LED power dissipation is modeled as a current source; thermal resistance is modeled as a resistor; and the ambient temperature is modeled as a voltage source. High power light-emitting diodes (LEDs) can use 350 milliwatts or more in a single LED. Most of the electricity in an LED becomes heat rather than light – about 70% heat and 30% light. [1]
The luminous trims combine the diffused quality of lensed trim but with an open downlight component. Adjustable trim allows for the adjustment of the light whether it is eyeball style, which protrudes from the trim or gimbal ring style, which adjusts inside the recess. These lights allow for full versatility. [4]
An LED strip, tape, or ribbon light is a flexible circuit board populated by surface-mount light-emitting diodes (SMD LEDs) and other components that usually comes with an adhesive backing. Traditionally, strip lights had been used solely in accent lighting, backlighting, task lighting, and decorative lighting applications, such as cove lighting .
Simple LED (Light Emitting Diode) circuit diagram. In electronics, an LED circuit or LED driver is an electrical circuit used to power a light-emitting diode (LED). The circuit must provide sufficient current to light the LED at the required brightness, but must limit the current to prevent damaging the LED.
Gerard Philips (1858–1942), founder. The Philips Company was founded in 1891, by Dutch entrepreneur Gerard Philips and his father Frederik Philips. Frederik, a banker based in Zaltbommel, financed the purchase and setup of an empty factory building in Eindhoven, where the company started the production of carbon-filament lamps and other electro-technical products in 1892.
Original 120, 620 and modern 120 film spools with modern 120 exposed color film. 120 is a film format for still photography introduced by Kodak for their Brownie No. 2 in 1901. . It was originally intended for amateur photography but was later superseded in this role by 135 film. 120 film survives to this day as the only medium format film that is readily available to both professionals and ...
This first involved a 140-millimeter (5.5 in) tank gun named Neue Panzerkanone 140 ('new tank gun 140'), but later turned into a compromise which led to the development of an advanced 120 mm gun, the L/55, based on the same internal geometry as the L/44 and installed in the same breech and mount. The L/55 is 1.32 metres (4.3 ft) longer ...
The M1943 Mortar or 120-PM-43 (Russian: 120-Полковой Миномёт-43) or the 120-mm mortar Model 1943 (Russian: 120-мм миномет обр. 1943 г.), also known as the SAMOVAR, is a Soviet 120 millimeter calibre smoothbore mortar first introduced in 1943 as a modified version of the M1938 mortar. [5]
