摘要	Light, which has been produced by a semiconductor device (11) and has wavelengths falling within the range of 630nm to 680nm, is propagated through a plastic fiber (12) provided with a core (12a) containing a polymethyl methacrylate as a principal constituent. The temperature of the semiconductor device is adjusted by a temperature adjusting system (21) comprising a heater (22) for heating the semiconductor device, a temperature detector (thermistor) (17) for detecting the temperature of the semiconductor device and feeding out a temperature detection signal (S), and a control circuit for controlling actuation of the heater in accordance with the temperature detection signal in order to set the temperature of the semiconductor device at a predetermined target value that is lower than the highest temperature assumed to occur under an environment, in which the semiconductor device is located.
其他摘要	已经由半导体器件（11）产生并具有落在630nm至680nm范围内的波长的光通过设置有包含聚甲基丙烯酸甲酯作为主要成分的芯（12a）的塑料纤维（12）传播。通过温度调节系统（21）调节半导体器件的温度，该温度调节系统包括用于加热半导体器件的加热器（22），用于检测半导体器件的温度并输出温度的温度检测器（热敏电阻）（17）检测信号（S）;以及控制电路，用于根据温度检测信号控制加热器的致动，以便将半导体器件的温度设定在预定的目标值，该预定的目标值低于假定发生在环境，其中半导体器件位于其中。
主权项	A transmission apparatus using a plastic fiber, comprising: i) a plastic fiber, which is provided with a core containing a polymethyl methacrylate as a principal constituent, and ii) a semiconductor light emitting device, which produces light to be propagated through the plastic fiber, wherein the semiconductor light emitting device is a device, which produces light having wavelengths falling within the range of 630nm to 680nm, and the transmission apparatus further comprises a temperature adjusting system, which comprises: a) heating means for heating the semiconductor light emitting device, b) temperature detecting means for detecting the temperature of the semiconductor light emitting device and feeding out a temperature detection signal, which represents the temperature of the semiconductor light emitting device, and c) a control circuit for controlling actuation of the heating means in accordance with the temperature detection signal, which is received from the temperature detecting means, in order to set the temperature of the semiconductor light emitting device at a predetermined target value that is lower than the highest temperature assumed to occur under an environment, in which the semiconductor light emitting device is located.
