Description

Lighting device

Technical Field

The utility model relates to the technical field of illumination, in particular to an illumination device.

Background

The projector is a lamp that specifies that the illuminance on the illuminated surface is higher than the surrounding environment, and is also called a spotlight. Generally, it can be aimed in any direction, has a structure which is not affected by climatic conditions, and is mainly used for large-area operation field mines, building outlines, stadiums, overpasses, monuments, parks, flower beds and the like. Thus, almost all large area lighting fixtures used outdoors can be considered as floodlights. The emergent beam angle of the projection lamp is wide and narrow, the variation range is between 0 and 180 degrees, and the beam is particularly narrow and is called a searchlight. The floodlight is a point light source which can uniformly irradiate all directions, the irradiation range of the floodlight can be randomly adjusted, and the floodlight is represented as an octahedral icon in a scene. Floodlights are one of the most widely used light sources in effect map making, and standard floodlights are commonly used to illuminate an entire scene. The main difference between the project lamp and the floodlight is the irradiation angle, the principle and the configuration of the project lamp and the floodlight are basically the same, and under the same power, the project lamp has small irradiation area and long distance; the floodlight has large irradiation area and short distance. A conventional floodlight or floodlight generally includes a housing, a light-transmitting cover, a light source assembly, and a U-shaped bracket. The combination between the light-transmitting cover and the shell is usually realized through an external screw assembly or an external buckle, and the screw assembly and the buckle are exposed outside and are not beautiful and concise in appearance. Also adopt inside buckle structure to combine between the printing opacity of some projecting lamps or floodlight cover and the shell, for example set up the fixture block on the internal surface of printing opacity cover, in the inside screens structure of independent design and fixture block looks adaptation of shell, so, the inside shaping design of shell is comparatively complicated, increases manufacturing cost.
