  • Light emitting diode replacement bulbs
    Patent number: 8736171
    Abstract: An illumination device comprises a bulb connector, a body structure and an insulating layer between the bulb connector and a first end portion of the body structure. The illumination device further comprises a first plurality of light emitting diodes arranged towards the first end portion of the body structure and a second light source comprising at least one light emitting diode arranged towards the second end portion of the body structure. A heat sink extends from the body structure and a controller within the body structure receives power through the bulb connector and supplies power to each of the light emitting diodes. As such, the illumination device can directly replace an incandescent bulb. Thus for example, the illumination device can replace an incandescent bulb of a traffic light without requiring changes to the compartment, fixture, reflector, or window/lens.
