Examples for Haitz's law—which predicts an exponential rise in light output and efficacy of LEDs over time—are the CREE XP-G series LED, which achieved 105 lm/W in 2009 [52] and the Nichia 19 series with a typical efficacy of 140 lm/W, released in 2010.
On-set virtual production (OSVP) [a] is an entertainment technology for television and film production in which LED panels are used as a backdrop for a set, on which video or computer-generated imagery can be displayed in real-time.
Cree's XLamp XM-L LEDs, commercially available in 2011, produce 100 lm/W at their full power of 10 W, and up to 160 lm/W at around 2 W input power. In 2012, Cree announced a white LED giving 254 lm/W, [10] and 303 lm/W in March 2014. [11] Practical general lighting needs high-power LEDs, of one watt or more.
LED film, also called LED-embedded light film [1] is a new technology of surface-mount light-emitting diodes (LEDs) on flexible transparent conductive polymer films. This technology is based on the use of a cold curing pick-and-place process on transparent conductive plastics. [2] [3]
It's sometimes hard to keep track of positions in an IndyCar race, especially if you're in the stands and don't have the luxury of a broadcaster or data stream to point things out. Never fear ...
The PhlatLight LEDs are also used in a new class of ultra-compact DLP front projector commonly referred to as a "pocket projector" and have been introduced in new models from LG Electronics (HS101), Samsung (SP-P400) and Casio (XJ-A series). Home Theater projectors will be the next category of DLP projectors that will use PhlatLight LED technology.

LED display of a TI-30 scientific calculator (c. 1978), which uses plastic lenses to increase the visible digit size X-Ray of a 1970s 8-digit LED calculator display. Until 1968, visible and infrared LEDs were extremely costly, on the order of US$200 per unit, and so had little practical use. [23]
