Abstract
The utility model provides a projector light device with CMY color conversion system, comprising a light body (3), an arm and a base (1) for supporting the light body, wherein the light body (3) comprises a bulb (4), a light reflecting bowl (5), and a CMY color conversion system (6), the CMY color conversion system (6) comprises two support plates, a pair of dimmers or color chips which can move relatively are arranged on the positive and opposite faces of each support plate, the color chip comprises a pair of blue chips, a pair of yellow chips, and a pair of magenta chips. The utility model overcomes the disadvantages that general projector light has small spot area and low brightness, thereby providing a projector light with simple structure, large spot area and high brightness.
Description
Technical field
The utility model relates to a kind of projecting lamp that is used for place illuminations such as large-scale building, open deck or monument, particularly relates to a kind of projecting lamp with CMY colour switching system.
Background technology
Known this projecting lamp type is that reverberation passes through the conversion of painted or dimming system again, obtains required projection effect after being reflected by the reflector of light through being positioned at the light source back that light source sends.Light source wherein adopts bulb single-ended or that both-end is fixing, but no matter be to adopt single-ended or both-end form, for the fixing consideration of bulb, the reflector tail end must be provided with an opening or fluting, and that part of light that shines this opening or fluting that light source sends then loses because of not reflecting, also have, because the reflector bore that such projecting lamp uses is less, light emitted still has considerable part to be reflected to the light in side the place ahead, has also caused the loss of light.For above-mentioned reasons, the brightness of this projecting lamp is darker.In addition, because the bore of reflector is less, corresponding colour switching system also can only adopt undersized scale, so the facula area of projection is also less, under large-scale occasion, needs this projecting lamp of a lot of platforms could satisfy the projection needs usually.
Summary of the invention
The purpose of this utility model is to have the shortcoming that facula area is little, brightness is low in order to overcome existing color conversion projecting lamp in projection, and a kind of simple in structure and projected area is big, brightness is high projector device is provided.
In order to achieve the above object, the technical solution adopted in the utility model is: the utility model is by lamp body (3); The arm (2) and the base (1) that support lamp body constitute; Described lamp body (3) comprises bulb (4), reflector (5), CMY colour switching system (6), and described base (1) comprises power supply (7), light source control unit (8), CMY control module (9).
Described CMY control module (9) comprises the drive circuit of signal input output interface, microprocessor chip, stepper motor, to carry out exercises, finishes the function of projecting lamp.
The utility model adopts bigbore reflector, and reflector is divided into two-section, wherein bowl bottom is divided into activity form, can after installing bulb, lump together fastening with forward part again, so an opening or a fluting needn't be set at the tail end of reflector, guaranteed that the light that light source is launched can both be reflected backwards, overcome illumination in the known technology and be mapped to and reflect behind the opening of reflector tail end or the fluting and cause the shortcoming of light loss.Simultaneously, owing to adopt the heavy caliber reflector, so reflective area is big, it is less to scatter to the unavailable light in side the place ahead, and light has obtained utilizing largely, has improved brightness, the big light hole that cooperates CMY colour switching of the present utility model system to use just can obtain bigger projected spot.
Described CMY colour switching system (6) comprises two support plates, and the positive and negative of every support plate is equipped with a pair of dimmer or color chips that can relative motion, and color chips comprises a pair of blue color chips, a pair of yellow color chips, a pair of magenta color chips.Two dimmers are used to weaken luminous flux, luminous flux can be reduced to always to be interdicted fully; Every pair of color chips can relatively move, and increases the saturation degree of color, thereby reaches CMY colour switching effect.In order to obtain big projected spot, what the utility model adopted is the CMY colour switching system (6) of big light hole, like this, just requiring to have bigger color chips, the also corresponding increase of the weight of color chips, for the stability of system, the utility model has adopted pulley (10) to add the form of guide rail (11) in CMY colour switching system.With the rope traction color chips relative motion of connection pulley, what connect pulley (10) also can be band shape or the flexible article of pencil, then conduct guiding of guide rail (11) and the increase stability that other material is made.
The beneficial effects of the utility model are: simple in structure, the light projected area is big, brightness is high.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a lamp body structure schematic diagram of the present utility model;
Fig. 3 is that base of the present utility model uses reference view;
Fig. 4 is a CMY wink transformation system schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Structure of the present utility model comprises the arm (2) and the base (1) of lamp body (3), support lamp body as shown in Figure 1; Lamp body (3) structure comprises bulb (4), reflector (5), CMY colour switching system (6) as shown in Figure 2; Base (1) comprises power supply (7), light source control unit (8), CMY control module (9) as shown in Figure 3.
During use, connect power supply (7) earlier, the ballast of light source control unit (8), trigger, electric capacity teamwork, light bulb (4), reflector (5) becomes a branch of circular light beam with the light reflection pinching that bulb (4) sends, circular light beam passes through the CMY colour switching system (6) in reflector (4) the place ahead again, the schematic diagram of CMY colour switching system (6) as shown in Figure 4, comprise two support plates, the positive and negative of every support plate is equipped with a pair of dimmer or color chips that can relative motion, and color chips comprises a pair of blue color chips, a pair of yellow color chips, a pair of magenta color chips.Near bulb (4) is a pair of dimmer, and two dimmers are used to weaken luminous flux, luminous flux can be reduced to always to be interdicted fully.Each relatively moves to color chips, can increase the saturation degree of color, thereby reaches CMY colour switching effect.Be the heavy caliber reflector (5) that cooperates the utility model to adopt, CMY wink transformation system (6) adopts big light hole, can make the light beam that passes through bigger, and the facula area that irradiation is come out is also just bigger.
