Dual-light-source converting illumination lamp

Abstract

The invention provides a dual-light-source converting illumination lamp, comprising a lamp base, a lamp cover, a mounting and fixing device, a main light source, an auxiliary light source and a circuit device. The lamp base comprises a main light source socket and an auxiliary light source socket; the main light source and the auxiliary light source are respectively and correspondingly clamped or screwed with the main light source socket and the auxiliary light source socket; the circuit device comprises a ballast turning-on device, live wire and null wire electrodes which are externally connected with a power supply, and a light source conversion controller; the light source conversion controller comprises a voltage reduction anti-jamming circuit, a rectifying and filtering circuit, a voltage stabilizing and filtering circuit, a main light source current sampling circuit, a centralized control circuit, a main light source control executing circuit and an auxiliary light source control executing circuit. According to the dual-light-source converting illumination lamp provided by the invention, the main light source and the auxiliary light source are automatically converted through the control of the light source conversion controller, so that the uninterrupted illumination is ensured; the problem that the service life of the lamp is influenced by repeatedly lightening when a high-intensity discharge lamp is in warm start, and the problem of no-load power consumption when faults exist can be solved; and the cost and the energy 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. 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-intensity discharge la...
