Abstract
The utility model discloses a safety energy-saving lamp for machine tools, which belongs to the application of electronic technology in lighting control. The utility model comprises a power transformer and a lighting lamp and is characterized in that a pulse transformer and a projecting lamp with low power consumption are used to replace a mains power transformer and a filament lamp with high power consumption. The on-off of a fire wire is controlled by an earth wire electrification detecting device to achieve the purpose of safety and electricity saving. The utility model has the circuit structure that a capacitor is charged by mains through a resistor after bridge rectification, a bidirectional trigger diode is switched on and two transistors connected with the bidirectional trigger diode are alternately switched on and off through the coupling of an oscillating transformer to form an oscillation. A high frequency pulse can light a halogen-tungsten projecting lamp through the voltage generated in a secondary level by the pulse transformer. The utility model uses the earth wire electrification detecting device bridged on a zero earth wire to control the fire wire to switch on and off through a switching tube. The electricity can be saved by 60 percent by lighting the halogen-tungsten projecting lamp using a high frequency current than using the power transformer to light the filament lamp in a voltage-reducing mode. The utility model has the earth wire for electrification protection.
