DETAILED DESCRIPTION

[0039] The scheme of the embodiment of the present application is described in detail below in conjunction with the drawings of the specification.

[0040] In the following description, for the purpose of explanation rather than limitation, specific details such as specific system structures, interfaces, and technologies are provided to facilitate a thorough understanding of the present application.

[0041] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0042] The terms "first", "second", "third" in this application are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Thus, the features defined as "first", "second", "third" can expressly or implicitly include at least one of the features. In the description of this application, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined. In the embodiments of this application, all directional indications (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication also changes accordingly. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the steps or units listed, but optionally also includes steps or units that are not listed, or optionally also includes other steps or units inherent to these processes, methods, products or devices.

[0043] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0044] The embodiment of the present disclosure provides a bookmark light. Figure 1 and Figure 2 The bookmark light includes a light-emitting panel 1 and a light-shielding film 2. The light-emitting panel 1 has a light-emitting surface 11 and a backlight surface 12 relative to each other. The light-shielding film 2 is movably connected to the light-emitting panel 1, and the light-shielding film 2 includes a light-shielding portion 21. The light-shielding portion 21 can switch between a first state and a second state; when the light-shielding portion 21 is in the first state, the light-shielding portion 21 is substantially parallel to the light-emitting panel 1; when the light-shielding portion 21 is in the second state, at least part of the light-shielding portion 21 is cross-set with the light-emitting surface 11 to block the side light of the light-emitting panel 1. In this way, when the user uses the bookmark light, the light-shielding portion 21 is operated to make the light-shielding portion 21 in the second state, and the light-shielding portion 21 blocks the side light of the light-emitting panel 1, reduces the impact of the side light of the light-emitting panel 1 on the surrounding people, and also reduces the impact of the surrounding ambient light on the user. Compared with the existing portable reading lights, the light-shielding film 2 provided in the bookmark light can reduce the impact on the surrounding people, thereby solving the relatively serious problem that the side light of the portable reading light irradiates the surrounding people.

[0045] When the light shielding portion 21 is in the first state, the light emitting panel 1 and the light shielding film 2 are approximately horizontal thin plates, and can be used as a bookmark.

[0046] The shading portion 21 is substantially parallel to the light emitting panel 1, which means that the angle between the shading portion 21 and the light emitting panel 1 is 0-10°, for example, the angle can also be 0-5°. When the angle is 0°, it means that the shading portion 21 is parallel to the light emitting panel 1.

[0047] The light shielding portion 21 is arranged crosswise with the light emitting surface 11, which means that Figure 2 The angle A between the light shielding portion 21 and the light emitting surface 11 is shown to be greater than 0° and less than 180°, so that the light shielding portion 21 can block the side light of the light emitting panel 1. For example, the angle A can be between 10° and 170°, and for another example, the angle A is 120°.

[0048] The first state and the second state refer to two different states of the light shielding portion 21 relative to the light emitting panel 1. Since the light shielding film 2 is movably connected to the light emitting panel 1, the light shielding portion 21 can be switched between the first state and the second state.

[0049] In some examples, the light emitting panel 1 is a device capable of emitting light. For example, the light emitting panel 1 is a flexible surface light source. Figure 3 The light emitting panel 1 may include a stacked flexible substrate 13, a circuit layer, a reflective layer 14, a light emitting device layer 15, a fluorescent packaging layer 16 and a diffusion layer 17. In this way, the light emitted by the light emitting device layer 15 passes through the fluorescent packaging layer 16 and the diffusion layer 17 in sequence, so that the light on the light emitting surface 11 is more uniform.

[0050] The material of the flexible substrate 13 can be any one of polyimide, triacetate film, etc. The flexible substrate 13 can also be made of a metal sheet with good bending performance, such as copper or aluminum, etc., or a glass sheet.

[0051] The circuit layer may be electrically connected to the light emitting device 152 , so as to provide direct current or alternating current to the light emitting device 152 , so that the light emitting device 152 emits light.

[0052] The existing portable reading lamp only includes one light-emitting device (such as an LED lamp bead). When the portable reading lamp is used, the illumination provided by the portable reading lamp is small, the illumination uniformity is cross-shaped, and the eye damage is relatively serious. Therefore, in the present embodiment, the light-emitting device layer 15 includes a plurality of light-emitting devices 152, and the plurality of light-emitting devices 152 emit light, so that the illumination of the light-emitting panel 1 is much greater than the illumination of the existing portable reading lamp, and the illumination uniformity is far greater than the illumination uniformity of the existing portable reading lamp, which is conducive to reading and less harmful to the eyes.

