Connected to the power cable 12. Heater power is supplied to the heater power cable 12 from a power supply device (not shown). The heater feed cable gland 11 is used to insert a heater power cable 12 for supplying heater power in parallel to the heater of the adjacent appliance when an equivalent outdoor lighting fixture is connected in series.

透明ヒータ６は、電熱抵抗線を有していない厚さ１００μｍ程度の薄いフィルムヒータである。このヒータの抵抗値は、略２００Ωであり、ＡＣ又はＤＣ４８Ｖを印加して２０℃乃至３０℃となる。また、ヒータ電源の供給回路には、サーモスイッチ等を組み込んで、器具内の温度が高くなりすぎないように制御することが好ましい。また、器具が使用される外気温に応じて、ヒータ通電をオン／オフできるようにする。   The transparent heater 6 is a thin film heater having a thickness of about 100 μm that does not have an electric resistance wire. The resistance value of the heater is approximately 200Ω, and is 20 ° C. to 30 ° C. when AC or DC 48V is applied. Moreover, it is preferable to incorporate a thermoswitch or the like in the heater power supply circuit so that the temperature inside the appliance does not become too high.
