In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0038] Existing stick lights have a single light output mode and uneven light output, which affects the user experience. Therefore, an LED light is proposed to solve the above problems. Therefore, an LED light is proposed to solve the above problems.

[0039] The scheme is further illustrated by the following examples:

[0040] Figure 1 Schematic diagram of an LED lamp according to an embodiment of the present invention. Figure 2 yes Figure 1 Schematic diagram of an exploded view of an LED lamp. Figure 3 yes Figure 1 Schematic diagram of the LED light board. Figure 4 yes Figure 1 Another schematic diagram of the LED light board.

[0041] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The LED lamp of this embodiment can be used as a fill light device such as a stick light.

[0042] Specifically, the LED lamp may include a housing 10 , a lamp board 20 , a light guide plate 30 and a reflective plate 40 .

[0043] Among them, a accommodating cavity 11 is formed inside the shell 10, and a light-emitting surface 12 for light to pass through is formed on the surface of one side of the shell 10, that is, the shell on the side of the light-emitting surface 12 is made of a translucent material, so that light can pass through the shell 10 and be emitted from the accommodating cavity 11 from the light-emitting surface 12.

[0044] The light board 20 is mounted within the accommodating cavity 11 and is located to the side of the light emitting surface 12, that is, the light board 20 is located on the sidewall of the accommodating cavity 11. The light board 20 may include a board body 21 and a light-emitting element 22. The light-emitting element 22 is disposed on the board body 21 and is capable of emitting light. Specifically, the board body 21 may be provided with multiple light-emitting elements 22, and the multiple light-emitting elements 22 may be arranged along a first direction of the board body 21.

[0045] It should be noted that each light emitting element 22 can emit white light under the control of the control circuit.

[0046] Meanwhile, the light emitting element 22 may include at least a first light emitting body 221 and a second light emitting body 222. The first light emitting body 221 and the second light emitting body 222 are arranged along the second direction of the plate 21, and the first direction and the second direction form an angle.

[0047] Specifically, the first direction and the second direction can be perpendicular to each other, that is, the angle between the two is about 90 degrees, and the first direction can be set as the length direction of the plate 21, and the second direction can be set as the width direction of the plate 21. Of course, the first direction and the second direction can also be set at a non-right angle, such as the first direction and the second direction can be set at a 45° or 60° angle. Please refer to Figure 11 , is a schematic diagram of the mixed light effect of the LED lamp of the embodiment of the present application. When the two or more light-emitting bodies capable of emitting different colors or color temperatures included in each light-emitting element 22 arranged along the length direction L are arranged along a second direction intersecting the length direction L at a certain angle, for example, when the second direction is perpendicular to the length direction (that is, the second direction is perpendicular to the length direction), Figure 11Paper), the multiple light-emitting bodies in the light-emitting component 22 are arranged along the thickness direction of the side surface S1 of the light guide plate 30 (that is, the light incident surface) and mixed to form a white light band, which is emitted through the upper surface S2 of the light guide plate 30 (that is, the light-emitting side of the light guide plate), and finally emits light through the soft light cover 50 above the light guide plate 30. The dotted lines in the figure roughly divide the light bands formed by each light-emitting component 22, and a uniform white light with high color consistency formed by multiple white light bands can be formed on the light-emitting side of the light guide plate 30, thereby avoiding the formation of inconsistent local color difference band areas in the length direction of the lamp body, such as local reddish, greenish or bluish. When only a part of the light-emitting bodies in the light-emitting component 22 emit light, a uniform colored light can also be formed. For example, when the blue chip and the red chip in each light-emitting component emit light, purple light is formed in each color band, and uniform purple light is formed on the entire light-emitting surface, without appearing. It should be understood that although the figure illustrates the example of each light band having a clear boundary, in actual products, adjacent light bands may actually intersect as the spacing distances and light-emitting angles of the light-emitting elements 22 vary.

[0048] In this embodiment, the first light emitting body 221 and the second light emitting body 222 have different luminous colors and / or luminous color temperatures, so that different light emitting elements 22 can emit different lights.

