Definitions

  • the invention relates to lighting engineering and can be used to manufacture lighting equipment for general outside, inside and special illumination.
  • Light diodes are an efficient source of light and feature low electric power consumption and long life. Light diodes feature high brightness and small angular size. Light diodes used for light sources without special high-light protection results in considerable visual load, a sense of discomfort and subconsious wish to escape from the operating zone of such lighting device.
  • Defective feature of the known solution is inefficient use of considerable part of the light-dispersing envelope partly used to create ventilation ducts - this is undoubtedly necessary for normal operation of the light diodes, but decreases the light emission area of the lamp.
  • the solution known for light diode cooling system cannot be efficient and most likely has been designed for the lamps producing small light flux, e.g. for decorative lighting and is not suitable for general illumination.
  • a lighting device comprising body with cooling function; light diodes on a circuit board; light dispersing encasement with textured surface in the form of relief lens enveloping the said circuit board; electronic converter located in the body cavity; means of connection with electric circuit (patent CN201106805 , IPC 9 F21 V9/00, published on 27.08.2008).
  • the light diodes are in direct optical contact with light dispersing encasement which is much bigger than the light diode emission surface.
  • the light diode image is blurred, but its reflection is still unbearable.
  • a light diode lamp comprising body with cooling function; source of light located on a circuit board; light emitting encasement enveloping the circuit board with light diodes; electronic converter located in the base to connect with electric circuit (patent W02009087897 , IPC F21S2/00, published on 16.07.2009).
  • a lighting device comprising body with cooling function; source of light located on a circuit board; light emitting encasement enveloping the circuit board with light diodes and coated with luminophor layer; electronic converter located in the body cavity; means of connecting with electric circuit (patent JP2009170114 , IPC F21 S2/00, published on 30.07.2009).
  • the light diodes are in direct optical contact with luminophor-coated surface of light dispersing encasement which is much bigger than the light diode emitting surface.
  • Uniformity of brightness of the encasement surface depends on the uniformity of luminophor particles' arrangement in the coating which is technologically difficult to implement.
  • the engineering result of the invention is improved comfort of illumination, improved uniformity of brightness of the light emitting surface, maintenance of operational temperature of the light diodes.
  • Lighting device comprising body with radiator; light diodes installed to illuminate the first remote emission converter comprising luminophor particles; second emission converter enveloping the first remote emission converter; electronic converter of electric power electrically connected with light diodes; means of connection with electric circuit.
  • Design feature «remote» as applied to specification of the first emission converter is understood as arrangement of luminophor particles at a distance to prevent overheating and deterioration of the generating capacity of the luminophor. It is the Applicant's knowledge that this distance ranges from 6 to 50 mm.
  • the lighting device comprises body 1 with radiator 2; light diodes 3, installed to illuminate the surface of the first optically tansparent encasement 4 fitted with the first means of emission conversion made as luminophor particles; second optically transparent encasement 5 selecting and/or changing direction of the light flux; electronic converter 6 of electric power; means 7 of connection with electric circuit.
  • Fig. 1 shows one of preferred design versions of the lighting device in the form of conventional incandescent lamp having in body 1 cylindric cavity 8, and threaded base 7 for means of connection with electric circuit.
  • Electronic converter 6 of electric power shown by dash line
  • longitudinal guides not shown in Fig. 1 ) on the surface of cavity 8.
  • Fig. 2 shows axonometric drawing of the second version of preferred implementation of the lighting device.
  • First optical encasement 4 and second optical encasement 5 are cylindrical and located along linearly installed light diodes 3 on the surface of body 1.
  • the electronic converter of electric power (not shown in Fig. 2 ) can be outside the lighting device and made as standalone device electrically connected with light diodes 3 and the electric circuit (not shown).
  • Fig. 3 shows axonometric drawing of the third version of preferred implementation of the lighting device mounted on round body 1 with radiators 2 along its perimeter. For illustrative purposes a part of each encasement is shown with a cutout. Light diodes 3 are on the plane of circular body 1, at this, first optical encasement 4 and second optical encasement 5 have spherical surface and are arranged one over the other.
  • the electronic converter of electric power (not shown in Fig. 3 ) can be outside the lighting device as a standalone unit electrically connected with light diodes 3 and electric power supply circuit (not shown).
