What does the magnification of solar floodlight mean?

There are two main understandings of the "magnification" of solar floodlights. The following is a detailed introduction:

Optical magnification

Definition:

Optical magnification refers to the ratio between the luminous Angle of the light source of the luminaire and the Angle of acceptance of the illumination target.

Calculation formula:

Optical magnification = receiving Angle of irradiation target ÷ Luminous Angle of light source.

Example description:

Assuming that the spot illuminated by the floodlight is 1 meter in diameter and 10 meters in distance, the irradiation Angle is arctan(0.5/10)=2.86°. If the light distribution Angle of the floodlight is 15°, the optical magnification is 15°÷2.86°=5.24 times.

Influencing factors and effects:

The higher the optical magnification, the more concentrated the light, the greater the light intensity, and the farther the irradiation distance.

High-power floodlights are often used in places that require remote irradiation and a small irradiation range, such as building facade floodlights in landscape lighting or key cultural relics lighting.

Panel ratio

In the application of solar floodlight, the "magnification" of the panel may also refer to the multiple of the charging efficiency or power output of the panel relative to standard conditions. This is related to the amount of electricity that the solar panel can produce under certain lighting conditions, which affects the overall performance and battery life of the floodlight.

Precautions and application selection

When purchasing solar floodlights, the appropriate magnification should be selected according to the actual application scenarios and needs.

High power lamps are suitable for long distance and small range of illumination tasks, while low power lamps are more suitable for close range and large range of illumination.

At the same time, it is also necessary to consider the efficiency of the panel and the compatibility of other components of the entire system to ensure stable and efficient lighting effects.

In summary, "magnification" has specific technical meaning and application value in the field of solar floodlight, which needs to be accurately understood and applied according to the specific context.
