For this reason, maintenance of the lens and the concave reflecting mirror can be frequently performed. Therefore, the spotlight of the present invention can be used particularly advantageously in a stage or a studio where a stable and high light quantity is required over a long period of time.

The spotlight of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a front view showing a configuration example of the spotlight of the present invention, FIG. 2 is a right side view of the spotlight 10 of FIG. 1, and FIG. It is sectional drawing of the spotlight 10 cut | disconnected along the III line. FIG. 4 is an enlarged view of the light bulb 16, the concave reflecting mirror 15, the socket 17, and the movable support 18 shown in FIG. FIG. 5 is a partially cutaway perspective view showing a configuration of a portion in the vicinity of the light shielding plate 42a shown in FIG.

The spotlight 10 is accommodated on the front side of the cylindrical body 11, a cylindrical body 11 that opens forward and backward, a lid body 13 that can be opened and closed with the rear portion of the cylindrical body 11 as a fulcrum 12 at the rear end of the cylindrical body 11. A lens 14, a concave reflecting mirror 15 having a hole 15a at the center, a tube 16a disposed between the lens 14 and the concave reflecting mirror 15, and a tube disposed between the lens 14 and the lid 13; The light bulb 16 includes a base 16b that is connected to 16a and protrudes rearward from the hole 15a of the concave reflecting mirror 15, and a socket 17 that supports the light bulb 16 with the base 16b inserted. In the spotlight 10, the concave reflecting mirror 15 and the socket 17 are supported and fixed to a movable support 18 provided on the cylindrical side wall surface of the lid 13 so as to be movable in the front-rear direction of the cylindrical body 11. Has major features.

The light bulb 16 includes a tube 16a and a base 16b. The tube 16a is usually made of glass. As the base 16b, for example, a bipost type base is used. The bipost type base 16 b is provided with a pair of rod-like external electrode terminals (not shown) inserted into the socket 17. Instead of the bi-post type base 16b, a known base such as a screw-type base can be used.

Inside the tube 16a, there are a pair of rod-like support electrodes 21a, 21b electrically connected to the external electrode terminal of the base 16b, and a filament 16c installed at the tip of the rod-like support electrodes 21a, 21b. It is arranged.

As the filament 16c, for example, a coil formed of a tungsten filament and further spirally wound (generally called a double coil) is used.

In order to suppress blackening of the tube 16a and the filament 16c, it is preferable to enclose a gas of halogen or a halogen compound (eg, CH ₃ Br, CH ₂ Cl ₂ ) inside the tube 16a. A light bulb in which a halogen or halogen compound gas is enclosed is called a halogen light bulb. In addition to the halogen or halogen compound gas, nitrogen gas, oxygen gas, argon gas, or the like may be sealed inside the tube 16a.

As the socket 17, a known socket corresponding to the cap 16b of the light bulb 16 is used. The socket 17 is preferably provided with a lock mechanism for temporarily fixing the light bulb 16 in a state where the cap 16b is inserted.

The light bulb 16 applies electrical energy generated by a power source (not shown) to the filament 16c through the power cable 22, the electrical wiring 23, the socket 17, the base 16b, and the rod-like support electrodes 21a and 21b. Emits light. In order to suppress the temperature rise inside the cylinder 11 due to the heat generated by the light bulb 16, the cylinder 11 is provided with

ventilators

39a and 39b.

The light generated by the light bulb 16 reaches the lens 14 directly or indirectly through reflection on the front surface (concave surface) of the reflecting mirror 15, and then refracted by the lens 14, for example, in a stage or a studio. A predetermined area is irradiated. Hereinafter, an area that is brightly illuminated by the light, which is formed on an illumination target such as a stage or a studio by irradiating the spotlight, is referred to as a light irradiation area.

As the concave reflecting mirror 15, for example, a spherical reflecting mirror is used. Instead of the spherical reflecting mirror, a known concave reflecting mirror such as an ellipsoidal reflecting mirror or a parabolic reflecting mirror can be used.

As the lens 14, for example, a convex lens is used. A known lens such as a Fresnel lens can be used in place of the convex lens.

In the spotlight 10 of the present invention, the concave reflecting mirror 15 and the socket 17 are supported by a movable support 18 provided on the wall surface of the lid body 13 on the cylinder body 11 side so as to be movable in the longitudinal direction of the cylinder body. It is fixed. The concave reflecting mirror 15 is provided on a supporting plate 28 of the movable supporting member 18 described later, for example, supporting

materials

24a and 24b (the supporting material on the nearer side of the paper of FIG. 3 than the reflecting mirror 15 is illustrated). Is not fixed).

