Description

[0002] Light Emitting Diode (LED) is more and more widely used in daily life and industrial applications.
[0003] At present, LED lamps have been widely used in people's daily lighting. Since LED light source is a light source with 180-degree angle light emission, in LED lamps, the light intensity distribution of LED light source must be changed according to different application occasions and requirements. In the existing lamps, the lamp panel in the LED lamp controls the LED light source to release light, and the light released by the LED light source is mixed in the light emission hole of the pressing block, and then is emitted from the lens on the pressing block, so that the light emitted by the LED light source achieves good light distribution effect. In order to avoid the abrasion of the pressing block to the connection between the lamp panel and the wire, a certain assembly gap is left between the pressing block and the lamp panel, which also causes an assembly gap between the light emission hole of the pressing block and the LED light source. When the LED light source emits light, part of the light will be emitted to the assembly gap, resulting in a decrease in the number of light passing through the lens and causing light loss; moreover, the light released by the LED light source also has heat, and long-time release of light to the gap will cause damage to the connection between the wire and the lamp panel, reducing the connection performance of the wire and the lamp panel.

[0036] For example, referring to Figure 2 or Figure 4 , the light emitting piece 200 comprises a circuit board 210, a light emitting chip (not shown in the figure) and a fluorescent powder film (not shown in the figure).

The circuit layer can be formed on the surface of the substrate layer by a magnetron sputtering process or the like, and a serpentine wiring design is adopted to realize a multi-chip series circuit topology.
[0037] The light emitting chips can be blue light chips or ultraviolet chips, which are arranged on the circuit board 210 in an array and are spaced apart from each other.

[0039] The phosphor film includes a transparent substrate (not shown in the figure) and a phosphor coating layer (not shown in the figure) formed on one side of the transparent substrate. The transparent substrate can be made of high-transmittance high-transmittance silicone to avoid blocking light. The transparent substrate is arranged on the circuit board 210, and the edges of the transparent substrate and the circuit board 210 are sealed to form a closed light emitting cavity.

That is, the phosphor coating layer can realize spectrum regulation, color temperature adjustment, and color rendering optimization.
[0040] In some embodiments of the present application, referring to FIGS. 1, 2, and 3, the light emitting device 200 is arranged on the lamp panel 100. The light emitting device 200 is arranged on the circuit board 210 of the lamp panel 100. The light emitting device 200 includes a plurality of light emitting chips 210 arranged on the circuit board 210.

The light emitting hole 310 is coaxial with the light emitting device 200, and the area of the light emitting hole 310 is greater than the area of the light emitting device 200. That is, the light emitting hole 310 can expose the light emitting device 200, the light emitting device 200 can emit light into the light emitting hole 310, and the light can be mixed in the light emitting hole 310.
[0041] It should be noted that the pressing block 300 can be arranged on the lamp panel 100 and can be electrically connected to the lamp panel 100 by screws, rivets, or clamping, etc. The gap is left between the side of the pressing block 300 facing the lamp panel 100 and the lamp panel 100 to avoid the pressing block 300 from damaging the connection terminals 110 or other devices on the lamp panel 100, to ensure the integrity of the connection terminals 110 and other devices, and to ensure the functional integrity of the lamp panel 100.
[0042] It can be understood that the side of the pressing block 300 facing the lamp panel 100 can be a flat surface, and a mounting gap (not shown in the figure) is formed between the pressing block 300 and the lamp panel 100 and located at the periphery of the light emitting hole 310 and communicates with the light emitting hole 310, which can avoid the connecting terminal 110 or other devices and avoid damage to the connecting terminal 110 or other devices by the pressing block 300.
[0043] In some embodiments of the present application, referring to Figure 4 As shown, the pressing block 300 includes a first pressing block 320. The first pressing block 320 includes a bottom plate 321, a first columnar structure 322, and a second columnar structure 323. The bottom plate 321, the first columnar structure 322, and the second columnar structure 323 are integrally formed structures, that is, the first pressing block 320 is formed by mold casting.
