Energy Saving Stable LED Flat Panel Light 60x120cm for Hospital 48watt In-ceiling Mounting Aluminum Frame

 

LGP (Temperature and humidity test)

At 40℃, in all the luminous zone, light emerge uniformly, No obvious visual difference

At 0℃, panel use PS light guide plate, in the middle of luminous zone, dark area appears

When temperature back to 2.31℃, dark area still exists in PS LGP; when back to 10℃, dark area disappears slowly

When temperature below 0℃, the panel use PS LGP appears dark area, bad user experience.

LGP (UV accelerated aging test, ISO 4892.3-2006 )

After UV test, panels using PS LGP turn yellowish,

Our panel using PMMA LGP still work well, good uniformity.

Panel use PS LGP, optical parameters like CCT and SDCM changed a lot, large lumen decay.

Potential risks, panel use PS LGP yellowing fast, especially when panel used in the room with sunshine, then lumen output will decrease and looks dark and ugly, non-uniform.

Why use PMMA LGP or PS LGP?

1. we use 4014(L40mm*W14mm) LEDs, then can match the light guide plate 3mm or 2.3mm perfectly. For luxury panel use 3mm PMMA before, and popular QT panel, use 2.3mm PMMA LGP now.

2. If using 2835(L35mm*W28mm) LEDs, then should use light guide plate 3mm at least and cost goes up

The LGP we use is silk printing by Japanese ink, Nagase brand, no drop after using 5years, panel uniformity is very good. If using normal PS material LGP, cheaper price, panel looks very vague and hazy when light up.

Comparison with others:

 

 

LED
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%

Remark: The way to test if the LEDs use copper holder or iron holder :

Use magnet, the LEDs which are on magnet use iron holder.