[0053] A plurality of light emitting devices 152 may be arranged at intervals on the reflective layer 14. The reflective layer 14 can reflect the light of the light emitting device 152, thereby improving the light extraction efficiency of the light emitting panel 1. The light emitting device 152 may, for example, use a miniLED chip, specifically a monochrome chip, such as a blue chip or a purple chip. The light emitting device 152 may use a chip without a substrate, thereby enhancing the flexibility of the light emitting panel 1. The light emitting device 152 includes a first light emitting diode, a second light emitting diode, and a third light emitting diode for emitting light of different colors, and the first light emitting diode, the second light emitting diode, and the third light emitting diode are alternately arranged on the reflective layer 14. Among them, the first light emitting diode, the second light emitting diode, and the third light emitting diode may be used to emit red light, green light, and blue light, respectively.

[0054] The material of the reflective layer 14 is reflective ink, white oil, silver or aluminum. The reflective layer 14 can be bent and arranged on the circuit layer. The reflective layer 14 forms a first contact channel, and one electrode of the light emitting device 152 is electrically connected to the circuit layer through the first contact channel; the reflective layer 14 forms a second contact channel, and the other electrode of the light emitting device 152 is electrically connected to the circuit layer through the second contact channel.

[0055] The fluorescent encapsulation layer 16 can protect the circuit layer and the light-emitting device layer 15, and physically isolate them from other layers above the fluorescent encapsulation layer 16 or the outside world. The fluorescent encapsulation layer 16 includes a mixture of fluorescent powder and encapsulation glue; the fluorescent powder mixed in the encapsulation glue can make the fluorescent encapsulation layer 16 have a color conversion function. The fluorescent powder can absorb the light of the light-emitting device 152 and then convert it into light of a specific wavelength, thereby realizing the color conversion function. The fluorescent powder can be a fluorescent powder emitting a spectral wavelength of 500-600 nanometers, specifically 520nm, 550nm or 580nm. The mass ratio of encapsulation glue to fluorescent powder is between 1:0.3 and 1:1, so that the fluorescent encapsulation layer 16 has a color conversion function and reduces the impact on the encapsulation function of the fluorescent encapsulation layer 16.

[0056] The diffusion layer 17 is used to correct the light into a uniform surface light source, and can diffuse the light emitted by the light emitting device layer 15, thereby improving the uniformity of the light.

[0057] The light emitting panel 1 may have one light emitting surface 11, or for example, the light emitting panel 1 may have multiple light emitting surfaces 11. In this article, the light emitting panel 1 having one light emitting surface 11 is used as an example for explanation. The light emitting surface 11 refers to the surface of the light emitting panel 1 used for emitting light, and the backlight surface 12 is the non-light emitting surface of the light emitting panel 1. The light emitting surface 11 may be the surface of the diffusion layer 17 on the side away from the circuit layer, and the backlight surface 12 may be the surface of the flexible substrate 13 on the side away from the circuit layer.

[0058] For some examples, see Figure 3The bookmark light also includes a control circuit, which is electrically connected to the light-emitting panel 1; the light-emitting panel 1 includes a light-emitting device layer 15, and the light-emitting device layer 15 includes a plurality of light-emitting device areas 151. The control circuit controls the plurality of light-emitting device areas 151 to emit light independently. The control circuit can be used to make the light-emitting device areas 151 in different areas emit light, and can control the corresponding light-emitting device areas 151 to emit light in response to different application scenarios. The light-emitting device area 151 may include at least one light-emitting device 152.

[0059] Taking the light emitting device layer 15 including two light emitting device areas 151 as an example, only one light emitting device area 151 is turned on, so that the bookmark light is closer to the book, and the illumination of the light emitting panel 1 is small, which is suitable for reading at night in the dormitory and reading on public transportation. When the two light emitting device areas 151 are turned on, the light emitting panel 1 is far away from the book, for example, in accordance with the national standard (40cm); at this time, the illumination of the light emitting panel 1 is large, and it can be used as a desk lamp.

