Embodiment
Below in conjunction with accompanying drawing, the present invention is done further and explained.
As shown in Figure 1, a kind of optical switch device that can regulate continuously luminous flux, this device mainly utilizes electric moistening effect to finish the work, and device comprises upper substrate 11, infrabasal plate 12, sidewall 13 and filling liquid; Upper substrate 11 and infrabasal plate 12 are supported by sidewall 13, have formed a cavity, are full of filling liquid in cavity;
Filling liquid comprises the oil-based liquid 19 of the lighttight waterborne liquid 20 of polarity and nonpolar printing opacity, these two kinds of liquid unmixings.Waterborne liquid 20 is the lighttight polar liquid that water, salt solusion etc. obtain by dyeing; Oil-based liquid 19 is filled has expired other spaces except waterborne liquid 20 in cavity.
Common hydrophobic layer 17 is 110 ° with waterborne liquid 20 contact angles; Super-hydrophobic layer 18 is greater than 150 ° with waterborne liquid 20 contact angles.
Transparency conducting layer 15 is made by electrically conducting transparent material, has selected tin indium oxide in the present embodiment.
Bulge-structure 16 is transparent cake structures, and material can be selected dimethyl silicone polymer (PDMS) or light glass etc.
Super-hydrophobic layer 18 has high transparent, can be the micro nano structure that fluoropolymer is made, or utilizes fluoropolymer to carry out the common micro nano structure of finishing.This super-hydrophobic layer 18 is got rid of lighttight waterborne liquid 20 beyond the region covering in super-hydrophobic layer 18 effectively, and light source can appear by super-hydrophobic layer 18, can obtain initial luminous flux.By changing the size flexibly changing of super-hydrophobic layer 18, initially lead to light quantity.
Above-mentioned material is not limited to the material of enumerating, and can replace with intimate material.
As shown in Figure 2, when this device is when opening state, between sidewall 13 and electrode layer 15, apply the wetting signal that drives of electricity, the interface of waterborne liquid 20 and hydrophobic medium layer 14 can occur to increase constantly, thereby make waterborne liquid 20 occur to infiltrate constantly on hydrophobic medium layer 14 surface, in impregnation process, waterborne liquid 20 can move to sidewall direction gradually from common hydrophobic layer 17 surfaces, thereby make lighttight waterborne liquid 20 cover common hydrophobic layer 17 areas, continue to reduce, simultaneously transparent oil-based liquid 19 fill areas increase.
This process as shown in Figure 3, in figure from left to right, along with the effective area of lighttight waterborne liquid 20 continues to reduce, oil-based liquid 19 fill areas increase, luminous flux is continued to increase, reached can continuous setup luminous flux object, thereby realized the continuous adjusting to luminous flux size.There is not movably mechanical part in whole device, thereby has got rid of the defect of the device damage occurring because of mechanical part wearing and tearing, improved prior art.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
