Ten, several common source
Preheat type electronic energy-saving lamps
Preheat multi-lamp electronic energy saving lamps, low-voltage lighting belongs to a new patented product. It includes a push-pull oscillation circuit and a relay delay circuit, wherein: the low-pressure side of the transformer winding and the preheating circuit is connected to a push-pull oscillation circuit. Compared with the prior art, capable of efficiently preheating the filaments, greatly extend the service life, low voltage control preheating the fluorescent lamp, easy to cause breakdown of the relay contacts, and filament preheating current can be promptly disconnected, saving energy. This kind of anti-voltage fluctuation lamp good performance; stable power output, the use of preheat start-up mode, the effective protection of the filament; using in-line terminals, installation more convenient; high power factor; L-class standards, the total harmonic content, divided low harmonic content; 3C meet the latest safety and performance standards; compliance with various domestic and international safety and performance standards, slim and compact profile make the luminous flux evenly distributed in the larger space; life of up to 10,000 hours, reducing lamp maintenance costs; GE Patent appearance design, lamp located in central tube, does not form a shadow, it is an ideal choice for the current solar energy source. ?

? high pressure sodium lamp is a high intensity discharge lamps, belongs to the third generation of electric light, through the electric arc tube, resulting in electric arc electric arc between the two ends of the tube electrodes, electrically isolated high temperature, so that sodium mercury tube heat evaporation Qi into frequent collision mercury vapor and sodium vapor, sodium atom electron emission cathode between to give a yellow light spectrum of the light source, with high luminous efficiency, long life, through the fog, and other characteristics, suitable for roads, airports, docks, squares, stadiums, exhibition halls, industrial and mining enterprises and other places lighting. ? low pressure sodium
Low pressure sodium lamp is a low-pressure sodium vapor discharge, internal piping with special anti-soda glass blown, point and can radiate 5890A, 5896A sodium lines, lighting can also be used as polarimeter, refractometer, polarimeter other optical instruments monochromatic light source. Few now widely used.
