Description

Technical Field

[0001] The utility model belongs to the technical field of lighting, and specifically relates to a practical lighting device. Background Art

[0002] With the rapid development of technology, smart home, as an important trend in future life, is gradually penetrating into our daily life. Among them, smart lamps, as an important part of smart home, their development and innovation are particularly important. However, there are still many deficiencies in the technical maturity and application experience of current smart lamp products on the market.

[0003] Most of the current smart lamps on the market still adopt a direct lighting design. Although this design meets the basic lighting needs to a certain extent, it greatly reduces the softness and comfort of the light. Direct light is often too harsh, easy to cause visual fatigue, and even cause damage to the eyes. Especially in scenarios such as long-term reading, working, or family leisure, this discomfort is particularly obvious. In addition, direct light is also difficult to adapt to the different requirements of light atmosphere in different space environments, restricting the application potential of smart lamps in diverse scenarios.

[0004] Therefore, there is an urgent need for a practical lighting device that can provide soft reflected light, reducing glare and dazzling sensations. Summary of the Utility Model

[0005] In order to solve the above problems, the purpose of the utility model is to provide a practical lighting device that can provide reflected light friendly to the eyes, reducing the glare and dazzling sensations brought by direct light, making the light softer and more comfortable, and suitable for places that require long-term reading, working, or resting.

[0006] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0007] A practical lighting device includes a number of hollow prisms; a number of reflecting plates are arranged between the prisms, and the reflecting plates correspond to the side edges of the prisms one by one; the width of the reflecting plate is smaller than the width of the side edge of the prism; a support assembly is arranged outside the reflecting plate, and the support assembly is used to suspend the prism; a lighting assembly is arranged in the area surrounded by the reflecting plates.

[0008] The following are the beneficial effects of adopting the above scheme:

[0009] 1. In this scheme, the lighting assembly located in the area surrounded by the reflecting plates emits light. The light undergoes multiple reflections and scatterings between the reflecting plates, and finally propagates into the surrounding space through the gaps between the reflecting plates and the top and bottom areas of the prism. During this process, the light experiences multiple changes in direction and intensity, forming a soft and layered lighting effect.

[0010] Compared with traditional direct lighting technologies, in this solution, through multiple reflections of the reflector, the light is effectively dispersed and softened, reducing the irritation of direct light to the eyes, lowering the glare and dazzling sensations, and providing a more comfortable lighting environment for users.

[0011] 2. In this solution, the light formed through multiple reflections creates rich light and shadow variations in space, enhancing the three-dimensional and hierarchical sense of the space and making the lighting effect more vivid and interesting.

[0012] Furthermore, a suspension plate is provided on the prism located at the top of the reflector.

[0013] Beneficial effect: By providing a suspension plate on the prism, it provides a support point for the support component to suspend the prism, which is beneficial for the support component to stably lift the prism.

[0014] Furthermore, the support component includes a number of support rods; the support rods are arranged circumferentially along the prism, a number of cross bars are provided on the support rods, the cross bars are arranged circumferentially along the prism, and both ends of the cross bars are detachably connected to adjacent support rods; a hanging rod is provided above the prism, and a sling for binding the suspension plate is provided on the hanging rod.

[0015] Beneficial effect: By arranging the support rods circumferentially along the prism and strengthening them with cross bars, a stable support framework is formed. This structural design can ensure that the prism, the reflector and the lighting component thereon remain stable in the suspended state, are not easily shaken or deformed, thus ensuring the overall stability and safety of the lighting device.

[0016] Furthermore, a rotating shaft is provided inside the reflector, and both ends of the rotating shaft are rotatably connected to the prism; a motor is provided inside one of the prisms, and the output shaft of the motor is coaxially and fixedly connected to the rotating shaft.

[0017] Beneficial effect: By driving the rotating shaft with the motor, and then driving the reflector to deflect, the opening and closing size of the gap between the reflectors can be adjusted, so as to realize the illuminance adjustment of the surrounding space.

[0018] Furthermore, a detection module for detecting the human body position and a controller for driving the motor are also provided inside the prism; the controller is electrically connected to the detection module, the motor and the lighting component respectively.

