LIGHTING PANEL WITH FRONTAL INPUT OF LIGHT EMISSION (OPTIONS) Russian patent published in 2012 - IPC G09F13/00 

FIELD: electrical lighting.

SUBSTANCE: invention relates to lighting panels with a frontal input of light emission and allows to get economical, eye comforting, homogeneous on the radiant surface light panels with LEDs light source to illuminate accommodation and technical premises and to be applied to demonstrational sign-boards, information directories, luminous advertising, medical lighting devices and other lighting devices; the technical result is attained thanks to the lighting panel with a frontal input of the light emission which has a lightguiding panel element and the light emitting source, at that the lightguiding panel element represents a lightguide executed in the shape of a triangular prism, one lateral side of the prism is smaller than the others, at that the emitting light source is located in front of the smaller side of the prism.

EFFECT: enhancement of the cross-sectional evenness of brightness of emerging light beams providing a high coefficient of efficiency upon input-output luminous radiation and securing of the specified direction of emerging beams of light.
