The appearance of objects illuminated by that light may vary as the spectrum varies. This is the issue of color rendition, quite separate from color temperature. An orange or cyan object could appear with the wrong color and much darker as the LED or phosphor does not emit the wavelength it reflects.
A 230-volt LED filament lamp, with an E27 base. The filaments are visible as the eight yellow vertical lines. An assortment of LED lamps commercially available in 2010: floodlight fixtures (left), reading light (center), household lamps (center right and bottom), and low-power accent light (right) applications An 80W Chips on board (COB) LED module from an industrial light luminaire, thermally ...
A LED is a long-lived light source, but certain mechanisms can cause slow loss of efficiency of the device or sudden failure. The wavelength of the light emitted is a function of the band gap of the semiconductor material used; materials such as gallium arsenide , and others , with various trace doping elements , are used to produce different ...
We break down the differences between the three main types of TV screen tech – and bring you some of the best models from each category.
LED TVs, in contrast to older LCDs, have LED backlighting, leading to modest improvements in the picture quality. A few years ago, this was a serious debate -- was it worth it to pay more for an ...
Because the LED casts light in only one direction, the most common way LED lights are designed, even "plain" sets having some sort of crystal pattern to create refraction. Many bargain brands have dome-shaped LEDs which focus the light so that it's sharply visible when viewed head-on, but almost invisible from a perpendicular direction.
