26watt 62x62cm for Hospital Lighting Square LED Panel Light High Efficiency On-ceiling Mounting 140 lm/w 3600lm 4000K

 

Anti-glare, UGR<19

 

We offer 2 options on UGR<19 diffusor: matt diffusor; rhombus diffusor

 

---Definition of UGR:

UGR is short for Unified Glare Rating, it measures psychological parameters of subjective discomfort to human eyes caused by light from lighting devices in indoors visual environment. Its value can be calculated by the regulation condition with CIE unified glare value formula

 

 

 

High Efficiency Square LED Panel Light 4000K 3600lm With Smooth Lighting

 

 

---UGR value gradation:

UGR is divided into 7 levels, namely 28, 25, 22, 19, 16, 13, 10

28 nearly unbearable glare value

25 discomfort value

22 nearly discomfort value

19 the boundary between comfort and discomfort

16 nearly acceptable glare value

13 nearly glare value

10 no glare value

There are two methods to reduce the glare that is present in relation to interior lighting: firstly, to use luminaires that are UGR<19 rated; secondly to ensure that the lighting design is appropriate for the environment they are being used in i.e. the correct number and position of luminaires.

 

Within an office setting, for the luminaire to be classified as “low glare” it must have a UGR below 19 at desk level. Anything above this may cause discomfort – this further enforces the need for high quality interior lighting that is rated UGR<19.

 

There are a number of different UGR limits that should not be exceeded in certain environments, these include:

 

UGR Rating

Environment

UGR ≤ 16 Technical drawing
UGR ≤ 19 Reading, writing, training, meetings, computer-based work
UGR ≤ 22 Craft and light industries
UGR ≤ 25 Heavy industry
UGR ≤ 28 Railway platforms, foyers

 


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.
