Abstract

PURPOSE:To provide the cold light which can be effectively utilized for IR rays, etc., to be released from the rear surface of a cold mirror. CONSTITUTION:This cold light has an incandescent lamp 2, the cold mirror 3 which is provided behind the incandescent lamp 2, reflects visible rays and allows transmission of IR rays and solar batteries 5 which are provided behind the cold mirror 3. The output of the solar batteries 5 is recommended to be utilized as electric power of a fan 9 for discharging the air behind the cold mirror 3 to the outside and the output of the solar batteries 5 is also recommended to be utilized by accumulating the output in a storage battery 6. As a result, the IR rays, etc., released from the rear surface of the cold mirror 3 which are heretofore uselessly discarded are effectively utilized by converting the IR rays, etc., to electric energy by the solar batteries 5 and are more particularly utilized as a power source of the fan 9 to prevent the temp. rise of the cold light, by which the life of the cold light is prolonged and an accident, such as fire, is prevented.

2. Description of the Related Art A floodlight using a cold mirror as a reflecting mirror that reflects visible rays and transmits infrared rays so that an illuminated object is not heated by radiant heat is widely used in various studios, exhibition halls, etc. Has been done. However,
When a cold mirror made of glass is used as a downlight, heat rays including infrared rays pass through the cold mirror and are radiated from the back of the cold mirror, which raises the temperature of the air and parts behind it, shortens the life of the device, and reduces the life of the device. There was a risk that the ceiling could get hot and cause a fire. In addition,
Even if there is no such danger, the thermal energy radiated from the back surface of the cold mirror is not used at all and is thrown into the atmosphere, which is a great waste of energy.

A temperature sensor 7 is attached at a proper position in the housing 1 or at a proper position on the solar cell mounting plate 4. When the temperature of the mounting portion exceeds a predetermined allowable temperature, the output of the temperature sensor 7 is output. Based on this, the control circuit 8 operates to pass a current from the storage battery 6 to the blower 9 to operate the blower 9 to take in air from the outside into the housing 1 and discharge the air on the back surface of the cold mirror 3 to the outside.
Cool the entire cold light. Therefore, overheating of the entire cold light can be prevented, and even when this is used as a downlight, it is possible to promote the circulation of air around the ceiling and prevent the risk of a fire or the like.
The electric energy stored in the storage battery 6 can be used for any purpose other than the operation of the blower 9, and the energy such as infrared rays that has passed through the cold mirror 3 can be effectively used without waste.
