Description

lighting device

'TECHNICAL FIELD

The invention relates to a lighting engineering and can be used in the manufacture of lighting equipment for general outer, inner, and special lighting.

'BACKGROUND OF THE INVENTION

LEDs are efficient light sources have low power consumption and long service life. LEDs have high brightness at small angular size. The use of LEDs as light sources without special protection from the glare of light results in significant visual stress, causing discomfort and subconscious desire to get out of the scope of such lighting devices.

In many countries introduced a special glare factor, normalizing the permissible degree of impact on human eyesight bright light sources. Most often, this problem is solved by scattering the light flux from the radiation source through various means, often combining both protective and decorative functions, and the functions of light dissipation. Another way of solving this problem is the distribution of the primary radiation over the large surface, whose brightness will not cause discomfort, and be sufficient to produce the rated lighting level.

On the other hand, the process of converting electrical energy to LED light emission accompanied by the release of heat. Thus the stability of the luminance of LEDs depends markedly on the temperature of the LED chip. With increasing temperature the quantum efficiency of the crystal is reduced. The problem of creation of thermodynamic equilibrium, it becomes more important than the more powerful light output are required for the creation of standardized illumination. Particularly acute this problem becomes when using LEDs in equipment intended for general lighting.

It is known a lighting device comprising a housing; a radiation source disposed on the board; an optically transparent plate provided with phosphor particles and arranged in front of the radiation source; diffusing shell covering said plate; electronic converter; means for connecting to an electric circuit (patent US2009141474, IPC 9 F21V9 / 160, published

04.06.2009).

The disadvantage of this solution is

inefficient use of significant portion of the surface of the diffuser shell, which is partly used to create ventilation channels which are needed to be the

normal operation of the LEDs, but at the same time reduce the emission area of ​​the lamp. LED cooling system in the prior art, according to

the applicant can not be effective and, most likely intended for the lamps, creating a small light output, for example, for illumination purposes and is not suitable for general lighting.

It is known a lighting device comprising a housing with a cooling function; LEDs are placed on board; diffusing shell provided with a structured surface relief lenses, covering said board; electronic converter disposed in the body cavity; means for connecting to an electric circuit (patent CN201106805, IPC 9 F21V9 / 00, published 27.08.2008).

In the known solution, the LEDs are in direct optical contact with the diffuser shell, which is considerably more LED radiation surface. On the line of sight of the observer of the LED image will be blurred, but the display is still unbearable.

Known LED lamp, comprising a housing with a cooling function; a radiation source,

placed on board; light-emitting shell covering the LED board; electronic converter disposed in the base for connection to an electrical circuit (patent WO2009087897, IPC

F21S2 / 00, published 16.07.2009). 90 is known a lighting device comprising a housing with a cooling function; a radiation source disposed on the board; a light emitting envelope, enclosing the LED board and covered with the phosphor layer; electronic converter arranged

95 in the body cavity; connection means

an electrical circuit (patent JP2009170114, IPC

F21S2 / 00, published on 30.07-.2009).'

In the known solution, the LEDs are in direct optical contact with the coated

100 phosphor surface of the diffuser shell, which is considerably more povorhno'sti LED radiation. Brightness uniformity shell surface depends on the uniformity of 'the location of the phosphor particles in the coating, which is difficult to

105 technologically provide.

: The technical result of the invention is to increase the comfort of lighting / brightness uniformity improving the light emitting surface, providing a working temperature of the LEDs.
