Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the described features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0029] The existing stick lights have a single light output mode and uneven light output, which affects the user experience. Therefore, a double-sided LED video light is proposed to solve the above problems.

[0030] The scheme is further illustrated by the following examples:

[0031] Figure 1 It is a schematic diagram of a double-sided LED movie light according to an embodiment of the present invention. Figure 2 yes Figure 1 A schematic cross-sectional view of a double-sided LED cinema light. Figure 3 yes Figure 1 Schematic diagram of the exploded view of the double-sided LED cinema light.

[0032] See also Figure 1 、 Figure 2 and Figure 3 The double-sided LED film and television light of this embodiment can be used as a fill light device such as a stick light.

[0033] Specifically, the LED movie light using a double-sided light source may include a housing 10 , a light board 20 , a light guide plate 30 and a reflective plate 40 .

[0034] 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.

[0035] Two light boards 20 are provided, and both are mounted within the accommodating cavity 11. Each light board 20 includes 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 two light boards 20 are located on opposite sides of the accommodating cavity 11, and the light-emitting elements 22 on the two light boards 20 are arranged opposite each other.

[0036] The light guide plate 30 is installed in the accommodating cavity 11 and is located between the two light boards 20. The two opposing sides of the light guide plate 30 are aligned with the light-emitting components 22 on the two light boards 20, respectively, so that light emitted by the light-emitting components 22 can enter the light guide plate 30. At the same time, a light guide surface 31 is formed on one side of the light guide plate 30, and the light guide surface 31 is arranged toward the light emitting surface 12. This allows light emitted by the light-emitting components 22 to be guided by the light guide plate 30 and then emitted from the light guide plate 30 through the light guide surface 31.

[0037] 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.

[0038] Since there are two light boards 20, the two light boards 20 are located on both sides of the light emitting surface 12, and the light emitted by the light-emitting part 22 on the light board 20 is guided by the light guide plate 30 and then reflected by the reflective plate 40, so that the light is emitted from the light guide surface 31 and the light emitting surface 12, thereby making the light emitted by the LED movie light uniform and improving the user experience.

[0039] Figure 4 yes Figure 1 Schematic diagram of the two light panels of the LED cinema light. Figure 5 yes Figure 1 Another schematic diagram of the two light panels of the LED cinema light. Figure 6 yes Figure 1 Another schematic diagram of the two light panels of the LED cinema light.

[0040] See Figure 4 Of the two light boards 20, the light-emitting components 22 on one light board 20 are RGB LED lamp beads 23, while 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, green, and blue light chips 231, 232, and 233 arranged along the width of the board 21, while the white 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 from 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 cinema light to emit a richer light, thereby meeting the needs of different scenarios and improving the user experience.

[0041] See Figure 5 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 chip 231, a green chip 232, and a blue chip 233 arranged along the width of the board 21. Furthermore, on both light boards 20, the red chips 231, green chips 232, and blue 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 cinema lights to emit a richer light pattern, thus meeting the needs of different scenarios and improving the user experience.

[0042] See Figure 6The light-emitting elements 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 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. 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 cinema lights to emit a richer light, thereby meeting the needs of different scenes and improving the user experience.

[0043] See Figure 2 and Figure 3 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.

[0044] 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.

[0045] In this embodiment, 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.

[0046] 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.

[0047] See Figure 2 and Figure 3 The housing 10 may include a main body 52 and a soft cover 50

[0048] 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.

[0049] In this embodiment, the diffuser 50 is used as a light-transmitting cover and is used to soften the light. Specifically, the light-emitting surface 12 is formed on the diffuser 50, so that the light passes through the diffuser 50 and is emitted out of the accommodating cavity 11, and the light becomes soft.

[0050] 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.

[0051] 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.

[0052] See Figure 1 and Figure 3 The double-sided LED video light may further include two end covers 60 .

[0053] The two end caps 60 are connected to the ends of the housing 10 in the longitudinal direction, thereby forming the longitudinal side walls of the accommodating cavity 11. In this embodiment, when the end caps 60 are connected to the ends of the housing 10 in the longitudinal direction, the end caps 60 can abut against the ends 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.

[0054] In this embodiment, when the two end covers 60 are respectively connected to the two ends of the housing 10 in the length direction, the end covers 60 can push against the ends of the lamp board 20 in the length direction to restrict the lamp board 20 in the installation groove 14.

[0055] 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.

[0056] See Figure 2 and Figure 3 The double-sided LED video light may further include a control box 70 , a fan 80 and a battery 90 .

[0057] The control box 70 is detachably connected to the end cap 60 and 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.

[0058] 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 opposite the fan 80, so that the air in the accommodating chamber 11 flows 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 component 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 movie light. Therefore, the fan 80 is provided to cool the space in the accommodating chamber 11 to ensure that the LED movie light can be used continuously.

[0059] 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 movie light.

[0060] 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. Two lamp boards 20 are provided, and both lamp boards 20 are installed in the housing cavity 11 and are located on opposite sides of the housing cavity 11. The light guide plate 30 is installed in the housing cavity 11 and is located between the two lamp boards 20. 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 reflective 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 reflective surface 41, the light is emitted from the housing cavity 11 from the light emitting surface 12, so that the LED film and television light can emit uniform light and meet the lighting requirements of different scenes.

[0061] 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.
