White LED light is considered to be the light source of this century, which is environmentally friendly, efficient, power saving, and has a long life. In addition, its  

Interior lighting fixtures have gradually become popular, and are equipped with intelligent control technology with adjustable illuminance and color temperature.

Most of the LED white light is excited by the blue light crystal grains to excite the yellow light phosphor to produce a white light spectrum. This blue light wave range is close to the blue light hazard defined by photobiological safety (IEC62471), which may easily cause consumers to doubt whether the LED will have blue light hazard. The measurement standard of photobiological safety to blue light hazard, after actual comparison, commercially available LED lighting products, general LED bulbs, LED lamps, LED lamps, etc., do not have blue light hazard doubts.

Inappropriate blue light wavelengths can cause blue light hazards, but depending on the visual response to light, blue light wavelengths can increase dopamine secretion during the day, which has a positive impact on physiological arousal, positive emotions and endocrine. Therefore, a high proportion of blue light or light with high color temperature is required during the day, but at night, considering that the blue light band will interfere with the secretion of melatonin, it is suitable to use low color temperature lighting at night. LED lighting with adjustable high and low color temperature can gradually become a new choice for healthy lighting according to the different needs of lighting during the day and night.

As far as the application side is concerned, the basic difference between OLED and LED is that OLED light source is brighter in color and can be easily made into various flat or curved surfaces, while LED light source has absolute advantages in terms of service life, high lumens and cost. As for organic/inorganic compounds, it should not cause much impact. Both of them also do not contain heavy metal elements such as lead and mercury that pollute the environment.

White light OLED is a new generation of artificial light source, the light source is organic compounds, and does not contain harmful substances such as lead and mercury; the characteristics of lighting are flat light, uniform surface light source, low color temperature, flexible, extremely thin, transparent, and nine It is easy to combine with various building materials, and the light is soft and comfortable, very close to the sunlight of nature, so it is suitable for applications that cut into interior design, human-induced lighting or health appeals.

But the disadvantage is that it has a shorter lifespan. In terms of luminous efficiency, OLEDs have recently made significant improvements, not far from the level of LEDs. However, due to the lower total power, although the luminous efficiency is improved, the total luminous amount still needs to be enhanced to meet the needs of general lighting. Strictly speaking, OLED is also a kind of LED. If there are issues such as blue light and health, it will be of the same degree, and there will not be much difference.

With the evolution and demand of the market, lighting is no longer just a light source, but an important element in creating a living atmosphere. OLED lighting is regarded as the next-generation lighting technology, known as the next-generation solid-state lighting technology, with ultra-thin, sunlight-like characteristics, flat light source, soft and comfortable light, rich colors, and lighting design will have unlimited creative space It can be used so that users will be able to use a whole new way to decorate the surrounding environment with "light".
