[0030] As a lighting tool, light-emitting devices are widely used in daily life. For example, a stick light is usually a long hard lamp body, which can be stretched and bent as needed to adjust the light angle, so it is more suitable for scenes that require fine lighting, such as reading, writing, painting, etc. The light of the stick light is relatively concentrated and suitable for local lighting. In the prior art, a light-emitting device provided with a baffle is a lighting device with a detachable baffle design, and the baffle can be used to control the range and shape of the light. The main function of the baffle is to control the range and shape of the light. By adjusting the expansion angle of the baffle, the range of the light irradiation can be clearly perceived, so that the light form is richer. In addition, the baffle can also prevent direct light, reduce unnecessary interference of light on the subject, and improve the shooting effect. At present, the light-emitting devices with baffles on the market are generally single-layer structures. In this way, the baffle is small and cannot block light over a large area, which makes it difficult to meet the user's needs for different scenes.

[0031] See also Figure 1 to Figure 7In order to solve the above problems, the embodiment of the present application provides a light-emitting device 10 with a double-layer retractable baffle, including a lamp body 20, a first baffle 30, a second baffle 40 and an elastic connection component 50, wherein the first baffle 30 is rotatably connected to the lamp body 20; the first baffle 30 can be rotated relative to the lamp body 20 to switch between a first retracted state and a first expanded state, and when the first baffle 30 is in the first expanded state, the first baffle 30 is inclined relative to the light emitting surface of the lamp body 20; the elastic connection component 50 is rotatably connected to the first baffle 30 and the second baffle 40 respectively, the second baffle 40 is arranged parallel to the first baffle 30, and the second baffle 40 can be rotated in a plane parallel to the first baffle 30 through the elastic connection component 50 to switch between the second retracted state and the second expanded state relative to the first baffle 30.

[0032] See also Figures 1 to 9 In the light-emitting device 10 with a double-layer retractable baffle provided in the present application, it includes a lamp body 20, a first baffle 30, a second baffle 40 and an elastic connection component 50. The lamp body 20 has a lighting function in the light-emitting device 10 with a double-layer retractable baffle. The lamp body 20 can be a relatively long hard lamp body 20, and the lamp body 20 is connected to the first baffle 30. In some embodiments, the first baffle 30 is rotatably connected to the lamp body 20, and two first baffles 30 are respectively connected at the two relatively long ends of the lamp body 20. The lamp body 20 includes a lamp group and a control module, and the control module is connected to the lamp group. The lamp group can be composed of different numbers of LED lamp bead arrays arranged in combination to form a light source of the light-emitting device. In some embodiments, the first baffle 30 is rotatably connected to the second baffle 40, wherein the first baffle 30 can rotate relative to the lamp body 20 to switch between a first folded state and a first extended state, when the first baffle 30 is in the first extended state, the first baffle 30 is inclined relative to the light emitting surface of the lamp body 20, the second baffle 40 and the first baffle 30 are arranged parallel, and the second baffle 40 can rotate in a plane parallel to the first baffle 30 through the elastic connection component 50 to switch between a second folded state and a second extended state relative to the first baffle 30. Specifically, when the second baffle 40 and the first baffle 30 overlap each other, the second baffle 40 is in the second folded state relative to the first baffle 30, and when the second baffle 40 is fully extended, the second baffle 40 is in the second extended state relative to the first baffle 30. The elastic connection component 50 is rotationally connected to the first baffle 30 and the second baffle 40 respectively. When the second baffle 40 rotates parallel to the plane of the first baffle 30, the elastic connection component 50 generates corresponding force to cooperate with the second baffle 40 to achieve switching between the second folded state and the second unfolded state.

[0033] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6In some embodiments, the first baffle 30 and the second baffle 40 may be made of opaque material. The baffle made of opaque material can completely block light and is suitable for scenes where the light intensity needs to be completely controlled. Opaque materials can effectively block light and ensure that light does not leak, which is suitable for environments where complete light blocking is required. In some embodiments, the first baffle 30 and the second baffle 40 may be made of translucent material. The baffle made of translucent material can weaken the light brightness and control the light distribution, which is suitable for scenes where the light intensity and distribution need to be adjusted. Translucent materials allow part of the light to pass through, which can create a soft light effect, which is suitable for scenes where soft lighting or specific light and shadow effects are required. Opaque materials are suitable for situations where complete light blocking is required, while translucent materials are suitable for scenes where the light intensity and distribution need to be adjusted. During use, the user can select or replace the material of the first baffle 30 and the second baffle 40 according to the actual specific use needs and environment, which can increase the diversity of the use scenarios of the light emitting device 10 with a double-layer retractable baffle.

