LIGHT-EMITTING DIODE (LED) LIGHTING FIXTURE AND HEAT-ELIMINATING PROFILE AS FIXTURE BODY Russian patent published in 2014 - IPC F21S8/00 

FIELD: electricity.

SUBSTANCE: group of inventions which includes a LED lighting fixture and a heat-eliminating profile as its body is related to the field of lighting engineering and namely to lighting fixtures for stationery mount with use of semiconductor optical point sources (LEDs) located in a row or a band and its body included into the device composition and serving as a load-carrying member. Substance of the invention lies in combination of lighting, load-carrying, protective and heat-eliminating functions which are attained due to manufacture of the lighting fixture with a body-radiator with linear printed circuit boards and optical point sources installed on it, translucent screen made of shock-proof material, end covers and external power supply source located at the external side of the body base. The lighting fixture is distinguished by use of heat-eliminating extruded section as a body-radiator and peculiarities of its design allow assembly of the lighting fixture with the least labour intensity due to availability of U- and F-shaped longitudinal elements in its base and improved heat elimination due to availability of longitudinal elements formed by closed loops. Optical sources are made in the form of several lines of printed-circuit boards with certain amount of optical sources on them. Protective translucent screen is flat and has rectangular shape. End covers are made from the inner side as the body counterpart thus ensuring accurate mount during installation and due to vertical-oriented openings for fixtures mounting of the lighting fixture can be made in the assembled condition.

EFFECT: improving operational characteristics due to structure of load-bearing profile of the lighting fixture and namely improving heat elimination from linear boards with optical sources; reducing costs for manufacture and assembly of components; simplifying mounting of the device.
