摘要 |
The light generator comprises a housing (1) with a light source in the form of a plurality of LEDs (3, 3', . . . ), each having a luminous flux of at least 5 lm during operation. The housing (1) also comprises a collimating lens (6) and a Fresnel lens (8) for focusing the beam generated by the LEDs (3, 3', . . . ). The light engine is further provided with drive means in a box (10) for driving the LEDs (3, 3', . . . ). Preferably, the collimator lens (6) has a number of sub-lenses (7, 7', . . . ), the optical axis of each of the sub-lenses coinciding with the optical axis of a respective one of the LEDs (3, 3', . . .). |
