FIELD: electrical engineering.SUBSTANCE: lighting device contains a highlighting unit 12 with cold cathode (CC) lamps 18 positioned inside the inverter board (20) mounting rack and transmissive connectors 21. The inverter boards 20 are placed on the mounting rack 14 side opposed to the CC lamp 18. Each inverter board 20 is intended for supply of excitation voltage to the CC lamps 18. The transmissive connectors 21 are installed on the mounting rack 14 and are intended for transmission of power supply from the inverter boards 20 to the CC lamps 18. Each inverter board 20 is linked to a transmissive connector 21 so that to enable detachment in one direction along the board surface. Installed on the mounting rack 14 side are the interlocking parts 35 and 36 projecting above the basic surface BS in the direction of the inverter board 20 butt-end parts 20e - 20g. Each of the interlocking parts 35 and 36 passes from one edge of the butt-end part 20e, 20f or 20g to the other edge. A gap C is arranged between the basic surface BS and each inverter board 20 that is overlapped by the interlocking parts 35 and 36.EFFECT: reliability improvement.40 cl, 27 dwg |
