Therapy light with ventilated led circuit board

A therapy light comprising:

• a housing having a main opening for emitting light therefrom and defining an interior chamber;
• a circuit board having a front face and a back face and operatively mounted within said interior chamber of said housing;
• a plurality of light emitting diodes operatively mounted on said front face of said circuit board so as to face said main opening, for emitting light through said main opening;
• an intake ventilation opening in said housing for permitting said ingress of airflow into said interior chamber of said housing;
• an exhaust ventilation opening in said housing for permitting said egress of airflow heated by said light emitting diodes from said housing;
• a plurality of airflow apertures in said circuit board disposed adjacent said light emitting diodes such that said front face and said back face of said circuit board are in airflow communication one with said other and said intake ventilation opening and said exhaust ventilation opening are interconnected in airflow communication one with said other, wherein the ratio of the cumulative cross-sectional area of the airflow apertures to the cumulative cross-sectional area of the light emitting diodes is greater than about 3:2;
• an airflow generating apparatus having an air inlet disposed in air-receiving relation with respect to said intake ventilation opening and an air outlet disposed in air-delivering relation with respect to said exhaust ventilation opening;
• wherein, in use, said airflow generating apparatus causes air to flow into said intake ventilation opening, from said intake ventilation opening to one of said front face and said back face of said circuit board, through said plurality of airflow apertures to the other one of said front face and said back face of said circuit board, and out of said exhaust ventilation opening, to thereby cool said light emitting diodes.
