Problems solved by technology

Obviously, due to the large number of lamp beads, the overall failure rate of the corresponding multi-lamp bead desk lamp will greatly increase, so there is no such product on the market. This invention will use special measures to solve the reliability problem of the multi-lamp bead desk lamp

Embodiment 1

[0030] Embodiment 1: A kind of method that uses high-voltage specially designed incandescent lamp to form flicker-free low blue light full-spectrum desk lamp, see figure 1 , which corresponds to N=Nc=Nb=1 at this time; the design requirement of the high-voltage special design incandescent lamp 4 is that its rated operating voltage is greater than or equal to the voltage of the DC power supply, the greater the difference between the two voltages, the lower the color temperature of the lamp (that is, the closer the spectrum is to Candlelight); the less blue light content; the longer the life of the bulb; the lower the temperature of the glass bulb; 2 is filtered. In order to reduce stroboscopic flicker, the higher the power of the desk lamp, the larger the required capacitance; for a 25W desk lamp, 80-150 microfarads is preferred; at this time, the detection with the ocean spectrometer (sampling time is set to 1mS) can no longer detect the spectrum jumping ( The overall beating...

Embodiment 2

[0031] Embodiment 2: A kind of method that uses two commercially available incandescent lamps to form no flicker low blue light full-spectrum desk lamp, see figure 2 . At this time Nc=2, Nb=1. The selection method of the incandescent lamp 6 is as follows: the rated voltage of a single incandescent lamp 6 is V, the rated working voltage of two incandescent lamps 6 connected in series is 2V, and the voltage of the DC power supply is Vd (such as figure 2 310V), then this embodiment requires 2V≧Vd, ​​and the greater the difference (2V-Vd), the lower the color temperature of the desk lamp (that is, the closer the spectrum is to candlelight); the less blue light content, the longer the life of the incandescent lamp 6, The lower the temperature of the glass bulb, the less glare; the difference between this step and the incandescent lamps powered by low-voltage DC on the market is that a lower color temperature can be further selected. The so-called low-voltage DC power supply ref...

Embodiment 3

[0032] Embodiment 3: A configuration method of a desk lamp powered by 24V DC power supply, equipped with 24 6V small incandescent lamp beads and equipped with fault detection and automatic switching of LED lamps. See image 3 , this is a successfully debugged circuit, and the parameters of each component have been marked in the figure. At this time, Nc=4, Nb=6, and the power of each lamp bead is 2W under the rated voltage of 6.7V, that is image 3 The middle C1 low-voltage incandescent lamp 7 is the first incandescent lamp bead in series in this row, the meaning of C2 low-voltage incandescent lamp 8 and C3 low-voltage incandescent lamp 9 is similar, and the Ce low-voltage incandescent lamp 10 is the last incandescent lamp in this row Beads; the total rated voltage of the 4 incandescent lamp beads in this row is 6.7×4=26.8V, which is greater than the voltage of the 24V low-voltage DC power supply, so the actual color temperature of the lamp beads will be lower than the rated v...

Abstract

The invention discloses a method for forming an incandescent-lamp-composed flicker-free low-blue-light full spectrum special light. The special light adopts a high voltage direct current power supply (310V) for power, making the special light flicker-free and solving the fundamental problems of an incandescent lamp. According to the method, two ordinary light bulbs are used and connected in series to equally spread the 310V direct current voltage, which further reduces the color temperature of the incandescent lamp, further reduces the blue-ray hazards, promotes the visual and non-visual health, and extends the service lifetime of incandescent lamp as well as reduces the dazzling light and the surface temperature of the incandescent lamp, therefore, making the use of the incandescent lamp more secure. The method promotes the multiple new illumination ideas for low illuminations and holds that under special illumination, the deeply red part and the infrared waveband of the incandescent lamp have health significance, and are not all entirely a waste of energy. The invention also discloses a method for forming a light powered by low voltage and consisting of a plurality of incandescent lamp beads. The disclosed method is assessed by experiments, and the light quality is ensured to be perfect, making the special light of profound significance to the health and reproducing of the Chinese nation.

Description

technical field [0001] The invention relates to the field of lighting, in particular to a method for forming a flicker-free low blue light full-spectrum special lamp with an incandescent lamp. Background technique [0002] In recent years, research on the "non-visual function" of the human eye has become increasingly in-depth, and the hazards of blue light have gone far beyond the scope of "visual function". The current situation is: in terms of "visual function", my country's "myopia prevention and treatment" in the past ten years can be said to be a complete failure, which may mean that the direction is wrong; The phenomenon of "precocious puberty", "breast cancer", "diabetes" and "obesity" caused by the secretion of the most basic human hormones such as "cortisol" and "cortisol" is attracting widespread attention. In 2016, CIE, ISO, AMA (American Medical Association) Both warnings may be recommended. The inventor of the present invention also took the lead in asking: chic...
