The most appropriate LED illumination luminaries is colour temperature limits, should be those who approach sun nature white light is colour temperature limits just is the most scientific choice; The natural Bai Guang of inferior illuminate intensity, can achieve the illuminate result that other blame cannot compare naturally solely in vain; Most limits of road surface brightness should be in 2cd/m2 less than; Raise illume total uniformity and eliminating dazzle is energy-saving fall the most efficient way of bad news.

Foreword
In the time of lamp of natrium of incandescent lamp, high pressure, people compares what bright lamp provides is colour temperature the leeway that did not choose, be forced to be accepted silently with suit. But, it is OK to was entered the times of LED illumination luminaries with colour temperature choice, the LED illumination luminaries with what kind of choice is colour temperature, became a problem that has clear sober view to it urgently. This is thing joint can the important matter with lighting quality, the look does not get us to be answered cursorily.
Have a kind of view, apt moves the hobby that uses Europe, those who choose 2700-3200K is colour temperature limits. Allegedly this is European preference is colour temperature limits. To this, oneself have different view, put forward to discuss with everybody sincerely:
1, the person head identifying to the thing and respondent mechanism
Person head gets the first response of outside thing image through the eye, the image that gets place namely and store in cerebrum information photograph compares the image in recalling form to be opposite and identify originally, make corresponding respondent motion immediately then. If what get image information and former memory information are more adjacent, identified rate is rapidder, respondent nimbler also. Driver if be in,differ with natural by day light in the evening further low colour temperature below lamplight, the identifying of the image that gets to place is more arduous, identify rate slower, respondent speed also is jumped over accordingly slow. The result that respondent speed decelerates 0.1 seconds yields accident occurence rate with respect to enough abruptly dash forward add. The blemish that to amend scene of this kind of day and night place of lukewarm difference illume brings, only way increases illume strength namely, be in in order to rise low colour temperature the identifying below speed, this is meant increase specific power consumption.
Driven content evolution arrives tens of ten thousand years of the mankind are long among the process, the mankind is the natural light that lives in the sun all the time next, having all production and social activity. Endless nature chooses the result with evolution, make human eye most those who suit is colour temperature limits is sun nature Bai Guang is colour temperature limits (5500-7500K) . Human eye is in this colour temperature inside limits, to moving, of still life body differentiate capability is the strongest; In this colour temperature inside limits, the mankind is the nimblest also to the respondent ability of outside thing. Because, people cerebra remembers the object image news that stores inside information library, form below the illuminate of natural Bai Guang mostly. So, of the most appropriate LED illumination luminaries colour temperature limits, should be those who approach sun nature white light is colour temperature limits, just be the most scientific choice.
