The current invention has a light blocking wall to prevent people from directly seeing the laser light source and sensor means to detect when people are near the laser project light and automatically turn off the laser projection light. Hence, the invention totally solves the problem of harm to people's eyes caused by direct viewing of the laser light source.
- (2) The current invention also relates to a laser projection light which incorporates a laser, hologram, and/or grating optics means to cause the laser light beams to make desired geometric patterns that can be seen on desired surfaces including walls and a ceiling.
- (3) The current invention further relates to a laser projection light which incorporates more than one laser, hologram, and/or grating optics means to change a related position of the said laser, hologram, or grating optics means by adjustable means, motor means, or other moving means to provide a variety or plurality of continuously changing light effects, including steady, random, chasing, fade in and fade out, and any other known lighting effects.
- (4) The current invention further incorporates LED light means to cause the laser projection light to have a night light function and offer illumination for an area near the laser projection light. Sometimes, people do not like laser projection on walls or ceiling or ground, so they can turn off the laser projection light and only keep the LED night light as a normal LED night light function. Because the laser and LED power source can use very similar electric signals, the LED and laser can be arranged in one unit without any special technical difficulties.
- The current invention thereby provides the following advantages (1) it protects people's eyes from direct exposure to the laser light beam, (2) creates a variety, of changeable laser light performances by incorporating more than one laser, hologram, or grating optics means and/or motor means, adjustable means, or moving means to change positions of the optics means and create eye-catching effects, and (3) incorporates an LED light source to provide one unit with two different light sources to become a very practical night light and projection light.
