[0001] This utility model relates to the field of lighting fixtures, and in particular to an electronically controlled dimming lighting fixture. Background Technology

[0002] Existing lighting fixtures with focusing functions generally use manual focusing or motor-driven light source movement for focusing; however, lighting fixtures that use motor-driven light source focusing have a problem: due to the limitation of motor torque, high-power light sources cannot be used, and good heat dissipation cannot be provided for the light source.

[0003] In view of the above problems, it is necessary to study an electronically controlled dimming lamp that has a focusing function and can use a high-power light source. Utility Model Content

[0004] The purpose of this invention is to provide an electronically controlled dimming lamp that has a focusing function and can use a high-power light source.

[0005] To achieve the above objectives, the solution of this utility model is:

[0006] An electrically controlled dimming lamp includes a lamp body; the lamp body includes a lamp barrel, a light source, a lens assembly, and a focusing assembly; the lamp barrel has a light emission opening, the light source is fixedly installed in the lamp barrel, and the lens assembly is movably installed in the lamp barrel and located between the light source and the light emission opening; the focusing assembly is fitted into the lamp barrel and located on the side of the light source away from the light emission opening; the focusing assembly includes a focusing motor, a focusing screw, and a movable seat, the focusing motor is fixed in the lamp barrel and the output shaft of the focusing motor is connected to the focusing screw, the focusing screw is threadedly connected to the movable seat, the movable seat is slidably fitted with the lamp barrel and the movable seat is connected to the lens assembly.

[0007] The movable seat is connected to the lens assembly via at least three connecting rods.

[0008] The lamp tube is made of metal and has a fixing part inside that is connected to the light source.

[0009] The lamp tube is also provided with an installation opening, and the installation opening and the light emission opening are located at both ends of the lamp tube respectively. The installation opening is fitted with an installation cover, and the focusing component is fitted between the installation cover and the fixing part.

[0010] The lens assembly includes a lens holder and a focusing lens that cooperates with the lens holder, and the lens holder is connected to a movable base.

[0011] The lamp body also includes a reflector tube, which is fixedly installed in the lamp tube and houses the light source. A focusing lens is movably installed in the reflector tube, and a lens bracket is movably installed outside the reflector tube. The lens bracket is connected to the focusing lens through a connector that passes through the reflector tube and slides with the reflector tube. The inner wall of the reflector tube has the ability to reflect light.

[0012] The lamp body also includes an electronic zoom lens fixedly installed in the lamp tube, the electronic zoom lens being located on the light-emitting side of the lens assembly.

[0013] The lamp body also includes a front ring and a fixed ring, with an electronic zoom lens sandwiched between the front ring and the fixed ring, and the light-emitting opening of the lamp tube is fitted with a front cover that limits the front ring and the fixed ring.

[0035] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0036] like Figures 1 to 5 As shown, this utility model discloses an electrically controlled dimming lamp, which includes a lamp body A; the lamp body A includes a lamp barrel 1, a light source 2, a lens assembly 3, and a focusing assembly 4. The lamp barrel 1 has a light emission opening 11. The light source 2 is fixedly installed in the lamp barrel 1. The light source 2 can be COB light 2. The lens assembly 3 is movably installed in the lamp barrel 1 and is located between the light source 2 and the light emission opening 11. The focusing assembly 4 is fitted in the lamp barrel 1 and is located on the side of the light source 2 away from the light emission opening 11. The focusing assembly 4 includes a focusing motor 41, a focusing screw 42, and a movable seat 43. The focusing motor 41 is fixed in the lamp barrel 1 and the output shaft of the focusing motor 41 is connected to the focusing screw 42. The focusing screw 42 is threadedly connected to the movable seat 43. The movable seat 43 is slidably fitted with the lamp barrel 1 and is connected to the lens assembly 3.

[0037] When the lamp body A of this invention is focused, the focusing motor 41 drives the focusing screw 42 to rotate, which in turn drives the movable seat 43 to move. This causes the movable seat 43 to move the lens assembly 3 accordingly, changing the distance between the lens assembly 3 and the light source 2, thereby achieving focusing (i.e., changing the beam angle emitted by the lamp body A). As mentioned above, this invention achieves focusing by moving the lens assembly 3. Therefore, the selection of the light source 2 does not need to consider the torque of the focusing motor 41, allowing the use of a high-power light source.

