Abstract

This invention provides a lamp, including at least a lamp head, a connecting structure, and a first lamp arm. The lamp head and the first lamp arm are connected by a connecting mechanism. When the lamp head and the first lamp arm are disassembled and then reconnected by the connecting mechanism, the angle between the lamp head and the first lamp arm is changed. At the same time, the illumination range emitted by the light source from the first retracted state to the second retracted state covers the user's eyes. In the first retracted state, some light directly shines into the user's eyes, while in the second retracted state, the light does not directly shine into the user's eyes. This improves the problem of the light emitted by the light source directly shining into the eyes and causing glare to the user.

[0036] To provide a further understanding of the purpose, structure, features and functions of the present invention, detailed descriptions are provided below with reference to embodiments.

[0037] Please refer to Figures 1-6 As shown, Figure 1 This is a perspective view of a lamp 100 in its unfolded state P1 according to an embodiment of the present invention. Figure 2 This is a schematic diagram of a lamp 100 in its unfolded state P1 disposed on an object 101 according to an embodiment of the present invention. Figure 3 This is a perspective view of a lamp 100 in a first retracted state P2 according to an embodiment of the present invention. Figure 4 This is a schematic diagram of a lamp 100 in a first retracted state P2 disposed on an object 101 according to an embodiment of the present invention. Figure 5 This is a perspective view of a lamp 100 in its second retracted state P3 according to an embodiment of the present invention. Figure 6 This is a schematic diagram of a lamp 100 in the second retracted state P3 disposed on an object 101 according to an embodiment of the present invention.

[0038] This invention provides a lamp 100, which can be disposed on an object 101. The object 101 can be the back of the display surface of a laptop computer when it is unfolded, or the back of a desktop computer monitor, depending on the actual application scenario. The lamp 100 includes a lamp head 11, a connecting structure 12, a first lamp arm 13, and a second lamp arm 14. The lamp head 11 has a light source 111 that emits light. The connecting structure 12 connects the lamp head 11 to one end of the first lamp arm 13. The second lamp arm 14 is pivotally connected to the other end of the first lamp arm 13. When the lamp 100 is in the unfolded state P1 and the second lamp arm 14 is disposed on the object 101, the light source 111 emits a first light ray 1111 and a second light ray 1112. The first light ray 1111 and the second light ray 1112 are the boundary light rays of the illumination range of the light source 111 when it is in the unfolded state P1 (see...). Figure 2 (As shown); When the lamp 100 is in the first retracted state P2 and is placed on the object 101, the light source 111 emits a third ray 1113 and a fourth ray 1114. The third ray 1113 and the fourth ray 1114 are the boundary rays of the illumination range of the light source 111 in the first retracted state P2 (see...). Figure 4 (As shown); When the lamp head 11 rotates relative to the first lamp arm 13 around the axis, the lamp head 11 connects with the first lamp arm 13 through the connecting structure 12, so that the lamp 100 is in the second retracted state P3 and is placed on the object 101, the light source 111 emits the fifth ray 1115 and the sixth ray 1116. The fifth ray 1115 and the sixth ray 1116 are the boundary rays of the illumination range of the light source 111 when in the second retracted state P3 (see...). Figure 6 As shown), the user's eyes 103 are directly illuminated by the third light ray 1113 and the fourth light ray 1114, i.e., the direct illumination range formed by the third light ray 1113 and the fourth light ray 1114 covers the user's eyes 103. The user's eyes 103 are not directly illuminated by the first light ray 1111 and the second light ray 1112, i.e., the direct illumination range formed by the first light ray 1111 and the second light ray 1112 does not cover the user's eyes 103. The user's eyes 103 are not directly illuminated by the fifth light ray 1115 and the sixth light ray 1116, i.e., the direct illumination range formed by the fifth light ray 1115 and the sixth light ray 1116 does not cover the user's eyes 103. In this way, the light fixture 100 installed on the object 101 in the unfolded state P1 and the light fixture 100 in the retracted state after being rotated by the connecting structure 12 can avoid the problem of the light source directly shining on the consumer's eyes 103 and causing glare.

