Multiple Light Distribution Options
Street light should fit with a wide range of applications, such as highway, express way, roadway, avenue, walking path or parking lot lightings.
Considering this, ZGSM provides different light distribution lens for the K Series street light to achieve best lighting effect in different applications.
ZGSM follows the North American IESNA standard in providing the optional lens width ,TypeI, Type II and Type III.
Type I is suitable for walking path with 1 lane, Type II is for 2 lanes and Type III is for even more wider road.
ZGSM selects the most suitable lens for its customers according to the detailed parameters project by project.
TYPE I
The Type I lens of ZGSM K series street light has beam angle of 50*160 degrees.
In the IESNA Standard, The Type I distribution is great for lighting walkways,
paths and sidewalks. It is generally applicable to where the mounting height is
approximately equal to the roadway width.
TYPE II
The Type II lens of ZGSM K series street light has beam angle of 65*155 degrees.
In the IESNA Standard, the Type II distribution is used for wide walkways, on ramps
and entrance roadways, as well as other long, narrow lighting. It is generally
applicable to where the width of the roadway does not exceed 1.75 times the
designed mounting height.
TYPEII BLS
The Type II BLS is a new light distribution developed based on Type II.
BLS means back light shield. The light on the back of pole be reduced and the light
in front of the pole be increased accordingly. It is generally applicable to where no
need or need less light on the back of pole, such as residential area, high way,
bridge and etc.
TYPE III
The Type III lens of ZGSM K series street light has beam angle of 80*160 degrees.
In the IESNA Standard, the Type III distribution is meant for roadway lighting,
general parking areas and other areas where a larger area of lighting is required.
This distribution is intended for luminaires mounted at or near the side of medium
width roadways or areas, where the width of the roadway or area does not exceed
2.75 times the mounting height.
