Title (EN) GLASS SUBSTRATE WITH LIGHT DIRECTIVITY AND ILLUMINATOR EMPLOYING THE SAME
(FR) SUBSTRAT DE VERRE AVEC DIRECTIVITÉ DE LUMIÈRE ET SYSTÈME D’ÉCLAIRAGE EMPLOYANT LEDIT SUBSTRAT
(JA) 光線指向性化ガラス基板及びそれを用いた照明装置
Abstract: front page image
(EN)A high-precision flat illuminator which has sufficient evenness of luminance and sufficient directivity with respect to light progress. It can be produced by an easy process. A paste comprising at least one member selected from the group consisting of lithium compounds, sodium compounds, potassium compounds, rubidium compounds, cesium compounds, copper compounds, silver compounds, and thallium compounds, an organic resin, and an organic solvent is applied to one or both sides of a glass substrate containing an alkali metal ingredient as a glass component. The coated glass substrate is heated at a temperature lower than the softening temperature of the glass substrate. Thus, the glass substrate having light directivity is produced. The flat illuminator employs the glass substrate.
(FR)L’invention concerne un système d’éclairage plat haute précision d’une luminance suffisamment uniforme et de directivité suffisante par rapport à la progression de la lumière. On peut l’obtenir grâce à un simple processus. Elle divulgue une pâte comprenant au moins un élément sélectionné parmi le groupe consistant en composés de lithium, composés de sodium, composés de potassium, composés de rubidium, composés de césium, composés de cuivre, composés d’argent et composés de thallium, une résine organique, et un solvant organique est appliqué à un côté ou bien aux deux côtés d’un substrat de verre contenant un ingrédient de métal alcalin comme composant de verre. Le substrat de verre revêtu est chauffé à une température inférieure à la température de ramollissement du substrat de verre. Ainsi, on obtient le substrat de verre ayant une directivité de la lumière. Le système d’éclairage plat emploie le substrat de verre.
(JA) 本発明は、均一な輝度と光線の進行方向の指向性とが十分に確保された、高精度な平面光源を簡便な作製方法により提供する。  具体的には、アルカリ金属成分をガラス構成成分として含むガラス基板の片面又は両面に、リチウム化合物、ナトリウム化合物、カリウム化合物、ルビジウム化合物、セシウム化合物、銅化合物、銀化合物及びタリウム化合物からなる群から選択された少なくとも1種、有機樹脂並びに有機溶剤を含有するペーストを塗布し、ガラス基板の軟化温度より低い温度で熱処理することによって製造される、光線指向性化ガラス基板及びそれを用いた平面光源を提供する。
