Description

Technical Field

[0001] This utility model relates to lighting fixtures, specifically to a lighting fixture for displaying the state of point-like objects. Background Technology

[0002] Existing lighting fixtures include ambient lights, camping lights, and patio lights. Traditional lighting fixtures typically produce ordinary flickering effects, have simple designs, and are bulky in structure. For example, existing animal lights usually only use light projection to simulate the shape of animals (such as fireflies), and use driving circuits to drive the movement of the light to simulate the movement of animals.

[0003] Traditional dynamic simulation lights of this type cannot truly simulate the natural and random dynamic trajectories of animals such as fireflies, nor can they display the natural flying and flashing effects of fireflies, thus failing to achieve a visually pleasing display effect.

[0004] In addition, existing lamps of this type have the disadvantages of being dazzling and having significant light loss. Utility Model Content

[0005] To address the technical problems described above, this invention aims to provide a lamp for displaying the states of point objects.

[0010] In one embodiment, the lamp unit controls the size of the presented dot-like object based on at least one of the size of a single lamp bead, the scattering degree of the light emitted by the single lamp bead by the inner lamp cover, and the distance between the inner lamp cover and the lamp bead.

[0011] In one embodiment, the control logic is set based on the on / off state, on / off time and / or light intensity of the same LED or two adjacent LEDs on a curved trajectory to simulate the flickering state of a point object such as a firefly.

[0021] It should be noted that all the accompanying drawings in this application are schematic drawings, used only to illustrate the principle of this utility model, and are not necessarily drawn to actual scale. Detailed Implementation

[0022] The present invention will now be described with reference to the accompanying drawings.

[0023] In this application, it should be noted that the directional terms "up," "down," "inner," and "outer" used in this application are all referenced in the appendix. Figure 1 The lighting fixtures shown are for the purpose of facilitating and simplifying the description of this utility model, and should not be construed as constituting any limitation on this utility model.

[0024] This invention provides a lamp for displaying the state of an object. This lamp is particularly suitable for simulating various active states of point objects, such as movement and stillness (i.e., a non-moving state, but still capable of dynamic changes such as brightness variations), thereby showcasing the different states of point objects. In this document, a point object refers to an object with a certain (usually small) size, which typically has a fixed or substantially fixed shape.

[0025] In the context of this invention, a point-like object can be an organism, particularly a single organism within a group of organisms. An organism may be, for example, a firefly, whose state may include flying, stationary, flashing, etc. An organism may also be a paramecium, etc. A point-like object can also be a microscopic particle, such as a tiny particle undergoing Brownian motion in a liquid or gas.

[0026] In the context of this invention, the lamps according to this invention can display different states of point objects, especially the continuous movement of point objects.

[0027] In the context of this utility model, the lamps according to this utility model are suitable for different application scenarios. They can be designed as ambient lights, courtyard lights, camping lights for outdoor sports, and can also be used for indoor lighting, decoration, or for enjoyment.

[0028] For ease of description, this invention will be described below using a lamp for displaying the behavior of fireflies as an example. This lamp can present users with a similar movement pattern and behavior to fireflies. In the following text, this lamp according to this invention will be simply referred to as a firefly lamp. However, it is readily understood that the firefly lamp is merely a specific example of this invention and does not constitute any limitation on the invention.

[0029] Figure 1 and Figure 2 The structure of the firefly lamp 100 according to the present invention is schematically shown, wherein, Figure 1 This is a sectional view. Figure 2 This is an exploded perspective view. For example... Figure 1 and Figure 2 As shown, the firefly lamp 100 includes a base 12, a lamp body unit 50 mounted on the base 12, and a control unit (not shown). The firefly lamp 100 also includes an optional outer lamp cover 3, which is also mounted on the base 12 and located outside the lamp body unit 50.

