Inventor: AKIYAMA KAZUO
IPC: F21V5/00
Filed: 2000-02-29
Abstract: PROBLEM TO BE SOLVED: To improve an appearance quality of a surrounding part of a bonding surface of a front lens and a lamp body and to improve bonding strength sufficiently. SOLUTION: The appearance quality of the surrounding part of the bonding surface is improved by laser-welding a tip surface 16d of a seal leg 16a formed on the front lens 16 and a receiving surface 14b formed on the lamp body 14 as the bonding surface. The tip surface 16d is formed on a tip part 16c of the seal leg 16a extending to an outer periphery side against a bonding direction in such a manner of bending with designated angles. Laser beam is applied on the receiving surface 14b from a direction almost orthogonal to the tip surface 16d through the tip part 16c. A transmission distance, thereby, is greatly reduced comparing to the case of applying laser beam through a clear press down plate 104 and the seal leg 16a, and a sufficient irradiation energy is secured.  The tip surface 16d and the receiving surface 14b are contacted with a uniform pressure in a width direction by pressing the front lens 16 at a base part of the seal leg 16a. A required bonding strength over the width of the bonding surface, thereby, can be easily secured.
