Abstract:
A ceramic metal halide lamp, which relates to the technical field of bulbs and comprises a lamp cap (1), a glass outer cover (2), an inner tube (3) and a ceramic metal halide arc tube (4), wherein the inner tube (3) is fixed with a first bracket (51), one end of the ceramic metal halide arc tube (4) is fixed in the inner tube (3) through the first bracket (51), and one end of the ceramic metal halide arc tube (4) is sleeved with a fixing ring (61) comprising one or more continuous bends, and the fixing ring (61) is connected to the first bracket (3); the first bracket (3) is in communication with the lamp cap (1); and the first bracket (3) and the fixing ring (61) are made of the same material. The fixing ring (61) not only can avoid the ionization effect, but also make the ignition voltage output by a ballast generate an induced voltage on the fixing ring when the bulb is started, which makes the bulb easier to start and greatly reduces the starting voltage of the bulb.
