Description

A lighting fixture Technical Field

[0001] The present invention relates to the technical field of lighting fixtures, and in particular to a lighting fixture. Background Art

[0002] Lighting fixtures are common in daily life, including incandescent lamps, chandeliers, and linear high bay lights. During operation, the light-emitting components of lighting fixtures generate heat. As lighting fixtures operate longer, the accumulated heat increases, adversely affecting their lifespan and performance, and potentially creating safety hazards.

[0003] One existing method for dissipating heat from lighting fixtures is to increase the fixture's heat dissipation surface area, for example by increasing the surface area of ​​the housing connected to the light-emitting element. However, the further the housing is from the light-emitting element, the less effective the heat dissipation. To meet the lighting fixture's heat dissipation requirements, the fixture requires a sufficiently large heat dissipation surface area. This also results in a bulky fixture, making packaging, transportation, and installation difficult, and increasing the cost of the fixture.

[0004] The light-emitting surface and backlight surface of traditional lighting fixtures are isolated from each other, and heat is dissipated independently on both sides, which to a certain extent reduces the heat dissipation performance of the lighting fixture. How to design the heat dissipation structure of the lighting fixture while taking into account the heat dissipation of the light-emitting surface and backlight surface of the lighting fixture is a problem that needs to be solved urgently.

DETAILED DESCRIPTION

[0080] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concepts of the example embodiments to those skilled in the art. Identical reference numerals in the drawings represent identical or similar structures, and thus repeated descriptions thereof will be omitted.

[0081] The words expressing positions and directions described in the present invention are all explained with reference to the accompanying drawings as examples, but can be modified as needed, and all such modifications are within the scope of protection of the present invention.

[0082] As shown in FIG. 2 and FIG. 4 , a lighting fixture according to an embodiment of the present invention includes a housing 100 , which includes at least one mounting portion 1 , at least one connecting portion 9 , at least one heat dissipation channel 2 and at least one heat dissipation portion 3 .

[0083] With further reference to FIG. 1 , the mounting portion 1 is used to connect the light-emitting element 4 in the lighting fixture. To facilitate the installation of the light-emitting element 4, the mounting portion 1 may be provided with a cavity for accommodating the light-emitting element 4, wherein a plurality of positioning posts are provided within the cavity. The light-emitting element 4 may be pre-equipped with positioning holes that can be matched with the positioning posts. When the light-emitting element 4 is disposed within the cavity, the plurality of positioning posts can be matched with the positioning holes pre-equipped with the light-emitting element 4 to achieve positioning of the light-emitting element 4. If the light-emitting element 4 is not pre-equipped with positioning holes that can be matched with the positioning posts, when the light-emitting element 4 is disposed within the cavity, the plurality of positioning posts may also abut against the outer wall of the light-emitting element 4, i.e., the positioning posts are spatially arranged at the outer periphery of the contour of the light-emitting element 4, so that the plurality of positioning posts can limit the light-emitting element 4 in a manner similar to an interference fit, thereby achieving positioning of the light-emitting element 4. When the light-emitting element 4 is connected to the mounting portion 1, the mounting portion 1 can absorb or conduct at least part of the heat generated by the light-emitting element 4 during operation through heat transfer. The mounting portion 1 can be provided as one or more, for example, the mounting portion 1 can be provided as a pair, so that the housing 100 can be connected to two light-emitting elements 4, and at least part of the light-emitting element is accommodated in the cavity of the mounting portion.

[0084] The light-emitting element 4 may specifically include a lamp board 41 and light-emitting bodies 42. The lamp board 41 may be connected to a power source, and a conductive circuit is formed on the lamp board 41, and the light-emitting bodies 42 are electrically connected to the conductive circuit so that the power source can supply power to the light-emitting bodies 42 through the conductive circuit. The number of light-emitting bodies 42 may be set to multiple, and in order to make the light emitted by the light-emitting element 4 uniform, the multiple light-emitting bodies 42 are evenly spaced on the lamp board 41. For example, when at least a portion of the multiple light-emitting bodies 42 are distributed in a rectangular area, the portion of the light-emitting bodies 42 may be distributed in a rectangular array; the spacing between any two adjacent light-emitting bodies 42 along the length direction of the rectangle is the same, or the spacing between any two adjacent light-emitting bodies 42 along the width direction of the rectangle is the same, or in order to further improve the uniformity of the light emitted by the light-emitting element 4, the spacing between any two adjacent light-emitting bodies 42 along the length direction of the rectangle is the same as the spacing between any two adjacent light-emitting bodies 42 along the width direction of the rectangle. When at least a portion of the multiple light-emitting bodies 42 are distributed in a circular area, the portion of the light-emitting bodies 42 can be distributed in a circular array along the center of the circle; the spacing between any two adjacent light-emitting bodies 42 along the circumferential direction is the same, or the spacing between any two adjacent light-emitting bodies 42 along the radius of the circle is the same, or the spacing between any two adjacent light-emitting bodies 42 along the circumferential direction is the same as the spacing between any two adjacent light-emitting bodies 42 along the radius of the circle. The multiple light-emitting bodies 42 in a light-emitting element 4 can all be distributed in an array within a rectangular area or an annular area, or some of the light-emitting bodies 42 can be distributed in an array along one rectangular area or annular area, and some can be distributed in an array along another rectangular area or annular area. The light-emitting bodies 42 are preferably lamp beads or LED chips.

[0085] Of course, in some embodiments, in order to achieve a specific lighting effect, the light-emitting bodies 42 may also be unevenly distributed on the light board 41, that is, there is at least a partial area where the number of light-emitting bodies 42 per unit area is greater than / less than the number of light-emitting bodies 42 per unit area in another partial area; it can also be said that there is at least one area where the distribution density of light-emitting bodies 42 is greater than the distribution density of light-emitting bodies 42 in at least another area.

