Ultralow temperature energy-saving lamp

Abstract

The invention relates to an electronic energy-saving lamp belonging to the technical field of energy-saving lamps, in particular to an energy-saving lamp which can be normally started in an ultralow temperature environment. The electronic energy-saving lamp is characterized by adopting an electronic starter instead of an original inducting type ballast and a starter on a fluorescent lamp tube, the one-step rapid start can be realized, and the service life of the lamp tube is prolonged; the energy-saving lamp has wide application range of voltage and can be normally started in a low temperature and even ultralow temperature environment; and compared with a common incandescent lamp, the power factor is greatly improved, and the electric energy is saved.

Description

technical field [0001] The invention relates to an ultra-low temperature energy-saving lamp, which can be applied to various occasions under low temperature or even ultra-low temperature environments, and belongs to the technical field of energy-saving lamps. Background technique [0002] Energy-saving fluorescent lamps sold in the existing market are usually ignited by induction ballasts and starters. Its disadvantage is that due to the harsh working temperature of the ballast and starter itself, it cannot work in a low temperature or even ultra-low temperature environment (for example, below -30°C), which makes the fluorescent lamp unable to start and ignite, making this type of energy-saving lamp The application in cold regions is greatly limited; at the same time, because the ignition process often needs to go through many jumps to achieve stable light emission, this jump process will also greatly damage the service life of the lamp tube. [0003] The invention applicat...

[0003] The invention application with application number 200820048853.2 discloses an energy-saving lamp that can be started in a low-temperature environment. It uses an electrodeless light source and a low-temperature start-up circuit board to realize the low-temperature start-up of the electrodeless lamp, but the structure of the low-temperature start-up circuit board is complicated and does not Applicable to energy-saving lamps other than electrodeless lamps; the invention application with application number 97246253.8 discloses a long-life energy-saving lamp, which uses a push-pull oscillating circuit to ensure stable operation of the energy-saving lamp and prolong its service life, but its low-temperature start-up performance has not been significantly improved improve