[0060] The control circuit may be a multi-speed switch circuit, and the multi-speed switch is set in one-to-one correspondence with the multiple light-emitting device areas 151; the multi-speed switch is operated so that the multiple light-emitting device areas 151 emit light independently. The control circuit may also be a controller, and the controller is used to make the multiple light-emitting device areas 151 emit light independently. The control circuit may also adjust the illumination, color temperature, spectrum, etc. of the light-emitting panel 1. The control circuit has multiple mode gears. In any mode gear, the light-emitting panel 1 emits light corresponding to the mode gear, and the multiple mode gears make the light emitted by the light-emitting panel 1 different. For example, the multiple gears may include a sleeping gear, a wakefulness gear, and a normal gear.

[0061] For some examples, see Figure 4 The light-emitting panel 1 includes a plurality of light-emitting sub-panels 19, and two adjacent light-emitting sub-panels 19 are folded and connected. The size of the light-emitting panel 1 can be changed, and it is convenient to carry after being folded. The number of light-emitting sub-panels 19 can be selected according to different application scenarios, thereby expanding the scope of application.

[0062] In some examples, the light shielding film 2 may be a structure capable of blocking all light from passing through, that is, the light transmittance of the light shielding film 2 is 0. In other examples, the light shielding film 2 may be a structure capable of blocking most light from passing through, and allowing a small portion of light to pass through; that is, the light transmittance of the light shielding film 2 is less than 50% and greater than 0; for example, the light transmittance of the light shielding film 2 is 5%.

[0063] In some examples, the shading film 2 may be a single-layer structure. For example, the shading film 2 may be a metal foil, such as copper foil, aluminum foil, etc. In other examples, for example, the shading film 2 may also be a plurality of structures; the shading film 2 may include a base layer and a coating layer, the base layer includes a first surface and a second surface relative to each other; the coating layer is arranged on the first surface and / or the second surface. The base layer may be a diaphragm, cloth, etc.; for example, the diaphragm is a soft diaphragm, and the cloth is a soft cloth, so that the soft diaphragm or the soft cloth can droop naturally under the action of gravity. The material of the coating layer may be a shading material, such as resin, ink, etc. Among them, the materials of the base layer and the coating layer may both be resins. In the following, when the shading film 2 is also used for reflection, the material of the coating layer may be a material having both shading and reflection functions (referred to as shading reflective material for short), for example, the shading reflective material may be a resin.

[0064] In some embodiments, see Figure 1 , the light shielding film 2 is connected to the light emitting surface 11; when the light shielding portion 21 is in the first state, the light shielding film 2 is attached to the light emitting surface 11. In this way, when the light shielding film 2 is in the first state, it plays a role in protecting the light emitting surface 11 and reducing the risk of the light emitting surface 11 being damaged by foreign objects. For example, the light shielding film 2 is attached to the light emitting surface 11, and another example is that the light shielding film 2 is electrostatically adsorbed on the light emitting surface 11.

[0065] In some embodiments, see Figure 1 and Figure 2 The light shielding film 2 is connected to the edge of the light emitting surface 11 through the hinge 3. The entire light shielding film 2 serves as the light shielding portion 21. The light shielding film 2 is easily installed on the edge of the light emitting surface 11 by means of the hinge connection. Alternatively, see Figure 5 and Figure 6 The light shielding film 2 further includes a first connecting portion 22 fixed to the edge of the light exiting surface 11, and the light shielding portion 21 and the first connecting portion 22 are foldably connected; the first connecting portion 22 ensures the stability and reliability of the light shielding film 2, and the foldable connection enables the light shielding portion 21 to flexibly adapt to the needs of different angles. For example, the light shielding portion 21 and the first connecting portion 22 are an integrated structure.

[0066] In some examples, the light emitting surface 11 may include a light emitting area and a non-light emitting area, and the non-light emitting area is arranged on at least one side of the light emitting area, for example, the non-light emitting area is arranged around the light emitting area; in this case, the edge of the above-mentioned light emitting surface 11 is the non-light emitting area. The non-light emitting area may be a frame of the light emitting panel 1. In other examples, the light emitting surface 11 is the entire light emitting area, that is, there is no non-light emitting area, and the edge of the light emitting surface 11 is the portion of the light emitting surface 11 close to its edge. In some examples, the number of the light shielding films 2 may be one or more.

