Problems solved by technology

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, this jump process will also greatly damage the service life of the lamp

Embodiment Construction

[0018] Attached below figure 1 Illustrate the working principle of the present invention: the electronic starter circuit 1 is composed of four diodes D 1 ~D 4 and two diodes C 1 、C 2 Composed of voltage doubler rectifier circuit, C 3 Used to control the working current of the lamp tube. When an AC power source (preferred voltage is 220V) is connected, the voltage doubler rectifier circuit converts the AC power into a DC power to generate a higher potential, so that two poles 3 and 4 A high potential difference is generated between them, forming an arc discharge. Connect a selected resistor R in series between the lamp tube 2 and the electronic starter circuit 1 1 , whose purpose is to change the negative characteristics of the voltage and current characteristics of the lamp discharge circuit into positive characteristics. When the lamp tube is lit, the discharge can reach a stable condition. Resistance R 2 Is the discharge resistor, used to discharge the capacitor C a...

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...