[0049] Specifically, the first light-emitting element 221 can be configured as a blue light chip 233, and the second light-emitting element 222 can be configured as a yellow light chip. Of course, the first light-emitting element 221 can also be configured as a warm white light chip 241, and the second light-emitting element 222 can also be configured as a cool white light chip, so that different light-emitting elements 22 can be composed of different light-emitting chips and can emit light of different colors or different color temperatures.

[0050] In addition, the light-emitting element 22 may further include a third light-emitting body 223. The first light-emitting body 221, the second light-emitting body 222, and the third light-emitting body 223 may be respectively configured as a red light chip 231, a green light chip 232, and a blue light chip 233. The red light chip 231, the green light chip 232, and the blue light chip 233 are aligned along the second direction, so that the light-emitting element 22 emits light of different colors or different color temperatures.

[0051] In this embodiment, the first light-emitting body 221 and the second light-emitting body 222 can be packaged as a whole to form a white light LED lamp bead 24. Alternatively, the first light-emitting body 221 and the second light-emitting body 222 can be packaged separately, so that the first light-emitting body 221 and the second light-emitting body 222 are combined into the light-emitting element 22. At the same time, the first light-emitting body 221, the second light-emitting body 222, and the third light-emitting body 223 are packaged as a whole to form an RGB LED lamp bead. That is, the RGB LED lamp bead 23 includes a red light chip 231, a green light chip 232, and a blue light chip 233, while the white light LED lamp bead 24 includes a warm white light chip 241 and a cool white light chip 242, or the white light LED lamp bead 24 can include a blue light chip 233 and a yellow light chip, so that the light-emitting element 22 can emit light of different colors or different color temperatures.

[0052] As an example, the color temperature range of the warm white light chip 241 is around 2700K, or it can also be around 3000K, or in the range of 2600K to 3500K. In contrast, the luminous color temperature of the cold white light chip is higher than that of the warm white light chip. For example, the color temperature of the cold white light chip can be around 6000K, or in the range of 5700K to 7500K. It should be understood that cold white and warm white are relative categories. If 4000K color temperature is used as the boundary for neutral white light (or pure white light), those above this color temperature can be defined as cold white, and those below this color temperature can be defined as warm white, or neutral white light has a certain color temperature range. For example, if the range of 3800K to 5000K is defined as neutral white light, then the low color temperature outside the range is warm white, and the high color temperature outside the range is cold white. In summary, the present application does not limit its specific color temperature value range.

[0053] The light guide plate 30 is installed in the accommodating cavity 11 and is located on the side of the light board 20. The side of the light guide plate 30 is aligned with the light-emitting element 22, so that light emitted by the light-emitting element 22 can enter the light guide plate 30. A light guide surface 31 is formed on one side of the light guide plate 30, and the light guide surface 31 is arranged to face the light emitting surface 12. After being guided by the light guide plate 30, the light emitted by the light-emitting element 22 can be emitted from the light guide plate 30 through the light guide surface 31.

[0054] A reflector 40 is housed within the accommodating cavity 11, and a reflective surface 41 is formed on the surface of the reflector 40 for reflecting light. Specifically, the reflector 40 is positioned on the side of the light guide plate 30 facing away from the light emitting surface 12, with the reflective surface 41 facing the light emitting surface 12. This allows the reflector 40 to collect light emitted from the light-emitting element 22 and the light guide plate 30, and reflect it onto the light emitting surface 12. Therefore, light emitted by the light-emitting element 22, after being guided by the light guide plate 30 and reflected by the reflective surface 41, is guided from the light guide surface 31 and then emitted from the accommodating cavity 11 through the light emitting surface 12.

[0055] Since the light-emitting element 22 includes RGB LED lamp beads 23 and / or white light LED lamp beads 24, and the RGB LED lamp beads 23 include red light chips 231, green light chips 232 and blue light chips 233, and the white light LED lamp beads 24 include warm white light chips 241 and / or cold white light chips 242, the light-emitting element 22 can emit light of different colors by arranging chips in different orders, so that the LED lamp can emit light of different colors or different color temperatures, thereby expanding the application range of the LED lamp and improving the user experience.

