Description

[0001] This utility model is a divisional application filed with the China Patent Office on May 30, 2023, application number 2023213519976, and invention name “A LED lighting device” Technical Field

[0002] The utility model belongs to the technical field of LED lighting devices, and specifically relates to an LED lighting device. Background Art

[0003] LED lighting is widely used because of its advantages of energy saving and long life. LED lamps in the prior art commonly include flat panel lamps and grille lamps.

[0004] Flat panel lights in the prior art usually include a light bar, a bottom frame, a light guide plate and a diffuser plate. The light bar is arranged on the side of the bottom frame to provide lateral light output. The light emitted by the light bar passes through the light guide plate and then is emitted from the diffuser plate. Flat panel lights in the prior art have the following disadvantages: the light emitted by the light bar has a large light loss after passing through the light guide plate and the diffuser plate, resulting in a low light output efficiency of the flat panel lights; the light guide plate has a high cost, which is not conducive to the cost control of the flat panel lights; and the glare control of the flat panel lights is relatively general.

[0005] The grille lamp in the prior art includes a bottom frame, a light source (the light source can be a fluorescent tube or an LED tube) and a grille. The light source is fixed on the bottom frame, and a grille is set on the light emitting side of the light source. The light source of the grille lamp in the prior art is replaceable, which can reduce the long-term use cost. However, the grille lamp in the prior art has the following disadvantages: the way of setting the grille is not conducive to the height control of the grille lamp, which increases the packaging and transportation costs; the cost of the grille is relatively high, which is not conducive to the cost control of the whole lamp; when setting the grille, light loss occurs at both the lamp tube and the grille, and the light output efficiency is not high; when replacing the light source, it is necessary to open the grille first, then replace the light source, and finally install the grille, so the light source replacement is more cumbersome; the height of the whole grille lamp is relatively high, which is not conducive to the control of packaging and transportation costs.

[0006] In summary, in view of the deficiencies and defects of LED lighting devices in the prior art, how to design LED lighting devices to solve the glare problem is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0056] like Figures 1 to 10 As shown, an LED lighting device is provided in an embodiment of the utility model, and the LED lighting device includes: a base 1 and a photoelectric module 2, wherein the photoelectric module 2 is detachably fixed to the base 1, so that the photoelectric module 2 can be replaced when damaged, so as to reduce the overall use cost of the LED lighting device.

[0057] See also Figure 2 , Fig. 9 and Fig.10In this embodiment, the base 1 has a bottom plate 11 and a side wall 12. The side wall 12 is disposed at the outer edge of the bottom plate 11. The side wall 12 extends relative to one side of the bottom plate 11 to form a cavity 101 between the side wall 12 and the bottom plate 11. In some embodiments, at least a portion of the optoelectronic module 2 in the thickness direction is accommodated in the cavity 101. In some embodiments, at least 80% of the optoelectronic module 2 in the thickness direction is accommodated in the cavity 101. In some embodiments, the optoelectronic module 2 is completely accommodated in the cavity 101 in the thickness direction.

[0058] In some embodiments, the base 1 may not have the concave cavity, that is, the base 1 only has the bottom plate 11 , and the optoelectronic module 2 is detachably fixed to the bottom plate 11 of the base 1 .

[0059] The base 1 can be made of metal, such as iron or stainless steel, to increase its heat dissipation performance. In some embodiments, the base 1 is an integrated structure, and the side wall 12 is directly bent relative to the bottom plate 11. In some embodiments, the base 1 is an integrated structure, which is directly formed by stamping or stretching, so that it has good structural strength. In some embodiments, the base 1 can also be made of plastic.

[0060] In some embodiments, the base 1 has a split structure, including a bottom plate 11 and a side wall 12 that are independent of each other. The bottom plate 11 and the side wall 12 are independently manufactured and then assembled with each other, so as to optimize the assembly of the LED lighting device. For example, in some embodiments, the optoelectronic module 2 and the bottom plate 11 can be assembled first, and then the side wall 12 can be assembled to the assembly formed by the optoelectronic module 2 and the bottom plate 11, thereby completing the assembly of the LED lighting device.

