[0114]In Table 1 below, 1A-1D denote lamps (luminescent tubes L) containing substances exhibiting relatively high radiant power (output) in the near-infrared region (750-1100 nm). In each luminous tube L, rated at 35 watts, the entire length of the airtight bulb including the sealing portions 12 at both ends is about 50 mm, with a portion of the largest diameter of the substantially ellipsoidal cavity 11 inflated in the middle. The outer and inner diameters are about 6 mm and about 2.7 mm, respectively, the inner volume of the chamber 11 is about 0.05 cubic centimeter, and the pair of discharge electrodes 3 are opposed to each other at a distance of about 4 mm.
[0115] In addition, the cavity 11 of the luminous tube L (1A-1D) was filled with the substances shown in Table 1 and did not contain mercury. Table 1 illustrates the radiant power output (W) and power ratio V / R of each LED L (1A-1D) in the visible region V (380-780 nm) and near-infrared region R (750-1100 nm). 1H in ...

[0122] In Table 2 below, 2A-2G represent lamps (luminescent tubes) containing materials that exhibit almost the same radiant power (output) between the visible region (380-780 nm) and the near-infrared region (750-1100 nm). L). These lamps are suitable both as light sources for headlights and as infrared light sources for infrared detection devices, as will be explained below.
[0123] In each luminous tube L, the rated power (input) is 40 watts, the entire length of the airtight bulb including the sealing parts 12 at both ends is about 50 mm, and the maximum diameter of the substantially ellipsoidal cavity 11 with the middle part expanded The outer and inner diameters of the diameter portion are about 6 mm and about 2.7 mm, respectively, the inner volume of the cavity 11 is about 0.05 cm3, and the pair of discharge electrodes 3 are opposed to each other at a distance of about 4 mm.
[0124] In addition, the cavities 11 of the luminous tubes L (2A-2G) were sealed with the sub...
