Square hole lamp

Abstract

The invention provides a square hole lamp which comprises a lamp shell. The lamp shell is formed by a bottom plate, an outer ring arranged at the top face of the bottom plate and an inner ring arranged at the top face of the bottom plate. The inner ring is arranged in the outer ring. The inner ring is lower than the outer ring. A light-out hole is formed in the middle of the bottom plate. A face plate, a reflecting cup and a lamp plate are arranged in the inner ring from bottom to top in sequence. A cover plate is arranged at the top of the inner ring in a covering mode. An anti-separating structure which prevents the inner ring and the cover plate from being separated is arranged between the inner ring and the cover plate. The inner top face of the cover plate is provided with a protrusion which abuts against the top face of the lamp plate. A lamp grain is arranged on one side, toward the reflecting cup, of the lamp plate. A light transmission mirror is arranged on the lamp grain in a covering mode. A blocking plate is arranged on the lamp plate in a covering mode. An elastic part is arranged between the top face of the reflecting cup and the lamp plate. The elastic part has action force which drives the reflecting cup and the lamp plate to be separated. The periphery outer wall of the face plate is matched with the inner ring in a sealing mode. The structure is firm, the light condensation degree can be adjusted according to needs, rotating is flexible, and the square hole lamp is very suitable for light casting in a large show place.

Description

technical field [0001] The invention relates to a square hole lamp. Background technique [0002] Square hole lamps are widely used in daily life as a lighting tool. The output beam angle of the square hole lamp is wide or narrow, and the range of variation is between 0° and 180°. The existing square hole lamps have problems such as narrow light projection range, easy structure damage, troublesome correction and adjustment of concentration, and the like. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a square hole lamp, which has a firm structure, can adjust the light concentration according to needs, and can rotate flexibly, which is especially suitable for light projection in large-scale performance venues. [0004] In order to solve the above-mentioned existing technical problems, the present invention adopts the following scheme: the square hole lamp includes a lamp housing composed of a bottom plate, an o...
