Abstract

An LED device and a bracket thereof. The bracket includes a first photo-etched metal part, composed of a first electrode and a chip placement layer stacked thereon, wherein an area of the chip placement layer is greater than an area of the first electrode; a second photo-etched metal part, composed of a second electrode and a connection layer stacked thereon; wherein a first insulation trench is provided between the first electrode and the second electrode, and a second insulation trench is provided between the chip placement layer and the connection layer. The LED device and the bracket thereof can increase the placement area for placing LED chips, thereby improving the luminance of the LED device.
