Basic introduction

LED light source is used in the field of lighting because of its low energy consumption and high light efficiency. With the development of technology, this kind of lighting is arranged in multi section users. Lamps and lanterns highlight the advantages of energy saving and have a long service life. This kind of lamps and lanterns can be widely used in all kinds of environmental lighting because of its high variability of light color, flexible use of light distribution and unique advantages of energy saving. It is also because of the direct light characteristics of LED light source that how to design scientific and reasonable light distribution on lamps and lanterns is very important. The luminescent characteristics of lamps are closely related to the lighting source, light transmission, reflection and various dimming accessories, which has a great impact on the final light distribution curve of lamps. The selection of LED as a new light source cannot be separated from the selection of light distribution curve.

Technical characteristics

The spatial light intensity distribution curve, light intensity data, regional luminous flux, lamp efficiency, luminance distribution, utilization coefficient and luminance limit curve of lamps are measured. Glare level, estimated curve, large allowable distance ratio, effective luminous angle, upper luminous flux, luminous flux, illuminance curve, light intensity curve and other photometric parameters.
