This progressive optical filter 13 is arranged in the lamp housing 11 rotationally; And be oppositely arranged with illuminating module 12; Progressive optical filter 13 can perpendicular direction be rotated around the direction of propagation of the many primary colours collimated light beam 102 that is sent with illuminating module 12, be used for the light transmission that makes many primary colours collimated light beam 102 subwaves long.The principle of this progressive optical filter 13 is: progressive optical filter 13 fixedly lets the light of certain wavelength pass through; And when progressive optical filter 13 certain angle of rotation (that is: the incident angle of many primary colours collimated light beam 102 incident progressive optical filter 13 changes); Can squint through the spectrum of this progressive optical filter 13; Can pass through through the light of different other certain wavelength of light wavelength before the transference rotation, and when the light of different wave length was passed through, the light color that is displayed was just different.That is: through rotating this progressive optical filter 13, make in many primary colours collimated light beam 102 and can pass through, thereby change the color that many primary colours collimated light beam 102 sends light after through progressive optical filter 13 through the light of this position progressive optical filter 13.
In the present embodiment, progressive optical filter 13 is arranged in the lamp housing 11 through tumbler 15 rotationally.Particularly, this tumbler 15 is arranged in the lamp housing 11, and between illuminating module 12 and light-emitting window 111, the direction of propagation of many primary colours collimated light beam 102 that the axis of tumbler 15 and illuminating module 12 are sent is perpendicular.Offer through hole between the first surface 133 of this progressive optical filter 13 and the second surface 134.The axial direction of this through hole is parallel with second surface 134 with first surface 133; Be used for this tumbler 15 affixed; Under the drive of tumbler 15, can the rotate axis of moving part 15 of progressive optical filter 13 is rotated; Incident angle
to change many primary colours collimated light beam 102 incident progressive optical filter 13 that illuminating module 12 sends is certain; Progressive optical filter 13 also otherwise is arranged in the lamp housing 11 rotationally, as long as make the progressive optical filter 13 can be around rotating with the perpendicular direction in the direction of propagation of many primary colours collimated light beam 102.
As shown in Figure 3, for clearly demonstrating the operation principle of this colored lamp 10, line AA ' position is defined as 0 degree position, promptly progressive optical filter 13 rotational angles are confirmed as basis of reference with this line AA '.This line AA ' is perpendicular with the direction of propagation of many primary colours collimated light beam 102 that illuminating module 12 is sent.
Obtain the color of light as required; Incident angle
when determining many primary colours collimated light beam 102 incident progressive optical filter 13 that illuminating module 12 sends according to this incident angle
obtain progressive optical filter 13 from be parallel to line AA ' position rotate moving part 15 required rotations angle
then; Rotate moving part 15 of progressive optical filter 13 is rotated this angle θ; Open illuminating module 12 simultaneously, make the white light LEDs of illuminator 122 send the white light that is parallel to each other.This white light of the incident angle of this white light incident progressive optical filter 13
is in the thin layer 132 of progressive optical filter 13; Have the refraction and the reflex of different refractivity and different-thickness film through multilayer; Light wavelength through progressive optical filter 13 is squinted; So that allow light transmission progressive optical filter 13 ejaculations, thereby make colored lamp 10 send the light of required color through the wavelength corresponding color of progressive optical filter 13 with the skew back.
When the progressive optical filter 13 of colored lamp 10 was provided with the thin layer of enumerating in the table 1 132, when progressive optical filter 13 different rotation angle θ, colored lamp 10 sends light wavelength and color is specially:
Progressive optical filter 13 is in the position that is parallel to line AA '; It is progressive optical filter 13 rotational angle θ=0 degree; It is that the light of 460.0nm to 610.0nm can see through progressive optical filter 13 and penetrates that the incident angle
that illuminating module 12 is sent light beam incident progressive optical filter 13 makes the white light LEDs medium wavelength, can obtain purple light.
Progressive optical filter 13 is in the position that becomes 30 degree angles with line AA '; Be progressive optical filter 13 rotational angle θ=30 degree; It is that the light of 445.0nm to 580.0nm can see through progressive optical filter 13 and penetrates that the incident angle
that illuminating module 12 is sent light beam incident progressive optical filter 13 makes the white light LEDs medium wavelength, can obtain pink.
Progressive optical filter 13 is in the position in angle of 45 degrees with line AA '; Be progressive optical filter 13 rotational angle θ=45 degree; It is that the light of 415.0nm to 565.0nm can see through progressive optical filter 13 and penetrates that the incident angle
that illuminating module 12 is sent light beam incident progressive optical filter 13 makes the white light LEDs medium wavelength, can obtain orange-colored light.
In the present embodiment, progressive optical filter 13 is more little from being parallel to the line AA ' angle that moving part 15 rotates that rotates, and it is short more to see through the corresponding wavelength of the light of progressive optical filter 13.
In addition, for realizing adjusting automatically the glow color of colored lamp 10, can progressive optical filter 13 and other control systems be electrically connected, with the rotation of control progressive optical filter 13.
It is understandable that, for the person of ordinary skill of the art, can make other various corresponding changes and distortion by technical conceive according to the present invention, and all these change the protection domain that all should belong to claim of the present invention with distortion.
