What is the sensing distance and angle of solar outdoor post cap lights

What is induced distance and angle
The common intelligent control method of Solar Outdoor Post Cap Lights is to automatically turn on the light through human infrared sensing (PIR Sensor). Induction distance refers to the maximum range in which the sensor can detect movement of a human or object. The sensing angle refers to the horizontal coverage angle of the detection range. The two jointly determine the lighting coverage capacity of the lamps in courtyards, walkways, gardens and other places.

Common induction distance parameters
The sensing distance of Solar Outdoor Post Cap Lights is usually between 3 meters and 8 meters. Low-power or small sensor lamps are generally designed in a range of 3 to 5 meters and are suitable for smaller courtyards or close-range access. The induction distance of high-performance products can reach 7 to 8 meters, covering a larger range of active areas. Too short induction distance will lead to insufficient lighting range, while too long distances may be disturbed by small animals or external environment, so reasonable design is crucial.

Common induction angle parameters
The sensing angle of Solar Outdoor Post Cap Lights is usually between 90 degrees and 120 degrees. The standard design sensor covers an angle of 100 degrees, which can meet daily courtyard passage lighting. Some high-end products are equipped with wide-angle sensors, and the sensing angle can reach 120 degrees or even larger, which is suitable for open gardens and terraces. Although the coverage of the sensor with smaller angles is limited, it can reduce invalid triggers and improve energy usage efficiency.

Relationship between induction distance and lamp installation height
The installation height of Solar Outdoor Post Cap Lights is generally around 1 meter to 1.5 meters on the top of the cylinder. The installation height directly affects the induction performance. When the height is low, the sensing distance will be shortened and the angle range will be limited. When the height is moderate, the sensor can capture human movements on a large scale. If the installation is too high, a detection blind spot may occur. Therefore, when designing and installing, product induction parameters need to be reasonably selected based on the courtyard environment and cylinder height.

Relationship between induction angle and courtyard layout
In a narrow walkway or fenced passage environment, the 90-degree sensing angle Solar Outdoor Post Cap Lights is enough to cover the main walking direction. In wide courtyards or corner areas, 120-degree induction light fixtures can provide greater lighting ranges to avoid lighting blind spots. The choice of different angles requires combining the user's courtyard layout to ensure the balance between induction coverage and lighting effects.

The impact of induction performance on energy-saving effect
Efficient induction distance and angle design can reduce ineffective lighting and improve power utilization. Solar Outdoor Post Cap Lights usually adopts the "people come and light up, and people leave and die" mode. If the sensing range is too large, it may cause frequent triggering and increase battery consumption. If the range is too small, it may not be lit in time when someone is active. Reasonable distance and angle can achieve a balance between energy saving and comfort, extending the lighting time.

The influence of environmental factors on induction performance
The induction performance of Solar Outdoor Post Cap Lights is affected by temperature, humidity and obstacles. In high temperature environments, the temperature difference between the human body and the environment decreases, and the induction distance may decrease. In rainy and foggy weather, the infrared signal will be partially blocked and the sensing sensitivity will be reduced. In environments with walls and plants, the angle coverage will also be limited. Therefore, in practical applications, it is necessary to comprehensively consider the impact of environmental conditions on induction effects.
