<p>PURPOSE:To reduce the radiation of the heat of a soldering iron to shorten a soldering work time and improve reliability by applying folding or slit to a lamp holder to provide the solder land of the lead wire or the electric wire of a discharge tube. CONSTITUTION:In a back light, a discharge tube is located on at least one side surface of a transparent light-leading body 3 surrounded by a lamp holder 2 wherein an inner side is covered by a light reflecting layer to locate a light diffusion plate 6 in one side surface of the light leading body 3. At the time of the stamping of the holder 2, a slit is formed on e.g. the periphery of the soldering place of a returning electric wire 5 to adopt a range surrounded by the slit as solder land 8. This can reduce the heat radiation of a soldering iron to shorten a soldering work time required for 5 seconds so far down to 2 seconds or less.</p> |
