A light therapy bed including multiple LEDs positioned in individually controllable modules is disclosed. The modules of LEDs are configured to have direct contact or in close proximity to the skin or tissue of the user, through an acrylic or similar cover. The LEDs light the surface and underlying layers of tissue for photodynamic stimulation of the cells. Iterations of the device utilize light known to have a bactericidal effect in the case of acne, MRSA, etc. The bed is fabricated and formed in a curved configuration to optimize contact between the LEDs and the skin of a user. Each of the LED modules may be mounted on a PCB in an arrangement to provide even lighting and temperature upon the skin or tissue surface of a user. Each module also has one or more thermal sensors that evenly and quickly heat all of the areas of a user's body.