[0086] The heat dissipation channel 2 is provided on at least one side of the mounting portion 1 (or the housing 100), and air can flow within the heat dissipation channel 2. At least a portion of the air flowing within the heat dissipation channel 2 can flow through the mounting portion 1 to dissipate heat from the mounting portion 1. This allows at least a portion of the mounting portion 1 to maintain a lower temperature than the light-emitting element 4 when the light-emitting element 4 is in operation, and to continuously absorb or conduct heat generated by the light-emitting element 4.

[0087] In one embodiment of the present invention, the heat dissipation channel 2 at least partially penetrates the shell 100. In the direction perpendicular to the mounting portion 1 or parallel to the light emitting direction of the lighting fixture, at least a partial area of ​​the shell 100 is completely transparent and unobstructed, that is, the heat dissipation channel 2 completely penetrates at least a portion of the shell 100, or completely penetrates at least a portion of the lighting fixture, so that the heat dissipation channel 2 can better meet the gas convection requirements.

[0088] The light-emitting element 4 in the lighting fixture is generally arranged close to the light-emitting surface of the lighting fixture so that the light generated by the light-emitting element 4 can be transmitted to the outside as much as possible; therefore, most of the heat generated by the light-emitting element 4 during operation is concentrated near the light-emitting surface of the lighting fixture. In the design of the lighting fixture, the conventional design is that when the lighting fixture is in the working state, its lighting fixture body (also known as the shell) is covered with the light-emitting element, and relative to the light-emitting element, the lighting fixture body is arranged on the light-emitting element in an upside-down manner. The heat generated by the light-emitting element when working will be constrained and accumulated to a certain extent by the lighting fixture body. In order to effectively dissipate heat from the lighting fixture, the heat dissipation channel 2 can specifically extend from the light-emitting surface of the lighting fixture to the backlight surface of the lighting fixture, so that at least part of the gas in the heat dissipation channel 2 can flow from the light-emitting surface of the lighting fixture to the backlight surface of the lighting fixture, so as to take the heat at the light-emitting surface of the lighting fixture away and flow to the backlight surface of the lighting fixture where the temperature is lower, and finally dissipate the heat outside the lighting fixture to improve the heat dissipation efficiency of the lighting fixture.

[0089] The formation of gas flow in the heat dissipation channel 2 can be formed by the exchange of hot and cold air. Specifically, when the light-emitting element 4 is in operation, the temperature of its surroundings will rise, that is, the air near the light-emitting element 4 will become hot air. The hot air will rise because of the increase in volume and decrease in density. The lighting fixture is usually set at a high place such as the ceiling, and the light-emitting surface of the lighting fixture faces downward, that is, the backlight surface of the lighting fixture is higher than its light-emitting surface. If the air on the light-emitting surface of the light-emitting element 4 rises, it will move to the backlight surface of the lighting fixture and continue to be emitted outward at the backlight surface of the lighting fixture; while the air on the light-emitting surface of the light-emitting element 4 will quickly be emitted from the back of the lighting fixture along the heat dissipation channel 2. Then, near the light-emitting element 4, that is, at least part of the area near the light-emitting surface, a relatively thin air area will be formed, that is, a low-pressure area will be formed. The relatively low-temperature air in the environment will naturally fill in the vicinity of the light-emitting element 4, absorb the heat generated by the light-emitting element 4 and continue to be emitted from the heat dissipation channel 2, thereby forming a complete air circulation.

[0090] The heat dissipation channel 2 is preferably provided on the long side of the mounting portion 1, while the heat dissipation channel 2 may not be provided on the short side of the mounting portion 1, so as to improve the heat dissipation performance of the lighting fixture while reducing the volume of the lighting fixture housing 100. The reason for this is that the provision of the heat dissipation channel 2 will inevitably require the housing 100 to extend a portion of the structure outward along the side of the mounting portion 1 where the heat dissipation channel 2 is provided, in order to form the heat dissipation channel 2, which will increase the volume of the housing 100, that is, the overall volume of the lighting fixture. However, providing the heat dissipation channel 2 only on the long side of the mounting portion 1 allows the length of the heat dissipation channel 2 along the length direction of the housing to be approximately the same as the length of the long side of the mounting portion 1, that is, the length of the heat dissipation channel 2 is longer, and the heat dissipation channel 2 matches the distribution of the light-emitting body 42 along the length direction of the mounting portion. Along the length direction, each light-emitting body 42 has a heat dissipation channel 2 around it, and the overall arrangement width of the light-emitting body 42 along the width direction is smaller. The light-emitting body 42 located in the middle of the width direction can also enjoy the heat dissipation effect of the heat dissipation channel 2, and the overall heat dissipation effect is also better, and the heat dissipation benefit is high. Furthermore, if the heat dissipation channel 2 is provided on the short side of the heat dissipation channel 2, its heat dissipation effect is poorer than that of the heat dissipation channel 2 on the long side of the mounting portion 1. The light-emitting elements 42 are distributed much more in the length direction than in the width (short side) direction. If the heat dissipation channel 2 is provided along the width (short side), only the light-emitting elements 42 located near the short side can be cooled by the heat dissipation channel 2. Furthermore, since the long side is originally larger than the short side, the light-emitting elements 42 corrected along the long side cannot be cooled by the heat dissipation channel provided along the short side, resulting in low heat dissipation efficiency and increasing the volume of the lighting fixture housing 100. Furthermore, the heat dissipation channel 2 provided along the long side can also cool the light-emitting elements 42 located near the short side. Therefore, providing the heat dissipation channel 2 only on the long side of the mounting portion 1 can effectively improve the heat dissipation performance of the lighting fixture and reduce the volume of the lighting fixture (or housing 100). In other words, while meeting the heat dissipation requirements, the added volume of the lighting fixture (or housing 100) can be minimized. It should be pointed out that, as needed, the lighting fixture may also be provided with a heat dissipation channel 2 on the short side of the mounting portion 1 in order to further improve its heat dissipation performance.