The movable support 18 is rotatably attached to guide

shafts

25a and 25b fixed to the lid body 13, bushes (bearings) 26a and 26b slidably fitted around the respective guide shafts, and the lid body 13. And a support plate 28 fixed to the

bushes

26a, 26b and the nut 27b. The feed screw 27 includes a screw shaft 27a and a nut 27b fitted to the screw shaft 27a.

Since the

bushes

26a and 26b can slide along the

guide shafts

25a and 25b, respectively, the support plate 28 can move along the length direction of the guide shaft (corresponding to the longitudinal direction of the cylinder 11). is there. Then, by turning a knob 29 provided at the rear end portion of the screw shaft 27a of the feed screw 27, the support plate 28 and the nut 27b are aligned with the length direction of the screw shaft 27a (the front-rear direction of the cylinder 11). Can be moved along. By moving the support plate 28, the light bulb 16 and the concave reflecting mirror 15 can be moved in the front-rear direction of the cylindrical body 11.

The mechanism for moving the support plate 28 in the front-rear direction of the cylindrical body 11 is not particularly limited. For example, a ball bush (ball bearing) is used as each of the

bushes

26a and 26b, or a ball screw is used as the feed screw 27. You can also. Moreover, you may move the support plate 28 using a well-known linear motion drive device, without using the said

bushes

26a and 26b and the feed screw 27. FIG.

Then, by using the movable support 18 to move the light bulb 16 and the concave reflecting mirror 15 to the front side or the rear side of the cylindrical body 11, the light irradiation area of the spotlight 10 can be enlarged or reduced. . For example, the light irradiation region of the spotlight 10 can be expanded by moving the light bulb 16 and the concave reflecting mirror 15 forward from the position indicated by the solid line in FIG. 3 to the position indicated by the two-dot chain line.

Further, by accommodating, for example, a color filter in the accommodating portion 52a and / or the accommodating portion 52b formed at the front end of the cylindrical body 11, the light color of the spotlight 10 can be set to various colors. In addition to the filter, various dimming devices (eg, a mechanically driven multicolor filter) can be attached to the housing 52a.

At the rear end of the cylinder 11, a lid 13 that can be opened and closed with the rear portion of the cylinder 11 as a fulcrum 12 is provided. The lid 13 is provided with a temporary fastener 34 that can be inclined and moved with a shaft 33 provided on the lid 13 as a fulcrum. By engaging the protrusion 34a formed on the front side of the temporary fastener 34 with the protrusion 11a protruding inward from the rear end of the cylindrical body 11, the lid body 13 is prevented from being inadvertently opened. be able to.

Further, in the state where the movable support 18 is moved forward, the presser plate 41 is disposed directly below the lower end portion 34c of the temporary fixing tool 34, so that the temporary fixing tool 34 cannot be inclined and moved. The lid 13 cannot be opened. That is, the lid 13 is configured so that it can be opened only when the movable support 18 is disposed on the most rear side together with the reflecting mirror 15. This is because when the lid 13 is opened with the reflecting mirror 15 disposed on the front side, the reflecting mirror 15 comes into contact with the inner wall surface of the cylindrical body 11.

Then, when the temporary fastener 34 is pushed up and disposed at the position indicated by the two-dot chain line in FIG. 3, the engagement between the projection 34a and the projection 11a is released, so that the lid The body 13 can be opened by pulling the handle 35 backward.

FIG. 6 is a diagram showing the spotlight 10 in a state where the lid 13 is half-opened, and FIG. 7 is a diagram showing the spotlight 10 in a state where the lid 13 is fully opened.

As shown in FIG. 7, when the lid 13 of the spotlight 10 is fully opened, the light bulb 16 is disposed outside the cylinder 11. For this reason, the maintenance of the light bulb 16 can be easily performed. For example, wiping off dirt (eg, dust) attached to the tube 16a of the light bulb 16 or replacing the light bulb 16 when the filament 16c is disconnected can be performed easily and in a short time.

Further, when the lid 13 of the spotlight 10 is fully opened, the concave reflecting mirror 15 is also disposed outside the cylinder 11 together with the light bulb 16. For this reason, maintenance of the concave reflecting mirror 15 can also be easily performed. For example, dirt adhering to the front surface (concave surface) of the concave reflecting mirror 15 can be easily and quickly wiped off.

