The light source technology has been significantly innovated. LED light sources have occupied a dominant position in the field of cabinet body lighting due to their advantages such as energy saving, environmental protection, long service life, small size, high luminous efficiency, and good color rendering. For example, MiniLED backlight technology greatly reduces the thickness of lamps and lanterns, which not only improves the aesthetic appearance, but also continuously improves the penetration rate in high-end products. Intelligent control technology has become a new trend. Voice control and human body sensing functions make the use of cabinet lighting more convenient. Human body sensing technology can automatically turn on the lamp when the cabinet door or drawer is opened, and automatically turn off the lamp when the cabinet door or drawer is closed. It is not only convenient, but also achieves energy saving. Installation design technology pays more attention to convenience and aesthetics. For example, the embedded cabinet light and the external lamp body. The embedded cabinet light can be directly spliced and installed with the cabinet after slotting through special design, without the need for secondary processing, which not only saves the space inside the cabinet, but also improves the space utilization efficiency and overall aesthetics.

[0020] Compared with the prior art, the drawer lamp for expanding the irradiation angle provided by the present application at least achieves the following beneficial effects:

[0021] Firstly, the drawer lamp for expanding the irradiation angle provided by the present application can realize large-range and dead-angle-free lighting while saving energy and cost. Firstly, the present application provides a herringbone-shaped lampshade, and a V-shaped structure is formed between part of the second side plate and the first side plate. The opening of the V-shaped structure is away from the straight side plate, so that the irradiation of the lamp strip in the lamp shell can be refracted and reflected once. The once-refracted and once-reflected light can increase the lighting range. When the drawer lamp for expanding the irradiation angle is applied to a cabinet body, the light is refracted into the deep dead angle of the cabinet body. Further, part of the second side plate has a corrugated surface, so that the light refracted by the first side plate is reflected by the corrugated surface of the second side plate again. The reflected light can further enhance the lighting range of the lamp strip.

[0022] Secondly, the drawer lamp for expanding the irradiation angle provided by the present application can realize large-range and dead-angle-free lighting while not causing direct damage to the eyes of the user. Firstly, when the drawer lamp for expanding the irradiation angle is installed above the drawer opening, the light irradiated by the lamp strip does not directly shine on the eyes of the user. Further, the corrugated surface of the second side plate further scatters the light in the second-refracted process, which can effectively reduce the light irradiation intensity near the cabinet door, thereby enhancing the softness of the light.

[0023] Thirdly, the drawer lamp for expanding the irradiation angle provided by the present application has a light and thin body and is easy to install. Firstly, the present application can effectively reduce the actual use length of the lamp strip and the required high-power lamp beads required by the corresponding lighting requirements by optimizing the structure of the herringbone-shaped lampshade. The overall weight of the drawer lamp for expanding the irradiation angle can be effectively reduced, so that it is lighter and thinner. Further, part of the second side plate in the lampshade has a corrugated surface structure, which can perform secondary scattering and reflection on the light, thereby increasing the lighting range. In turn, the mechanism can be simplified to reduce the volume.

[0024] Of course, any product implementing the present application does not necessarily need to achieve all the technical effects described above.

The median line of the V-shaped structure intersects the median line of the straight side plate 113, and the slot of the V-shaped structure is away from one side of the straight side plate 113, and is in the same imaginary plane as the inclined side plate 114.

[0072] Continuing to refer to Figures 2-4 As shown, the side of the second side plate 123 away from the inclined side plate 114 is in contact with the side of the straight side plate 113 close to the inclined side plate 114, and the other end of the second side plate 123 is clamped with the inclined side plate 114. The lower side plate 112, the first side plate 122 and part of the straight side plate 113 enclose the lamp strip cavity 13. The lamp strip cavity 13 is a second trapezoidal groove body extending along the length direction X of the lamp housing 1, and the cross-sectional shape of the lamp strip cavity 13 along the width direction Y of the straight side plate 113 is trapezoidal. The lower base of the second trapezoidal groove body is larger than the upper base thereof. The lower base of the second trapezoidal groove body is the first side plate 122, and the trapezoidal side of the second trapezoidal groove body away from the lower side plate 112 is in the same imaginary plane as the side of the second side plate 123 close to the slot of the V-shaped structure. The lamp strip 2 is bonded in the lamp strip cavity 13 along the length direction of the lamp housing 1. The model of the lamp strip 2 can be COB-08. The irradiation direction of the lamp strip 2 is that the upper base of the second trapezoidal groove body points to the lower base thereof. The side of the first side plate 122 close to the slot of the V-shaped structure is a corrugated surface. When the drawer lamp for expanding the irradiation angle is applied to the cabinet 01, the light of the lamp strip 2 penetrates the lower base of the second trapezoidal groove body, i.e. the first side plate 122, and directly irradiates away from the inner corner. The first side plate 122 simultaneously scatters the light. Part of the scattered light passes through the corrugated surface of the second side plate 123, is refracted again to the area deep in the cabinet 01, and through the corrugated surface of the first side plate 122 and the second side plate 123 of the V-shaped structure, the full-area irradiation of the drawer close to or away from the cabinet door area can be achieved, and the irradiation area is increased.

