Background Art

[0002] Existing lamps include ambient lights, camping lights, garden lights, etc. Conventional lamps can only display a common light blinking effect, have a simple design, and a bulky structure.

Modes for Carrying Out the Invention

[0026] Hereinafter, the present invention will be described with reference to the drawings.

[0027] In this specification, terms indicating directions such as "up", "down", "inside", and "outside" all refer to the lamp shown in FIG. 1, and these terms are only used for facilitating and simplifying the description of the present invention and are not intended to limit the present invention.

[0028] The present invention provides a lamp for displaying the state of an object. This lamp is particularly suitable for simulating various active states of a point-like object, such as moving states and stationary states (i.e., non-moving states, but with dynamics such as changes in brightness), and displays various different states of a point-like object. In this specification, a point-like object refers to an object having a certain (usually small) size and generally having a fixed or basically fixed form.

[0029] In this invention, a point-like object refers to a living organism, particularly a single organism or a single organism within a group of organisms. The organism may be, for example, a firefly, and its state may include flying, stationary, flashing, etc. The organism may also be a paramecium or the like. The point-like object may also be a microparticle (for example, a tiny particle undergoing Brownian motion in a liquid or gas).

[0030] In the present invention, the lamp according to the present invention can display different states of a point-like object (in particular, the continuous movement of a point-like object).

[0031] In this invention, the lamp according to the present invention is suitable for various application scenarios and can be designed as an ambient lamp, garden lamp, or camping lamp for outdoor sports, and can also be used for indoor lighting, decoration, or entertainment.

[0032] For the sake of explanation, the present invention will be described below using a lamp that displays the behavior of fireflies as an example. This lamp can display to the user the movement and behavior of fireflies. Hereinafter, such a lamp of the present invention will simply be referred to as a firefly lamp. However, it will be easily understood that the firefly lamp is merely one specific example of the present invention and does not limit the present invention.

[0033] Figures 1 and 2 schematically show the structure of the firefly lamp 100 according to the present invention, with Figure 1 being a cross-sectional view and Figure 2 being an exploded perspective view. As shown in Figures 1 and 2, the firefly lamp 100 comprises a base 12, a lamp body unit 50 mounted on the base 12, and a control unit (not shown). The firefly lamp 100 may optionally further include an outer lampshade 3 mounted on the base 12 and located outside the lamp body unit 50.

[0034] According to the present invention, the lamp body unit 50 comprises an inner lampshade 5 mounted on a base 12 and a flexible printed 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 formed in a cylindrical shape to facilitate manufacturing and assembly and to improve aesthetics. However, the inner lampshade 5 and the FPC body 6 can also be configured in other shapes, and it goes without saying that these shapes are also within the scope of the present invention.

[0035] Multiple lamp beads 61 are arranged on the outer surface of the FPC body 6. These lamp beads 61 can be arranged along one or more curved trajectories. Figure 3 schematically shows the FPC body 6 in an unfolded state and the lamp beads 61 arranged on it. As shown in Figure 3, the lamp beads 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 separated or may intersect at some point. LED lamp beads (e.g., surface-mount LED lamp beads) can be used for the lamp beads 61.

[0036] According to the present invention, the control unit is communicatively connected to the FPC body 6. Therefore, the control unit can control the lamp beads 61 and turn each lamp bead 61 on or off according to the set control logic. As a result, the firefly lamp 100 can display various different states of a point-like object (i.e., a firefly), and can simulate the flying, stationary, and flashing states of a firefly.

[0037] Specifically, as shown in Figure 3, the lamp beads 61 are arranged along the firefly's flight path to form multiple different simulated flight paths. In one embodiment, during flight, the control unit controls the on / off state, on / off sequence, and / or light intensity of different lamp beads 61, thereby sequentially energizing and illuminating the lamp beads 61 along the corresponding simulated flight path, and simulating the flashing and flight state of one or more fireflies along each simulated flight path. When simulating the flight state of a firefly, the effect of one firefly can be simulated by lighting up one or two lamp beads simultaneously. By adjusting the on / off timing and light intensity of the lamp beads 61, the flashing and smooth flight effect of a firefly can be demonstrated. Each lamp bead on a simulated flight path is numbered 1, 2, ..., n from the starting point to the ending point. When using a method that lights up one lamp bead, the effect of a firefly flying along the simulated flight path can be simulated by sequentially lighting up one lamp bead 61 from 1 to n and then turning it off. When using a method that lights up two lamp beads, the effect of a firefly flying along the simulated flight path can be simulated by gradually dimming the first lamp bead and gradually brightening the second lamp bead, and once the first lamp bead is turned off, gradually dimming the second lamp bead and gradually brightening the third lamp bead, and repeating this process.