[0030] According to this utility model, the lamp body unit 50 includes an inner lampshade 5 mounted on a base 12, and a flexible circuit board (FPC) body 6 disposed within the inner lampshade 5. In the illustrated embodiment, both the inner lampshade 5 and the FPC body 6 are constructed in a cylindrical shape to facilitate manufacturing and assembly, and to enhance aesthetics. However, it is understood that the inner lampshade 5 and the FPC body 6 can also be constructed in other shapes, all of which fall within the scope of this utility model.

[0031] Multiple LED beads 61 are arranged on the outer surface of the FPC body 6. These LED beads 61 can be arranged in one or more curved trajectories. Figure 3 The diagram schematically shows the FPC body 6 in its unfolded state, and the LED beads 61 arranged thereon. Figure 3 As shown, the LEDs 61 are arranged on the outer surface of the FPC body 6 along four different curved trajectories (hereinafter also referred to as "simulated flight trajectories"). These curved trajectories may be completely spaced apart or intersect at certain points. The LEDs 61 may be LEDs, such as surface-mount LEDs.

[0032] According to this invention, the control unit is signal-connected to the FPC body 6. Therefore, the control unit can control the LED beads 61, causing each LED bead 61 to light up or turn off according to the set control logic. Thus, the firefly lamp 100 can present various different states of a dot-shaped object (i.e., a firefly) to simulate the states of a firefly flying, stationary, and flashing.

[0033] Specifically, the LED beads 61 are arranged according to the flight path of a firefly to form multiple different simulated flight paths, such as... Figure 3 As shown. In one embodiment, during flight, the control unit controls the on / off state, on / off sequence, and / or light intensity of different LED beads 61, so that the LED beads 61 can be energized and illuminated sequentially according to the corresponding simulated flight trajectory, thereby simulating the on / off and flight state of one or more fireflies on each simulated flight trajectory. When simulating the flight state of a firefly, 1-2 LED beads can be set to be lit simultaneously to simulate the effect of a firefly. By adjusting the on / off time and light intensity of the LED beads 61, the on / off and smooth flight effect of the firefly can be presented. Assume that each LED bead on a simulated flight trajectory is numbered 1, 2, ..., n sequentially from the starting point to the ending point. If one LED bead is lit at a time, then lighting one LED bead 61 sequentially from 1 to n and then turning it off can simulate the effect of a firefly flying along the simulated flight trajectory. If two LEDs are lit, the effect of a firefly flying along a simulated flight path can be simulated by gradually dimming the first LED and gradually brightening the second LED until the first LED goes out, then gradually dimming the second LED and gradually brightening the third LED, and so on.

[0034] Figure 4 The diagram shows the control logic of a single LED in flight mode. In flight mode, the single LED exhibits four flashing patterns: J-shaped flashing, flashing flight, gradual brightening followed by rapid dimming, and natural drifting (female). Figure 4 The thick lines in the graph represent the firefly's flight phase with its lights on, and the corresponding brightness-time graph shows the pattern of how the brightness of the firefly represented by each thick line changes over time.

[0035] In another implementation, in a stationary state, the control unit controls the on / off state, on / off time, and / or light intensity of the same LED bead 61 or several adjacent LED beads 61 (e.g., two) on the same simulated flight path, thereby simulating the blinking of a firefly in place. When simulating a stationary firefly, one or two LED beads can be lit simultaneously to simulate the effect of a single firefly. If one LED bead is lit, its on / off time and light intensity can be adjusted to achieve the effect of a firefly blinking in place. If two LED beads are lit, the on / off time and light intensity of two adjacent LED beads on the same simulated flight path can be adjusted to achieve the effect of a firefly blinking in place.

[0036] Figure 5 The diagram shows the control logic of a single LED in a stationary state. In this state, the single LED also exhibits four flashing modes: gradual brightening followed by a breathing effect, stationary flashing, gradual brightening followed by a rapid dimming, and flashing followed by gradual brightening. The corresponding brightness-time graph in the diagram illustrates the change in the firefly's brightness over time.