[0038] In this embodiment of the utility model, the lamp tube 1 may be made of metal. The lamp tube 1 is provided with a fixing part 13 connected to the light source 2, so that the heat generated by the light source 2 can be conducted to the lamp tube 1, effectively reducing the temperature of the light source 2, so that the light source 2 can use a high-power light source. The lamp tube 1 may also be provided with an installation opening 12. The installation opening 12 and the light-emitting opening 11 are respectively located at both ends of the lamp tube 1. The focusing assembly 4 is installed into the lamp tube 1 through the installation opening 12. The installation opening 12 is fitted with an installation cover 121, which can be screwed to the installation opening 12. The focusing assembly 4 is fitted between the installation cover 121 and the fixing part 13. The focusing motor 41 can be fixed to a motor base 44, which is fixedly connected to the lamp tube 1. The movable base 43 can be connected to the lens assembly 3 through at least three connecting rods 5, which movably pass through the fixing part 13 of the lamp tube 1.

[0039] In an embodiment of this utility model, the lens assembly 3 may include a lens holder 32 and a focusing lens 31 that cooperates with the lens holder 32. The lens holder 32 is connected to the movable seat 43 via a connecting rod 5.

[0040] In an embodiment of this utility model, the lamp body A may further include a reflector 6, which is fixedly installed in the lamp tube 1 and houses the light source 2. A focusing lens 31 is movably installed in the reflector 6, and a lens support 32 is movably installed outside the reflector 6. The lens support 32 is connected to the focusing lens 31 through a connector 33 that passes through the reflector 6 and slides with it. The inner wall of the reflector 6 has the ability to reflect light. In this way, part of the light generated by the light source 2 is directly emitted to the focusing lens 31, and the other part is reflected to the focusing lens 31 through the inner wall of the reflector 6, thereby improving the brightness and light efficiency.

[0041] In an embodiment of this utility model, the lamp body A may further include an electronic zoom lens 7 fixedly disposed in the lamp tube 1, the electronic zoom lens 7 being located on the light-emitting side of the lens assembly 3; this utility model can change the shape and size of the light spot emitted from the lamp body A through the electronic zoom lens 7; the electronic zoom lens 7 has a liquid crystal module with a variable refractive index, which can control the light distribution characteristics of the input light in the X-axis and Y-axis directions; by controlling the electronic zoom lens 7 with an electrical signal, the refractive index of the liquid crystal module of the electronic zoom lens 7 is dynamically changed, thereby achieving a zoom function without mechanical movement to adjust the shape and size of the emitted light spot. In addition, the lamp body A also includes a front ring 8 and a fixed ring 9. The electronic zoom lens 7 is sandwiched between the front ring 8 and the fixed ring 9. The fixed ring 9 abuts against the reflector 6. The reflector 6 can abut against the edge of the bracket of the light source 2 to reduce light leakage. The light outlet 11 of the lamp tube 1 is fitted with a front cover 111. The front cover 111 can be screwed to the light outlet 11. The front cover 111 limits the front ring 8, the fixed ring 9 and the reflector 6.

[0042] In embodiments of this utility model, the electrically controlled dimming lamp may further include a drive base B and a swing arm C. The swing arm C is equipped with a first adjusting motor C1 and a second adjusting motor C2. The output shaft of the first adjusting motor C1 is connected to the drive base B, and the output shaft of the second adjusting motor C2 is connected to the lamp tube 1 of the lamp body A. With this configuration, the utility model can drive the lamp body A to rotate relative to the swing arm C via the second adjusting motor C2 and drive the swing arm C to rotate relative to the drive base B via the first adjusting motor C1, thereby flexibly adjusting the illumination position of the lamp body A and making it more flexible to use. The first adjusting motor C1 is used to control the horizontal rotation of the swing arm C, and the horizontal rotation angle can be 0~350°. The second adjusting motor C2 controls the vertical swing of the lamp tube 1, and the swing angle range can be 0~90°.

[0043] In an embodiment of this utility model, the swing arm C may be equipped with a circuit board C3. The circuit board C3 is electrically connected to the light source 2, the focusing motor 41, the electronic zoom lens 7, the first adjusting motor C1, and the second adjusting motor C2, respectively. The circuit board C3 controls the operation of the light source 2, the focusing motor 41, the electronic zoom lens 7, the first adjusting motor C1, and the second adjusting motor C2, respectively. The circuit board C3 may have wireless communication capabilities to communicate with smart terminals (such as smartphones and tablets), allowing users to control the circuit board C3 through an app on the smart terminal. The circuit board C3 can be electrically connected to the light source 2, the focusing motor 41, and the electronic zoom lens 7 via a sliding contact line to ensure that the lamp body A can rotate relative to the swing arm C. The drive base B may be equipped with a drive power supply (not shown), which is electrically connected to the circuit board C3 to supply power. This drive power supply can also be electrically connected to the circuit board C3 via a sliding contact line to ensure that the swing arm C can rotate relative to the drive base B.

[0044] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
