The utility model belongs to the technical field of LED lighting devices, and particularly relates to LED lighting equipment.

Background

LED lighting is widely used because of its energy saving, long life, etc. LED lamps and lanterns among the prior art, common include flat board lamp and grille lamp.

The flat lamp in the prior art generally comprises a lamp strip, a bottom frame, a light guide plate and a diffusion plate, wherein the lamp strip is arranged at the side part of the bottom frame so as to provide lateral light, and the light emitted by the lamp strip is emitted from the diffusion plate after passing through the light guide plate. The prior art flat lamp has the following disadvantages: after passing through the light guide plate and the diffusion plate, the light emitted by the light bar has larger light loss, so that the light emitting efficiency of the flat plate lamp is lower; the light guide plate has higher cost, is unfavorable for the cost control of the flat lamp, and has more common glare control.

The grille lamp in the prior art comprises a bottom frame, a light source (the light source can adopt a light bar, a fluorescent tube or an LED tube) and a grille, wherein the light source is fixed on the bottom frame, and the grille is arranged on the light emitting side of the light source. The grille lamp of the prior art has the following disadvantages: the mode of arranging the grille is not beneficial to the height control of the grille lamp, so that the packaging and transportation cost is increased; the cost of the grille is high, which is not beneficial to the cost control of the whole lamp; when the grille is arranged, the light loss is large, and a dark area is easy to form at the grille, so that the light is not easy to exit.

Either flat panel lamps or grille lamps require a power supply means for powering the light source. When the power supply device supplies power to the light source, external current needs to be processed (such as rectification, filtering and the like) to enable the light source to have better light emitting effect, so that the power supply device generally has a larger volume, in the prior art, the power supply is generally arranged on the back of the lamp through an independent power supply box, but the arrangement of the power supply device to a certain extent leads to the increase of the overall height of the lamp.

Meanwhile, the fixation of the lamp is also a problem that the lamp has to face, in the prior art, the fixation of parts in the lamp is generally realized by adopting a rivet or gluing mode, for example, a bottom plate and a lamp shade of the lamp are fixed by adopting a rivet mode, but the rivet mode is easy to form a dark area at a connecting position; the adhesive mode is adopted, and a certain reliability risk problem exists.

In view of the above, how to design an LED lighting device and how to balance the relationship between the power supply arrangement and the lamp height is a technical problem to be solved by those skilled in the art in view of the drawbacks and disadvantages of the LED lighting device in the prior art.

As shown in fig. 1 to 6, an LED lighting apparatus according to an embodiment of the present utility model includes: a base 1, a light source 2, an optical member 3, and a power supply 4. Wherein the light source 2 is electrically connected with the power supply 4, the light source 2 is disposed on the base 1, and the optical member 3 is disposed in the light emitting direction of the light source 2.

Referring to fig. 9, the base 1 of the present embodiment has a bottom plate 11 and a sidewall 12, wherein the sidewall 12 is disposed at the outer edge of the bottom plate 11 to form a cavity 101 between the sidewall 12 and the bottom plate 11. The light source 2 is arranged in the cavity 101. The base 1 may be made of metal, such as iron or stainless steel, to increase its heat dissipation. In some embodiments, the base 1 is formed as a unitary structure, and the side wall 12 is formed by directly bending with respect to the bottom plate 11. In some embodiments, the base 1 is formed as a unitary structure, which is directly formed by stamping or stretching, so that it has better structural strength. In some embodiments, the base 1 may also be made of plastic.

Referring to fig. 6 and 7, in the present embodiment, the light source 2 may be directly fixed to the bottom plate 11 of the base 1. Specifically, the light source 2 includes an LED lamp bead 21 and a circuit board 22, wherein the LED lamp bead 21 is fixed on the circuit board 22, and the light source 2 is directly fixed to the bottom plate 11 of the base 1 through the circuit board 22. In some embodiments, the circuit board 22 is directly secured to the bottom plate 11 of the base 1 by means of adhesive. In some embodiments, the light source 2 may be clamped to the bottom plate 11 of the base 1 through the circuit board 22. In some embodiments, the light source 2 may be directly fixed to the bottom plate 11 of the base 2 by welding. In the above embodiment, the light source 2 and the bottom plate of the base 1 form a heat conduction path, so that the heat generated during the operation of the LED lamp beads 21 can be quickly conducted to the base 1, and the heat is dissipated through the base 1, so as to improve the heat dissipation efficiency. Referring to fig. 6, in some embodiments, two columns of LED light beads 21 are provided on the circuit board 22. Referring to fig. 13 and 15, in some embodiments, the LED light beads 21 on the circuit board 22 are provided in 1 column.

