Abstract
Description
- 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.
- Many countries have introduced blindness measure standardizing impact of bright sources of light on human vision. Most frequently this problem is solved by dispersing the light flux from a light source by different means, frequently combining both protective-decorative functions and light dispersion function. An other avenue of attack on the problem is to distribute primary emission over extensive surface whose brightness does not cause discomfort and is sufficient to produce normalized level of illumination.
- On the other hand, transformation of electric power by light diodes into light emission is attended by heat generation. The brightness maintenance factor of light diodes notably depends, at that, on the temperature of light diode crystal. Quantum efficiency of the crystal decreases with increase of temperature. The problem of establishing thermodynamic equilibrium is the more important the more powerful is the light flux required for normalized illumination. The problem is especially topical when light diodes are used in equipment intended for general illumination.
- Known is an device comprising body; source of light installed on a circuit board; optically transparent plate comprising lumiphor particles and installed before the source of light; light dispersing enclosure enveloping the said plate; electronic converter; means of connection with electric circuit (petent
US2009141474 , IPC9 F21 V9/160, published on 04.06.2009). - 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. In the applicant's opinion 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.
- Known is 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 , IPC9 F21 V9/00, published on 27.08.2008). - In the known solution the light diodes are in direct optical contact with light dispersing encasement which is much bigger than the light diode emission surface. In the oberver's line of vision the light diode image is blurred, but its reflection is still unbearable.
- Known is 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). - Known is 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 - In the known solution 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.
- The invention is specified by the following combination of essential features:
- 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.
- For additional and developing features it is necessary to point out the following:
- the body may have cylindrical cavity;
- the radiator of the body can be made as longitudinal and/or transversal cooling fins with total surface area dependent on the amount of heat generated by the light diodes. To intensify cooling the longitudinal fins can be made on the inner cylindrical surface of the body;
- cylindrical surface of the body cavity can additionally have at least two longitudinal guides to install the ciruit board of the electric power electronic converter;
- to produce light emission it is possible to use light diode crystals to generate indigo emission which is subsequently transformed by the luminophor particles to regulate spectral characteristics of emission;
- to produce light emission it is possible to use diodes producing white light flux with color temperature more than 6000 K, in which the indigo component can be converted by the first remote converter into emission with different wavelength, making possible to correct color characteristics of the resulting light flux;
- the light diodes can form a cluster, and can be arranged on the plane linearly or regularly;
- the luminophor particles of the first remote emission converter are on the surface and/or in the material of the first optically transparent encasement installed at a distance from the light diodes and made, e.g. from polycarbonate or polymethyl methacrylate;
- the first remote emission converter can comprise luminophor particles of the same illumination color or luminophor particles of different illumination color, depending on desired spectrum of total light emission;
- the first remote emission converter can comprise long after-glow luminophor particles, this makes possible to use such a ligh-diode lamp to create emergency or escape illumination;
- the second emission converter selecting or changing emission direction made as a totality of elements on the surface and/or in the material of the second optically transparent encasement enveloping the first optically transparent encasement and distant from it and made, e.g. from polycarbonate, polymethyl methacrylate or glass;
- for the element transforming the emission direction in the second converter it is possible to use a relief element on the surface of the second optically transparent encasement, e.g. a set of regularly arranged small lenses;
- for the element of the second emission conveter it is possible to use disperse phase of substance with high reflectance and integrated with material of the second optically transparent envelope;
- the first and the second emission converters can be combined in one structural member made as an optically transparent encasement enveloping the light diodes, the wall thickness of such an encasement should be sufficient to efficiently disperse the light flux emitted from the surface of the encasement;
- for the element of the second emission conveter it is possible to use metal oxides integrated into the material of the encasement made of glass to form an optical filter;
- the electronic converter of electric power can be located both inside and outside the device. Design of such a conveter is of no principal importance. Important for the output electric specifications of such a converter is to provide for light diode operation and to meet design specifics of lighting device implementation.
