Abstract
The utility model relates to a high-efficient focusing device for a light projecting lamp, which is characterized in that the utility model is composed of chassis 1 with an adjusting movable nut 6, an adjusting screw 5 with a rotary hand wheel 4, a movable supporting frame 10 with a movable shaft 9, and a front disk 7 with an adjusting movable nut 8. The adjusting movable nut on the front disk is impelled to move up and down, and the focusing device is led to open and close through rotating the adjusting screw to drive the movable supporting frame and the adjusting movable nut on the chassis. Then, the purposes of adjusting light beams and focal length can be achieved.
Description
The utility model relates to a kind of Projecting Lamp focus control.
The Projecting Lamp that uses can only send the constant intensity light beam at present, and illumination zone can not be adjusted on demand.
The purpose of this utility model provides a kind ofly can adjust the Projecting Lamp focus control of light beam width and irradiated area size at any time on demand, thereby reaches the purpose that improves the Projecting Lamp effect.
In order to reach above purpose, the utility model Projecting Lamp focus control is made up of the chassis that has slideway, the shroud that has slideway, distortion support and adjustment screw rod.Modification support two ends embed respectively in the slideway of chassis and shroud; Adjust screw rod and be connected the feeding slideway, flexibly connect with travel(l)ing rest one end with chassis one survey screw thread couple.If screw rod is adjusted in turn at this moment, adjusting screw rod will push-and-pull distortion support and make it distortion, thereby has changed the chassis that is connected in distortion support two ends and the distance between the shroud.If the socket of this device shroud and Projecting Lamp is affixed, the bonnet of chassis and Projecting Lamp is affixed, can reach the light beam width of adjustment Projecting Lamp and the purpose of irradiated area size.
Below in conjunction with the drawings and specific embodiments the utility model is described in further details.
Accompanying drawing is the structural map of a kind of embodiment of the utility model Projecting Lamp focus control.
Projecting Lamp focus control shown in the figure is made up of chassis 1, shroud 7, distortion support 10 and adjustment screw rod 5.Chassis 1 and shroud 7 have slideway; Distortion support 10 two ends embed respectively in the slideway of chassis 1 and shroud 7; In the middle of the distortion support movable axis 9 is arranged; Adjust screw rod 5 one ends rotation hand wheel 4 is housed, the other end and chassis 1 side screw thread coincide; Chassis 1 is affixed by screw 3 with Projecting Lamp afterbody bonnet; Socket 11 is housed on the shroud 7, and socket can be adorned fluorescent tube 12.During use, turn handwheel 4,5 drive adjusting activities female 6 of adjustment screw rod and adjusting activity mother 8 are moved in slideway, distortion support 10 rotates and is out of shape around movable axis 9, thereby drive the socket 11 on the shroud 7, fluorescent tube 12 move left and right, and reach the purpose of adjusting the Projecting Lamp focal length, thus reach the purpose that peace need be adjusted light beam width and irradiated area size.
Claims (1)
1, a kind of efficient Projecting Lamp focus control, it is characterized in that being installed in the general Projecting Lamp afterbody bonnet, form by chassis, shroud, travel(l)ing rest, adjusting activity mother, adjustment screw, the chassis 1 that has adjusting activity mother 6 is fastened on the inboard of the bonnet 2 of light fixture afterbody by screw 3, the adjustment screw 5 that has rotation hand wheel 4 flexibly connects with chassis 1, have movable female 8 the travel(l)ing rest 10 of shroud 7 through having movable axis 9 and chassis 1 flexible connection regulated, socket 11 is housed on the shroud 7, power saving fluorescent lamps 12 is housed on the socket 11.
