The cooperation in led street signs

As we all know, CREE is one of the top level LED Lighting source suppliers, the cooperation between Eneltec and CREE in led street signs are widely and deeply.

Early in the development of SiC, GaN, and Si substrates, the impression of some people, the Cree chips and material suppliers. Now, CREE is becoming a better supplier in all LED industry.

About  the cooperation between Eneltec and CREE, we use Creee Xlamp series of lighting sources in LED Down Lights, LED Spotlights, etc. These days, the R&D center of Eneltec is taking a negotiation with CREE, to use the CRee LED in our news series of  led street signs, LED High Bay etc.

Cree products are widely used in national key projects of the Beijing Olympics and Shanghai World Expo. According to incomplete statistics, approximately 12,000,000 pieces of Cree LED is used directly for the Shanghai World Expo. As   the marketing center of Eneltec is located in Shanghai, so we do the inspection for every projects in Shanghai World Expo.

Now, during these 2 years, Eneltec changed the LED series of CRee from Xlamp to Cree XPE, which output 100-140lm/w. With the support of Eneltec heat sink design, the next step could be more than 200lm/w. This is really a big development of LED technology.  Also, after the updated technology, the heat output would be reduced 50%, it’s good for not only the lifespan of LED lamps, but also light loss. After the this new technology application of led street signs, the market share of Eneltec would be increasing rapidly.

led strip lighting kitchen would ask, Edison invest the incandescent lamps?

As we all know, Thomas Edison invest the incandescent lamps？But is it the truth?

Actually, Heinrich Göbel invest the incandescent lamps with the same concept 10 years before Edison, also, many scientists do a lot of contribution to the development of incandescent lamps. Thomas Edison do some development, but not investment. Just like the led strip lighting kitchen.

In 1801, English scientists-David, link the Platinum wire to line voltage and make it light up. In 1810, he invented the electric candle, between two carbon rod arc lighting.

In 1854, Heinrich Göbel used a carbonized bamboo filament placed in the vacuum glass power light. This investment is regarded as the first incandescent lamp, because his incandescent lamp would be working for more than 400 hours. But he didn’t apply for a Patent at that time.

In 1850, Joseph Wilson Swan from UK, started working on incandescent lamps. In 1878, he got the British patent by the power of the carbon filament light bulb under vacuum. Then he founded a company in UK and start installing the incandescent lamps for people.

In 1874, two electricians from Canada applied for a patent for incandescent lamps. They put the glass bulb filled with helium gas to the power of the carbon rod light. But they don’t have enough money for further development,  so they sold the patent to Thomas Edison.

After he got the patent, Edison tried to use better Filament. In 1879, he use ​​carbon filament light bulbs, and the bulbs start lighting for 13 hours. In 1880, the new bulbs would be working for more than 1200 hours.

Now, it’s so obvious that Edison is not the first one who invest incandescent lamps, but why almost everybody think he is the first one? I think the concept is the same as Eneltec. In 2007, I went to a friend’s home, and I was so interested in the led strip lighting kitchen. All the designs and lighting situations are much better than the traditional lightings. Actually, led strip lighting kitchen is only one of the led applications, Eneltec is very famous for their LED High bay, I don’t know who’s the first investor, but I know, Eneltec is the best of best.

Advantage of led studio lighting

led studio lighting is a new generation of lightings. Compared with traditional lightings, they have a lot of advantage.

1. Hide. led studio lighting could be much smaller than the traditional lightings, could be much easier to hide in the buildings.

2. Energy saving. According the test result from top LED high bay company- Eneltec, the power consumpution of led lights could be 10% of  the traditional lightings.

3. Lifespan. The lifespan of traditional lightings would be about 5000 hours, LED lights would be more than 50000 hours, it’s 10 times better than edison lamps and CFL.

4. Safe. As we all know, the traditional lightings are very easy to broke. For the led lamps, as it’s all aluminum struction, during the usage and transportation, the are very safe.

5. Environment. Almost all the traditional lightings are with Hg. It’s a huge harmful thing to our environment. For the LED lights, they are without any Hg, and also easy for assembling and disassembling.

6. Quick start. Whenever you start the traditional lightings, it’s from 2 seconds to 10 minutes to be working normally(HID Lamps), but for led studio lighting, it’s almost no time period to working standardly.

7. Development. As more and more companies focus on the led lights, so the development of led lamps are very quick. It also brings new design, better quality, cheaper prices to these new lighting generations.

8. Service. As LED is a new concept, all the sales of LED lighting companies would be better than the other lighting companies. Better service brings us better knowledge for the led lightings.

certificate for led task lighting

With the development of led task lighting, more an more LED high bay are exported throughout the world from China, so, more and more countries are looking for certificates of the led products.

Now, let’s check what are the most important certificate for led products.

1. In China. CCC means “China Compulsory Certification”, any electronic products which are sold in China must pass the EMC testing and Electromagnetic radiation testing.

