Abstract: The ultimate goal pursued by OLED light sources is equivalent to becoming natural light. Since OLED has a spectral distribution equivalent to natural light in a pure state without any treatment, OLED can be said to be an efficient green light source.
1. The spectrum of OLED
Sunlight, OLED, LED spectral distribution
The ultimate goal pursued by OLED light sources is equivalent to becoming natural light. Since OLED has a spectral distribution equivalent to natural light in a pure state without any treatment, OLED can be said to be an efficient green light source.
2, OLED light source test report
testing report
Standard implementation: IECTR62778: 2014 Application of IEC62471 to evaluate the blue light hazards of light sources and lamps. Technical requirements: the true brightness of the lamp L≤10000cd/㎡, the lamp (or the lamp system using the lamp) at any distance does not have a dangerous class of blue light hazards. Test result: L=2892cd/㎡, no dangerous category; individual judgment: actual measured value
The spectrum of common light sources
Among the commonly used indoor light sources, the color temperature is 3000-4000K. It can be seen from the above figure that incandescent lamps (tungsten lamps) and OLEDs are ideal light sources (spectrum). The advantages of incandescent lamps are that they are cheap, but they consume electricity, are easy to generate heat, and have insufficient illuminance. The shortcomings of Some consumers are discouraged.
The author recommends that you choose a good light source for your family, office and study, and you can choose OLED light source for a good price. Its life span is 30,000-40000 hours, and a lamp of one to two thousand yuan is not much money for 10 years a day; of course , The price needs to be considered, you can choose the tungsten lamp appropriately, and appropriately improve the overall brightness of the house (that is, turn on the main lamp + desk lamp).
Care for the eyes, in addition to creating a good light environment and choosing high-quality desk lamps, the most important thing is our eye-use habit, to use our eyes scientifically. After all, electronic products also have a lot of blue light; finally, appropriate outdoor exercise, paying attention to food and work and rest time.
Love eyes, protect eyes, use eyes scientifically, and bathe your eyes in the sun. .