[0038] Figure 4 shows the control logic principle diagram for a single lamp bead in flight. In flight, a single lamp bead exhibits four different flashing patterns: J-shaped flashing, flashing flight, gradual brightness followed by rapid dimmer, and natural floating (female). The thick lines in Figure 4 represent the stages of firefly luminescence flight, and the corresponding brightness-time graphs show the pattern of how the brightness of the firefly represented by each thick line changes over time.

[0039] In another embodiment, in a stationary state, the control unit controls the on / off state, on / off time, and / or light intensity of the same lamp bead 61 or multiple (e.g., two) adjacent lamp beads 61 on the same simulated flight path to simulate the flashing of a firefly staying in place. When simulating a stationary firefly, the effect of one firefly can be simulated by lighting one or two lamp beads simultaneously. When using a configuration where one lamp bead is lit, the flashing effect of a single firefly staying in place can be achieved by adjusting the on / off time and light intensity of the lamp bead. When using a configuration where two lamp beads are lit, the flashing effect of a single firefly staying in place can be achieved by adjusting the on / off time and light intensity of two adjacent lamp beads on the same simulated flight path.

[0040] Figure 5 shows the control logic principle diagram for a single lamp bead in a stationary state. Even in a stationary state, a single lamp bead includes four flashing patterns: gradually brightening and then retracting its tail fins while breathing; flashing while stationary; gradually brightening and then rapidly dimming; and flashing while gradually brightening. The corresponding brightness-time graphs in the figure show the pattern of how the firefly's brightness changes over time.

[0041] In one embodiment, multiple fireflies (for example, 1 to 10) are simulated by controlling the lighting of multiple lamp beads corresponding to each of the multiple simulated flight paths. The fireflies are randomly controlled so that some are in flight mode and some remain stationary while flashing. This provides a simulated effect in which fireflies and various states can be observed from any angle.

[0042] Returning to Figures 1 and 2, in one embodiment, the outer lampshade 3 is cylindrical and made of a transparent material, allowing the light emitted from the lamp body unit 50 to be observed from the outside. The lower end of the outer lampshade 3 is fixedly attached to the base 12. An opening is provided at the upper end of the outer lampshade 3, and the top shade 1 is detachably attached to this opening.

[0043] The FPC body 6 is fixedly attached to the base 12 via an internal support frame 7. The internal support frame 7 is preferably cylindrical in 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, inner lampshade 5, FPC body 6, and internal support frame 7 are all preferably manufactured in a cylindrical shape to facilitate manufacturing and assembly.

[0044] According to the present invention, the inner lampshade 5 is configured so that the user can observe the light emitted from the lamp beads 61 on the FPC body 6 through the inner lampshade 5, but other non-emitting components located inside the inner lampshade 5, such as the internal support frame 7, cannot be observed. In other words, the inner lampshade 5 is "light-transmitting but opaque".

[0045] The inner lampshade 5 can be manufactured from a resin material, such as a transparent resin material such as polyethylene (PE), polypropylene (PP), polystyrene (PS), polytetrafluoroethylene (PTFE), polyvinyl chloride (PVC), phenolic resin (PF), polycarbonate (PC), polyurethane (PU), or polyamide (PA). Preferably, the inner lampshade 5 can be manufactured from PC, PVC, PS, PMMA, etc.

[0046] In one embodiment, a light diffuser can be added to the inner lampshade 5. The light diffuser increases the scattering and transmittance of light passing through the transparent resin inner lampshade 5, and softens the light emitted through the resin. This forms the inner lampshade 5 to be "light-transmitting but opaque". The light diffuser may be an inorganic light diffuser such as titanium dioxide, barium sulfate, calcium carbonate, or silicon dioxide, or an organic light diffuser such as a styrene-based or acrylic resin-based one. Resin-based light diffusers are transparent or translucent particles that transmit most light, and their refractive index is almost the same as that of the substrate. As the light undergoes multiple refractions, the light passing through the substrate becomes brighter and softer, with little effect on the transmittance of the material. In some specific embodiments, the transmittance of the added light diffuser is about 75% or more, preferably about 85% or more, and more preferably about 90% or more. In some other specific embodiments, the haze of the added light diffuser is about 50-92%, for example, about 75-90%. In some specific embodiments, the weight ratio of the light diffusing agent in the substrate is approximately 0.1% to 10%, preferably approximately 0.2% to 5%. The thickness of the inner lampshade 5 is typically approximately 0.1 to 20 mm, for example, approximately 0.5 to 5 mm.