[0034] See also Figure 1 , Figure 4 , Figure 5 , Figure 7 , Figure 8 and Fig. 9In some embodiments, the elastic connection assembly 50 includes a connecting rod 51 and a torsion spring 52. The connecting rod 51 is used to convert rotational motion into linear motion or convert linear motion into rotational motion. In the present application, the connecting rod 51 can make the second baffle 40 perform linear motion by its own rotation, that is, the second baffle 40 can switch between the second folded state and the second unfolded state relative to the first baffle 30 under the action of the elastic connection assembly 50. Specifically, the two ends of the connecting rod 51 are respectively rotatably connected to the first baffle 30 and the second baffle 40, and the two ends of the torsion spring 52 are respectively connected to the first baffle 30 and the second baffle 40; in the second unfolded state and the second folded state, the torsion spring 52 maintains a good pre-stressed elastic force, so that the second baffle 40 and the first baffle 30 will not be loosened or separated. In some embodiments, the connecting rod 51 can be made of aluminum, and the connecting rod 51 can also be made of stainless steel, wherein the connecting rod 51 made of stainless steel has good rust resistance. The torsion spring 52 is a cylindrical helical spring that bears torque. It mainly works by twisting or rotating a soft elastic material with high toughness, so that it has huge mechanical energy. The working principle of the torsion spring 52 is based on the principle of lever, which stores energy by twisting or rotating the elastic material and releases it when needed. In some embodiments, the torsion spring 52 is arranged in an isosceles triangle shape. The isosceles triangle arrangement makes the first baffle 30 and the second baffle 40 balanced, and the elastic force received by the second baffle 40 and the first baffle 30 is uniform, so that the light-emitting device 10 with a double-layer retractable baffle is more stable and reliable as a whole. In some embodiments, one end of the torsion spring 52 is clamped between one end of the connecting rod 51 and the first baffle 30, and the other end of the torsion spring 52 is clamped between the other end of the connecting rod 51 and the second baffle 40. The end of the torsion spring 52 is fixed to other components. When the other components rotate around the center of the torsion spring 52, the torsion spring 52 pulls them back to the initial position to generate torque or rotational force. The torsion spring 52 can store and release angular energy or statically fix a device by rotating the lever arm around the central axis of the torsion spring 52. With the cooperation of the torsion spring 52 and the connecting rod 51, the movement between the double-layer baffles can be realized to achieve the folding and retracting effect of the light-emitting device 10 with the double-layer retractable baffles.

[0035] Continue reading Figure 1 , Figure 4 , Figure 5 , Figure 7 , Figure 8 and Fig. 9In some embodiments, three mounting holes 41 are provided on one side of the second baffle plate 40 close to the first baffle plate 30, and the connecting lines between the three mounting holes 41 are distributed in an isosceles triangle. The isosceles triangle distribution enables the positions of the three mounting holes 41 to achieve three-point fixed torsion spring and clamping of the connecting rod 51. In some embodiments, boss buckles 511 are provided on the opposite sides of the connecting rod 51, and the connecting rod 51 is riveted and connected to the first baffle plate 30 and the second baffle plate 40 respectively through the two boss buckles 511. Bosses are provided on both sides of the connecting rod 51 to facilitate the installation of the connecting rod 51 into the first baffle plate 30 and the second baffle plate 40. After the connecting rod 51 is installed in the first baffle plate 30 and the second baffle plate 40, the baffle plates are fixed and clamped by riveting, so that the second baffle plate 40 and the first baffle plate 30 will not be loosened or separated. The boss buckles 511 facilitate riveting and forming undercuts after assembly to clamp the second baffle plate 40 and the first baffle plate 30. In one embodiment, the connecting rod 51 and the torsion spring 52 are both connected to the mounting hole 41. In the second embodiment, only the connecting rod 51 is connected to the mounting hole 41. In the third embodiment, only the torsion spring 52 is connected to the mounting hole 41.

