Description

Technical Field

[0001] The utility model relates to the technical field of table lamps, in particular to an eye-protection table lamp. Background Art

[0002] The human eye was formed and evolved under natural light, and the adaptability of vision to natural light is irreplaceable. When the eyes look at pure blue light, the eyes will open wider unnaturally, so that the image of the blue light falls on the retina; when the eyes look at pure red light, the eyes will squint unnaturally, so that the image of the red light falls on the retina.

[0003] Ordinary light strips or light panels, if there is no blue LED and white LED, there is no blue light. If there is a red LED, there is red light. The red light that is beneficial to the human body is the red light in the 640-700nM band. White light LEDs are usually formed by two methods. The first is to use "blue light technology" with phosphors to form white light, such as covering the blue LED chip with phosphors to obtain white light; the second is a method of mixing multiple monochromatic lights, such as mixing red light, green light, and blue light to form white light. Red LEDs do not have blue light components.

[0004] Desk lamps are household appliances used for lighting in people's lives. LED lighting is energy-saving, environmentally friendly, safe and reliable. Among them, LED desk lamps are desk lamps that use light-emitting diodes as light sources. For example, the Chinese utility model patent with authorization announcement number CN203190181U discloses a brightness-controllable LED white light desk lamp, which designs the traditional LED white light panel into three controllable panels. This design can effectively control the three LED white light panels independently, but the LED white light panel lacks red light spectrum and has too high blue light spectrum. After long-term use of the eyes, it can not only damage the retinal macular area, but also easily cause "eye fatigue" and form myopia. Therefore, it is necessary to design an eye-protection desk lamp that strengthens the red light spectrum in the lighting spectrum. Utility Model Content
