  • Patent number: 9383081
    Abstract: The invention relates to an electric lamp (102) comprising a primary semiconductor light source (104) in thermal communication with a primary reflector (106). Herein, the primary reflector (106) is reflective, transparent and/or translucent. The primary reflector (106) is configured for transferring heat generated by the primary semiconductor light source (104) during operation away from said primary semiconductor light, source (104). As a result, the electric lamp (102) according to the invention effectively reduces the number of parts comprised in the electric lamp (102), thereby lowering the costs of manufacturing the electric lamp (102).

  • Patent number: 9316383
    Abstract: A lighting device has a plurality of LEDs of at least two types connected in series. At least one of the LEDs of the first type and LEDs of the second type is connected in parallel to a resistor assembly, such that the temperature-dependent resistance of the resistor assembly stabilizes a ratio of luminous flux output at different junction temperatures of the LEDs.

  • Patent number: 9249965
    Abstract: There is provided a lighting device 100 comprising a light source, a driver arranged for powering the light source, which is separated in space from the light source. The lighting device has two separate heat sinks, a light source heat sink 112 to which the light source is thermally coupled, and a driver heat sink 115 to which the driver is thermally coupled. The light source heat sink and the driver heat sink are separated by an air gap 114 to provide thermal decoupling of the light source heat sink and the driver heat sink.

  • Patent number: 9253849
    Abstract: In a lighting device, sets of LEDs are employed using the natural characteristics of the LEDs to resemble incandescent lamp behavior when dimmed, thereby obviating the need for sophisticated controls. A first set of at least one LED produces light with a first color temperature, and a second set of at least one LED produces light with a second color temperature. The first set and the second set are connected in series, or the first set and the second set are connected in parallel, possibly with a resistive element in series with the first or the second set. The first set and the second set differ in temperature behavior, or have different dynamic electrical resistance. In various embodiments, the sum of the currents provided to the first and second sets may be substantially equal to a magnitude of an input current.

  • Publication number: 20130201677
    Abstract: A lighting device has a plurality of LEDs connected in series. In the lighting device, a first LED assembly has LEDs of a first type having a first luminous flux output decreasing as a first function of its junction temperature. A second LED assembly has LEDs of a second type having a second luminous flux output decreasing as a second function of its junction temperature different from the first function. At least one of the LEDs of the first type and LEDs of the second type is connected in parallel to a resistor assembly having a temperature-dependent resistance. The temperature dependence of the resistance stabilizes a ratio of the first luminous flux output to the second luminous flux output at different junction temperatures of the first LED assembly and the second LED assembly.
