How is the glass gobo of the projector lamp made?
The projector lamp is the use of optical projection principle, the use of high-brightness light source, Project the design on the logo light panel onto the wall or floor of the building, forming a visually impactful image display and advertising effect. As well as novel and special media forms and dynamic visual effects, it can attract the attention of consumers.
Projection lights are everywhere, and they can be seen in shopping malls, hotels, KTVs and many other places. The trendy and avant-garde projection lamp, the projection screen is clearly visible, all of which attract passers-by. But do you know how the projector patterns you see are made? Let's let the editor take you to understand!
The material of the pattern piece can be divided into film piece, iron piece and glass piece.
1. Use film to make patterns. Film is printed with ink, which is organic and not resistant to high temperatures. It is easy to decompose and change color under strong light and high temperature, while the projection lamp has strong light and will produce high temperature in the process of use, that is to say, it is used in lamps and lanterns under high temperature and strong light. After oxidation and discoloration, it is easy to make the color on the film fade, and the color of the projected pattern may fade immediately in a few days, so it is inconvenient to replace it frequently.
2. Use iron sheetsAlthough the temperature resistance of iron sheet is better than that of film and glass film, it is better to make gobosYou can't make complex pictures, you can only make themBlack and white. It doesn't work out very well!
3. The glass sheet is made of gobo, and the glass piece we choose by gobomake.com is made of high-temperature coated glass, the surface is inorganic, and the pattern will not fade for ten years. Even if the temperature of the lamp is high and strong, there is no need to worry about the pattern on the glass plate changing. The light transmittance of the glass sheet is more than 90%, the projection pattern outline is clear, the details can be clearly displayed, and the color is gorgeous.
Production process of pattern sheet of projection lamp
The designer's drawing is also exquisite, if the color and layout of the designer's drawing do not match, it will not only lead to the increase of the working hours of the film makers, but also lead to the unsatisfactory effect of the final projected pattern. Therefore, Gobomake.com's customer service will give customers suggestions for modification, and then let the designer design one-to-one according to the content required by the customer, in order to achieve the most ideal projection effect. After the designer designs the pattern, with the consent of the customer, we begin to make the lamp film for the customer.
First of all, the production department will check the CDR file pattern made by the designer, check whether there is any overlapping pattern and line, and then use the fill font black as the path to make the picture. Then the unwanted picture is eliminated, the useful part is retained, and then made on the light film, the gobo film production time is longer, the simplest picture production time is generally about half an hour, Complex graphics take four hours. The precision of making the light film picture should be high, and finally the picture is projected by the projection lamp.
For now gobomake.com according to the color, the gobo can be divided into monochrome film, two-color film, three-color film and four-color film and full-color film. Monochrome and two-color films are more conventional light films, mainly used for conventional logo projection, three-color and four-color films can basically meet most of the needs, and full-color films can make any pattern, such as portraits, landscapes, etc.
In addition, due to the reason of its own material, a gobo can only be monochrome, if you make a multi-color film, you need to make a separate piece of light for each color in the picture, and then overlap and glue the light pieces together to achieve a multi-color effect. After the production of the lamps is completed, our gobomake.com staff will perform a final inspection of the finished lamps to ensure that the pictures are clear, and install them on the projection lamps to check that the projection effect of each lamp is consistent with the pattern required by the customer.
In a word, when editor is learning to make glass gobo, the useless ones are much better than good ones. These professional things should be handed over to professional personnel to do, so as to save worry and trouble. Roppard projector lamp, your wise choice!
