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.
LED
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.

What ways can see LED street lights to replace the high pressure sodium lamp?

Image
Under the condition of current technology,luminous efficiency of  LED street lamp  is more than high pressure sodium lamp, it is an indisputable fact that TEK LED street lamp can reach 160 LM/W. And HPS spectrum is concentrated in the yellow area, its color temperature is low, only 2000-2500 k, and relatively high color temperature such as LED, LED street light natural white temperature of 4000-5000 k, cold white is 5000-6500 k. At the same time compared with HPS, LED street lamp with high color rendering index, close to natural light in the actual lighting, can bring a person the sense of comfort. Followed by "irradiation uniformity", although the  LED street lamp  lighting is relatively concentrated, but can be by the light path of the second design, can make the light source of lamps and lanterns presents the ideal state, realize the reasonable light distribution curve adjustment, control the distribution of light, so a...

The advantage of new style TEK LED panel light is obvious

Image
TEK  LED panel light , continue to use the reflective surface luminous technology, light after secondary reflection through high light transmittance mask projection, reduce glare, the light is more soft and comfortable to the human eye to watch not easy fatigue, particularly for students who have long time exposure to indoor lighting lighting, subway passengers or office staff. The application of the patented reflective material ensures the reflection efficiency of the light, and the original high light effect of the panel light is retained to the maximum extent. In order to guarantee the reliability of the use,   the design principle of TEK LED panel light  adhering to the "maintenance", improve heat dissipation performance, reduce the LED light failure of lights and lanterns, significantly prolong the service life of the lights and lanterns, saving the maintenance cost of lights and lanterns. TEK LED panel light is more intelligent TEK LED panel light c...

Safe travel: TEK LED high bay light illuminate the locomotive base

Image
In recent years, China's rail transportation has been developing rapidly, and many second and third-tier cities have made great efforts to build urban subway projects, which have brought convenience to people.Subway passenger traffic is large, the operation security is always the top priority, the metro management department attaches great importance to the security of the train, and TEK LED high bay light  illuminate the locomotive base, which facilitates the maintenance and maintenance of subway vehicles. Traditional lighting there exists large droop, short service life, the problem such as glare, can't use how long will be replaced, is not only the economy, and the human eye in this light, easy to produce fatigue, especially the night repair subway locomotive, a bit not careful see not clear parts fault, cause hidden trouble.Today, many subway lines use LED high bay lights , which make lighting more efficient and more efficient.Second, can improve work efficiency, the ligh...
