Definitions
- the invention relates to lighting equipment, namely, to lighting devices with LEDs and can be used in the manufacture of lighting equipment for general outdoor and indoor lighting.
- LEDs are an effective light source, have a low power consumption and a long service life, are characterized by high brightness at small angular dimensions.
- the use of LEDs as light sources without special measures is protected from light glare leads to significant visual stress, causing discomfort and a subconscious desire to leave the room with such lighting devices.
- the process of conversion of electric energy by light emitting diodes into light radiation is accompanied by heat generation.
- the stability of the brightness of the LEDs significantly depends on the temperature of the LED crystal. With increasing temperature, the quantum efficiency of the crystal decreases. The efficiency of LEDs in the operating temperature range depends on the composition of the semiconductor crystal, the emissivity of which remains stable under thermodynamic equilibrium provided by the design of the cooling device.
- thermodynamic equilibrium becomes more acute the more powerful luminous flux you need to get to create a normalized illumination. This problem becomes especially relevant when using LEDs in luminaires designed to create general lighting.
- the task of ensuring the thermal balance of the LED is solved by heat removal, in particular, using cooling radiators.
- the process of heat exchange of the surface of the radiator with the atmosphere is carried out mainly by radiation and convection. Heat transfer efficiency is determined by many factors, but more often total - the value of the heat exchange surface area and its configuration.
- LEDs enclosure with limited air access.
- the presence of a fan reduces the reliability of the structure as a whole and complicates its assembly.
- Transparent narrow light diffusers have, firstly, a small light-emitting surface, and secondly, they transmit bright light emitting diodes almost unchanged, creating light discomfort for the observer.
