"×" is labeled as during less than 2000lm (lumen).
In the evaluation of the expansion to illuminating part 11, size of the illuminating part 11 on the direction orthogonal with the axial direction of inner tube 1
Change is labeled as "○" when turning to less than 28%, and "×" is labeled as when the change in size of illuminating part 11 is more than 28%.
Also, in overall merit, if in the evaluation of the evaluation of total light flux and the expansion to illuminating part 11 at least
One side is "×", then overall merit is labeled as "×", if the evaluation of the evaluation of total light flux and the expansion to illuminating part 11 is equal
For "○", then overall merit is labeled as "○".
As can be known from Table 1, if inclosure pressure P of the inert gas under normal temperature (25 DEG C) and illuminating part 11 thickest t
The ratio between meet following formula, then can suppress the expansion of illuminating part 11, and can obtain being used as total light required during high beam
Flux.
That is, can be obtained by simple structure can realize the discharge lamp 100 of dipped headlight and high beam.
7.2(atm/mm)≤P/t(atm/mm)≤10.0(atm/mm)
The electrical power applied in addition, in table 1, during as dipped headlight is set to 27W, the electrical power applied during as high beam
It is set to 34W.But the electrical power applied when will act as dipped headlight is set to more than 24W and below 30W, will act as applying during high beam
The electrical power added is set to more than 32W and below 38W, can also obtain identical effect.

From proper range.Now, the too high or too low for temperature of electrode 32 can cause arc spot unstable, therefore can produce flicker.
If produce flicker, can to driver or other people bring sense of discomfort.
According to the opinion of the present inventor, if distance (interelectrode distance) L1 between the front end of a pair of electrodes 32 is set
To meet equation below, then the stabilisation of arc spot can be realized, therefore can suppress to produce flicker.
3.0(mm)≤L1(mm)≤3.6(mm)
