Pattern film, also called LOGO film and GOBO film, can be placed in pattern projection lamp or LOGO lamp to project patterns into patterns.
The material of the pattern sheet can be film, iron sheet and glass sheet.
The film is simple to make and has a short life, but it has poor light transmittance and low contrast, is not suitable for high temperature, is easy to fade and is frequently replaced.
Iron can't make a complicated picture, it can only be black and white. The effect is not very good.
The pattern piece of glass is made of high-density glass, with inorganic surface, high temperature resistance, long-lasting colorfastness, light transmittance of over 90%, clear outline, and very fine graphics can be made.
The pattern film of Le Di photoelectric projection lamp can be divided into monochromatic film, bichromatic film, trichromatic film and panchromatic film according to color. Wherein the dichroic film and the trichromatic film are formed by overlapping a plurality of monochromatic films.
Monochrome films are mostly in the form of LOGO, and some complex logos are multicolored, which can show full-color effect well and can be made into any patterns, such as portraits, location, photos and so on.
The pattern can be any geometric figure, and the content can be a paragraph of text, calligraphy, ancient poems or exquisite patterns, which can play an extraordinary role in different occasions.
