20110089831 | BULB-SHAPED LAMP AND LIGHTING DEVICE - Provided is a bulb-type lamp including a lightweight housing with great handleability. An LED light bulb ( | 04-21-2011 |
20120002421 | BULB-SHAPED LAMP AND LIGHTING DEVICE - A bulb-type lamp having both heat dissipation and size/weight reduction properties with a lower thermal load on a lighting circuit. An LED module is mounted in a case with a base member to allow dissipation of heat. An LED mount member closes another end of the case and allows conduction of heat to the case. A lighting circuit receives power via the base member. The lighting circuit is disposed inside a circuit holder. An air space exists between the circuit holder and both the case and the mount member. The lighting circuit is isolated from the air space by the circuit holder. A relationship 0.5≦S | 01-05-2012 |
20120044684 | BULB-TYPE LAMP AND LIGHTING DEVICE - Provided is a bulb-type lamp including a lightweight housing with great handleability. An LED light bulb comprises: an LED module on which LEDs are mounted; a cylindrically-shaped case having openings at both ends, which are first and second ends; a mount member on a front surface of which the LED module is mounted, the mount member closing a corresponding one of the openings of the case by being in contact with an inner circumferential surface of the first end of the case; a base member attached to the second end of the case; and a lighting circuit that is disposed inside the case. A wall thickness of the case is in a range of | 02-23-2012 |

20130201700 | LAMP - A lamp comprises a light emitting module including a substrate and LEDs mounted on the substrate, a heat sink that is cylindrical and that discharges heat produced during light emission by the LEDs, a base provided at one end of the heat sink, a mounting member having a front surface whereon the light emitting module is mounted, and a circuit unit positioned partially in the heat sink, receiving power through the base and causing the light emitting element to emit light. The mounting member is in contact with the heat sink so that the heat produced during light emission is transmitted to the heat sink. The circuit unit includes a circuit board and a plurality of electronic components mounted on the circuit board. The circuit board or at least one of the electronic components is thermally connected to the mounting member through a thermally conductive member. | 08-08-2013 |
