Problems solved by technology

After the above-mentioned blue light is irradiated on the human retina, it inhibits the secretion of melatonin through the human biological clock system, has a high physiological stimulation value, and helps to improve work performance. However, the blue light used in the general white light-emitting diode (White LED) light source module The main peak of light-emitting diodes is between 445nm and 460nm. According to the optical radiation biosafety standard IEC62471, the effective blue light hazard (Effective blue light hazard) caused by this band of blue light to the retina of the eye is the most serious.

Embodiment Construction

[0035] (first embodiment)

[0036] Figure 2A is a schematic diagram of the light source device in the embodiment of the present disclosure, Figure 2B according to Figure 2A A variation of the light source device in the embodiment, Figure 2C according to Figure 2B For the spectral schematic diagram of the relative light intensity and light wavelength of the light emitted by the light source device in the embodiment, please refer to 2A to 2C In this embodiment, the light source device 100 includes a light emitting module 110 and a control unit 120 . The light emitting module 110 provides light B. In this embodiment, the light B represents the light emitted by the light emitting module 110 , which may have a divergence angle, but is not limited to a specific transmission direction. The control unit 120 is used for switching the light B emitted by the light emitting module 110 to be the first light L1 or the second light L2. Wherein, the physiological stimulation valu...

Abstract

The present disclosure relates to a light source device and a lighting device, which can provide different physiological stimulation light. The light source device includes a light emitting module and a control unit. The light module provides light. The control unit switches the light emitted by the light-emitting module between the first light and the second light, wherein the physiological stimulation value of the second light is less than the physiological stimulation value of the first light, and the color temperature of the second light and the first light are substantially the same. .

Description

technical field [0001] The present disclosure relates to a light source device and an illuminating device, and more particularly, to a light source device and an illuminating device that can provide different physiological stimulation lights. Background technique [0002] With the invention of the light bulb by Thomas Alva Edison, the light source generated by electricity not only lights up the night, but also lights up human civilization. With this artificial light source, human beings can make use of the time at night, which further promotes technology and education development. In the research on the influence of light source on physiological stimulation, Yasukouchi found that the light source with high color temperature at night inhibits the secretion of melatonin more than the light source with low color temperature. Secondly, since 2001, Branard's research on the relationship between human eyes and physiological effects, further pointed out the relationship between li...
