Double-light source switching illuminating lamp and working method thereof

Abstract

The invention provides a double-light source switching illuminating lamp and a working method thereof. The double-light source switching illuminating lamp comprises a lamp holder, a lamp cover, an installation and fixing device, a main light source, an auxiliary light source and a circuit device, wherein the lamp holder comprises a main light source socket and an auxiliary light source socket; the main light source and the auxiliary light source are in clamping connection or thread connection with the main light source socket and the auxiliary light source socket respectively and correspondingly; the circuit device comprises a ballasting start-up device, fire line and zero line electrodes which are used in an externally connected power source, and a light source switching controller; and the light source switching controller comprises a voltage-reduction anti-jamming circuit, a rectifying filter circuit, a voltage stabilization filter circuit, a voltage sampling circuit, a centralized control circuit, a main light source control and execution circuit and an auxiliary light source control and execution circuit. By the double-light source switching illuminating lamp, the automatic switching of the main and auxiliary light sources is controlled by the light source switching controller, continuous illumination is ensured, the problem of affecting the service life of the lamp due to repeated striking during the hot start of a high intensity discharge lamp and the problem of no-load power consumption when failures occur are solved, and cost and energy sources are saved.

Description

technical field

[0001] The invention relates to a lighting fixture, in particular to a double light source lighting fixture with two light sources in the same lighting fixture and its working method. Background technique

[0002] High-intensity discharge lamps (HID) are generally used for lighting in high-space areas such as outdoors of nuclear power plants, steam turbine platform equipment rooms of nuclear power plants, or nuclear islands to ensure the brightness of lighting. In order to prevent lighting from being affected by power outages, nuclear power plants are generally equipped with at least one set of emergency power generation devices such as diesel generators for emergency lighting. Under normal circumstances, high-intensity discharge lamps (HID) are equipped with only one light source in high-bay lighting fixtures. Due to the inherent delayed lighting characteristics of the high-intensity discharge lamp (HID) in the hot start state, the restart point of the high...
