[0033] In order to provide a further understanding of the purpose, structure, features, and functions of the present invention, the present invention is described in detail below with reference to the embodiments.

[0034] Please refer to Figures 1 and 2 , Figure 1 FIG. 1 shows a side view of a clip lamp 100 disposed on a screen 10 according to an embodiment of the present invention. Figure 2 FIG. 1 shows a rear view of a clip lamp 100 disposed on a screen 10 according to an embodiment of the present invention.

[0035] The screen 10 has a front surface 10f, a rear surface 10b and an upper surface 10t, wherein the upper surface 10t connects the front surface 10f and the rear surface 10b. The clamp lamp 100 includes a first light source 110 and a clamping body 120. The clamping body 120 includes a second light source 121, a first clamp 122 and a second clamp 123. The first clamp 122 has a first clamping portion 1221 and a lamp connecting portion 1222, wherein the lamp connecting portion 1222 is connected to the first clamping portion 1221. The first light source 110 is connected to the lamp connecting portion 1222, and the first light source 110 can pivot relative to the lamp connecting portion 1222 to adjust its light-emitting angle. The second clamp 123 has a second clamping portion 1231. In one embodiment, the first clamping portion 1221 and the second clamping portion 1231 are movably connected, for example, they can move relative to each other by a hinge or sliding. In one embodiment, the second light source 121 can be optionally disposed on the second clamping portion 1231; Figure 1 The structural length of the middle clamping body 120 , for example, the first clamping portion 1221 is extended to the rear surface 10 b or the second light source 121 is changed to a structure for adjusting the projection direction. The second light source 121 can also be disposed on the first clamping portion 1221 .

[0036] like Figure 1 As shown, when the clamp lamp 100 clamps the screen 10, the first clamping portion 1221 abuts the front surface 10f, and the second clamping portion 1231 abuts the rear surface 10b, allowing the first light source 110 to be positioned above the upper surface 10t and the second light source 121 to be positioned below the upper surface 10t (the Z-axis in the figure represents the reference direction of up and down). The front surface 10f of the screen 10 faces the first zone Z1 to provide a display for the user. When the first light source 110 of the clamp lamp 100 is turned on, it emits light toward the first zone Z1 to illuminate the front of the screen 10. The rear surface 10b of the screen 10 faces the second zone Z2 and is spaced a distance D from a reference object (e.g., a wall R) in the second zone Z2. When the second light source 121 of the clamp body 120 is turned on, it emits light toward the second zone Z2 to illuminate the rear of the screen 10.

[0037] It should be noted that when the screen 10 is used in a dim environment, providing illumination only in the first zone Z1 results in a significant difference in brightness between the front and rear of the screen 10, which can overstimulate the human eye and cause eye fatigue. Compared to providing illumination only in the first zone Z1, the first light source 110 of the clamp lamp 100 emits light in the first zone Z1, while the second light source 121 of the clamp body 120 simultaneously emits light in the second zone Z2. This reduces the brightness difference between the front and rear of the screen 10, alleviating the discomfort of the human eye caused by high-brightness-darkness contrast.

[0038] Furthermore, the first light source 110 is designed to be located above the top surface 10t of the screen 10 to illuminate the primary reading area (i.e., the first zone Z1) and avoid obstructing the display on the screen 10. However, the second light source 121 is used to provide fill light to the area behind the screen 10 (i.e., the second zone Z2) to reduce brightness differences. Therefore, the height of the second light source 121 is designed to be below the top surface 10t of the screen 10. To accommodate higher brightness requirements for reading environments, the luminous intensity of the first light source 110 can be set higher than that of the second light source 121, with the two being proportional.

[0039] like Figure 1 As shown, the second clamp 123 may optionally include a light-transmitting shield 1232. The light-transmitting shield 1232 can be used to shield the second light source 121, allowing the second light source 121 to be disposed within the second clamp 123 and protecting the second light source 121 from damage due to external environmental contact. Furthermore, the light-transmitting shield 1232 is translucent, allowing light emitted by the second light source 121 to pass through, thereby not affecting the illumination behind the screen 10 and providing waterproof and dustproof properties.

