Embodiment Construction

[0024] Such as Figure 1-Figure 5 As shown, the emergency light strip of the present invention includes: a driving power source 1 and a light strip body 2. Wherein, the driving power supply 1 and the light strip body 2 are connected through a DC bus 3. The light strip body 2 includes an illuminating light section 21 and an emergency light section 22.

[0025] The DC bus 3 includes a first DC bus 31, a second DC bus 32 and a third DC bus 33. Among them, the first DC bus 31 and the third DC bus 33 are all connected to the lighting lamp section 21, and the first DC bus 31, the second DC bus 32 and the third DC bus 33 are all connected to the emergency light section 22.

[0026] The driving power supply 1 includes a rectifier circuit 11, a battery 13, a detection circuit 14, a control chip 15 and a static switch 16.

[0027] The input terminal of the rectifier circuit 11 is connected to 220V commercial power, and the output terminal of the rectifier circuit 11 is connected to an input ...

Abstract

The invention discloses a three-wire emergency light strip, which includes a drive power supply and a light strip body; the drive power supply and the light strip body are connected through a DC bus, and the light strip body includes a lighting section and an emergency light section; the DC The bus bar includes a first DC bus bar, a second DC bus bar and a third DC bus bar; the drive power supply includes a rectifier circuit, a battery, a detection circuit, a control chip and a static switch. In this design, part of the structure of the main lighting strip replaces the function of the traditional emergency light strip, so that a part of the main lighting strip can be automatically converted into an emergency light strip for emergency lighting when the mains power is cut off. Compared with the traditional design, the present invention only needs three conductive buses for power supply, so that the production cost of the emergency light belt and the cost of corridor lighting construction are greatly reduced. In addition, compared with the traditional design, the present invention can save the occupied space and reduce the installation space of the lighting strip to half of the original one.

Description

Technical field [0001] The invention relates to a lamp, in particular to a three-wire emergency light belt. Background technique [0002] The lighting in the traditional corridor usually uses a combination of main lighting and emergency lighting. Because the LED light strip has the characteristics of high brightness, low energy consumption and long life, it is very suitable for main lighting and emergency lighting of corridors. [0003] At present, in the existing design of LED strip lighting on the market, independent main lighting strips and independent emergency lighting strips are respectively provided, and the main lighting strips and emergency lighting strips are both provided with independent driving power supplies. When the mains power supply is normal, the main lighting strip will be driven to work after the mains is rectified, but the emergency lighting strip will not work; when the mains power failure occurs, the battery-driven emergency lighting strip will work, and th...
