Example two
In practice, the lamp is usually mounted high, which makes it very difficult to adjust the focal length of the embodiment in practice. In order to make the focusing structure more operable, it is necessary to enable remote electric focusing. For example, the rotating structure in the first embodiment can be driven by a motor, so as to achieve the effect of controlling and adjusting. As shown in FIG. 8, the ear piece 71A has an internally threaded hole 173 for engaging the threaded rod 90, and the ear piece has a guide rail 714 at its edge for sliding in a guide rail groove inside the lamp. The motor is connected with the screw rod 90 and drives the screw rod 90 to rotate, the motor is controlled by the control circuit, and when the screw rod 90 rotates, the lug 71A which is in threaded engagement with the screw rod 90 is driven to move linearly in the guide rail groove, so that the lens 7 can move horizontally in the direction of the guide rail strip, and the focal length position is changed.
Theoretically, only set up 71A structure to the translation that the motor drive structure can realize the lens, but such setting makes only there is power drive at lens one side, when motor operation drive screw 90 moved, drive 71A through the screw thread and move, and then transmit whole lens structure, adjustable lens structure atress imbalance this moment, cause and adjust the motion unstable, relative slope appears with adjusting the inboard position of knob ring 3 easily, make the thread engagement block to continue to rotate and can not normally adjust the focus, or even just operate and will wear out the screw thread and finally lead to failing. If a plurality of motors are arranged for driving, for example, the motors are arranged at the symmetrical positions of 71A, the problem of unbalanced stress can be avoided, but because the part production inevitably has errors, such as deviation of threads, after assembly, the movement of the driving lug blocks of the plurality of driving structures cannot be completely synchronous, the lens structure still has unbalance, and finally the driving device fails.
Therefore, this embodiment provides a further improved solution, as shown in fig. 9, a pair of support arms 701 is disposed outside the lens 7, and the support arms 701 are respectively disposed at two sides of the lens 7 and symmetrically disposed with respect to each other. The support arm 701 has end portions 702, and as shown in fig. 10, the end portions 702 are slidably connected to the rail grooves 301 on the inner side of the lamp cylinder wall, respectively, and the end portions 702 are linearly movable in the rail grooves 301.
See in particular fig. 10, 11. The driving portion of the lens includes a pair of driven structures, a driving structure, and a stepping structure. Two driven structures are arranged on the inner side of the LED lamp, and the driving device 130 and the stepping structure are arranged on the outer side of the lamp cavity. The driven structure is provided with a connecting rod 111, a first piston 113, a first pipeline 114 and a first cylinder 116; wherein the connecting rod 111 is positioned in the guide rail groove 301, one side of the connecting rod is vertically and fixedly connected with the end part 702, and the other side of the connecting rod is fixedly connected with the first piston 113; the first piston 113 divides the first cylinder 116 into two chambers, which are not communicated with each other; the first cavity 115, which is in communication with the first conduit 114, is filled with a liquid. The driving structure is composed of a second cylinder 134, a second pipeline 131, a second piston 133 and a push rod 135, the second cylinder 134 is divided into two cavity parts by the second piston 133, wherein the second cavity 132 is connected with the two first pipelines 114 through the second pipeline 131 and further respectively communicated with the first cavities 115 of the two driven structures, the second cavity 132, the first cavity 115, the second pipeline 131 and the first pipelines 114 are filled with liquid and are closed, and the push rod 135 is fixedly connected with the third piston 133. As shown in fig. 11, the stepping structure includes a screw 141, a slide table 142, a motor 143, and a guide base 144. The bottom of the sliding table 142 is engaged with the screw 141, and is fixed on the guide base 144 through a bearing support, and the side surface is fixedly connected with the push rod 135. The guide base 144 is fixed to the outer side of the second cylinder 134 to support and guide the slide table 142. The motor 143 is fixed on one side of the guide base 144, and when the motor 143 is started, the screw rod 141 can be driven to rotate, so as to drive the sliding table 142 to move linearly relative to the guide base 144, and the second piston 133 can move linearly forward or backward along with the sliding table through the connected push rod 135. When the second piston 133 moves forward, the first pistons 113 in the pair of driven structures are pushed to move forward respectively due to the constant volume of the liquid in the cavity, and similarly, when the second piston 133 moves backward, the liquid in the cavity generates negative pressure, and the first pistons in the pair of driven structures are pulled to move backward. Because the liquid pressure is the same, the two first pistons 113 are stressed by the same force and can move forwards and backwards synchronously, so that the connecting rod 111 fixedly connected with the first pistons 113 and the guide rail groove 301 move forwards and backwards synchronously, the lens 7 is driven by the two lens supporting arms 701 to synchronously and stably translate, and the focal length of the lens is adjusted.
First cavity 115, firstThe sum V of the volumes of liquid in the conduit 114, the second conduit 131, and the second chamber 132 a Satisfies the following conditions: v a ＝2V max +V t ＝2S 1 ·D max +V t ＝S 2 ·D s ＝V t In which V is max Is the maximum volume reached by the liquid in the first chamber 115 during the driven movement, i.e. the volume reached by the liquid in the first chamber 115, the fourth chamber 125 when the third piston 133 advances to the top of the second cylinder 134, V t Refers to the sum of the liquids in the first and second conduits 114 and 131; s 1 Is the cross-sectional area, D, of the first cylindrical body 116 max Is the maximum stroke of the linear movement of the first piston 113, D max The value of (d) depends on the adjustable range of the lens 7 set, i.e. the range of lengths over which the end 702 can translate in the rail groove 301; s 2 Is the cross-sectional area of second cylinder 134; d s Is the movement stroke setting of the stepping structure. The lens focal length adjustment process is short, and the temperature change has little or negligible effect on the liquid filled in the cavity.
When the volume and the stroke of the liquid filled in the cavity meet the above conditions, and the second piston 133 is driven by the stepping structure to advance to the top of the second cylinder 134, the first piston 113 reaches the maximum position capable of advancing, at this time, the lens end 702 reaches the advance limit position of the guide rail groove 301, and the lens 7 is located at the position of adjusting the maximum distance; when the second piston 133 is driven by the stepping mechanism to move back to the maximum position, the first piston 113 reaches the bottom of the first cylinder 116, and at this time, the lens end 702 reaches the position of the guide rail groove 301 to move back to the maximum position. Therefore, the movement of the end part 702 cannot exceed the allowable range of the guide rail groove, after the stroke of the piston is set, the lens can be regulated and limited only by controlling the volume of the liquid without additionally arranging a limiting structure, so that the structure is more simplified, and the use safety can be ensured.
In operation, since the second chamber 132 and the first chamber 115 are communicated with each other and have the same pressure, the same driving force is generated to the first piston 113, and thus the movement strokes can be synchronized at all times and will not change with the increase of the usage time. Meanwhile, the liquid is communicated to the outer side from the inner side of the lamp and can circularly flow during adjustment, heat generated inside the lamp can be taken out, the temperature of a light source is reduced, and the service life is prolonged.
