Summary:PROBLEM TO BE SOLVED: To provide a glass lid capable of efficiently condensing light in the horizontal direction of a DUV (deep ultraviolet)-LED element forward, and an LED device using the glass lid.SOLUTION: An inner circumferential wall includes: a DUV light transmissive glass frame 11 having an inclined wall also serving as a reflector base portion; and a DUV light transmissive glass window 12 airtightly sealed to the frame so as to cover one opening of the frame. The frame has at least a DUV reflective coating 13 on an inclined wall surface 11a.SELECTED DRAWING: Figure 1 【課題】ＤＵＶ（深紫外）−ＬＥＤ素子の水平方向の光を効率よく前方に集光させることができるガラスリッド、およびそのガラスリッドを利用したＬＥＤ装置を提供する。【解決手段】内周壁面が、リフレクタ基部を兼ねた傾斜壁を有するＤＵＶ光透過性ガラスの枠体１１と、この枠体の片方の開口を覆って枠体に気密封着したＤＵＶ光透過性ガラスのウインド１２とを備え、枠体は少なくともその傾斜壁面１１ａにＤＵＶ反射性被覆１３を有する。【選択図】図１
