How much do you know about high quality LED high bay light ? (2)
Article is from the efficiency of lamps and lanterns, glare and stroboscopic, lighting the safety of the big four aspects to explain the industrial lighting lamps and lanterns of the high standards of quality, now TEK will lead you from lighting energy saving indicators continue to explain for everybody inspection LED high bay light quality standards.
5, Energy saving index
The highest state of illumination is visual aesthetics, in order to enjoy the beauty, but if power consumption is too high, let users because of the electricity produced psychological burden, cause visual aesthetic feeling down, thus indirectly lower the quality of the lighting, so we put the lighting energy saving is also included in the lighting quality indicators.
Related to lighting energy saving target: light emitting efficiency, efficiency of lamps and lanterns, lighting the space effect of the rationality of the design and lighting space illumination value, driving power supply of the power supply efficiency, LED light source of the heat dissipation performance.
We focus on the efficiency of light source power supply. For LED light source, the efficiency of power supply is higher, and the luminous efficiency of the light source is higher and the light source is more energy saving.
The power factor of power efficiency and power supply is two different concepts, both of which are high, indicating the quality of power supply.
Power efficiency:
Driving power source is the input of the ac conversion to light the LED chip conversion device, in the process of the transformation, the conversion device itself will be a power loss, the loss is bigger, the lower efficiency of drive power supply, light source, energy saving index is low, usually drive power efficiency between 82% and 92%.
That is to say, the switching device of the electric power is the source power of between 18% and 8%, many of the LED light source tagging is the power factor of driving power, the annotation may produce an error, think that the higher the power factor, the more light energy.
In fact, the power factor of driving power supply affects only the loss of the power supply line, has no effect on energy saving light source itself, for small power LED high bay light, low power factor of power supply circuit of power loss is negligible.
For high-quality LED high bay lights, it is more important to drive the efficiency of the power supply. Of course, the power supply efficiency and power factor are both high and the power performance is better.
Power factor:
LED high bay light in the total power needed for the work, some are not light energy consumption, and was sent back to power grid, these have no loss of power, the power factor is lower, these power only increase wire line loss in power lines, power does not affect the light itself, records of electricity meters of line loss due to the low power factor is not sensitive, and the power supply enterprise is to pay for this part of the loss.
Therefore, the national standard also provides for the power factor of the high power LED high bay lights. The high power factor lighting source, the quality of the power supply is also expected. The power factor that drives the power supply is a completely different concept than the power factor that drives the power supply.
The purpose of this article is to make the buyers can easily learn how to buy products that meet the lighting quality knowledge, through the above index assessment, lighting source of purchasing is to ensure that procurement to products with quality guarantee.
