Power strip

摘要

A power strip includes a power plug, an outlet block electrically connected thereto, and a light control module disposed inside the outlet block. The outlet block has at least one electrical socket and a luminous warning field. The light control module is for emitting a light to the luminous warning field in accordance with an output current of the electrical socket. The light control module defines at least two current ranges according to a rated current, where one of the current ranges is a safety current range, the upper limit of which is greater than 50% of the rated current. The light control module alters the light emitted to the luminous warning field in accordance with the correspondence between the output current and each of the current ranges, so as to make the luminousness of the luminous warning field to change in accordance with the output current.

1. A power strip, comprising:
a power plug having a power-input wire, an outlet block electrically connected to the power plug and having at least one electrical socket and a luminous warning field; a light control module disposed inside the outlet block for emitting a light to the luminous warning field in accordance with an output current of the electrical socket; and a current measurement unit disposed inside the power plug and electrically connected with the power-input wire of the power plug for measuring input current of the power plug and generating a DC signal to the light control unit; wherein the light control module defines at least two current ranges according to a rated current and alters the light emitted to the luminous warning field in accordance with the correspondence between the output current and each of the current ranges, so as to make the luminousness of the luminous warning field to change in accordance with the output current, wherein one of the current ranges is a safety current range, wherein the upper limit of the safety current range is greater than 50% of the rated current, wherein the light control module includes an interface for an external computer device being coupled thereto, and the rated current and parameter values of the current ranges are set up by the external computer.
