Control system of fluorescent lamp and LED lamp integrated energy-saving lamp

Abstract

The invention discloses a control system of a fluorescent lamp and LED lamp integrated energy-saving lamp, which comprises a half bridge circuit, an LC resonance and voltage-reducing rectification circuit, a control circuit, a self-oscillating half bridge drive circuit and an LED drive circuit, wherein the control circuit selects an LED lamp or a fluorescent lamp to work by judging whether the on and off of an external power supply and the on and off interval time of the power supply are within a preset time; and the LC resonance and voltage-reducing rectification circuit supplies the power to the LED lamp and the fluorescent lamp at the same time. When a user needs high brightness, the fluorescent lamp emits light; and when the user needs low brightness, the LED lamp emits light; therefore, a dimming circuit does not need to be increased to adjust the light of the energy-saving lamp, and two sets of power supply system do not need to be used for supplying power to the LED lamp and the fluorescent lamp respectively. Therefore, the fluorescent lamp and LED lamp integrated energy-saving lamp has the advantages of energy conservation, low cost, high performance, convenient operation and simple structure.

Description

technical field [0001] The invention relates to the field of lighting equipment, in particular to a control method and system for an energy-saving lamp integrated with a fluorescent lamp and an LED lamp. Background technique [0002] At present, fluorescent lamps are widely used in daily life and working environment due to their advantages of high brightness, soft light, and high color temperature. When the lighting in passages and other places is dimmed, the fluorescent lamps in the prior art cannot meet the dimming requirements of these places. In order to achieve the above purpose of low-light lighting, the prior art adopts the following methods: [0003] 1. In addition, LED lamps are installed as supplementary light sources for fluorescent lamps. When weak lighting is required, turn off the fluorescent lamps and turn on the LED lamps. The disadvantage is that another set of power supply and control circuits for the LED lamp must be built, and when the power switches of...

Problems solved by technology

The disadvantage is that it is necessary to build another set of power supply and control circuits for LED lamps, and when the power switches of fluorescent lamps and LED lamps are not at the same place, it will cause inconvenience to the operation

[0004] 2. Some dimmable energy-saving lamps are also used in the existing technology. The disadvantages are: a special device for dimming must be added additionally. The structure is complex, the life is short, the cost is high, and the original ballast cannot be reused.

[0005] Therefore, the lighting source in the prior art can no longer meet the needs of people, and there is an urgent need for a lighting control method and system that is easy to operate, simple in structure, energy-saving, and low in cost.
