Embodiment 1
Light-gathering scan lamp among Fig. 1 and Fig. 2 is made up of light source, gathering directional light generating means, the reflective line scanning device of rotation.Wherein assembling the directional light generating means is distributed according to the order of sequence by 4,3 and little convex lens 5 of two big convex lens and constitutes.Light source 2 is positioned at the focus place in convex lens 3 outsides, and the spherical reflector 1 that the center of circle is positioned at 2 places is housed behind, and the focus of little convex lens 5 oppositely overlaps three all coaxial secured in parallel of convex lens with big convex lens 4.The border that rotates reflective line scanning device 8 is evenly equipped with some groups of reflective surfaces, and every group of reflective surface is made up of the reflective mirror 6 and 7 of relative forming V-shape.Assemble the side that the directional light generating means is positioned at the reflective line scanning device 8 of rotation during assembling, little convex lens 5 wherein are facing to close reflective mirror 6.
When the light-gathering scan lamp of present embodiment is worked, the scattered light that light source 2 sends is reflective through reflector 1, and in assembling the directional light generating means big convex lens 3 and become directional light, again through big convex lens 4, little convex lens 5, be transformed into a branch of direct projection directional light of high brightness, minor diameter.The high brightness direct projection directional light that sends from little convex lens 5 shines on the reflective mirror 6 of the reflective line scanning device of rotation, and reflexing to through another reflective mirror 7 these faces of refraction relative with it needs illumination place again.Rotate reflective line scanning device 8 by driven by motor, when clockwise rotating by required rotating speed, little convex lens 5 are done the counter motions from a1 to a3 relatively, and indirect illumination light will move along b1 to the b3 strip region that width equals little convex lens 5 diameters as a result, forms stripscan light; And then because the direct projection directional light shines on next group mirror surface, indirect illumination light is got back to initial illumination b1 place, begins the scanning of following one-period; So move in circles, just produced the illumination shape zone of a band shape.Because the effect brightness of scattered light through assembling the directional light generating means improves greatly, and continuous reflective scan will be because " look and stay " effect will produce the effect identical with continuing illumination.According to calculating, can obviously save the illumination electric energy.
Embodiment 2
The difference of another embodiment of the present invention and the foregoing description is that the back side of assembling the big convex lens 3 in the directional light generating means is coated with reflecting layer 1 ', and the one side of the big dorsad convex lens 3 of light source 2 is coated with reflecting layer 1 ", and be positioned at focus place after big convex lens 3 reflections.Like this, the luminous energy of light source 2 can as much as possiblely project big convex lens 3, and the directional light after big convex lens 3 reflections is incident upon another big convex lens 4 again, makes device compacter.
Embodiment 3
The characteristics of Fig. 4 and the 3rd embodiment shown in Figure 5 are that line scanning and frame scan are combined, both contained the reflective line scanning device 8 of rotation, also contain structure and similarly rotate reflective frame sweep unit 9 with the reflective line scanning device 8 of rotation, the reflective line scanning device of this rotating shaft that rotates reflective frame sweep unit 9 and rotation 8 is perpendicular, is positioned at the reflection side of the reflective line scanning device 8 of rotation.The rotating ratio that wherein rotates reflective line scanning device 8 rotates reflective frame sweep unit 9 height, and the reflective surface circumferencial direction that rotates reflective frame sweep unit 9 is uniform, and its rotating speed does not promptly overlap according to the illuminated area of final formation not to be had empty the leakage yet and determine.When the light-gathering scan lamp of this embodiment is worked, the action effect that rotates reflective line scanning device 8 is identical with embodiment 1, b1 to the b3 strip region reality of reflected-light scanning that different is just in time drops on the reflective surface of the reflective frame sweep unit 9 of rotation, and the result is reflected once more and drops on b1 ＇ to the b3 ＇.Collocation according to suitable rotating speed and reflective mirror quantity, just in time make and assemble a branch of light that the directional light generating means sends, earlier through rotating the stripscan light that reflective line scanning device 8 becomes a measured length, again through rotate reflective frame sweep unit 9 become length greater than b1-b3 (because b1-b3 has certain angle of reflection, therefore amplification is arranged after reflection), width equals a slice scan light of b1 ＇-b3 ＇, because human eye " look and stay " effect, the luminous point that makes the people not feel scan light moves, and as Continuous irradiation.Because in fact be not the each point continuous illumination simultaneously of irradiation area during light-gathering scan lamp work, therefore can save the energy greatly, the less ligthing paraphernalia of a required horsepower just can reach desirable illuminating effect.
