Abstract
The utility model has been announced a kind of stage lighting/projection lamp secondary reflecting device, comprises light source and the reflector that is arranged on light source outside, it is characterized in that: described reflector open front is provided with has the extension reflection shield that oral area reduces.Described reflector negative camber is oval calotte, and the negative camber of described extension reflection shield is on the extension track of reflector oval calotte, and described light source is arranged on the focal position of described reflector negative camber.The utility model again reflects the part light of the scattering at reflector opening part to converge by extending reflection shield, increases the reflectivity to light source in same power light source situation, and then improves brightness.Under the prerequisite of same brightness, can reduce light source power, and then reach energy-conservation object.Can also make defeated light-emitting type more reach perfect condition.
Description
Technical field
The utility model relates to a kind of lighting device, particularly relates to a kind of stage lighting/projection lamp secondary reflecting device that improves light extraction efficiency.
Background technology
Existing stage bulb/projection lamp is all to carry out reflecting light by being arranged on the light that the bulb at reflector center sends as shown in Figure 1, because reflector shape curved inner surface is open form formula gradually, the part light that bulb sends scatters out along the opening part of reflector, has reduced the light emission rate of light fixture.Light fixture shown in Fig. 1 only has 55.2% left and right to light reflector service efficiency, and illumination output is subject to anterior direct projection light impact, has had influence on defeated light-emitting type.
Summary of the invention
The utility model object is to provide a kind of raising light source utilization rate according to the defect of prior art, improves stage lighting/projection lamp secondary reflecting device of reflection illumination.
The utility model for achieving the above object, adopts following technical scheme:
Stage lighting/projection lamp secondary reflecting device, comprises light source and the reflector that is arranged on light source outside, it is characterized in that: described reflector open front is provided with has the extension reflection shield that oral area reduces.
It is further characterized in that: described reflector negative camber is oval calotte, and the negative camber of described extension reflection shield is on the extension track of reflector oval calotte, and described light source is arranged on the focal position of described reflector negative camber.
Preferred: the angle between described light source and reflector opening is 93 degree, described light source is 35 degree with the outlet angle that extends reflection shield.
The utility model again reflects the part light of the scattering at reflector opening part to converge by extending reflection shield, has following advantage:
1. with the reflectivity increasing in power light source situation light source, and then improve brightness.
2. with reducing light source power under the prerequisite of brightness, and then reach energy-conservation object.
3. make defeated light-emitting type more reach perfect condition.
Accompanying drawing explanation
Fig. 1 is this prior art structural representation.
Fig. 2 is the utility model structural representation.
The specific embodiment
Stage lighting/projection lamp secondary reflecting device as shown in Figure 2, comprise light source 1, be arranged on light source 1 outside reflector 2 and with the reflector 2 openings extension reflection shield 3 that oral area reduces that joins.Described reflector 2 negative cambers are oval calotte, and the negative camber of described extension reflection shield 3 is on the extension track of reflector 2 oval calottes, and described light source 1 is arranged on the focal position of described reflector 2 negative cambers.Angle between described light source 1 and reflector 2 openings is 93 degree, and described light source 1 is 35 degree with the outlet angle that extends reflection shield 3.
Figure 1 shows that light source carries reflector, wherein F1 point is light source 1 position, and whole reflector 2 negative cambers are oval, so the light that reflector 2 can produce light source 1 is all concentrated, reflex to F2 point; But as shown in Figure 1, the anterior light of reflector 2 all will be dispersed and cannot assemble, and affect whole defeated light-emitting type, light source effective reflecting surface is (360-68-93)/360=0.552.
Figure 2 shows that the rear schematic diagram of the front increase extension reflection shield 3 of reflector 2, wherein extend reflection shield 3 curved surfaces identical with reflector 2 curved surfaces, it is the prolongation of reflector 2 ellipses, after adding extension reflection shield 3, can make light source 1 utilization rate reach (360-68-35)/360=0.714, with power with in light source situation, add that to extend the exposure intensity that F2 point bears after reflection shield be the 0.714/0.552*100%=129.3% that does not add reflection shield.
Reflection shield is fixed on to corresponding bulb installation site in light fixture, so more changes the bulb on reflection shield and the no impact of whole light fixture; Increase after reflection shield, with power, with in light source situation, brightness output is not add 129.3% of reflection shield, improves on year-on-year basis 29.3%, or under equal brightness requirement, on year-on-year basis energy-conservation 30% left and right; Increase after reflection shield, on an equal basis greatly improved final defeated light-emitting type.
Claims (3)
1. stage lighting/projection lamp secondary reflecting device, comprises light source and the reflector that is arranged on light source outside, it is characterized in that: described reflector open front is provided with has the extension reflection shield that oral area reduces.
2. stage lighting/projection lamp secondary reflecting device according to claim 1, it is characterized in that: described reflector negative camber is oval calotte, the negative camber of described extension reflection shield is on the extension track of reflector oval calotte, and described light source is arranged on the focal position of described reflector negative camber.
3. stage lighting/projection lamp secondary reflecting device according to claim 1 and 2, is characterized in that: the angle between described light source and reflector opening is 93 degree, and described light source is 35 degree with the outlet angle that extends reflection shield.
