Flicker Free

 

---Definition and classification of strobe: strobe is a frequency of flickering, a cyclical repeating flash, including 2 kinds: eye-visible flicker /detected under stroboscopic instruments

 

---Causes of lighting strobe:

-----Supply voltage: signal of disturbance voltage

-----Product/systems: driver design (AC-DC, DC ripple, cost/size); dimming technology (cutting, PWM); Dimmer percentage

-----Lighting applications: relative state; environmental factors; personal factors

 

 

---Possible harms of lighting strobe:

-----Hazard to human health: headache, migraine, tiredness, increased intraocular pressure, blurred vision, lowered eye visual effect, attention distraction, neurological problems like photosensitive epilepsy

-----Safety related hazards: visual illusion or chaos like spinning machine; road lighting and auto lamp

-----Influence of interference on machines: camera, monitoring system, TV, scanning system (QR code)

Calculation methods of lighting strobe by IES (illuminating engineering society):

---percent flicker, FF( fluctuations depth MD) Micheison Contrast: value of 0-100%, many people accept it on wide use

---flicker index: Eastman and Campbell, value of 0-1.0

 

Requirements for lighting strobe:

 

In IEEE PAR 1789:2013, percent flicker ≤ frequency x 0.0008 / 2.5

Why us? Why not others?

1.Supplied by Kinglight - Top 3 LED packaging manufacturer in China,

equipped with world-advanced 800 LED packaging auto lines, high quality chip

2. 99.99% golden wire in led chip and copper holder to make the LEDs, gold has the best ductility, won't break when heat changes

3. Long lifespan, slow light decay, LM 80 approved

4. Our LED load is about 37%, very low, to prolong life span, lumen maintenance is high over time

for example, for panel 40W, 1000mA,

---use 204pcs 4014 SMD LEDs,0.5w/LED

If=160mA (forward current).12 Serial, 17 Parallel,

I =1000mA/17=58.8mA,

LED working load is 58.8/160=37%

1. Supplied by small LED packaging factory or big factory for low end market who use cheap chips which are not famous brand

2. Use alloy wire and iron holder to make LEDs, alloy has poor ductility, may get broken when heat changes, which makes LED defective

3. Short lifespan, fast light decay.

4. LED load is 63~104%, fast lumen decay.

for example, for panel 40w, 1000mA

---use 120pcs 2835 LEDs, 0.5w/LED

If=160mA (forward current), 12 Serial, 10 Parallel

I=1000mA/10=100mA

LED working load=100/160=63%

---or use 192pcs 2835 LEDs 0.2w/LED

If=60mA (forward current), 12 serial16 parallel

I=1000mA/16=62.5mA,

LED working load is 62.5/60=104%
