Abstract

The invention relates to a protection and control circuit for the electronic ballast of a high power HID lamp. A lamp stat detector detects the working state of an HID lamp. The lamp state detector is provided with two paths of output. One path of output is connected with an automatic power controller and inputs a lamp state signal to the automatic power controller. The input of the automatic power controller is connected with the input terminal of a drive controller, and the automatic power controller sends a power adjustment signal to the drive controller according to the lamp state. The other path of the output of the lamp state detector is connected with the wiring node of a failure protector and a restart controller and transfers the lamp state signal. The restart controller is connected with the input terminal of the drive controller by the failure protector and provides the lamp state signal and a restart control signal to the drive controller. The input terminal of the drive controller is also connected with a temperature compensating circuit and provides a temperature adjustment signal to the drive controller. The drive controller outputs a power drive control signal. The protection and control circuit ensures that the electronic ballast of the high power HID lamp can be used.

Description

technical field [0001] The invention relates to a ballast working circuit, in particular to a high-power HID lamp electronic ballast protection and control circuit. Background technique [0002] HID lamps mainly include high pressure sodium lamps, metal halide lamps and mercury lamps. There are already stereotyped electronic ballasts used in low-power gas discharge lamps below 75W such as fluorescent lamps and energy-saving lamps. There are also various stereotyped products for the drive control circuit in electronic ballasts, such as the KA754X series of Fairchild. Chips, IR Company's IR215X series chips, MicroLinear Company's ML483X series chips, Motorola Company's MC33157 chips, and so on. However, existing electronic ballasts cannot be directly applied to high-power HID lamps of 75-1000W. The main reasons are that the electronic ballast will be burnt out soon after the high-power HID lamp is not lit after power-on or self-extinguishing or broken lamp occurs; the other ...
