If*f(x,sE)＝k*Iw*f(dD,sE)*f(dE,sE),k<<1 (4)
Wherein, in an embodiment of the present invention, according to certainty of measurement requirement, desirable k is 0.1 or 0.01.Afterwards, can derive according to above-mentioned formula (4), obtain x value, be appreciated that distance between photometric measurer 30 and illuminating part 20 minimum for this x value time, the light that illuminating part 20 is launched can not have influence on the measurement of photometric measurer 30, therefore, and can using this x value as the first spacing X1.
Optionally, in one embodiment of the invention, other parts of above-mentioned light penetrating panel 10 can be formed with predetermined pattern.Wherein, in an embodiment of the present invention, predetermined pattern can be the coloured pattern of tool, also can be do not have coloured transparent pattern, the coloured peony of such as tool, Little Bear, rabbit etc.Thus, improve the attractive in appearance of panel.
Preferably, clear for making the display luminous component in air-conditioner (illuminating part 20 namely in the embodiment of the present invention) show through light penetrating panel 10, improve user satisfaction, in one embodiment of the invention, double face slab structure can be adopted, internal layer adopts the material of low astigmatism rate, and the outer material adopting high astigmatism rate, concentrates on the display part in air-conditioner with the position allowing to luminescence.Particularly, according to one embodiment of present invention, as shown in Figure 3, light penetrating panel 10 can comprise the first photic zone 13 and the second photic zone 14.Wherein, in an embodiment of the present invention, as shown in Figure 3, illuminating part 20 and photometric measurer 30 can be arranged on the side of the first photic zone 13, second photic zone 14 can be arranged on the opposite side of the first photic zone 13, and wherein, the astigmatism rate of the second photic zone 14 is greater than the astigmatism rate of the first photic zone 13.That is, it is the internal layer of light penetrating panel 10 that the first photic zone 13 can be understood, and it is the skin of light penetrating panel 10 that the second photic zone 14 can be understood.
Be to be understood that, owing to adopting the inner layer material of low astigmatism rate, propagate causing the light of illuminating part 20 from internal layer panel (i.e. the first photic zone 13) and could decay comparatively at a distance, if photometric measurer 30 close together, this light source can be received, thus affect the degree of accuracy of the measurement of external environment condition light intensity, therefore the distance L2 between illuminating part 20 and photometric measurer 30 will be increased, make If*f (x, sC) <<Iw*f (dB, sB) * f (dC, sC), that is:
If*f(x,sC)＝k*Iw*f(dB,sB)*f(dC,sC),k<<1 (5)
Wherein, k in above-mentioned formula (5) is coefficient and 0<k<1, Iw is external environment condition light intensity, dB is the thickness of the second photic zone 14, sB is the astigmatism rate of the second photic zone 14, dC is the thickness of the first photic zone 13, and sC is the astigmatism rate of the first photic zone 13.
In addition, in an embodiment of the present invention, according to certainty of measurement requirement, desirable k is 0.1 or 0.01.According to above-mentioned formula (5), the second default spacing X2 can be drawn:
X2＝-ln(k*(Iw*(e^(-dB*sB))*(e^(-dC*sC)))/If)/sC (6)
Wherein k is coefficient and 0<k<1, Iw are outside light intensity, and dB is the thickness of the second photic zone 14, sB is the astigmatism rate of the second photic zone 14, dC is the thickness of the first photic zone 13, and sC is the astigmatism rate of the first photic zone 13, and If is the transmitting light intensity of illuminating part 20.
Like this according to this second spacing X2, as long as the actual range L2 between photometric measurer 30 and illuminating part 20 is greater than this second spacing X2, then can ensure the impact of the light that photometric measurer 30 light-metering precision is not sent by illuminating part 20.
Thus, by adopting double face slab structure, internal layer adopts the material of low astigmatism rate, the outer material adopting high astigmatism rate, the display part in air-conditioner is concentrated on the position allowing to luminescence, display luminous component light-transmitting panel in air-conditioner is shown clear, thus improve user satisfaction.
Wherein, according to one embodiment of present invention, the arrival light intensity that illuminating part 20 scatters to the relative Part I of photometric measurer 30 by light penetrating panel 10 obtains by following formulae discovery:
In＝If*f(x,sA) (7)
Wherein In is above-mentioned arrival light intensity, and If is the transmitting light intensity of illuminating part 20, and f (x, sA) is that x is the distance between photometric measurer 30 and illuminating part 20, and sA is the astigmatism rate of light penetrating panel along with the scattering function apart from exponentially type decay; Wherein, total light intensity that photometric measurer 30 detects is less than light intensity activation threshold value with the difference arriving light intensity.
Particularly, external environment condition light intensity Iw can be obtained more accurately to make photometric measurer 30, in an embodiment of the present invention, the arrival light intensity that total light intensity that can record according to photometric measurer 30 and illuminating part 20 scatter to the relative Part I of photometric measurer 30 by light penetrating panel 10 determines final outside light intensity.That is, through type (7) can calculate illuminating part 20 scatters to the relative Part I of photometric measurer 30 arrival light intensity In by light penetrating panel 10, be appreciated that this arrival light intensity In is light intensity invalid in total light intensity of recording of photometric measurer 30, then photometric measurer 30 deducts this invalid light intensity In by the total light intensity Ic recorded and obtains final external environment condition light intensity, namely determines final outside light intensity Iw by following formula:
