FAQ

Does anyone know the principle of the four star projection light of the adult science?
3 modes: the lights inside the projection lenses in different position, adjust to different modes can let the stars in different positions, so as to form the seasons
How is the light projection made out of Photoshop?
10".Select the "gradient fill" tool in the toolbar, fill in the white, and set the edge of the gradient to 60%, and then drag to fill in the selection. Then change the selection according to "Ctrl+T", and the effect is as follows:Next, we add some smoke effects to the projection lamp. Create a new layer, select the lasso tool in the toolbar, create a selection near the projection light, and set the feathering radius to 30". Use the default background color and foreground color, then execute Filter > render > cloud".Then set the layer blending mode to "color dodge" and fill "40%"".Next, the character appeared! Import a character picture. Place it below the beam layer and adjust its size. The final effect is shown in fig.:
Do not adults of science, do not suggest that I buy online, a bit more detailed ~!
With night light, outside of their own design
The effect is dynamic, and the fish can swim.People through the projection range, the screen will appear corrugated, this is related to the light, or with the set of lights into the file related to, and the file Related words, what format files do you need?
The projector is dynamic rather than static. Then you don't see a camera here? It's not the projector problem. It's the camera. Someone came in.
How does the projector light the picture?
Advertising is the use of LOGO projection lamp optical projection principle, using high brightness light source,
LED how far is the new light source projecting from the projection bulb?
Why LED, laser and xenon lamp at present it is difficult to shake the halogen lamp and UHEUHP lighting the main position? This also and its luminescence characteristics are not unrelated. Xenon lamp and halogen lamp in the car industry competition has shown a personality difference, although xenon lamp performance is good, but can be successfully transplanted to the projector light source, it is still hard to say, currently on the market using xenon lamp projector technology represented by SONY VW200, but its price is high level; laser technology was should be optimistic about whether brightness purity is "perfect", but today Microvision SHOW projector miss, let us begin to have a trace of worry, laser technology also temporarily stranded. As for the LED light source, it has become the most concerned technology at present. Whether it can break through its brightness bottleneck will be the key to whether it can become the mainstream. However, there is one point to note here, which is the color selection of light sources. At present, the projector light source is the basic source of white light, the color wheel or splitting technology to obtain a monochromatic light source is needed, 3LCD is the three chip and display RGB color image, the lens magnification before the image superimposed color effect; and the technique of DLP is used to color light, the color wheel is a few to be able to obtain the corresponding color number (except repeat). Now, laser and LED technology are expected to provide pure monochromatic light source directly, which will have a significant impact on the light path design of the projector, and even change the technical line and market pattern of DLP and 3LCD. The true monochromatic light source can give the projector technical promotion, how much for different projection technology, the light source technology is to close the technical gap of the two or to make it more distinctive, we wait and see.
Where can I get the star projection lamp in Shanghai? It's better to get there on the subway
ShangHai Railway Station: the mall can go there to see a lot of thingsThere's Metro Line 1
Why do some projection lights go on and not immediately?
The gas needs tens of thousands of volts voltage to trigger discharge, and we have no ballast starting function this ultra-high pressure,