[0056] See Figure 3 and Figure 4 On the board 21, two adjacent light-emitting elements 22 are configured as RGB LED beads 23 and white LED beads 24. That is, along the length of the board 21, multiple light-emitting elements 22 are arranged in a repeating pattern of RGB LED beads 23 and white LED beads 24, with each adjacent light-emitting element 22 comprising one RGB LED bead 23 and one white LED bead 24. Furthermore, the RGB LED beads 23 include a red light chip 231, a green light chip 232, and a blue light chip 233 arranged along the width of the board 21, while the white light LED beads 24 include a warm white light chip 241 and a cool white light chip 242 arranged along the width of the board 21. Alternatively, the white light LED beads 24 include a blue light chip 233 and a yellow light chip arranged along the width of the board 21. This allows the RGB LED beads 23 and white light LED beads 24 on the light board 20 to mix and emit soft light, meeting the needs of different scenarios.

[0057] See Figure 4 In some embodiments, the plurality of light-emitting elements 22 on the board 21 can all be configured as RGB LED lamp beads 23. The RGB LED lamp beads 23 include a red light chip 231, a green light chip 232, and a blue light chip 233 arranged along the width of the board 21. However, in two adjacent RGB LED lamp beads 23, the arrangement order of the red light chip 231, the green light chip 232, and the blue light chip 233 along the width of the board 21 is different. This allows the two adjacent RGB LED lamp beads 23 to emit soft light or light of different colors after mixing light, thereby meeting different scene requirements.

[0058] Figure 5 Schematic diagram of an LED lamp according to another embodiment of the present invention. Figure 6 yes Figure 5 Schematic diagram of a cross-sectional view of an LED lamp. Figure 7 yes Figure 1 Schematic diagram of an exploded view of an LED lamp.

[0059] See Figure 5 、 Figure 6and Figure 7 Two light boards 20 can be provided, and the two light boards 20 are respectively located on opposite sides of the accommodating cavity 11 and on opposite sides of the light guide plate 30. At the same time, the opposite sides of the light guide plate 30 are respectively aligned with the light emitting elements 22 on the two light boards 20, so that the light emitted by the light emitting elements 22 can enter the light guide plate 30.

[0060] Figure 8 yes Figure 1 Schematic diagram of the two light panels of the LED lamp. Figure 9 yes Figure 1 Another schematic diagram of the two light panels of the LED lights. Figure 10 yes Figure 1 Another schematic diagram of the two light panels of the LED lamp.

[0061] See Figure 8 In the two light boards 20, the light-emitting components 22 on one light board 20 are RGB LED lamp beads 23, and the light-emitting components 22 on the other light board 20 are white LED lamp beads 24. The RGB LED lamp beads 23 include red light chips 231, green light chips 232, and blue light chips 233 arranged along the width of the board 21, and the white light LED lamp beads 24 include warm white light chips 241 and cool white light chips 242 arranged along the width of the board 21. As a result, light emitted by the two light boards 20, after being guided by the light guide plate 30 and reflected by the reflector 40, can be emitted from the light-emitting surface 12. This allows the LED lamp to emit a richer light, thereby meeting the needs of different scenarios and improving the user experience.

[0062] See Figure 9 The light-emitting components 22 on both light boards 20 are RGB LED lamp beads 23. The RGB LED lamp beads 23 include a red light chip 231, a green light chip 232, and a blue light chip 233 arranged along the width of the board 21. Furthermore, on both light boards 20, the red light chips 231, green light chips 232, and blue light chips 233 of the RGB LED lamp beads 23 are arranged in the same order along the width of the board 21. This allows the LED lamps to emit a richer light, thereby meeting the needs of different scenarios and improving the user experience.

[0063] See Figure 10The light-emitting components 22 on both light boards 20 are RGB LED lamp beads 23, and the RGB LED lamp beads 23 include a red chip 231, a green chip 232, and a blue chip 233 arranged along the width of the light board 20. On the same light board 20, the red chips 231, green chips 232, and blue chips 233 of the multiple RGB LED lamp beads 23 are arranged in the same order. That is, the red chips 231, green chips 232, and blue chips 233 are arranged in the same order along the width of the board 21 for all RGB LED lamp beads 23 on the same light board 20. However, in the two light boards 20, the arrangement order of the red chips 231, green chips 232, and blue chips 233 of the RGB LED lamp beads 23 on one light board 20 is different from the arrangement order of the red chips 231, green chips 232, and blue chips 233 of the RGB LED lamp beads 23 on the other light board 20 along the width of the board 21. For example, the chip arrangement order of all RGB LED lamp beads 23 on one light board 20 is green chip 232, red chip 231, and blue chip 233, while the chip arrangement order of all RGB LED lamp beads 23 on the other light board 20 is red chip 231, green chip 232, and blue chip 233. Therefore, the different chip arrangement orders of the two light boards 20 can enable the LED lamps to emit a richer light, thereby meeting the needs of different scenarios and improving the user experience.

