Description
Technical field
The present invention relates to digital home technical field, be specifically related to the System and method for of a kind of the elderly of adjusting lamplight brightness and colour temperature while reading.
Background technology
Intensity of illumination refers to the energy of the visible ray of accepting in unit are, is called for short illumination, unit lux (Lux or Lx).Theoretically, people, when reading, in the higher environment of illumination, can obtain better euphorosia degree.But illumination is not more high better, and forceful rays can cause that people's vision discomfort even produces dazzle.Research discovery, when illumination is not too large, euphorosia degree increases with illumination, and when illumination is increased to a certain value, euphorosia degree reaches maximum 1, and when illumination continues to increase, euphorosia degree reduces gradually afterwards.If the overlong time of reading continuously under the bad environment of illumination condition, is easy to asthenopia.Improve lighting quality, improve reading condition, comfortable, a healthy lighting environment is provided, become a kind of demand that many elderlys generally pay attention to.
In general the elderly's eyesight has degeneration in various degree, and most the elderlys' eyes have astigmatic symptom.And the elderly of different astigmatic degree has different demands to the illumination of light source when reading.So, light illumination is combined and seems particularly necessary with reading comfort level.
Conventional this concept of colour temperature of color of light source represents.The radiation of light source is when the radiation of visual field and absolute black body is identical, and now the temperature of black matrix just claims the colour temperature of this light source.The feature of low color temperature light sources is in Energy distribution, and the relative theory of red radiation is some more, is commonly referred to " warm light "; After colour temperature improves, in Energy distribution, the ratio of blue radiation increases, and is commonly referred to " cold light ".People is relevant with illumination level to the hobby of colour temperature.Nineteen forty-one Germany gram Lv doffer, according to experiment, proposes the scope of photochromic comfort zone first quantitatively.In Germany gram Lv doffer's experiment, draw the conformity relation of illumination, colour temperature and sensation.Experiment shows, the elderly of different astigmatic degree also has different demands to the colour temperature of light source when reading.
Therefore,, according to the rule of reading comfort level variation under Different Light illumination and colour temperature, can, according to the difference of the elderly's astigmatism degree, select the light source of different illumination and colour temperature, for the elderly provides a comfortable reading luminous environment.
Under normal circumstances, the thermostasis of human body and higher than ambient temperature, towards periphery infrared radiation.Passive type infrared inductor itself is not launched any energy and only passive reception, is surveyed the infrared radiation from environment.Once have human body infrared beta radiation to come in, focus on and just make pyroelectric electric device produce the sudden change signal of telecommunication through optical system, and enable load.
