Integrated lamp circuit with ultraviolet sterilization function and LED lighting function

Abstract

The invention discloses an integrated lamp circuit with an ultraviolet sterilization function and an LED lighting function. The integrated lamp circuit comprises an electronic ballast circuit, a mercury ultraviolet lamp tube, a high-frequency rectifying circuit, an LED light-emitting module and a pulse control switch circuit. The integrated lamp circuit is connected with the mains supply through an external control switch. When an external control switch is switched on, the integrated lamp is switched from the off state to the on state, the current flowing through the LED light-emitting moduleis the current output by the electronic ballast. Current flows through the LED light-emitting module and is in a light-emitting state. When the integrated lamp is in an LED lighting state, if the external control switch is switched once, no current passes through the LED light-emitting module and the LED light-emitting module does not emit light, and the ultraviolet lamp tube emits ultraviolet light. The circuit has the advantages of simple structure, lower cost and higher competitive advantages in technology and cost.

Description

technical field [0001] The invention relates to an integrated lamp circuit, in particular to an integrated lamp circuit with ultraviolet sterilizing function and LED lighting function. Background technique [0002] With the continuous improvement of people's public health requirements, many public places will be required to regularly disinfect. Ultraviolet sterilizing method is a fast and effective surface sterilizing method, which has been promoted and applied to various public places, including many places with LED lighting. [0003] Because ultraviolet rays are harmful to the human body, under normal circumstances, when the ultraviolet germicidal lamp is turned on, people will stay away from the scene, and at the same time, in order to save energy, the LED lighting at this time will be turned off. When the LED lighting needs to be turned on, there are usually people on site, and the ultraviolet germicidal lamp needs to be turned off at this time. So in general, LED ligh...

Problems solved by technology

[0005] At present, some designers have proposed an integrated lamp circuit with ultraviolet sterilization function and LED lighting function. In this integrated lamp circuit, both an electronic ballast is used to drive the mercury ultraviolet lamp tube and an LED drive power supply is used to drive the LED light-emitting module. In fact, it is The simple combination of ultraviolet germicidal lamps and LED lighting not only has a complex product structure, but also has high costs, and does not have competitive advantages in terms of technology and cost.