Referring to fig. 12, 13 and 15, in an embodiment, the base 1 may be provided with a positioning unit 102 for positioning the light source 2. The positioning unit 102 includes a strip-shaped groove formed on the base plate 11, and the circuit board 22 of the light source 2 is at least partially or entirely accommodated in the groove, so that the position of the circuit board 22 is relatively fixed and configured as the base plate 11. In addition, the grooves are punched on the bottom plate 11, which corresponds to the reinforcing ribs arranged on the bottom plate 11, so that the flexural strength of the bottom plate 11 can be increased. In this embodiment, the thickness dimension of the circuit board 22 is approximately the same as the depth dimension of the groove. The electrical connection unit 24 may be attached to the base plate 11 and electrically connected to the circuit board 22 located in the recess. The electrical connection unit 24 is attached to the base plate 11 and can press the circuit board 22 to limit loosening of the circuit board 22. In addition, the electrical connection unit 24 may be fixed to the base plate 11, for example, by glue or screws, so as to increase stability thereof and prevent the electrical connection between the electrical connection unit 24 and the circuit board 22 from being disabled due to disconnection caused by loosening of the electrical connection unit 24.

Referring to fig. 1 to 3, in the present embodiment, the optical member 3 includes an optical unit 31 and a mounting unit 32, and the mounting unit 32 is correspondingly matched with the base 1. Specifically, the mounting unit 32 is connected to the side wall 12 of the base 1. The mounting unit 32 may be disposed on the inner or outer side of the sidewall 12. In the present embodiment, the mounting unit 32 is disposed outside the side wall 12, so that the optical member 3 entirely covers one side of the base 1 in the light emitting direction of the LED lighting device. When the LED lighting apparatus is mounted to a ceiling, the base 1 is not exposed, and the user cannot directly see the base 1. Only one group of optical units 31 is provided.

Referring to fig. 10 and 16, in one embodiment, the mounting unit 32 includes a hole 302 provided on the optical member 3. Accordingly, the base 1 is also provided with holes corresponding to the holes 302, so that the rivet can pass through the holes corresponding to the optical component 3 and the base 1, and fix the optical component 3 and the base 1.

Referring to fig. 21 to 24, in one embodiment, the mounting unit 32 is disposed at the outer edge of the optical member 3, and includes a wall portion 321, where the wall portion 321 is disposed around the side wall 12 of the base 1, and is disposed outside the side wall 12. The wall 321 is provided with a bending portion 3211, and the bending portion 3211 wraps around or abuts against an end portion of the side wall 12 in the thickness direction of the LED lighting device, so that the side wall 12 can be clamped by the bending portion 3211 and the optical member 3 itself, so that the optical member 3 is fixed to the base 1. In addition, by fixing the optical member 3 to the base 1 without providing a fastener (such as a bolt or a rivet), the fastener is prevented from being provided on the light-emitting surface of the optical member 3 to affect the light-emitting surface of the optical member 3 (for example, a local dark spot of the light-emitting surface of the optical member 3 due to the fastener), and the integrity and the appearance of the optical member 1 can be ensured.

The optical member 3 is molded from a plastic material. When the optical member 3 is sleeved outside the base 1, the wall portion 321 of the light member 3 may be deformed by hot pressing to form the bent portion 3211.

In other embodiments, when the optical member 3 is sleeved outside the base 1, the wall 321 and the side wall 12 of the base 1 may be fixed by a buckle, a fastener, or the like.

The wall 321 of the optical member 3 is disposed outside the side wall 12 and fixed, so that the structure can be simplified, the frame of the lamp can be reduced, the aesthetic degree and the light emitting effect can be improved, and the dark area caused by the frame can be reduced.

Referring to fig. 1 to 4, the optical unit 31 in the present embodiment includes a plurality of first optical members 311 (light transmitting members), and light generated when the light source 2 operates is transmitted through the first optical members 311. The light source 2 comprises a number of LED arrays 23, the LED arrays 23 comprising at least one LED lamp bead 21. In this embodiment, each LED array 23 includes a plurality of LED light beads 21. The LED array 23 corresponds to the first optical member 311, that is, the LED array 23 is arranged in one-to-one correspondence with the first optical member 311, both of which are provided with the same number. In other embodiments, the number of the first optical members 311 may be set to be larger than the number of the LED arrays 23.

In the present embodiment, the LED beads 21 in the LED array 23 correspond to only the first optical member 311, that is, the beads 21 in the LED array 23 are entirely covered with the first optical member 311. At least a part of the light generated when the LED beads 21 in the LED array 23 are operated is emitted from the first optical member 311. Specifically, in the present embodiment, the first optical member 311 has a light-emitting surface 3111, a space is provided between the light-emitting surface 3111 and the LED beads 21 of the LED array 23, and light generated when the LED beads 21 operate is emitted from the light-emitting surface 3111.

Referring to fig. 6 and 7, in the present embodiment, a plurality of LED beads 21 of the LED array 23 are disposed along a first direction. The first optical member 311 (or the light-emitting surface 3111) extends in the first direction.

