流光溢彩指的是电视周围有几种颜色的LED，可以根据播放内容的边缘颜色来搭配相近的颜色让用户感觉到一种附加效果，增加身临其境的感觉。

黯然失色：黯然：心里不舒服、情绪低落的样子；失色：因惊恐而变以脸色。本指心怀不好，脸色难看。后多比喻相形之下很有差距，远远不如。

Ambilight, short for "ambient lighting", is a lighting system for televisions developed by Philips.

Ambilight是周围照明的简称，是飞利浦开发的一种电视照明系统。

Ambilight creates light effects around the television that correspond to the video content.

Ambilight对应视频内容在电视周围创造照明效果。

Philips claims that a "more immersive viewing experience" can result.

飞利浦声称它能产生一个“更加身临其境的视觉体验”。

Ambilight is a lighting system that actively adjusts both brightness and color based upon picture content.

Ambilight是一个照明系统,它能基于图片内容积极地调整亮度和颜色。

Integrated into the television cabinet, Ambilight technology is aimed to enable the viewer to see more picture detail, contrast and color while eliminating on-screen reflections.

集成到电视柜上的Ambilight技术，目的是使观众看到更多的图片细节,对比和颜色从而消除屏幕上的反射。

Ambilight technology works by projecting light from the rear of the TV cabinet in a very wide range of colors, shades and intensities.

Viewers can choose to have Ambilight follow the color and brightness of the programme content – automatically changing with the colors on the screen – or alternatively the light levels and color can be set to match the interior decor or mood in the room. When the television is not on, the unit becomes a lamp, capable of displaying dynamic light patterns. Adults and children may be staring at screens for extended periods of time, both at home and on the road. When they focus on one thing for too long, the accommodating eye muscles get stressed and tired, thereby causing visual fatigue. Philips Ambilight TV with the back light feature aims to help ease eye fatigue and strain.

Ambilight is a feature invented in 2002 by the Philips ASA lab (a central development lab of Philips Consumer Electronics, also responsible for development of flat TV) and Philips Research, both situated in Eindhoven, the Netherlands. These departments worked in parallel: They started from different starting-points, and ended at comparable technologies. Philips Research investigated the application of LED in the home environment. This development resulted in a lighting system that displayed light according to a program (script) that has to be generated for all displayed video content, and which should be translated to the used lamp configuration. Movie directors could use a script to add special effects. The system was demonstrated using multiple light units, spread over the room. The starting point of the ASA lab was the wish to add (white) light units to the cabinet of the flat TV. These light units, lighting the wall around the TV, had to replace the table lamp often placed on top of the bulky CRT TVs. This development resulted in a TV lighting system (based on RGB LED) that reproduces the color and brightness of the content displayed on the TV screen. The concept does not require light-scripts, and is backwards compatible with existing video content. Introduction of this concept was less complicated because it only affects the TV itself. This concept was selected for the Philips Ambilight TVs that have been launched since 2004.

Versions

Although Ambilight was developed using LED light sources, the first Ambilight TVs (launched in 2004) were equipped with CCFL tubes. The higher brightness of the CCFL tubes was preferred to make the Ambilight more visible in bright shop environments, at the cost of a reduced color gamut. Red, green and blue CCFL tubes were mounted at the backside of the cabinet (at the left and right side), reproducing the average screen color. In later executions of Ambilight, the CCFL tubes were replaced by LEDs (2006), resulting in an Ambilight color gamut that matches the picture color gamut. The visual effect was further improved by adding Ambilight at the top and (for wall-hanging applications) bottom side of the screen. By splitting the Ambilight area in segments of which the color could be individually adapted to the neighboring screen area, the effect of extrapolating the screen on the wall was further improved. To reduce the dark boundary between display and Ambilight area, the “Aurea” TVs were introduced (2007), in which also the bezel of the screen was lighted by the Ambilight system.

With each new generation of Ambilight products, the size of the Ambilight system has been reduced to match with the constant reducing thickness and bezel width of flat TVs. The algorithm (the program that translates the displayed picture towards the Ambilight colors) is constantly improved to optimize the effect for all situations. In the latest executions it is possible to correct the Ambilight for non-white (tinted) walls behind the TV.

AmBX is a version of Ambilight designed for PC gaming. Similarly, light effects occur resulting from in-game events and actions.

Patents

The concept of adapting ambient light with a video display already existed, but proposed solutions required a separate channel for the light effects in addition to the video and audio channels. Ambilight uses the video channel itself to generate color and the concepts as well as various methods of calculating the color from the video signal are protected by various patents.

The basic Philips Ambilight patent is EP 1379082, written by Theo Overes of the ASA lab. Other inventors are Aeneas Fletterman (graduate student at ASA lab), and the Philips research team led by Elmo Diederiks, consisting of a diverse mix of experts in psychology, user research, software engineering and theatre lighting. Since this basic patent, Philips filed many other patent applications, covering hard and software of the system.
