What is the influence of the projection distance of advertising projection lamps? How to calculate the projection distance of advertising projection lamps? To understand how to calculate the projection distance, you need to understand the advertising projection first. Some influencing factors of lamp projection distance:

First, the power of advertising projection lamp products is a very important factor affecting the projection distance. The higher the power, the farther the projection distance is. Generally, under the same environment, 15-25w advertising projector lamp products and 50w-100w advertising projection lamps compared with the projection distance of the product, the difference will be more than double. The projection distance difference ratio here refers to the premise of not affecting the projection effect, that is, the effect should be consistent.

Second, the time period is also an important factor affecting the projection distance of advertising projection lamp products, that is, morning, noon, afternoon, and evening. Among them, the projection distance of advertising projection lamp products of the same power is the farthest at night, and at noon That is, when the sun is in the head, the projection distance is basically very short. This phenomenon occurs because the light of the sun during the day will overlap with the light projected by the advertising projection lamp, which will cause loss of light, resulting in the loss of light. , the pattern cannot be displayed.

Third, the environment used will also affect the projection distance of the advertising projection lamp. If it is used in a colorful light and color environment, there is a certain gap between the projection distance used in a dark environment and the dark environment. The next use is able to project farther.

How to choose the advertising projection lamp products suitable for your own projection distance?

When we purchase advertising projection lamp products, in order to purchase advertising projection lamp products suitable for our own projection distance, we need to truthfully inform the manufacturer of advertising projection lamps of our actual projection distance and projection environment period. Personnel, the staff of the advertising projection lamp manufacturer will design a projection scheme for you according to the actual situation, and then select a suitable power projection lamp product to recommend to you. Generally, in order to achieve better effect, the recommended advertising projection lamp product power It will be a little larger than the power of the standard power projector lamp products.
