Description

Technical Field

[0001] The utility model relates to the field of reading lamp fixtures, and particularly to an intelligent eye-protecting reading lamp. Background Art

[0002] With the rapid development of LED technology, white light LEDs have become the focus of research in various countries due to their high luminous efficiency, environmental protection, long lifespan and many other advantages. In the existing technical field, the most common LED light source at present is to use the blue light emitted by a blue light chip to excite a phosphor to emit yellow-green light or yellow-green and red light, and then mix it with the remaining blue light of the chip to form white light. There will be a blue light peak below 500nm in its spectrum, and usually there is a relatively large power intensity at 445 - 455nm. Since the high-energy blue light spectrum range is 415 - 455nm, such a light-emitting mechanism hides the problem of harm to the eyes. The traditional approach is to lower the color temperature of the light source. Although the blue light radiation energy of the low-color-temperature white light LED light-emitting mechanism is very low and the blue light hazard is very small, too low a color temperature will cause inattention and fatigue.

[0003] In view of the above technical problems, the technology of converting purple light to white light LED has been emerging. The mechanism of obtaining white light by exciting a purple light LED is to excite a phosphor to emit light by the purple light emitted by the purple light LED, and the light emitted by the phosphor is mixed to obtain white light. In order to further improve the luminous efficiency, color rendering index, etc. of the purple light LED converted to white light and make it practical, the research on purple light LEDs has developed by leaps and bounds in recent years and has become one of the most active research fields at present.

[0004] The purpose of the present invention is to provide an LED reading lamp that converts purple light to white light to improve the disadvantages of the existing white light LED lamp with low color rendering and light biological hazards, and achieve the purposes of green lighting, protecting eyesight health, improving eye use comfort, and improving light biological safety.
