UIV OLED lighting source characteristics, understand the different light - China lighting network

OLED（ 有机发光二极管) Organic light-emitting diodes (oleds). Unlike the LED material, OLED is surface light source, soft, lightweight, low energy consumption, less heat, no blue, close to natural light. In addition, OLED with different substrate, can be made into a transparent, flexible, such as new shape, can break through the current design of the limitations of lamps and lanterns, can apply to more fields. OLED OLED the basic structure of the main structure is composed of a thin and transparent semiconductor properties of indium tin oxide ( ITO) , connected to the power of the anode, plus another metal cathode, package into such as sandwich structure. The whole structure layer includes the hole transport layer ( HTL) , the light emitting layer ( EL) With the electronic transport layer ( ETL) 。 When the power supply to the appropriate voltage, the anode hole charge will be in the light emitting layer and cathode, produce light, according to its different formula to produce red, green and blue RGB trichromatic, constitute a basic color. OLED characteristic spectrum close to natural light spectrum Sunlight, OLED, LED light has become an essential part of People's Daily life, OLED light source, the pursuit of the ultimate goal of is equivalent to become natural light. Because of the OLED in without any processing pure state equal to the spectral distribution of natural light, so the OLED can be said to be a highly efficient green light source. OLED characteristics of light ( 0. 88mm） OLED surface light compared with the thickness of the LED tube light OLED lighting panel thickness is only 0. 88mm。 Because of its ultrathin, super light, low power consumption, can be used as a surface light source, OLED has wide potential applications. OLED future applicable areas such as the window or skylight, wall and ceiling, which has the function of lighting, floor, stair, mirror and other almost infinite possibilities. OLED lighting environmental protection, no mercury, is the next generation lighting ideal material. Flexible Flexible OLED Flexible OLED characteristics unique characteristic of Flexible OLED light source Flexible ( Flexible flexible) , increased the design according to the features of flexible elasticity and the imagination, a variety of features make OLED lighting and LED to the differentiation, the preference of surface light source lighting market. It can be used to design unique, creative, decorative lamps and lanterns, is different. OLED characteristics no harm of blue OLED spectrum, high-energy blu-ray ( 450海里) Close to natural light blue, 450海里) Is a kind of high-energy visible light, can be directly through the cornea and lens, direct the macular area, accelerating the macular area cell oxidation, chemical damage to the retina, blu-ray retinal damage is more serious for children, and blue light is everywhere, a lot of exists in the daily life, the sun, fluorescent tubes, computer, LCD all contain blue light. Thus, blu-ray ( HEV） Confirmed by research is one of the most dangerous visible light. OLED spectral analysis and testing, confirmed that OLED light no harm of blue light, is the ideal health lighting light source, especially for the desk lamp that shield an eye visual homework, improve the operation of light environment, care for eye health. OLED show refers to the characteristics of high ( Ra≥90） OLED compared with traditional conventional leds show a color rendering index ( Ra） Also known as color rendering, is refers to the extent of the light source color rendering for object. Color is one of the things true colors ( Its colour and lustre) With a standard light shows the relationship between the light source. Ra is sure method is to DIN6169 standards defined in the eight kinds of tested test color in standard light source and light, the smaller color indicates by metering source color the better color rendering. The Ra value is 100 light source said things in the light and the colors displayed under the standard light source. Characteristics of OLED homogeneity 85% or greater of OLED products work on the intensity of illumination uniformity is the important index of comfortable visual task lighting, eyes staring, staring eyes, concentrate for a long time is not comfortable factor area can cause eye obvious fatigue or damage imperceptible.