Referring to fig. 1 to 4, in the present embodiment, the light-emitting surface 3111 has a main body portion 31111 extending along a first direction and end portions 31112 located at two ends of the main body portion 31111 in the first direction. The cross section of the main body 31111 (the cross section in the width direction of the light-emitting surface 3111) is arc-shaped, and the end 31112 is configured as an arc-shaped surface, so that the light-emitting surface 3111 has better light-emitting effect. In addition, when the arc surface is compared with a plane, and light emitted by the LED lamp beads 21 reaches the arc surface, light reflection is reduced, and light emitting efficiency can be improved, so that light efficiency is improved. In addition, the light-emitting surface 3111 is closer to the LED lamp bead 21 than the second optical member 312, and when the LED lamp bead 21 works, the light-emitting surface 3111 has a higher temperature than the second optical member 312, so that the light-emitting surface 3111 adopts an arc shape, the structural strength can be improved, and the deformation resistance is better when the light-emitting surface 3111 is heated. In other embodiments, the light-emitting surface 3111 may be configured as a spherical surface or a planar surface.

In an embodiment, the first optical member 311 is configured to have a light diffusing function to increase the light emitting angle of the light source 2, and avoid the light from being concentrated, which causes discomfort to the vision. In one embodiment, the first optical member 311 has a light diffusion function due to its own material property, such as plastic or acrylic. In one embodiment, the first optical member 311 is coated with a diffusion coating or provided with a diffusion film (not shown) on its surface so as to have a light diffusion function.

Referring to fig. 1 and 2, in the present embodiment, the optical unit 31 further has a plurality of second optical members 312 (antiglare components) corresponding to the first optical members 311, the second optical members 312 being configured to reflect at least a part of the light emitted from the first optical members 311, and at least a part of the light emitted from the first optical members 311 is transmitted through the second optical members 312. At least a portion of the light transmitted through the second optical member 312 may be emitted from the adjacent second optical member 312, or at least a portion of the light transmitted through the second optical member 312 may be reflected and emitted from the second optical member 312 to avoid a dark area formed at the second optical member 312, thereby improving the aesthetic appearance of the LED lighting device when it is lighted. In addition, the second optical member 312 reflects at least a part of the light emitted from the first optical member 311, and it plays a role of blocking light to some extent, so that glare can be reduced.

Referring to fig. 4, in the present embodiment, the first optical member 311 has a midpoint of a bottom in a cross section in the width direction of the first optical member 311. The second optical member 312 has a proximal end and a distal end in the height direction of the LED lighting apparatus, wherein the proximal end is closer to the light source 2 mated therewith than the distal end. The distal end is the bottommost end of the second optical member 312 in the height direction of the LED lighting device. The angle a between the line connecting the midpoint and the distal end and the lower end face of the LED lighting device (the plane in which the second connecting wall 314 lies) is between 10 degrees and 45 degrees. Further, the angle a between the line connecting the midpoint and the distal end and the lower end face (the plane of the second connecting wall 314) of the LED lighting device is between 25 degrees and 35 degrees. Thus, a part of the direct light emitted from the first optical member 311 can be shielded, and glare can be reduced.

The second optical member 312 includes one or more sets of optical walls 3121, and the optical walls 3121 are configured to have reflective and light-transmissive functions. The optical wall 3121 is disposed around the first optical member 311. In the present embodiment, one set of the second optical members 312 has 4 sets of optical walls 3121,4, the optical walls 3121 are connected in sequence, and the optical walls 3121 are configured to be planar. In some embodiments, the set of second optical members 312 may have only one set of optical walls 3121, the optical walls 3121 being annular in cross-sectional shape. The optical wall 3121 may be a sloped surface that is inclined with respect to the base plate 11. As shown in fig. 10 and 16, in an embodiment, the adjacent optical walls 3121 are smoothly transited, such as by using a circular arc transition, so as to avoid forming a dark area at the included angle between the adjacent optical walls 3121, and to enable better reflection effect between the adjacent optical walls 3121.

Referring to fig. 4, in the present embodiment, the optical walls 3121 of the adjacent second optical members 312 are connected by a first connection wall 313. At least a portion of the light transmitted from the second optical member 312 is emitted from the first connection wall 313 to avoid the formation of a dark region at the first connection wall 313. The thickness of the first connection wall 313 is greater than the thickness of the optical wall 3121 to provide better connection strength, and the optical wall 3121 is provided thinner such that there is less light loss at the optical wall 3121.

Referring to fig. 1 and 8, in the present embodiment, a reinforcing structure 316 may be disposed on the second optical member 312 to enhance structural strength. Specifically, the reinforcement structure 316 is disposed between the optical walls 3121 of adjacent second optical members 312. That is, the optical walls 3121 between adjacent second optical members 312 are connected by the reinforcement structure 316. In this embodiment, the reinforcement structure 316 is a thin-walled structure.

Referring to fig. 1 and 5, in the present embodiment, the optical unit 31 further includes a second connection wall 314, the mounting unit 32 is connected to the adjacent second optical member 312 through the second connection wall 314, and at least a portion of the light transmitted through the second optical member 312 is emitted from the second connection wall 314 to avoid a dark area at the second connection wall 314.

Referring to fig. 12 and 14, in some embodiments, the second connecting wall 314 is adjacent to the end wall 13. Also, the surface of the second connecting wall 314 is substantially flush with the end wall 13 to increase aesthetics. In this embodiment, an inner recess 131 is provided at the end wall 13, and the second connecting wall 314 is disposed at the inner recess 131, so that the surface of the second connecting wall 314 is flush or substantially flush with the end wall 13.

