The Retail LED lighting energy savings promotion road

Recently, the Commerce Department responsible person claimed that “the 12th Five-Year” period strive to build a large number of led lighting energy savings shopping malls, supermarkets and green hotels in the country. After the information spread out, the retail business of energy-efficiency road causing the concern again.

For labor,LED Street Light supermarket, power is the only way out of their savings. The reporter visited the site and found that energy saving has not only become the mantra of the retail business, but also to promote. Retail stores of LED lights in Dongguan city are not widespread.

Retail LED energy-saving promotion road

Retail LED energy-saving promotion road is difficult to this point, Kwong Chi-hung, fully understood.

Due to the broad prospects of the LED industry, three years ago, Nokia, Apple, Amazonand other companies OEM housing, Kwong Chi-hung, set up in DongguanJinyang energy technology company, specializing in the production of led lighting energy savings.

On the starting of set up, Kwong Chi-hung clearly recognize that small businesses can not get government projects, only the target in the commercial areas, the first is the retail business, the underground parking lot of the real estate business in these areas.

“Three blocks, stores, rents, wages, and lighting costs, lighting costs can be compressed. “Said Kwong Chi-hung.  The mall venue rental and labor costs have gone up every year and can not be lower down, but a cost of lighting by changing lighting facilities to compress the cost. Because the mall should be lights on, the overall cost of lighting is high, so this is where the stores must be cost-saving.

It is because of seeing that, Kwong Chi-hung start retail businesses to promote energy conservation.

The first companies to talk about cooperation Qing Town, local businesses, department stores Qing Town, Kwong Chi-hung, said that compared to traditional lights, LED lights put high cost in the fist time, therefore, in order to get each other’s trust, Kwong Chi-hung adopt free trial within half years to promote their minds, and then six months after, the stores all use LED projects energy saving lamps.

The effect of public praise get obvious, Fu Sheng boss Kwong Chi-hung, introduced the department stores in Shenzhen, Dongguan SPAR franchise owner. Kwong Chi-hung, soon reached an agreement of led lighting energy savings with these large-scale project.

voltage for led lights in led production

In the LED street light production, when we produce the chip package, the cup bubble occupies a large proportion, but the product in the production process if the bubble problem has not been a good solution or prevention, it will cause decay products a factor to accelerate the performance of IV to reduce the IR VF increased. So, any solutions for the existence of bubbles and plastic mixing full? Here we analyze from the few comments given by the people in the voltage for led lights industry.
voltage for led lights in led production
Factors affecting bubbles, but do some engineering assessments, can be solved led high bay step by step.  If there is a bubble cup, you can give a certain percentage of the plastic cup filling, and then proceeding to the next step process. The following relevant factors:
1. An environmental temperature and humidity had a greater influence on the bubble.
2. mold temperature is also generated a factor of the bubbles.
3. the formation of air bubbles and process adjustment.

For example, some factories there is no vacuum, no air bubbles, and even if the factories pumping vacuum bubbles, it should not be pumping vacuum. But the operating speed of skilled into a question of degree. And ambient temperature are also inseparable. Ambient temperature changes, we can take appropriate measures to control. If room temperature is 15 degrees, we must find ways to help glue the temperature reaches 60 degrees, so do the bubble cup should not occur again! Meanwhile, we should pay attention to many details in voltage for led lights. Such as tiny bubbles by eyes and subtle microscope can not see the drum pre-stick adhesive, but into the oven body, hot flatulence bubble expansion up.

