<p>A lighting device using fluorescent lamps, comprising fluorescent lamps (1) each having a translucent airtight container (1a), a discharging medium formed mainly of a rare gas sealed in the translucent airtight container (1a), and at least a pair of electrodes (1b) and (1e) producing a discharge inside the translucent airtight container (1a), reflection means (2) disposed near the fluorescent lamps (1), and translucent resin (3) provided between the fluorescent lamps (1) and the reflection means (2) in contact therewith, wherein the translucent resin (3) transmits the heat generated from the fluorescent lamps (1) to the reflection means (2) to improve the diffusion of the heat, whereby the lowering of a light emitting efficiency can be suppressed by promoting the diffusion of the heat from a rare gas discharge lamp.</p> |
