Abstract
A fluorescent lamp has an amalgam chamber that is in communication with the interior of the lamp through an exhaust tube. The amalgam chamber is constructed as a three-way junction with the exhaust tube and is formed at a supplementary angle of 180 degree or less with respect to the exhaust tube. The construction of the chamber utilizes the force of gravity to keep the amalgam away from the opening of the exhaust tube leading to the interior of the lamp. The amalgam chamber is capable of effectively retaining the amalgam within the chamber and preventing it from penetrating into the interior of the lamp regardless of mounting direction.
Claims8
A fluorescent lamp comprising:
- a) a glass tube sealed in a vacuum tight manner and contain a mixture of inert gas and mercury vapor,
- b) at least one induction coil wrapped around a portion of the tube,
- c) at least one exhaust tube having an amalgam chamber containing an amalgam, wherein said amalgam is retained within the chamber regardless of the lamp mounting direction.
An amalgam chamber for a fluorescent lamp, said chamber containing an amalgam and provided with an opening that is in communication with the interior of the lamp through an exhaust tube, said chamber is constructed to form a three-way junction with said exhaust tube and is formed at a supplementary angle of 180 degree or less with respect to said exhaust tube, wherein said chamber is capable of retaining the amalgam within the chamber and preventing it from penetrating into the interior of the lamp regardless of the lamp mounting direction.
