Description

A kind of illuminating lamp of simulating nature photo bio effect

Technical field

The utility model relates to a kind of illuminating lamp that is of value to health, particularly is applicable to the illuminating lamp of a kind of simulating nature photo bio effect of enclosed environments such as human settlements such as indoor office, family and aircraft, submarine illumination.

Background technology

In the life, being regardless of or the like round the clock in incompatibility in changing shifts of the time difference problem of passenger in circumnavigation, night shift workman, the astronaut's space, it is incompatible to have proved that all human body lacks the caused physiology of normal natural light irradiation.

Adopting led light source to be used for illumination exists plurality of advantages and enjoys favor; Have that energy-saving and environmental protection, life-span are long, fast, the anti-switching surge of response, be prone to advantages such as luminous intensity distribution such as it, quicken to be penetrated into the room lighting field owing to the lifting of led light source light efficiency and the rapid decline of price recently.Yet led light source is little and bright, and contains stronger blue light wave spectrum, can cause certain light to pollute.Therefore, led light source also more and more is much accounted of the pros and cons of health of human body.

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 the illuminating lamp of a kind of simulating nature photo bio effect of inventor invention, department occasion effect ratio (C/P value) relevant with mediator's physiological parameter be the basis, and combination light intensity adjusting and aforementioned both are different, more meets the demand of health.

Summary of the invention

The purpose of the utility model is to address the above problem and a kind of illuminating lamp of simulating nature photo bio effect is provided, through the control combination light source each minute light source luminous intensity, come final C/P value of control combination light source and light intensity to change with the variation of control signal; Reach the effect of simulating nature light; And the advantageous effect of lifting lighting source, reduce drawback, reduce light pollution; The health that helps health improves the light comfort level.

The technical scheme that the prior art problem that solves the utility model is adopted is: a kind of illuminating lamp of simulating nature photo bio effect, comprise illuminating source, the driving power that is electrically connected with illuminating source, and the control device of controlling and driving power supply, it is characterized in that:

Also comprise the control-signals generator that is connected with the control device signal;

Described illuminating source comprises first fen light source and second fen light source at least, described first minute radiative C/P value of light source greater than 3.0, the second fens radiative C/P values of light source less than 2.5;

One group of C/P value of described control device stored and light intensity information data, i.e. simulating nature optical information; The described control-signals generator control device that sends control information; Described control device divides control signal of light source light intensity size to arrive driving power according to the control information output of input corresponding to each; Described driving power is controlled the luminous intensity of each minute light source respectively, makes illuminating source form the light source with corresponding C/P value and light intensity.

The discovery of the third photosensory cell that exists in the human body (department's occasion sensitization nerve cell) just in time can help the human problem of understanding and solving the prior art existence.Department's occasion sensitization nerve cell 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.Second neural channel with article one neurotransmission channel parallel; The part of the induced signal of taking charge of the occasion cell is reached pineal body afterwards through the chiasma opticum system; Regulate the secretion of epiphysin, play the effect of administrative time, coordinate and control the activity rhythm of people at different time.

According to the report of Commission Internationale De L'Eclairage's issue, the peak value of the spectral luminous efficiency curve of department's occasion cell is about 464nm.By day the operating time, peak wavelength is that the blue light about 464nm passes through eye irritation, can suppress the secretion of human body epiphysin, makes the people in high spirits, helps increasing work efficiency; And time of having a rest, particularly evening, human body need loosen, and should reduce the stimulation of blue light.And the variation of lamps such as the sun, flame is exactly consistent with people's photobiology characteristic, and the operating time can be in high spirits by day to make people, and the time of having a rest can well be loosened rest again.

The inventor invents a kind of light source in view of the above, an illuminating source that spectrum is variable of being made up of at least two kinds of branch light sources.And be designed to illuminating lamp a kind of simulating nature light, that can need to change automatically C/P value and light intensity with use based on this, make people's physical efficiency reach best work or resting state.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:
