A fluorescent lamp uses new cold-end technology or an enveloped fluorescent lamp with high surface load. The lamp features a lamp tube, cathode, stem cap and wire, such that one end of the wire connected to the cathode is fixed on the stem cap and the other end of the wire is led out from the lamp tube. At least one cavity tube connecting through the lamp tube is disposed on the side of at least one lamp tube. Advantages of the fluorescent lamp include: (1) the temperature of cavity tube is not influenced directly with electrical arc since there is no discharge through appended cavity tube, thus mercury-vapor pressure adjustment with cold-end is made possible; furthermore, mercury-vapor pressure is decreased significantly on energy saving lamps with high power or lamps in high environmental temperature; (2) by adjusting the length and/or position of the cavity tube, mercury-vapor pressure in the lamp tube can be adjusted efficiently; (3) if amalgam is required for the lamp tube, the adjustment work becomes easy and efficient by positioning the amalgam at the coldest point; with adding auxiliary cathode selectively, good luminous flux is formed rapidly when the lamp is turned on initially; (4) the effective service life of the lamp tube is lengthened since the harmful materials to luminous flux output produced during lamp operation are collected at the cold-end of cavity tube.

The present invention discloses a lamp tube of a covered bulb, including a lamp body and a core column, with a filament and an exhaust pipe on the core column, characterized in that the exhaust pipe has a bent shape. The lamp tube of the covered bulb of the present invention can reduce the working temperature of the amalgam, and increase the difference between melting temperature and working temperature of the amalgam. Besides, it can also avoid the flow of the melted amalgam when the lamp is on for a long time. It is important that the lamp tube of the covered bulb for the invention can ensure that the amalgam is at the optimum working temperature, the saturated mercury vapor pressure reaches the optimum state, whereby the consistence of photo-electricity parameter will be considerably increased. It can increase the luminous flux maintaining rate for the whole lamp to prolong the service life of the lamp, because the lamp tube of the covered bulb of the invention is often placed downward during use. The amalgam cannot flow towards the lamp tube after it melts. The structure of the exhaust pipe of the lamp will limit the flow of the amalgam. The operation is simple during assembling, easy to learn and the cost is low.

A metal halide lamp (101) is described, the lamp being designed such that, when the lamp is operative in a vertical orientation, the location of the salt pool is close to the top of the discharge chamber (5). In an embodiment, the coldest spot is close to the top of the discharge chamber. Means are provided enabling more heat to be supplied to the bottom part than to the upper part. In a lamp assembly (10), comprising a lamp (101) arranged inside a bulb (11), additional heat generating means (90) may comprise a radiation coil (91).

A vacuum device, including a substrate and a support structure having a support perimeter, where the support structure is disposed over the substrate. In addition, the vacuum device also includes a non-evaporable getter layer having an exposed surface area. The non-evaporable getter layer is disposed over the support structure, and extends beyond the support perimeter, in at least one direction, of the support structure forming a vacuum gap between the substrate and the non-evaporable getter layer increasing the exposed surface area.

Low-pressure mercury vapor discharge lamp comprises a light-transmitting discharge vessel (10) enclosing, in a gastight manner, a discharge space (13) provided with a filling of mercury and a rame gas. The discharge vessel comprises discharge means (20a; 20b) for maintaining a discharge in the discharge space. The discharge vessel is provided with a container comprising an amalgam (2). The container is provided with releasing means (4) for the controlled release of mercury vapor from the amalgam. The releasing means is open during lamp operation and is substantially closed when, during lamp operation, the temperature of the amalgam becomes higher than a pre-determined temperature. Preferably, the predetermined temperature corresponds to a temperature of a range of temperatures at which the mercury-vapor pressure above the amalgam is relatively stable.

The display panel includes a gas-filled envelope made up of a base plate and a face plate hermetically sealed together. A cell sheet is disposed between the base plate and face plate, an array of cathode strips is disposed between the base plate and cell sheet, and an array of anodes is disposed between the face plate and cell sheet, with the anodes being disposed at an angle to the cathodes so that each crossing of an anode and cathode and the volume of gas between them define a display cell. The cell sheet includes slots which define rows of separate operating areas on each cathode. In addition, each cathode strip defines a column of operating cathode areas. The panel carries a mercury capsule, whether in the tubulation or in a convenient portion of the cell sheet, and the cell sheet is provided with channels or slots, in communication with the mercury capsule, to facilitate the dispersion of mercury throughout the panel.