[0039] Reference Figure 1 and Figure 2 As shown, when the lamp 100 is in the unfolded state P1, the second lamp arm 14 is positioned on the object 101, and the first lamp arm 13 and the second lamp arm 14 form a first angle C1; (Refer to...) Figure 3 andFigure 4 As shown, when the lamp 100 is in the first retracted state P2, the second lamp arm 14 is positioned on the object 101, and the first lamp arm 13 and the second lamp arm 14 form a second angle C2, which is smaller than the first angle C1; (Refer to...) Figure 5 and Figure 6As shown, when the lamp 100 is in the second retracted state P3, the second lamp arm 14 is positioned on the object 101, and the first lamp arm 13 and the second lamp arm 14 form a third angle C3, which is less than the first angle C1 and equal to the second angle C2. In a specific implementation, when the lamp 100 is in the fully extended state P1, the first lamp arm 13 and the second lamp arm 14 form a large angle, namely the first angle C1, and the free end of the second lamp arm 14 is positioned on the object 101. The light source 111 of the lamp head 11 is used for illumination, emitting a first light ray 1111. The first light ray 1111 is the light emitted by the light source 111 in the extended state P1 that is close to the user's eye, and the first light ray 1111 does not pass through the user's eye for illumination. When the lamp 100 is in the first retracted state P2, the first lamp arm 13 and the second lamp arm 14 form the minimum angle, i.e., the second angle C2. The second lamp arm 14 is set on the object 101. The light source 111 of the lamp head 11 is used to illuminate and emit a third light 1113. The third light 1113 is the light emitted by the light source 111 when it is in the first retracted state P2 and is close to the user. Because the second lamp arm 14 is retracted, when the lamp 100 is in the first retracted state P2 and is set on the object 101, the third light 1113 will pass through the human eye. To prevent the third ray 1113 from passing through the user's eyes 103, the lamp head 11 is rotated 180° relative to the first lamp arm 13, and then connected to the first lamp arm 13 again via the connecting structure 12, forming a second retracted state P3. This means either the lamp head 11 remains stationary while the first lamp arm 13 rotates 180° and is then connected via the connecting structure 12, or the first lamp arm 13 remains stationary while the lamp head 11 rotates 180° and is then connected via the connecting structure 12. At this point, the first lamp arm 13 and the second lamp... Arm 14 remains at the minimum included angle, i.e., the third angle C3. The second lamp arm 14 is set on object 101. The light source 111 of the lamp head 11, which is in the second retracted state P3, emits the fifth light ray 1115. The fifth light ray 1115 is the critical point at which the light emitted by the light source 111 approaches the user when it is in the second retracted state P3. The relative rotation of the lamp head 11 and the first lamp arm 13 causes the fifth light ray 1115 to deflect downwards and not pass through the human eye, thus achieving the effect of avoiding direct light shining into the human eye and causing the user to feel glare. It is worth mentioning that in the unfolded state P1, the illumination range formed by the first ray 1111 and the second ray 1112 is defined as directly illuminating the user's eyes 103, and its light intensity is relatively strong; while the first ray 1111 and the second ray 1112 entering the user's eyes 103 after reflection or diffuse reflection is defined as indirect illumination, and its light intensity is weaker and weaker than the light intensity of direct illumination; the third ray 1113 and the fourth ray 1114 in the first closed state P2 and the fifth ray 1115 and the sixth ray 1116 in the second closed state P3 are similar and will not be described again.

[0040] Next, the specific structure and positional relationship of the lamp head 11, the connecting structure 12, the first lamp arm 13 and the second lamp arm 14 will be described in detail.

[0041] Please refer to Figures 1-6 As shown, the lamp head 11 has a first end 112 and a second end 113. The first end 112 is equipped with a light source 111, which can be strip-shaped to ensure even illumination of the laptop keyboard area or work area. The second end 113 is connected to the first lamp arm 13 via a connecting structure 12. The light source 111 can be fixedly mounted on the first end 112 to prevent changes in the illumination angle range of the light source 111 during use, thus maintaining a better illumination angle for the laptop keyboard area or work area. Figure 2 and Figure 6 As shown, the light source 111 illuminates at a better angle and avoids direct light shining into the user's eyes 103, thus preventing the user from feeling glare when using it.

