PURPOSE:To lowly suppress a temperature rise of each parts by containing separately heating parts for constituting a lighting circuit of a lamp in plural compartment spaces which have been divided independently by a partition wall, respectively. CONSTITUTION:To the side part of a lamp house 2, a frame 3 of narrow width is attached, and in this frame 3, plural pieces of compartment spaces 5 which have been divided independently by plural partition walls 4, and a lamp holding space 6 positioned in these compartment spaces 5 are formed. Also, a transformer 13 and a transistor 14 are positioned independently in the compartment spaces 5, and even if they are brought to temperature rise, no thermal synergetic effect is generated. In such a way, a temperature rise of each parts is suppressed lowly, and the reliability can be improved. |