[0040] like Figure 2 As shown, the illumination range IR of the second light source 121 can be designed to be larger than the contour range PR of the rear surface 10b of the screen 10, so as to more effectively reduce the brightness difference between the front and rear of the screen 10. On the contrary, if the illumination range IR is too small, most of the light emitted by the second light source 121 will be blocked by the rear surface 10b of the screen, and an effective fill light effect cannot be formed.

[0041] Please refer to Figures 3 and 4 , Figure 3 A rear view of the second clamping member 123 and the second light source 121 of the clamping lamp 100 is shown. Figure 4 A three-dimensional view of the second clamping member 123 and the second light source 121 of the clamp lamp 100 is shown.

[0042] It should be noted that in Figures 3 and 4 Illustration omitted Figure 1 The light-transmitting shield 1232 is provided to clearly indicate the internal configuration of the second clamp 123. Figure 3As shown, the second light source 121 includes a first light array 1211, a second light array 1212, and a third light array 1213. The first light array 1211 and the second light array 1212 are arranged parallel to each other. One end of the third light array 1213 is connected to the first light array 1211, and the other end of the third light array 1213 is connected to the second light array 1212. Specifically, the clamp lamp 100 also includes a counterweight 130 disposed within the second clamp 123. The first light array 1211 and the second light array 1212 are disposed on opposite sides of the counterweight 130, corresponding to the first side surface 130s1 and the first side surface 130s2, respectively. The third light array 1213 is disposed on a side connected between the two sides of the counterweight 130, corresponding to the third side surface 130s3. In other words, the third light array 1213 is disposed between the first light array 1211 and the second light array 1212. The third light array 1213 can be, but is not limited to, arranged perpendicularly to the first light array 1211 and the second light array 1212 to form a U-shaped arrangement. The first light array 1211 is configured to emit light to the right of the front surface 10f facing the screen 10t, the second light array 1212 is configured to emit light to the left of the front surface 10f facing the screen 10t, and the third light array 1213 is configured to emit light above the front surface 10f facing the screen 10t. This provides fill light to the rear periphery of the screen 10.

[0043] like Figure 4 As shown, the light emission direction of the third light array 1213 forms an angle θ with the adjacent third side surface 130s3 of the counterweight 130. Similarly, the first light array 1211 and the second light array 1212 can form an angle θ with the adjacent first side surface 130s1 and second side surface 130s2 of the counterweight 130, respectively. If the angle θ is approximately 90 degrees, the first light array 1211 and the second light array 1212 emit light directly toward the left and right areas of the screen 10, while the third light array 1213 emits light directly toward the upper area of ​​the screen 10. This results in a weaker fill light effect from the second light source 121 behind the screen 10 and directs light to the eyes of users passing by or located to the left and right areas of the screen 10. Therefore, preferably, the angle θ is designed to be an acute angle, so that the first light-emitting array 1211, the second light-emitting array 1212 and the third light-emitting array 1213 can emit light toward the back and sides of the screen 10. Compared with the case where the angle θ is not an acute angle, it can provide better fill light effect behind the screen 10 and avoid direct exposure to human eyes passing through / located in the left and right areas of the screen 10.

[0044] Figure 5A functional block diagram of some components of the clamp lamp 100 according to an embodiment of the present invention is shown. The clamp lamp 100 may further include a light sensor LS, a distance sensor DS, a processing module PM, and a clamp lamp interface LI. The light sensor LS may be disposed outside the clamp lamp 100 to sense the illuminance value of the first area Z1, and the processing module PM is coupled to the light sensor LS and controls the luminous intensity of the second light source 121 according to the sensed illuminance value of the first area Z1, so that the illuminance value of the second area Z2 is lower than the illuminance value of the first area Z2. In one embodiment, the processing module PM may control the luminous intensity of the second light source 121 so that the illuminance value of the second area Z2 is approximately 1 / 3 of the illuminance value of the first area Z1, that is, the illuminance value of the first area Z1 is approximately 3 times the illuminance value of the second area Z2, which is an illuminance difference range that does not easily fatigue the human eye.

