Description

Method for filtering harmful wavelengths in a beam emitted by an irradiation light

The present invention relates to a method for filtering harmful wavelengths in a beam of irradiation light, and in particular to a method for directly contact cooling a halogen lamp with a flowing circulating cooling liquid, and for filtering harmful wavelengths of ultraviolet light and blue light in the irradiation light beam emitted by the halogen lamp.

According to the information provided by the sun, in addition to visible light, there is also light that cannot be seen by the eyes, such as ultraviolet light and infrared light. Figure 1 shows the spectrum of common sunlight. Ultraviolet light is the general term for radiation with a wavelength from 10nm to 400nm in the electromagnetic spectrum. Blue light is the blue part of the solar spectrum in the figure, with a wavelength from about 400nm to 480nm, as shown in the circled range of A in the figure. Ultraviolet light can harm the skin and eyes, and blue light in the visible light range can also harm the eyes.

Press once, and infrared rays will penetrate 40 mm deep into the human skin, promoting self-heating, increasing the temperature deep inside the body, enhancing metabolism, activating cell tissues, promoting the excretion of toxins and waste in the body and relieving fatigue.

FIG2A shows a schematic diagram of a hand infrared irradiation lamp 50, FIG2B shows a schematic diagram of a foot infrared irradiation lamp 60, and FIG2C shows a schematic diagram of a body infrared irradiation lamp 70. However, generally speaking, infrared lamps are not suitable for thermal therapy because the infrared wavelength is relatively long, so the heat generated by the high temperature will be directly transferred to the human skin, which may cause skin burns or blackening.

Therefore, most infrared irradiation at present is mainly based on halogen lamps, which have an irradiation effect; because the spectrum of halogen lamps is actually the closest to the spectrum of sunlight, and it is a full-wave spectrum, so the spectrum it emits follows blackbody radiation, the spectrum continuity is very good, and it basically has the same color rendering as sunlight. And its color temperature is generally 3000K+, which belongs to warm tones. When viewed with the naked eye, it will give people a warm and comfortable feeling. However, it is found that the irradiation beam of halogen lamps still contains ultraviolet light and blue light. In addition, the working temperature of halogen lamps is as high as 324.4 degrees Celsius, so the heat dissipation of infrared tubes composed of halogen lamps is one of the main problems.

Next, as shown in FIG. 3A and FIG. 3B, the inventor's previous invention, Taiwan Publication No. I759217 "Safety Monitoring Management System for Phototherapy Machine", includes a cabin 80, the internal space of which can accommodate a user's human body, and a plurality of infrared light sources 81 composed of halogen lamps installed in the cabin 80. The infrared light source 81 uses the thermal radiation energy generated by the infrared light source to irradiate the human body inside the cabin 80, thereby achieving the purpose of improving local blood circulation and relieving muscle fatigue and soreness. However, it is found that this method of using infrared thermal radiation energy to Phototherapy machines that irradiate the human body place the entire body in a cabin and irradiate the body with thermal radiation energy at a temperature of 40℃~45℃ to achieve the best effect. However, it is found that halogen lamps are high-temperature heat sources. If liquid is used to dissipate the heat of the halogen lamp, but the heat dissipation liquid cannot maintain a certain cooling temperature, the heat dissipation effect of the halogen lamp will be poor, which will easily reduce its service life, and change the lumen and color temperature of the halogen lamp, so that the beam of irradiation light still contains harmful wavelengths of ultraviolet light and blue light, which will damage the human skin and eyes.

In view of the above problems, the inventor has been adhering to the spirit of continuous improvement and actively researching and improving, in order to effectively solve the problems of high temperature heat dissipation of halogen lamps and filtering harmful wavelengths in the light beam.
