dc.description.abstract | Dispozitivul este elaborat în baza ledurilor Samsung in corp 5730 de 0.5W cu o eficiență luminoasa de 39 Lm/W la curentul de 65mA şi coeficientul de redare a culorii CRI>80Ra. Sursa de alimentare de 220W este devizat în blocuri separate a cîte 36W±5%, ceea ce sporeşte esențial fiabilitatea sursei elaborate şi confecționate. Dispozitivul poate înlocui proiectoarele metal-halogen cu consumul 1÷1,1 kW. Pot fi utilizate lentile individuale pentru fiecare LED cu unghiul de ieşire a luminii 30º şi 60º. Ca rezultat proiectorul elaborat şi confecționat poate fi utilizat pentru iluminarea stadioanelor sau a spațiilor mari. | en_US |
dc.description.abstract | The device is based on the 5730 body Samsung LED with a power of 0.5W, which has a light efficiency of 39 Lm/W on a 65mA current, and CRI>80Ra. The 220W power consumption is divided into six equal segments of 36W±5%, which greatly enhances the reliability of the power supply. The device can replace a metal-halogen projector with a power consumption of 1÷1,1 kW. Individual lenses are provided for each led with 30º, 60º light output angle, which allows using the designed projector for night lighting of large areas and stadiums. | en_US |
