The peak luminous efficiency of 5.6cd/A(3.9lm/W) was achieved at 0.1mA/cm~2 and maximum brightness of 5100cd/m~2 was obtained at 15V.The performances of this diode can meet the request of white light based on illumination.
The following-float voltage technique is used to design the electronic circuit,to insure that the operating voltage of several series LEDs will be between 2V and 200V.The constant current drift is than smaller 5μA/℃ at the output of constant current of 10~500mA,which meet the demend of the every kindred of LED power supply designing in illuminating engineering.
The design,composition,working principle,function,experiment and teaching effect of self-developed teaching adn experiment device of building power supply and illuminating system are analysed in the paper.
A new method of determinating the Talbot distance under ideal illuminate condition was intruduced,and two method of calculating the Talbot distance under unidael illuminate condition was given in this paper.
The running results show that the proposed algorithm can consistently yield high-quality mosaics, even in the cases of poor or differential lighting conditions, existences of minor rotations, and other complicated displacements between images.
The lighting problem for this class is solved, thus generalizing earlier results for zonohedrons (H.Martini) and zonoids (V.
The pattern of luminance waves in thin-film electroluminescent structures was modeled and the duration of transient lighting processes in these systems was determined.
A candle was lighting… (In memory of Mikhail Semenovich Mesezhnikov)
It has been tested using many photos of various ethnic groups under various lighting conditions, such as different light source, high light and shadow.
But when it was irradiated under UV illumination or solar irradiation for some time, the catalyst could be reused without loss of catalytic activity.
For three tested samples, under UV illumination CCT01 has the highest activity for MB photocatalytic degradation, while in the case of RB, CCT02 is the most active photocatalyst.
Under visible light illumination, CCT005 has the highest activity for both MB and RB photocatalytic degradation.
After treatment of the mycelium with 5-azacytidine, the protoperithecia formation was accompanied by inversely proportional changes in the formation of conidia, both in the dark and after illumination.
A New Type of Adaptation of the Cyanobacterium Spirulina platensis to Illumination Conditions
According to the reflectivity of the object, one of the illuminating methods-straight illuminating or inclined illuminating-is adopted.
Experimental study of the features of the method for illuminating the surface of a tested object for measuring displacements wit
The action potential was generated by illuminating the plant sample for a few seconds.
It is demonstrated that, with the use of an external "illuminating" field (of thermal origin or generated artificially), it is possible to separately reconstruct the distributions of all aforementioned parameters.
It is due to the hyperfine interaction of nuclei with excitons whose spin polarization is artificially maintained at zero (by illuminating with unpolarized light) but for which nonequilibrium alignment occurs.
