Q: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.:

Q: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.

Q:What are the advantages of outdoor projection lights?

(2) easy to make and installThe installation of the traditional light box is time-consuming and laborious, and consumes a lot of manpower and material resources, but it can not attract the sight of consumers for a long time. Dynamic projection advertising will help you save all the inconveniences and allow you to finish the tedious tasks in a short time.(3) flexible and convenient to changeAs every business owner knows, the traditional light boxes and billboards are very difficult to replace. Once a general advertisement is made, it is difficult to modify it. Even if the address and phone number are changed, such a small change, the entire ad must also be completely overturned, re produced, resulting in enormous waste of human property. And often can not quickly cater to the rapidly changing market, the rapid new concepts of enterprises, new products expressed to consumers. Le Di photoelectric logo projection advertising is the use of a large power projection equipment, using optical projection principle, using high brightness light source, the exterior wall of the negative color advertising content onto the high-rise buildings, outdoor advertising form a highly visual impact in the night. Its high arrival rate characteristics, as well as new special media forms, dynamic visual effects, can well attract the attention of consumers.

Q:What projection bulb is good. Where can I buy it?

Of course, LED bulbs, energy saving, environmental protection, and also have a protective effect on the eyes

Q: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).

Q:I want to sell the star projector, but I don't know where to buy it Can anyone tell me where to buy the goods? Is the quality good? Is the price all right? Thank you, ha!

Mine is pirated, genuine, do not know, to purchase channels, but also do not know, can only tell you the quality of general

Q:What are the common projection lights?

Would you like to ask about the light bulb of the projector? I know the classification of the lamp

Q:The scientific four seasons star projection lamp

Open the box, followed by manual assembly, in front of the box containing the accessories, you can open the above statement can be seen on constellations and celestial bodies of knowledge and installation guidelines are Chinese, quite interesting, illustrated on the very clear, with the Chinese introduced the assembly steps to teach you how to make other accessories, so that lights can automatically rotate and enhance the effect. All right.

Q:The light is on, the fan doesn't turn, the projection light doesn't work. Where is the trouble? Thank you

Motherboard damaged, this cottage machine quality is very poor, and later to buy real brand-name, such as BenQ, SONY, EPSON, good quality, with 10 years no problem, the effect of killing 1000000000 times the cottage machine!!The LED projector is completely rely on money [figure effect online bragging serious resort to deceit.]Why is the domestically produced LED projector only a short span of 1 years warranty?If the LED projector really lives long, why is the warranty only half the size of the brand-name product?Why is Japan's SONY, Matsushita, EPSON, Hitachi, BenQ Chinese, Acer projector is the world famous 2 year warranty,And domestic LED projector only a short 1 years warranty, and if the LED projector really long life, why is the warranty only half of brand-name products?Because of the poor quality of the actual domestic LED projector, low brightness is not clear, the failure rate is too high, not mature technology, poor quality parts, backward production facilities, backward technology, these small manufacturers did not dare 2 year warranty!!!These fully show that domestic LED projector small factory is very timid, very guilty, and no confidence in their products!!!Nuts, rice, the actual life of hongtianpao and so on all kinds of domestic LED projector 2000 to 3000 hours *************Nuts, rice, real life hongtianpao LED projector and so on 2000 to 3000 hours later, LED lights use 2000 to 3000 hours, the brightness will drop rapidly, absolutely not up to what tens of thousands of hours!!!

Q:What is the relationship between the power of projection lamp and luminous flux and luminous efficiency?

Start with a formula: light effect = total luminous flux / bulb power. From this formula, we can see that the higher the luminous efficiency is, the stronger the ability of the lighting equipment to convert electric energy into light energy, that is, the higher the light efficiency is, the more energy saving.At the same time, the above formula is deformed: total luminous flux = bulb power * luminous efficiency. That is, under the same power, the higher the light value, the greater the brightness.If some businesses only promote their projection lamp power is relatively large, but the light effect is relatively low, so the relative brightness is relatively small, which is why we have the same brightness power products from different manufacturers is not strengthConsistent cause. Therefore, customers in the purchase of recommended projector products, but also pay attention to light efficiency of this parameter.
