摘要:
Provided is a lighting apparatus that includes a housing having a bottom surface, a first side surface that extends from the bottom surface and a second side surface that extends from the bottom surface and positioned to face the first side surface. A substrate having a plurality of LEDs may be provided. A diffuser may be removably coupled to the housing and positioned over the substrate. An electronic module may be provided in the housing. The housing may include a first channel formed on the first side surface of the housing and a second channel formed on the second side surface of the housing. The first and second channels may be positioned to face each other to accommodate the diffuser. Moreover, at least one opening may be formed at the first and second channels for slidably inserting the diffuser in the first and second channels.

摘要:
Provided are a method of preparing a transparent copolymer resin by continuous bulk polymerization of a polymerization mixture obtained by adding a phenol-based antioxidant and/or a phosphate-based antioxidant, a chain transfer agent, and an organic peroxide initiator to a monomer mixture including a styrene monomer, an acrylate monomer, and an acrylonitrile monomer, and a transparent copolymer resin prepared by the method, having good chemical resistance, fluidity, and discoloration resistance.
