Fluorescent energy-saving lamp life prolonging starting module and fluorescent energy-saving lamp

Abstract

The invention provides a fluorescent energy-saving lamp which comprises a time delay circuit, a switching circuit, a preheating capacitor and an electronic ballast. The fluorescent energy-saving lamp has the advantages that a fluorescent energy-saving lamp life prolonging starting module is the same as a current-limiting time delay switch, by the utilization of the fluorescent energy-saving lamp life prolonging starting module, at the moment when the electronic ballast is connected with a power supply and started, the switch is connected to enable the capacity of a starting capacitor to be increased, so that LC resonance of the ballast is detuned, and high-voltage glow starting cannot be generated; meanwhile, the module controls the current of a filament, so that the filament is in a preheating state, after preheating is finished, the LC resonance of the electronic ballast returns to normal, and high-voltage glow starting is generated. Through effective control over filament preheating, electronic powder bombardment isolation of the filament is greatly restrained; turn-on and turn-off life of the fluorescent energy-saving lamp is prolonged from less than 10000 times to not less than 30000 times, and therefore the fluorescent energy-saving lamp can totally meet the requirements of some illumination places where lamps need to be turned on and turned off frequently, for example, a light source for intelligent illumination control in a corridor needs to be used for more than two years.

Description

technical field [0001] The invention relates to the lighting field, in particular to a fluorescent energy-saving lamp life-extending starting module and a fluorescent energy-saving lamp. Background technique [0002] In the field of fluorescent energy-saving lamps, there has always been a technical bottleneck that the "electronic powder" coated on the surface of the filament is blasted away when the lamp glow is started, so the life of fluorescent energy-saving lamps is limited by the number of switches, generally only 5000-10000 times The switching life of the fluorescent energy-saving lamps sold on the market can only be less than 10,000 times. Contents of the invention [0003] In order to solve the problems in the prior art, the invention provides a fluorescent energy-saving lamp. [0004] The invention provides a fluorescent energy-saving lamp, which includes a delay circuit and a switch circuit, and the delay circuit and the switch circuit are connected in parallel ...
