light mixing effect, forming a beam of light with uniform brightness and color. To prevent the light guide from falling off during the rotation of the lamp, a fixing bracket is usually used to fix the light guide. However, in the existing technology, the fixing brackets are mostly made of plastic. The environment where the light guide is located is a high-temperature environment inside the stage lamp. The plastic fixing bracket will release a variety of decomposition products under the influence of high temperature. The decomposition products adhere to the surface of the light guide, resulting in poor light effect. Moreover, the decomposition products are not in line with environmental protection requirements. Utility Model Content
[0003] To overcome at least one of the defects described in the prior art, this utility model provides a stage light with a metal mounting base, solving the problem of high-temperature precipitation of pollutants from traditional plastic light guide brackets, which contaminate and adhere to the surface of the light guide and other optical effect components, thereby affecting the light efficiency.
[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a stage lamp with a metal mounting base, including a lamp head that accommodates a light source, the outside of the lamp head being pivotally connected to a support arm, the support arm being pivotally connected to a base housing, a light guide and a metal mounting bracket being provided in the direction of the light beam emitted by the light source, the mounting bracket having a through hole along the direction of the light beam emitted by the light source, the light guide being inserted into the through hole, and also including an elastic retaining member disposed in the mounting bracket to prevent the light guide from shaking.
[0005] The stage light emits a high-brightness beam by setting up a light source inside. After the high-brightness beam enters the light guide, the uniformity of the light spot is improved. The light guide is supported by a metal mounting bracket. Even if the high-brightness beam generates a lot of heat when passing through the light guide, the metal mounting bracket will not be affected by the high temperature, nor will it decompose and release decomposition products. This avoids the situation where plastic decomposition products adhere to the light guide, eliminating the generation of non-environmentally friendly substances. At the same time, the light guide will not be affected by pollutants that reduce light transmission efficiency, ensuring the light beam's transmittance and improving the environmental performance of the stage lighting fixture.
[0006] Furthermore, the light guide includes two elastic retaining members, which are arranged sequentially along the beam direction. The two elastic retaining members ensure the stability of the light guide and prevent shaking.
[0007] Furthermore, the inner wall of the mounting bracket has a stepped recess, and the elastic retaining member is disposed on the stepped surface. The stepped structure has a simple design and provides positioning and limiting functions, guiding the installation of the elastic retaining member.
[0008] Furthermore, the elastic retaining element is an elastic ring, with its inner side abutting against the light guide and its outer side abutting against the step sidewall. The elastic ring possesses certain elastic deformation characteristics, serving as a fixing bridge between the light guide and the step sidewall, continuously providing adaptive adjustment force to accommodate installation errors during assembly.
[0009] Furthermore, the elastic retaining element is a scaling wave ring, with the troughs of the scaling wave ring abutting the light guide and the crests of the scaling wave ring abutting the sidewall of the step. The scaling wave ring has a large elastic coefficient, which enhances the tightness of contact between the light guide and the step.
[0010] Furthermore, it also includes a clamping seat disposed on the mounting bracket. The bottom end of the clamping seat abuts against the end of the elastic retaining member away from the light source to fix the elastic retaining member, and a first light-transmitting hole is provided corresponding to the light guide. The clamping seat abuts against the elastic retaining member and prevents it from falling off, while the first light-transmitting hole allows the light beam to pass through.
[0011] Furthermore, both the elastic retaining element and the clamping seat are made of metal. Metal is heat-resistant, preventing the release of contaminants under high-temperature conditions.
[0012] Furthermore, it also includes an optical effect sheet covering the first light-transmitting hole. The end face of the clamping seat away from the light source has a recessed receiving groove, and the optical effect sheet is placed in the receiving groove. The cooperation between the light guide and the optical effect sheet enhances the artistic expression of the stage lighting, and the receiving groove can accommodate the optical effect sheet and provide positioning guidance for its installation.
[0013] Furthermore, the optical effect sheet is a fogging sheet. The fogging sheet helps to diffuse the light beam and improve its uniformity.
[0014] Furthermore, it also includes a fixing sleeve fitted over the mounting bracket, the end of the fixing sleeve abutting against the clamping seat, and a second light-transmitting hole corresponding to the light guide. The fixing sleeve can fix the clamping seat and prevent the clamping seat from falling off. Attached Figure Description
