Description

Ballast with antidetonation heat dissipation shell

Technical Field

The utility model relates to a ballast with antidetonation heat dissipation shell belongs to ballast installation technical field.

Background

The ballast (ballast resistor) is usually a device which plays a role in current limiting and generating instantaneous high voltage on the fluorescent lamp, and is made by winding enameled wires on an iron core made of silicon steel, and when the coil with the iron core is powered on/off instantaneously, the coil can generate high voltage by self-induction and is added on electrodes (lamp filaments) at two ends of the fluorescent lamp tube. This action is performed alternately, when the starter (jump bulb) is closed, the filament of the lamp tube is conducted to generate heat through the current-limiting of the ballast; when the starter is opened, the ballast will generate high voltage by self-induction and apply it to the filaments at two ends of the lamp tube, the filaments emit electrons to bombard the fluorescent powder on the tube wall to give out light, and the starter is turned on and off several times, and the lamp tube is turned on. When the lamp tube is normally lighted, the internal resistance is reduced, and the starter is always kept in an open circuit state, so that the current stably passes through the lamp tube and the ballast to work, and the lamp tube is normally lighted. When the ballast works, current always passes through the ballast, so the ballast is easy to vibrate and generate heat, and the ballast can generate loud sound and is easy to burn out when the quality of the ballast is poor, particularly when the quality of the ballast is poor.

Particularly in the field of high-power lamps such as high-voltage sodium lamps and metal halide lamps, in order to eliminate vibration generated by a traditional ballast during working, the vibration can be reduced to the maximum extent by additionally arranging a cushion pad, but the cushion pad is usually made of plastic or rubber, has very low heat conductivity coefficient, is not beneficial to heat dissipation of the ballast, is in a high-temperature environment for a long time, is easy to age, is usually replaced every 1 to 3 years, and has huge frequent maintenance cost in occasions with high maintenance cost, such as mines and mines, due to environmental limitation; even in some working environments with severe environments, if the ballast has poor heat dissipation, the ballast has potential safety hazards.
