Description

  The present invention relates to a radiant heating apparatus using an incandescent bulb such as a halogen lamp that emits infrared light and visible light as a light source.

Conventionally, as shown in FIG. 4, an infrared radiation lamp composed of a halogen incandescent bulb 1 and a reflecting mirror 2 is used in a radiant heating apparatus using this type of halogen lamp. When used, for example, a person who is the object of radiation is irradiated with a radiation beam in a spot manner to obtain a feeling of heating. For this reason, it has been performed exclusively by providing a plurality of lamps in a narrow space. (For example, refer to Patent Document 1).
JP-A-7-332683

  However, in the above-described conventional configuration, since the radiant heat ray is irradiated in a spot manner, the energy obtained by the radiant lamp is at most equivalent to the electric input of the lamp, and when applied to a large-scale air conditioning system, The efficiency was low and it was contrary to energy saving, and had the subject that it was not practical.

  Moreover, in such a conventional system, the radiant heat ray is fixed according to the installation angle of the reflecting mirror, so that radiation can be radiated over a wide range or even when the human body moves, in order to realize comfortable radiant heating at all times. In this case, a plurality of lamps must be installed. As a result, the electric input becomes excessive and there is a problem in terms of energy saving.

  Halogen lamps as radiant heat sources are heat sources that are extremely compact, highly efficient, and have a radiation rise performance in a short time compared to other similar heat sources. The principle is the same, the filament life is several thousand hours, and it has the disadvantage of being relatively short.

  The present invention solves such conventional problems, and always realizes accurate radiant heating according to the movement of the human body, achieves energy saving and prolongs life by preventing forgetting to turn off.

Thus, the halogen lamp can be turned on only when there is a person, and energy saving can be realized.

  Further, human body position information is detected by a human body position recognizing unit that recognizes an approximate position of the human body, and infrared radiation and visible light emission from the light emitting unit are controlled in the human body position direction based on the human body position information. Thus, efficient radiant heating is realized with less electric input by controlling the heat beam following the movement of the human body. Furthermore, by making the position detection accuracy of the human body position recognition means equal to or higher than the direction control accuracy of the direction control means, the memory, arithmetic processing unit, etc. in the position detection processing can be realized in a compact manner.

  In addition, by detecting the temperature of the radiation surface with the human body detection means, the light emission output of the light emission means is controlled, so that it is possible to detect energy saving and abnormal temperature rise without emitting more radiation energy than necessary. It becomes possible.

  In addition, in the light emission output control means, by having a timed timer function that is driven from the time of lighting, the output of the light emitting means is cut off, the life of the halogen lamp is increased, and unnecessary lighting is prevented, Energy saving can be realized.

  1st invention provides the light emission means which discharge | releases infrared rays and visible light, and the human body detection means which detects a human body, and provides the control means which controls lighting and light extinction of the said light emission means by the output from the said human body detection means Thus, with this configuration, it is possible to turn on the light emitting means only when there is a person, thereby preventing unnecessary lighting and realizing energy saving.

By making the configuration, the degree of freedom of the irradiation angle is increased, and heating for a wide range is possible.

  The fourth invention comprises a light emission output control means for controlling the light emission output of the light emission means in accordance with the output from the human body detection means, and by applying this configuration, the radiation energy more than necessary is irradiated. And efficient heating can be performed.

  In the fifth aspect of the invention, the light emission output control means is provided with a time limit timer function and shuts off the output of the light emission means after a predetermined light emission time has elapsed. realizable.
