Have a look the claims of this patent. Let's us know if you agree that they are relevant to circuit arrangements for filaments in LED retrofit lamps. The patent is active in Germany, the UK, France, Italy, Austria and Switzerland. It has counterparts in China and Korea.
LED modules often have capacitors to reduce flicker. The LED, the capacitor and other electronic components are generally arranged on a printed circuit board. This patent allows for smaller form factors by separating LED and capacitor into two seperate structural units. This comes in handy when the form factor of an LED module or fixture needs to be small, such as in poorly accessible areas or where the light source is intended to be as movable as possible.
Solid State Lighting (SSL) modules, such as those for street lighting, need to simultaneously meet various requirements, namely: resistance to electrical overstress (EOS), resistance to thermal dissipation, long service life and mechanical strength. This patent proposes a solution to overcome the problem that these four aspects tend to create opposing constraints.
With this patent, an energy efficient operation of LEDs is made possible by a circuit arrangement, in which two different LED chains can be coupled to a supply source at respectively different points in time.
An aspect of this invention is to save weight for low frequency shields, especially when it comes to large "Zero gauss chambers”, where the lid could be only made from expensive 5 mm NiFe material. With this shape, manufacturers can use much thinner, lighter and cheaper gauges and achieve the same or an even better shielding factor. Almost any kind of magnetic shield which needs a bottom and/or a lid could use this technology. As shields are used in e.g., satellite navigation systems, the smaller weight may have quite a big influence where weight is critical.
By 2050, the global population will reach about 9.6 billion. Food production has to double to feed everyone. Precision agriculture aims to apply the precise and correct amount of inputs like water, fertilizer, etc. at the correct time for yield maximization.
Concerns over pollution require the adoption of energy conservation as well as sustainable generation such as reducing the use of fossil fuels, wide spread use of public transport, more renewable energy production and reducing peak demands with time of use pricing.
The objective of predictive maintenance is to reduce unexpected downtime and increase productivity. To realize this alone would generate around up to 30% over the total maintenance costs. Cyber-physical systems will eventually interfere with physical assets to optimize processes.
Sensors are used in everyday objects and numerous applications of which most people are never aware. Applications include manufacturing, airplanes, cars, medicine, etc.
With the integration of connected sensing systems into energy consuming devices it will become possible to effectively balance power generation and energy usage.
Carbon capture and utilization could help reduce greenhouse gas emissions from coal plants. For example, algal synthesis utilises CO2 as a useful feedstock to grow oil-rich algal biomass for the production of plastics, transport fuel and nutritious animal feed.
Autonomous cars use radar, laser light, GPS, etc. to detect their surroundings. They may also obtain information relating to traffic jams and accidents from other vehicles. Such systems could help avoid most of today’s traffic accidents.
GoodIP is the recommendation platform for patents. We believe that we can find awesome patents when we build a community that knows and talks about inventions in an open source format. By enlisting the vast experiences of all of you we open the discussion of value and potential to the masses.
The owner lists a patent, then the crowd is allowed to review it. It is through the recommendations that we can experience the many different perspectives of a patent, and in the process connect the owner with potential buyers or licensees.
