相比之下，OLED 发光面板本质上是均匀且无眩光的，因此 OLED 发光面板的能效与提供的光效率相匹配。这种影响非常显著，以至于在某些应用中，OLED 照明解决方案比 LED 照明解决方案更均匀、更节能。
LEDs are tiny, highly concentrated light sources thatare suited for producing intense beams of light required in car headlights,headlamps, torches and other high-intensity, focused lighting applications. Tomake LEDs useful for automotive interior lighting or other low-intensityapplications, the LED light must be diffused, scattered and homogenized, whichreduces the energy efficiency of the light ultimately delivered.
In contrast, OLED light panels are inherentlyhomogeneous and glare-free, so the energy efficiency of OLED light panelsmatches the light efficiency delivered. This effect is so significant that insome applications, the OLED lighting solution is both more homogeneous and moreenergy efficient than the LED lighting solution.
OLED Lighting vs OLED Display
OLED 的光品质满足以下两种应用。在照明方面，自然漫射光束将 OLED 灯具定位为无眩光的全彩体验，以实现视觉舒适。对于显示领域，直接全彩输出可实现包括真黑在内的高色域。
Both the OLED display and OLED lighting are based on the same principles of solid-state physics. OLED technology consists of organic semiconductor materials that emit light when electrically energized. The OLED materials emit all wavelengths directly and do not require phosphor conversion to achieve the desired spectrum.
OLED luminaires are optimized for illumination, unlike OLED displays, so OLED luminaires are much brighter than OLED displays (8,000 nits for OLED luminaires compared to less than 1,000 nits for OLED displays). OLED luminaires also have a much longer lifetime than OLED displays. OLED lighting drops to 70% of initial brightness at over 100,000 hours of continuous use compared to OLED displays, which drop from a much lower initial brightness to 50% over the same period.
Exposure to high-intensity blue wavelengths is associated with macular degeneration and circadian rhythm disturbances, depending on the exposure time. Light sources such as fluorescent lamps, which are bright white and cool, and incandescent bulbs have a higher risk for damaging to your eyes.

OLEDs are inherently safe because they deliver all wavelengths of light, including blue light. OLEDs deliver the light levels you need at an intensity far below the risk of damage. This is validated by the IEC standard for the physiological risk of blue and infrared light - OLEDs pose no risk to skin or eyes and are considered free of all photobiological risks.
宽光谱 OLED 灯提供全色调色板，同时消除大多数人工照明解决方案的负面特性，如紫外线、眩光、阴影和闪烁。将 OLED 的亮度与其独有的柔软度相结合，可以改善环境并提供类似日光的光线，即使您整天坐在室内，一直如白天般感觉。
Wide-spectrum OLED light provides a full color palette while eliminating the negative characteristics of most artificial lighting solutions such as UV, glare, shadow and flicker. OLED's combination of brightness and inimitable softness enhances the environment and provides with daylight-like light - even if you sit indoors all day.
世界上将近20% 的电力用于照明。照明能源占全球温室气体的 6%，大约为 19 亿吨二氧化碳，约占全球所有乘用车排放量的70%（来源：联合国环境规划署）。通过使用节能照明——例如 OLED 照明——这些数值可以被显着降低。测试表明，OLED 照明效率正变得与 LED 一样高效，节能率高达 80% 。这说明与传统白炽灯泡相比，OLED照明的节能效果更加显著。此外，这种OLED光源的制造过程非常高效。
Almost 20 percent of the world's electricity is used for lighting. Energy for lighting accounts for six percent of global greenhouse gases. That is about 1.9 billion tons of CO2 or about 70 percent of the emissions of all passenger cars worldwide (source: United Nations Environment Program). By using energy-saving lighting - such as OLED lighting - these values can be significantly reduced. Tests have shown that OLED lighting becomes about as efficient as LEDs already are. These provide up to 80 percent better efficiency, illustrating the energy savings with OLED lighting compared to traditional incandescent bulbs. In addition, the manufacturing process of this light source is very efficient.
OLED 灯具是面光源，无需漫射光的漫射屏。这有一个主要优势，因为使用传统光源时，系统会损失多达 70% 的光输出。采用OLED照明技术，光源的效率等于系统效率。此外，OLED 照明灯几乎 100% 由玻璃制成，可以在损坏后轻松回收。
OLED luminaires are surfacelight sources that eliminate the need for a diffuser screen that diffuses thelight. This has a major advantage, because with conventional light sources up to70 percent of the light output is lost through the system. With OLED lighting technology,the efficiency of the light source is equal to the system efficiency.Additionally, OLED lighting is almost 100 percent glass, that can be easilyrecycled at the end of its life.
Some disadvantages of OLEDs
OLED 的使用寿命取决于温度：低初始光度但散热良好的 OLED（任何颜色）比从一开始就以最大光度运行而无散热的OLED 具有更长寿命，这是因为在较高温度下OLED材料的扩散发生得更快。
OLED 的另一个缺点是，与LED相比，市售 OLED 的发光效率仅为 40 lm/W - 60 lm/W范围内。OLED的实验室测试光效最高仅能达到略高于 100 lm/W ，而发光二极管的实验室测试值可达200 lm/W。
The service life of OLEDs is temperature-dependent: A well-cooled OLED (of any color) with a low initial luminosity always has a longer life than an OLED that is operated at maximum luminosity from the start without cooling. This is due to diffusion processes in the OLED that occur more quickly at higher temperatures.
Another disadvantage of OLEDs is the lower luminous efficacy in the range of 40 lm/W to 60 lm/W of commercially available OLEDs compared to light-emitting diodes. Peak values of selected laboratory samples of OLEDs achieve values just above 100 lm/W. Light-emitting diodes achieve laboratory values of 200 lm/W.
In addition to shorter life and lower luminous efficacy, OLEDs also react sensitively to certain external substances. In addition to water, which is omnipresent due to humidity, penetrating oxygen can also destroy the organic material. It is therefore important to hermetically encapsulate the display and protect it from external influences. The necessary rigid encapsulation impairs flexibility. The highly reactive injection layer of calcium and barium is especially endangered by corrosion with oxygen. Typical signs of failure are circular, growing non-luminous areas, so-called "dark spots". The cause is often particle contamination during vapor deposition of the metal layers. The microscopic edges of the multilayer structure are also infiltrated by corrosion, which leads to a decrease in the effective luminous pixel area in screen applications.
