Luminous distribution types and advantages and disadvantages of road lighting

There are usually several types of luminous distribution for road lighting: symmetric light type, asymmetric light type, annular light type, trapezoidal light type, rectangular light type, etc. Among them, symmetrical light type refers to the symmetrical distribution of the light of the lamp on the horizontal plane, suitable for roads with relatively small widths; Asymmetric light type refers to the asymmetric distribution of light from a lamp on the horizontal plane, suitable for roads with relatively large widths; Circular light type refers to the circular distribution of light from a lamp on a horizontal plane, suitable for intersections and other places; Trapezoidal light type refers to the distribution of light from a lamp in a trapezoidal shape on a horizontal plane, suitable for use in places such as highways; Rectangular light pattern refers to the rectangular distribution of light from a lamp on a horizontal plane, suitable for places such as squares.

The following is a detailed description of various types of luminescence distribution:

1. Symmetrical light type: The light of the lamp exhibits a symmetrical distribution on the horizontal plane, suitable for roads with relatively small widths. The advantage of this type of luminous distribution is that the illumination is uniform, while the disadvantage is that the illumination range is small.

2. Asymmetric light type: The light of the lamp exhibits an asymmetric distribution on the horizontal plane, suitable for roads with relatively large widths. The advantage of this type of luminous distribution is its wide illumination range, while the disadvantage is that the illumination is not uniform enough.

3. Circular light type: The light of the lamp presents a circular distribution on the horizontal plane, suitable for intersections and other places. The advantage of this type of luminous distribution is its wide illumination range, while the disadvantage is that the illumination is not uniform enough.

4. Trapezoidal light type: The light of the lamp presents a trapezoidal distribution on the horizontal plane, suitable for places such as highways. The advantage of this type of luminous distribution is its wide illumination range, while the disadvantage is that the illumination is not uniform enough.

5. Rectangular light type: The light of the lamp presents a rectangular distribution on the horizontal plane, suitable for places such as squares. The advantage of this type of luminous distribution is that the illumination is uniform, while the disadvantage is that the illumination range is small.

In short, selecting the appropriate type of luminous distribution can improve the effectiveness of road lighting and make driving safer.