[0091] The mounting portion 1 may specifically include a pair of opposed long sides. The housing 100 may be provided with a heat dissipation channel 2 on only one long side of the mounting portion 1, or may be provided with a heat dissipation channel 2 on one side of each long side of the mounting portion 1. Preferably, to improve the heat dissipation effect and balance the heat dissipation effect on both sides of the mounting portion 1, a heat dissipation channel 2 is provided on both long sides of the mounting portion 1.

[0092] Referring further to Figure 2 , the heat dissipation portion 3 is connected to the mounting portion 1 and is capable of absorbing or conducting at least some of the heat from the mounting portion 1. This allows the heat dissipation portion 3 to absorb or conduct at least some of the heat generated by the light-emitting element 4 through the mounting portion 1. Furthermore, the provision of the heat dissipation portion 3 effectively increases the heat dissipation area of ​​the lighting fixture housing 100. At least a portion of the heat dissipation portion 3 is located within the heat dissipation channel 2, allowing at least some of the airflow within the heat dissipation channel 2 to flow through the heat dissipation portion 3, thereby dissipating heat from the heat dissipation portion 3.

[0093] The heat dissipation portion 3 is disposed on the side of the mounting portion 1 facing away from the light-emitting element 4, that is, the heat dissipation portion 3 and the light-emitting element 4 are disposed on opposite sides of the mounting portion 1. Alternatively, the heat dissipation portion 3 is disposed on the backlight side of the mounting portion 1, and the light-emitting element is disposed on the light-emitting side of the mounting portion 1, so as to prevent the heat dissipation portion 3 from blocking the light generated by the light-emitting element 4. The heat dissipation portion 3 may specifically include a plurality of heat dissipation fins 31, which are spaced apart from each other along the length direction of the mounting portion 1. The thickness direction of the heat dissipation fins 31 is parallel to the length direction of the mounting portion 1, that is, the heat dissipation fins 31 are approximately perpendicular to the plane of the mounting portion 1 and parallel to the short side of the mounting portion 1. Preferably, the plurality of heat dissipation fins 31 are arranged at equal intervals so that the heat dissipation portion 3 composed of the plurality of heat dissipation fins 31 uniformly absorbs or conducts heat from various parts of the mounting portion 1. For lighting fixtures with different heat dissipation requirements, the number and height of the heat dissipation fins 31 can be adjusted accordingly; for example, when the heat dissipation requirement is higher, the number of heat dissipation fins 31 can be increased, and / or the height of the heat dissipation fins 31 can be increased; when the heat dissipation requirement is lower, the number of heat dissipation fins 31 can be reduced, and / or the height of the heat dissipation fins 31 can be lowered.

[0094] In another embodiment of the present invention, the thickness direction of the heat dissipation fins 31 is perpendicular to the length direction of the mounting portion 1 , that is, the heat dissipation fins 31 are arranged along the length direction of the mounting portion 1 (or the power supply assembly).

[0095] In one embodiment of the present invention, the heat dissipation fins 31 (also referred to as the heat dissipation portion 3 ) are integrally formed with the mounting portion 1 , or in other words, integrally formed with the housing 100 .

[0096] In one embodiment of the present invention, the heat dissipation fins 31 (also known as the heat dissipation portion 3 ) are formed separately and then mounted on the mounting portion 1 , or in other words, the heat dissipation fins 31 are formed separately and then assembled with the housing 100 .

[0097] The connecting portion 9 is used to install a power supply assembly (not shown) that can supply power to the light-emitting element 4, that is, the mounting portion 9 is provided with a corresponding accommodation space, and at least a portion of the power supply assembly is provided in the accommodation space. When there is only one mounting portion 1, the connecting portion 9 can be provided on one side of the mounting portion 1. When there are at least two mounting portions 1, for example, two in one embodiment, the connecting portion 9 can be provided between the two mounting portions 1, that is, the two mounting portions 1 are respectively provided on both sides of the connecting portion 9, so that the power supply assembly installed on the connecting portion 9 can simply and conveniently supply power to a pair of light-emitting elements 4 connected to the two mounting portions 1. The mounting portion 1 and the connecting portion 9 can be integrally formed from the same material, or they can be independently formed and then assembled.

[0098] In one embodiment, the heat dissipation channel 2 is provided between the mounting portion 1 and the connecting portion 9 , and can simultaneously dissipate heat from the connecting portion 9 and the mounting portion 1 located on both sides of the heat dissipation channel 2 .

[0099] In order to further improve the heat dissipation performance of the lighting fixture, the housing 100 of the lighting fixture is made using a die-casting process. Die-cast parts usually have a larger surface area, which can increase the heat dissipation area of ​​the lighting fixture housing 100; and, die-casting can reduce the pores and bubbles inside the parts, improve the heat conduction efficiency of the parts, and improve the heat dissipation performance of the housing 100. The mounting portion 1, the connecting portion 9, the heat dissipation channel 2 and the heat dissipation portion 3 are preferably an integrated structure, so that the housing 100 can be formed using an integrated die-casting process. There is no gap between the parts, that is, the heat conduction between the parts is not blocked, so that the heat generated by the heat-generating components of the lighting fixture when it is working can be quickly conducted to the non-heated position, further improving the heat dissipation performance. As shown in Figures 1 and 2, the present invention also provides a lighting fixture, including the above-mentioned housing 100, at least one light-emitting element 4 for generating a light source, a power supply component, a junction box 7, and a lampshade 5.

