Description

Technical Field

[0001] This specification relates to the field of lighting technology, and in particular to a light-emitting device. Background Technology

[0002] Light guide structures are widely used to achieve uniform surface or linear light sources, commonly found in commercial displays, home décor, and ambient lighting. Their core objective is to transform light emitted from point or line light sources into a uniformly bright optical output with minimal differences in brightness, via a light guide medium. Currently, conventional light guide structures typically rely on regular shapes (such as uniform straight strips or flat plates) combined with evenly distributed LEDs. As long as the light sources are spatially symmetrical and have consistent density, a roughly uniform light output effect can be achieved by leveraging the scattering and conduction properties of the light guide material itself. However, how to achieve the same lighting effect while saving costs and simplifying the design remains a pressing issue.

[0003] Therefore, it is necessary to provide a light-emitting device that can save costs while ensuring light emission effect and improving user experience. Summary of the Invention

Figure 2 This is based on some embodiments shown in this specification. Figure 1 A schematic diagram of the supporting components. Figure 3 This is a schematic diagram illustrating the connection relationship between the light-emitting component and the support component according to some embodiments of this specification.

[0020] In some embodiments, such as Figures 1-3 As shown, the light-emitting device includes: a light-emitting component 1 and a support component 2.

[0021] The light-emitting component 1 includes a heat sink 11, an adapter plate 12, and at least three sets of lamps 13. The heat sink 11 includes at least three mounting surfaces, and one set of lamps 13 is mounted on one mounting surface. Each set of lamps 13 includes multiple staggered and tilted lamp beads, and the tilt angles of adjacent lamp beads are different. The control lines of the at least three sets of lamps 13 are connected to the adapter plate 12. The support component 2 includes a base 21 and a lamp strip fixing seat 22. The lamp strip fixing seat 22 is disposed on the base 21, the adapter plate 12 is installed in the lamp strip fixing seat 22, and the heat sink 11 is connected to the lamp strip fixing seat 22.

[0022] Light-emitting component 1 refers to the component used to emit light.

[0023] A heat sink is a tubular component used to absorb and dissipate heat generated by LED chips during operation. In some embodiments, the heat sink can be made of materials with good heat dissipation properties, such as metal, flexible silicone, or plastic / polymer composite materials. The cross-sectional shape of the heat sink can be a regular or irregular polygon, such as a quadrilateral, hexagon, or octagon.

[0024] In some embodiments, such as Figure 1and Figure 2 As shown, the heat pipe 11 is a hollow pipe, and the center of the heat pipe 11 includes a through hole 111 for wiring.

[0025] A through hole 111 refers to a hole or channel that runs through the entire length of the heat sink 11. By setting through holes 111 on the heat sink 11, the heat sink can hide the control lines and peripheral lines 4 of at least 3 sets of lamp groups 13, making the appearance of the light-emitting component 1 more concise.

[0026] Figure 4 This is a partial cross-sectional view of the heat pipe shown in some embodiments of this specification.

[0027] In some embodiments, such as Figure 4 As shown, the surface of the heat sink 11 is designed with concave and convex surfaces, forming several mounting grooves 112-115 for mounting the lamp assembly 13. The bottom surface of the mounting grooves 112-115 is inclined at an angle to the axis of the heat sink 11.

[0028] The concave-convex surface design refers to the fact that the surface of the heat pipe is not smooth and flat, but is composed of alternating convex and concave surfaces.

[0029] Mounting grooves 112-115 refer to specific grooves or slots formed by recesses on the surface of the heat dissipation tube, used to fix the lamp assembly 13. The bottom surface of mounting grooves 112-115 refers to the supporting surface that directly contacts the bottom of mounting grooves 112-115 with the lamp assembly 13.

[0030] The axis of a heat pipe refers to a virtual straight line running along the longitudinal center of the heat pipe, representing the geometric axis of symmetry of the pipe body. The longitudinal center refers to the ideal trajectory line formed by the set of all centroidal points (geometric centers) of the cross-sections constituting the geometric axis of symmetry of the object. The tilt angle here refers to the angle between the bottom surface of the mounting groove 112-115 and the axis of the heat pipe. See the description below for more information on the tilt angle.

[0031] The design of the concave and convex surfaces creates multiple inclined mounting grooves, which securely embed the lamp assembly into the heat dissipation pipe, reducing the need for additional fasteners. The bottom surface of the mounting grooves is in close contact with the lamp assembly, accelerating the transfer of heat from the lamp assembly to the heat dissipation pipe. At the same time, the tilt angle can improve the accuracy of controlling the illumination direction of the lamp assembly.

