Abstract

PROBLEM TO BE SOLVED: To improve heat conversion efficiency, secure safety, and miniaturizing and lightening an infrared heater by generating infrared rays directly from electricity instead of such a process of converting electricity to heat and converting the heat to infrared rays and by solving such problem that various types of infrared heater have been manufactured and sold, but many types of heater are of heating ceramics or the like at a high temperature and involving dangers such as burns, and due to the large scale structure for heating ceramics, they cannot be miniaturized or lightened with ease. SOLUTION: The constitution of the infrared heater relating this invention 1 comprises an infrared panel section comprising a plurality of infrared LEDs arranged on the same surface of the panel, and a power supply section for supplying power to the infrared LEDs. This constitution allows the direct conversion of infrared rays from electricity, resulting in the improvement of conversion efficiency. The arrangement of a plurality of infrared LEDs on the same surface of the panel makes it possible to radiate quantity of infrared rays required for heating to the space or the object to be heated by infrared rays.

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a heating device for heating a room or a human body by irradiating infrared rays.

[0002]

2. Description of the Related Art Infrared heating devices have been manufactured and sold in various forms since the past. However, many of them are in the form of emitting infrared rays by heating ceramics to a high temperature, and there was a risk of burns. Further, since the structure for heating the ceramic is large-scaled, it is difficult to reduce the size and weight.

[0003]

In view of the above situation, the present invention generates infrared rays directly from electricity in the process of converting infrared rays from electricity to heat and heat to infrared rays, thereby improving conversion efficiency and safety. The purpose is to secure the characteristics and to reduce the size and weight.

[0004]

In the infrared heating device of the present invention 1, an infrared panel section having a plurality of infrared LEDs arranged on the same plane, and a power supply section for supplying power to the infrared LEDs are provided. An infrared heating device characterized by the above.

With this configuration, it is possible to directly convert electricity into infrared rays, and the conversion efficiency is improved.
Further, by disposing a plurality of infrared LEDs on the same surface, it was possible to irradiate a space or an object to be heated with an amount of infrared rays necessary for heating.

In the infrared heating device of the second aspect of the present invention, the infrared panel has a configuration in which a plurality of warm color LEDs for visible light are mixedly formed.

With this structure, the invisible irradiation of infrared rays can be visually confirmed, and the warm color LED is used.
Can perceive the image of being warm.

In the infrared heating device of the third aspect of the present invention, a configuration is adopted in which a lens for diffusion and convergence is arranged on the front surface of the infrared panel.

With this structure, it is possible to make the room temperature uniform by diffusing infrared rays, and when converged, it becomes possible to locally concentrate and heat.

BEST MODE FOR CARRYING OUT THE INVENTION In order to more specifically show the present invention,
Some examples are given below with reference to the accompanying figures.

[0011]

[Embodiment 1] This embodiment will be described with reference to FIG.
Infrared LED for direct current supplied from power supply (1)
An infrared panel section (5) was constructed which emits light by energizing the conductive material (4) of the film-like substrate (3) connected to (2).

In this embodiment, 10 sets of infrared LEDs are connected and 5 sets are connected. However, the connection configuration can be arbitrarily changed depending on the power source, and the number of infrared LEDs can be simply increased. As a result, a desired heating effect can be obtained. In particular, since the amount of heat generated by the LED itself is small, there is no danger of being burned or the like even if it comes into direct contact with the skin for a short time, and if the infrared panel section (5) is covered with a cloth or the like, it becomes a contact type infrared heater.

Further, the power supply device may be composed of a portable power supply such as a dry battery, and if so configured, it can be used outdoors as a portable heater.

[0014]

[Embodiment 2] In Embodiment 1, all are infrared LEDs (2)
Although the infrared panel section (5) was constructed with, a part was replaced with a warm color visible light LED.

Visible light LED (2A) and infrared LED (2)
Although the composition ratio of is changed depending on the application, it is desirable that the composition ratio of the visible light LED does not exceed 50%. With this configuration, the heating effect can be perceived perceptually.

[0016]

[Embodiment 3] In Embodiments 1 and 2, the infrared rays are radiated linearly from the infrared panel section. However, in the present Example, the convex lens (6) is arranged in front of the infrared panel section (5) and the infrared rays are emitted. Is refracted and converged to centrally heat the local area.

With such a structure, it is possible to locally heat the hands, feet, etc., and when using a face pack or the like, by irradiating infrared rays to the face-packed portion, the heating effect is further enhanced, and further The effect of can be obtained.

[0018]

According to the present invention, electricity is directly converted into infrared rays to improve efficiency, and efficient, compact and lightweight infrared heating is realized.
