Description
Technical field
The present invention relates to a kind of healthy LED illuminating lamp, relate in particular to a kind of child protection eyesight and healthy LED illuminating lamp.
Background technology
LED is the core devices of semiconductor lighting, because it is that PN junction is luminous, has the plurality of advantages such as high brightness, high light efficiency, long-life, environmental protection, and being applied in recent years of it developed fast.Especially after gallium nitride (GaN) base blue-ray LED luminescent device is researched and developed successfully, white light LEDs technology and industry based on blue chip are rapidly developed.
Gallium nitride (GaN) base blue-ray LED lighting has progressed into room lighting field, but because LED contains stronger blue spectrum, excessively strong blue light is also the No.1 killer of human eyesight." blue light " is also the important adjuster that human body keeps normal 24 hours life rhythms simultaneously, and blue light was confirmed on the impact of the inhibition of human body epiphysin and other immunologic function in science in recent years.
The David Berson of Brown Univ USA professor's in 2002 team has found the third photosensory cell (also title department occasion sensitization nerve cell) of human eye.It is a kind of non-vision sensitization nerve cell, and the transmission channel of its photoreceptor signal is different from article one neural pathways for vision signal of nervi vertebralis and retinal rod nerve (it transmit to consider oneself as) of previous discovery.This and the second neural channel of article one neurotransmission channel parallel, an induced signal part for department's occasion cell is reached to pineal body through part after chiasma opticum system, regulate the secretion of epiphysin, coordinate and control the activity rhythm of people in the different periods.
By day, human body needs a certain amount of blue light to stimulate, and peak wavelength is the blue light illumination of 464nm left and right, and the secretion of human body epiphysin is had to inhibitory action, makes people in high spirits, is conducive to increase work efficiency; And time of having a rest, particularly evening should reduce the stimulation of blue light, make human body fully secrete epiphysin, obtain loosening rest.In addition,, between the 380-500nm of spectrum, a large amount of high energy shortwave blue lights can penetrate our crystalline lens and vitreum, directes reach the most most important macular region of retina.Thereby blue light has increased it and the damage effect of retinal pigment epithelium caused to the atrophy of retinal pigment epithelium, cause the apoptosis of photaesthesia cell.The death of photaesthesia cell will cause eyesight to decline and even completely lose gradually.And the spectral energy of ultraviolet band is mainly sponged by crystalline lens, but the spectral-transmission characteristics of the human lens of all ages and classes section is different.The shortwave of children's eyes (near ultraviolet and blue light) transmittance is high, so the LED illuminating lamp that infant uses especially should be noted black light and blue light harm.
PHILIPS Co. has released a dynamic context illuminator at present, can regulate the white light of multiple different-colour according to the variation naturally of indoor light, by the control to lamplight brightness and colour temperature, improves people's comfort.Also the illuminator that has the imitative sunshine of similar employing LED, is used for simulating the colour temperature of different time sunshine.But because same colour temperature can be comprised of multiple spectrum, and do not there is direct correspondence with department occasion effect curve.And a kind of healthy LED illuminating lamp of inventor invention, mediator's the physiological parameter department occasion effect ratio (C/P value) of take is basic, and in conjunction with light intensity adjusting, and the above two are different, more meet the demand of health.
