I believe that everyone is familiar with advertising projection lamps. The application cases of advertising projection lamps in our lives are also relatively extensive, such as: projecting at the door of stores, projecting huge advertisements on exterior walls, projecting landmarks on landmarks, The above-mentioned projections can achieve the effects of advertising projection, brand promotion, new product release promotion, etc.; but the success of a projection advertisement is closely related to the brightness of the advertising projection lamp, so what are the factors that affect the brightness of the advertising projection lamp publicity pattern?

What are the factors that affect the brightness of the advertising projection lamp pattern?

 

Factors that affect the brightness of the advertising projection lamp pattern:

First, the power of the advertising projection lamp must be that the higher the power, the higher the brightness of the advertising projection lamp.

Second, the lamp beads of the advertising projection lamp, the higher the luminous rate of the lamp beads, the higher the brightness of the advertising projection lamp

Third, the transmittance of the advertising projection lamp, the higher the transmittance of the advertising projection lamp, the higher the brightness of the advertising projection lamp

In order to improve the brightness of advertising projection lamps, Ropard projection lamp manufacturers have made efforts in this regard:


The imaging part of the advertising projection lamp uses the convex lens imaging technology, but since our light source is not an ideal point light source, chromatic aberration and aberration problems will occur after being refracted by the convex lens, resulting in the image being not clear enough. In order to correct the chromatic aberration caused by the refraction of the lens, we use a specially made achromatic lens to replace the ordinary convex lens, so that the image is clear enough.

Generally, this problem is not obvious in projection lamps below 50W, because the light-emitting surface of low-power projection lamps is relatively small, which is close to the ideal point light source, but it is very obvious in high-power projection lamps. , mainly because the higher the power, the larger the light-emitting surface of the lamp bead, which is no longer an ideal point light source, resulting in prominent chromatic aberration and aberration problems. Many manufacturers do not use achromatic lens sets for cost and technical reasons.
