Semiconductor lighting technology is developing rapidly. While seeking high luminous efficiency, low cost, and superior reliability, researchers are increasingly focusing on the effects of LED ...
MUNICH--(BUSINESS WIRE)--Seoul Semiconductor Co., Ltd. (KOSDAQ 046890), a leading global innovator of LED products and technology, announced that its SunLike Series natural spectrum LEDs have been ...
This relatively simple circuit uses a 6-V DC supply with a PWM current-source configuration to provide efficient, adjustable dimming of a white LED over a wide range, needed to accommodate the unique ...
SunLike is a series of leds from Seoul Semiconductor, intended to producing light that closely matches the spectrum of natural sunlight (but check spectrum below too). Key to the led is the use of a ...
Consortium test this week will investigate how unused TV spectrum could be tapped for new wireless broadband networks, according a Financial Times report. Steven Musil is the night news editor at CNET ...
These four examples show (a) the best fit (blue solid line) to daylight D65, (b) an incandescent spectrum, (c) the melanopic, and (d) a white LED spectrum (Ph-LED YAG) (dashed black lines) made by ...
A typical LCD consists of liquid crystal material with transparent electrodes and polarizing filters. Applying voltage across the liquid crystal layer allows light to pass through in varying amounts.