The wall thickness of the first optical member 311 and the second optical member 312 in this embodiment is smaller than the wall thickness of the first connection wall 313 or the second connection wall 314, respectively. The first optical member 311 is mainly used for light output of the light source 2 (the light loss will be increased due to the excessively thick wall thickness), the second optical member 312 is mainly used for reflection and light transmission (the light loss will be increased due to the excessively thick wall thickness), and the first connecting wall 313 and the second connecting wall 314 are mainly used for structural connection, so that the strength is required to be ensured, and the above wall thickness arrangement can respectively meet the optical and structural requirements.

In this embodiment, the optical member 3 is constructed as a unitary structure.

Referring to fig. 1 to 6, in the present embodiment, the optical member 3 has a first region 301 corresponding to the bottom plate 11 of the base 1, and a second region 302 corresponding to the side wall 12. Wherein the second region 302 is configured for connection with the sidewall 12. Specifically, the second region 302 configures the aforementioned mounting unit 32. In this embodiment, when the LED lighting device is operated, the light source 2 is turned on, and at least 80% of the first area 301 has light emitted, so as to obtain more uniform light. Further, when the LED lighting device is operated, the light source 2 is turned on, and at least 90% of the first area 301 has light emitted, so as to obtain more uniform light. Further, when the LED lighting device is operated, the light source 2 is turned on, and the areas on the first area 301 all have light emission, so as to obtain uniform light emission.

In this embodiment, the first region 301 may include the first optical member 311, the second optical member 312, the first connecting wall 313 and the second connecting wall 314.

Referring to fig. 6 and 7, the circuit boards 22 in the present embodiment may be provided with a plurality of groups, and one or more groups of LED arrays may be provided on each group of circuit boards 22. The embodiment further comprises an electrical connection unit 24, and the LED lamp beads 21 on the different circuit boards 22 are electrically connected through the electrical connection unit 24. In some embodiments, electrical connection unit 24 employs wires. In some embodiments, the electrical connection unit 24 is a flexible circuit board, and the flexible circuit board is directly soldered to the circuit board 22, specifically, the electrical connection unit 24 is attached to the circuit board 22 and directly soldered to the circuit boards 22, so as to realize electrical connection. In some embodiments, the electrical connection unit 24 is connected using a PCB board.

Referring to fig. 5, in the present embodiment, the optical unit 31 may be provided in plural groups, for example, 2 groups or 4 groups. Adjacent optical units 31 are connected by a third connecting wall 315. A receiving space is formed between the third connecting wall 315 and the bottom plate 11, and the power source 4 is disposed in the receiving space. Because the power supply 4 is arranged inside the LED lighting equipment, compared with the power supply 4 arranged outside the base 1, the power supply 4 does not occupy the extra height space of the LED lighting equipment, and the height of the LED lighting equipment can be reduced. In this embodiment, the height of the LED lighting device is less than 35 millimeters. Further, the height of the LED lighting device is less than 30 millimeters. Still further, the height of the LED lighting device is between 20 mm and 30 mm.

Referring to fig. 10 to 14, in an embodiment, the power source 4 may also be disposed on the back surface of the bottom plate 11, and at this time, there is no need to provide a receiving space on the optical unit 31, i.e. there is no need to provide the third connecting wall 315 (as shown in fig. 3 and 5), so that the optical unit 31 has better continuity, and the light emitting effect and the appearance are improved.

In one embodiment, the base 1 is further provided with an end wall 13, and the end wall 13 is formed on the outer edge of the base 1 and is connected to the side wall 12. The end wall 13 is disposed parallel or substantially parallel to the floor 11. The side wall 12 and the end wall 13 form a containing space (a height difference is formed between the end wall 13 and the bottom plate 11, the power supply 4 is at least partially arranged in the height difference), and the power supply 4 is at least partially positioned in the containing space in the height direction, so that the height space of the power supply 4 occupied by the LED lighting device is reduced.

In one embodiment, at least half of the power supply 4 in the height direction is located in the accommodating space. The length of the power supply 4 is 80%, 85%, 90% or 95% or more of the length of the base 1, so that the power supply 4 can increase the structural strength of the base 1 in the longitudinal direction.

Referring to fig. 21 to 25, in one embodiment, a power source is disposed between the base 1 and the optical member 3. Specifically, the surface of the base 1 is formed with a convex portion 103 protruding outwards (towards the back of the base 1), the convex portion 103 forms a concave portion 104 on the front of the base 1, and the power source may be partially or completely located in the concave portion 104. Further, a cover 105 may be disposed on the base 1, where the cover 105 is covered on the concave portion 104, so as to form a containing space 106 between the concave portion 104 and the cover 105. The power supply is located inside the accommodating space 106. The cover 105 is protruding from the front surface of the base 1, so the volume of the accommodating space 106 is larger than the volume of the concave portion 104.

In the embodiment, the power supply does not need to be additionally provided with a separate power supply box, so that the structure can be simplified, and the cost can be saved.

