Led Lighting Sok Standard Terminology
Wavelength: The Change In The Color Of Light Can Be Described By Data. This Data Is Called Wavelength. The Wavelength Of Light We Can See Ranges From 380 To 780 Nm In Nanometers (nm).
Brightness: Brightness Refers To The Degree Of Lightness And Darkness Of An Object. It Is Defined As The Luminous Intensity Per Unit Area In Nits.
Light Intensity: Refers To The Brightness Of The Light Source, That Is, The Physical Quantity Of The Visible Light Radiation Emitted By The Light Source In A Certain Direction And Range, Unit: Candle Light (cd).
Luminous Flux: The Sum Of The Amount Of Visible Light Emitted By A Light Source Per Second In Units Of Lumens (lm).
Light Efficiency: The Luminous Flux Emitted By The Light Source Is Divided By The Power Of The Light Source, Which Is An Important Indicator To Measure The Energy Saving Of The Light Source. Unit: Lumen Per Watt (lm/w).
Color Rendering: The Extent To Which The Light Source Presents The Object, Which Is The Degree Of Fidelity Of The Color, Is Usually Called The "color Rendering Index". The Indoor Color Rendering Property Is Usually Expressed As Ra And Expressed In Numerical Values. Ra100 Is The Color Rendering Property In Sunlight.
Color Temperature: When The Color Of The Light Emitted By The Light Source Is The Same As The Color Of The Radiation When The Black Body Emits Light At A Certain Temperature, The Temperature Of The Black Body Is Called The Color Temperature Of The Light Source, And Only The White Light Has The Color Temperature. Unit: Kelvin (k).
Glare: High Brightness Objects Or Strong Contrast In The Field Of Vision. The Resulting Visual Discomfort Is Called Glare. Glare Is An Important Factor Affecting Lighting Quality.
Synchronization: Two Or More Than Two Led Lamps Can Be Operated Normally In A Programmed Manner Within A Specified Time. Generally, They Refer To The Led Lamps Of The Internal Control Mode. Synchronization Is The Basic Requirement For The Led Lamps To Achieve Coordinated Changes.
Protection Class: Ip Protection Classifies The Luminaire According To Its Dustproof And Moisture-proof Characteristics. It Is Composed Of Two Numbers. The First Figure Represents The Level Of Dust Prevention And Foreign Object Intrusion Prevention (level 0-6). The Second Number Represents The Degree Of Protection Against Humidity And Water Intrusion Of The Lamps (0-8 Levels). The Larger The Number, The Higher The Degree Of Protection.
Photoperiod: Natural Or Artificial Light And Dark Cycles That Can Affect Biological Organisms.
Photometry: A Method Of Measuring The Amount Of Radiation Based On A Given Light Function, Such As V(λ) And V'(λ).
Light Intensity Distribution: Light Intensity Distribution Of Light Source Or Lamp In All Directions Of Space.
Light Intensity Chart (table): The Light Intensity Is Given By Polar Coordinates Or Graphs. The Values ??in The Table Are The Light Intensity Generated By The Light Source At Every 1000 Lumens. For The Asymmetric Distribution Of Light Intensity, The Light Intensity Distribution In The Two Different Planes Can Be Used To Represent The Light Intensity Distribution Of The Lamp.
