Abstract: An LED module includes light sources that are disposed on a surface of a circuit substrate and each of which has LED chips and a wavelength conversion member covering the LED chips. The light sources include first light sources and second light sources. LED chips in each of the first light sources differ in number from LED chips in each of the second light sources. The circuit substrate includes a conductive pattern that is connected with the first and second light sources, and that forms each of one or more series circuits along with at least one of the first light sources and at least one of the second light sources.

Abstract: An LED module includes a circuit substrate, a light source and a lens. The light source includes first and second LEDs that differ in chromaticity. The circuit substrate is provided with conductors for driving the first and second LEDs independently. The lens includes a hollow, on a side of the circuit substrate, inside which the light source is present. An inside of the hollow is a light entrance surface. An opening of the hollow has a circular shape. The first and second LEDs of the light source are arranged to have point symmetry.

Abstract: A lighting fixture includes an outer surface with pairs of fastening holes to receive LED lighting devices. The devices include an insulating base substrate, an LED module engaging the base substrate and including positive and negative power supply input terminals, and an insulating device housing shaped to cover the base substrate and the LED module when engaged therewith. A plurality of terminal board modules are integral to the device housing and effective to electrically couple respective external power supply conductors to the power supply input terminals of the LED module. The base substrate and the device housing further include a pair of through holes corresponding to an associated pair of holes on the fixture surface. When a fastener couples the base substrate and the device housing to the fixture, the LED module is insulated with respect to the fastening device and outer surface.
