The technical parameters of LED components are pointers describing their electrical and optical properties.The following is a common technical parameter for LED components:
Voltage: The working voltage range of LED components.LED usually requires a specific voltage to work normally.
Current (Current): working current of LED components.The current determines the brightness and lighting effect of LED.
Power (Power): power consumption of LED components.The relationship between power and current and voltage is: power = voltage × current.
Luminous intensity: The strength of light emitted by LED components.Measured at the strength standard of a uniform light source, the unit is Candela.
Luminous Flux: LED component's total light energy emitted per second.It is expressed by lumen.
Luminous Effical: The light efficiency of LED components, the ratio of light flux to power.It is expressed in the units of lumen/watt.
Color Temperature: The color of light emitted by LED components.According to Kelvin as a unit, common color temperatures include warm white light, natural white light and cold white light.
Color Rendering Index: Index indicators to measure the real color ability of the LED component to restore the real color of the object.The commonly used color index is RA, and the range is from 0 to 100. The higher the value, the better the color restoration ability.
Viewing Angle: The angle range of the luminous angle of the LED component.Indicates the radiation angle of the light from the horizontal and vertical direction of LED.
Lifespan: The service life of LED components is usually calculated in hours.LED's life is affected by various factors, such as temperature and current.
These technical parameters are very important for selecting and applying LED components.When buying LED components, you can refer to the technical parameters to determine whether the component meets specific needs and make appropriate choices.