[0019] Beneficial effect: When the detection module detects that a human body approaches, the controller will control the motor to operate, and then drive the reflector to deflect, so as to adjust the illuminance according to the real-time position of the human body.

[0020] Furthermore, the lighting component includes a base body, a hanging rope and a number of LED lights; the LED lights are laid on the surface of the base body; one end of the hanging rope is fixedly connected to the suspension plate, and the other end of the hanging rope is fixedly connected to the base body.

[0021] Beneficial effects: The LED lights can be easily combined with various intelligent control systems to achieve functions such as dimming, color temperature adjustment, and scene mode switching. At the same time, by laying the LED lights on the surface of the base body, it can ensure more uniform light emission, avoiding problems such as light concentration or dark areas that may occur in traditional lighting methods. This design makes the light distribution in the lighting area more balanced, improving visual comfort and lighting quality.

[0022] The design of the hanging rope cleverly connects the hanging plate and the base body, forming a stable structure. When external factors (such as wind force, vibration, etc.) cause the whole prism to shake, the base body can generate an opposite movement trend due to the restraint of the hanging rope, thus offsetting the impact of the shake to a certain extent. This design improves the stability of the entire light-emitting component, extends the service life, and reduces potential safety hazards caused by shaking.

[0023] Furthermore, a limiting rope is provided at the bottom of the base body, and the other end of the limiting rope is fixedly connected to a prism located below the base body.

[0024] Beneficial effects: By adding a limiting rope below the base body, it is possible to prevent the base body from having too large an amplitude during movement, thereby avoiding hitting adjacent reflector plates and reducing the resulting noise and vibration.

[0025] Furthermore, the base body is in the shape of a prism, and the LED lights are respectively arranged on the side surfaces of the base body; the LED lights are all electrically connected to the controller.

[0026] Beneficial effects: When the detection module detects that a person is approaching and stays, the controller also controls the LED lights on other side surfaces of the base body to turn off or reduce the power, and keeps the LED lights on the side surface of the base body in the same direction as the person running normally. The design of the prismatic base body enables the LED lights to be evenly distributed on each side surface, thereby achieving full-range lighting coverage in a limited space. Combined with the intelligent control of the controller, turning off or reducing the power of the LED lights on other non-essential side surfaces can significantly reduce the energy consumption of the lighting equipment, make more effective use of space resources, and meet the lighting needs in different scenarios.

[0027] Furthermore, a mortise and tenon connection is adopted between the support rod and the cross bar.

[0028] Beneficial effects: The mortise and tenon connection relies on the concave and convex parts between wooden components to bite each other, without the need for additional metal welding or bolt fixation. It reduces the risk of structural instability caused by welding or bolt loosening.

[0029] Furthermore, the prism is a triangular prism.

[0030] Beneficial effects: By setting the prism as a triangular prism, it can use less materials while having stability. Description of the Drawings

[0039] The following is a further detailed description through specific embodiments:

[0040] The embodiment is basically as shown in the attached Figures 1 - 4 figure:

[0041] A practical lighting device includes several hollow prisms 2. In this embodiment, two prisms 2 are used, and the prism 2 is specifically a triangular prism 2; attached Figure 1 As shown, a hanging plate 6 is embedded on the prism 2 at the top; several reflecting plates 1 are arranged between the prisms 2, and the reflecting plates 1 correspond to the side edges of the prisms 2 one by one, that is, three reflecting plates 1 are provided; the width of the reflecting plate 1 is smaller than the width of the side edge of the prism 2, so as to ensure that light can escape from the gaps between the reflecting plates 1; a rotating shaft 101 is arranged on the central axis along the length direction inside the reflecting plate, and both ends of the rotating shaft 101 are respectively embedded in the prism 2 and rotatably connected to the prism 2; a motor 102 is arranged in one of the prisms 2, and the output shaft of the motor 102 is coaxially welded and fixed to the rotating shaft 101.

[0042] A support assembly is arranged outside the reflecting plate 1, and the support assembly is used to hang the prism 2; a lighting assembly is arranged in the area surrounded by the reflecting plates 1.