[0100] The setting of the housing 100 reduces the volume of the lighting fixture, thereby enabling the lighting fixture to have a higher lumen-to-area ratio. For example, the lumen of the lighting fixture of the present invention can be controlled within a range of 30,000Lm to 36,000Lm; its luminous area is 80.6mm*355.6mm, i.e. 0.02866136m 2 Therefore, the lumen-to-area ratio of the lighting fixture of the present invention can be 1046705.39Lm / m 2 ~1256046.47Lm / m 2 In some other embodiments of the present invention, the lumen-to-area ratio of the lighting fixture can be set to be greater than 1,000,000 Lm / m 2 .

[0101] The light-emitting elements 4 are mounted on the mounting portion 1, and the number of the light-emitting elements 4 is the same as the number of the mounting portions 1, and they correspond one to one. When multiple mounting portions 1 are provided, the mounting portions 1 are spaced apart from each other in the horizontal direction and do not overlap with the connecting portion 9 (or the power supply assembly) in the vertical direction. In other words, the vertical overlapping area of ​​the mounting portions 1 is zero. The light-emitting elements 4 are disposed in the mounting portion 1. The light-emitting elements 4 are one of the main heat-generating components when the lighting fixture is in operation. The power supply assembly is also one of the heat-generating components when the lighting fixture is in operation. Spacing the heat-generating components apart or not overlapping can effectively avoid heat accumulation (or heat concentration) that reduces the light output effect of the lighting fixture.

[0102] With further reference to FIG3 , the power supply assembly is mounted on the connection portion 9 of the housing 100. The power supply assembly needs to be connected to an external device, so the power supply assembly is connected to a plurality of wires. In order to facilitate the outlet of the plurality of wires, the power supply assembly is connected to a junction box 7. The junction box 7 is provided with a chamber that can accommodate the wires, and at least two surfaces of the junction box 7 are provided with wire outlet holes 71, and the wires located inside the junction box 7 can extend from the wire outlet holes 71 to the outside. The wire outlet holes 71 are preferably provided on the top wall and one side wall of the junction box 7, so that the wires can extend in the vertical direction through the wire outlet holes 71 on the top wall of the junction box 7, or extend in the horizontal direction through the wire outlet holes 71 on the side wall of the junction box 7, making the outlet of the wires more convenient and flexible.

[0103] The junction box 7 is also provided with a connecting ear 72, which is located on the side of the junction box 7 facing the power supply assembly. The junction box 7 can be connected to the connecting portion 9 on which the power supply assembly is mounted via the connecting ear 72. Specifically, the connecting ear 72 can be provided with a through hole, and the connecting portion 9 can be provided with a threaded hole that can communicate with the through hole of the connecting ear 72. A screw is provided through the through hole and the threaded hole in sequence to screw the connecting portion 9 together and achieve a fixed connection between the connecting ear 72 and the connecting portion 9. The provision of the connecting ear 72 allows the junction box 7 and the connecting portion 9 to be fixed with only a single screw, simplifying the connection process between the junction box 7 and the connecting portion 9.

[0104] Referring to Figures 1 and 5, a lampshade 5 is provided on the light-emitting surface of the lighting fixture. The lampshade 5 completely covers the light-emitting element 4 and can process the light emitted by the light-emitting element 4 before emitting it. The lampshade 5 is connected to the mounting portion 1 of the housing 100. The lampshade 5 and the mounting portion 1 together form a receiving cavity 11. The light-emitting element 4 is disposed within the receiving cavity 11 so that the lampshade 5 can cover the light-emitting element 4 connected to the mounting portion 1. In order to allow the light from the light-emitting element 4 to transmit to the outside through the lampshade 5, the lampshade 5 is made of a translucent material. For example, the lampshade 5 is made of transparent plastic, acrylic, textile, glass, PC, etc. When the light emitted by the light-emitting unit 4 is optically coupled to the lampshade 5, at least one of the following phenomena will occur: light diffusion, transmission, refraction, diffraction, etc., that is, the lampshade 5 has at least one of the following functions: light diffusion, transmission, refraction, diffraction, etc. The lampshade 5 can adopt a common rectangular plate structure; in some embodiments, in order to adjust the light pattern of the light emitted by the lighting fixture, the lampshade 5 is adjusted to an arc shape or a shape with a specific curved surface, so that the light emitted by the light-emitting unit 4 undergoes light diffusion, transmission, refraction, diffraction and the like at different positions, thereby obtaining different light patterns. In one embodiment of the present invention, the lampshade 5 and the mounting portion 1 can be connected by screws. Specifically, the lampshade 5 is provided with a screw hole, and the mounting portion 1 is provided with a threaded hole that matches the screw hole. The lampshade 5 is pressed against the mounting portion 1 by a screw that passes through the screw hole and is threadedly connected to the threaded hole, thereby achieving a fixed connection between the lampshade 5 and the mounting portion 1.

[0105] In another embodiment of the present invention, the lampshade 5 and the mounting part 1 can also be fixedly connected by multiple fixing units 6. The lampshade 5 does not need to be provided with screw holes, so that the lampshade 5 and the mounting part 1 jointly form a accommodating cavity 11 as a sealed cavity, which can prevent water vapor from entering the accommodating cavity 11 and damaging the light-emitting element 4.

[0106] Specifically, a portion of the fixing unit 6 is connected to the mounting portion 1, and another portion is connected to the lampshade 5, so that the lampshade 5 is connected to the mounting portion 1. At least part of the fixing unit 6 is distributed on opposite sides of the lampshade 5 to fix the opposite sides of the lampshade 5.

