Description
また図5(B)のものは拡散部材内面で乱反射が生じ透光量が少なくなるほか、カバー内面に拡散部材を貼付け又はその他の方法で、しかも耐熱条件下で固定する必要がある。
また従来のLED光拡散技術のようにカバー側に凹レンズ状の突起を設ける必要もなく、カバー内面に拡散板を介挿する必要もない他、透明カバーを用いた時は最大限の光量で近距離範囲を照射できる利点がある。

Claims (5)
- 基板(2)の表面側の空間に多数のLED(1)を突設し、該LED(1)の表面側を透光性のカバー(3)で覆う集合型ランプにおいて、上記カバー(3)をその内面でLED(1)の突出端を密着状態で埋入させ、LED(1)の先端周面の一部と一体的に密着するようにモールド成形するとともに、基板(2)とカバー(3)の内面との間に空間を形成し、該カバー(3)断面内でLED(1)の光を表面側に拡散させる集合拡散型LEDランプ。
- カバー(3)の内面側の一部又は全部をプラスチック材をモールドすることにより形成した請求項1の集合拡散型LEDランプ。
- カバー(3)を予め板状又は皿状に成形し、基板(2)側に直接又は間接的に固定される外カバー(3a)と、外カバー(3a)の内面側でモールドによって成形され、LED(1)の突出端を埋入させる内カバー(3b)とで構成する請求項1又は2の集合拡散型LEDランプ。
- カバー(3)の少なくとも正面側が均一な厚みに形成され、LED(1)がカバー(3)の肉厚内に埋入された請求項1又は2又は3の集合拡散型LEDランプ。
- カバー(3)が透明なプラスチック材よりなる請求項1又は2又は3又は4の集合拡散型LEDランプ。