[0042] Refer to together Figures 7-12 As shown, Figure 7 This is a schematic diagram of a lamp 100 according to an embodiment of the present invention, from an unfolded state P1 to a first retracted state P2. Figure 8 This is a schematic diagram of a lamp 100 according to an embodiment of the present invention, from a first retracted state P2 to a second retracted state P3. Figure 9 This is an exploded view of a lamp 100 in its first retracted state P2 according to an embodiment of the present invention. Figure 10 This is a cross-sectional view of the lamp 100 in the first retracted state P2 according to an embodiment of the present invention along A-A'. Figure 11 This is an exploded view of a lamp 100 in the second retracted state P3 according to an embodiment of the present invention. Figure 12 This is a cross-sectional schematic diagram along B-B' of a lamp 100 in the second retracted state P3 according to an embodiment of the present invention.

[0043] The first lamp arm 13 has a third end 131 and a fourth end 132. The third end 131 of the first lamp arm 13 is connected to the second end 113 of the lamp head 11 by a connecting mechanism 12, and the fourth end 132 of the first lamp arm 13 is pivotally connected to the second lamp arm 14. When the lamp 100 is in the unfolded state P1, the second lamp arm 12 is positioned on the object 101. At this time, the first lamp arm 13 and the lamp head 11 form a first angle D1, participating in... Figure 2 As shown; when the lamp 100 is in the first retracted state P1, the second lamp arm 14 is positioned on the object 101. At this time, the first lamp arm 13 and the lamp head 11 form a second angle D2, which is equal to the first angle D2. Figure 4 As shown; when the lamp 100 is in the second retracted state P3, the second lamp arm 14 is positioned on the object 101, and the first lamp arm 13 forms a third angle D3 with the lamp head 11, which is smaller than the second angle D2. For specific implementation, refer to... Figure 7As shown, from the unfolded state P1 to the first retracted state P2, the angle between the first lamp arm 13 and the lamp head 11 remains constant from the first angle D1 to the second angle D2. The angle between the first lamp arm 13 and the second lamp arm 14 gradually decreases, from the first angle C1 to the second angle C2. In a preferred embodiment, the second angle C2 is 0°. (Refer to...) Figure 8 As shown, from the first retracted state P1 to the second retracted state P2, the angle between the first lamp arm 13 and the lamp head 11 decreases from the second angle D2 to the third angle D3. The angle between the first lamp arm 13 and the second lamp arm 14 remains unchanged at 0°. The user separates the lamp head 11 from the first lamp arm 13, and then the lamp head 11 is rotated 180° or the first lamp arm 13 is rotated 180° and then connected to the first lamp arm 13 by the connecting mechanism 12, so that the angle between the lamp head 11 and the first lamp arm 13 becomes smaller. The lamp head 11 and the first lamp arm 13 are not pivotally connected, while the first lamp arm 13 and the second lamp arm 14 are pivotally connected. When adjusting the opening angle of the laptop, only the angle of the first lamp arm 13 and the second lamp arm 14 needs to be adjusted to keep the lamp head 11 parallel and ensure that the light source 111 illuminates the display area more effectively. When the light source 111 needs to illuminate the laptop display at close range, the lamp head 11 and the first lamp arm 13 can be disassembled and rotated for reassembly. The light source 111 will then illuminate the display surface without directly shining into the eyes.