[0107] With further reference to Figures 5 to 7 , the fixing unit 6 specifically includes a fixing portion 61 and a fixing member 62. The fixing portion 61 is connected to the mounting portion 1 and is preferably integrally formed with the mounting portion 1. When the lighting fixture housing 100 is formed using an integral die-casting process, the fixing portion 61 can be molded together with the lighting fixture housing 100. The fixing portion 61 defines a fixing groove 611 for mating with the fixing member 62.

[0108] The fixing member 62 includes a first connecting portion 621 and a second connecting portion 622 that are interconnected. The first connecting portion 621 and the second connecting portion 622 are preferably an integral structure, that is, the fixing member 62 is formed by integrally stamping a material, and one end of the fixing member 62 is bent to form the second connecting portion. The first connecting portion 621 and the second connecting portion 622 are approximately perpendicular to each other. The first connecting portion 621 is perpendicular to the light-emitting surface of the lighting fixture and is inserted into the interior of the lighting fixture. The second connecting portion 622 is parallel to the light-emitting surface of the lighting fixture and is pressed against the light-emitting surface of the lighting fixture to fix the lampshade 5. At least a portion of the first connecting portion 621 is accommodated in the fixing groove 611, and the first connecting portion 621 is interference-fitted with the fixing portion 61 formed with the fixing groove 611, so that the fixing member 62 can be fixed to the fixing portion 61. The first connecting portion 621 can specifically include a first side wall 6211 and a second side wall 6212 that are interconnected. The first side wall 6211 is inclined relative to the second side wall 6212, and can rotate toward the second side wall 6212 when squeezed, thereby storing elastic potential energy. In the relaxed state, the maximum distance between the side of the first side wall 6211 facing away from the second side wall 6212 and the side of the second side wall 6212 facing away from the first side wall 6211 is greater than the width of the fixing groove 611. In other words, the maximum distance from the farthest end of the first side wall 6211 to the surface of the second side wall 6212 (the surface of the second side wall 6212 used to fix the first side wall 6211) is greater than the width of the fixing groove 611. When the fixing piece 62 is installed on the fixing portion 61, the second side wall 6212 and the first side wall 6211 abut against a pair of opposite side walls of the fixing groove 611, and the first side wall 6211 is squeezed and rotated toward the second side wall 6212, so that the first side wall 6211 is away from the side of the second side wall 6212, and the maximum distance between the first side wall 6211 and the side of the second side wall 6212 away from the first side wall 6211 is equal to the width of the fixing groove 611, that is, the farthest end of the first side wall 6211, the maximum distance to the surface of the second side wall 6212 (the surface refers to the surface of the second side wall 6212 used to fix the first side wall 6211) is equal to the width of the fixing groove 611. At this time, the first side wall 6211 stores elastic potential energy, and the fixing piece 62 is interference fit with the fixing portion 61, so that the fixing piece 62 is fixed to the fixing portion 61.

[0109] At least a portion of the second connecting portion 622 abuts against the outer end surface of the lampshade 5, and by controlling the length of the first connecting portion 621 extending into the fixing groove 611 to adjust the position of the second connecting portion 622, the second connecting portion 622 can be made to press the lampshade 5 against the mounting portion 1, thereby achieving a fixed connection between the lampshade 5 and the mounting portion 1.

[0110] In other embodiments of the present invention, the lampshade 5 can also be fixed by glue or snap fasteners.

[0111] In another embodiment of the present invention, a micro-array optical structure is provided on the surface of the lampshade 5, such as a micro-structure array of protrusions, depressions or inclined surfaces, so that the lampshade has different light emitting effects.

[0112] Referring to FIG8 , which is a schematic diagram of the overall front structure of a lighting fixture in another embodiment of the present invention, as shown in FIG8 , the lighting fixture also includes a housing 100. The housing 100 is generally rectangular in shape when viewed from above. A connecting portion 9 extending parallel to the longitudinal direction of the rectangle is provided along the length of the rectangle. Mounting portions 1 are provided on both sides of the connecting portion 9 along the width direction. The mounting portion 1 can be used to mount a light-emitting element 4 and a heat sink 3. The light-emitting element 4 and the heat sink 3 are provided on different surfaces of the mounting portion 1. Alternatively, the light-emitting element 4 and the heat sink 3 are provided on opposite surfaces of the mounting portion 1, i.e., the two are stacked in the light-emitting direction. When the lighting fixture is actually in use, the heat sink 3 is located above the light-emitting element 4, so that the heat generated by the light-emitting element 4 during operation can be better dissipated to the heat sink 3. In one embodiment of the present invention, at least one heat sink 31 is provided on the heat sink 3. The heat sink 31 extends along the length of the lighting fixture. The lighting fixture includes a plurality of heat sink fins 31, which are arranged at a certain distance from each other. The heat dissipation fin 31 has a flat surface, and a strip-shaped gas flow channel extending along the length direction of the lighting fixture is formed between the two heat dissipation fins 31. Preferably, the surface of the heat dissipation fin 31 is a smooth and flat surface, so that the inside of the formed gas flow channel is smooth and flat, and does not affect the gas flow channel.

[0113] In one embodiment of the present invention, a plurality of heat dissipation slots 91 are provided on the two side walls of the connecting portion 9 facing the heat dissipation portion 3. The heat dissipation slots 91 penetrate the side walls of the connecting portion 9, thereby connecting the interior and exterior of the connecting portion 9 and achieving rapid gas exchange (gas flow). In some embodiments, the interior of the connecting portion 9 has a space for accommodating a power supply assembly (not shown). The power supply assembly is also one of the main heat-generating components in the lighting fixture and will also face heat dissipation issues in actual operation. The heat dissipation slots 91 provided on the side walls of the connecting portion 9 can effectively dissipate heat from the power supply, thereby maintaining efficient and stable operation of the lighting fixture.