Furthermore, when the lid 13 of the spotlight 10 is fully opened, the concave reflecting mirror 15 is taken out of the cylinder 11, thereby forming a wide working space on the rear side of the lens 14 inside the cylinder 11. For this reason, the maintenance of the lens 14 can be easily performed. For example, by putting a hand into the inside of the cylinder 11 from the opening on the rear side of the cylinder 11, dirt attached to the surface on the rear side of the lens 14 can be wiped off easily and in a short time. Further, after removing the bolt 36 that fixes the lens 14, the lens 14 can be taken out from the opening on the rear side of the cylindrical body 11 and cleaned. The maintenance work of these lenses can be easily performed without removing the concave reflecting mirror 15.

Note that the lens 14 of the spotlight 10 is supported by an annular support 37 that opens around the lens 14 with a diameter smaller than the outer diameter of the lens 14. For this reason, even if the lens 14 is suddenly removed when removing the bolt 36 as described above, the lens 14 does not jump out of the opening on the front side of the cylindrical body 11 and fall. Therefore, the lens 14 can be safely taken out of the cylindrical body 11. Instead of using the annular support 37, for example, a net is stretched in front of the lens inside the cylinder 11, or the inner diameter of the portion of the cylinder 11 in front of the lens 14 is set to be smaller than that of the lens 14. The lens can also be prevented from falling by making it smaller than the outer diameter.

As described above, in the spotlight 10 of the present invention, maintenance of all the main components, that is, the light bulb 16, the concave reflecting mirror 15, and the lens 14 can be performed easily, in a short time, and safely. In particular, in the spotlight of the present invention, the maintenance of the lens 14 and the concave reflecting mirror 15 can be performed easily and in a short time without removing the concave reflecting mirror 15. For this reason, maintenance of the lens 14 and the concave reflecting mirror 15 can be performed frequently. Therefore, the spotlight 10 of the present invention can be used particularly advantageously in a stage or a studio where a stable and high light quantity is required over a long period of time.

As shown in FIG. 3, in the spotlight 10 of the present invention, the front end of the concave reflecting mirror 15 is in a state in which the movable support 18 is moved most backward (the reflecting mirror 15 is disposed at a position indicated by a solid line in the figure). The cylinder 11 and the lid 13 are the inner wall surface of the cylinder 11 and the front end of the reflecting mirror 15 and the rear of the cylinder 11. It is preferable that they are connected to each other via a connecting tool 19 that can be inclined and moved with the position between the ends as a fulcrum 12.

As shown in FIG. 8, as the connection tool 19, a known hinge including a substrate 19 a that rotatably supports a shaft (12) constituting the fulcrum 12 and a movable arm 19 b fixed to the shaft is used. It has been.

As shown in FIG. 6, when the fulcrum 12 is arranged on the inner wall surface of the cylindrical body 11 and between the front end of the reflecting mirror 15 and the rear end of the cylindrical body 11, the diameter of the cylindrical body 11 is reduced. The Nawa spotlight 10 can be downsized. For example, the radius of rotation (Ra) of the top of the reflecting mirror 15 centered on the fulcrum 12 is the top of the reflecting mirror 15 centered on the position of the rear end of the cylindrical body 11 (position indicated by X in the figure). Smaller than the radius of rotation (Rb). For this reason, when the fulcrum 12 is arranged at a position between the front end of the reflecting mirror 15 and the rear end of the cylindrical body 11, the top of the reflecting mirror 15 moves along the arrow 38a shown in the figure. Even when the diameter is small, the reflecting mirror 15 can be taken out from the opening on the rear side of the cylindrical body 11. On the other hand, when the fulcrum is disposed at the position of the rear end of the cylindrical body 11 (the position indicated by X in the drawing), the top of the reflecting mirror 15 moves along the arrow 38b. Unless the value is set to a larger value, the reflecting mirror 15 cannot be taken out from the opening on the rear side of the cylindrical body 11. The “inner wall surface of the cylinder” includes a surface of another component (for example, the ventilator 39b) installed on the inner wall surface.

As shown in FIG. 6, when the distance between the front end of the reflecting mirror 15 and the rear end of the cylinder 11 is La, the distance Lb between the fulcrum 12 and the rear end of the cylinder 11 is 0.1 La to 0. It is preferably set to a value within the range of 5 La. The longer the distance Lb is, the smaller the radius of rotation of the top of the reflecting mirror 15 is. Therefore, the diameter of the cylindrical body 11 can be set to a small value (that is, the size of the spotlight 10 can be reduced). However, if the distance Lb is too long, the radius of rotation of the bottom of the reflecting mirror 15 decreases, and the bottom of the reflecting mirror 15 may come into contact with the inner wall surface of the cylinder 11 when the lid 13 is opened. .