[0044] Among them, referring to Figure 4 As shown, in the perspective view, the bottom plate 321 as a whole has a square structure, and the front and back sides have sunken positions, and the middle part connects the opposite sides of the sunken positions and is arched upward. The sunken positions are provided with threaded holes corresponding to the threaded holes on the lamp panel 100, and the bottom plate 321 is connected with the lamp panel 100 by using screws or other connecting structures. The upward arching of the middle part forms the above-mentioned mounting gap between the middle part and the lamp panel 100, so as to avoid damage to the connecting terminal 110 or other devices by the first pressing block 320. The center part of the bottom plate 321 is provided with a first through hole (not shown in the figure) for exposing the light emitting element 200 located on the lamp panel 100.
[0045] In the perspective view, the first columnar structure 322 has a square-like structure. The first columnar structure 322 is arranged at the middle part of the bottom plate 321, and the first columnar structure 322 is provided with a second through hole (not shown in the figure), which is connected with the first through hole and the inner side wall of the second through hole is connected with the inner side wall of the first through hole.
[0046] Referring to Figure 4 As shown, in the perspective view, the second columnar structure 323 has a circular shape, and the second columnar structure 323 is arranged at the top surface of the first columnar structure 322. The area of the second columnar structure 323 is smaller than that of the first columnar structure 322, and the second columnar structure 323 is inscribed in the first columnar structure 322, so that the top surface of the first columnar structure 322 forms a mounting position. The second columnar structure 323 is provided with a third through hole (not shown in the figure), which corresponds to the second through hole and the first through hole, and the inner side wall of the third through hole is connected with the inner side wall of the second through hole.
[0047] It should be noted that the first through hole, the second through hole and the third through hole form the light emitting hole 310. In the direction from the bottom plate 321 to the first columnar structure 322, the areas of the first through hole, the second through hole and the third through hole gradually increase, that is, the area of the light emitting hole 310 gradually increases.
[0048] In some embodiments of the present application, referring to Figure 2 It is shown that the included angle between the inner side wall of the first through hole, the second through hole and the third through hole and the vertical center line of the lamp panel 100 ranges from 3° to 60°, and examples include 5°, 10°, 12°, 15°, 25°, 30°, 45° and 60°. It can be understood that the value of the included angle can change the light emitting efficiency of the light emitting piece 200, and different included angles can be selected according to the light emitting effect of the light emitting piece 200, so as to achieve the best light emitting efficiency and ensure the light emitting effect of the LED lamp 10.
[0049] In some embodiments of the present application, the LED lamp 10 further comprises a lens 500 arranged at the light emitting hole 310. An annular groove (not shown in the figure) is arranged on the inner side wall of the second columnar structure 323, and the lens 500 is placed in the annular groove. The light emitted by the light emitting piece 200 enters the light emitting hole 310 for light mixing, and then is emitted to the outside through the lens 500. The lens 500 can control the propagation direction, distribution and aggregation of the light.
[0050] In some embodiments of the present application, referring to Figure 4 It is shown that the pressing block piece 300 further comprises a second pressing block 330. The second pressing block 330 comprises a mounting plate 331 and an annular table 332. In the top view, the structure of the mounting plate 331 is the same as the size of the area of the first columnar structure 322. The mounting plate 331 is arranged on the top surface of the first columnar structure 322, and the mounting plate 331 and the mounting position correspondingly arranged position and the mounting position of the first columnar structure 322 are provided with threaded holes, and the mounting plate 331 and the first columnar structure 322 are connected and fixed by screws or other connecting structures, so as to fix the second pressing block 330 on the first pressing block 320. The annular table 332 surrounds the second columnar structure 323, and the top surface of the annular table 332 is provided with an annular stopper 333, the annular stopper 333 is located on the top surface of the second columnar structure 323 and extends towards the center position of the light emitting hole 310, and the annular stopper 333 can limit the displacement of the lens 500 in the axial direction of the light emitting hole 310, so as to fix the lens 500 between the first pressing block 320 and the second pressing block 330, and avoid the lens 500 from falling off.
