Document Type and Number:
WIPO Patent Application WO/2016/157318
Kind Code:
A1
Abstract:
This vehicle LED lamp lighting circuit includes: a switching device exposed to water which switches between a first state where a reference node and a first contact have electrical continuity and a second state where the reference node and a second contact have electrical continuity; a first LED lamp which is formed of at least one first LED element and which has one end connected to the reference node and has the other end connected to the second contact; a second LED lamp which is formed of at least a second LED element and which has one end connected to the second contact and has the other end connected to a grounded ground wire; and a bypass circuit which has a switching element for bypassing having one end connected to the second contact and having the other end connected to the ground wire, and which controls the switching element for bypassing according to a first potential difference between the reference node and the second contact and a second potential difference between the second contact and the ground wire.
