Blue spectra are the highest frequency spectra of visible electromagnetic waves observed by the human sense. From the point of view of quantum photons, blue is the most energetic of the white illumination of the visible spectra. For these reasons, it is technologically suitable for the production of photons generating the converted type with lower energy after the impact of higher energy photons on the converter-phosphorus mixture or barite of white LEDs.

LED driver description

LED ballast design

Proper filtering is a must, there is a standard. Class D surge protection with varistor - use is inconsistency. This can cast a bad shadow on the conductor by frequently breaking the fuse caused by surges in the electricity. This is mainly the surge protection of the building's electricity as a whole.

The most used types of topologies:

  • Simpler quasi-resonant Flyback with implicit active power factor correction for input power up to 120 W.
  • More complicated resonant LLC for input power over 200 W.

Flyback, reliability or MTBF topology driver:

  • Input electrolytic: BULK capacitors, active PFC topology eliminates them - higher reliability.
  • The damping capacitor: is of the foil type, not the ceramic type.
  • The secondary rectifier: is an ideal SiC diode using a schotky diode than the excessive dimension twice takes into account the assignment voltage the sum of the output voltage + the reflected primary voltage is divided by the input voltage by the ratio of transformation and rotation.
  • Secondary electrolytic capacitors: polymer type 4 or 6 in parallel or tantalum types. Two pieces applied - lower current ripple at 105°C with ESR.
  • Primary sensing: is suitable e.g. LT3799-1 because the optocoupler is excluded as a potential source of failure. In SMPS, MosFET acts as the sum of four edges - rectified input voltage nominal 325V, Reflected secondary voltage ~ Vout * Ntransformer. Leak induction peak, can be suppressed by Snuber 50 V to 200 V. A fault voltage of 900V MosFET is required.
  • Primary sensing: has a worse effect on the SMPS control loop - good current control ±2 % secondary sensing predicted with very long PI correction below 10 Hz of the current part of the control in constant current mode to suppress LED flicker caused by mains frequency - good result ±5 %. Comparable to primary sensing with good control technology in the control circuit.

Measurement of power consumption. Analysis of mains parameters. Evaluation of economic and statistical indicators.

Questions preceding the decision to invest:

  • Increase technology machine production capacity over currently?
  • Technology reduces operating costs and thus increase the efficiency?
  • We will create some additional benefits?
  • It is an investment in technology final?

Relative spectral emission, neutral white color temperature 4000K

Costs for investment:

  • Initial Cost: purchase, transportation, installation, commissioning.
  • Operation and Maintenance Cost: over the life of technology.
  • Fixed Cost: relatively constant for example levies, taxes, salaries.
  • Variable Cost: dependence on operating activities.
  • Incremental or Marginal Cost: determined from variable costs, eg. increase in performance of some of the technology.
  • Sunk Cost: usually ignored by them.
  • Adjustment Cost: on end of technical life.

Relative spectral emission, cool white color temperature 6000K

Economic variables related to the time:

  • The purchasing power of money finance: themselves typically declines over time. When investing associated with reward, in this case usually grows.
  • Price of technology: typically decreases by time.
  • Price of raw materials: grows by time.
  • The interest rate [%]: Interest - the amount of borrowed funds by banking institution for the use of funds . Depends not only on economic variables over time may rise or fall.
  • Strength of human thoughts: almost infinite value . Little used we act as thought patterns.

Methods for evaluating the profitability and return invesments predictive methods:

  • Payback Period PP: SPP - Single Payback Period, DPP - Discounted Payback Period. Counts with time value of money. Iterative calculation.
  • Return on Investment ROI: DPP - Discounted Payback Period. Involve with time value of money. Iteration method.
  • These two methods are not consistent there aren’t articulated, unsuited with cost over the technical life of technology, do not consider timing cash flow, do not include any costs associated with the specifics of accounting firms: DPP - Discounted Payback Period. Involve with time value of money. Iteration method.
  • Provide a rough approximation investment values. Rough predictive: DPP = year ago + Cost at beginning of year / Cash Flow during a year.
  • However, they are simple, quick, relatively denouncing to measure the profitability of future investments. Lower investment in capital, sufficient for the decision to invest. Weakest method is ROI, since time does not reflect cash flows, that we reduce economic efficiency of the project: ROI = Profit from investments - Investment costs / Invest costs

Other methods of evaluating the profitability of invesments:

  • The total lifetime costs of technology- total LCC - Life-Cycle Cost, present value method.
  • The ratio of savings to investment the method - benefit/cost ratio.
  • Net Present Value - NPV.
  • Internal Rate of Return - IRR.
  • These four methods ae more comprehensive, accurate, used for capital powerful investment.
  • Calculating the value of money present and future.
  • For MAU3 device, suitable methods are SPP for own investments and DPP in the case of credit.

The methods of evaluating the return on invesment SPP:

Brief guide to better invesment. Before you decide to invest in the development. Making GO/NO-GO project decision:

  • Focus on „cash flows: less on profits. Better a sparrow in the hand than a pigeon on the roof proverb. Accounting profits contain a number of economic fictions assumptions, on the other hand, the flow of funds is economic fact manifested reality.
  • Focus on growth „cash flows: carefully imagine alternatives to the project affect change cash flows thus, the desired additions.
  • Calculate over time„Time is money: investors naturally prefer the timing of the flow of finance. Cash rather sooner than later preferably immediately. Just use the NPV method - obtained clean the present value of potential investments.
  • Calculate the investment: risk. way ride out variable risk is the use of variable discount rate in the calculations, there is most consistent with the investment risk . Recommended inverse relationship - the higher the risk the earlier calculated return on investment.
