Abstract
The present disclosure provides a LED metal substrate and a LED module. An insulator is provided to cover an electrode or a side surface of a metal layer in the LED metal substrate, or provided on an original creepage path between the electrode and the metal layer in the LED metal substrate to form a new creepage path with increased creepage distance, in order to increase the breakdown voltage between the electrode and the metal layer. It is possible to avoid a phenomenon that an electric arc is generated between the electrode and the metal layer when a relative high voltage applied by the electrode during a breakdown test. So that the breakdown voltage of the LED metal substrate with an insulator reaches higher than that of a LED metal substrate without the insulator in the same dimension, and a technical problem in the art may be solved.