As shown in fig. 26 and 27, in some embodiments, the convex portion 103 is provided with a set. When two sets of LED lighting devices are stacked back to back, one set of LED lighting devices is rotated by a certain angle (such as 90 degrees, 180 degrees or 270 degrees), the convex parts 103 of the two sets of LED lighting devices are arranged in a staggered manner, so that the total height of the two sets of LED lighting devices is smaller than 2 times of the height of the single set of LED lighting devices when the two sets of LED lighting devices are stacked back to back. Therefore, when two or more groups of LED lighting devices are stacked in the above method, the package size can be reduced, and the transportation cost can be reduced. In this embodiment, a coordinate system is established on the back of the LED lighting device, and the center of the LED lighting device is taken as the origin, so that the convex portion 103 may be located completely in one of the quadrants (as shown in fig. 27), or completely in both quadrants (as shown in fig. 26).

As shown in fig. 28, in some embodiments, the protrusions 103 are provided in two sets with a gap 107 between the two sets of protrusions 103. The two sets of protrusions 103 may be arranged extending in the same direction, for example along the length or width of the LED lighting device. When two sets of LED lighting devices are stacked back to back, one set of LED lighting devices is rotated by 90 degrees, and the convex parts 103 of the two sets of LED lighting devices are arranged in a staggered mode, so that when the two sets of LED lighting devices are stacked back to back, the total height of the two sets of LED lighting devices is smaller than 2 times of the height of the single set of LED lighting devices, and the gap 107 can prevent the two sets of LED lighting devices from being stacked back to back, and the two sets of convex parts 103 interfere with each other. In the present embodiment, the gap 107 is located at the center of the base 1, and its dimension in the extending direction of the convex portion 103 is larger than the width dimension of the convex portion 103.

As shown in fig. 25, 29 and 30, in the present embodiment, the convex portion 103 is located at a middle position in the length or width direction of the LED lighting apparatus (the base 1) so that the LED lighting apparatus as a whole has a substantially symmetrical structure. In this embodiment, a set of covers 105 is engaged with two sets of concave portions 104, respectively. The cover 105 is provided with a plugging wall 1051, and the base 1 is correspondingly provided with a plugging hole 108, so that the cover 105 can be fixed to the base 1 when the plugging wall 1051 on the cover 105 is inserted into the plugging hole 108 of the base 1.

The distance between the LED lamp beads 21 and the cover body 105 is controlled to be larger than 15mm. In addition, the included angle a between the side wall of the cover 105 and the surface of the base 1 can be controlled to be greater than 120 degrees. Thus, the influence of the cover 105 on the light emission of the LED lamp beads 21 can be prevented or reduced.

Referring to fig. 14, the LED lighting device in an embodiment may further comprise a hanger 5, the hanger 5 being configured for mounting the LED lighting device to a bracket (commonly known as a keel) of a ceiling. The hanging support 5 can be made of metal, such as copper or iron. One end of the hanging support 5 is fixed on the end wall 13, and the other end can be correspondingly bent to hang the hanging support on the bracket.

Referring to fig. 14, fig. 17 to fig. 20, the LED lamp beads 21 of the LED array 23 have a beam angle a, and the definition of the beam angle (the light intensity reaches 50% of the normal light intensity, and the included angle formed by the two sides is the beam angle) is the prior art, which is not described here again. Alternatively, the beam angle a may take a value between 100 and 130 degrees. The LED lamp beads 21 project onto the inner surface of the first optical member 311 within the range of the beam angle a boundary, and form a projection area m (the projection area m is a curved surface or a plane or other irregular surface) on the inner surface of the first optical member 311, wherein the area of the projection area m is greater than 500 square millimeters. To avoid the formation of a granular sensation on the first optical member 311 when the LED beads 21 are lit, the illumination intensity on the projection area m is less than 50000 lux without considering the influence of the adjacent LED beads 21.

The size of the projection area m depends on the distance from the LED lamp beads 21 to the first optical member 311. When the distance is larger, the thickness of the optical unit 3 is larger (which may cause an increase in the thickness of the entire lamp), which is disadvantageous for cost control, and when the distance is smaller, the projected area m may be smaller than 500 square millimeters, which makes illuminance difficult to control, and forms a granular feel. Thus, in the present embodiment, the distance from the LED lamp beads 21 to the first optical member 311 is controlled to be between 6 and 15 mm. And, the illumination intensity on the projection area m is greater than 10000 lux without considering the influence of the adjacent LED beads 21. When the projection area m is non-planar, the shortest distance from the center of the surface of the LED lamp bead 21 to the first optical member 311 within the beam angle a can be used as the distance to be controlled.

The luminous flux of the LED lamp beads 21 is L. In the case where the LED beads 21 in the LED array 23 are provided in only one row, the projection areas m of the LED beads 21 of the same LED array 23 on the inner surface of the first optical member 311 may be partially overlapped. Considering the superposition of the projection areas m of different LED lamp beads 21 on the inner surface of the first optical member 311, the illuminance at any position within any one projection area m does not exceed 5L/m, so as to prevent strong light from forming when the projection areas m of the LED lamp beads 21 are superimposed. In one embodiment, the illuminance at any position in any projection area m is not more than 4L/m, so as to prevent strong light from forming when the projection areas m of the LED beads 21 are superimposed. In one embodiment, the illuminance at any position in any projection area m is not more than 3L/m, so as to prevent strong light from forming when the projection areas m of the LED beads 21 are superimposed. In one embodiment, the illuminance at any position in any projection area m is not more than 2L/m, so as to prevent strong light from forming when the projection areas m of the LED beads 21 are superimposed.

