AERONAUTICAL LIGHT CONTROL DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an aeronautical light control device in which heat evolution accompanying turning on/off control of an aeronautical light can be suppressed and a life operation number of times can be extended to improve safety, reliability, and a life.;SOLUTION: A light control device 12 is housed in a completely tightly closed rubber mold frame 11. In a turning on/off circuit of an aeronautical light 1, an FET4 and an auxiliary relay 3 are provided. A current value determination unit 7, a temperature determination unit 9, and a control unit 10 are provided. The current value determination unit 7 determines whether a measured value of current flowing through the turning on/off circuit is larger or smaller than a reference value. The temperature determination unit 9 determines whether a measured temperature in the rubber mold frame 11 is higher or lower than a reference temperature. On the basis of determination results of the current value determination unit 7 and the temperature determination unit 9, the control unit 10 controls the FET 4 and the auxiliary relay 3 by performing switching over between a combination mode in which the FET 4 and the auxiliary relay 3 are used together and a single mode in which only the FET 4 is used.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2020,JPO&INPIT
