ABSTRACT:
An apparatus for monitoring a lamp includes a base body, a sensor and a signal transfer pattern. The base body includes a first face having a first region corresponding to a lamp and a first peripheral region disposed around the first region, and a second face having a second region corresponding to the first region and a second peripheral region corresponding to the first peripheral region. The sensor is disposed in the first region, and outputs a sensing signal in response to a working status of the lamp. The signal transfer pattern is disposed in the second peripheral region, and transfers the sensing signal. Therefore, the apparatus for monitoring the lamp senses abnormal working lamps, so that normally working lamps may be protected from being damaged, shortening of lifetime, causing a fire, etc.
