COMPACT DISCHARGE LAMP

摘要

Disclosed is a compact discharge lamp capable of preventing the heat from a discharge tube from damaging circuit elements of a stabilizer. The compact discharge lamp includes: the discharge tube having a structure that provides a stabilizer-accommodating space at the center thereof and including an electrode; a bulb base coupled to an end portion of the stabilizer housing; a stabilizer printed circuit board that is accommodated in the stabilizer housing and is provided with stabilizer circuit elements configured to initiate a discharge by being supplied with electric power from the bulb base and by supplying the electric power to the electrode; and a connection space-forming unit that provides a separate connection space near a circumferential surface of the stabilizer housing in order to electrically connect a stabilizer electric power line extending from the stabilizer printed circuit board with the electrode.

1. A compact discharge lamp comprising:
a discharge tube that has a structure providing a stabilizer-accommodating space at the center thereof and that includes an electrode to be supplied with electric power; a stabilizer housing arranged in the stabilizer-accommodating space; a bulb base coupled to an end portion of the stabilizer housing; a stabilizer printed circuit board that is accommodated in the stabilizer housing and that includes stabilizer circuit elements configured to initiate a discharge by being supplied with electric power from the bulb base and by supplying electric power to the electrodes, and configured to perform driving such that the initiated discharge is maintained; and a connection space-forming unit that provides a connection space outside the stabilizer housing and near a circumferential surface of the stabilizer housing so that a stabilizer electric power line extending from the stabilizer printed circuit board is electrically connected with the electrodes therein.