[0061] See also Figure 1 , Figure 5 , Fig. 9 and Fig.10In order to increase the strength of the base 1, a reinforcing unit 13 may be provided on the base 1. The reinforcing unit 13 may include a plurality of first reinforcing structures 131 and a plurality of second reinforcing structures 132, and the first reinforcing structures 131 and the second reinforcing structures 132 may be connected. In some embodiments, the first reinforcing structure 131 and the second reinforcing structure 132 may be arranged perpendicularly or substantially perpendicularly to each other, wherein the first reinforcing structure 131 is extended along the length direction of the LED lighting device (the direction in which the circuit board 32 extends). In some embodiments, the first reinforcing structure 131 protrudes toward the back side of the base 1 (the side where no light source is provided), and similarly, the second reinforcing structure 132 protrudes toward the back side of the base 1, and the first reinforcing structure 131 and the second reinforcing structure 132 are connected on the front side of the base 1. The first reinforcing structure 131 and the second reinforcing structure 132 may be integrally formed on the base 1, such as by stretching or stamping, so that the first reinforcing structure 131 and the second reinforcing structure 132 protrude toward the back side of the base 1. Furthermore, the wall thickness of the first reinforcement structure 131 and the second reinforcement structure 132 is substantially the same as the wall thickness of the rest of the base 1. In other words, without additional material being provided on the bottom plate 1, the overall structural strength of the base 1 can be improved by providing the first reinforcement structure 131 and the second reinforcement structure 132. In some embodiments, the first reinforcement structure 131 and the second reinforcement structure 132 can be independent components and attached to the base 1 to enhance the structural strength of the base 1.

[0062] See also Fig. 9 and Fig.10 The distance between adjacent first reinforcement structures 131 is between 10 mm and 30 mm.

[0063] See also Figures 1 to 8 The optoelectronic module 2 in this embodiment includes a light source 3, an optical component 4 and a carrying unit 5, wherein the light source 3 is arranged on the carrying unit 5, and the optical component 4 is arranged on the light path of the light source 3 to perform light processing on the light generated by the light source 3.

[0064] The light source 3 in this embodiment can be fixed to the bearing unit 5 directly or indirectly. Specifically, the light source 3 includes an LED lamp bead 31 and a circuit board 32, wherein the LED lamp bead 31 is fixed on the circuit board 32, and the light source 3 is directly fixed to the bearing unit 5 through the circuit board 32. In some embodiments, the circuit board 32 is directly fixed to the bearing unit 5 by bonding. In some embodiments, the light source 3 can be clamped on the bearing unit 5 through the circuit board 32. In some embodiments, the light source 3 can be directly fixed to the bearing unit 5 by welding. In the above embodiments, the light source 3 forms a heat conduction path with the bearing unit 5, so that the heat generated by the LED lamp bead 31 when working can be quickly thermally conducted to the bearing unit 5, and the bearing unit 5 is in contact with the base 1, so as to conduct the heat to the base 1 for heat dissipation. In some embodiments, the LED lamp bead 31 on the circuit board 32 is provided with one column. In some embodiments, the LED lamp bead 31 on the circuit board 32 is provided with two columns, and the two columns of LED lamp bead 31 have the same or different color temperatures, and can also have the same or different light colors. That is, at least one column of LED lamp beads 31 is arranged on the circuit board 32, and the LED lamp beads 31 in the at least one column can be controlled to light up or off at the same time, or can be controlled to light up or off independently, or a combination of the two, so that the LED lighting fixture can adapt to a wider range of usage scenarios.

[0065] The optical component 4 in this embodiment includes a first optical component 41 and a second optical component 42, which are respectively used to process the light emitted by the light source 3; the first optical component 41 is covered on the supporting unit 5 and is configured to redirect at least a portion of the light emitted by the light source 3, and the second optical component 42 is arranged on the first optical component 41 and is configured with one or more of the functions of light transmission, light diffusion, light refraction or light reflection.

[0066] In some embodiments, the first optical element 41 is configured with one or more functions of light transmission, light diffusion, light refraction or light reflection.

[0067] In some embodiments, the first optical element 41 and the second optical element 42 are separately provided, and the second optical element 42 is provided on the first optical element 41 during the assembly process.