2. In North America. UL is well knows as UnderwriterLaboratories Inc. This certificate is about the Safety tests and inspections on a variety of devices, systems and materials. Now, UL is the most stick certificate in the world.

3. In Europe. CE is a logo for safety. In Europe, if the products have CE logo, it’s not necessary to do any test of the different European standards. So, CE logo is just like a passport of led task lighting.

4. In the other countries. CB certificate is issued by IECEE (Worldwide System for Conformity Testing and Certification of Electrical Equipment), there are 44 countries accept the CB certificates, which are Argentina, Australia, Austria, Belarus, Belgium, Brazil, Canada, China, Czech Republic,Denmark, Finland, France, Germany, Greece, Hungary, India, Indonesia, Ireland, Israel, Japan, Italy, Kenya, Korea, Malaysia, Mexico,Netherlands, New Zealand, Norway, Poland,Portugal, Romania, Russia, Serbia-Montenegro, Singapore, Slovakia, Slovenia, South Africa, Spain, Sweden, Switzerland, Thailand, Turkey, Ukraine, United Kingdom, United States.

Besides all these certificates, also, we have CQC (China), CSA (Canada), TUV (Germany), FCC (USA), all these certificates are very important for the local markets. If your led task lighting are tested through these standards, it’s much easier to be sold in the world.

how to choose led uplighters to buy?

As we see, there a thousands of LED Suppliers in the world, then how could we choose choose led uplighters to buy?

Normally, during choosing led uplighters to buy, let’s do some analyze of the difference between led products from different suppliers.

1. Heat Sink. As we all know, the heat sink is related to the lifespan of LED. Using the good heat sink system is very important for the quality of the LED lighting products. As we ever tested, the top led high bay supplier Eneltec, they are using 25% bigger Al-motherboard. Then the heat sink of Eneltec lighting products would be much better than the others.

2. Light Distribution. As we all know, there are too many led companies, then how could we analyze the quality? Only solution is buying sampels and then do the testing later? NO! Light distribution is a important method for quality testing. Serious led suppliers would offer Light distribution files in IES format, for testing and designs. Then we could analyze and do the lighting designs by ourself.

Also, if you don’t know how to choose led uplighters to buy, you could ask for IES files firstly. Eneltec have 10 series of led lighting products, as far as I know, most of them are tested and exported to IES files. Also, if you are not a professioanl Lighting designer, you could send the details of the project to Eneltec, the lighting designers of Eneltec would do the designs for you and send you the report within 24 hours. All of these services are free of charge.

Why led task lighting are not universal in China?

A lot of people asked me, Why led task lighting are not universal in China? The reasons are very complicated.

1. Price. As we all know, the cost of LED products are very high,  it makes the price of LED Products are also much higher than the consumers could accept. Normally, Chinese only focus on the prices, never think of the energy saving. Now, if you use led products from good suppliers, like Eneltec (as we all know the top LED High Bayfactory), you could use 7W led to replace 40W Incandescent bulbs, also, you could use 5W led to replace 26W CFL. The future market of led task lighting should not be only in big cities, but also the towns, villages. If we want millions of people buy the led products, firstly, you should make billions of people who know about the led products.

2. Environmental protection. The western countries buy a lot of LED products, why? Just because they are rich? NO. The most important reason is that, they have the concept of Environmental protection in their mind. If everybody in China really understand the importance of Environmental protection, the led products could be sold well in China.

3. Technology. Based on the technology now, led could output about 100lm/w. It’s still not high enough to replace all the traditional lightings.

If the led task lighting could output 200-250lu/w, the total cost of led products would be 50% off, at that time, the led would be universal in everywhere, even in China.

Worry about the Radiation of CFL? Use led vehicle lighting!

Nowadays, some newspaper says, the Radiation of CFL (Compact Fluorescent Lamp) is very high, also, it could be harmful to people’s health. Is that true?

Actually, the CFL means the Fluorescent with self-ballast inside. These designs started in the beginning of 70′s. The advantage of CFL is that, the power consumption is much lower compared with Incandescent lamps, and also longer lifespan.But as the competition is more and more tough between the CFL suppliers. A lot of CFL manufacturer produce CFL which could not pass the IEC testing.

Eneltec (as we all know the top led high bay producer) test 87 samples from different CFL suppliers, according to the standard of IEC 62493:2009,  and found, from all these sampels, Radiation is much lower than the Mobile phones, for example, Iphone 4s.

Based on these results, if we don’t want to CFL, we should also don’t use Iphone. It seems not so possible, even the Nokia N10 is much better than Iphone 4s.

The situation is also happened in vehicle lighting. The power consumption of HID lamps are very high, compared with led vehicle lighting.  I have a good friend who works for Volkswagen, who told me more than 30% percent of vehicle lighting are turning to useled vehicle lighting. Also, Eneltec tested the Radiation of HID Lamps and led vehicle lighting, and found, the led products could be 80% better in the performance of Radiation testing.

Now, if we want to be safe from the Radiation, let’s use LED Products, CFL is the past, LED is the future!