[0047] In one embodiment, the inner lampshade 5 is manufactured from polycarbonate (PC) material, to which titanium dioxide is added as a light diffuser, with the weight ratio of the light diffuser being approximately 0.3% to 5%.

[0048] In another embodiment, the inner lampshade 5 is configured such that light propagates only from the inside to the outside, allowing the user to observe the light emitted from the lamp beads 61 on the FPC body 6 through the inner lampshade 5, but not other non-emitting components located inside the inner lampshade 5. In this case as well, the inner lampshade 5 is "light-transmitting but opaque". In one embodiment, the outer surface of the inner lampshade 5 can be treated to reflect light, for example, by adding a material to the inner lampshade 5 that enhances the reflection of light whose irradiation direction is from the outside to the inside of the lampshade, or by providing a reflective film on the inner lampshade 5. In a specific embodiment, the outer surface of the inner lampshade 5 is plated with a reflective film, for example, a metal (nickel, chromium, tin, gold, silver, etc.) or alloy film. The light-reflecting and absorbing properties of the metal plating film allow it to reflect and absorb light incident from the outside into the inside of the inner lampshade. As a result, the user cannot observe other non-emitting components located inside the inner lampshade 5, but can observe the light emitted from the lamp beads 61 on the FPC body 6 through the inner lampshade 5. As a specific example, an indium-tin alloy plating layer is formed on the outer surface of the inner lampshade 5 by vacuum plating, and the thickness of the plating layer is, for example, about 0.05 to 0.1 μm.

[0049] In the firefly lamp 100 of the present invention, light emitted from lamp beads 61 on the FPC body 6 forms a light spot on the inner lampshade 5, and this light spot is used to simulate a firefly. Generally, it is desirable that the light spot observed by the user has a predetermined size, for example, that is about the same as the simulated point-like object (i.e., a firefly). According to the present invention, the size of the displayed point-like object can be controlled by setting one or more of the following: the size of the individual lamp beads 61, the degree of scattering by the inner lampshade 5 for the light emitted from the individual lamp beads 61, and the distance between the inner lampshade 5 and the FPC body 6. Here, the degree of scattering by the inner lampshade for the light emitted from the individual lamp beads 61 refers to the extent to which a portion of the light is scattered away from the direction of incidence due to multiple refraction within the material as the light enters and passes through the inner lampshade.

[0050] The inventors discovered that, due to scattering, the light spots formed on the inner lampshade 5 by the light emitted from individual lamp beads 61 are divided into a central portion and a peripheral portion based on light intensity. The central portion of the light spot mainly consists of light that has directly passed from the lamp beads 61 to the inner lampshade 5, and also includes light scattered at small angles (within approximately 45 degrees, e.g., within 20 degrees). The peripheral portion of the light spot mainly consists of light that has passed from the lamp beads 61 to the inner lampshade 5 and then scattered. The light intensity of the central and peripheral portions of the light spot differs, with the light intensity of the central portion being 2 to 50 times greater than that of the peripheral portion. A person's pupil changes in response to ambient light intensity; the stronger the ambient light, the smaller the pupil becomes, the less light the pupil receives, and the greater the requirement for light intensity of objects observable to the naked eye. Conversely, the weaker the ambient light, the larger the pupil becomes, the more light the pupil receives, and the lower the requirement for light intensity of objects observable to the naked eye. The lamp according to the present invention needs to be used under various ambient light conditions, and at the same time, it is desirable that the size of the light spot observed with the naked eye be maintained within a desired range. The inventors have found that under relatively bright ambient light (e.g., outdoors during the day or indoors with the lights on), the size of the light spot observed with the naked eye mainly consists of the central part of the light spot, with the peripheral part almost completely invisible, while under relatively dim ambient light (e.g., outdoors at night, or indoors with the lights off or very dim lighting), the size of the light spot observed with the naked eye includes the peripheral part of the light spot. Therefore, the size of the observed light spot varies depending on the environment, and in particular, under relatively dim ambient light, the size of the observed light spot may exceed the desired size of the light spot.

