## Abstract

A hanging plant growth lighting device with spectrum adjustment function includes a frame, a power source module, a plurality of light source modules, a dimming module and a hanging structure. The frame includes a first frame bar, a second frame bar and a connecting portion. The power source module is disposed in the connecting portion. The light source modules are electrically connected to the power source module. The two ends of each of the light source modules are fixed at the first frame bar and second frame bar respectively. The dimming module is electrically connected to the power source module. The hanging structure includes a retractable structure, two first hanging rings fixed on the first frame bar and two second hanging rings fixed on the second frame bar. The retractable structure is connected to the two first hanging rings and the two second hanging rings.

## Claims

### Claim 1
