Type of light source:
1,NDLS = Non-directional
DLS = Directional ("Directional Light Source" means a light source having at least 80% of total luminous flux within a solid angle of π sr (corresponding to a cone with angle of 120⁰)
2,MLS = Mains
NMLS = Non-mains ("Mains Light Source" means a light source that can be operated directly on the electricity supply of 230 (±10%) volt of alternating current at 50 Hz)
General product parameters:
1,Useful luminous flux:In fiche will be shown together with beam angle:
[value] in [Sphere (360°)/Wide cone (120°)/Narrow cone (90°)]
2,Beam angle correspondence: List of beam angle correspondences to Luminous Flux measurement:
- SPHERE_360: Sphere (360°)
- WIDE_CONE_120: Wide cone (120°)
- NARROW_CONE_90: Narrow cone (90°)
3,Voltage and current: LED bulb lamp is very important basic parameters. Commonly used voltages are 12V, 110V and 220V. Current is divided into input current and lamp bead current. The input current can be tested with the power supply, different power is not the same, according to the instrument.
4,Light effect: It is an important factor of LED bulb lamp. The pearl effect of the chip lamp is generally about 150-0lm /W.
5,Light flux: Light flux is mainly determined by the light efficiency and power of the LED bulb, which is generally measured by integrating sphere.
6,Light failure: How much the brightness of an LED decreases after a certain period of use. Heat dissipation and current are the most important factors affecting LED lighting failure. The current is not stable, the heat dissipation effect is poor, the light decline will be very serious.
7,Color rendering: the degree of color rendering of the light source to the object itself is called color rendering, that is, the degree of color fidelity; The color rendering of the light source is indicated by the color rendering index, which indicates the color deviation of the object under the light compared with the reference light (sunlight) illumination, and can reflect the color characteristics of the light source more comprehensively.
8,Glare: The object with very high brightness or strong brightness contrast in the field of vision can cause visual discomfort called glare, glare is an important factor affecting lighting quality.
