LED lights can not only provide lighting effects that are closer to natural light, but also achieve precise adjustment of light through intelligent control systems to meet the lighting needs of different scenes and times.

[0003] However, currently available lighting lamps can only provide a single lighting brightness when used indoors. Even if the brightness of the lamp can be intelligently controlled by a controller, it can only adjust the illumination brightness in the room synchronously, and cannot meet the personalized needs of different areas and users in the room. For example, it is impossible to independently adjust the brightness of different areas in the same room to achieve locally bright and locally dim lighting effects, thereby reducing the user experience.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figures 1 to 8 The present invention provides a technical solution: an indoor air purification lamp, comprising a lamp holder 1 and a lampshade 2 which can be assembled and installed together, the lampshade 2 is composed of a fixing part 3 and a light-transmitting part 4 with an arc surface design at the bottom, and also includes;

[0032] A lighting assembly installed in the lampshade 2, the lighting assembly includes a lamp bead 13, and also includes a spherical cover wrapped around the periphery of the lamp bead 13, and the spherical cover can be opened or closed;

[0033] A control unit, which is used to adjust the position of the lighting assembly in the space of the lampshade 2 to change the distance between the lamp beads 13 and various locations of the light-transmitting portion 4;

[0034] The light-transmitting portion 4 and the spherical cover are both made of electrochromic materials, and can be switched between transparent and semi-transparent.

[0035] When the indoor air purifier lamp is in use, during normal lighting use, the position of the lighting assembly is adjusted by the control unit so that it is located at the center of the lampshade 2, and the light-transmitting portion 4 is switched to a transparent state through an external control system. In this way, since the lamp bead 13 is located in the middle of the lampshade 2, the lighting light it emits is in a uniform projection state, which can make the illumination brightness of various areas in the room more uniform and meet people's normal lighting needs. Among them, the spherical cover can be switched to a translucent state or a transparent state according to the required situation to meet different brightness, wherein the translucent state is preferred, so that the light transmitted through it can be softer and more uniform, so as to reduce the glare and glare caused by the lamp bead 13;

[0036] Moreover, in addition to satisfying different brightness requirements by switching the transparent state of the transparent cover, the brightness of the lamp can also be adjusted by opening or closing the spherical cover, wherein the lamp bead 13 preferably adopts a full-spectrum eye protection lighting system to provide healthier light and reduce eye fatigue and visual discomfort;

[0037] When it is necessary to create different lighting effects in different areas of the room, that is, when the room is partially bright and partially dimly lit, for example, when the viewing area in the same room needs a relatively dim environment to achieve a better viewing effect, while another area needs relatively bright lighting, the light-transmitting portion 4 can be switched to a semi-transparent state through an external control system, and then the lighting assembly can be controlled to change its position in the lampshade 2 to change the distance between the lamp beads 13 and each position of the light-transmitting portion 4. For details, please refer to Figure 5 and Figure 7 As shown, as the position of the lamp bead 13 is adjusted, the intensity of the light emitted by it will be affected when passing through the translucent light-transmitting portion 4. The closer the light-transmitting portion 4 is to the lamp bead 13, the better the light-transmitting effect, so that the irradiated area corresponding to the position will be brighter. On the contrary, the farther the light-transmitting portion is from the lamp bead 13, the lower the light-transmitting effect will be, so that the corresponding irradiated area will become dim.

[0038] In this way, by switching the light-transmitting state of the light-transmitting portion 4 and adjusting the position of the illumination component (i.e., the lamp bead 13) in the lampshade 2, different illumination areas can be created in the same room to achieve local bright and local dim lighting effects, thereby improving the user experience.

[0039] Moreover, it is worth mentioning that such an integrated design can not only reduce the number of lamps, but also ensure that the position of the lamp will not change significantly (that is, if the lamps are designed in two areas separately, when the lamps in different positions are turned on, the position of the entire indoor lamp will change). This can not only reduce the mutual influence of the illumination areas between two or even three lamps, but also, due to the translucent state, the light transmittance will change synchronously with the increase of the distance between the lamp bead 13 and the light-transmitting part 4, so that there will not be too obvious shadow dividing lines between the bright and dim areas, so that users can experience two lighting experiences without isolation in the same room, further improving the user experience.

[0040] In one of the more preferred embodiments, an implementation of a control unit is provided;

[0041] The control part includes a rotating shaft 7 which is installed at the center of the lamp holder 1 and can rotate. An arc frame 8 is fixed to the bottom end of the rotating shaft 7, and the bottom surface of the arc frame 8 is set to be an arc surface with the same arc as the light-transmitting part 4. An adjustment block 9 which can slide and adjust along its arc surface is installed on the bottom arc surface of the arc frame 8. A mounting rod 12 which is coaxially arranged with the rotating shaft 7 is fixed to the bottom of the adjustment block 9, and the lamp bead 13 is installed at the bottom of the mounting rod 12.

[0042] For details, please refer to Figure 3 and Figure 5 In the above normal use state, the adjustment block 9 is located in the middle of the arc frame 8, that is, Figure 3 In the state shown, the lamp bead 13 is located in the middle of the lampshade 2, so that the irradiation range can be more uniform;

[0043] When it is necessary to adjust the brightness of the illuminated area, the adjustment block 9 can be controlled by the external structure to slide and adjust on the arc surface at the bottom of the arc frame 8 to change the position of the lamp bead 13 in the lampshade 2, thereby achieving the above-mentioned purpose of changing the illumination brightness in different areas to achieve local bright and local dim lighting effects, and the rotating shaft 7 can also be driven to rotate by the external structure to drive the arc frame 8 to rotate, so as to adjust the position of the lamp bead 13 in the space of the lampshade 2, and then adjust the corresponding illumination area.

