Description
Technical field
The present invention relates to a kind of healthy LED illuminating lamp, relate in particular to a kind of children ' s vision and healthy LED illuminating lamp protected.
Background technology
LED is the core devices of semiconductor lighting, because it is that PN junction is luminous, has 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 the basic blue-ray LED luminescent device of gallium nitride (GaN) successful development, obtain fast development based on the white light LEDs technology and the industry of blue chip.
The basic blue-ray LED lighting of gallium nitride (GaN) has progressed into the room lighting field, but because of LED contains stronger blue spectrum, strong excessively blue light also is the No.1 killer of human eyesight." blue light " also is the important adjuster that human body keeps normal 24 hours life rhythms simultaneously, and blue light had obtained confirming on science to inhibition and other Immune Effects of human body epiphysin 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 (it transmits consider oneself as nervi vertebralis and the neural signal of retinal rod) of previous discovery.This and the second neural channel of article one neurotransmission channel parallel; The induced signal part of department's occasion cell is reached pineal body through part after the chiasma opticum system; Regulate the secretion of epiphysin, coordinate the activity rhythm in the different periods with the control people.
By day, human body needs a certain amount of blue light to stimulate, and peak wavelength is the blue light illumination about 464nm, and the secretion of human body epiphysin is had inhibitory action, makes the people in high spirits, helps increasing 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 important macular region of retina.Blue light has increased it thereby the damage effect of retinal pigment epithelium has been caused the atrophy of retinal pigment epithelium, causes the apoptosis of photaesthesia cell.The death of photaesthesia cell will cause eyesight to descend gradually even completely lose.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 the infant uses especially notes 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, through the control to lamplight brightness and colour temperature, improves people's comfort.The illuminator of the imitative sunlight of similar employing LED is also arranged, be used for simulating the colour temperature of different time sunlight.But, and do not have direct correspondence with department occasion effect curve because same colour temperature can be by multiple spectral composition.And a kind of healthy LED illuminating lamp of inventor invention is the basis with mediator's physiological parameter department occasion effect ratio (C/P value), and the adjusting of combination light intensity and the above two are different, more meets the demand of health.
Summary of the invention
The object of the present invention is to provide a kind of healthy LED illuminating lamp,,, reach needed optical radiation requirement through controlling the led light source of different C/P values and light intensity according to the human body photobiology health requirements of one day different time; For obtaining to cut the led light source of blue light, set up the optical lightscreening layer simultaneously, stop a large amount of outgoing of shortwave blue light, help health, solve the problem of shortwave blue light person deleterious impact; Simultaneously, also also excitated fluorescent powder is luminous once more with the shortwave blu-ray reflection in the present invention, has both reduced blue ray radiation, improves the luminous efficiency of fluorescent material again.
And the healthy LED illuminating lamp that patent application of the present invention relates to; Be on the basis of sensitization spectral position of human eye retina's photochemical damage a kind of health type LED illuminating lamp that is specially adapted to infant of design just at emission spectrum to the basic blue-ray LED of gallium nitride (GaN).The illuminating source of this lamp is made up of two kinds of branch light sources at least; And spectrum is variable; Be a kind of can be in time variation department occasion effect ratio (C/P value) or change the lighting of C/P value automatically according to control model, especially ended the radiation of shorter wavelength blue light, effectively prevented the harm of blue light to human eye.The illuminating lamp that can be used as the infant of family uses.Wherein, department's occasion effects ratio C/P value is meant the ratio of taking charge of occasion effect Circadian rhythm and photopic vision effect Photopic vision, is used for estimating the power of the non-visual biological effect of light source.Computing formula is following:
Wherein, P (λ) is the spectral power distribution of illuminating lamp, and C (λ) is the spectral luminous efficiency curve of department's occasion effect, and V (λ) is a photopic vision spectrum light efficiency function.
There is certain incidence relation between C/P value and the light intensity.Wherein, light intensity described in the present invention and luminous intensity are not notions, and luminous intensity is the base quantity of luminosity, and light intensity only is a kind of parameter of the size of light, and light intensity can be luminous flux, luminous intensity, illuminance or brightness etc. among the present invention.
The present invention solves the technical scheme that the prior art problem adopted: a kind of healthy LED illuminating lamp, comprise the driving power of illuminating source, driven for emitting lights light source and the control device that is connected with the driving power signal, and it is characterized in that:
