Abstract
A full-color illuminating unit includes a first circuit board which is a disk having a hole and a plurality of green lights and red lights installed around the hole. A second circuit board which is a disk includes a blue light installed thereon. A first housing has an isolation plate integrally connected with an inner periphery thereof, thus separating the first housing into a first cavity and a second cavity. The first circuit board is installed in the first cavity while the second circuit board is installed in the second cavity. A boss protrudes from the isolation plate to the first cavity and is in communication between the first cavity and the second cavity. The first circuit board is positioned in place, with the periphery of the hole thereof being around the boss. The blue light is positioned in the boss, with a portion thereof protruding beyond an opening of the boss. A second housing is attached to the first housing, thus enclosing the second circuit board.
