Phototherapy devices for treatment of dermatological disorders of the scalp

A phototherapy device for delivering light emissions to a scalp of a patient, the phototherapy device comprising:

• a cap comprising a cap proximal surface and a cap distal surface, the cap proximal surface forming an electronics receptacle;
• a flexible substrate comprising a proximal surface and a distal surface that is opposite the proximal surface, the flexible substate being configured for positioning along the scalp such that the proximal surface is closer to the scalp than the distal surface and the distal surface is closer to the cap proximal surface than the cap distal surface;
• an array of light-emitting devices on the proximal surface;
• a temperature sensor;
• an electronics subassembly on the distal surface, the electronics receptacle configured to receive the electronics subassembly;
• driver circuitry within the electronics subassembly, the driver circuitry configured to drive the array of light-emitting devices and a boost circuit configured to increase voltage to the array of light-emitting devices, the driver circuitry further configured to reduce current to the array of light-emitting devices based on a signal from the temperature sensor, the driver circuitry and the boost circuit being arranged on the distal surface;
• and
• an electronic connection port attached to the electronics receptacle from the cap distal surface, the electronic connection port providing mechanical and electrical connectivity to the driver circuitry.