In the spotlight 10 of the present invention, on the front side of the lens 14, four

light shielding plates

42 a, 42 b, 42 c, 42 d that can protrude inside the periphery of the lens 14 are arranged along the periphery of the lens 14. It is preferable that it is disposed.

The cylinder 11 of the spotlight 10 includes an outer cylinder 51a and an inner cylinder 51b fitted inside the front end portion of the outer cylinder 51a. The four light shielding plates are attached to the inner cylinder 51b.

Hereinafter, the configuration and operation of the light shielding plate will be described using the light shielding plate 42a shown in FIG. 5 as an example.

The shading plate 42a is provided with a handle 43 that extends through the cylindrical body 11 to the outside. Before and after the handle 43, L-shaped

supports

44a and 44b fixed to the inner cylinder 51b are disposed. The

support tools

44a and 44b are fixed to each other by bolts 45 with a spacer 46 interposed therebetween.

The support tool 44b includes a handle support plate 47 at the center in the width direction. The handle support plate 47 is bent at an upper portion thereof, and a protruding portion 47a is formed on the handle 43 side. The arrangement of the handle 43 is fixed by being sandwiched between the support tool 44a and the protruding portion 47a. By manipulating the tip of the handle 43 by hand, for example, the light shielding plate 42a is moved in the radial direction of the lens (vertical direction in the light shielding plate 42a) or tilted (for example, shown by a two-dot chain line in FIG. 5). Can be moved). The handle 43 is moved to the side of the lens 14 (downward). When the stopper 48 provided at the tip of the handle 43 comes into contact with the support tool 44a, the handle 43 is further prevented from moving to the lens side. The light shielding plate can also be driven using a driving device.

The moving range of the light shielding plate 42 a can be adjusted by changing the length of the handle 43, the size of the hole 51 c of the inner cylinder 51 b through which the handle 43 passes, or the interval between the handle 43 and the spacer 46. The

light shielding plates

42a and 42b shown in FIG. 1 are moved to the lens 14 side most, and the

light shielding plates

42c and 42d are moved to the opposite side from the lens side. It is filled in. Further, when the light shielding plate is moved to the lens 14 most, the lens 14 is arranged so that light does not leak to the side opposite to the lens 14 side of the light shielding plate (for example, the light shielding plate 42a shown in FIG. 1). A light shielding ring 49 is provided in front of the lens. This light shielding ring may be provided in front of the

light shielding plates

42a, 42b, 42c, 42d.

Then, one or more of the four

light shielding plates

42a, 42b, 42c, and 42d shown in FIG. 1 are moved to the lens side (extruded to the inner periphery of the lens), and the lens is moved. By blocking the transmitted light, the shape of the light irradiation region formed on the illumination object by the light of the spotlight can be changed. For example, when the spotlight 10 is used for stage lighting, by moving the light shielding plate 42b to the lens side, the shape of the light irradiation area formed by the spotlight is not irradiated to the audience seat in front of the stage. The shape can be set. Further, by moving the light shielding plate 42c or the light shielding plate 42d toward the lens, the shape of the light irradiation region can be set to a shape in which light is not irradiated to the sleeves of the stage.

Each light shielding plate is made of, for example, stainless steel. In order to suppress reflection of light by the light shielding plate, it is preferable to coat the light shielding plate in black. The number of light shielding plates is not particularly limited, but if the number of light shielding plates is large, the configuration of the spotlight becomes complicated, and the operation of the light shielding plates is troublesome. For this reason, the number of light shielding plates is preferably in the range of 2 to 8 (particularly 2 to 4).

In the spotlight 10, maintenance of all of its main parts, that is, the light bulb 16, the concave reflecting mirror 15, and the lens 14 is maintained without moving the light shielding plate, that is, the light irradiation area of the spotlight is maintained in an appropriate shape. Can be carried out easily and in a short time. For this reason, the troublesome work of moving the light shielding plate again after the completion of the maintenance and resetting the light irradiation area of the spotlight 10 to an appropriate shape is not required. A spotlight having such a light-shielding plate is particularly advantageously used in a stage or a studio where a stable and high amount of light is required over a long period of time and the shape of the light irradiation area needs to be changed. be able to.