One of the factors affecting the superposition of the projection areas m of the LED beads 21 is the distance between the LED beads 21. In one embodiment, the center-to-center distance between the LED beads 21 is controlled to be greater than 4mm or 4.5mm or more.

In one embodiment, the number of LED light beads in the LED array 23 is n, and the number of projection areas m overlapped by any area of any projection area m is less than or equal to n. In one embodiment, the number of LED beads in the LED array 23 is n, and the number of projection areas m overlapped by any area of any projection area m is smaller than n.

The total projected area on the inner surface of the first optical member 311 is M. As an example, taking fig. 20 as an illustration, when the LED array 23 has two LED beads 21, and the projection areas M of the two LED beads 21 overlap, the total projection area on the inner surface of the first optical member 311 is formed by the boundary between the two LED beads 21 and the projection area M of the inner surface of the first optical member 311, that is, the total projection area M is the sum of the areas of the two LED beads 21 and the projection area M of the inner surface of the first optical member 311, and then the area of the overlapping area is subtracted.

The luminous intensity near the optical axis of the beam angle a is larger than that of the boundary region of the beam angle a, namely, the projection region m is seen alone, and the illumination intensity in the range is not uniform. Thus, it is possible to provide that 30%, 35%, or 40% or more of the total projected area M on the inner surface of the first optical member 311 has a superposition of at least two sets of projected areas M to promote uniformity of illumination within the total projected area M. However, in order to avoid overlapping of excessive projection areas M and cause unevenness in illumination intensity, an area of not more than 25%, 20% or 18% of the total projection area M on the inner surface of the first optical member 311 may be set to have overlapping of 4 or more groups of projection areas M.

Based on the above, the present embodiment can realize uniformity of light with only 1 optical unit (no lens is provided), simplify the structure, and reduce the material cost.

As shown in fig. 21, 31 and 32, in one embodiment, a first cavity 3001 is formed in the first optical member 311 (between the first optical member 311 and the surface of the base 1), and a second cavity 3002 is formed between adjacent second optical members 312. The first optical member 311 is connected to the optical wall 3121 of the second optical member 312 in the length direction thereof, and communicates the first cavity 3001 and the second cavity 3002. When the LED lamp beads 21 emit light, at least part of the light enters the second cavity 3002 after being reflected by the base 1 and the first optical member 311, and is transmitted out from the corresponding optical wall 3121 and/or the first connection wall 313, so as to enhance the light emitting effect of the optical member 3.

As shown in fig. 33 to 38, in an embodiment, a first cavity 3001 is formed in the first optical member 311 (between the first optical member 311 and the surface of the base 1), and a second cavity 3002 is formed between adjacent second optical members 312. The first optical member 311 is not connected (not directly connected) to the optical wall 3121 of the second optical member 312 in both the length direction and the width direction thereof, so that the first cavity 3001 and the second cavity 3002 are not connected (not including the connection caused by the assembly gap, where the assembly gap is smaller than 5mm, both can be regarded as the first cavity 3001 and the second cavity 3002 are not connected), and the light reflected by the first cavity 3001 and entering the second cavity 3002 when the light source 2 is operated can be reduced, so that the light emitted by the light source 2 is more concentrated and emitted through the first optical member 311 when the light source 2 is operated. As shown in fig. 36 and 38, in other words, the end of the first optical member 312 (i.e., the lower portion of the first optical member 312 in fig. 36 and 38) is spaced from the bottom plate 11 of the base 1 by no more than 5mm, 4 mm, 3 mm, 2 mm or 1 mm to reduce leakage of light emitted from the light source 2 from the gap between the first optical member 312 and the bottom plate 11. In an embodiment, an end portion of the first optical member 312 (in fig. 36 and 38, i.e. a lower portion of the first optical member 312) is at least partially attached to the bottom plate 11 of the base 1, so as to further reduce light leakage.

In one embodiment, the base plate 11 is provided with a positioning groove 111, and the light source 2 is at least partially accommodated in the positioning groove 111 in the height direction thereof. In other words, the circuit board 22 of the light source 2 is at least partially accommodated in the positioning groove 111 in the thickness direction. When the surface of the circuit board 22 does not exceed the positioning groove 111 (i.e., the circuit board 22 is completely accommodated in the positioning groove 111 in the thickness direction), the end 3112 of the first optical member 312 (in fig. 36 and 38, i.e., the lower portion of the first optical member 312) may be directly attached to the base plate 11. When a portion of the circuit board 22 in the thickness direction is accommodated in the positioning groove 111, the end 3112 of the first optical member 312 (in fig. 36 and 38, i.e., the lower portion of the first optical member 312) abuts against the surface of the circuit board 22, and at this time, the end 3112 of the first optical member 312 (in fig. 36 and 38, i.e., the lower portion of the first optical member 312) maintains a distance from the base plate 11, which may be a height of the circuit board 22 exposed to an outer portion of the positioning groove 111.