[0067] In some embodiments, see Figure 7 and Figure 8, the light shielding film 2 further includes a second connecting portion 23 fixed to the backlight surface 12, and the light shielding portion 21 and the second connecting portion 23 are foldably connected. When the light shielding portion 21 is in the first state, the light shielding portion 21 and the second connecting portion 23 are not folded, so that the light shielding portion 21 and the second connecting portion 23 are arranged substantially parallel to the light emitting panel 1 as a whole. When the light shielding portion 21 is in the second state, the light shielding portion 21 and the second connecting portion 23 are folded, and the light shielding portion 21 is folded from the backlight surface 12 to one side of the light emitting surface 11, and the portion of the light shielding portion 21 that exceeds the light emitting surface 11 is used to block the side light of the light emitting panel 1.

[0068] In some embodiments, see Fig. 9 , the light shielding film 2 covers the entire backlight surface 12 and extends beyond the light emitting panel 1; the portion of the light shielding film 2 located on the backlight surface 12 forms a second connecting portion 23, and the portion of the light shielding film 2 extending beyond the light emitting panel 1 forms a light shielding portion 21. In this way, the light shielding film 2 protects the backlight surface 12 and reduces the risk of the backlight surface 12 being damaged by foreign objects.

[0069] In some embodiments, see Fig. 9 , the first side 4 of the second connection part 23 is flush with the first side 4 of the light emitting panel 1; or, the first side 4 of the second connection part 23 exceeds the first side 4 of the light emitting panel 1, and the first side 4 of the second connection part 23 is used to prevent glare. The light shielding film 2 extends beyond the light emitting panel 1 on all sides except the first side 4 of the light emitting panel 1 to form a light shielding part 21. In this way, when the bookmark light is used, the light shielding part 21 only leaks out of the first side 4 of the light emitting panel 1. When the user faces the first side 4, the structure surrounded by the user and the light shielding part 21 blocks all the side light of the light emitting panel 1, and does not affect other people.

[0070] In some embodiments, see Fig.10 The shading portion 21 has a cutout at the corner corresponding to the light emitting panel 1, and the cutout divides the shading portion 21 into a plurality of sub-shading portions 21; when the shading portion 21 is in the second state, the plurality of sub-shading portions 21 cooperate to form a barrel-shaped body with an opening on the side. In this way, the opening is set so that there are no wrinkles between the plurality of sub-shading portions 21; when the shading portion 21 is in the second state, the shading portion 21 is more beautiful. The opening is located on the same side as the first side 4.

[0071] In some examples, the light emitting panel 1 includes a first side 4 and a plurality of second sides connected in sequence; since the first side 4 of the light emitting panel 1 is aligned with the first side 4 of the second connecting portion 23, the plurality of light shielding portions 21 are arranged in one-to-one correspondence with the plurality of second sides of the light emitting panel 1. For example, the light emitting panel 1 is a quadrilateral, and three light shielding portions 21 are arranged in one-to-one correspondence with the three second sides of the light emitting panel 1.

[0072] In some embodiments, the shading film 2 includes a first shading film and a second shading film. The first shading film is connected to the edge of the light-emitting surface 11 and includes a first shading portion. When the first shading portion is in the first state, the first shading portion adheres to and covers the light-emitting surface 11. The second shading film covers the backlight surface 12 and extends beyond the light-emitting panel 1. The portion of the second shading film that extends beyond the light-emitting panel 1 forms a second shading portion. In this way, when the bookmark light is not in use, the first shading portion can protect the light-emitting surface 11, and the second shading film can protect the backlight surface 12. When the bookmark light is in use, the first shading portion and the second shading portion are both in the second state, and the first shading portion and the second shading portion can both block the side light of the light-emitting panel 1. Among them, the description of the first shading film and the second shading film can refer to the relevant description of the above-mentioned shading film 2, and will not be repeated.

[0073] In some embodiments, the light-emitting panel 1 is an N-gon, and the number of the shading portions 21 is N-1; each shading portion 21 is connected to an edge of the light-emitting surface 11; when the shading portion 21 is in the first state, multiple shading portions 21 are stacked on the light-emitting surface 11; when the shading portion 21 is in the second state, multiple shading portions 21 are arranged in cooperation to form a barrel-shaped body with an opening on the side. Wherein, N is greater than or equal to 3. For example, if N is 3, the light-emitting panel 1 is a triangle, and the number of the shading films 2 is two. For another example, if N is 4, the light-emitting panel 1 is a quadrilateral, and the number of the shading films 2 is three.

