Abstract

PURPOSE: To prevent deterioration, by improving the ultraviolet rays resistivity and thermal resistance of adhesives, which components are thermal hardening resin and silicon resin, by sticking a bulb and a base by using said adhesives.
CONSTITUTION: As adhesives 11 in the case when mounting a base 6 to a bulb 1, matter is used which thermal hardening resin such as phenol resin, said hardener, silicon resin, said hardener, resin, such as, rosin, shellac, etc., calcium carbonate powder, an ultraviolet rays absorbent and a solvent are mixed adjusted at appropriate rate. The matter is put between a sealing bulb 1 of the bulb and the base 6, heating hardened at 200W250°C and for approximate 3W5 minutes and sticked. The adhesives 7 have strong adhesive strength, the silicon resin slightly deteriorates due to ultraviolet rays and heat, and the silicon resin protects the thermal hardening resin and the natural resin from ultraviolet rays, thus harldy lowering adhesive strength to the lighting of a lamp for a long term, then preventing the falling-off of the base 6.