Manually pre-Glue, brackets must be preheated. Preheat the pre-filling the AB material to swap the first two hours. As long as you keep the AB material, stents are hot bubble problem is not intractable. Encountered because of poor mobility, AB Cold, Cold bracket easily into the bubble. The operation should pay attention to the following question about voltage for led lights:
1. operating skills of the operator (the whole there are side air bubbles)
2. stick gum machine speed and the gel content is not well controlled (very prone to bubble place)
3. Machine is clean (this point will not cause air bubbles, but it is prone to the same thing similar to the ice, especially cyclohexanone)
4, To bracket the viscose, the drum speed is not fast.
5. change Glue, clean the rollers and led lights.
6. viscose machine.

what are led light bulbs and white led

what are led light bulbs? The white LED lights source lighting with green, long life, energy saving, small size, light weight, quick to respond, low operating voltage and good safety characteristics, known as the 21st century green replacement for incandescent, fluorescent and energy-saving lamps. LED white light is a variety of ways, are now widely used and has achieved industrialization is the launch of the white phosphor coating on the LED chip. Because LED uses three methods to achieve white light of fluorescent powder, technically does not fully mature, so severely limited the wider application of white LED lighting in the area.

what are led light bulbs and white led

There are 3 different methods to achieve white led, then you could know what are led light bulbs.

The first scenario is Blu-ray excitation of the yellow phosphor coating a blue LED street light chip, the principle is the blue chip issued by the yellow light and fluorescent powder complementary to the formation of white light. However, the principle disadvantage of this program is the phosphor emission spectra of the Ce3 ion with the characteristics of a continuous spectrum, therefore, poor color, luminous efficiency is not high enough, it is difficult to meet the needs of low color temperature lighting, in order to solve this problem must be improved through the development of new highly efficient phosphor.

The second option is the blue LED chip coated with green and red phosphors, the principle is issued through the chip emits blue light phosphor green and red compound obtained white, so color is more better. The drawback is that this program of phosphor conversion efficiency is low, only to improve the efficiency of red phosphors can be improved.

The third program is the three primary colors or multiple color phosphor coating in the violet or ultraviolet LED high bay chip, the principle is the chip launch the long-wave ultraviolet light (was 370nm-380nm) or violet (380nm-410nm ) to stimulate phosphor to achieve white light emission color of this program to be better than the previous two programs, but the effective conversion efficiency of the phosphor is also low, and red and green phosphors generally sulfide system, so this kind of luminescent stability of the phosphor, the light fades larger. Only to develop more efficient, low-light decay of LED phosphors in order to achieve higher conversion efficiency.

what is a led bulb with different circuit

what is a led bulb? LED in the commercialization of specific applications often need dozens or even hundreds of LED combinations together,  constitute the light emitting device, the LED load circuit connected directly related to the reliability and service life of LED components. This is because the LED circuit can work safely, and its basic function has two aspects: First, to maintain a constant current. Second, the drive circuit should be kept lower power consumption, in order to make the efficiency of the LED high bay system in a high level.

what is a led bulb with different circuit
A wide range of LED in the form of the connection circuit are listed below: series, parallel, series parallel combinations. Then you would know what is a led bulb.

1, Series: The series circuit is the number of the LED cathode to anode connectedclusters, the advantage of operating current through each LED are generally required tostring together with the current limiting resistor. The drawback is that this circuit requires apower supply higher voltage. Voltage equation and the circuit current using the following formula:
V total = LED VF = VF1 + VF2 + VF3 … + VFn
I = total individual LED IF value

2, parallel: parallel circuit is the number of LED cathode and anode, cathode andanode parallel connection, which is characterized by the operating voltage of each LED, total current is ΣIFn, in order to ensure that each LED current IF. needs consistent with the forward voltage of each LED. However, this circuit drawback is that the power supply can provide a higher current. Voltage equation and the circuit current using the following formula:
V total = VF value of each LED
I total = each LED IF =, IF1 + the IF2 + IF3 … + IFn

3, series / parallel combination of: the LED connected in series / parallel combination ofform, the biggest benefit is you can significantly reduce the impact of VF inconsistent. Also, we should be reminded that,   changes in the composition of the array form or LED street light number should also be timely adjustment of the current limiting resistor. Appropriate current limiting resistor in order to effectively control the current in the circuit configuration in the circuit. Of course, the series / parallel combination circuit causes the output current with the input voltage and ambient temperature and other factors, a significant change occurs.

This is the answers of what is a led bulb.