[0044] In one of the more preferred embodiments, an implementation method of opening or closing the spherical cover is provided;

[0045] The spherical cover includes a plurality of arc covers 16 installed on the outer wall of the mounting rod 12 through a soft connection part, and the plurality of arc covers 16 can be combined into a spherical space that wraps the lamp bead 13. A sliding ring 14 is slidably installed on the outer wall of the mounting rod 12, and a connecting rod 15 is rotatably connected between the sliding ring 14 and each arc cover 16. An electromagnet 17 is installed at the bottom of the adjustment block 9, and a magnetic ring that can cooperate with the electromagnet 17 is installed on the outer wall of the sliding ring 14. A spring 18 is also connected between the electromagnet 17 and the sliding ring 14.

[0046] For details, please refer to Figure 3 and Figure 4 By controlling whether the electromagnet 17 is energized or not, and then cooperating with the spring 18 and the magnetic ring on the sliding ring 14, the purpose of controlling the sliding ring 14 to move up and down can be achieved. When the sliding ring 14 moves up, under the connecting action of the connecting rod 15, the arc cover 16 will rotate upward along the soft connection part to open, thereby exposing the lamp bead 13, so that the light can be directly irradiated on the translucent light-transmitting part 4, so as to reduce the influence of the arc cover 16 on the light penetration;

[0047] On the contrary, when the sliding ring 14 moves downward, the arc cover 16 can be closed by the connecting rod 15 to form a spherical space with the lamp bead 13 at the center of the sphere, so that the light can pass through the arc cover 16 more evenly to ensure the illumination effect under normal conditions.

[0048] In one of the more preferred embodiments, an implementation method capable of adjusting the light transmission state of the light-transmitting portion 4 and the spherical cover is provided;

[0049] Two trigger switches 19 are installed on the outer wall of the mounting rod 12, and the two trigger switches 19 are electrically connected to the electric control system for controlling the light-transmitting portion 4 and the spherical cover respectively. When the sliding ring 14 is adjusted to slide vertically, it will contact and trigger one of the trigger switches 19.

[0050] For details, please refer to Figure 3 When the sliding ring 14 slides up and down, it will contact one of the trigger switches 19, and then the trigger switch 19 will control the corresponding light-transmitting part 4 or the electrical control system of the spherical cover to control the voltage state of the electrochromic material, thereby changing its optical properties. After the trigger switch 19 is separated from the sliding ring 14, the material can return to its initial state when the voltage is removed. Therefore, both the light-transmitting part 4 and the spherical cover can be switched between transparent and translucent states.

[0051] In one of the more preferred embodiments, an implementation for controlling the position of the adjustment block 9 is provided;

[0052] An arc-shaped rack 10 is fixed to the arc-shaped outer wall of the arc-shaped frame 8, a hollow groove is opened inside the adjusting block 9, and a worm 11 is rotatably installed in the hollow groove. The worm 11 is meshed with the arc-shaped rack 10, and a micro servo motor for driving the worm 11 to rotate is also embedded inside the adjusting block 9.

[0053] For details, please refer to Figure 4 and Figure 6 The micro servo motor in the adjustment block 9 can drive the worm 11 to rotate, and the meshing transmission between the worm 11 and the arc rack 10 can drive the adjustment block 9 to slide along the arc surface of the arc frame 8 to change the position of the adjustment block 9, and then cooperate with the rotation of the above-mentioned rotating shaft 7 to achieve the purpose of adjusting the position of the lamp bead 13 in the lampshade 2.

[0054] In one of the more preferred embodiments, an arc-shaped slide groove 21 is provided on the side wall of the arc frame 8, and a slider 22 slidably installed in the arc-shaped slide groove 21 is fixed to the outer wall of the adjustment block 9; by utilizing the sliding cooperation between the arc-shaped slide groove 21 and the slider 22, the adjustment of the adjustment block 9 can be made more stable.

[0055] In one of the more preferred embodiments, a control part 5 is further installed at the connection between the fixing part 3 and the light-transmitting part 4 , and the control part 5 is electrically connected to the corresponding trigger switch 19 for adjusting the voltage state of the light-transmitting part 4 .

[0056] In one of the preferred embodiments, a servo motor for driving the rotating shaft 7 to rotate and adjust is installed on the top plane of the lamp holder 1, and the output shaft of the servo motor is connected to the rotating shaft 7 through a gear reducer; see Figure 3 and Figure 4 The servo motor can drive the rotating shaft 7 to rotate through the reducer to finely adjust the position of the lamp bead 13 to meet the user's experience.

[0057] In one of the more preferred embodiments, a negative ion generator 6 is installed on the top plane of the lamp holder 1, and a notch is provided on the outer wall of the lamp holder 1 to allow the negative ion generator 6 to contact the external environment.

[0058] Negative ions can be generated by the negative ion generator 6 to improve the quality of indoor air, reduce suspended particles in the air, kill bacteria and viruses in the air, and purify the indoor air environment. Since it is located above the lamp holder 1, the air flow nearby will be more obvious while the lamp is dissipating heat, which is more conducive to the diffusion of negative ions and improves the purification effect.

[0059] In one of the more preferred embodiments, a plurality of groups of heat dissipation fins 23 are fixed to the top plane of the lamp holder 1 , and the heat dissipation fins 23 are flush with the edge plane of the lamp holder 1 .

[0060] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and the drawings can also be directly processed according to the existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0061] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