[0064] See Figure 2 、 Figure 6 and Figure 7 A mounting platform 13 is provided on the side of the accommodating cavity 11 facing the light emitting surface 12. Specifically, the mounting platform 13 is provided on the side of the accommodating cavity 11 facing the opening. Specifically, the mounting platform 13 protrudes from the inner wall of the accommodating cavity 11 toward the light emitting surface 12, and the mounting platform 13 is spaced apart from the side wall of the accommodating cavity 11, thereby forming a mounting groove 14 between the side wall of the mounting platform 13 and the side wall of the accommodating cavity 11.

[0065] It should be noted that the mounting groove 14 extends along the length direction of the housing 10 so that the mounting groove 14 can be used to clamp the board 21. Specifically, when the light board 20 is installed, it is clamped into the mounting groove 14 from the end of the housing 10 in the length direction.

[0066] In some other embodiments, two mounting platforms 13 are provided. The two mounting platforms 13 are spaced apart along the width direction of the housing 10 and form mounting grooves 14 with the sidewalls of the housing 10, so that two mounting grooves 14 are formed in the accommodating cavity 11. The two mounting grooves 14 are respectively used to install two light panels 20.

[0067] In this embodiment, the side of the mounting platform 13 facing the light emitting surface 12 is used to press against the side of the reflector 40 facing away from the light guide plate 30 to support the reflector 40 and the light guide plate 30, and to space the reflector 40 from the side of the accommodating cavity 11 facing the light emitting surface 12.

[0068] See Figure 2 and Figure 7 ,

[0069] The housing 10 may include a main body 52 and a diffuser 50.

[0070] In this embodiment, the main body 52 has an opening located on the side of the light guide plate 30 facing away from the reflector 40. In other words, the main body 52 is provided with a receiving cavity 11 with one side open. The diffuser 50 is attached to the main body 52 and covers the opening. The side of the diffuser 50 facing away from the light board 20 forms the light-emitting surface 12. The light guide plate 30 is positioned on the side of the diffuser 50 facing the receiving cavity 11, allowing the diffuser 50 to soften the light emitted from the light guide plate 30.

[0071] At the same time, a clamping step 15 is provided on the side wall of the accommodating cavity 11 , and connecting steps 51 are provided on both opposite sides of the soft light cover 50 , that is, connecting steps 51 are provided on both sides of the soft light cover 50 in the width direction.

[0072] Specifically, the engaging step 15 is located downstream of the mounting platform 13 in the light-emitting direction and spaced apart from the mounting platform 13, allowing the connecting step 51 to engage within the engaging step 15. Furthermore, in this embodiment, both widthwise sides of the light guide plate 30 and the reflector 40 are also located between the engaging step 15 and the mounting platform 13. Consequently, after the diffuser 50 is engaged with the engaging step 15, the side of the diffuser 50 facing the light guide plate 30 can abut against the light guide plate 30, and through the light guide plate 30, the reflector 40 can be pressed against the mounting platform 13, thereby limiting the position of the light guide plates 30 and 40.

[0073] See Figure 2 The LED lamp may further include an end cap 60 .

[0074] The end cap 60 is connected to the end of the housing 10 in the longitudinal direction, thereby forming a side wall of the accommodating cavity 11 in the longitudinal direction. In this embodiment, when the end cap 60 is connected to the end of the housing 10 in the longitudinal direction, the end cap 60 can abut against the end of the diffuser 50 in the longitudinal direction to limit the movement of the diffuser 50 relative to the housing 10 in the longitudinal direction.

