Recently, some netizens asked how to mark the technical parameters of LED lights in lighting design.

Answer: In order to meet the needs of the project, at least the following parameters should be marked on the LED lamp:

Rating power Pe - the necessary parameter for calculating LPD value;

Rated input voltage Ue - an important technical index;

Rated input frequency f - important technical indicators;

Luminous flux is the key parameter for illumination calculation.

Relevant color temperature Tk - technical parameters related to site chroma and blue light;

The general color rendering index Ra is an important parameter for the place.

Special color rendering index R9 - an important parameter for the place;

Protection level IP - a very important parameter for outdoor, humid and dusty places.

The stroboscopic ratio or stroboscopic index is higher for places requiring high visual operation and HDTV broadcasting.

Life span - economic index.

The above parameters are the basic requirements. Users can adjust them appropriately according to the specific project (such as environmental temperature) to meet the needs of the project.
