Title:
LED LAMP, LUMINAIRE, AND LIGHTING FIXTURE
Document Type and Number:
Japanese Patent JP2013143349
Kind Code:
A
Abstract:

To make color matching easier than usual.

Once a ferrule 12 is mounted on a first lamp socket 3, a pair of individual terminal pins 14 are connected to reception-side terminals 31 and 32, respectively. Similarly, once a ferrule 13 is mounted on a second lamp socket 4, a common terminal pin 15 is connected to a reception-side terminal 41. A first lighting circuit part 21 and a second lighting circuit part 22 can adjust electric supply amounts individually under PWM control. An LED lamp 1 therefore includes a plurality of light source parts 10A and 10B which differ in light color (color temperature) from each other, so that a plurality of LED lamps differing in light color need not be used and color matching is made easier than usual.
