AC-line powered led: The next generation for LED bulbs and luminaires

ac-line powered led - ac led circuit design

Your led transformer will fail to work before led chips ?

Commonly, led lighting fixtures can only work on DC Voltage, while most of our power supply AC110-240V, then you need a transformer to cover AC220v to DC input, and usually transformer only have 26,000 hours lifespan, the transformer will have less lifespan if the led lights fixture have not a good heat sink or design, but actually LED have almost 50000 hours lifespan, this results in short lifespan of led lights and maintaining cost.

but we have good news, The next generation of AC solutions for LED bulbs and luminaires has arrived.  

 

 

The AC-line powered led have the following advantage:

  • driverless, you could directly connect AC 110-240v for this ac-line powered led, do not need a led driver inside.
  • at least 4 years warranty, during past 2 years we have been testing our AC led products day and night(24hours/day), no one fail to work, so it is confident to offer 4 years warranty to our customers
  • lower light decay: after 2 years engineering testing(24hours/day), only get 3~5% light decay
  • dimmable: all of them can be dimmable from 40% to 100%, do not need dimmable driver any more
  • 4000V High voltage shock passed, with a scientific design, it can pass CE standard 4000V testing
  • UL SAA TUV standards compliance

    Hi. Thank you Blog! It didn’t occur to my I could return my bulbs to Costco. My bulbs have had a shretor than expected lifespan, but no one’s mentioned that they could still be worthwhile based on the low price, and the savings in electric costs, and the cost of energy use to the environment. They claim I can save $93 per bulb. Even if they’ve exaggerated the electric cost I pay, and the usage of a traditional bulb, there still could be a substantial savings? Let’s see, I have 18 bulbs in my apartment and if I save $50 each/2 years, that should save $450/year ($820 if $93/bulb). My actual electric use is something like $600+/year, not all lighting. Well, they’ve probably exaggerated the savings, (I don’t know what I would be paying in electric) as they did the lifespan, but it’s probably quite worthwhile compared to traditional incandescent bulbs the savings are 1/10 what they say. I’m not sure about the pollution cost of the bit of mercury. Maybe soon LED’s will solve that problem(?). I recorded on some bulbs dates:23 watt bulbs lasted this many months: 13, 5, 8, 6, 11 (8.6 months average). Honestly in the main area they’re probably on > 3hrs/day, so if it’s 6 hrs/day then they warranty 1 year. Still, they don’t meet their claims, but may still be very worthwhile in electric savings and cost, and possibly environmental damage. Better than traditional incandescent, but it’s possible competing fluorescent would last longer and put less mercury in the environment (?, or, maybe not).

    Hello would you mind sharing which blog platform you’re working with?
    I’m looking to start my own blog soon but I’m having a hard time choosing between BlogEngine/Wordpress/B2evolution and Drupal.
    The reason I ask is because your design and style seems different then most
    blogs and I’m looking for something completely unique.
    P.S My apologies for getting off-topic but I had to ask!

    I’ve been surfing on-line greater than three hours today, but I never found any attention-grabbing article like yours.
    It’s lovely worth sufficient for me. Personally, if all webmasters
    and bloggers made good content as you probably did, the web will probably be a lot more useful than ever before.