[0037] In one embodiment, multiple LEDs are controlled to illuminate on each of the multiple simulated flight paths to simulate several (e.g., 1-10) fireflies, and some of the fireflies are randomly controlled to be in flight while others are stationary and flashing. This achieves the effect of simulating fireflies and their various states from various angles when observing the firefly lamp.

[0038] Back to Figure 1 and 2 In one embodiment, the outer lampshade 3 is constructed in a cylindrical shape and made of a transparent material to allow the light emitted by the lamp body unit 50 to be observed from the outside. The lower end of the outer lampshade 3 is fixedly mounted on the base 12. The upper end of the outer lampshade 3 has an opening through which a top cover 1 is detachably mounted.

[0039] The FPC body 6 is fixedly mounted on the base 12 by an internal support frame 7. The internal support frame 7 is preferably constructed in a cylindrical shape, with its lower end fixed to the base 12. The FPC body 6 is fitted around the internal support frame 7. Thus, the outer lampshade 3, the inner lampshade 5, the FPC body 6, and the internal support frame 7 are all preferably made in a cylindrical shape to facilitate manufacturing and assembly.

[0040] According to this invention, the inner lampshade 5 is configured such that the user can observe the light emitted by the LED beads 61 on the FPC body 6 through it, but cannot observe other non-light-emitting components provided in the inner lampshade 5, such as the internal support frame 7. In other words, the inner lampshade 5 is "transparent but not transparent".

[0041] The inner lampshade 5 can be made of resin materials, such as polyethylene (PE), polypropylene (PP), polystyrene (PS), polytetrafluoroethylene (PTFE), polyvinyl chloride (PVC), phenolic resin (PF), polycarbonate (PC), polyurethane (PU), polyamide (PA), and other transparent resin materials. Preferably, the inner lampshade 5 can be made of PC, PVC, PS, PMMA, etc.

[0042] In one embodiment, a light diffusing agent may be added to the inner lampshade 5. The light diffusing agent enhances the scattering and transmission of light passing through the inner lampshade 5, which is made of transparent resin, thus softening the light emitted through the resin. Simultaneously, the inner lampshade 5 is thus formed to be "transparent but not transparent." The light diffusing agent may be, for example, an inorganic light diffusing agent such as titanium dioxide, barium sulfate, calcium carbonate, or silicon dioxide, or an organic light diffusing agent such as a styrene-type or acrylic resin-type agent. Resin-type light diffusing agents are transparent or translucent particles, allowing most of the light to pass through, and their refractive index differs little from that of the substrate. After multiple refractions, the light passing through the substrate becomes bright and soft, with minimal impact on the material's transmittance. In some specific embodiments, the light transmittance of the added light diffusing agent is about 75% or more, preferably about 85% or more, and more preferably about 90% or more. In other specific embodiments, the haze of the added light diffusing agent is about 50-92%, for example, about 75-90%. In some specific embodiments, the light diffusing agent has a weight percentage of about 0.1%-10% in the substrate, preferably about 0.2%-5%. The thickness of the inner lampshade 5 is generally about 0.1-20 mm, for example about 0.5-5 mm.

[0043] In one embodiment, the inner lampshade 5 is made of polycarbonate (PC) material, wherein titanium dioxide is added as a light diffusing agent, and the weight percentage of the light diffusing agent is about 0.3%-5%.

[0044] In another embodiment, the inner lampshade 5 is configured to allow light to propagate primarily from the inside out. Thus, the user can observe the light emitted by the LEDs 61 on the FPC body 6 through the inner lampshade 5, but cannot observe other non-light-emitting components located inside the inner lampshade 5. In this way, the inner lampshade 5 is also "transparent but not transparent." In one embodiment, the outer surface of the inner lampshade 5 can be treated with light-reflecting properties, for example, by adding a material to the inner lampshade 5 to increase the reflection of light illuminating from the outside in, or by providing a reflective film on the inner lampshade 5. In a specific embodiment, a reflective film, such as a metal (nickel, chromium, tin, gold, silver, etc.) or alloy film, is coated on the outer surface of the inner lampshade 5. Utilizing the light reflection and absorption properties of the metal coating, light incident from the outside into the inner lampshade is reflected and absorbed. Thus, the user cannot observe other non-light-emitting components located inside the inner lampshade 5, but can still observe the light emitted by the LEDs 61 on the FPC body 6 through the inner lampshade 5. In a specific example, the outer surface of the inner lampshade 5 is treated by a vacuum plating process to form an indium tin alloy plating layer, the thickness of which is, for example, about 0.05-0.1 μm.