[0051] Therefore, according to the present invention, the size of the point-like object on display is controlled by one or more of the following: the size of the individual lamp beads 61, the degree of scattering by the inner lampshade 5 to the light emitted from the individual lamp beads 61, and the distance between the inner lampshade 5 and the lamp beads 61. For example, by adjusting the material of the inner lampshade 5, the type and proportion of the added light diffuser, the degree of scattering by the inner lampshade 5 to the light emitted from the individual lamp beads 61 can be reduced, thereby reducing the area of ​​the peripheral portion of the light point and achieving the objective of controlling the size of the light point. Alternatively, the distance between the inner lampshade 5 and the lamp beads 61 can also be reduced. For example, in one embodiment of the present invention, surface-mount LED lamp beads (e.g., 0805 type LED lamp beads of 2 mm × 1.25 mm) with a top surface light-emitting area of ​​about 0.5 to 5 mm × about 0.5 to 5 mm are used. In this embodiment, the distance between the inner lampshade 5 and the lamp beads 61 may be about 0.1 to 5 mm, preferably about 0.1 to 2 mm. Alternatively, by adjusting the material of the inner lampshade 5 and the type and proportion of the added light diffusing agent, the difference in light intensity between the central and peripheral parts of the light spot can be reduced, and the size of both the central and peripheral parts of the light spot can be adjusted to fall within an acceptable predetermined range.

[0052] In preferred embodiments, lamp beads with a relatively small emission angle can be used. For example, when using LED lamp beads, condensing LED lamp beads are selected. Concentrating LED lamp beads have relatively high optical directivity, with a half-angle of approximately 5° to 20° or less. Concentrating LED lamp beads include LED lamp beads sealed in a cup-shaped bracket (e.g., epoxy resin sealed) or LED lamp beads sealed in a metal reflective cavity (generally without added scattering agents).

[0053] In the firefly lamp 100 of the present invention, light emitted from the lamp beads 61 on the FPC body 6 forms a light spot on the inner lampshade 5, and this light spot is used to simulate a firefly. Generally, it is desirable that the light spot observed by the user has a movement speed and / or movement pattern within a predetermined range, in particular a continuous movement pattern (i.e., non-jumping movement). The movement speed of the light spot observed by the user should generally correspond to the speed of a firefly. The observed firefly movement speed does not necessarily have to be the actual flight speed of a firefly, but rather the movement speed observed at a certain distance, or the movement speed of an object that suits the observer's preference (for example, suitable for different moods such as relaxed or active). In some embodiments, it is desirable that the movement speed of the light spot observed by the user does not exceed 100 mm / second, more preferably does not exceed 50 mm / second, and for example, is about 5 to 50 mm / second.

[0054] According to the present invention, the movement speed and / or movement pattern of a point-like object (i.e., a firefly) to be displayed can be controlled by appropriately controlling the lighting order, lighting frequency, lighting duration, and / or the distance between adjacent lamp beads. In the present invention, the distance between adjacent lamp beads must be as narrow as possible in order to avoid the undesirable effect of an object appearing to move in a jumping manner (i.e., discontinuous movement) when adjacent lamp beads are lit and extinguished due to a wide distance between adjacent lamp beads. The applicant has found that when the phenomenon of an object appearing to move in a jumping manner occurs due to a wide distance between adjacent lamp beads, increasing the lighting frequency of the lamp beads does not overcome this undesirable effect. In a specific embodiment, the distance between adjacent LED lamp beads on the FPC body 6 (distance between the centers of the lamp beads) is less than about 5 mm, for example, about 0.5 to 5 mm, preferably about 1 to 2.5 mm.

[0055] Returning to Figures 1 and 2, the firefly lamp 100 according to the present invention further comprises a first lighting unit and a second lighting unit. The first lighting unit is provided on the top of the inner lampshade 5, and the second lighting unit is provided on the base 12 and positioned between the outer lampshade 3 and the inner lampshade 5.

[0056] According to the present invention, the first lighting unit comprises a reflective cone 51, a top white light 4, and a reflector 2. The reflective cone 51 is located in the central region of the top end of the inner lampshade 5 and has a hollow structure with an upper end that is larger than the lower end. The top white light 4 is located at the bottom of the reflective cone 51 and can be composed of, for example, 1 to 10 white lamp beads. The top white light 4 is communicatively connected to a control unit, which can control the on / off state of the top white light 4. The reflector 2 is located at the top end of the outer lampshade 3 and faces the top white light 4 at a certain distance.