[0068] In some embodiments, the first optical component and the second optical component 42 are integrally provided, that is, during the manufacturing process, the second optical component 42 is directly molded on the first optical component 41 . This method can simplify the assembly process to a certain extent and improve the structural strength of the optical component 4 .

[0069] In some embodiments, the first optical element 41 is made of a material with light reflection function to reflect at least a portion of the light generated by the light source 3 when it is working. In some embodiments, the first optical element 41 is made of a material with light reflection and light diffusion function to reflect and diffuse at least a portion of the light generated by the light source 3 when it is working. Figure 5 , a plurality of optical units 411 are arranged on the first optical element 41 .

[0070] The light source 3 includes a plurality of LED arrays 33, and the LED arrays 33 include one or more LED lamp beads 31. In this embodiment, each LED array 33 includes a plurality of LED lamp beads 31. The optical unit 411 corresponds to the LED array 33 of the light source 3. That is, the LED array 33 and the optical unit 411 are configured one-to-one, and the same number of the two are provided.

[0071] In some embodiments, the number of LED arrays 33 is less than the number of optical units 411 .

[0072] In some embodiments, the number of LED arrays 33 is greater than the number of optical units 411 .

[0073] The optical unit 411 includes a light exit hole 4111, and the light exit hole 4111 exposes the corresponding LED array 33 to the optical unit 411. That is, the optical unit 411 will not block the optical axis direction of the LED lamp beads 31 of the LED array 33, and will not cause light loss caused by excessive light passing through different media.

[0074] The optical unit 411 is attached to the surface of the circuit board 32 of the light source 3 so that there is no gap between the circuit board 32 and the wall of the outer edge of the light exit hole 4111 in the direction of the optical axis of the LED lamp bead 31, so as to prevent light from entering the gap and causing light loss. In some embodiments, the distance between the optical unit 411 and the surface of the circuit board 32 of the light source 3 is less than 1 mm (the distance between the surface of the circuit board 32 and the wall of the outer edge of the light exit hole 4111 in the direction of the optical axis of the LED lamp bead 41 is less than 1 mm), thereby reducing the gap between the circuit board 42 and the wall of the outer edge of the light exit hole 4111 where light enters, thereby controlling light loss.

[0075] In some embodiments, a light reflecting layer is disposed on the circuit board 32 , or the circuit board 32 itself has light reflecting capability, and can reflect a portion of the light emitted by the LED array 33 , thereby further controlling light loss.

[0076] The optical unit 411 includes a first optical wall 4112 and a second optical wall 4113, wherein the first optical wall 4112 is arranged on both sides of the width direction of the circuit board 32, and the second optical wall 4113 is arranged on the length direction of the circuit board 32 and is located on both sides of the LED array 33, that is, the first optical wall 4112 and the second optical wall 4113 are connected end to end to form the light exit hole 4111. In one embodiment of the present application, the two first optical walls 4112 and the two second optical walls 4113 are connected end to end to form an annular structure, and the light exit hole 4111 is located in the annular structure; it can also be said that the annular structure is the light exit hole 4111. The first optical wall 4112 and the second optical wall 4113 can be configured with a reflective and / or light-transmitting function to redirect the direct or indirect light emitted by the LED lamp bead 31 to improve the light type of the light. The vertical distances between the first optical wall 4112 and the second optical wall 4113 and the LED array 33 gradually increase along the light emitting direction of the LED array 33 .

[0077] After the second optical element 42 covers the first optical element 41, an optical cavity consisting of the first optical wall 4112, the second optical wall 4113 and the second optical element 42 is formed. The light generated by the LED lamp bead 31 when it is working is finally emitted from the second optical element 42. In this embodiment, at least part of the luminous flux generated by the LED array 33 (light source 3) when it is working only passes through one optical layer (excluding air) and is emitted from the LED lighting device, which can reduce the light loss caused by passing through multiple optical layers and improve the light extraction efficiency. In other words, at least part of the luminous flux generated by the LED array 33 when it is working directly passes through the second optical element 42 and is emitted from the LED lighting device (without one or more reflections, or without reflections from the first optical element 41).