[0044] The second lamp arm 14 has a fifth end 141, a sixth end 142, a first sidewall 143, and a second sidewall 144. The fifth end 141 is opposite to the sixth end 142 and is pivotally connected to the fourth end 132 of the first lamp arm 13. The sixth end 142 is the free end of the second lamp arm 14. The first sidewall 143 and the second sidewall 144 are two sidewalls of the second lamp arm 144 that are opposite each other in the length direction. When the lamp 100 is in the unfolded state P1, the first sidewall 143 is disposed on the object 101; when the lamp 100 is in the first retracted state P2, the second sidewall 144 is disposed on the object 101; when the lamp 100 is in the second retracted state P3, the first sidewall 143 is disposed on the object 101. Specifically, in the unfolded state P1, the first sidewall 143 of the second lamp arm 14 is located on the back of the laptop display surface, and in the second retracted state P3, the first sidewall 143 of the second lamp arm 14 is located on the back of the laptop display surface. The light emitted by the light source 11 in both the unfolded state P1 and the second retracted state P3 does not directly shine into the human eye. At the same time, the same sidewall 143 of the second lamp arm 14 is attached to the object 101.

[0045] The connecting mechanism 12 has a first mating part 121 and a second mating part 122. The first mating part 121 is disposed on the lamp head 11, and the second mating part 122 is disposed on one end of the first lamp arm 13. The first lamp arm 13 is engaged with the lamp head 11 by the first mating part 121 and the second mating part 122 to form a second included angle D2. After rotating the first lamp arm 13, the first lamp arm 13 is engaged with the lamp head 11 by the first mating part 121 and the second mating part 122 to form a third included angle D3. The second included angle D2 and the third included angle D3 are not equal. In other words, from the first retracted state P2 to the second retracted state P3, the first mating part 121 on the lamp head 11 separates from the second mating part 122 on the first lamp arm 13. Rotating the first lamp arm 13 or rotating the lamp head 14 re-engages the first mating part 121 on the lamp head 11 with the second mating part 122 on the first lamp arm 13, causing the angle between the lamp head 11 and the first lamp arm 13 to decrease from the second angle D2 to the third angle D3. Specifically, the engagement direction of the first mating part 121 and the second mating part 122 is the first direction E1, and the length direction of the first lamp arm 13 is the second direction E2, with the first direction E1 deviating from the second direction E2. In a better embodiment, the first mating part 121 is either a concave structure or a convex structure, and the second mating part 122 is either a concave structure or a convex structure. Specifically, when the first mating part 121 is a convex structure and the second mating part 122 is a concave structure, the protruding direction of the convex structure is the first direction E1. The first direction E1 is not parallel to the second direction E2 where the length direction of the first lamp arm E2 is located. This causes the angle between the first lamp arm 13 and the lamp head 11 to change from the first closed state P2 to the second closed state P3 when the first mating part 121 and the second mating part 122 are engaged. When the first mating part 121 is a concave structure and the second mating part 122 is a convex structure, the principle can be deduced as described above, and will not be repeated here.

[0046] The lamp 100 also includes an adsorption structure 15, which is disposed on the object 101. When the second lamp arm 14 is disposed on the object 101, the other end of the second lamp arm 14 is adsorbed onto the adsorption structure 15 of the object 101. In a preferred embodiment, the second lamp arm 14 may be disposed on the side wall of the object 101 or on the end face of the object 101, depending on the shape of the second lamp arm 14, and is not limited thereto. In a preferred embodiment, the adsorption structure 15 is a magnetic patch disposed on the back of the laptop display surface, and the second lamp arm 14 is also magnetic, magnetically adsorbed onto the magnetic patch on the back of the laptop display surface.

[0047] In this embodiment of the invention, the first lamp arm 13 has a first through groove 130 that extends through the first lamp arm 13. When the lamp 100 is in a first retracted state P2 or a second retracted state P3, the second lamp arm 14 is embedded in the first through groove 130. Specifically, when the lamp 100 is in the first retracted state P2 or the second retracted state P3, the second lamp arm 14 is completely embedded in the first through groove 130 of the first lamp arm 13. The first sidewall 143 and the second sidewall 144 of the second lamp arm 14 are flush with the wall surface of the first lamp arm 13, or the first sidewall 143 and the second sidewall 144 of the second lamp arm 14 are slightly protruding from the wall surface of the first lamp arm 13. In this way, the second lamp arm 14 can be better magnetically attracted to the adsorption structure 15 on the back of the laptop display.