[0074] In some embodiments, when the shading portion 21 is in the first state, the shading film 2 covers the entire light-emitting panel 1, so that the shading film 2 can protect the light-emitting surface 11 or the backlight surface 12. When the shading portion 21 is in the second state, the angle A between the shading portion 21 and the light-emitting surface 11 is 90-135 degrees, which can make the illumination range of the bookmark light smaller, the light more concentrated, and the illumination range brighter.

[0075] In some embodiments, the light shielding portion 21 is a reflective sheet. In this way, the reflective sheet can also reflect the side light of the light-emitting panel 1 to increase the illumination of the light-emitting panel 1. The reflectivity of the reflective sheet is greater than 30%, for example, the reflectivity is greater than 50%, and for example, the reflectivity is greater than 90%. The reflective sheet can be a metal reflective film or an all-dielectric reflective film.

[0076] In some embodiments, the surface of the light shielding film 2 facing away from the light emitting panel 1 has a decorative pattern; or, the surface of the light shielding film 2 facing the light emitting panel 1 has a decorative pattern. In this way, the decorative pattern can be seen from the outside of the light shielding film 2, making the light shielding film 2 beautiful. The light shielding film 2 can be made of a transparent material, such as resin, or an opaque material.

[0077] In some embodiments, the shading film 2 is plastic, so that the shading portion 21 can be bent into any angle, and the user can bend or parallel the shading film 2 by operating the plastic shading film 2. Alternatively, the shading film 2 is flexible, so that the shading portion 21 can be naturally bent under the action of gravity. When the bookmark light is used, the flexible shading film 2 is in the second state under the action of gravity, so as to block the side light of the light-emitting panel 1. In some examples, the plastic shading film 2 can be a metal foil. The flexible shading film 2 can be a resin film, or a paper.

[0078] In some embodiments, the light shielding film 2 is a metal foil or a resin film.

[0079] Existing portable reading lights (such as table lamps) are relatively large in size, which takes up a lot of space. In this embodiment, the thickness of the light-emitting panel 1 is 0.2mm to 1mm, the length of the light-emitting panel 1 is 10mm to 300mm, and the width of the light-emitting panel 1 is 10mm to 300mm. In this way, due to the simple structure of the bookmark light, the size of the bookmark light can be reduced. Compared with existing portable reading lights, the bookmark light is much smaller in size, and the space occupied is also reduced accordingly. The bookmark light is very convenient to use and easy to carry. The bookmark light can be used as a bookmark clip in a book, and it makes the book less arched. The weight of the bookmark light is 10g to 50g.

[0080] In some embodiments, see Fig.11 The bookmark light also includes a power cord 6, which is fixedly electrically connected or pluggably electrically connected to the light-emitting panel 1.

[0081] The power cord 6 is fixedly electrically connected to the light emitting panel 1, so that the user does not need to find or match the power cord 6, and can directly plug it into the socket for use, which improves the convenience of use. The electrical connection between the power cord 6 and the light emitting panel 1 is highly stable, reducing the risk of poor contact or unstable connection.

[0082] The power cord 6 is plugged into the light panel 1. When the power cord 6 is damaged or aged, the user can easily remove and replace it with a new power cord 6 without replacing the entire power supply 7 device, thereby reducing maintenance costs. The detachable power cord 6 can be stored independently of the bookmark light, making the bookmark light itself more compact, so that the bookmark light can be developed in the direction of miniaturization.

[0083] For some examples, see Fig.11The power cord 6 includes a universal hose 61 and a wire 62 disposed in the universal hose 61. In this way, the universal hose 61 of the power cord 6 can also adjust the angle and height of the light-emitting panel 1 for the convenience of users. The universal hose 61 protects the wire 62 and reduces the damage to the wire 62 to extend the service life of the wire 62. The outer diameter of the universal hose 61 is 2-5mm. When the bookmark light is in use, the height adjustment range of the universal hose 61 is 8-12cm, which can make the illumination and uniformity of the book better, and will not affect the surrounding people. It is suitable for night reading in the dormitory, reading on public transportation, etc.

[0084] In some embodiments, see Fig.11 The bookmark light also includes a power supply 7; the power cord 6 is fixedly electrically connected to the power supply 7 or is pluggable electrically connected to the power supply 7.

