Phase-out Of Incandescent Light Bulbs
Various governments have passed regulations to phase out manufacturing or importation of incandescent light bulbs for general lighting in favor of more energy- efficient alternatives. The regulations are generally based on efficiency, rather than use of incandescent technology. However, it is not unlawful to continue to buy or sell existing bulbs, which are unregulated. Brazil and Venezuela started the phase-out in 2005, and the European Union, Switzerland, and Australia began to phase them out in 2009. Likewise, other nations are implementing new energy standards or have scheduled phase-outs: Argentina, and Russia in 2012, and Canada,"Canada to ban incandescent light bulbs by 2012" |
Yonhap
Yonhap News Agency is a major South Korean news agency. It is based in Seoul, South Korea. Yonhap provides news articles, pictures and other information to newspapers, TV networks and other media in South Korea. History Yonhap (, , translit. ''Yeonhap''; meaning "united" in Korean) was established on 19 December 1980, through the merger of Hapdong News Agency and Orient Press. The Hapdong News Agency itself emerged in late 1945 out of the short-lived Kukje News, which had operated for two months out of the office of the Domei, the former Japanese news agency that had functioned in Korea during the Japanese colonial era. In 1999 Yonhap took over the Naewoe News Agency. Naewoe was a South Korea government-affiliated organization, created in the mid 1970s, and tasked with publishing information and analysis on North Korea from a South Korean perspective through books and journals. Naewoe was known to have close links with South Korea's intelligence agency, and according to the B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colorfulness
Colorfulness, chroma and saturation are attributes of perceived color relating to chromatic intensity. As defined formally by the International Commission on Illumination (CIE) they respectively describe three different aspects of chromatic intensity, but the terms are often used loosely and interchangeably in contexts where these aspects are not clearly distinguished. The precise meanings of the terms vary by what other functions they are dependent on. * Colorfulness is the "attribute of a visual perception according to which the perceived color of an area appears to be more or less chromatic"., page 87. The colorfulness evoked by an object depends not only on its spectral reflectance but also on the strength of the illumination, and increases with the latter unless the brightness is very high ( Hunt effect). * Chroma is the "colorfulness of an area judged as a proportion of the brightness of a similarly illuminated area that appears white or highly transmitting". As a resu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CBS Los Angeles
KCBS-TV (channel 2) is a television station in Los Angeles, Los Angeles, California, United States, serving as the West Coast of the United States, West Coast flagship (broadcasting), flagship of the CBS network. It is owned-and-operated station, owned and operated by the network's CBS News and Stations division alongside Independent station (North America), independent outlet KCAL-TV (channel 9). Both stations share studios at the CBS Studio Center on Radford Avenue in the Studio City, Los Angeles, Studio City section of Los Angeles, while KCBS-TV's KCBS-TV/FM Tower, transmitter is located on the western side of Mount Wilson (California), Mount Wilson near Occidental Peak. Aside from being affiliated with CBS News, since 2017, KCBS-TV has had no connection to KCBS (AM), KCBS radio (740 AM) in San Francisco.

LED Lamps
An LED lamp or LED light bulb is an electric light that produces light using light-emitting diodes (LEDs). LED lamps are significantly more energy-efficient than equivalent incandescent lamps and can be significantly more efficient than most fluorescent lamps. The most efficient commercially available LED lamps have efficiencies of 200 lumen per watt (Lm/W). Commercial LED lamps have a lifespan many times longer than incandescent lamps. LED lamps require an electronic LED driver circuit to operate from mains power lines, and losses from this circuit means that the efficiency of the lamp is lower than the efficiency of the LED chips it uses. The driver circuit may require special features to be compatible with lamp dimmers intended for use on incandescent lamps. Generally the current waveform contains some amount of distortion, depending on the luminaires’ technology. The LED lamp market is projected to grow from US$75.8 billion in 2020 and increasing to US$160 billion in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Public Radio
National Public Radio (NPR, stylized in all lowercase) is an American privately and state funded nonprofit media organization headquartered in Washington, D.C., with its NPR West headquarters in Culver City, California. It differs from other non-profit membership media organizations such as the Associated Press, in that it was established by an act of Congress. Most of its member stations are owned by non-profit organizations, including public school districts, colleges, and universities. It serves as a national Radio syndication, syndicator to a network of over 1,000 public radio List of NPR stations, stations in the United States. , NPR employed 840 people. NPR produces and distributes news and cultural programming. The organization's flagship shows are two drive time, drive-time news broadcasts: ''Morning Edition'' and the afternoon ''All Things Considered'', both carried by most NPR member stations, and among the List of most-listened-to radio programs, most popular radio p ...