[0114] Referring to FIG9 , which is a schematic diagram of an exploded view of a lighting fixture in an embodiment of the present invention (front view), and in conjunction with FIG10 , the housing 100 includes at least two mounting portions 1 and a connecting portion 9. The mounting portion 1 serves as a mounting body, and the connecting portion 9 is disposed between the two mounting portions 1. The connecting portion 9 protrudes upward to form an internal space in which a power supply assembly can be disposed. The mounting portion 1 includes a light source mounting portion 10. The two light source mounting portions 10 are disposed on both sides of the connecting portion 9, respectively. The light source mounting portion 10 is provided with a plurality of hollow grooves 12, which are used to expose the light source so that light can pass through. On the back side of the light source mounting portion 10, that is, in the light emitting direction away from the lighting fixture 100, light-emitting elements 4 are stacked, wherein the light-emitting elements 4 include a lamp board 41 and a light-emitting body 42 disposed on the lamp board 41. The light-emitting body 42 is disposed on the surface of the lamp board 41 close to the light source mounting portion 10, and the light emitted by the light-emitting body 42 can pass through the hollow grooves 12.

[0115] In one embodiment of the present invention, the light source 42 is an LED chip array. Multiple LED chip arrays are mounted on the light board 41, each corresponding to a corresponding hollow slot 12. Light emitted by the LED chip array can pass through the hollow slot 12, and the number of hollow slots 12 is greater than or equal to the number of LED chip arrays. A heat sink 3 is stacked on the surface of the light-emitting element 4 facing away from the light source mounting portion 10. Heat generated by the light-emitting element 4 during operation is rapidly conducted to the outside through the heat sink 3 and dissipated.

[0116] In the light emitting direction of the light source mounting part 10 (or the mounting part 1), a lampshade 5 is provided. The lampshade 5 is provided on the light source mounting part 10 (or the mounting part 1) and completely covers the light emitting body 42. The light emitted by the light emitting body 42 is subjected to light processing and finally emitted from the lighting fixture.

[0117] The lampshade 5, mounting portion 1, light-emitting element 4, and heat sink 3 are stacked in sequence, opposite the direction of light emission from the lighting fixture. A certain gap is provided between the light-emitting element 4 and the lampshade 5, creating a gas space to facilitate heat dissipation. End caps 54 are provided at both ends of the length of the lampshade 5, mounting portion 1, light-emitting element 4, and heat sink 3. These end caps 54 encapsulate the aforementioned components and mechanically support or abut against each other, thereby improving the overall reliability of the lighting fixture. (The aforementioned components may also be secured by adhesive, screws, snap-fit ​​fasteners, magnets, or welding).

[0118] The light source mounting portion 10 and the connecting portion 9 are connected by a bending portion 92. In another embodiment, the light source mounting portion 10 and the connecting portion 9 are integrally formed on the same plate, for example, by stamping. The height of the light source mounting portion 10 (or the heat dissipation portion 3) is less than the height of the connecting portion 9, that is, the light source mounting portion 10 (or the heat dissipation portion 3) on both sides of the connecting portion 9 does not hinder the heat dissipation of the connecting portion 9, that is, there is a height difference between the connecting portion 9 and the light source mounting portion 10 (or the heat dissipation portion 3) along the light emitting direction of the lighting fixture. The lampshade 5 includes an air vent 51 and at least one light processing element. The light processing element includes a first optical component 52 and a second optical component 53, wherein the first optical component 52 and the second optical component 53 can be integrally formed or separately formed. The first optical component 52 is a light-transmitting material and is provided on one side of the light source mounting portion 10 along the light emitting direction of the lighting fixture. The second optical component 53 is provided on one side of the connecting portion 9 along the light emitting direction of the lighting fixture, wherein the second optical component 53 can be made of a light-transmitting material or an opaque material. The first optical member 52 and the second optical member 53 can be made of materials such as plastic, resin, glass, etc., or a combination thereof.

[0119] Between the first optical component 52 and the second optical component 53, a plurality of air holes 51 are provided along the length direction thereof. The positions of the air holes correspond to the bending portion 92. Corresponding air holes (not shown) may also be provided on the bending portion 92, so that the lighting fixture also has a through air flow channel along the light-emitting direction, so that the air flow can directly convect from the light-emitting surface side of the lighting fixture to the back side of the lighting fixture, that is, the other side away from the light-emitting direction, and dissipate into the external environment, thereby quickly taking away the heat generated when the lighting fixture is working.

[0120] In one embodiment of the present invention, the first optical component 52 is arranged on both sides of the second optical component 53, or in other words, the first optical component 52 is arranged on the outside of the second optical component 53, that is, the first optical component 52 is arranged below the light source mounting portion 10 (that is, along the light emitting direction of the lighting fixture, away from the light emitting direction is below), the second optical component 53 is arranged below the connecting portion 9, and the first optical component 52 and the second optical component 53 are formed as one piece.

[0121] Refer to Figure 10, which is a schematic diagram of the light-emitting element 4 in one embodiment of the present invention, wherein the light-emitting element 4 includes a lamp board 41 and a plurality of light-emitting bodies 42 arranged on the lamp board 41, and a circuit structure is provided on the lamp board 41 to conduct the light-emitting bodies 42, and the light-emitting bodies 42 are illuminated by powering the lighting fixture, wherein the light-emitting bodies 42 can be an LED chip array (or LED lamp bead array), which are arranged at equal intervals or unequal intervals.

