Inventia se refera la un sostem de iluminare, fara oglinda, pentru retroproiectoare realizat cu un bec auto al carui filament auxiliar se afla pe axa optica a retroproiectorului deasupra ecranului propriu care are rol de oglinda si se afla în balonul becului. Becul este fixat pe un suport ce se fixeaza prin intermediul unor placute de reglaj pe peretele inferior al carcasei reproductorului. în plan lateral, reglajul secundar se face prin deplasarea suportului în lungul canalelor practicate în suport. Reglajul principal se realizeaza prin deplasarea becului în orificiul de fixare în suport.The invention relates to a lighting system without a mirror for a retro-projector made with a car bulb whose auxiliary filament is on the optical axis of the overhead projector above its own mirror screen and is in the bulb's bulb. The bulb is attached to a holder that is secured by means of adjusting plates on the lower wall of the speaker case. In the lateral plane, the secondary adjustment is made by moving the support along the grooves in the support. The main adjustment is made by moving the bulb in the mounting hole in the bracket.
