    摘要: Provided is a lighting device which can be dimmed and subjected to change in color temperature of the lighting color in accordance with a dimming level. To the lighting device, AC power under phase-controlled is supplied. The lighting device is provided with a light emitting elements array and a switching unit. The light emitting elements array includes a plurality of light emitting elements, which are two or more types of light emitting elements having different lighting colors. The switching unit switches an electrical connections between the light emitting elements included in the light emitting elements array so as to change the number of light emitting elements inserted in series to a power supply path and the proportion of numbers of light emitting elements per lighting color among the number of the inserted light emitting elements in accordance with a voltage supplied to the light emitting elements array.

    摘要: 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≦S1/S2≦3.0, is satisfied where S1 denotes an area of a portion of the mount member in contact with the case and S2 denotes an area of the portion of the mount member in contact with a substrate of the LED module.
