AbstractA lighting fixture body and a lens, both formed of plastic which generates gas when heated, are bonded together, using a hot melt adhesive with adsorbent mixed therein, thereby preventing foams from residing in the interface between the plastic materials and the hot melt adhesive. The hot melt adhesive is mainly composed of styrene-ethylene-butylene block copolymer, and molecular sieve or other adsorbent having adsorbing cavities is added to the hot melt adhesive. After the hot melt adhesive is filled in the sealing grooves of the lighting fixture body, the anchoring parts of the lens are set in the hot melt adhesive and fastened mechanically with spring pegs. The hot melt adhesive solidifies in the sealing grooves, thereby fixing the lighting fixture body and the lens together.
