| 摘要 |
A lighting apparatus includes a lighting circuit including at least one light-emitting device, e.g., a string of LEDs, and at least one current sense diode configured to generate a forward voltage responsive to a current passing through the at least one light-emitting device. The apparatus further includes a control circuit configured to control the lighting circuit responsive to the generated forward voltage. In some embodiments, the least one light-emitting device includes the at least one current sense diode. In some embodiments, the at least one current sense diode is connected in series with the at least one light-emitting device.
