EYE-PROTECTION DESK LAMP

WIPO Patent Application WO/2020/000516

A1

An eye-protection desk lamp comprises a light source assembly (1), a lamp pipe assembly (2), a control assembly (3) and a power supply assembly (4). The light source assembly (1) comprises a light source unit (11). The light source unit (11) comprises an LED light source (111) for producing near-natural light. The lamp pipe assembly (2) is connected to the light source assembly (1) to support the light source assembly (1). The control assembly (3) is connected to the LED light source (111) to control an operating state of the LED light source (111). The power supply assembly (4) is connected to the control assembly (3) to supply power to the control assembly (3) and the LED light source (111). Blue light in the near-natural light produced by the LED light source (111) has a color ratio less than 5.7%. The blue light in the near-natural light has a relative spectral power less than 0.75. Red light in the near-natural light has a relative spectral power greater than 0.60. Near-natural light emitted by the eye-protection desk lamp has reduced blue light and wavebands thereof fall within wavebands of natural light. Light components in the respective wavebands of the near-natural light have relative spectral powers similar to that of natural light.