[0032] In some embodiments, the heat sink 11 has a hexagonal cross-sectional shape, and correspondingly, the heat sink 11 has six planes along its longitudinal center. When the number of lamp groups is set to 3, that is, as shown... Figure 1 and Figure 2 As shown, when the three groups of lights are the first group 131, the second group 132 and the third group 133, three planes spaced apart in the heat sink 11 can be selected as the mounting surfaces of the lights.

[0033] To balance the lighting effect and the cost of the lamp assembly, this embodiment uses three lamp assemblies as an example. In practice, the number of lamp assemblies can be increased or decreased according to needs.

[0034] In some embodiments, the heat sink 11 is a metal pipe. For example, the heat sink 11 is an aluminum pipe, a copper pipe, etc.

[0035] The mounting surface refers to the flat surface on the heat dissipation pipe used for mounting the lamp assembly 13.

[0036] In some embodiments, the mounting surface includes a mounting groove with notches, and the distance between two adjacent notches corresponds to the distance between two adjacent LED beads.

[0037] Mounting slots are elongated grooves, channels, or tracks machined or shaped on the mounting surface. They are used to accommodate and secure the substrate, preventing lateral movement.

[0038] In some embodiments, two raised ribs can be provided on both sides of the mounting surface along the longitudinal center of the heat sink, and the mounting surface portion between the two ribs constitutes the mounting groove. The width between the two ribs is slightly larger than the width of the substrate. The mounting groove can be configured according to actual needs.

[0039] A notch is a recess, window, or hole that is spaced out on the side wall or edge (such as a rib) of the mounting groove. Notches are used to observe and confirm that the LED beads are aligned properly during installation.

[0040] The distance between two adjacent notches refers to the dimension along the length of the mounting groove (i.e., along the longitudinal center of the heat sink) from the center (or edge) of one notch to the center (or edge) of the next nearest notch.

[0041] The distance between two adjacent notches corresponds to the distance between two adjacent LED beads, meaning that each notch is precisely aligned with the installation position of one LED bead.

[0042] The adapter board 12 refers to the circuit board that serves as the hub for electrical connections. The adapter board 12 is used to distribute and transfer external power and control signals to each lamp group 13.

[0043] Lamp group 13 refers to a light-emitting unit composed of multiple LED chips. Each lamp group 13 contains multiple LED chips and their matching substrate (such as an aluminum substrate).

[0044] A light chip is a miniature electronic component that can directly convert electrical energy into light energy, such as a light-emitting diode (LED) chip and its package. In some embodiments, the light chips in a group of light clusters 13 may have the same or different light emission colors, and the light emission colors of the light chips in different light clusters 13 may be the same or different.

[0045] A substrate refers to a component that carries and fixes multiple LED chips and provides electrical connections and heat dissipation paths. In some embodiments, the substrate is made of metal (such as aluminum, copper, or aluminum-clad copper), ceramic (such as alumina, aluminum nitride, or beryllium oxide), or flexible material (such as polyimide).

[0046] Staggered arrangement refers to multiple LEDs within the same LED group 13 not being on a straight line, but rather staggered from each other. Tiltd mounting means that the LEDs are not mounted perpendicularly to the substrate, but rather their luminous axis forms a certain angle with the normal to the mounting surface, i.e., a tilt angle. The luminous axis is a virtual reference line used to characterize the direction of the LED's luminous intensity distribution. The mounting surface normal is a virtual line perpendicular to the point where the mounting surface contacts the LED.

[0047] In some embodiments, the tilt angle of the LED chip ranges from 15° to 45°. For example, the tilt angle of the LED chip is 15°. Another example is a tilt angle of 30°. Yet another example is a tilt angle of 45°. The tilt angle of the LED chip can be set according to actual needs.

[0048] The control line refers to the wire connecting the LED bead and the adapter board 12, which is responsible for transmitting electrical energy and possible control signals (such as dimming and color adjustment signals).

[0049] The support component 2 is used to support, fix and connect the light-emitting component 1 to the final use environment (such as a wall, ceiling, or light pole).

[0050] The base 21 is the basic component supporting the assembly 2 and is used to directly contact the mounting surface (such as a wall or floor) of the final use environment.

[0051] The light strip holder 22 refers to the structure located on the base 21 for accommodating and fixing the light-emitting component 1.

[0052] In some embodiments, such as Figure 3 As shown, the base 21 includes a housing 211 and a receiving cavity 212, and the light strip fixing seat 22 is embedded in the housing 211.

[0053] The housing 211 refers to the outer shell of the base 21, which is a component that constitutes the base 21 and determines its appearance and main structural shape. In some embodiments, the base 21 may be made of plastic, metal, or the like. The base 21 may be cylindrical or similar in shape.

[0054] In some embodiments, the light strip holder 22 can be embedded in the housing 211 in various ways, such as snap-fit ​​embedding, slide rail embedding, etc.