[0036] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6In some embodiments, the elastic connection component 50 adopts a variety of assembly methods of the torsion spring 52 and the connecting rod 51. The user can assemble the elastic connection component 50 according to the parameters such as the size of the first baffle 30 and the second baffle 40. For example, the connecting rods 51 on both sides can be used in conjunction with the middle torsion spring 52 to realize the mode of parallel connection 51 rotation movement. The connecting rods 51 on both sides rotate, thereby driving the second baffle 40 to move linearly relative to the first baffle 30. This combination is suitable for the scene where the second baffle 40 is relatively small. In the process of the elastic connection component 50 driving the second baffle 40 to move relative to the first baffle 30, the torsion spring 52 can withstand torque, store energy by twisting or rotating the elastic material, and release it when needed. In this process, the connecting rod 51 converts the rotational motion into linear motion, and the torsion spring 52 and the connecting rod 51 cooperate to realize the rotational motion between the first baffle 30 and the second baffle 40 to realize the folding and retracting function of the light-emitting device 10 with a double-layer retractable baffle. In other embodiments, a combination of two torsion springs 52 and one connecting rod 51 can be used, wherein the connecting rod 51 is arranged on the side, one torsion spring 52 is arranged on the side, and the other torsion spring 52 is arranged in the middle, so as to realize the rotational movement of the parallel connecting rod 51. A combination of three torsion springs 52 can also be used, that is, a structure in which torsion springs 52 are arranged at three mounting holes 41. In this embodiment, the push-pull force generated by the elastic connection component 50 is relatively large, which is suitable for clamping the second baffle 40 which is larger and heavier than the above two embodiments. Different combinations of torsion springs 52 and connecting rods 51 are suitable for different usage scenarios. Generally, an elastic connection component 50 with 1 to 2 torsion springs 52 is suitable for occasions where the second baffle 40 is relatively small and light, and an elastic connection component 50 with three torsion springs 52 is suitable for occasions where the second baffle 40 is relatively large and heavy. The various forms of the combination of torsion springs 52 and connecting rods 51 are fixed with screws 62, which greatly facilitates the user to disassemble and reassemble the light-emitting device 10 with a double-layer retractable baffle. The combination of the torsion spring 52 and the connecting rod 51 can be matched according to user needs, and will not be described one by one here. In some embodiments, five mounting holes 41 are provided on the side of the second baffle plate 40 close to the first baffle plate 30, and the connecting lines between the five mounting holes 41 are distributed in an isosceles triangle. The connecting rod 51 and / or the torsion spring 52 are connected to the mounting holes 41. In this embodiment, a combination structure of a larger number of connecting rods 51 or torsion springs 52 can be set according to user needs to achieve the folding and retracting function of the light-emitting device 10 with a double-layer retractable baffle, so that the light-emitting device 10 with a double-layer retractable baffle meets the user's usage needs in different scenarios.

[0037] See also Figure 1 , Figure 4 , Figure 5 , Figure 7 , Figure 8 and Fig. 9In some embodiments, the first baffle 30 and the second baffle 40 are both provided with a pin 61, and the torsion spring 52 and the connecting rod 51 are rotatably connected to the pin 61. In other embodiments, only the torsion spring 52 is connected to the pin 61, or only the connecting rod 51 is rotatably connected to the pin 61. A screw 62 is fixed to the pin 61, and in some embodiments, the torsion spring 52 and the connecting rod 51 are clamped between the pin 61 and the screw 62. In other embodiments, only the torsion spring 52 is clamped between the pin 61 and the screw 62, or only the connecting rod 51 is clamped between the pin 61 and the screw 62. In some embodiments, the pin 61 can be an aluminum pin or a stainless steel pin. The stainless steel pin 61 has good rust resistance and is suitable for use in a humid or corrosive environment. The torsion spring 52 is fixed integrally with the first baffle 30 and the second baffle 40 by means of the pin 61 and the screw 62, so as to form a better integrity with each other and ensure that the light emitting device 10 with double-layer retractable baffles has good strength and rigidity.

[0038] See also Figure 7 , Figure 8 and Fig. 9 In some embodiments, a slot is provided on the side of the pin 61, and the end of the torsion spring 52 has a C-shaped notch structure 521. The torsion spring 52 is inserted into the slot through the C-shaped notch structure 521 to achieve fixation between the torsion spring 52 and the pin 61. The C-shaped notches at the two corners of the torsion spring 52 can be forcibly pressed into the slot of the aluminum pin. In some embodiments, the diameter of the steel wire of the torsion spring 52 is set to 8 mm. Since the diameter of the steel wire of the torsion spring 52 is 8 mm, the torsion spring 52 has good rigidity to ensure that the torsion spring 52 and the pin 61 are not easily loosened by force. In some embodiments, a limiting column 31 is provided on the side of the first baffle 30 close to the second baffle 40. In the second folded state, the limiting column 31 abuts against the edge of the second baffle 40 close to the lamp body 20. The limiting column 31 can be used to limit the starting position of the rotation of the second baffle 40. In some embodiments, a lug 42 is provided on an edge of the second baffle 40 away from the lamp body 20. In the second folded state, the lug 42 protrudes from the first baffle 30. The lug 42 protrudes and is exposed to facilitate the user to operate the second baffle 40 to move.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
