PAINTING LAMP Russian patent published in 2022 - IPC F21L14/00 

FIELD: construction industry.

SUBSTANCE: invention relates to means of detecting defects in the surfaces of walls, floors and ceilings and can be used to improve the efficiency of preparatory and finishing works in construction. The painting lamp consists of a sealed housing, inside which an electric driver is installed to supply energy, and glass is installed on the housing from the side of the emitted light stream. One source of narrowly directed light consists of an LED and a lens, the end surfaces of which have the shape of concave paraboloids of rotation. The lens forming part consists of a convex parabola located between two straight segments forming reverse conical surfaces, while inside the lens there is a cavity for placing an LED, bounded at the ends by two concave paraboloids of rotation connected by an ellipsoid of rotation, in addition, upper and lower covers made of silicone rubber are installed at the ends of the housing.

EFFECT: ensuring the ability to effectively distribute light over a controlled surface, which facilitates the detection of defects, contributes to a significant reduction in labor intensity and improves the quality of work of painters and finishers.
