Mat and blanket by means of near-infrared LED

Abstract

The invention discloses a mat by means of near-infrared LED. The mat comprises the components of an LED light emitting layer of which one surface is provided with a flexible printed circuit board withat least one LED; an insulating layer which is coated to one surface of the LED light emitting layer for protecting the LED light emitting layer and has a larger thickness at the corresponding position which is equipped with the LED than the corresponding position that is not equipped with the LED; a board layer which accommodates and fixes the LED light emitting layer and the insulating layer; and a porous covering layer which covers the board layer and is made of a porous material so that light which is transmitted from the LED can pass through.

Description

technical field [0001] The present invention relates to a mat and a blanket utilizing near-infrared light-emitting diodes, and more particularly to a mat and a blanket. The light transmitted by the human body and the heat transmitted. Background technique [0002] Generally, the electric heating pad uses nickel-chromium alloy wire, carbon fiber, and sheet heating element. However, the problem is that if the above-mentioned resistance element is used, when a heavy object is placed on the mat or a folded part of the mat occurs, there is a risk of overcurrent due to an increase in temperature of the corresponding part, and a fire due to abnormal heating. Danger. [0003] In addition, near-infrared rays are light with a wavelength of 700nm to 10um and below. Near-infrared light-emitting diodes are about 200nm in the standard range of their spectrum (spectrum), and light with a wavelength of about 700-850nm emits part of red light, so that it can display parts. Red light, but ...

Problems solved by technology

[0004] When using a heating pad using far-infrared light-emitting diodes, the human body's heat-retaining effect is excellent, but if the wavelength of far-infrared rays becomes longer, it is used as a function of cooking meat similar to microwaves, so the problem is that, affect the human body

[0005] The problem is that even with a heating pad utilizing LEDs, when the pad is folded or bent, the electrical connection of the element is interrupted, and overcurrent and abnormal heating occur

[0006] In addition, in the case of electric blankets, there is a problem in that the body is moved while the person is covered with the blanket, so when the power supply is connected through a connector, there is a limit to the mobility and the connector is separated during the movement
