Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with the accompanying drawings and specifically
This utility model is described in further detail by embodiment.
In this embodiment, in order to be best understood from eye protection illuminator in this enforcement, background context knowledge, Fig. 1 are first introduced
For this utility model one embodiment provide rgb light be mixed into white light time colour temperature numerical value schematic diagram.Colour temperature is that ideal black-body is heated
Rear luminescence, represents its glow color by the temperature (absolute temperature K) being heated.Colour temperature is the lowest, and color is the reddest, claims warm tones；Color
Wen Yuegao, partially blue in white color, claim cool tone.Such as white balance in camera is arranged, and is the colour temperature setting " standard white ", it is simply that
Determine that white is mixed into by the most blue, green, red.Colour temperature refers to weigh the definite value of light color, and unit is K, represents light source
The index that spectral quality is the most general；Wherein, changes in temperature light also makes a distinction according to colour temperature, when: K < 3300 is warm colour light；K>
3300 is cool colour light；K > 6000 white light；Cool colour light is higher than the blue ray radiation of warm colour light, and white light blue ray radiation is the highest；It addition, court
Sun setting sun average color temperature is close to 2000K, and 10:00 to 15:00 puts sunlight average direct projection colour temperature close to 6000K.
Wherein, LED is the principle formation illumination being mixed to form white light by rgb light.As it is shown in figure 1, white point is required three
Primitive color light (rgb light) proportioning, and colour temperature is to be determined color temperature value by RGB three primary colors light source coordinates line delta-shaped region.In conjunction with table
1, table 1 is white light and rgb light proportioning and related color coordinate figure information.
Table 1 is white light and rgb light proportioning table；
In conjunction with table 1 it can be seen that white point is closer to redness, color temperature value is the least and red luma is the brightest and blue luminences more
Secretly；Therefore, in actual applications, the change of colour temperature can be realized by the proportioning changing rgb light；And the proportioning of rgb light can
Realize with the driving electric current by change R.G.B light source.
