Embodiment Construction
[0019] Such as figure 1 , figure 2 As shown, the lighting device 100 according to the embodiment of the present invention includes a ring-shaped substrate 3 and a power supply unit 2 . The power supply unit 2 receives AC power from an external AC power supply AC1 and supplies lighting power to the light source unit 1 having the light emitting element 11 .
[0020] The power supply unit 2 includes an input unit 21 , a rectification unit 22 , a conversion unit 23 , and a control unit 24 . The input unit 21 is electrically connected to the AC power supply AC1. The rectification unit 22 rectifies the AC power supplied from the AC power source AC1 via the input unit 21 . The conversion unit 23 converts the output power of the rectification unit 22 into predetermined DC power. The control unit 24 controls the conversion unit 23 .
[0021] On the substrate 3 , an input unit 21 , a rectification unit 22 , a conversion unit 23 , and a control unit 24 are sequentially provided al...

The invention provides a lightening device and an illumination device using the lightening device. The object of the invention is to improve anti-noise performance and improve performance aiming at radiation noises. The lightening device (100) is provided with an annular base plate (3) and a power supply part (2). The power supply part is used to receive AC power from an external AC power supply, and is used to supply a light source part (1) provided with an illuminating element (11) with lightening power. The power supply part is provided with an input part (21), a rectification part (22), a conversion part (23), and a control part (24). The base plate is sequentially provided with an input part, a rectification part, a conversion part, and a control part along a peripheral direction. The lightening device is also provided with a signal line (L1). The signal line is formed on the substrate, and is used to flow the control signal provided from the control part to the conversion part. The signal line is laid in the way of the control signal flowing in the direction opposite to the above mentioned direction.
Description
technical field [0001] The present invention generally relates to a lighting device and an illuminating device using the lighting device, and more specifically, to a lighting device that supplies lighting power to a light source unit having a light emitting element, and an illumination device using the lighting device. device. Background technique [0002] Conventionally, a lighting fixture (illumination device) using a light emitting element such as an LED (Light Emitting Diode) as a light source is known, and is disclosed in Document 1 (Japanese Patent Application Laid-Open No. 2012-146666 ), for example. The lighting fixture described in Document 1 is a lighting fixture for a general house that is attached to a ceiling light pan as a wiring fixture, and the ceiling light pan is installed on a fixture mounting surface. This lighting fixture illuminates a room using light radiated from a light source unit having a plurality of light emitting elements mounted on a substrate...
