Bright-from-the-start compact fluorescent lamp with lumen-shift elimination circuitry |
摘要 |
A lamp including a primary light source and a secondary light source, and a secondary light source control circuit configured to provide an operating voltage to the secondary light source. The secondary light source control circuit including a resistance element having an initial resistance which changes in response to being exposed to a temperature above a predetermined threshold. The secondary light source control circuit including a charging branch resistance-capacitance time constant that is configured to change with a change in the resistance element resistance. |

1. A lamp comprising:
a primary light source; a secondary light source; a secondary light source control circuit configured to provide an operating voltage to the secondary light source; the secondary light source control circuit including a resistance element having an initial resistance changeable in response to the resistance element being exposed to a temperature above a predetermined threshold; and the secondary light source control circuit including a charging branch resistance-capacitance time constant that is configured to change with a change in the resistance element resistance. |
