Illumination devices for directing light on tissue to induce one or more biological effects, and more particularly activation structures in phototherapeutic illumination devices. Activation structures are integrated within phototherapeutic illumination devices and are configured to avoid electrical activation during shipping and/or between uses. Exemplary activation structures include various integrated sensors, such as accelerometers and proximity sensors. Signals from accelerometers may be used to trigger illumination devices to respond to subsequent signals from proximity sensors for beginning treatment. Accelerometers may be inactive or ignored during shipping until initial device charging.
