VEHICULAR LAMP |
| 摘要 |
A vehicular lamp has a light-emitting portion connected in series to an input terminal to which a power supply voltage based on an on-board battery is configured to be applied, and having a plurality of light-emitting elements connected in series, a series connection circuit having a first current limiting resistor and a second current limiting resistor, which is inserted in series between the input terminal and the light-emitting portion, a resistor switching switch connected in parallel to one of the first current limiting resistor and the second current limiting resistor, bypass switches, each of which is connected in parallel to a required one of the light-emitting elements in the light-emitting portion, and a control circuit that turns off the resistor switching switch when at least one of the bypass switches is turned on. |

1. A vehicular lamp, comprising:
a light-emitting portion connected in series to an input terminal to which a power supply voltage based on an on-board battery is configured to be applied, and comprising a plurality of light-emitting elements connected in series; a series connection circuit comprising a first current limiting resistor and a second current limiting resistor, which is inserted in series between the input terminal and the light-emitting portion; a resistor switching switch connected in parallel to one of the first current limiting resistor and the second current limiting resistor; bypass switches, each of which is connected in parallel to a required one of the light-emitting elements in the light-emitting portion; and a control circuit that turns off the resistor switching switch when at least one of the bypass switches is turned on. |
