The working principle of gobo projector
The gobo projector light which use the principle of convex lens imaging.when the distance between 1x to 2x from the object to the convex lens and become an inverted or enlarged image. When the convex lens is a real image, the closer to the convex lens with the object, the larger with the image. The farther away, the smaller the image is. Therefore, if you want to make the image bigger, you should move the gobo closer to the lens.
However, the distance also changes. If the distance between the lens and the projection position is not changed accordingly, the projection image will be blurred, Follow the pattern of convex lens imaging. when the distance decreases, the image becomes larger.
How to choose right gobo lights
For the projection effect cannot be reflect via lamp power. Some suppliers will misguide the customer and told them it can be projection brightness images if use high power lamp. It is mistake. As projection pattern is the optical imaging.
It must include the power, optical block, image optical lens like this system can be reached the best configuration and projection the best quality images. So for the projection effect, it is not only ask the power lamp, but ask what is the projection Lux.
How to calculate the light effect parameters of gobo projector
That means if the photosynthetic efficiency is more high , the electric energy of gobo light transform optical energy more strong. It will be more energy-saving if with high of photosynthetic efficiency in the brightness.
Some of gobo lights suppliers only advertise the high power of gobo light. However, if the luminous efficiency is relatively low, then the brightness is relatively small,That is why we emphasize different manufactures with different brightness of the same power. Therefore, The customers should pay more attention to this parameter of light efficiency when purchasing the gobo projector. When high power, high light efficiency, brightness is great.
