There were high-power LED lamps that have phosphor is printed on the inside the flask. I have studied and tested a new generation of lamps.
Conventional LED lamps using white LEDs or COB-assembly, in which the LEDs luminous blue light, coated with a chemical - a phosphor that converts blue light into white.
In lamps Uniel Profi phosphor inflicted not on the LEDs, and the lamp bulb. In this technique has several advantages:
- phosphor does not fade from heat and lights are much longer without a change of color characteristics;
- lamps have a higher efficiency.
technology minus that of the phosphor takes much longer, and he nedoshev.
Uniel Profi lamps designed for illumination of industrial premises, warehouses, and other facilities that require powerful light sources.
I tested all four lamp series Uniel Profi:
LED-MP200-50W-4000K-E27-PH ALP06WH - 50W, 6500 lm, cap E27, color temperature of 4000K;
LED-MP200-50W-6000K-E27-PH ALP06WH - 50W, 6500 lm, cap E27, color temperature of 6000K;
LED-MP200-80W-4000K-E40-PH ALP06WH - 80 W 10000 lm, cap the E40, color temperature of 4000K;
LED-MP200-80W-6000K-E40-PH ALP06WH - 80 W 10000 lm, cap the E40, color temperature of 6000K.
Conventional light bulbs in the photo will help assess the impressive dimensions of powerful lamps.
Luminous flux, color temperature and color rendering index are measured using and a two-meter integrating sphere spectrometer Instrument Systems CAS 140 CT, Power consumption and power factor measuring device GW Instek GPM-8212, pulsation device Uprtek MK350D. Before the measurements to stabilize the lamp parameters were heated for half an hour.
The results of measurement parameters 80-watt lamps.
Despite the fact that the actual power (75.1 and 76.3 watts) was slightly lower than specified, the luminous flux above statement - 10695 and 10715 lumens. The lamps have a very high efficiency - 142.4 and 140.4 lm / W.
The results of measurement parameters 50-watt lamps.
The actual capacity of a little less than stated - 45.4 and 45.7 W, the measured light output also turned out a little less than claimed - 6244 and 6296 lumens, but it is less only 3-4%, which is quite acceptable. The efficiency of 137.5 and 137.8 watts.
It is important for use in manufacturing to power factor (also known as power factor, also known as power factor) was high. At 80-watt bulbs it is 0.97 in 50-watt - 0.95. These are excellent results.
Pulsation practically no light (50 watt lamps ripple less than 0.3%, 80-watt around 1%).
Color rendering index CRI (Ra) of 72.1-72.5. This is sufficient for industrial premises, where Ra standards should be higher than 70 (remember, desirable Ra of more than 80 for domestic lighting).
In the corporate online store manufacturer 50-watt lamps cost 2805 rubles, 80 watt - 4127 rubles.
Through the use of technology of remote phosphor lamps Uniel Profi has a high efficiency and a longer service life compared to conventional LED lights. The manufacturer claims a life of 35,000 hours (four years of continuous operation), and unlike the majority of household lamps, it is quite real numbers. Moreover, it is possible that this design lamps last longer.
