摘要： A flood lamp having a lens with a series of concentrically disposed fluted rings on the internal lens surface in combination with an outer concentric ring adjacent to and wider than any one of the fluted rings and containing a plurality of semi-spherical protrusions disposed in an established pattern (e.g., circular or hexagonal). The flood lamp reflector has multiple reflective surfaces including a front section that is parabolic shape having a principle focal point, a spherical section having its center of radius coincident with the principle focal point of the parabolic front section, and a spherical rear section.

摘要： A spot lamp having a lens with a series of concentrically disposed fluted rings on the internal lens surface in combination with an outer concentric ring adjacent to and wider than any one of the fluted rings and having a stippled surface. The spot lamp reflector has multiple reflective surfaces including a front section that is parabolic shape having a principle focal point, a spherical section having its center of radius coincident with the principle focal point of the parabolic front section, and a spherical rear section.
摘要翻译： 一种具有在内透镜表面上具有一系列同心布置的带槽环的透镜的聚光灯，其与与所述任何一个凹槽环相邻并且宽于所述凹槽环的外部同心圆组合并且具有刻点表面。 点灯反射器具有多个反射面，该反射面包括具有原理焦点的抛物面形状的正面部分，具有与抛物面前部分的原理焦点重合的半径中心的球形部分和球形后部分。

摘要： A spot lamp having a lens in the form of a curved member having an inner surface with a series of radially disposed flutes formed therein defining a fluted portion which surrounds a centrally disposed stippled portion. The flutes each extend linearly from a position adjacent the stippled portion outwardly to a position adjacent the outer edge of the curved member. The surfaces of the flutes are also stippled.
