The light-emitting diode lighting device relates to lighting engineering and is intended for use in lighting design, architectural illumination and outdoor and indoor lighting. The technical result is a wider variety of lighting devices, more uniform luminous intensity of an elongate light-emitting surface, greater manufacturability of the design, improved use of the light beam aperture, and improved cooling of the sources of radiation. The invention comprises a longitudinal profiled body having a base surface and a reflecting surface, light-emitting diodes disposed along the reflecting surface, a light diffuser secured to the body, and a power supply, wherein the optical axis of the light-emitting diodes is oriented at an angle psi to the base surface and a means for converting radiation with a wavelength lambda1 into radiation with a wavelength lambda2 is disposed between the light-emitting diodes and the light diffuser, said means being in the form of particles of a luminophore situated on the surface and/or in the material of a longitudinal envelope with an arcuate cross-section which is fastened to the reflecting surface. |
