Markets that will benefit from the LED Knock-OUT Conversion KITS
Often single input power supply will be satisfactory. Yet this is not compatible with circuits that have a ballast or starter included. To make the single power supply lamps work the starter and the ballast must be removed and the circuit rewired to support it. This seems a hassle to many businesses that want to solve their lighting issues quickly and smoothly. Accordingly many manufacturers of LED tube-lights still supply ballast compatible, bi-input tube lights.
So how do these tube-lights differ and what are their strengths and weaknesses? Is removing the ballast and rewiring worth it? To start with the single input power supply has a major advantage in that it has a lower per unit cost compared to biinput power supply lamps. Also while removing the ballast and rewiring seems inconvenient, it saves time and money in the long run as they also need replacing. Ballasts have a average lifespan of two years, so often, especially with LED lights, it is the ballast that needs replacing more often than the actual lamp. This wastes time and money in the long term. Furthermore single power supply lamps are the safest option. After the ballast is removed and the circuit rewired as they are simply a lot more stable, saving many businesses from unneeded electrical and fire damage in the future. The noticeable downside for single power supply lamps is that it may seem like a unneeded starting cost to remove all the ballasts as in some countries it legally requires a electrician to do this kind of job. This may seem unattractive to business which is reliant on good cash-flow. Finally some countries may also have laws requiring a ballast and obviously this block the entire use of single end power supply.
Bi-input power supply on the other hand, is good if the desire is to Plug and Play after replacing the fluorescent lighting. Rather than, replacing ballasts and the lighting all in an instant which would take more time and money in the shortterm. Though there are three key disadvantages that are present with all bi-input power supply lamps. Firstly they have higher per unit cost when compared to the single power supply. Secondly they have lower power efficiency as the ballast uses power as well; unnecessarily sacrificing energy costs. Thirdly they are not completely compatible with every single type of ballast, especially magnetic. You must ensure you have compatible ballast lights, before purchasing and installing, otherwise time will be wasted. Some variants of bi-input power supply LED lamps can still operate after removing the ballast. This may seem very tempting to companies that want a quick easy fix and no future costs as they would not need to purchase further lighting. Yet future costs is likely what they would come across due to the fact this is extremely dangerous and could easily cause fire. It now seems very clear from the facts presented here, why some of the top LED distributors, have begun recommending their clients to remove the ballast and rewire the circuit to support a single end power supply. This is the smart choice for the long term in terms of time, budget and safety. Distributors and lighting contractors will be making a wise step to switching to only single end power supply LED lighting as long as the countries law does not prevent them from doing that.
Here is this New Invention.
The LED Knock-Out Conversion KITS will eliminate all problem encountered mentioned above. The KITS come all pre-wired with all components needed to convert your existing fixtures making it simple, fast to install and very affordable. The end result is an ALL NEW FIXTURE without removing it; as you convert, you would remove all the fixture components and GiveNewLife to your Troffers and Strip Lights, (which is easy to do) and install the Knock-Out LED Conversion KIT with single end power. TheBONUS is the ability to centre the tubes in your fixture with the sliding feature, adjusting to the required lighting as well as the number of LED tubes needed in any area that need more or less lights.
The advantages of the new FL7794 include:
• Comprehensive dimming capabilities – The FL77944 has all the important dimming capabilities required for smart lighting products, including phase-cut dimming as well as analog and PWM dimming, which is also key for wirelessly connected lighting.
• Scaling for higher power applications – The FL77944’s ability to scale to support higher power applications up to 120W by wiring products in parallel is a critical feature. This reduces the number of different ICs that manufacturers need to keep in inventory.
• Elimination of electrolytic caps – The FL77944 can eliminate the need for electrolytic caps, transformers and inductance coils. This reduces both the bill-of-materials (BOM) costs and the overall complexity compared to designs using SMPS.
• Reduced board space – The FL77944 enables designers to reduce their board space requirements by locating the controller IC on the same PCBs as the LEDs and by eliminating the need for electrolytic caps, transformers and inductance coils.
• Improved reliability and longevity – Products based on the FL77944 should be more reliable and last longer than SMPS-based products as there are inherently fewer points of failure. In particular, eliminating the need for electrolytic capacitors should improve reliability as they are a common source of failures in SMPS-based products.
The new FL77944 is available today and the FEBFL77944 evaluation board can also be ordered. Read the LED Direct AC Drive blog, view the lighting solutions guide and visit the website for more detailed product information about Fairchild's lighting solutions.
The recent advances in the domain of Solid State Lighting (SSL) and, in particular, in Light Emitting Diode (LED) technology has triggered the development of smart lighting solutions. However, the point-like nature of the LEDs imposes the use of either inefficient and/ or bulky light scattering sheets or costly short-pitch LED arrays to achieve acceptable spatial luminance uniformity in, for example, large-area luminaires for professional lighting. Here, we present an innovative thin form-factor light management (LM) system comprising a highly engineered combination of thin-film diffractive nano and refractive micro-optical elements. Our LM solution allows the decreasing of the LED pitch by a factor of 2-3, hence reducing the amount of LEDs for a given total emitting area and luminous flux. The accurate prediction of the system optical response is achieved using interfaced rigorous and ray-tracing modelling tools. Such interfacing is fundamental to account for the complex optical interplay of the different components in the system and, therefore, to ensure meaningful simulation results. The optimized system demonstrates excellent efficiency and luminance spatial uniformity even when combined with long-pitch LED arrays. The LM system presented here has been developed in the framework of the EU-funded project, LASSIE-FP7, whose objective is the realization of a cost-efficient, large-area, efficient, intelligent luminaire with outstanding light quality.
Lighting represents almost 20% of global electricity consumption , similar to the amount of electricity generated by nuclear power and equivalent to 70% of the emissions from the world’s light passenger vehicles. The development and implementation of more efficient lighting systems will undoubtedly make a significant contribution to controlling global CO2 emissions. In addition, LEDs do not contain mercury, in contrast to high efficiency fluorescent lamps. The high efficacy values, close to 60% for commercially available high-power blue and well over 120 lm/W for commercial cool white LEDs, achieved in the last years together with standard lifetime values in excess of 50,000 hours under continuous operation makes LEDs the most convenient light source for energy savings. In fact, LED technology is expected to conquer the lighting market in the coming years with a penetration rate of 56% by 2016 . Large-area light sources represent the most convenient option when a large amount of light is needed and are, therefore, widely used in a variety of lighting segments including office, shop-retail, hospitality, industrial and architectural lighting
segments,which are predicted to be worth 40 billion Euros in 2020.
