<p>The invention discloses an electromagnetic inductive lamp having an improved structure of a lamp tube, which includes a basic structure of the electromagnetic inductive lamp. The lamp tube includes two straight glass tubes which are respectively bridged near the two ends of the two glass tubes to generate "Formula (1)" shape, wherein the ports ~f the two straight glass tubes both protrude. At a port of a straight glass tube of the lamp tube is located an inbuilt exhaust pipe in which an amalgam and an indium grid are put, and in the lamp tube is also located an auxiliary start port in which only an indium grid is put. The invention also discloses an electromagnetic inductive lamp having an improved structure of a lamp tube, which includes a basic structure of the electromagnetic inductive lamp. The lamp tube is double-U tubes, wherein there is a bridge connection between the two U-tubes. On the top ends of the two U-tubes are also located a start port having an inbuilt exhaust pipe in which an indium grid and an amalgam are put, and several auxiliary start ports in which only an indium grid is put. In this invention, the exhaust pipe of the electromagnetic inductive lamp is put inside the lamp tube, so the probability of breaking is decreased. Simultaneity, the lamp tube uses several indium grids as auxiliary start, so the difficulty of starting the lamp tube in the high-power and long-loop electromagnetic inductive lamp is solved.</p> |