[0045] For the firefly lamp 100 of this invention, the light emitted by the LED beads 61 on the FPC body 6 forms a light spot on the inner lampshade 5, which is used to simulate a firefly. Generally, it is desirable for the light spot observed by the user to have a specified size, for example, similar to the simulated dot-like object (i.e., a firefly). According to this invention, the size of the presented dot-like object can be controlled by one or more of the following settings: the size of a single LED bead 61, the scattering degree of the light emitted by a single LED bead 61 by the inner lampshade 5, and the distance between the inner lampshade 5 and the FPC body 6. The scattering degree of the light emitted by a single LED bead 61 by the inner lampshade refers to the degree to which some light deviates from the incident direction and is scattered due to multiple refractions within the material when light enters and passes through the inner lampshade.

[0046] The inventor discovered that, due to scattering, the light spot formed on the inner lampshade 5 by a single LED 61 can be divided into a central part and a peripheral part according to the light intensity. The central part of the light spot mainly consists of the light directly transmitted from the LED 61 through the inner lampshade 5, and also includes some light scattered at a small angle (within approximately 45 degrees, for example, within 20 degrees). The peripheral part of the light spot mainly consists of the light scattered after the LED 61 passes through the inner lampshade 5. The light intensity of the central and peripheral parts of the light spot is different, with the central part being significantly stronger than the peripheral part, with an intensity difference between 2 and 50 times. The human pupil's size changes with the intensity of ambient light; the stronger the ambient light, the smaller the pupil, receiving less light, and the higher the light intensity requirement for observable objects; conversely, the weaker the ambient light, the larger the pupil, receiving more light, and the lower the light intensity requirement for observable objects. The lamp according to this invention needs to be used under different ambient light conditions, while simultaneously maintaining the size of the light spot observed by the naked eye within a desired range. The inventors have discovered that under bright ambient light (such as outdoor daytime or indoor lighting), the size of the light spot observed by the naked eye is mainly concentrated in the central part of the spot, with the peripheral part almost completely invisible; while under dimmer ambient light (such as outdoor nighttime or indoor lighting that is off or very weak), the size of the light spot observed by the naked eye includes the peripheral part of the spot. Therefore, the size of the light spot observed varies under different environments, and in particular, the size of the light spot observed under dimmer ambient light may exceed the desired size.

[0047] Therefore, according to this invention, the size of the presented dot-shaped object is controlled by one or more of the following: the size of a single LED bead 61, the scattering degree of the light emitted by the inner lampshade 5 to the single LED bead 61, and the distance between the inner lampshade 5 and the LED bead 61. For example, by adjusting the material of the inner lampshade 5 and the type and proportion of the added light diffusing agent, the scattering degree of the light emitted by the inner lampshade 5 to the single LED bead 61 can be reduced, thereby reducing the area of ​​the peripheral portion of the light spot and achieving the purpose of controlling the size of the light spot. Alternatively, the distance between the inner lampshade 5 and the LED bead 61 can be reduced. For example, in one embodiment of this invention, a surface-mount LED bead with an upper surface luminous area of ​​about 0.5-5mm by about 0.5-5mm (e.g., a 0805 type LED bead of 2mm by 1.25mm) is used. In this embodiment, the distance between the inner lampshade 5 and the LED bead 61 can be about 0.1-5mm, preferably about 0.1-2mm. Alternatively, by adjusting the material of the inner lampshade 5 and the type and proportion of the added light diffusing agent, the light intensity difference between the central and peripheral parts of the light spot can be reduced, thereby adjusting the size of the central and peripheral parts of the light spot so that both are within an acceptable predetermined range.

