Title: LED LIGHTING DEVICE
Abstract:
The invention relates to lighting technology, specifically to LED lighting devices, and can be used in the production of lighting fixtures for various external and internal lighting purposes, and also for lamps with an Edison E-type base. An LED lighting device comprises at least two housings with ribs, in each of which at least one circuit board with at least one light source is mounted, wherein at least one connecting element is mounted between the housings, wherein a housing is interlockingly connected to a connecting element, wherein at least one set of projections and grooves which are complementary to the projections and grooves of the connecting element are formed on the lateral sides of the housing, wherein the connecting element is in the form of a closed cylindrical and internally hollow housing. The technical result is that of simplifying assembly and maintenance; reducing the manufacturing cost of a lighting fixture which does not necessitate the manufacture of connecting elements comprising a large range of products; increasing the reliability of the connection between a housing and a connecting element; increasing heat removal efficiency; permitting fastening to any existing architectural surfaces; permitting the creation of different beam patterns and thereby making it possible for the light-emitting device to be used in different fields of application; extending the area of illumination; and making it possible for elements of the device to be replaced or supplemented during use without the need to remove the device from the surface on which it is mounted.