[0043] Specifically, the support assembly includes several support rods 3. As attached Figure 1 As shown, four support rods 3 are arranged in this example; the support rods 3 are arranged along the circumferential direction of the prism 2, and several cross bars 4 are arranged on the support rods 3. The cross bars 4 are arranged along the circumferential direction of the prism 2, and both ends of the cross bars 4 are respectively tenoned and mortised with adjacent support rods 3. Specifically, in this embodiment, mortise grooves are opened on the support rods 3 or cross bars 4, and they are engaged with the protruding parts on the support rods 3 or cross bars 4 to achieve tenon and mortise connection; a hanging rod 401 is arranged above the prism 2. Specifically, the hanging rod 401 is embedded in the mortise groove on the cross bar 4, and a sling 5 for binding the hanging plate 6 is hung on the hanging rod 401.

[0044] Specifically, the lighting assembly includes a base body 8, a hanging rope 7, and several LED lights 801; the shape of the base body 8 is a triangular prism 2, and the LED lights 801 are respectively bonded and fixed to the side surface of the base body 8. Both ends of the hanging rope 7 are respectively tied to the base body 8 and the hanging plate 6.

[0045] A detection module for detecting the human body position and a controller for driving the motor 102 are also arranged in the prism 2; the controller is electrically connected to the detection module, the motor 102, and the LED lights 801 respectively. In this embodiment, the detection module is several thermosensitive sensors arranged circumferentially in the prism 2. As a heat-emitting body, the human body will generate thermal radiation in the air. When a person passes by, the temperature will change significantly, and the thermosensitive sensors can sense these temperature changes. The specific model is the MLX90614 infrared temperature sensor.

[0046] A limiting rope is welded and fixed to the bottom of the base body 8, and the other end of the limiting rope is tied to the prism 2 located below the base body 8.

[0047] The specific implementation process is as follows:

[0048] In this embodiment, the reflector is specifically made of brushed metal. This material not only has the characteristics of being strong and durable, capable of resisting wear and deformation during daily use, but also shows an elegant and delicate texture due to its unique surface treatment process - the brushing process. The brushing treatment makes the metal surface form delicate and uniform textures, which can produce rich light and shadow changes under the illumination of light, enhancing the visual hierarchy.

[0049] When the LED lamp 801 is powered on and emits light, these lights first directly irradiate onto the reflector. The reflector made of brushed metal reflects the light efficiently. A part of the light is directly reflected out along a specific angle to illuminate the surrounding environment; while another part of the light undergoes multiple diffuse reflections on the surface of the reflector, forming a soft and uniform lighting effect. This diffuse reflection not only reduces glare but also enables the light to cover a wider angle, providing multi-angle light supplementation for the space.

[0050] When there is no object (person) near the prism 2, the LED lamp 801 operates at the basic power, that is, only maintaining the most basic lighting requirements.

[0051] When someone approaches the prism 2, the detection module built into the prism 2 will obtain the heat change. The controller judges the distance of the human body based on the heat change. The higher the heat, the closer the distance. By comparing the heat collected by each detection module, the specific orientation of the human body is judged (thermal sensors at different positions will receive infrared radiation signals of different intensities. By analyzing the intensity differences, change trends, and time delays of these signals, the relative position or orientation of the human body in the monitoring area can be roughly inferred). When the human body approaches, the controller controls the motor 102 at the corresponding angle to drive the rotating shaft 101, and the rotating shaft 101 drives the reflector to deflect, increasing the gap between the reflectors in the same direction as the human body, so as to improve the illumination intensity in the corresponding orientation.

[0052] When the staying time of the human body near the prism exceeds the preset time, the controller will control the LED lamps 801 in other orientations on the base 8 to operate at a reduced power (i.e., the basic power when there is no one around) or directly stop operating, and only keep the LED lamps 801 on the base 8 in the same direction as the human body operating normally.

[0053] The above are only embodiments of the present utility model. Specific structures and / or common knowledge such as characteristics well known in the art are not described in detail here. It should be noted that for those skilled in the art, without departing from the structure of the present utility model, several deformations and improvements can still be made, which should also be regarded as the protection scope of the present utility model, and these will not affect the implementation effect of the present utility model and the practicability of the patent. The protection scope required by this application should be subject to the content of its claims, and the specific implementation manners described in the specification can be used to explain the content of the claims.
