LOW LOSS INPUT CHANNEL DETECTION DEVICE FOR A DIRECT CURRENT POWERED LIGHTING SYSTEM |
摘要 |
A device which includes a plurality of input channels selectively connected to the power source (102) for providing current to the lamp. For each input channel, the device includes a corresponding current sensing component (202, 204) connected to the input channel, and a corresponding bypass switch (206, 208) connected in parallel with the current sensing component. Each current sensing component produces a measurable signal as a function of current that is provided by the corresponding input channel. The device includes a controller (302) connected to the current sensing components and the bypass switches. The controller identifies the input channel that is providing current to the lamp as a function of the measurable signals and controls the bypass switches based on the identified input channel. Particularly, the controller operates each bypass switch in a closed mode when the corresponding input channel is the identified channel. |
