Red light therapy devices

A red light therapy device comprising:

• a housing with an interior and an exterior, containing within its interior an array of red-light-emitting LEDs and a power supply;
• said housing comprising a bottom surface suitable for stably resting on the surface of a table or floor, and a top surface opposite said bottom surface;
• wherein said top surface comprises a top surface perimeter, and an optical opening with an area greater than three square inches;
• further comprising a red-light-transparent lens with an optical axis and inner and outer surfaces, said outer surface partially protruding out of said optical opening in a direction parallel to the optical axis of said lens and perpendicular to said top surface, where the portion of said lens protruding through said optical opening comprises a convex surface;
• wherein LEDs in said array of LEDs are placed such that said power supply functions to energize said array of LEDs to shine red light through said lens, producing a good-uniformity optical aperture of area at least three square inches coincident with the outer surface of said lens;
• wherein said housing further comprises a first set of at least two removable-stand-attachment features;
• further comprising a detachable stand, said stand comprising a second set of at least two removable-stand-attachment features;
• wherein said first set of removable-stand-attachment features is configured to mate with said second set of removable-stand-attachment features, to removably attach said stand to said housing;
• wherein said first set of removable-stand-attachment features comprises one or more pair of ventilation holes, each said pair of ventilation holes being symmetrically disposed about a plane half way between two parallel side surfaces of said housing.
