Embodiment Construction

[0026] Such as Figure 1-Figure 6 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 lamp strip body 2 are connected through a DC bus 3 , and the lamp strip body 2 includes at least one lighting segment 21 connected in parallel to the DC bus 3 .

[0027] The driving power supply 1 includes a rectification circuit 11 , a battery 13 , a detection circuit 14 , a control chip 15 , a static switch 16 and a current control circuit 17 .

[0028] Wherein, 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 the input end of the detection circuit 14, and the rectification circuit 11 is used to supply the lamp belt through the static switch 16. Body 2 provides direct current.

[0029] The battery 13 is connected to the other in...

Abstract

The invention discloses an emergency light strip capable of adjusting brightness, which includes a driving power supply and a light strip body, the driving power supply and the light strip body are connected through a DC bus, and the light strip body includes at least one lighting device connected in parallel on the DC bus. lamp segment. The drive power supply includes a rectification circuit, a battery, a detection circuit, a control chip and a static switch. The invention uses a part of the lighting strip to replace the emergency lighting strip in the traditional way, so that a part of the lighting strip can be automatically converted into an emergency lighting strip for emergency lighting when the mains power is cut off. Compared with the traditional design that requires four busbars, this design only needs two conductive busbars to realize power supply, and the required driving power and the number of LED lamp beads are half of the traditional design, which greatly reduces the production cost. In addition, the present invention is provided with an LED lamp bead brightness adjustment circuit, which can flexibly adjust the brightness of the lighting strip in emergency situations according to actual needs.

Description

technical field [0001] The invention relates to a lamp, in particular to an emergency lamp belt capable of adjusting brightness. 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 corridor main lighting and emergency lighting. [0003] At present, the existing main lighting strips and emergency lighting strips in the market are designed in combination with independent main lighting strips and emergency lighting strips respectively. When the power supply is normal, only the main lighting belt works, and the emergency lighting belt does not work; when the mains power failure occurs, the emergency lighting belt works, but the main lighting belt does not work. This design requires at least four conductive busbars, which has high production costs and i...
