Description

Technical Field

[0001] The utility model relates to the technical field of LED desk lamp equipment, in particular to a switch control structure of an LED desk lamp. Background Art

[0002] With the development of science and technology and people's pursuit of quality of life, LED desk lamps have gradually become common lighting equipment in homes and offices due to their advantages of energy saving, environmental protection, long life and soft light. However, although the application of LED technology in the field of lighting is quite mature, the existing LED desk lamps still have some inconveniences when used.

[0003] However, due to the limitations of the lampshade design, many existing LED desk lamps have fixed lampshades that cannot be adjusted during use. This results in the user being unable to adjust the range of light source exposure according to their reading, work or rest needs during use. For example, when a user needs to work at a desk for a long time, a fixed lampshade may not provide enough light coverage, causing eye fatigue, while when reading or studying, the light needs to be more concentrated.

[0004] In view of the above problems, it is urgent to carry out innovative design based on the original desk lamp switch control. Utility Model Content

[0005] The technical solution of the utility model aims at the technical problem that the existing technical solution is too single, and provides a solution with a switch control structure of an LED desk lamp that is significantly different from the existing technology, so as to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an LED desk lamp switch control structure, comprising a base, one side of the base is connected to a pressure switch structure triggered by pressure, and a support frame is installed on the top of the base, and an adjustment threaded rod is rotatably connected between the bottom of the upper end of the support frame and the top of the base, the outside of the adjustment threaded rod and the outer cover of the support frame are provided with a mounting sleeve, and the mounting sleeve is connected to a mounting plate near the side of the pressure switch structure, the bottom of the mounting plate is connected to a lamp holder, and an LED lamp is installed on the lamp holder, and a light adaptation structure for adjusting the lighting range is provided between the support frame, the mounting plate and the lamp holder.

[0007] Preferably, the pressure switch structure includes a lower concave plate, an upper concave plate, a reset spring, a trigger block, and a limit switch. The base is connected to the lower concave plate, and the upper concave plate is sleeved on the lower concave plate. A number of reset springs are provided between the lower concave plate and the upper concave plate, and the bottom of the upper concave plate is connected to the trigger block. A limit switch cooperating with the trigger block is installed in the lower concave plate, and the limit switch is electrically connected to the lamp holder.

[0008] Preferably, the mounting sleeve is slidably connected to the support frame, and the mounting sleeve is threadedly connected to the adjusting threaded rod.

[0009] Preferably, the lighting adaptation structure includes a groove, a connecting shaft, a concave block, a vortex spring, an adjustment plate, a protruding bead, a connecting wire, a first magnetic block, a mounting tube, and a second magnetic block. A groove is provided on each side of the lamp holder, and one end of each groove is rotatably connected to a connecting shaft, and the other end of each connecting shaft is located in the corresponding concave block, and the concave block is connected to the other end in the groove, and a vortex spring is connected between each groove and the end of the connecting shaft, an adjustment plate is connected to the outer wall of each connecting shaft, and a connecting wire is connected to the outer side of each adjusting plate, and each end of the connecting wire passes through the mounting plate and is connected to the first magnetic block, and the first magnetic block is located in the mounting tube at the top of the mounting plate, and a second magnetic block for cooperating with the first magnetic block is connected to the support frame.

[0010] Preferably, a plurality of transparent protruding beads for reflecting and refracting light are densely arranged on the inner wall of each adjustment plate close to the lamp holder.

[0011] Preferably, the first magnetic block and the mounting cylinder are in a snap-fit ​​sliding connection.

[0012] Compared with the prior art, the beneficial effect of the utility model is as follows: the switch control structure of the LED desk lamp, through the setting of the pressure switch structure, when the user is writing or reading, the gravity of the book will act on the upper concave plate, causing it to move down and fit the lower concave plate, this action will cause the reset spring to be compressed, and at the same time the trigger block contacts the limit switch, the limit switch sends a signal, and this signal is processed by the PLC control board in the base, and the PLC control board controls the LED lamp holder to form a closed circuit according to the signal, so that the LED lamp lighting works, and since this process does not require an additional control switch, the device has a certain intelligence and can realize automatic lighting.

[0013] Through the arrangement of the support frame, the adjusting threaded rod, the mounting sleeve, the mounting plate and the light adaptation structure, when a large-scale lighting is required, the adjusting threaded rod should be rotated clockwise first. As the threaded rod rotates, the mounting sleeve and the mounting plate will move up. At this time, the first magnetic block and the second magnetic block will approach and attract each other to ensure that the distance between them is appropriate. In the mounting tube, the upward movement of the first magnetic block will pull the connecting wire. At the same time, the adjusting plate will rotate through the connecting shaft and open outward. The purpose of this is to reduce the blocked area of ​​the LED lamp, so that the LED lamp can greatly improve the lighting range in both cases of raising and expanding the lampshade to reduce the blockage.

[0014] By placing several transparent raised beads on the adjustment plate, the light can be refracted and scattered in the light path of the LED lamp, thereby achieving the effect of enhancing the light intensity. These raised beads are usually made of transparent or translucent materials, such as glass, plastic or special optical resin. They can refract the light emitted by the LED lamp at different angles, making the light more evenly distributed in the space, thereby improving the brightness and uniformity of the lighting.

[0026] The first magnetic block 908 and the mounting tube 909 are in a snap-fitting sliding connection.

[0027] Working principle: According to Figure 1 As shown, firstly, a book is placed on the upper concave plate 202. Under the action of gravity, the upper concave plate 202 moves to fit the lower concave plate 201, the return spring 203 is compressed, the trigger block 204 contacts the limit switch 205, and the limit switch 205 sends a signal.
