Abstract

The invention discloses an illuminating device. The illuminating device comprises a light source assembly and a masking plate sequentially arranged from top to bottom, wherein the light source assembly comprises a first base plate, and a plurality of light sources are also arranged on the bottom surface of the first base plate at intervals; the masking plate comprises a second base plate, a plurality of openings are formed in the top surface of the second base plate, each light source corresponds to the center of one opening, a side plate extending towards the light sources is also arranged on the edges of the openings, an inclined angle between the side plate and the second base plate is larger than 90 degrees, a gap is arranged between the side plate and the first base plate, and the whole second base plate is a convex surface. Light emitted by the light sources and radiated in a non-illuminating region is reflected back to an illuminating region by the illuminating device provided by the invention. Meanwhile, the illuminating device can recycle the light sources and reduce illuminance loss and further has an anti-dazzling function.

Description

technical field [0001] The invention relates to the field of lighting fixtures, in particular to a lighting device. Background technique [0002] At present, there are many lighting devices on the market, and there are various types of light sources used in the lighting devices. Traditionally, incandescent lamps are used. Because light-emitting diodes have energy-saving, power-saving, and environmental protection effects, as the technology becomes more and more stable, there has been a tendency to gradually replace traditional incandescent lamps in recent years. [0003] However, light-emitting diodes are directional light sources, and the opening angle of directional light sources is small. It is necessary to use a reflector to increase the light opening angle, and then use a diffuser to soften the light. Whether it is a light-emitting diode or other For light sources, the brightness will gradually decrease due to the larger the opening angle of the light source. [0004]...
