TWI244105B - Full spectrum fluorescent tube - Google Patents

Abstract

The present invention provides a full spectrum fluorescent tube whose main structure comprises a glass light tube and argon filled in the glass light tube. The internal of the glass light tube is coated with fluorescent powder and an electrode is applied to seal the two ends of the glass light tube. When the light tube is provided with a current and tested by a spectrum analyzer, the spectrum curve (energy) is continuous and can form at least seven peaks in the wavelength range of 380 to 780 nm. Since the seven peaks are closed to the wavelength positions of visible lights, including red, orange, yellow, green, blue, indigo, and violet, a full spectrum light source is formed. Thus, it is able to obtain a high quality light tube, whose color rendering index (Ra) is greater than or equal to 90 and color temperature (Tc) is between 2800K and 6500K.

It is mainly simply adding and mixing the spectrums of the three wavelengths of orange, green, and indigo to produce white light that is close to sunlight. Three-color light fluorescent powder, while the orange is composed of Y202: Eu, the green is composed of (CeTb) MgA2Alu019, and the astigmatism is composed of BaMgAl 1 6 0 27: Eu; according to the artificial light source generated when the current passes The analysis chart measured under the spectrometer (as shown in the first figure), in the visible light range of 380 ~ 780 nm, its spectral curve (energy) will be corresponding to the lamp (615nm), green (545nm) ), 彀 (435nm) light waves form three peaks with higher luminous energy, the energy of the remaining visible light is relatively weak, and even a discontinuous situation will appear on the spectrum (energy) curve (1 0) (such as respectively The energy ratio is 0% at the positions of 570 nm, 650 nm and 705 nm, so it is a three-wavelength light source with a color temperature of 6500 K and color rendering (R a) S 8 0 , And do not work or read in this state for a long time, and the items you see will produce Lack of chromatic aberration. Even a five-wavelength or seven-wavelength fluorescent tube, if the wavelength curve measured by the spectrometer is discontinuous, is not a complete natural light source of the full-spectrum seven-wavelength, which cannot achieve the best lighting effect.

The simulated full-spectrum fluorescent tube of the present invention mainly includes at least one glass lamp tube coated with fluorescent powder inside and sealed at both ends with electrodes, and argon gas filled therein; its characteristics are as follows: When the tube current is detected by the spectrometer (as shown in the second figure), its spectral (energy) curve (1 0) in the wavelength range of 3800 to 780 nm is uninterrupted; and red The light wavelength range is between 780 ~ 630nm, orange light is 630 ~ 590nm, yellow light is 590 ~ 560nm, green light is 560 ~ 490nm, blue light is 490 ~ 470nm, Yi 1244105 Case No. 92113769 Amendment V. Description of the invention (4) Color light 470 ~ 420nm, purple light 420 ~ 380nm, and at least seven peaks can be formed in the spectrum (energy) curve (1 0), these peaks are close to red (7 1 0 nm), orange (6 1 5 nm) , Yellow (5 8 5 nm), green (5 4 5 nm), blue (490nm), indigo (435nm), violet (405nm) and other visible light wavelength positions to form an artificial light source that simulates full light. In addition, the light wave energy ratios of the above red, orange, yellow, green, blue, indigo, and purple are approaching red (8%), orange (67%), yellow (25%), and green (1 0 0). %), Blue (33%), indigo (62.5%), purple (24%), it can obtain color rendering (R a)-9 0 and color temperature (T c) at 5 5 0 0 K of the best

Effect; and the proportion of these light wave energy can also be adjusted to change its color temperature according to actual needs, but the wave width still needs to be maintained in the state of uninterrupted light waves and seven colors of light. Reached. As described above, the components of each color of fluorescent and light powder can be modulated with five colors of fluorescent powder. For example, the conventional orange is composed of Y2 02: EU, the green is composed of (ce T b) MgAJlnOB, and indigo. In addition to the composition of BaMg2Al16〇27 :, red can also produce a small amount of peak at 710nm from Y2O2: Eu, and yellow light from orange and green, blue from Sr4Ali4〇: Eu, and purple It is composed of Hg and generates a peak at 405 nm. As mentioned above, the same technique must be used to directly synthesize a single phosphor material covered with seven color light wavelengths. /

According to the above, according to the color mixing principle of color physics theory, it can be known that the essence of the three primary colors is that the three primary colors are independent. Any of the three primary colors cannot be synthesized with the remaining two colors, and the two primary colors have the largest mixed color gamut. Can be mixed from three primary colors in a certain proportion, 1 and mixed

1244105 Case No. 92113769 means that the number of colors obtained after the amendment of the fifth and the invention description (5) is the most; In addition, in the white light dispersion test, we can also observe that the three colors of red, green and blue are more evenly distributed throughout the visible spectrum. In addition, it occupies a wide area. Generally, at least the three primary colors of red, green, and blue can be added to synthesize white light. However, this white light still has color difference with sunlight. It can be seen that the iridescence of the seven-color light can be obtained that the sunlight is not available in the ordinary three primary colors. Therefore, the light source produced by the present invention can include red, orange, yellow,

White light, which is a mixture of seven colors of green, blue, scattered, and purple, is a full-spectrum light source that is closest to natural sunlight, and its color rendering (Ra) -90 and color temperature can reach 2800K to 6500K. Therefore, it is a high-quality lamp with soft light and clear color without distortion. In summary, the "full-spectrum fluorescent tube" of the present invention can indeed provide a comfortable and natural light source lighting appliance, so that users can easily read or work, reduce eye fatigue and burden, and achieve eye protection effects. The use value of this case can meet the requirements of the invention patent of the Patent Law; the applicant has applied for an invention patent application to the Bureau in accordance with the provisions of Articles 19 and 20 of the Patent Law, and urges early approval. The patent in this case is really good.