[0048] In this embodiment of the invention, object 101 is placed on bearing plane 102 at an angle to bearing plane 102. Second lamp arm 14 is disposed on object 101. When lamp 100 is in the unfolded state P1, the distance between light source 111 and bearing plane 102 is a first height H1. When lamp 100 is in the first retracted state P1, the distance between light source 111 and bearing plane 102 is a second height H2. When lamp 100 is in the second retracted state P2, the distance between light source 111 and bearing plane 102 is a third height H3. The first height H1 is greater than the second height H2, and the second height H2 is greater than the third height H3. In practice, the lamp 100 in the unfolded state P1 is positioned on the back of the laptop display for illuminating the keyboard or work area, with the lamp head 11 being relatively far from the supporting plane 102. When the user wants the light source 111 to emit light onto the laptop display, the second lamp arm 14 is rotated and retracted to the first lamp arm 13, causing the lamp 100 to be adjusted from the unfolded state P1 to the first retracted state P2. In this state, the lamp head 11 is closer to the supporting plane 102, and while the light source 111 emits light onto the display, the light still directly shines into the eyes 103, causing glare. At this point, the user adjusts the lamp 100 from the first retracted state P2 to the second retracted state P3, reducing the lamp head 11's tilt angle and bringing the light source 111 closer to the supporting plane 102. This reduces the lamp head 11's tilt angle, thus solving the problem of excessive glare caused by the lamp head 11's tilt angle when the lamp 100 is in the first retracted state P2.

[0049] In this embodiment of the invention, from the unfolded state P1 to the first retracted state P2, the second lamp arm 14 rotates around the fourth end 132 of the first lamp arm 13 until the second lamp arm 14 is embedded in the first through slot 130 of the first lamp arm 13. The angle between the second lamp arm 14 and the first lamp arm 13 gradually decreases from the first angle C1 to the second angle C2, where the second angle C2 is close to 0°. The angle between the first lamp arm 13 and the lamp head 11 remains unchanged from the first angle D1 to the second angle D2. The lamp 100 is disposed on the object 101, and the boundary light emitted by the light source 111 changes from the first light ray 1111 to the third light ray 1113. The distance between the light source 111 and the bearing plane 102 decreases from the first distance H1 to the second distance H2. From the first retracted state P2 to the second retracted state P3, the second lamp arm 14 remains in contact with the first lamp arm 13, and the angle between the second lamp arm 14 and the first lamp arm 13 remains constant at approximately 0° from the second angle C2 to the third angle C3. First, the lamp head 11 separates from the first lamp arm 13. The first lamp arm 13 rotates 180° along its length and then connects to the lamp head 11 via the connecting mechanism 12. The angle between the lamp head 11 and the first lamp arm 13 decreases from the second angle D2 to the third angle D3. The lamp 100 is placed on the object 101, and the boundary light emitted by the light source 111 changes from the third ray 1113 to the fifth ray 1115. The distance between the light source 111 and the supporting plane 102 decreases from the second distance H2 to the third distance H3. Thus, the lamp 100 can be unfolded and retracted, and the lamp head 11 and the first lamp arm 13 are detachable, making the lamp 100 more versatile.

[0050] It is worth mentioning that the present invention can adopt not only a double-lamp arm structure, but also a single-lamp arm structure, that is, the first lamp arm 13 and the second lamp arm 14 can be folded into a single structure, while the other components are retained. The present invention provides a lamp 100, which is disposed on an object 101. The lamp 100 includes a lamp head 11, a connecting structure 12 and a first lamp arm 13. The lamp head 11 has a light source 111, which emits light. The connecting structure 12 connects the lamp head 11 to one end of the first lamp arm 13. When the lamp 100 is in the first folded state P2 and is disposed on the object 101, the light source 111 emits a third light ray 1113 and a fourth light ray 1114. The third light ray 1113 and the fourth light ray 1114 are the boundary light rays of the illumination range of the light source 111 when in the first folded state P2 (see Figure 4 (As shown); When the lamp head 11 rotates relative to the first lamp arm 13 as an axis, the lamp head 11 connects with the first lamp arm 13 through the connecting structure 12, so that the lamp 100 is in the second retracted state P3 and is placed on the object 101, the light source 111 emits the fifth ray 1115 and the sixth ray 1116. The fifth ray 1115 and the sixth ray 1116 are the boundary rays of the illumination range of the light source 111 when in the second retracted state P3 (see...). Figure 6As shown, the user's eyes 103 are within the direct illumination range of the third light 1113 and the fourth light 1114, and outside the direct illumination range of the fifth light 1115 and the sixth light 1116. In this way, the lamp 100, which is in a retracted state after the connecting structure 12 is rotated, can avoid the problem of the light source directly shining on the consumer's eyes 103 and causing glare.

