A light source lighting device and a lighting installation
Document Type and Number:
Japanese Patent JP6173042
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a light source lighting device that can be connected with a high-voltage light source without using a power supply circuit with a high capacity.SOLUTION: A light source lighting device 12 that can be connected with a light source 13 comprises two LED lighting circuits 12a and 12b respectively having second output capacitors 21a and 21b. In a state that a connector 22b is connected with a terminal base 22a and an output connector 23b is attached to an output terminal base 23a (that is, in a state that the light source 13 is connected with the light source lighting device 12), the light source 13 is connected in parallel to a series circuit formed so that the second output capacitors 21a and 21b of the LED lighting circuits 12a and 12b are connected in series. A DC power for lightening the light source 13 is supplied from the series circuit to the light source 13.