[0051] In some embodiments of the present application, referring to Figure 2 and Figure 3 It is shown that the reflecting piece 400 is arranged on the surface of the lamp panel 100 provided with the light emitting piece 200, and is arranged outside the light emitting piece 200 and located in the mounting gap.
[0052] In some embodiments of the present application, the reflecting member 400 is located in the gap between the inner wall of the light emitting hole 310 and the outer wall of the light emitting member 200, i.e. between the light emitting hole 310 and the light emitting member 200. As shown in Figure 2 As shown, the reflecting member 400 is arranged around the outer edge of the light emitting member 200. For example, the reflecting member 400 is arranged around the outer wall of the light emitting cavity. In the thickness direction of the lamp panel 100, the thickness of the reflecting member 400 is greater than the thickness of the light emitting member 200, and the reflecting member 400 can reflect the light emitted by the light emitting member 200 into the light emitting hole 310, so that the light emitted by the light emitting member 200 to the gap between the pressing block 300 and the lamp panel 100 can be recycled into the light emitting hole 310 of the pressing block 300, reducing light loss and improving light utilization. In addition, by blocking the light from entering the gap between the pressing block 300 and the lamp panel 100, the direct light to the connection between the wire and the lamp panel 100 can be effectively avoided, the temperature of the gap can be effectively reduced, the temperature of the connection between the wire and the lamp panel 100 can be reduced, and the connection performance of the connection terminal 110 of the wire and the lamp panel 100 can be ensured, so as to ensure the stability of the LED lamp 10.
[0053] In some embodiments of the present application, the reflecting member 400 can also be arranged between the bottom surface of the bottom plate 321 and the top surface of the lamp panel 100. In the thickness direction of the lamp panel 100, the thickness of the reflecting member 400 is greater than the thickness of the light emitting member 200, and the reflecting member 400 can reflect the light emitted by the light emitting member 200 into the light emitting hole 310, so as to reduce light loss and improve light utilization.
[0054] It can be understood that in some embodiments, the bottom of the first pressing block 320 extends downward to form an annular reflecting portion (not shown in the figure), which forms a reflecting cavity. The inner wall of the annular reflecting portion is provided with a diffuse reflection layer, and part of the light emitting member 200 is located in the reflecting cavity. The light emitted by the light emitting member 200 can pass through the diffuse reflection layer of the annular reflecting portion and be diffusely reflected into the light emitting hole 310, so as to reduce light loss, improve light utilization, reduce the temperature in the gap, and improve the connection performance of the wire and the lamp panel 100.
[0055] It is worth mentioning that in the thickness direction of the lamp panel 100, the top end of the reflecting member 400 can extend into the light emitting hole 310 or not, as long as the reflecting member 400 can block the light from entering the gap between the pressing block 300 and the lamp panel 100.
[0056] In some embodiments of the present application, as shown in Figure 3 As shown, in the thickness direction of the lamp panel 100, the top end of the reflecting member 400 extends into the light emitting hole 310, so as to better block the light of the light emitting member 200 from entering the gap between the pressing block 300 and the lamp panel 100, reduce light loss and heat output, and improve light utilization.
[0057] It should be noted that the reflecting member 400 can be integrally formed with the lamp panel 100, or can be detachably connected with the lamp panel 100, for example, by bonding, clamping or screwing.
[0058] For example, one side of the reflecting member 400 facing the lamp panel 100 and one side of the lamp panel 100 provided with the light emitting member 200 are provided with adhesive layers (not shown in the figure), and the reflecting member 400 is bonded with the lamp panel 100 through the adhesive layers, so that the lamp panel 100 and the reflecting member 400 are detachably connected, facilitating replacement or installation of the reflecting member 400.