[0045] A distance sensor DS can be mounted on the exterior of the clamp lamp 100. When the clamp lamp 100 is clamped to the screen 10, the distance sensor DS senses the distance D between the rear surface 10b of the screen 10 and the wall R. The processing module PM then controls the luminous intensity of the second light source 121 based on this distance D. Specifically, the distance D is positively correlated with the luminous intensity of the second light source 121. As the distance D increases, the brightness of the light reflected from the wall R decreases, so the luminous intensity of the second light source 121 must be increased to maintain the brightness difference between the front and rear of the screen 10. Conversely, as the distance D decreases, the brightness of the light reflected from the wall R increases, so the luminous intensity of the second light source 121 can be reduced. By adjusting the luminous intensity of the second light source 121 based on the distance between the rear surface 10b of the screen 10 and a reference object, a customized lighting environment can be provided.

[0046] The clip lamp 100 can be coupled to a transmission interface of the screen 10 via its clip lamp interface L1 to receive a setting related to the current display image on the screen 10. The clip lamp interface L1 and the transmission interface of the screen 10 can be, for example, Universal Serial Bus (USB) sub-ports. These settings, for example, include parameters such as the brightness, color temperature, sharpness, and contrast of the current display image. The processing module PM can control the brightness and color values ​​of the first light source 110 and the second light source 121 based on these settings, thereby better referencing the display information of the current display image on the screen 10 for lighting adjustment and automatically providing lighting control that adapts to the screen display conditions. In one embodiment, the clip lamp 100 can be adapted to couple to the transmission interface of the screen 10 to obtain the screen brightness value. The processing module PM can then deactivate the first light source. That is, without activating the first light source 110, the processing module PM can adjust the light intensity of the second light source 121 accordingly based on the screen brightness value, thereby enabling the second light source 121 to be controlled independently of the first light source 110. Furthermore, the brightness value of the above-mentioned screen is not limited to being obtained and adjusted only from the transmission interface coupling of the screen 10, but can also be directly obtained through the clamp lamp 100. For example, the internal setting value of the clamp lamp 100 can be obtained and the brightness value can be adjusted through a button switch that is matched with or included in the clamp lamp 100.

[0047] Specifically, refer to Figures 3 and 4 10. The first, second, and third light arrays 1211, 1212, and 1213 in FIG. The set values ​​include first, second, and third set values ​​corresponding to the right, left, and top regions of the live display image on screen 10, respectively. The processing module PM controls the first, second, and third light arrays 1211, 1212, and 1213 to set corresponding brightness and color values ​​based on the first, second, and third set values ​​corresponding to the regions of the live display image. For example, if the brightness of the right region of the live display image on screen 10 is too low / too high, the processing module PM controls the corresponding first light array 1211 to decrease / increase its brightness to reduce the brightness difference between screen 10 and the surrounding environment. Similarly, the brightness of the third light array 1213 / second light array 1212 can be individually controlled to adjust the brightness of the top / left regions of the live display image on screen 10. In this way, each light-emitting array can be controlled to match the area of ​​the display screen corresponding to each light-emitting array, thereby achieving a more precise independent zone light control effect.

[0048] Please refer to Figure 6, which illustrates a flow chart of a light emission control method S of the clamp lamp 100 according to an embodiment. In step S110, the clamp lamp 100 is clamped to the screen 10 so that the first light source 110 is located above the upper surface 10t of the screen 10 and the second light source 121 is located below the upper surface 10t of the screen 10.

