With the application of [UVLED light curing machine] more and more extensive, many industries began to use UVLED light curing machine. New customers of UVLED will be unfamiliar with some commonly used equipment terms and units, and may bring some inconvenience when communicating with UVLED light curing machine manufacturers. As an enterprise with many years of research and development and production experience in the UVLED optical curing machine industry, the small edition of Koinu Precision Optoelectronics will introduce some common terms and units in the UVLED industry today.
Common terms and units are introduced
1. Luminous flux φ : the total amount of light emitted per second by the luminous body. Unit: lumen (Lm), representing the amount of light emitted by the luminous body. The more luminous the light, the more lumens there are. Usually the luminous flux is a UVLED lamp bead, and the chip manufacturer is used to measure the luminous efficiency of the lamp bead.
2. Brightness L: The unit solid Angle luminous flux per unit area of the luminous body in a specific direction. Unit: Nit (mcd). For example, an LED that emits light at a 60 degree Angle is in a 60 degree cone luminous flux.
3. Lighting effect: The ability of an electric light source to convert electrical energy into light, expressed as luminous flux divided by power consumption. Unit: lumens per watt (Lm/w).
The UVLED industry is usually called the photoelectric conversion rate, and the photoelectric conversion efficiency of the UVLED light curing machine is usually between 5% and 20%.
4. Life: Taking into account the damage of the UVLED light curing machine and the attenuation of the beam output, the output of the integrated beam is reduced to a specific number of hours. Typically, the initial light source is 70%.
5. Light intensity I: The light emitted by the luminous body per unit of solid Angle luminous flux in a specific direction. Unit: Candela (cd).
6. Illuminance E: The unit area luminous flux of the illuminated object illuminated by the light source. Unit: Lux = lumens Lm/ area m2. Of course, the power measurement unit is usually used in the UVLED light curing machine industry: mW/cm2. The light intensity, irradiance and intensity mentioned in the general industry all refer to illuminance.
