A heating system includes a sensing and tracking module to sense length in at least one dimension of an object to-be-heated in a previously determined area. A light source module has at least one light source that can change its lighting direction and can also change its beam angle e along the at least one dimension. A control module is provided for regulating light emitted by the light source module onto the to-be heated object along the at least one dimension to match with the length of the to-be-heated object based on the length sensed by the sensing and tracking module. The heating system described above and a bed incorporated having this kind of heating system may automatically adjust its output power according to the physical characteristics of the object to-be-heated to avoid heating unrelated object, area or space so as to ensure high energy efficiency.

This control comprises at least one frequency converter having a first, a second and a third output so that between the first and the third output a first alternating current is providable and between the second and the third output a second alternating current is providable by means of which the at least one radiation source is operable.

A mat using infrared LEDs comprising an infrared LED aluminum package (3), a temperature controller (2) supplying a power supply to an infrared LED chip (13), a FPCB (flexible printed circuit board) having the infrared LED aluminum package (3) mounted therein and including a terminal connecting the infrared LED aluminum package (3) to a wire, and a base sheet (6) for dispersing heat. According to the mat using infrared LEDs, aluminum with high thermal conductivity better radiates heat, the infrared light emitted from the LED is helpful for treatment and health improvement, the thin thickness of the infrared LED aluminum package prevents discomfort when a user lies thereon and the mat which is light in weight is easily movable or rollable for storage.

A method for controlling a toilet air heating device includes: in response to a start instruction, controlling an air heating wire component to heat, controlling an air heating fan to blow air, controlling a drive motor to drive an internal air duct to extend out along an extension direction of an external air duct, and controlling an auxiliary heater to heat, wherein an air heating wire component controller controls the air heating wire component while a master controller controls the air heating fan, the drive motor, and the auxiliary heater.

A heating element can be moved by a machine, such as a machine including a fan, an actuator, or a conveyor. The heating element can be attached to or embedded in a fan or an actuator. Or, the heating element can be attached to or embedded in a conveyor belt of a conveyor. A combination of a heating element and a mover machine can be further combined with a heat radiating wall. The heating element and the machine can be arranged behind the wall. And, when the heating element and the machine are powered on, the heating element converts electrical energy into heat, which increases the temperature of the wall, and the machine moves the heating element to be next to different areas of the wall. This allows for heat to be distributed more evenly to the wall than it would be if the heating element did not move.

A fabric warming rack comprising at least one rod extending along a horizontal plane with one or more light sources integrated into the at least one rod.
