The technical field.
The invention refers to the lighting equipment, namely to led lighting devices, designed to create external and internal lighting.
Prior art.
To improve ergonomic indicators of the lighting device shall not cause the blinding glare, sharp changes in brightness of a surface radiation, causing discomfort. The effect is a consequence of the high brightness of the light source and its small angular size. Most often, this problem is solved by means of radiation scattering by various means, often combining both protective and decorative features and functions of the scattering of light. High brightness high-power LEDs associated with the release of heat energy produced in the course of nonradiative recombination of electrons and affects the stability of the emissivity of the crystal (Festubert, "LEDs", M FIZMATLIT, 2008, p.58-59) and on the phosphor placed in the immediate vicinity. Exceeding the permissible heat load leads to temperature extinguishing and phosphor degradation and lifetime (http://ru.wikipedia.org/wiki/Luminescence).
Another way of solving this problem is the distribution of primary radiation over a vast light-emitting surface, surface brightness which does not cause discomfort, is sufficient to create a standard lighting level and allows you to create operating temperatures for the components of the lighting device.
The known method create a large light-emitting surface, including the generation of the light flux radiation source that contains ultraviolet component; the impact of this flow on phosphor particles, the bearer of which is the inner surface of the ellipsoidal shell made of optically transparent material; phosphor conversion of ultraviolet radiation into visible light red region of the spectrum; the direct radiation and converted flows radiation from the external surface of the shell (Tshwanetse and others, "Electric light sources, Gosenergoizdat", Moscow, 1957, s).
There is a method is similar to the invention of the signs and describes the work of the mercury discharge lamps with a fixed color. The use of phosphor particles associated with the shell caused the need of correction of radiation spectrum. The shape of the shell, which is a carrier of phosphor particles, due to the need to reduce thermal effects of radiation source on the structural elements of the lamp, in particular, on the phosphor and the glass shell. The known method is energy - and time-consuming process, besides involving hazardous operations dosing of mercury in the container of gas-discharge light source.
Known way to create a large light-emitting surface, including the generation of radiation flux set single sources, each of which directs the radiation flux in the solid angle; the impact of this flow on the surface feature fluorescent coating deposited on the plate of the optically transparent material; conversion wavelength part of the radiation phosphor; radiation and direct converted flows a source of radiation from the surface dS plate; integrating elementary light streams from the entire light emitting surface S plate (patent RF №2301475, IPC 01J 63/06, publ. 20.06.2007).
Known solution is aimed at creating a uniform brightness of vast, flat surface. As a single source of radiation in a decision to use the led. Scattering of radiation led happens in the phosphor layer, the area irradiated surface dS which is determined by the solid angle dQ. And after scattering of incident radiation surface brightness site dS remains uneven and decreases as the distance from the optical axis of the led, which leads to uneven luminosity of light-emitting surface S. Preliminary adjustment of the distribution of the radiation flux through the lens increases the cost of LEDs, and complexity of the production of lighting devices and not always economically justified.
A device to create a large light-emitting surface, containing case; source radiation, placed inside the body; plate of optically transparent material, placed in front of a light source and is equipped with a phosphor coating (RF patent №2301475, IPC 01J 63/06, publ. 20.06.2007).
A shortcoming of this solution is the inequality in the luminosity of light-emitting surface due to decreasing brightness as the distance from the axis of the beam incident on the irradiated surface. In addition, plate, significantly limits the possible applications of the known device.
Known patent that describes the light emitting device that includes an led light source ultraviolet region of the spectrum and planar body, made of optically transparent resin containing distributed particles phosphor and light gathering substances together with the light of inorganic particles (RF patent №2319063, IPC F21V 9/00, publ. 10.06.2006).
By virtue of the known solution is, invisible to the observer of the radiation source. The disadvantage of this solution is possible to note the constructive complexity of multicomponent panel, which manufacturing is a complex technical problem and, most likely, which is expensive product. In addition, declared in the description power light 15,5 CD/m 2 is manifestly insufficient for creating lighting devices intended for General lighting.
A device for General and local lighting, containing LEDs ultraviolet radiation, located on the axis optically transparent tube on the surface of which is coated with the layer of phosphor converts the invisible radiation in visible light (patent № JP 2002133910, MKI F21S 8/04, published 10.05.2002).
A shortcoming of this solution is the placement of the sources of radiation in a narrow closed at the ends of the pipe, which limits the choice of the form of light-emitting surface.
In addition, from the LEDs in the pipe is difficult to remove heat and overheating of LEDs reduces their svetoizluchateli ability. Most likely there is a construction designed to use low-power LEDs and not able to create the light level required for General lighting.
Famous lighting system, containing a body, means of connection to the power supply; the number of light-emitting diodes are installed inside the case and emitting a wavelength of the excitation of phosphor, sensitive to ultraviolet region of the electromagnetic spectrum; conversion tool voltage for use of these light-emitting diodes; transparent plate with internal surface and coated with phosphor, through which passes a Horny phosphor light visible to the naked eye (US patent №6068383, MKI F21S 8/04, publ. 30.05.2000).
The disadvantage of analog are the loss of luminous flux emitted by the led in the hand from the optical axis, and non-uniform luminance of the light emitting surface due to decreasing brightness incident exposed the shallowness of the luminous flux as the distance from the optical axis and the lack of alignment of the surface brightness light emitting surface and color of a luminescence.
The technical result of the invention is increasing the uniformity of color and brightness light emitting surfaces, reduction of thermal effects on phosphor and expansion of technological possibilities for designing lighting devices.