[0122] Referring to Figures 9, 10, 11, 12A, and 12B, Figure 11 is a cross-sectional view of a lighting fixture along the width direction in one embodiment of the present invention, Figure 12A is a schematic diagram of the back of the lighting fixture after some components are hidden, and Figure 12B is a schematic diagram of the installation positions of the light source mounting portion, light-emitting elements, and heat dissipation portion in one embodiment. As shown in Figures 9, 11, and 12B, the light-emitting elements 4 are stacked on the light source mounting portion 10. The surface of the light source mounting portion 10 on which the light-emitting elements 4 are mounted can be a flat surface or a groove-shaped surface with a lower center and higher sides. When the groove-shaped surface is provided, the light-emitting elements 4 are at least partially accommodated in the groove of the groove-shaped surface, and at least partially the heat dissipation portion 3 is accommodated in the groove structure of the groove-shaped surface. In one embodiment, the surface of the lamp panel 41 in the light-emitting element 4 that faces the lampshade 5 (or the surface along the light-emitting direction) is bonded to the surface of the light source mounting portion 10, and the surface of the lamp panel 41 that faces away from the light-emitting direction is bonded to the surface of the heat dissipation portion 3. In other words, the lamp panel 41 has a first surface and a second surface that are opposite each other, with a plurality of light-emitting bodies 42 disposed on the first surface, the light source mounting portion 10 being bonded to the first surface, and the heat dissipation portion 3 being bonded to the second surface. The material of the light source mounting portion 10 and the heat dissipation portion 3 can be a metal material with fast thermal conductivity and heat dissipation, so as to quickly conduct and dissipate the heat generated by the light-emitting element 4 during operation.

[0123] In one embodiment of the present invention, the lamp board 41 and the first optical component 52 are spaced a certain distance apart from each other, and a cavity is formed between the two along their length direction for heat dissipation; the lamp board 41 and the surface of the heat dissipation part 3 can also be spaced a certain distance apart to form a cavity for heat dissipation; air flows through the cavity.

[0124] 12A , the light source mounting portion 10 has a plurality of hollow grooves 12. The hollow grooves 12 are arranged along the width of the light source mounting portion 10 and are parallel to each other. The light emitters 42 are positioned corresponding to the hollow grooves 12 and are exposed through the hollow grooves 12. The light emitted by the light emitters 42 can pass through the hollow grooves 12 and directly emit to the first optical member 52. Of course, in some embodiments, the hollow grooves 12 can also be non-parallel, that is, there is an angle between the hollow grooves 12.

[0125] Refer to Figure 13, which is a top view of the lighting fixture in one embodiment of the present invention. Between the connecting portion 9 and the light source mounting portion 10, there is also a heat dissipation channel 2 that runs through the upper and lower parts. The heat dissipation channel 2 is formed at the bending portion 92 and is combined with the air vent 51 to achieve vertical penetration, that is, the heat dissipation channel 2 is roughly perpendicular to the lampshade 5, or the heat dissipation channel 2 extends along the light emitting direction of the lighting fixture or away from the light emitting direction, and runs through the lighting fixture, so that the gas on the light emitting surface side of the lighting fixture can directly form gas exchange with the gas on the back side of the lighting fixture (the side away from the light emitting surface) through the heat dissipation channel 2.

[0126] In one embodiment of the present invention, the connecting portion 9 has two surfaces that are approximately perpendicular to the lampshade 5 , or in other words, side walls of the connecting portion 9 . Heat dissipation grooves 91 may be further provided on the side walls of the connecting portion 9 .

[0127] In one embodiment of the present invention, the light source mounting portion 10 in the mounting portion 1 can rotate relative to the connecting portion 9, that is, the light output angle of the lighting fixture can change with the rotation of the light source mounting portion, that is, the light output angle of the lighting fixture can be adjusted according to needs.

[0128] Referring to FIG14 , which is a schematic diagram of the entirety of a lighting fixture in another embodiment of the present invention, the lighting fixture includes a connecting portion 9 and a light source mounting portion 10 movably connected to both sides of the connecting portion 9. A heat dissipation portion 3 is provided on the light source mounting portion 10. The heat dissipation portion 3 includes a plurality of heat dissipation fins 31 (not shown) extending along the length of the lighting fixture. The maximum surface (heat dissipation surface) of the heat dissipation fins 31 is approximately perpendicular to the light emitting surface of the lighting fixture (the light emitting surface can be a horizontal plane in the light emitting direction of the lighting fixture, or in the present invention, the lampshade 5). The heat dissipation surfaces of the heat dissipation fins 31 are parallel to each other and form an air flow path along the length of the lighting fixture, i.e., approximately parallel to the lampshade 5. A plurality of ventilation windows 13 are provided on the sidewalls of the light source mounting portion 10. These ventilation windows 13 allow air to flow along the width of the lighting fixture, i.e., some of the air in the air flow path of the heat dissipation portion 3 is exchanged with the outside of the lighting fixture through the ventilation windows 13.

[0129] The sidewalls of the connecting portion 9 are provided with a plurality of heat dissipation slots 91, which connect the interior of the connecting portion 9 to the external environment and enable gas exchange. In this embodiment, the lighting fixture further includes an end cap 54, which includes a first end cap 540 and a second end cap 541, wherein the first end cap 540 is fixed to both ends of the connecting portion 9, and the second end cap 541 is fixed to both ends of the light source mounting portion 10. The first end cap 540 includes a rotational coupling area 5400 for connecting and fixing the second end cap 541, and the second end cap 541 is snap-fitted to the end of the light source mounting portion 10. The first end cap 540 then covers the side of the second end cap 541 away from the light source mounting portion 10, and the first end cap 540 covers at least a portion of the second end cap 541. The first end cap 540 and the second end cap 541 are connected by bolts, rivets, or other rotatable fixing structures.

