Abstract
The utility model provides a flash lamp. The flash lamp comprises a housing, a motor, a lamp cup frame, a lamp cup and a lamp tube, wherein the motor and the lamp cup frame are arranged inside the housing; the lamp cup is fixedly arranged inside the lamp cup frame; the lamp tube is fixedly arranged inside the lamp cup; a screw rod rotating along with a rotating shaft is arranged on the rotating shaft of the motor; the lamp cup frame is arranged on the screw rod in a slidable manner; a shaft lever is arranged on a shaft seat; the shaft seat is fixedly arranged inside the housing; the ring-shaped part of a spring formed by a steel wire is sleeved inside thread seam of the screw rod; and the two ends of the spring are respectively connected and fixed on two sides of the lamp cup frame. In the flash lamp provided by the utility model, an electric zoom lens control device can drive the flash lamp cup inside the flash lamp to move forwards or backwards under the coordination of the motor, the screw rod mounted on the motor and the spring sleeved on the screw rod, besides, the flash lamp has the advantages of simple structure, stability and durability, as well as quiet operation.
Description
Technical field
The utility model relates to the camera flashlamp technical field, the particularly a kind of flashlamp that can be realized power zoom by microcomputerized control.
Background technology
Need to install the portable flash lamp on the camera, because the power supply (battery) that brightness of flash lamp can be carried by the user is limit, the range of exposures that need make light is the coverage of overlaid camera just, reaches to increase farthest illumination distances and save the electric energy purpose.This needs the light-illuminating scope of flashlamp to change and to change along with lens focus, and the light-illuminating scope change of ordinary flash lamp is called zoom.Prior art generally realizes the change of light-illuminating scope by stirring the Lamp cup that flash lamp tube is installed manually, prior art needs artificial the participation, range of application is restricted, particularly light is being required than higher occasion, photographer often changes lens focus, need flashlamp to stretch together along with camera lens, and can obtain the focal length of camera lens by the micro computer coding from camera, therefore, in order to realize that the light-illuminating scope adapts to coverage automatically, make photographer more be absorbed in photograph taking, needs are a kind of can be by the power zoom device of microcomputerized control.
The utility model content
The utility model provides a kind of flashlamp that can be realized power zoom by microcomputerized control, adapts to coverage automatically to realize the light-illuminating scope.
To achieve these goals, the utility model provides following technical scheme:
A kind of power zoom device of flashlamp, it is characterized in that, comprise: casing, the motor that is installed in described casing inside, Lamp cup frame, be installed on the Lamp cup in the described Lamp cup frame and be installed on fluorescent tube in the described Lamp cup, be equiped with screw rod in the rotating shaft of described motor along with described rotating shaft rotation;
Described Lamp cup frame slidably is installed on the axostylus axostyle, described axostylus axostyle is installed on the axle bed, described axle bed is fixedly installed in the casing, and the circle portion by the spring that a steel wire forms is enclosed within the described screw flight seam, and the two ends of described spring connect and be fixed on the both sides of Lamp cup frame respectively.
Wherein, preferred, described axostylus axostyle is two, and the both sides of described Lamp cup frame are provided with circular hole, and described Lamp cup frame slidably is through on the described axostylus axostyle by described circular hole.
By above technical scheme as can be seen, the flashlamp that the utility model provides at motor, be installed in the screw rod on the motor, and be enclosed within the cooperation of the spring on the screw rod, the flash of light Lamp cup that can drive in the flashlamp moves forward or backward, and simple in structure, steadily durable, operation peace and quiet.
Description of drawings
The structural representation (stereographic map) of the flashlamp that Fig. 1 provides for the utility model embodiment;
The flashlamp vertical view that Fig. 2 provides for the utility model embodiment.
Embodiment
In order better to understand the technical solution of the utility model, describe the embodiment that the utility model provides in detail below in conjunction with accompanying drawing.
The utility model embodiment provides a kind of flashlamp, as depicted in figs. 1 and 2, comprise the power zoom device, this power zoom device is installed in the flashlamp, this flashlamp comprises: casing 100, the motor 101 that is installed in described casing 100 inside, Lamp cup frame 105, be installed on the Lamp cup 107 in the described Lamp cup frame 105 and be installed on fluorescent tube 106 in the described Lamp cup 107, this light 106 is used for flash of light, is equiped with the screw rod 102 along with described rotating shaft rotation in the rotating shaft of described motor 101;
Described Lamp cup frame 105 slidably is installed on the axostylus axostyle 104, described axostylus axostyle 104 is installed on the axle bed 108, described axle bed 108 is fixedly installed on 100 li of casings, circle portion by the spring 103 that a steel wire forms is enclosed within the screw thread seam of described screw rod 102, and the two ends of described spring 103 connect and be fixed on the both sides of Lamp cup frame 105 respectively.When camera lens stretches out forward or during indentation, be subjected to the control of microcomputer controlling module, this motor 101 just changes thereupon or reverses, drive screw rod 102 is just changeing or is reversing, the spring 103 that is enclosed within on the screw rod 102 moves forward or retreats in the screw thread seam of screw rod 102, drive Lamp cup frame 105 advances or retreats, thereby drive fluorescent tube 106 advances or retreats, and the final change flashlamp light-illuminating scope that realizes is with shot change.
Wherein, concrete, described axostylus axostyle 104 is two, and the both sides of described Lamp cup frame 105 are provided with circular hole, and the both sides of described Lamp cup frame 105 slidably are through on the described axostylus axostyle 104 by described circular hole.
More than a kind of flashlamp that the utility model embodiment is provided be described in detail, for one of ordinary skill in the art, thought according to the utility model embodiment, part in specific embodiments and applications all can change, in sum, this description should not be construed as restriction of the present utility model.
