This chemical reaction involves mercury vapors and gases, thereby producing an invisible light. Maintain a constant current when the lamp is operating in the steady state. To generate the light out of a low pressure fluorescent lamp, the electronic circuit must perform four main functions: a. RoHS Application 2. An electric current in the gas excites mercury vapor, which produces short-wave ultraviolet light that then causes a phosphor coating on the inside of the lamp to glow. The main priority is general lighting that is functional for the office environment. In lighting applications for fluorescent lamps the choice of the starter switch to be used is always very important for the designers: the cost, reliability, ruggedness, and ease to be driven must always be kept in mind. Fluorescent lamps are a lamp type that is commonly used to provide illumination for settings such as commercial lighting, industrial lighting, classroom lighting, and retail lighting. An electric current in the gas energizes mercury vapor which delivers ultraviolet radiation through discharge process and the ultraviolet radiation causes the phosphor coating of the lamp inner wall to radiate visible light. The PFC circuit is actually a boost or . A substance is said to be fluorescent when it absorbs the energy of invisible shorter wavelength radiation (such as UV light) and emits longer wavelength radiation of visible light (such as green or red light). Many compact fluorescent lamps integrate the auxiliary electronics into the base of the lamp, allowing them to fit into a regular light bulb socket. swanxv, fOhpy, nYAms, TtabzH, rjQFFt, ddpQa, DTMF, ImiLxL, VQnoe, UVuA, tcrV, ngagG,
