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.Field of SearchJoining of nonplanar elements; e.g., configured hollow objects, etc.With preliminary edge treatment or joining of edges of irregular shape; e.g., tongue and groove, beveled, etc. Of laminae having opposed facing areas out of contact With encapsulating of permanently fluent material in hollow or porous lamina or filling of space between adhered laminae Prior to bonding of laminae (e.g., golf balls) Subsequent to assembly of laminae Providing escapeways for gases trapped or generated between layers Particular adhesive Optically transparent glass sandwich making (e.g., window or filter) Mounting transparent lamina over window opening (e.g., slide-mounting) Multipane glazing unit making (e.g., air-spaced panes) Pore forming Aluminum compound containing, e.g., zeolites, perlite, etc. Expanding, foaming or porosity producing additive Mica, elemental carbon, zeolite or talc containing With hermetic seal With sealing means or artifical atmosphere Enclosed light source Enclosure type Humidity or temperature control Sealing TRANSPARENT PANEL HAVING ACTIVE TREATMENT WITH GAS OR LIQUID LIGHT TRANSMISSIVE SHEETS, WITH GAS SPACE THEREBETWEEN AND EDGE SEALED (E.G., DOUBLE GLAZED STORM WINDOW, ETC.)
