How To Solve The Problem of Projection Size of The Gobo Projector ?

In the advertising projection light industry, one of the most troublesome issues for customers is the "significant discrepancy between the actual projection size and the expected size" - when they choose a 100W gobo light and install the projector pattern glass lens, the actual projection on-site is either too small to be seen clearly or too large with blurry edges, which even affects the dissemination effect of the brand image.

Last week, we received an urgent email from our British client Mark. He had customized a wall-mounted projection advertisement for a local chain café. The original requirement was for a projection diameter of 3.5 meters, but after installation, it was only 2.1 meters. The projection image was too small, and the café about to open was in a state of panic.

Step 1: Break down the problem and determine the installation distance for the customer's gobo projector

Many people believe that the size of the projection is only related to the installation distance. However, this is not the case. Our technical team immediately connected with Mark via video call and discovered that the core issue lies in three details:

• Equipment installation distance: The customer installed the lamp at a position 6.5 meters away. However, due to the layout of the scene, the farthest installation distance is 6.5 meters and it is a fixed distance.

• Lens model: The customer chose a standard lens. However, at a diameter of 3.5 meters and a height of 6.5 meters, a wide-angle lens is required (the projection ratio parameters of different lenses directly affect the size. Normally, the standard lens ratio is 1:0.32).

• Environmental lighting: The café has strong natural light during the day. The original equipment's brightness is insufficient to support a large-sized projection (brightness and size need to be proportionally matched).

Step 2: Quick solution, allowing customers to see the results on the same day

Without any further excuses, we presented two sets of solutions on the same day.

1. Projection lens adjustment: Replace the wide-angle lens for the customer and guide them to finely adjust the installation height to 3.5 meters (calculated using the projection ratio formula, 6.5-meter height + 13° (1:0.52) wide-angle lens precisely projects a 3.5-meter diameter).

2. Projector focusing: Provide remote assistance to the customer to adjust the projector focus, so as to make the projection effect image clearer.

The next day, Mark sent a live video: The brand logo projected on the wall of the café was just the right size, with sharp edges and the texture of the pattern clearly visible. In the email, he said: "Not only did you solve the problem, but you also made me understand that choosing a projector is not just about buying equipment, but rather buying a 'visual solution'."

Step 3: Transform individual cases into standards, enabling more customers to avoid unnecessary detours.

After this incident, we immediately updated the "Gobo Projector Lens Selection Guide", adding a "Projection Size Calculation" page - customers only need to refer to the installation height, different angles of the gobo projector lenses, and the desired size, and they can easily know how to choose the correct projector lens, avoiding the problem of "inconsistent size" from happening again.

In fact, after years of doing foreign trade, we have come to understand that what customers purchase is never just "a gobo light", but "how to make the brand shine in the scene". From equipment selection to installation and placement, every meticulous detail is aimed at ensuring that the brand image presented by the customer can be displayed in the most perfect size before the audience.

If you are also troubled by the size, clarity and scene adaptation of the advertising projection, please feel free to message me - we not only provide the equipment, but also offer a solution to "make the projection picture just right".