[0059] For another example, one of the reflecting member 400 and the lamp panel 100 is provided with a buckle (not shown in the figure), and the other is provided with a buckle hole (not shown in the figure) matched with the buckle, and the buckle can be clamped in the buckle hole, that is, the reflecting member 400 and the lamp panel 100 can be detachably connected through the buckle and the buckle hole.
[0060] For another example, the reflecting member 400 and the lamp panel 100 are both provided with threaded holes (not shown in the figure), the threaded holes on the reflecting member 400 correspond to the threaded holes on the lamp panel 100, and a screw member is arranged in the threaded holes on the reflecting member 400 and the threaded holes on the lamp panel 100, so as to detachably connect the reflecting member 400 and the lamp panel 100.
[0061] It can be understood that the lamp panel 100 and the reflecting member 400 are detachably connected by bonding, clamping or screwing, which can facilitate replacement or installation of the reflecting member 400.
[0062] In some embodiments of the present application, as shown in Figure 2 and Figure 3 The reflecting member 400 includes a flexible reflecting body 410, and the flexible reflecting body 410 is vertically arranged on the lamp panel 100.
[0063] It can be understood that the flexible reflecting body 410 has a certain flexibility and elasticity, which can avoid rigid collision between the pressing block 300 and the reflecting member 400, ensure the integrity of the pressing block 300 and the reflecting member 400, and also avoid collision between the pressing block 300 and the light emitting member 200 through the flexible reflecting body 410, ensuring the integrity of the light emitting member 200.
[0064] In some embodiments of the present application, the reflecting member 400 includes a reflecting carrier and diffused diffused reflection optical particles in the reflecting carrier. The reflecting carrier can be hard or similar to the aforementioned flexible reflecting body 410. The optical particles diffused in the reflecting carrier can make the formed reflecting member 400 have higher reflection and scattering properties, and can improve the light output luminance and uniformity.
[0065] The diffuse reflection optical particles include one or more of a combination of barium sulfate particles, titanium oxide particles, zirconium oxide particles, and aluminum oxide particles, so that the reflector 400 has high reflectivity and scattering.
[0066] In some embodiments of the present application, the flexible reflection body 410 is uniformly filled with barium sulfate particles to improve light reflectivity and scattering, and to improve light efficiency and uniformity.
[0067] In some embodiments of the present application, the flexible reflection body 410 is a resin piece, a plastic piece, a rubber piece, a silica gel piece, or a high polymer material piece (polyethylene, polypropylene, etc. thermoplastic material piece), that is, the flexible reflection body 410 can be made of resin, plastic, rubber, silica gel, or high polymer material (polyethylene, polypropylene, etc. thermoplastic material), so that the flexible reflection body 410 has a certain flexibility and elasticity, avoiding damage caused by collision with the pressing block 300. Similarly, the reflection carrier can be made of silica gel, resin, plastic, rubber, or high polymer material, etc. suitable as a material for the diffuse reflection optical particle carrier.
[0068] It is worth mentioning that the reflector 400 as a whole is white to reduce light absorption and improve the reflectivity and scattering of the reflector 400.
[0069] It can be understood that the flexible reflection body 410 can be white, or the flexible reflection body 410 can be white after being filled with optical particles.
[0070] In the present application: when the light emitting piece 200 is powered on, the light emitted by the light emitting chip array passes through the phosphor coating and forms white light of a target color temperature after mixing light in the light outlet hole 310. When the light is guided by the diverging light outlet hole 310 structure of the pressing block 300, the inner wall of the light outlet hole 310 directs the light, and the reflector 400 redirects the stray light in the gap to the light outlet hole 310, reducing light loss and ensuring the light efficiency of the LED lamp 10. In this process, the reflector 400 can also isolate the heat generated by the light emitting piece 200, avoid heat transfer to the wire connection area, control the solder joint between the wire and the lamp panel 100 at a certain temperature, and ensure the connection stability of the wire and the lamp panel 100.
[0071] In addition, when optical adjustment is needed, the lens 500 between the first pressing block 320 and the second pressing block 330 can be quickly disassembled to replace the lens 500 with a different light distribution angle.