[0051] In this embodiment of the invention, when the lamp 100 is in the first retracted state P1, the first lamp arm 13 is disposed on the object 101, and at this time, the first lamp arm 13 and the lamp head 11 form a second angle D2; when the lamp 100 is in the second retracted state P3, the first lamp arm 13 is disposed on the object 101, and the first lamp arm 13 and the lamp head 11 form a third angle D3, the third angle D3 being smaller than the second angle D2. For specific implementation, refer to... Figure 8 As shown, from the first retracted state P1 to the second retracted state P2, the angle between the first lamp arm 13 and the lamp head 11 decreases from the second angle D2 to the third angle D3. The user can detach the lamp head 11 from the first lamp arm 13, and then rotate the lamp head 11 180° or the first lamp arm 13 180° before connecting them via the connecting mechanism 12, thus reducing the angle between the lamp head 11 and the first lamp arm 13. The lamp head 11 and the first lamp arm 13 are not pivotally connected. During use, the lamp head 11 and the first lamp arm 13 can be disassembled and rotated for reassembly. The light source 111 illuminates the display surface without directly shining into the user's eyes.

[0052] The first lamp arm 13 has opposing third sidewalls 133 and fourth sidewalls 134, which are two opposing sidewalls along the length of the first lamp arm 13. When the lamp 100 is in the first retracted state P2, the third sidewall 133 is located on the object 101; when the lamp 100 is in the second retracted state P3, the fourth sidewall 134 is located on the object 101. Specifically, in the first retracted state P2, the third sidewall 133 of the first lamp arm 13 is located on the back of the laptop display surface, and in the second retracted state P3, the fourth sidewall 134 of the first lamp arm 13 is located on the back of the laptop display surface. The light emitted by the light source 11 in the first retracted state P2 directly illuminates the human eye, while the light emitted by the light source 11 in the second retracted state P3 does not directly illuminate the human eye.

[0053] The connecting mechanism 12 has a first mating part 121 and a second mating part 122. The first mating part 121 is disposed on the lamp head 11, and the second mating part 122 is disposed on one end of the first lamp arm 13. The first lamp arm 13 is engaged with the lamp head 11 by the first mating part 121 and the second mating part 122 to form a second included angle D2. After rotating the first lamp arm 13, the first lamp arm 13 is engaged with the lamp head 11 by the first mating part 121 and the second mating part 122 to form a third included angle D3. The second included angle D2 and the third included angle D3 are not equal. In other words, from the first retracted state P2 to the second retracted state P3, the first mating part 121 on the lamp head 11 separates from the second mating part 122 on the first lamp arm 13. Rotating the first lamp arm 13 or rotating the lamp head 14 re-engages the first mating part 121 on the lamp head 11 with the second mating part 122 on the first lamp arm 13, causing the angle between the lamp head 11 and the first lamp arm 13 to decrease from the second angle D2 to the third angle D3. Specifically, the engagement direction of the first mating part 121 and the second mating part 122 is the first direction E1, and the length direction of the first lamp arm 13 is the second direction E2, with the first direction E1 deviating from the second direction E2. In a better embodiment, the first mating part 121 is either a concave structure or a convex structure, and the second mating part 122 is either a concave structure or a convex structure. Specifically, when the first mating part 121 is a convex structure and the second mating part 122 is a concave structure, the protruding direction of the convex structure is the first direction E1. The first direction E1 is not parallel to the second direction E2 where the length direction of the first lamp arm E2 is located. This causes the angle between the first lamp arm 13 and the lamp head 11 to change from the first closed state P2 to the second closed state P3 when the first mating part 121 and the second mating part 122 are engaged. When the first mating part 121 is a concave structure and the second mating part 122 is a convex structure, the principle can be deduced as described above, and will not be repeated here.

