"The new Sundaya series "Sundaya Ulitium" encompasses LED lamps, LCD televisions and suitable solar modules as well as a distribution box for installation using plug and play. The modular construction creates the highest possible flexibility.
The system is suited for garden houses and garages as well as for camper vans and solar home systems. Users can expand the number of lamps and televisions in practically unlimited quantities and can combine them with each other. Depending on the number of devises and luminous period desired, Phaesun offers four different module sizes with outputs between three and twelve watts. The LED lamps consume extremely low amounts of energy and are very effective. For 240 lumens of light output over six hours, eight kilojoules of energy per hour are sufficient, which a solar module can supply with an output of only three watts.
If one dims the lamps, which is possible in three steps, they need even less energy - at 120 lumens, they can be illuminated, for example, for 12 hours. The Sundaya lamp also leads the field as far as efficiency is concerned. While a conventional light bulb delivers one percent and a low-energy light bulb five to ten percent, the new LED lamp from Sundaya has an efficiency of 23 percent.
The electronics and a lithium-ion rechargeable battery have been integrated in the lamps and television. By using a distributor box, one can connect the solar modules directly to the users system. A charge regulator is not necessary. At a candle power of 240 lumens, the rechargeable battery will last three to four years, at 120 lumens six to eight years."litium 200
The Ulitium is Sundaya’s next generation of DC lighting products. Using the energy-efficient LED technology, it allows for an affordable system, which is also modular and expandable according to the consumer's needs. Starting typically with one system consisting of a small solar panel connected to a Ulitium lamp, the system can be expanded by adding more panels and lamps as required. The configuration can be as large as the user desires, spanning across the entire home. A Lithium battery pack is housed inside each Ulitium lamp, thus eliminating the need for a centralized controller and tedious maintenance. Because the energy consumption of the Ulitium is very low, it does not require large solar panels, making the Sundaya Ulitium range the best choice for solar DC lighting in the years to come.
- 240 Lumen light output (equal to 7W CFL bulb or 40W incandescent bulb).
- 23% efficiency (compared to 1% for incandescent and 5% for CFL).
- Built-in Energy Storage (60kJ) and management electronics (no need for separate battery and controller anymore). Solar panel plugs in directly to the lamp through a Hub (which provides lightning surge protections).
- Dimmable from 240 Lumen, down to 120 Lumen, 25 Lumen, and off position, by integrated pull-switch.
- Extremely low energy consumption:
a. 8kJ/h @ 240Lm
b. 4kJ/h @ 120Lm
c. 1kJ/h @ 25Lm
- Long battery life:
a. 7,500h @ 8kJ/h (240Lm), equal to 3.4 years @ 6h/day
b. 15,000h @ 4kJ/h (120Lm), equal to 6.8 years @ 6h/day
- Extremely long life of light-chips:
a. 20,000h @ 240Lm, equal to 9 years @ 6h/day
b. 40,000h @ 240Lm, equal to 18 years @ 6h/day
- Can be charged with very small solar panel of 50kJ/day (3Wp):
a. 240Lm > 50kJ / 8kJ/h = 6h of light per day
b. 120Lm > 50kJ / 4kJ/h = 12h of light per day
- System expandable from 1 lamp to 10 or 100 lamps, simply by adding and connecting more panels and lamps.
- System can be added by a Sundaya LCD Color TV with same built-in Energy Storage technology.
- Automatic regulation of energy between devices that are connected to same PV panel (or array of panels). Devices that are used most will get the most recharging energy the next day.
- Can charge from any 18-24VDC source or any 32-36 cell PV solar panel with maximum Open Circuit Voltage of 25VDC (max).
