Lens frame with a LED support surface and heat dissipating structure

A luminaire with a lens frame for mounting and cooling LEDs, the luminaire comprising:

• a luminaire housing (110) having an opening (112);
• a continuous lens frame (120) extending across and closing said opening (112) of said luminaire housing (110);
• said lens frame (120) comprising a recessed support surface (122) generally facing an illumination direction, a lens retaining area (126) positioned peripherally of said support surface (122) and outward and away from said support surface (122) and said luminaire housing (110);
• a plurality of LEDs (154) coupled to said support surface (122) of said lens frame (120) exteriorly of said luminaire housing (110);
• a lens (188) coupled to said lens retaining area (126);
• wherein said support surface (122), and said lens (128) enclose said LEDs (154);
• and an LED driver (162) located interiorly of said housing (110) remote from said lens frame (120), wherein said support surface (122) having a partially exposed portion to the external environment and said support surface (122) is of a sufficient mass to dissipate heat from an LED board (152).

An LED luminaire, comprising:

• a housing (110) having an opening (112);
• an LED driver (162) surrounded by said housing (110);
• a lens frame (120) contacting said housing (110) and extending completely across said opening (112) of said housing (110), said lens frame (120) comprising a support surface (122), a lens retaining area (126) positioned outward and away from said support surface (122), wherein said lens retaining area (126), and said support surface (122), are all formed as an integral piece;
• an LED board (152) coupled to said support surface (122), said LED board (152) having a plurality of LEDs (154) outputting a directed light output, said LEDs (152) electrically connected to said LED driver (162);
• a lens (188) coupled to said lens retaining area (126);
• wherein said lens (188), and said LED support surface (122), form a chamber enclosing said plurality of LEDs (154);
• wherein said support surface (122) having a partially exposed portion to the external environment and said support surface (122) is of a sufficient mass to dissipate heat from said LED board (152) and wherein said LED driver (162) is mounted within said housing (110) non-adjacent to said lens frame (120).
