Abstract:
A light-emitting module includes a module substrate, semiconductor light-emitting elements and a connection substrate. On one face of the module substrate, a conductive layer is formed. The semiconductor light-emitting elements and the connection substrate are mounted on the conductive layer of the module substrate. Electric wires, which extend from a lighting circuit, are connected to the connection substrate. Power is supplied to the semiconductor light-emitting elements through the connection substrate and the conductive layer of the module substrate.
Abstract:
A lamp (100) includes a main body (11) and a removable cover (10). The main body (11) includes a lamp housing (111), a printed circuit board (112), light emitting elements (113), and a threaded base (114). The lamp housing (111) defines a socket (115) receiving the printed circuit board (112) and the at least one light emitting element (113) therein. The printed circuit board (112) is electrically connected to the light emitting elements (113) and fixed in the socket (115). The removable cover (10) includes a light-transmission portion (101) and a connection portion (102) which connects to the end of the lamp housing (111) defining the socket (115). The light-transmission portion (101) is opposite to the socket (115). Light from the at least one light emitting element (113) emits through the light-transmission portion (101).