[0048] In a preferred embodiment, LED chips with a relatively small emission angle can be used. For example, when using LED chips, focused LED chips are selected. Focused LED chips have high light directivity, with a half-value angle of approximately 5° to 20°, or less. Focused LED chips include LED chips with cup-shaped bracket packages (e.g., epoxy resin packages) or LED chips with metal reflector cavities, and typically do not contain diffusing agents.

[0049] For the firefly lamp 100 of this invention, the light emitted by the LED beads 61 on the FPC body 6 forms a light spot on the inner lampshade 5, which is used to simulate a firefly. Generally, it is desirable for the light spot observed by the user to have a moving speed and / or moving mode within a specified range, especially a continuous moving mode (i.e., non-jumping movement). The moving speed of the light spot observed by the user should generally conform to the speed of a firefly. The observed moving speed of the firefly is not necessarily the actual flight speed of the firefly, but the moving speed observed at a certain distance, or the moving speed of an object that conforms to the observer's preferred speed (to suit different moods such as relaxed or active). In some embodiments, it is desirable for the moving speed of the light spot observed by the user not to exceed 100 mm / s, preferably not exceeding 50 mm / s, for example, about 5-50 mm / s.

[0050] According to this invention, by appropriately controlling the lighting sequence, frequency, duration, and / or spacing of adjacent LED beads, the movement speed and / or movement mode of the presented point-like object (i.e., firefly) can be controlled. In this invention, the spacing between adjacent LED beads should be as small as possible to avoid the undesirable effect of the object appearing to jump (i.e., discontinuous movement) when the spacing between adjacent LED beads is large. The applicant has found that when the spacing between adjacent LED beads is large, resulting in the phenomenon of the object appearing to jump, this undesirable effect cannot be overcome by increasing the lighting frequency of the LED beads. In one specific embodiment, the distance between adjacent LED beads on the FPC body 6 (center-to-center distance between LED beads) is less than about 5 mm, for example, about 0.5-5 mm, preferably about 1-2.5 mm.

[0051] Back to Figure 1 and 2 The firefly lamp 100 according to this utility model also includes a first lighting unit and a second lighting unit. The first lighting unit is disposed on the top of the inner lamp cover 5, and the second lighting unit is disposed on the base 12 and located between the outer lamp cover 3 and the inner lamp cover 5.

[0052] According to this utility model, the first lighting unit includes a reflector cone 51, a top white lamp 4, and a reflector 2. The reflector cone 51 is located in the central area of ​​the top of the inner lamp cover 5, and has a hollow structure with the upper end larger than the lower end. The top white lamp 4 is located at the bottom of the reflector cone 51, and may be composed of, for example, 1-10 white LED beads. The top white lamp 4 is signal-connected to the control unit, so that the control unit can control the top white lamp 4 to turn on or off. The reflector 2 is located at the top of the outer lamp cover 3, and is opposite to and spaced a certain distance from the top white lamp 4.

[0053] like Figure 6 As shown, the lower surface of the reflector 2 is configured as a reflective surface 21. In this way, the top white light 4, in conjunction with the structure of the reflective cone 51, reflects light onto the reflector 2 and then outwards through the reflective surface 21. The upper surface of the reflector 2 is configured as a plane for fixed connection to the top of the inner lamp cover 3. The reflective surface 21 of the reflector 2 is configured as a spherical surface and is treated with a polished mirror electroplating. Preferably, the reflector 2 is made of PC / ABS with a polished mirror electroplating. This allows the white light emitted by the top white light 4 to be reflected outwards through the reflective surface 21 of the reflector 2, which not only helps prevent glare but also reduces light loss.

