Abstract

A high power LED Housing consisting of one or more LED to form a LED assembly fitted into a metal body having an upper portion with a gripping means and a lower portion with a fitting means and a base. The LED assembly is connected by electrical wire to a base of the metal body, the base of the metal body having an electrical contact.

By means of the gripping means, the LED housing can be installed or removed from a socket shaped to receive the LED housing.

The LED housing can be assembled into panels of LED housing which can be fitted with electrical and electronic circuits to monitor and control the operation of the LED housing for various applications.
