Definitions

  • the invention relates to lighting technology, specifically to LED lighting devices which are intended for producing external and internal lighting.
  • lighting devices shall not create glaring light, sudden jumps in brightness of the radiation surface, which may cause a feeling of discomfort.
  • the mentioned effect results from a high level of brightness of the radiation source and its small angular dimensions. Most often this problem is solved by scattering the radiation using various means which mostly combine both protective-decorative functions and light scattering functions.
  • the other way of approaching the mentioned problem is to distribute the primary radiation over the large light-radiating surface the surface brightness of which does not cause discomfort and is sufficient for establishing a standard lighting level.
  • the method of prior art has features similar to those of the invention and describes the manufacture of mercury-discharge lamps with corrected chromaticity.
  • the application of luminophore particles to the internal surface of the enclosure has been dictated by the need to correct the spectrum of radiation produced by gas discharge.
  • the method of prior art is energy- and labor-intensive process, besides associated with environmentally hazardous actions when measuring mercury in the cylinder of the gas-discharge light source.
  • a method for producing a large light-radiating surface which comprises the generation of the radiation stream by a plurality of single sources each of which directs the radiation stream to the space angle; use of the stream to irradiate the surface element of the luminescent coating applied to the plate from the optically transparent material; transformation of the wavelength of the radiation part by luminophores; radiation of the direct radiation stream and transformed radiation stream from the surface element dS of the plate; integration of the elementary streams of light from the whole light-radiating surface S of the plate (RF patent No. 2301475 , IPC H01063/06 issued on June 20, 2007).
  • the method of prior art has been aimed at producing a uniform light intensity of the large planar surface.
  • a light emitting diode (LED) has been used as a single radiation source in the method of prior art.
  • the LED radiation scattering occurs in the luminophore layer, on which the area of the irradiated surface dS is determined by the value of the space angle d ⁇ . After scattering of the incident radiation the surface brightness of the area dS remains non-uniform and decreases as the distance from LED optical axis increases, which results in a non-uniform luminous exitance of the whole light-radiating surface S.
  • the precorrection of the radiation source distribution using a lens involves a rise in the cost of led-emitting diodes, complication of the lighting device manufacturing and is not always economically feasible.
  • the disadvantage of the prior art method is a non-uniform luminous exitance of the light-radiating surface conditioned by the decrease of brightness as the distance from the axis of the radiation beam incident on the irradiated surface increases.
  • the use of the plate limits substantially the possible scope of application of prior art appliance.
  • a light-radiating appliance comprises a light-emitting diode (LED) source of light in the ultraviolet range of the spectrum and a planar body made from an optically transparent resin and containing dispersed luminophore particles and light-storing bodies together with light-transmitting inorganic particles (RF patent No. 2319063 , IPC F21V9/00 issued on June 10, 2006).
  • LED light-emitting diode
  • the disadvantage of the prior art solution is the allocation of radiation sources in a narrow enclosed tube, which limits the selection of the light-radiating surface form.
  • the prior art assembly is intended to be used with low-power LEDs and is not capable of creating the light level required for general lighting.
  • a lighting assembly comprising a housing, means for connecting with a source of electric power; a series of light emitting diodes mounted within the housing and sufficient in output wavelength for excitation of luminophore receptive to an ultra-violet region of the electromagnetic spectrum; electric power transforming means to convert power into a known voltage for use by said light emitting diodes; a transparent plate having an interior surface area covered with luminophore, through which a light excited by luminophore and visible to the naked eye is transmitted ( U.S. patent No. 6068383 , IPC E2158/04, issued on May 30,2000).
  • the disadvantages of the known analogue are losses of a light stream which is emitted by the light emitting diodes sideways from the optical axis, as well as a non-uniform exitance of the light-radiating surface conditioned by a decreasing intensity of the stream of light incident on the irradiated area as the distance from its optical axis increases and by a lack of means for smoothing the surface brightness of the light-radiating surface and the irradiance color.
  • the technical results of the invention are increases in uniformity of radiation color and in surface brightness of the light-radiating surface, enhancement of processing capabilities for designing lighting devices with that kind of surface.
  • the alternative form of the method provides the change in the sequence of transforming the radiation stream whereby first the wavelength of the LED radiation stream is transformed, and then the direction of the radiation stream is established by the surface of the light-reflecting structure.
  • the change in the sequence of transforming the LEDs radiation has no influence on the claimed technical result.
  • a first means for transforming the stream of radiation shall be understood to mean a plurality of luminophore particles the spatial arrangement of which is determined by the configuration of that part on the surface or in the volume of which are contained said particles.
  • substrate is meant by the applicant to be understood as a detail of design made from optically transparent material capable of establishing both rigid and flexible surfaces;
  • the lighting device ( Fig.1 ) comprises a light-emitting diode (LED) emitter 1 located on the board 2, a light-reflecting structure 3, a planar substrate 4 located at distance h1 from the light-reflecting structure 3 and equipped with the first means for transforming the radiation in the form of luminophore particles 5 applied to the surface of the substrate 4, the second means for transforming the radiation in the form of the plate 6 located at distance h2 from the planar substrate and equipped with a patterned surface 7.
