  • Publication number: 20170067622
    Abstract: Various examples of an LED lighting module and a lamp having the LED lighting module are described. An LED lighting module may include an LED lighting member, configured to emit light and including at least one LED, and a monolithic base that is substantially cylindrically shaped with a cavity therein. The monolithic base may include a first distal end, a second distal end opposite the first distal end, a top surface located at the first distal end and including a hole intercommunicating with the cavity, and an exterior surface disposed between the first and the second distal ends. The LED lighting member may be disposed on the top surface. The exterior surface may include one or more screw threads thereon.

  • Publication number: 20120176047
    Abstract: The present invention provides a light emitting diode (LED) device. The LED device include a driver, a first LED coupled in series with the driver, and an impedance-providing component coupled in parallel with the first LED and in series with the driver. The impedance-providing component provides a shunt impedance having a value that varies in positive proportion with a variation in an ambient temperature. The driver is respectively coupled in series with the first LED and the at least one impedance-providing component. The driver provides a drive current divided to flow through the first LED and the at least one impedance-providing component according to the shunt impedance and the internal impedance.