[0078] In some embodiments, after the second optical element 42 covers the first optical element 41, an optical cavity consisting of the first optical wall 4112, the second optical wall 4113 and the second optical element 42 is formed, and the light generated by the LED lamp bead 31 when working is finally emitted from the second optical element 42. In this embodiment, at least 50% of the luminous flux generated by the LED array 33 (light source 3) when working passes through only one optical layer (excluding air) and is emitted from the LED lighting device, which can reduce the light loss caused by passing through multiple optical layers and improve the light extraction efficiency. In other words, at least 50% of the luminous flux generated by the LED array 33 when working directly passes through the second optical element 42 and is emitted from the LED lighting device (without one or more reflections, or without reflections from the first optical element 41).

[0079] In some embodiments, the light generated by the LED lamp bead 31 when it is working is finally emitted from the second optical element 42. In this embodiment, all the luminous flux generated by the LED array 33 (light source 3) when it is working only passes through one optical layer (excluding air) and is emitted from the LED lighting device, which can reduce the light loss caused by passing through multiple optical layers and improve the light extraction efficiency. In other words, all the luminous flux generated by the LED array 33 when it is working directly passes through the second optical element 42 and is emitted from the LED lighting device (without one or more reflections, or without reflections from the first optical element 41). In some embodiments, the second optical element 42 can be configured to have a light diffusion function (for example, the second optical element 42 has a light diffusion function due to its own material properties, such as using an acrylic material) to improve the uniformity of the light output. In some embodiments, a microarray structure is provided on the second optical element 42 to redirect the light.

[0080] In some embodiments, the light source 3 may be composed of filaments, and a plurality of filaments are arranged in a certain pattern, such as parallel, cross, ring, nested, etc., and then fixed to the supporting unit 5.

[0081] In this embodiment, the angle A between the two groups of first optical walls 4112 on both sides of the width direction of the circuit board 32 and the angle B between the two groups of second optical walls 4113 on both sides of the length direction of the circuit board 32 are both smaller than the beam angle C of the LED lamp beads 31. Therefore, a portion of the light generated when at least a portion of the LED lamp beads 31 in the LED array 33 are lit may directly hit the first optical wall 4112 and the second optical wall 4113, so as to be redirected by the first optical wall 4112 and the second optical wall 4113 to improve the light output pattern. In addition, the first optical wall 4112 and the second optical wall 4113 can also redirect the light that is reflected and hits the first optical wall 4112 and the second optical wall 4113.

[0082] In some embodiments, the aforementioned carrying unit 5 may not be provided, and the light source 3 may be directly provided on the first optical element 411. That is, the first optical element 411 replaces the carrying unit 5, and has both optical and structural functions.

[0083] For example, in some embodiments, the first optical element 411 has a mounting opening or an extension portion corresponding to the light source 3 for fixing the light source 3 .

[0084] The optoelectronic module 2 in this embodiment may also be provided with a power supply 6, which is electrically connected to the light source 3 to provide power to the light source. The power supply 6 is disposed between the optical component 4 (the first optical component 41) and the carrier unit 5, so that the power supply 6 does not occupy additional height space of the optoelectronic module 2, which is conducive to controlling the overall height size of the optoelectronic module 2.

[0085] In this embodiment, an accommodation space is formed between two adjacent rows of first optical walls 4112 of the first optical element 41 for placing the power supply 6. Therefore, when the power supply 6 is arranged, it will not occupy additional height space of the LED lighting device, thereby facilitating the control of the overall height dimension of the LED lighting device.

[0086] In this embodiment, an electrical connection terminal 601 is disposed on the base 1 , and the electrical connection terminal 601 is electrically connected to the power source 4 , and the electrical connection terminal 601 is used to connect to external power.

[0087] In some embodiments, the power source 4 has an electrical connection terminal 601, which is disposed on the back side of the carrier unit 5, that is, the other side of the carrier unit 5 opposite to the optical component 4. The base 1 in this embodiment is provided with an opening 102 to expose at least a portion of the electrical connection terminal 601.

[0088] The side wall 12 of the base 1 in this embodiment is provided with a decorative member 13, which is made of an opaque material.
