Cold light source meaning
In the process of conversion of electrical energy to light energy, relying on the electronic principle and the role of fluorescent powder, only a very small amount of heat energy, will be converted to more electrical energy into light light source, such as: fluorescent lamps, energy-saving lamps. Cold light source of electric light energy conversion rate is high, is the universal energy vacuum incandescent lamp 6 times. The disadvantage is that the luminous body is large, can not be through the reflector spotlight (HID high-pressure xenon lamp is a cold light).
1. Thermal light source: the use of heat-excited light source (incandescent lamps, arc lamps, tungsten halogen lamps, etc.), sunlight is a typical.
2. Cold light source: the use of chemical energy, electrical energy to stimulate the light source (fireflies, neon lights, three-color lamps, etc.). Cold light source is following the incandescent lamp, LED, LCD light source products after the emergence of new high-tech light source, because of its light-emitting principle is under the action of the electric field, resulting in electron collision excitation of fluorescent materials to produce light-emitting phenomena, with very good optical properties and relatively high luminous efficiency. Cold light source work basically does not heat, to avoid a series of problems related to the accumulation of heat.
Cold light source lamp
Cold light source lamp is following the incandescent lamp, LED light source products after the emergence of new high-tech light source. Cold light source lamp light-emitting principle is under the action of the electric field, resulting in electronic collision excitation of fluorescent materials to produce light-emitting phenomena. Has very good optical, variable flash characteristics. Cold light source does not generate heat when working, avoiding a series of problems related to the accumulation of heat. Cold light source lamp is almost all of the other energy into visible light, other wavelengths of light is very little, while the hot light source is different, in addition to visible light and a large number of infrared light, a considerable portion of the energy into the illumination does not contribute to the infrared light. Hot light source plus infrared filter out of the light should be almost the same as the light emitted by the cold light source, because the infrared light has been filtered out. Light-emitting diodes are now being developed as a cold light source with a long life and soft light, a light source that is expected to replace the electric light bulb. Generally in large wine cellars and private wine cellars, cold light source lamps will be used as the main lighting tools, due to incandescent lamps will produce heat; fluorescent lamps produce a large number of invisible ultraviolet rays, ultraviolet rays seriously damage the structure of the wine body, so can not be used as a wine cellar lighting source. The only cold light source is the most suitable light source for red wine cellar.
Benefits of cold light source
LED is also a cold light source, the first moonlight brand multi-functional cold light - the use of the basic material itself light source, under the action of the electric field is stimulated to emit light, the light-emitting layer is not in direct contact with the power supply, so the reflective layer is not hot, belonging to the "cold light source". "Cold light source", at the same time does not produce heat radiation, does not produce environmental pollution. As the power supply is excited light, power supply without circuit, so the power consumption is extremely weak, energy-saving effect is quite.
The above is what I want to tell you the benefits of cold light source Oh, there is no cold light source of knowledge is far more than you know much more? As long as we pay attention to observe, will find that the cold light source in our daily life everywhere, we must live with the lights can not do without it, the hospital's medical equipment can not do without it, in our future life, even more can not do without it. So the cold light source in our life plays an extremely important role. After this with the editor together with the cold light source of learning and understanding, we have not felt benefited greatly, used for life?