[0054] According to this invention, the second lighting unit includes a bottom white lamp 10 and a light diffuser 9. The bottom white lamp 10 includes an FPC element configured in a frustum shape, and lighting beads, such as LED beads, arranged on the FPC element. Preferably, a plurality of (e.g., 8-100) lighting beads are circumferentially evenly arranged on the FPC element. The bottom white lamp 10 is signal-connected to a control unit, allowing the control unit to control the bottom white lamp 10 to be turned on or off. The light diffuser 9 is disposed above the bottom white lamp 10, and preferably is arranged parallel to the frustum portion of the FPC element. Both the FPC element and the light diffuser 9 have through holes for the inner lamp cover 5 to pass through, thereby fitting the bottom white lamp 10 and the light diffuser 9 onto the inner lamp cover 5. Figure 7 As shown, the light emitted by the bottom white lamp 10 can be diffused in all directions through the electroplated layer on the outer surface of the light diffuser 9 and the inner lamp cover 5, thereby enhancing the illumination and significantly reducing light loss.

[0055] In one embodiment, the light-diffusing mask 9 can be made of silicone / PC doped with light-dispersing powder, for example. This achieves a uniform light effect and also provides anti-glare functionality.

[0056] In addition, according to one embodiment of the present invention, the second lighting unit further includes a heat dissipation substrate 11 for effectively dissipating heat from the bottom white lamp 10. The heat dissipation substrate 11 is disposed at the lower end of the bottom white lamp 10 and fixed to the base 12. The aluminum substrate 11 is preferably made of aluminum and is also configured in a frustoconical shape.

[0057] In one embodiment, the base 12 is cylindrical. A control switch 15, connected to a control unit, is provided on the base 12. The control switch 15 is preferably located on the side wall of the base 12. By pressing the control switch 15, the firefly lamp 100 can be switched between an off mode, a top lighting mode, a bottom lighting mode, and a firefly mode. In the off mode, the lamp body unit 50, the first lighting unit, and the second lighting unit are all off. In the top lighting mode, only the first lighting unit is on. In the bottom lighting mode, only the second lighting unit is on. In the firefly mode, only the lamp body unit 50 is on. Furthermore, in both the bottom lighting mode and the top lighting mode, the lighting brightness can be adjusted by rotating the control switch 15.

[0058] The firefly lamp 100 also includes a power supply 8 for supplying power to the lamp body unit 50, the first lighting unit, and the second lighting unit. According to this invention, the power supply 8 is arranged inside the FPC body 6, specifically inside the cylindrical internal support frame 7. The power supply 8 is vertically arranged, with its lower end fixed to the base 12. Thus, the entire firefly lamp 100 has a compact structure.

[0059] In one embodiment, a printed circuit board 13 is provided inside the base 12. The lower end of the power supply 8 passes through the top plate of the base 12 and is fixedly connected to the printed circuit board 13. The base 12 may also be provided with a first interface 16 for charging and a second interface 14 for external charging. Preferably, the first interface 16 is, for example, a Type-C interface, and the second interface is, for example, a Type-A interface. Further, the first interface 16 and the second interface 14 are spaced apart in the longitudinal direction and are both located on the side wall opposite to the control switch 15.

[0060] In one embodiment (not shown), the firefly lamp 100 also includes a gyroscope sensor and an accelerometer sensor. In firefly mode, the flight state of all fireflies can be changed by tapping, picking up, or shaking the firefly lamp 100.

[0061] The firefly lamp 100 of this invention can simulate the flight and flashing effects of fireflies through its lamp body unit 50, and can achieve various flashing patterns by controlling the LED beads in the lamp body unit 50. Therefore, the firefly lamp 100 of this invention can achieve flashing effects in various scenarios, effectively ensuring the realism of the simulated firefly effect. At the same time, the light-transmitting but not transparent inner lamp cover 5 further enhances the aesthetics of the firefly lamp 100. In addition, the firefly lamp 100 of this invention allows for convenient control of the size, movement speed, and movement pattern of the simulated firefly, further improving the realism of the simulated firefly effect. Furthermore, the firefly lamp 100 has a simple structure, small size, is easy to carry, and has a simple control method, making it easy to operate.
