1. An automotive lamp device comprising:
- a lamp housing in which a first lamp including an LED light source operable at a first level of voltage or current and a second lamp including an LED light source operable at a second level of voltage or current different from the first voltage or current can be disposed at a predetermined position at different times; and
a lamp driver module connected to the lamp housing for supplying, if the first lamp is disposed at the predetermined position of the lamp housing, to the first lamp the first level of voltage and/or current or supplying, if the second lamp is disposed at the predetermined position of the lamp housing, to the second lamp the second level of voltage and/or current, which is different from the first level of voltage and/or current, and the first operable level of voltage or current and the second operable level of voltage or current are detected by the lamp driver module.

Abstract
An automotive lamp device is provided. The automotive lamp device includes a lamp housing into which a first lamp or a second lamp is inserted and which includes a plurality of lines, and a lamp driver module which is connected to a first line among the plurality of lines, supplies a first level of voltage and/or current to the first lamp if the first lamp is inserted into the lamp housing, and supplies a second level of voltage and/or current to the second lamp if the second lamp is inserted into the lamp housing.

7. An automotive lamp device comprising:
-
a lamp housing in which a first lamp including an LED light source having a first identification resistor and a second lamp including an LED light source having a second identification resistor different from the first identification resistor can be disposed at a predetermined position at different times; and a lamp driver module including a lamp driver circuit and a resistor circuit, wherein; if the resistor circuit is connected to the first identification resistor, the first identification resistor and the resistor circuit form a voltage divider circuit, and the voltage divider circuit supplies a first level of output such that the lamp driver circuit supplies to the first lamp a first level of voltage and/or current in response to the first level of output; and if the resistor circuit is connected to the second identification resistor, the second identification resistor and the resistor circuit form the voltage divider circuit, and the voltage divider supplies a second level of output different from the first level of output such that the lamp driver circuit supplies to the second lamp a second level of voltage and/or current, which is different from the first level of voltage and/or current, in response to the second level of output. - View Dependent Claims (8)
