Embodiment Construction

[0025] Such as Figure 1-Figure 5 As shown, the emergency light strip of the present invention includes: a driving power supply 1 and a light strip body 2 . Wherein, the driving power supply 1 and the light strip body 2 are connected through the DC bus 3 , the light strip body 2 includes a lighting section 21 and an emergency light section 22 , and both the lighting section 21 and the emergency light section 22 are connected to the DC bus 3 in parallel. The emergency light section 22 is connected to the DC bus 3 through a rectifier bridge 221 .

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

[0027] The input end of the rectification circuit 11 is connected to the 220V mains, and the output end of the rectification circuit 11 is respectively connected to an input end of the static switch 16 and an input end of the detection circuit 14; Provides direct current.

Abstract

The invention discloses an emergency lamp belt. The emergency lamp belt comprises a driving power supply and a lamp belt body, wherein the driving power supply and the lamp belt body are connected through a dc bus; the lamp belt body comprises an illuminating lamp segment and an emergency lamp segment; the illuminating lamp segment and the emergency lamp segment are connected to the dc bus in parallel; the emergency lamp segment is connected with the dc bus through a rectifier bridge; the driving power supply comprises a rectifier circuit, a battery, a detecting circuit, a control chip and a static switch. According to the emergency lamp belt disclosed by the invention, the emergency lamp belt in a conventional manner is replaced with a part of an illuminating lamp belt, so that a part of the illuminating lamp belt can automatically turn into the emergency lamp belt to perform emergency illumination under the situation that commercial power is in power failure; besides, only two buses are arranged in the emergency lamp belt disclosed by the invention, compared with the four conductive buses in the conventional design, the emergency lamp belt disclosed by the invention has the advantage that the production cost of the emergency lamp belt disclosed by the invention and the cost of corridor illuminating construction are greatly reduced; in addition, the occupied space can be saved, and the mounting space of the illuminating lamp belt is reduced to one half of that of the original illuminating lamp belt.

Description

technical field [0001] The invention relates to a lamp, in particular to an emergency lamp belt. Background technique [0002] The lighting in traditional corridors usually adopts a combination of main lighting and emergency lighting. Because the LED light strip has the characteristics of high lighting brightness, low energy consumption and long life, it is very suitable for main lighting and emergency lighting of corridors. [0003] At present, among the existing design methods of LED strip lighting on the market, independent main lighting strips and independent emergency lighting strips are provided respectively, and the main lighting strips and emergency lighting strips are both provided with independent driving power sources. When the mains power supply is normal, the mains is rectified to drive the main lighting strip to work, but the emergency lighting strip does not work; when the mains power failure occurs, the battery drives the emergency lighting strip to work, an...
