dc.description.abstract | Invenţia are drept obiectiv iluminatul stradal eficient, cu calităţi sporite de performanţă. Domeniile de aplicaţie sunt: iluminatul stradal nocturn; iluminatul suprafeţelor mari precum parcuri, parcări. Dispozitivul este construit în baza LED-urilor de ultimă generaţie a companiei SAMSUNG în corp 3030 de 0.5W. A fost utilizată o lentilă monolită, pentru 150 LEDuri. Materialul utilizat este policarbonat cu pierderi proprii pe absorbţie de 11,5%. Sursa de alimentare este construit pe principiul SPEP DOWN, cu un randament de 90%. Dispozitivul este protejat de supraîncălzirea radiatorului de un element de protecţie: releu de temperatură, care deconectează alimentarea atunci cînd temperatura radiatorului depăşeşte 70 °C. | en_US |
dc.description.abstract | The invention has the objective - efficient street lighting, with enhanced performance qualities. Application areas are: night street lighting; lighting of large areas such as parks, car parks. The device is built on SAMSUNG's latest generation LEDs in 0.5W, 3030 chips. A monolithic lens for 150 LEDs was used. The material used is polycarbonate with its own loss on absorption of 11.5%. The power supply is built on the STEP DOWN principle, with a 90% efficiency. The device is protected from overheating the radiator by a protective element: a temperature relay that disconnects the power supply when the radiator temperature exceeds 70 °C. | en_US |
