Problems solved by technology

[0005] 1. Combining two general single lamp ballasts of 35W into a double lamp electronic ballast, the single bulb supplies 35W, and the double bulbs have a total of 70W, causing the temperature of the lamp to be too high, which is easy to burn the lamp, and consumes a lot of current.
[0006] 2. Combining two 24W general single-lamp ballasts into a dual-lamp electronic ballast, a single lamp supplies 24W and double bulbs a total of 48W, resulting in insufficient brightness when the single bulb is used, and the wattage is too small to easily cause the lamp to turn off and turn on Disadvantages such as instability (flickering)

Abstract

The related control system for an electronic stabilizer of high-voltage gas discharge lamp comprises: a power circuit, a selection unit, two transformers, a sensor unit, a process unit, and a signal modulation unit. This invention reduces lamp temperature, and improves lamp efficiency.

Description

technical field [0001] The invention relates to a control system of an electronic ballast, in particular to a control system of an electronic ballast of a high-pressure gas discharge lamp. Background technique [0002] With the development of lighting technology, all lighting equipment is devoted to the research of high efficiency and power saving. Among them, a high-pressure gas discharge lamp has gradually been favored by users in recent years. The beam of high-pressure gas discharge lamp is stronger, and the wattage can be reduced relatively, so it has the advantage of high efficiency. In terms of service life, the high-pressure gas discharge lamp also has a longer service life, which can relatively reduce maintenance times and reduce costs. [0003] Currently, the electronic ballasts with double tubes commonly used in the market, because of their poor control design, most of them have disadvantages such as low efficiency, high lamp temperature and high power consumption...