[0075] See Figure 7The LED lamp can also include two end covers 60, and when the two end covers 60 are respectively connected to the two ends of the shell 10 in the length direction, the end covers 60 can push against the ends of the lamp board 20 in the length direction to limit the lamp board 20 in the installation groove 14.

[0076] At the same time, a limiting protrusion 61 is provided on the side of the end cap 60 facing the accommodating cavity 11, and limiting slots 62 are provided at both ends of the length direction of the light guide plate 30 and the reflector 40. The limiting protrusion 61 is adapted to fit within the limiting slot 62, so that when the end cap 60 is connected to the housing 10, the limiting protrusion 61 can be locked within the limiting slot 62, thereby limiting the movement of the light guide plate 30 and the reflector 40 relative to the housing 10 along the length direction.

[0077] See Figure 2 and Figure 7 The LED lamp may further include a control box 70 , a fan 80 and a battery 90 .

[0078] The control box 70 can be snap-fitted onto the housing 10. Figure 2 Of course, the control box 70 can also be detachably connected to the end cover 60, as shown in FIG. Figure 5 and Figure 7 shown.

[0079] The control box 70 is electrically connected to the light-emitting element 22 to control the on / off state of the light-emitting element 22. In this embodiment, after being connected to the end cap 60, the control box 70 can also rotate relative to the end cap 60, that is, rotate about the longitudinal axis of the housing 10, thereby meeting different application scenarios.

[0080] The fan 80 is installed in the accommodating chamber 11 and is attached to the bottom wall of the accommodating chamber 11. It is located on the side of the reflector 40 facing away from the light guide plate 30. At the same time, the bottom wall of the accommodating chamber 11 is provided with a heat dissipation hole 16 for passing through. The heat dissipation hole 16 is arranged directly opposite the fan 80, so that the air in the accommodating chamber 11 can flow out of the accommodating chamber 11 through the heat dissipation hole 16 under the drive of the fan 80. It should be noted that since the light-emitting element 22 generates a large amount of heat when it is working, the temperature in the accommodating chamber 11 will rise, thereby affecting the use of the LED lamp. Therefore, the fan 80 is provided to cool the space in the accommodating chamber 11 to ensure that the LED lamp can be used continuously.

[0081] The battery 90 is installed in the accommodating cavity 11 and is electrically connected to the light emitting element 22 to provide power to the light emitting element 22. In this embodiment, the battery 90 can also provide power to the control box 70 and the fan 80, thereby facilitating the use of the LED lamp.

[0082] In summary, a housing 11 is provided on the shell 10, and a light emitting surface 12 is formed on the surface of the shell 10. The lamp board 20 is installed in the housing cavity 11 and is located on the side wall of the housing cavity 11. The light guide plate 30 is installed in the housing cavity 11, and the light guide plate 30 is arranged opposite the light emitting surface 12. The reflector 40 is installed in the housing cavity 11 and is located on the side of the light guide plate 30 away from the light emitting surface 12. The surface of the reflector 40 is provided with a reflecting surface 41, and faces the light emitting surface 12, so that the light emitted by the light-emitting component 22 can be guided by the light guide plate 30, and after being reflected by the reflecting surface 41, the light is emitted from the housing cavity 11 from the light emitting surface 12, so that the LED lamp can emit uniform light to meet the lighting requirements of different scenes.

[0083] At the same time, a plurality of light-emitting components 22 are provided on the board body 21 of the lamp board 20, and the light-emitting components 22 include RGB LED lamp beads 23 and / or white light LED lamp beads 24, and the RGB LED lamp beads 23 include red light chips 231, green light chips 232 and blue light chips 233, and the white light LED lamp beads 24 include warm white light chips 241 and / or cold white light chips 242, so that the LED can emit light of different colors or different color temperatures, thereby meeting different usage requirements.

[0084] While the present invention has been described with reference to several exemplary embodiments, it should be understood that the terms used are illustrative and exemplary rather than restrictive. Since the present invention can be embodied in a variety of forms without departing from the spirit or essence of the invention, it should be understood that the above-described embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope of the appended claims. Therefore, all changes and modifications that fall within the scope of the claims or their equivalents are intended to be covered by the appended claims.