[0049] In step S120, the illuminance value of the environment in which the screen 10 is used is sensed. For example, the illuminance value can be sensed by a light sensor LS. The illuminance value of the environment in which the screen 10 is used is a comprehensive sense of the screen light of the screen 10 display and the reflected light of the desktop on which the screen 10 is placed.

[0050] In step S130, the luminous intensity of the first light source 110 is calculated according to the illuminance value of the use environment. For example, the processing module PM can preliminarily calculate the luminous intensity required by the first light source 110 to match the ambient illuminance of general screen use conditions.

[0051] In step S140, the first light source 110 is controlled to emit light toward the first area Z1 facing the front surface 10f of the screen 10. For example, the processing module PM can control the first light source 110 to emit light as the main lighting supply for the first area Z1 where the user faces the screen 10.

[0052] In step S150, it is determined whether the illuminance value of the first zone Z1 meets a predetermined threshold. For example, the determination can be made by the processing module PM, and the predetermined threshold can be defined as approximately 500 lux, which meets the recommended ambient brightness for general screen use.

[0053] In step S161, if a predetermined threshold is met, the second light source 121 is controlled to emit light toward the second zone Z2 facing the rear surface 10b of the screen 10. For example, the processing module PM can control the second light source 121 to emit light to reduce the brightness difference between the front and rear of the screen 10, providing fill light. Specifically, the processing module PM can control the light intensity of the second light source 121 so that the illuminance value in the second zone Z2 is approximately 1 / 3 of the illuminance value in the first zone Z1, which is designed to reduce eye fatigue. For example, if the illuminance value in the first zone Z1 reaches approximately 500 lux, the illuminance value in the second zone Z2 is controlled to approximately 170 lux.

[0054] In step S162, if the predetermined threshold is not met, the luminous intensity of the first light source Z1 is calculated based on the illuminance value of the first zone Z1. For example, the processing module PM can recalculate the required luminous intensity of the first light source 110 to intelligently adjust the luminous intensity to suit the current environment.

[0055] In addition, the processing module PM can be used to make the luminous intensity of the first light source 110 higher than the luminous intensity of the second light source 121 and to form a ratio relationship.

[0056] In addition, the light sensor LS can sense the illumination value of the first area Z1, and the processing module PM controls the light intensity of the second light source 121 according to the illumination value of the first area Z1, so that the illumination value of the second area Z2 is lower than that of the first area Z1.

[0057] In addition, the distance D between the rear surface 10 b of the screen 10 and the wall R1 can be sensed by the distance sensor DS, and the processing module PM controls the light intensity of the second light source 121 according to the distance D.

[0058] In addition, the processing module PM can be used to make the luminous intensity of the first light source 110 higher than the luminous intensity of the second light source 121 and to form a ratio relationship.

[0059] Furthermore, the clip lamp 100 can be coupled to a transmission interface of the screen 10 to obtain the brightness of the screen 10. The processing module PM controls the luminous intensity of the second light source 121 based on this brightness. Through the coupling between the clip lamp 100 and the screen 10, it can receive settings related to the real-time display image on the screen 10. The processing module PM controls the brightness and color of the second light source 121 based on these settings.

[0060] As described in the above embodiments, the first light source and the second light source of the clamp lamp clamped on the screen can emit light simultaneously in the front and rear of the screen respectively, so as to reduce the brightness difference between the front and rear of the screen. Compared with the lighting condition where only a single light is emitted in front of the screen, the clamp lamp of the present invention can make the human eyes less tired when using the screen, thereby achieving the beneficial effect of eye protection.

[0061] The present invention has been described with reference to the above embodiments. However, the above embodiments are merely exemplary embodiments of the present invention. It should be noted that the disclosed embodiments do not limit the scope of the present invention. On the contrary, modifications and improvements that do not depart from the spirit and scope of the present invention are intended to be protected by the present invention.
