PURPOSE:To lower the possibility of miswiring and suppress, the rise of the temperature. CONSTITUTION:An emergency lamp lighting device 11 is formed on one base board and connected with a commercial AC supply E. A stabilizer 1, emergency lighting circuit 2, and changeover circuit 3 provided in the lighting device 11 are connected by internal wirings. The intra-case wirings with leads are completed only by connections of a battery B and discharge lamp FL with the lighting device 11. This allows deducing the number of leads and facilitating the wiring works. Decrease in the number of leads enables enhancing the draftiness inside of the case body and suppressing the rise of the temperature. |