In an embodiment, the optical wall 3121 has a reflection function, and may reflect a portion of light emitted from the first optical member 311 to reduce light emission of the LED lighting device in a lateral direction of the first optical member 311, so that glare may be reduced. In the present embodiment, on the cross section of the first optical member 311 in the width direction, the optical wall 3121 forms an acute angle a with the optical axis of the LED lamp bead 21. The angle of the acute angle a between the optical wall 3121 and the optical axis of the LED lamp bead 21 is 30 to 60 degrees. The optical wall 3121 includes a wall portion corresponding to the longitudinal direction of the first optical member 311 and a wall portion corresponding to the width direction of the first optical member 311, and the angles of the wall portion corresponding to the longitudinal direction of the first optical member 311 and the wall portion corresponding to the width direction of the first optical member 311 with the optical axis of the LED lamp bead 21 are both within the aforementioned acute angle a. In an embodiment, the included angle between the two corresponding sets of optical walls 3121 in the width direction of the first optical member 311 is smaller than the beam angle of the LED lamp beads 21, so as to play a role of blocking light, and thereby reduce the glare value. Also, the included angle between the two sets of optical walls 3121 corresponding in the width direction of the first optical member 311 (i.e., twice the aforementioned acute angle a) is greater than 70 degrees to prevent the light emitting angle of the LED lighting apparatus from being excessively limited.

Fig. 39 shows a partially cut-away structural schematic view of the LED lighting device in an embodiment, which is horizontally installed and emits light downward, showing a cross section in the width direction of the first optical member 311. In this embodiment, in the cross section of the first optical member 311 in the width direction, the optical wall 3121 of the second optical member 312 has a lower end point, the lower end point extends along a direction and forms a straight line, the straight line L1 is tangent to the outer surface of the first optical member 311, and an included angle B between the straight line L1 and a horizontal plane (i.e., the light emitting surface of the LED lighting device, which is parallel or substantially parallel to the horizontal plane when the LED lighting device is installed along the horizontal plane) is greater than 10 degrees, 12 degrees, 14 degrees, 16 degrees, or 18 degrees. In one embodiment, the angle B between the straight line L1 and the horizontal plane (i.e. the light-emitting surface of the LED lighting device, which is parallel or substantially parallel to the horizontal plane when the LED lighting device is mounted horizontally) is in the range of 15 to 25 degrees. In one embodiment, the angle B between the straight line L1 and the horizontal plane (i.e. the light-emitting surface of the LED lighting device, which is parallel or substantially parallel to the horizontal plane when the LED lighting device is mounted horizontally) is in the range of 18 to 20 degrees. When the human eye is at a certain position with the first optical member 311 (or the LED lighting device) (when the angle C between the line from the human eye to the first optical member 311 and the light emitting surface of the LED lighting device is smaller than the aforementioned angle B), the human eye will not directly observe the direct light emitted from the first optical member 311, so that the glare can be reduced. From another angle, a straight line L is provided, one end of the straight line L is connected to the lower end of the optical wall 3121, and the other end of the straight line L is tangent to the outer surface of the first optical member 311, and an included angle B between the straight line L and a horizontal plane (i.e., a light emitting surface of the LED lighting device, which is parallel or substantially parallel to the horizontal plane when the LED lighting device is installed along the horizontal plane) is greater than 10 degrees, 12 degrees, 14 degrees, 16 degrees, or 18 degrees. In some embodiments, the angle B between the line L1 and the horizontal is in the range of 15 to 25 degrees. In some embodiments, the angle B between the straight line L1 and the horizontal plane is 18 to 20 degrees. The cross-sectional shape of the optical wall 3121 in the present embodiment may not be set to be flat within the scope as long as the position of the lower end thereof satisfies the above-described requirements, and may function to reduce glare.

Fig. 40 shows a partially cut-away structural schematic view of an LED lighting device in an embodiment, which is horizontally installed and emits light downward, showing a cross section in the length direction of the first optical member 311. In this embodiment, in a cross section of the first optical member 311 in the length direction, the optical wall 3121 of the second optical member 312 has a lower end point, the lower end point extends along a direction and forms a straight line, the straight line L is tangent to the outer surface of the first optical member 312, and an included angle D is formed between the straight line L2 and a horizontal plane (i.e., the light emitting surface of the LED lighting device, which is parallel or substantially parallel to the horizontal plane when the LED lighting device is mounted along the horizontal plane). The value of the included angle D is smaller than the value of the included angle B. In some embodiments, the included angle D has a value greater than 10 degrees, 11 degrees, 12 degrees, or 13 degrees. In one embodiment, the included angle D is in the range of 10 to 20 degrees. In one embodiment, the included angle D is in the range of 12 to 16 degrees. When the human eye is at a certain position with the first optical member 311 (or the LED lighting device) (when the angle E between the line from the human eye to the first optical member 311 and the light emitting surface of the LED lighting device is smaller than the aforementioned angle D), the human eye will not directly observe the direct light emitted from the first optical member 311, so that the glare can be reduced. From another angle, a straight line L2 is provided, one end of the straight line L2 is connected to the lower end of the optical wall 3121, and the other end of the straight line L2 is tangent to the outer surface of the first optical member 311, and an included angle D between the straight line L2 and a horizontal plane (i.e., the light emitting surface of the LED lighting device, which is parallel or substantially parallel to the horizontal plane when the LED lighting device is installed along the horizontal plane) is in a range of 10 to 20 degrees. In some embodiments, the included angle D has a value in the range of 12 to 16 degrees. The cross-sectional shape of the optical wall 3121 in the present embodiment may not be set to be flat, and may function to reduce glare as long as the position of the lower end thereof satisfies the above-described requirements.

