and (4□) are formed and mercury reservoirs (51) and (5□) are arranged to arrange mercury (6) around electrodes (3I) and (3□).
) is provided. The inner ends (tips) of the discharge electrodes (31) and (3□) are configured to protrude from the mercury reservoirs (51) and (5□), that is, from the mercury (6).

害うという不都合を生じることになることに因る。When this mercury lamp is lit in a horizontal position, the mercury (6) at both ends tends to move, so when placing this mercury lamp vertically or diagonally, it is important to The gravity of the mercury makes it easier to move, causing short circuits between electrodes (3,) and (3□), and preventing stable lighting when the mercury lamp is turned off and then turned on again. It depends on what is going to happen.

Due to repeated evaporation and condensation of mercury in 1), bubbles from the rare gas sealed in the discharge space enter the mercury reservoirs (5,) and (5□), and these bubbles enter the mercury reservoirs (51).
and (52), and eventually, when the mercury lamp is turned off, the mercury (6) is transferred to the mercury reservoir (5,
) and (52) cause so-called mercury to be pushed out into the discharge space (2), and as a result, it takes a considerable amount of time for the discharge to reach a steady state at the next lighting. At low pressure until this steady state is reached, the electrode (3I) made of tungsten W, for example.
The tip of (3□) becomes red hot and a spanter phenomenon occurs in which constituent materials such as W atoms fly out, indicating a decrease in life.

、その寿命は、従前の約２倍の長寿命化がはかられた。According to the above-mentioned configuration, since both ends of the ultra-high pressure mercury lamp are tilted from the horizontal by the required angle θ, evaporation and condensation of mercury due to repeated turning on and off of the mercury lamp M can be prevented. This makes it difficult for air bubbles to enter the mercury reservoirs (25υ and (25□)), and
+ ) and (25□), these bubbles are likely to be drawn upwards, that is, out of the mercury reservoirs (25,) and (25□).
Bubbles grow in the discharge space (2) and transport mercury (6) into the discharge space (2
2) It is possible to avoid mercury being pushed out or spouted out. Therefore, the inconvenience that it takes a long time for the discharge to reach a stable state during lighting is avoided, and the inconvenience that spatter occurs due to the discharge electrode being in a red-hot state for a long time under low pressure is also avoided. As a result, its lifespan has been extended to about twice that of the previous model.
また、発光状態が安定化されることによって光量制御を
容易かつ正確に行うことができる。Further, by stabilizing the light emission state, the light amount can be controlled easily and accurately.

場合に比し、配光分布もとり易いという利点がある。In addition, when the tube extends in a straight line as in the past, external circuits must be connected to the picture electrode terminals individually, and unnecessary force is applied to the tube at the time of connection, which can lead to damage. However, in the present invention,
Since the tubular body (21) is bent, the terminals of both electrodes can be led out from the common base (28) as shown in FIG. (28) mechanically integrates both ends of the tube body (1), thereby producing a reinforcing effect and drastically reducing the possibility of breakage of the tube body (21). In addition, the overall size and compactness can be achieved. Furthermore, compared to the case where the mercury lamp is linear, there is an advantage that the light distribution is easier to obtain.