[0085] The fixed electrical connection between the power cord 6 and the power source 7 helps ensure that all factory equipment complies with the same electrical standards and safety specifications, avoiding safety hazards caused by users replacing non-compliant power cords 6. When charging the light-emitting panel 1, users do not need to find or match a suitable power cord 6, and can directly plug it in for use, which improves the convenience and efficiency of use.

[0086] The power cord 6 is electrically connected to the power supply 7 in a plug-in manner. When the power cord 6 is damaged or aged, the user can easily remove and replace it with a new power cord 6 without replacing the entire power supply 7 device, thereby reducing maintenance costs.

[0087] In some examples, the first female connector of the light-emitting panel 1 is plug-in electrically connected to the first male connector of the power cord 6, and the second male connector of the power cord 6 is plug-in electrically connected to the second female connector of the power source 7; the power source 7 can be a power bank, an adapter, a mobile phone, a computer, etc. The first female connector is plastic-sealed in the light-emitting panel 1. For example, the first male connector and the second male connector are plastic-sealed at both ends of the universal hose 61.

[0088] In other examples, the first female connector of the light-emitting panel 1 is pluggably electrically connected to the first male connector of the power cord 6, and the power cord 6 is fixedly electrically connected to the power source 7. For example, the first male connector is plastic-sealed at one end of the universal hose 61, and the other end of the universal hose 61 is fixedly connected to the power source 7, so that the power cord 6 and the power source 7 are integrated.

[0089] In other examples, the first female connector of the light-emitting panel 1 is fixedly electrically connected to the first male connector of the power cord 6, and the second male connector of the power cord 6 is pluggably electrically connected to the second female connector of the power supply 7; the power supply 7 can be a power bank, an adapter, a computer, etc. For example, one end of the universal hose 61 is fixedly connected to the light-emitting panel 1, so that the power cord 6 and the light-emitting panel 1 are integrated; the second male connector is plastic-sealed at the other end of the universal hose 61.

[0090] In other examples, the first female connector of the light-emitting panel 1 is fixedly electrically connected to the first male connector of the power line 6 , and the second male connector of the power line 6 is fixedly electrically connected to the second female connector of the power source 7 .

[0091] For example, when the bookmark light is plugged into the power cord 6 and the power supply 7, the light panel 1 of the bookmark light emits light. For another example, the bookmark light also includes a battery, which is charged by the power cord 6 and the power supply 7, and the bookmark light emits light by the electricity provided by the battery.

[0092] For example, the universal hose 61 can be used to fix the bookmark light so as to facilitate reading. For another example, the bookmark light also includes a clamping mechanism, such as a clamping mechanism to fix the bookmark light. The clamping structure can be a clip or the like.

[0093] The outer diameter of the universal hose 61 is 1.5mm to 4.5mm, and the length of the universal hose 61 is 10mm to 50mm. This makes the size of the universal hose 61 small; even if the universal hose 61 is fixedly connected to the light-emitting panel 1, the size of the bookmark light does not increase much, and it can also be clamped in a book and used as a bookmark. For example, the outer diameter of the universal hose 61 is 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4.5mm, etc., and the length of the universal hose 61 is 10mm, 12mm, 13mm, 15mm, 17mm, 18mm, 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, 50mm, etc.

[0094] The power cord 6 is fixedly electrically connected to the power supply 7, the length of the power supply 7 is 15mm-100mm, the width of the power supply 7 is 15mm-100mm; the thickness of the power supply 7 is 10mm-20mm. This makes the size of the power supply 7 smaller; even if the universal hose 61, the power supply 7 and the light-emitting panel 1 are fixedly connected, the size of the bookmark light does not increase much, and it can also be clamped in the book as a bookmark. For example, the length of the power supply 7 is 15mm, 20mm, 30mm, 40mm, 50mm, 70mm, 100mm, etc., the width of the power supply 7 is 15mm, 20mm, 30mm, 40mm, 50mm, 70mm, 100mm, etc.; the thickness of the power supply 7 is 10mm, 12mm, 14mm, 15mm, 17mm, 18mm, 19mm, 20mm, etc. The power supply 7 is provided with a clip, which is used to facilitate the bookmark light to be clamped on the book for the convenience of user reading. The clip is a conventional technology in this field and will not be repeated. For example, the clip is detachably connected to the power source, or fixedly connected to the power source. The clip can be connected to the power source via bolts, adhesives, etc.