[0057] As shown in Figure 6, the lower surface of the reflector 2 is configured as a reflective surface 21. This allows the top white light 4 to reflect light to the reflector 2 in conjunction with the structure of the reflective cone 51, and then reflect it to the surroundings via the reflective surface 21. The upper surface of the reflector 2 is configured as a flat surface and is used for fixed connection to the top of the inner lampshade 3. The reflective surface 21 of the reflector 2 is configured as a spherical surface and is subjected to a polished mirror plating treatment. Preferably, the reflector 2 is made of PC / ABS with a polished mirror plating. This allows the white light emitted from the top white light 4 to be reflected to the surroundings by the reflective surface 21 of the reflector 2, which not only provides an anti-glare effect but also helps to reduce light loss.

[0058] According to the present invention, the second lighting unit comprises a bottom white light 10 and a light uniformizing shield 9. The bottom white light 10 comprises an FPC element configured in the shape of a frustocone and lighting lamp beads (e.g., LED lamp beads) arranged on the FPC element. Preferably, a plurality (e.g., 8 to 100) of lighting lamp beads are evenly arranged in the circumferential direction on the FPC element. The bottom white light 10 is communicably connected to a control unit, and the control unit can control the bottom white light 10 by turning it on and off. The light uniformizing shield 9 is positioned above the bottom white light 10 and preferably parallel to the frustocone portion of the FPC element. Through holes are provided on the FPC element and the light uniformizing shield 9 through which the inner lampshade 5 can pass, thereby fitting the bottom white light 10 and the light uniformizing shield 9 into the inner lampshade 5. As shown in Figure 7, the light emitted from the bottom white light 10 is diffused into the surroundings through the light uniformizing shield 9 and the electroplated layer on the outer surface of the inner lampshade 5, improving illumination and significantly reducing light loss.

[0059] In one embodiment, the light-uniforming shade 9 can be manufactured, for example, from silicone / PC mixed with light-scattering powder, thereby achieving a light-uniforming effect and providing an anti-glare effect. Furthermore, according to one embodiment of the present invention, the second lighting unit further comprises a heat dissipation substrate 11 for effectively dissipating heat from the bottom white light 10. The heat dissipation substrate 11 is provided at the lower end of the bottom white light 10 and is fixed to the base 12. Heat dissipation The substrate 11 is preferably made of aluminum and is configured in the shape of a frustocone.

[0060] In one embodiment, the base 12 is configured in a cylindrical shape. The base 12 is provided with a control switch 15 connected to a control unit. The control switch 15 is preferably provided on the side wall of the base 12. By pressing the control switch 15, the firefly lamp 100 can be switched between off mode, top lighting mode, bottom lighting mode, and firefly mode. In off mode, the lamp body unit 50, the first lighting unit, and the second lighting unit are all turned off. In top lighting mode, only the first lighting unit is turned on. In bottom lighting mode, only the second lighting unit is turned on. In firefly mode, only the lamp body unit 50 is turned on. In bottom lighting mode and top lighting mode, the brightness of the lighting can be adjusted by rotating the control switch 15. The firefly lamp 100 further comprises a lamp body unit 50, a power supply 8 for supplying power to the first lighting unit and the second lighting unit. According to the present invention, the power supply 8 is located inside the FPC body 6, specifically inside the cylindrical inner support frame 7. The power supply 8 is positioned vertically, and its lower end is fixed to the base 12. This makes the overall structure of the firefly lamp 100 compact.

[0061] In one embodiment, a printed circuit board 13 is provided inside the base 12.

The base 12 is 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. Furthermore, the first interface 16 and the second interface 14 are spaced apart in the longitudinal direction and are both provided on the side wall opposite the control switch 15.

[0062] In one embodiment (not shown), the firefly lamp 100 further includes a gyro sensor and an accelerometer. In firefly mode, the flight state of all the fireflies can be changed by tapping, lifting, or shaking the firefly lamp 100.

[0063] The firefly lamp 100 according to the present invention can reproduce the flight and flashing effects of fireflies through the lamp body unit 50, and various flashing patterns can be realized by controlling the lamp beads inside the lamp body unit 50. Therefore, the firefly lamp 100 according to the present invention can realize flashing effects in various scenarios and effectively ensure the realism of the simulated firefly effect. At the same time, the light-transmitting but opaque inner lampshade 5 can further enhance the aesthetic appearance of the firefly lamp 100. Furthermore, the firefly lamp 100 according to the present invention can easily control the size, movement speed, and movement pattern of the fireflies on display, further enhancing the realism of the simulated firefly effect. Moreover, the firefly lamp 100 has a simple structure, is compact, easy to carry, has a simple control method, and is easy to operate.
