DESCRIPTION OF THE INVENTION
The invention relates to lighting equipment, in particular to lighting devices, such as chandeliers, table lamps (candelabra) and other lamps with decorative reflecting and refracting, for example, crystal elements. The device is designed for lighting residential premises, cafes, restaurants, churches, hotel rooms and other facilities.
Lighting devices (chandeliers, candelabra) [1.2] are known , containing a tubular holder of the armature with cartridges and lamps and surrounding decorative elements with crystal elements suspended on them, which refract and scatter the light stream emanating from the lamps.
The disadvantages of the analogue are due to the difficulties in giving the scattered light flux a variety of colors.
An illuminating device is known [3] containing a decorative cylindrical holder of a reinforcement with chucks and lamps suspended from the ceiling and coaxially installed one, two or three ring decorative openwork elements with holes on the side walls in which the multi-faceted crystal elements are placed, and crystal elements are suspended, Ambient lamps.
The device [3] chosen as a prototype and does not impart to the scattered light flux a variety of color gamut, i.e. Does not ensure the decomposition into the spectrum of part of the flow to improve the decorative properties, and does not allow us to use a part of the light flux scattered into the upper hemisphere (towards the ceiling).
The object of the present invention is to improve the decorative properties while simultaneously increasing the efficiency of the luminous flux of the lighting device.
The stated aim is achieved in that in an illuminating device comprising an armature holder with at least one cartridge and a lamp and decorative elements with refractive elements refracting the light flux, for example, crystal elements, and the power supplies in said armature are installed and connected to Power supplies, light-emitting semiconductor diodes with lenses whose optical axes are directed to at least a portion of the refractive elements and / or to a selected portion of the decorative elements.
The goal is also achieved by the fact that light-emitting semiconductor diodes are mounted on the surrounding lampholder with a lamp panel in the form of a polyhedron and connected to power supplies.
Achievement of the goal is facilitated by the fact that light-emitting semiconductor diodes are connected to the electronic converter of the supply network, assembled on the valve holder and covered with a decorative element.
Another means of achieving the goal is that a photovoltaic generator (solar battery) is introduced into the armature, made in the form of one, two or more lamps facing the lamp and refracting elements of silicon or from the arsenal of gallium with pn junctions mounted on a panel in the form Polyhedron and connected by external leads to light-emitting semiconductor diodes.
The goal is also achieved by the use of super bright light-emitting semiconductor diodes of different chromaticity with scattering angles in the range 0.3-20 o on the level 0.5 of the maximum radiation power.
The most preferred embodiments of the device according to the invention are shown in the drawings.
FIG. 1 shows a lighting device (chandelier) with a converter of a power supply network or a photoelectric generator, a side view, partially in section
FIG. 2 is the same as in FIG. 1, view AA
FIG. 3 is an optical diagram of the path of the beams of a light emitting diode with a lens and a refractive element mounted in a mandrel of a decorative element of a lighting device
Referring to Fig. 1 and 2, the lighting device is made in the form of a cascade chandelier comprising a tubular reinforcement holder 1 consisting of three hexagonal decorative elements 2, 3 and 4 mounted coaxially with respect to the holder 1 and secured by extensions 5 on the decorative cover 6 of the cartridge 7 with a lamp assembled at the end of the holder 8.
At the opposite end of the holder 1, in the hexagonal decorative cup 9, the power supply 10 is formed, which is an electronic converter of the supply network, and a ring for suspending the chandelier on the ceiling. On the decorative elements 2, 3 and 4, refractive luminous elements are suspended, for example, crystal elements 11 and 12. Crystal beads 12 are suspended in the mandrels of the windows of the decorative elements 2, 3 and 4. In the lighting fixture on the surrounding decorative cover 6 of the panel mounted on its side 13, and having a polyhedron shape, in particular a hexahedron, light-emitting semiconductor diodes 14 are formed with lenses 15 (see Figure 3), the optical axes 0-0 of which are directed to at least a portion of the refractive elements 12 or 11, for example, Every second, third or fourth crystal element. In this case, the radiation beam emanating from the light-emitting semiconductor diode 14 can illuminate the part of the decorative element (mandrel) 2 adjacent to the crystal element 12, as shown in Fig. 3, or can only be directed to the selected part of the decorative element 2, 3 or 4.
The carrier light-emitting semiconductor diodes 14, the panel 13 is made of a flexible foil-coated fiberglass, and the diodes 14 are mounted thereon by a printed circuit board with connection to the power supplies 10.
In the first embodiment of the lighting device, the light-emitting semiconductor diodes 14 are connected in parallel-series chains with ballast resistances (not shown in Fig.) To power supplies 10 made on the basis of the electronic converter of the supply network, current-carrying low-voltage wire 16 installed in the holder 1. When This lamp 8 is connected to the mains by current-carrying wires, and located in the holder 1.
In the second embodiment of the lighting device, a photoelectric generator (solar battery) 17 is introduced into its armature instead of the transducer 10, made in the form of one, two or more lamps facing the lamp 8 and to the refractive elements 11 and 12 of silicon or gallium arsenide plates with pn- Transitions installed at the top of the panel 13 and connected by external leads to the light-emitting semiconductor diodes 14.
As light-emitting semiconductor diodes 14, super-bright semiconductor diodes of different chromaticity (green, blue, red, amber) are used with scattering angles ranging from 0.3 to 20 ° in terms of 0.5 of the maximum radiation power.
Most preferable is the use of super-bright and powerful light-emitting diodes of the firm "HEWLETTPACKAPDGmlH", Germany, the company "NICHIA" Japan or Open Company "Start" Russia. As domestic diodes, it is possible to use light-emitting diodes of the U-164A type; B, D; U-114A, B; U-118A, V. produced by AOOT "Start".
Improvement of decorative properties with simultaneous increase in the efficiency of the luminous flux of the lighting device, mainly in the lower hemisphere, is achieved as follows.
When the device is connected to the mains, the lamp 8 is simultaneously supplied with power and (for the first version), light-emitting semiconductor diodes 14 with lenses 15 that guide super-bright light are connected through an electronic converter 10 of alternating current to a constant or pulsating low-voltage current (9-12 V) Beams of different color for the crystal elements 11 and 12 and / or decorative elements of the reinforcement. Refracting on the faces of the crystal elements (see Figure 3), and partially reflected, the light rays create a color gamut of radiation mixed with the lamp's light flux, thereby improving the decorative properties of the lighting device.
For the second version of the device, when it is connected to the network, the lamp 8 generates a light flux that irradiates the plates of the photoelectric generator 17 (solar battery), based on the phenomenon of the internal photoelectric effect, which creates on the outer terminals of these photo-emf plates. The light-emitting semiconductor diodes 14 with lenses 15 connected to the generator 17 start to generate light of different colors directed to the crystal elements 11 and 12 and / or to the decorative elements of the armature, similar to the one described above for the first embodiment of the device.
The increase in the coefficient of useful use of the luminous flux of the device is due to the possibility of localization and concentration of radiation on the crystal elements that refract and diffuse the light flux in the interior.
The benefits result from the additional and more efficient contribution of the light flux generated by the LEDs to the overall light flux of the device, They have light output, 2-2.5 times higher than incandescent lamps used in chandeliers.
