Problems solved by technology

[0006] 2. Three relays are used. Since the relay is a mechanical action electronic device, its life is far less than that of ordinary electronic components, and the electronic ballast is a non-resistive load, which will accelerate the shortening of its life. In the entire system life, its has become a short board

Abstract

The invention provides a lamp and a control device thereof. The lamp comprises at least two lamp tubes, at least two ballast modules, at least two interface modules and a control module, wherein the at least two ballast modules are connected with the at least two lamp tubes respectively; the at least two interface modules are connected with the at least two ballast modules respectively; and the control module is electrically connected with the at least two interface modules, and is used for controlling the turn-on and turn-off of the ballast modules in order to control the turn-on and turn-off of the at least two lamp tubes. The interface modules are controlled by using the control module in order to control the turn-on and turn-off of the output of corresponding ballast modules, so that a segmented dimming function can be realized for the lamp; and moreover, the lamp is simple in structure and is easy to assemble, the cost of a circuit is reduced, and convenience is brought to miniaturization of a product.

Description

technical field [0001] The invention relates to the technical field of lighting fixtures, in particular to a lighting fixture and a lighting fixture control device. Background technique [0002] At present, the most commonly used electronic ballast is the self-excited electronic ballast. This type of ballast is relatively cheap and has mature and reliable performance, but it has a single function. It only provides the driving function of the lamp tube and the necessary Segment dimming and the function of adding a small night light. [0003] Existing lamps that realize segmental dimming or adding night lights usually adopt the scheme of self-excited electronic ballasts and segmental controllers. Lights (or other related circuits) supply power to achieve the purpose of segmented control. Specifically, such as figure 1 As shown, the solution uses the controller to control the on and off of the relay 1-3 to control the self-excited ballast 1-2 and the power supply driven by t...