[0130] Refer to Figure 15, which is a schematic diagram of the lampshade in this embodiment of the present invention, wherein the lampshade 5 includes a first optical component 52 and a second optical component 53. The first optical component 52 and the second optical component 53 are independent of each other and are spaced a certain distance apart. The first optical component 52 is fixed to the light source mounting portion 10, and the second optical component 53 is fixed to the connecting portion 9. There is a gap 55 between the light source mounting portion 10 and the connecting portion 9. The gap 55 can provide a heat dissipation channel, that is, the heat dissipation channel 2 is provided between the mounting portion 1 (or the light source mounting portion 10) and the connecting portion 9. In addition, the width of the gap 55 is greater than or equal to the thickness of the light source mounting portion 10. The light source mounting portion 10 can be rotated relative to the connecting portion 9, thereby preventing interference between the light source mounting portion 10 and the connecting portion 9 during rotation. The light source mounting portion 10 can rotate relative to the connecting portion 9, that is, the first optical member 52 and the second optical member 53 can rotate relative to each other. The relative positions and angles between the two can be various. For example, the relative angle between the first optical member 52 and the second optical member 53 can be -120° to 180°, such as 30°, 60°, or 90°. The first optical member 52 and the second optical member 53 can be independently formed and separated by a certain distance.

[0131] In some embodiments, the sidewall of the connecting portion 9 may also be in an inwardly contracted arc shape, such as an inwardly concave arc shape, so as to reduce the width of the gap 55 or even eliminate the gap 55 .

Of course, the spacing between the light-emitting bodies 42 can also be set according to needs, and the arrangement of the light-emitting bodies 42 can also be adjusted according to needs. For example, the spacing between the light-emitting bodies 42 is at least two types, and the light-emitting bodies 42 are arranged in an arc shape along the length direction of the lamp board 41, etc. Figures 10 and 21 are only distance descriptions and not limitations.

Figure 22B shows the shape at a negative 30-degree angle. In this shape, the light output of the light source mounting portion 10 is concentrated, which is suitable for use in scenarios that require high brightness but a small area. Figure 22C is a schematic diagram of the shape at a 60-degree angle. The light output of the light source mounting portion 10 is divergent, which is suitable for wide areas with low illumination. The shape shown in Figure 14 is suitable for general use scenarios, such as warehouses or aisles. Of course, the above angles are just examples, and the size of the angle can be adjusted according to actual needs.

The sidewalls and top surface (the top surface refers to the surface away from the mounting portion 1) of the connecting portion 9 are provided with a plurality of heat dissipation slots 91 and 91'. The heat dissipation slots 91' are provided on the top surface of the connecting portion 9, and a dust shield is provided above the heat dissipation slots 91', maintaining a certain distance from the heat dissipation slots 91'. In other words, the dust shield is provided above the heat dissipation slots 91' without enclosing them. While meeting the heat dissipation requirements, it can also block foreign matter from entering the interior of the connecting portion 9 and affecting the operation of the lighting fixture.

[0145] Referring to FIG24 , which is an enlarged schematic diagram of point B in FIG23 , as shown, each heat dissipation slot 91′ is covered with a dustproof canopy 910. The dustproof canopy 910 has a certain curvature and arches away from the heat dissipation slot 91′, forming an opening structure facing one side, that is, the opening faces the outside of the connecting portion 9. This ensures that when the hotter air inside the connecting portion 9 flows out, it will not cause airflow collision and heat accumulation due to the two openings being arranged opposite each other, thereby affecting the heat dissipation of the connecting portion 9. The dustproof canopy 910 can be integrally formed on the connecting portion 9 through a stamping process, or it can be formed separately and then fixed to the connecting portion 9 by methods such as gluing or welding.

The lampshade 5 includes a first optical component 52 and a second optical component 53. In some embodiments, the first optical component 52 and the second optical component 53 can be integrally formed from the same or different materials, or can be separately formed from the same or different materials. In some embodiments, a plurality of heat dissipation holes 530 arranged in a row are provided on the surface of the second optical component 53. The aperture of the heat dissipation holes 530 can be of multiple types, or in other words, the surface of the second optical component 53 is provided with heat dissipation holes 530 of at least two or more apertures.

A sensor accommodating hole 531 is also provided on the second optical component 53, and a sensor 532 is provided inside. The sensor 532 is at least partially arranged in the sensor accommodating hole 531.

The mounting portion 1 includes a second optical component 53 located in the middle, and two positioning plates 101 are respectively provided at both ends of the second optical component 53 along the length direction. The positioning plates 101 extend to the second optical component 53 toward the connecting portion 9, and the positioning plates 101 and the end caps 54 are provided with matching through holes for screw structures to pass through and fix the positioning plates 101 and the end caps 54, that is, the connecting portion 9 is directly stacked on the second optical component 53. When a heating element (such as When the power supply is turned on, the heat dissipation hole 530 on the second 53 can allow the space with lower external temperature to directly enter the interior of the connecting part 9. Because the heights of the heat dissipation grooves 91' and the heat dissipation grooves 91 on the connecting part 9 are higher than the height of the heat dissipation holes 530 (see Figure 25) when the lighting fixture is in normal use (that is, the light output direction is downward), and the air with higher temperature will rise, that is, the air in the connecting part 9 rises due to the heat, and after flowing out from the heat dissipation grooves 91' and the heat dissipation grooves 91, it will form convection with the external air through the heat dissipation holes 530 and thus form an effect similar to exhaust, that is, form directional air flow, thereby improving the heat dissipation performance.