[0054] The lamp 100 also includes an adsorption structure 15, which is disposed on the object 101. When the first lamp arm 13 is disposed on the object 101, the other end of the first lamp arm 13 is adsorbed onto the adsorption structure 15 of the object 101. In a preferred embodiment, the first lamp arm 13 may be disposed on the side wall of the object 101 or on the end face of the object 101, depending on the shape of the first lamp arm 13, and is not limited thereto. In a preferred embodiment, the adsorption structure 15 is a magnetic patch disposed on the back of the laptop display surface, and the first lamp arm 13 is also magnetic, magnetically adsorbed onto the magnetic patch on the back of the laptop display surface.

[0055] In this embodiment of the invention, object 101 is placed on bearing plane 102 at an angle to bearing plane 102. First lamp arm 13 is disposed on object 101. When lamp 100 is in the first retracted state P1, the distance between light source 111 and bearing plane 102 is a second height H2. When lamp 100 is in the second retracted state P2, the distance between light source 111 and bearing plane 102 is a third height H3. The first height H1 is greater than the second height H2, and the second height H2 is greater than the third height H3. In practice, when the lamp head 11 is in the first retracted state P2, it is closer to the supporting plane 102. The light source 111 emits light that shines on the display surface, but the light will also shine directly into the eyes 103, causing a glaring sensation. At this time, the user adjusts the lamp 100 from the first retracted state P2 to the second retracted state P3. The lamp head 11 lift angle is reduced, and the light source 111 is closer to the supporting plane 102. This reduces the lamp head 11 lift angle to solve the problem of glare caused by the lamp head 11 lift angle being too large when the lamp 100 is in the first retracted state P2.

[0056] In this embodiment of the invention, from the first retracted state P2 to the second retracted state P3, the lamp head 11 first separates from the first lamp arm 13. The first lamp arm 13 rotates 180° along its own length direction and then connects to the lamp head 11 via the connecting mechanism 12. The angle between the lamp head 11 and the first lamp arm 13 decreases from the second angle D2 to the third angle D3. The lamp 100 is placed on the object 101, and the boundary light emitted by the light source 111 changes from the second light ray 1112 to the third light ray 1113. The distance between the light source 111 and the supporting plane 102 decreases from the second distance H2 to the third distance H3. Thus, the lamp 100 can be unfolded and retracted, and the lamp head 11 and the first lamp arm 13 are detachable, making the lamp 100 more versatile.

[0057] In summary, the lamp provided by this invention includes a lamp head, a connecting structure, a first lamp arm, and a second lamp arm. The lamp head has a light source that emits light. The connecting structure connects the lamp head to one end of the first lamp arm. The second lamp arm is pivotally connected to the other end of the first lamp arm. When the lamp is in an extended state and the second lamp arm is placed on an object, the light source emits a first light and a second light, which are the boundary lights of the illumination range of the light source in the extended state. When the lamp is in a first retracted state and placed on an object, the light source emits a third light and a fourth light, which are the boundary lights of the illumination range of the light source in the first retracted state. When the lamp head rotates relative to the first lamp arm as an axis... The rear lamp head is connected to the first lamp arm via a connecting structure. When the lamp is in the second retracted state and placed on an object, the light source emits a fifth and a sixth ray. The fifth and sixth rays are the boundary rays of the light source's illumination range in the second retracted state. The illumination range formed by the third and fourth rays covers the user's eyes, while the illumination range formed by the first and second rays does not cover the user's eyes. Thus, the lamp, whether in the unfolded state or in the retracted state after the connecting structure is rotated, avoids the light source directly shining into the consumer's eyes, preventing glare.