[0055] The accommodating cavity 212 refers to a hollow space inside the housing 211. The accommodating cavity 212 is used to accommodate, conceal, and protect other components, such as controllers.

[0056] In some embodiments, the light-emitting component 1 further includes a controller (not shown in the figure), which is connected to at least three sets of lamps 13 based on the adapter plate 12, and the controller is disposed in the receiving cavity 212 of the base 21.

[0057] A controller is an electronic module that integrates a microprocessor (MCU), drive circuits, communication chips, etc. In some embodiments, the controller is first connected to the adapter board 12, and then the adapter board 12 is connected to each lamp group 13 through control lines.

[0058] In some embodiments, such as Figure 1 As shown, the through hole 111 of the heat pipe 11 can be used to lay out the peripheral cable 4.

[0059] Peripheral line 4 refers to the control line of external devices (such as power line or signal line).

[0060] In some embodiments, through the deployment of peripheral line 4, the controller can share with or synchronize with the operating signals of external devices to control the illumination of the lamp group 13. Taking an audio device as an example, the operating signal of the external device can be an audio signal, and the controller can control the illumination or dimming frequency of the lamp group 13 based on the frequency, rhythm, etc. of the audio signal.

[0061] In some embodiments, the external device may also be a multimedia device such as a computer, television, power amplifier, or AV receiver.

[0062] By setting up a controller to control the light emission of the light group, it is beneficial to increase the interest and variability of the light-emitting device.

[0063] In some embodiments of this specification, the other components of the light-emitting device can be effectively hidden by setting up a housing and a receiving cavity, thereby increasing the overall aesthetics; by embedding the light strip mounting bracket into the housing, the accuracy and stability of the installation position, angle and direction of the light strip (light-emitting component) can be ensured, reducing the risk of shaking or displacement.

[0064] When the external power is turned on, the controller starts to work. The controller first generates the corresponding control signal and transmits it to the adapter board 12 through the cable; the adapter board 12 then distributes the control signal to the control line of each group of lamps 13 connected to it according to the circuit design; after receiving the signal, each group of lamps 13 drives the multiple lamp beads on it to emit light.

[0065] Due to the staggered arrangement and different tilt angles of the LED beads, the light emitted by each LED bead is projected in a specific direction; multiple beams of light emanating from various mounting surfaces of the heat sink 11 at different angles converge and overlap in space. The staggered arrangement results in a fine texture in the near-field light spot, while the different tilt angles allow the far-field light spots to blend naturally, ultimately forming a broad, uniform, and high-quality light spot without abrupt boundaries between light and dark areas in the target illumination area; the heat generated when the LED beads emit light is rapidly conducted to the heat sink 11 through its substrate. The heat sink 11 utilizes its metal material and large surface area to evenly distribute the heat. The heat is further conducted from the heat sink 11 to the LED strip mounting base 22, and finally dissipated into the environment through the entire structure of the support assembly 2, thereby ensuring that the LED beads operate stably for a long time at a safe temperature.

[0066] In some embodiments of this specification, staggered and tilted placement can effectively reduce the number of LEDs, lower material and production costs, while eliminating the brightness difference of traditional single-layer arrangement and reducing glare; using metal tubes as heat dissipation tubes can directly conduct heat to the metal tubes for heat dissipation, achieving high coverage with low power consumption and low heat dissipation pressure; the modular design eliminates the need for complex assembly structures, facilitating installation, maintenance and disassembly.

[0067] In some embodiments, such as Figure 1 As shown, the light-emitting device also includes a lampshade 3, which is fitted over the light-emitting component 1, and the bottom of the lampshade 3 is connected to the base 21.

[0068] The lampshade 3 is a hollow shell fitted over the outermost layer of the light-emitting device. In some embodiments, the lampshade 3 can be made of a light-transmitting or light-diffusing material (such as glass, plastic, or fabric). The shape of the lampshade 3 can be cylindrical, conical, spherical, square, etc. For example, as shown... Figure 1 As shown, lampshade 3 is funnel-shaped: large at both ends and small in the middle.

[0069] In some embodiments, the bottom of the lampshade 3 can be connected to the base 21 in various ways, such as threaded connection, snap-fit ​​connection, flange connection, etc.

[0070] In some embodiments of this specification, the use of a lampshade can precisely control the beam angle to achieve a focusing or flooding effect, so that light energy can be used efficiently in the target area, avoiding light pollution and energy waste; by setting the lampshade and light-emitting components separately, the same light-emitting component can be matched with different lampshades to achieve different light guiding effects.

[0071] Certain features, structures, or characteristics in one or more embodiments of this specification may be appropriately combined.

It should be understood that such numbers used in the description of embodiments are sometimes modified by the terms "approximately," "approximately," or "generally." Unless otherwise stated, "approximately," "approximately," or "generally" indicates that the numbers are allowed to vary by ±20%.