Fig. 41 shows a partially cut-away structural schematic view of an LED lighting device in an embodiment, which is horizontally installed and emits light downward, showing a cross section in the width direction of the first optical member 311. In this embodiment, on the cross section of the first optical member 311 in the width direction, the two groups of optical walls 3121 corresponding to the second optical member 312 of the LED lamp bead 21 have lower end points, the included angle between the center of the light emitting surface of the LED lamp bead 21 and the connecting lines L3 and L4 of the lower end points of the two groups of optical walls 3121 is F, and the value of the included angle F is greater than 0.8 times of the beam angle a of the LED lamp bead 21 (the included angle formed by the two sides is the beam angle a where the light intensity of the LED lamp bead 21 reaches 50% of the normal light intensity), so as to prevent the excessive light emitting of the LED lamp bead 21 by the optical walls 3121 from forming shielding, thereby causing light loss and further reducing the light emitting efficiency. In some embodiments, the value of the included angle F is smaller than 1.2 times of the beam angle a of the LED lamp bead 21 (the included angle formed by the two sides of the LED lamp bead 21 reaching 50% of the normal light intensity is the beam angle a, and the value of the beam angle a at this place is about 120 degrees) to ensure that the optical wall 3121 has a certain light blocking effect to play a role of reducing glare.

Fig. 42 shows a partially cut-away schematic construction of an LED lighting device in an embodiment, which is horizontally mounted and emits light downward, showing a cross section in the length direction of the first optical member 311. In this embodiment, on a cross section of the first optical member 311 in the length direction, the LED array 23 corresponding to the first optical member 311 is provided, and the two sets of optical walls 3121 of the second optical member 312 correspond to the LED array 23 disposed in the first optical member 311, each of the two sets of optical walls 3121 has a lower end point, an included angle between a midpoint of the light emitting surface of any one LED lamp bead 21 in the LED array 23 corresponding to the first optical member 311 and a connection line L5, L6 of the lower end points of the two sets of optical walls 3121 is G, the value of the included angle G is greater than a beam angle a of the LED lamp bead 21 (the included angle formed by the two sides is about 120 degrees when the light intensity of the LED lamp bead 21 reaches 50% of the normal light intensity), so as to prevent the excessive light emitting of the LED lamp bead 21 from forming a shielding, thereby reducing the light emitting efficiency. In some embodiments, the value of the included angle G is smaller than 1.2 times of the beam angle a of the LED lamp bead 21 (the included angle formed by the two sides of the LED lamp bead 21 is equal to the beam angle a at 50% of the normal light intensity), so as to ensure that the optical wall 3121 has a certain light blocking effect, so as to reduce glare.

In one embodiment, there is only one thermal resistance layer (i.e. the optical member 3) in the optical axis direction (light emitting direction) of the LED lamp bead 21, and when the LED lamp bead 21 is operated, at least part of the heat generated by the LED lamp bead is radiated to the thermal resistance layer, and is dissipated outwards through the thermal resistance layer. Compared with the LED lamp beads 21, the LED lamp beads need to radiate heat outwards in the direction of the optical axis through a plurality of groups of thermal resistance layers (at least two groups of lamp covers, lenses, diffusion plates or light guide plates are usually arranged in the prior art so as to achieve the effect of uniform light emission, but the components form the thermal resistance layers), and the heat radiation efficiency is improved.

In one embodiment, only one layer of light-transmitting material (i.e. the optical member 3) is provided in the optical axis direction (light-emitting direction) of the LED lamp bead 21, and when the LED lamp bead 21 works, the generated light is emitted to the light-transmitting material and is emitted from the LED lighting device after passing through the light-transmitting material. Compared with the LED lamp beads 21, the light-emitting efficiency is improved because the LED lamp beads need to emit light to the optical axis direction through multiple groups of light-transmitting materials (at least two groups of lamp covers, lenses, diffusion plates or light guide plates are generally arranged in the prior art to achieve the effect of uniform light-emitting, but the components can cause certain light loss). In some embodiments, the light extraction efficiency of the LED lighting device is greater than 80%, 85%, or 90%. The light extraction efficiency here refers to the ratio of the luminous flux emitted from the LED lighting device to the total luminous flux generated by the LED lamp beads 21.

In one embodiment, the light-transmitting component (the first optical component 311) and the anti-glare component (the second optical component 312) of the LED lighting device are made of the same layered material and are integrated.