[0073] Specifically, the lower side plate 112 is provided with a first H-shaped groove recessed away from the upper side plate 111 at one side close to the upper side plate 111 and away from the straight side plate 113; the first H-shaped groove is a rectangular groove, and the opening direction of the first H-shaped groove is parallel to the width direction Y of the straight side plate 113. The first side plate 122 is integrally provided with a first I-shaped strip matched with the first H-shaped groove at one end of the outer wall close to the notch of the V-shaped structure; the first I-shaped strip is a rectangular body, and the width of the first I-shaped strip along the width direction Z of the lower side plate 112 is smaller than the width of the first H-shaped groove along the width direction Z of the lower side plate 112. The length directions of the first H-shaped groove and the first I-shaped strip are both along the length direction X of the lamp shell 1; the first H-shaped groove and the first I-shaped strip are used to make the connecting angle corresponding to the notch of the V-shaped structure of the lamp shade 12 and the first side plate 122 be able to be slidably inserted with the lower side plate 112.

The second side plate 123 is provided with a second H-shaped groove matched with the second I-shaped strip at one side close to the straight side plate 113, and the second H-shaped groove is recessed away from the lower side plate 112. The width of the second I-shaped strip along the width direction Y of the straight side plate 113 is equal to the depth of the second H-shaped groove along the width direction Y of the straight side plate 113. The length directions of the second I-shaped strip and the second H-shaped groove are both along the length direction X of the lamp shell 1, and the second I-shaped strip and the second H-shaped groove are used to make the connecting angle corresponding to the notch of the V-shaped structure of the lamp shade 12 and the second side plate 123 be able to be slidably inserted with the upper side plate 111.

[0076] Through the mutual matching and clamping between the first H-shaped groove and the first I-shaped strip, the L-shaped groove and part of the second side plate 123, and the second H-shaped groove and the second I-shaped strip, the lamp shell 11 and the lamp shade 12 can be slidably inserted, so that the lamp shell 11 and the lamp shade 12 can be directly implemented. Further, the mutual matching and clamping between the first H-shaped groove and the first I-shaped strip, the L-shaped groove and part of the second side plate 123, and the second H-shaped groove and the second I-shaped strip can form a triangular structure of the lamp shell 11 and the lamp shade 12, so that the connection of the lamp shell 11 and the lamp shade 12 is more stable.

[0077] Continuing to refer to Figure 2 and Figure 4As shown, the upper side plate 111, the inclined side plate 114, the second side plate 123 and the partial straight side plate 113 enclose the control cavity 14. The control cavity 14 is a third trapezoidal groove body extending along the length direction X of the lamp shell 1.

[0078] With reference to Figure 2 , Figure 4 , Figure 7 and Figure 8 shown, the control assembly 3 includes the control plate 31 and the switch protection cover 32. The switch protection cover 32 is in contact with the control plate 31. The control plate 31 is used to control the switch of the lamp strip 2. The length of the control plate 31 is along the length direction X of the lamp shell 1. The control plate 31 is further clamped in the control cavity 14 along the length direction. The median line of the control plate 31 is parallel to the median line of the upper side plate 111.

[0079] The switch protection cover 32 is used to protect the inductive switch on the control plate 31. Specifically, the geometric center of the upper side plate 111 is provided with an inductive through hole 1111 penetrating the upper side plate 111 along the width direction Y of the straight side plate 113. The shape of the inductive through hole 1111 is rectangular. The median line of the inductive through hole 1111 is parallel to the median line of the upper side plate 111. The width of the inductive through hole 1111 along the width direction Z of the lower side plate 112 is not greater than the width of the upper side plate 111 along the width direction Z of the lower side plate 112. The inductive through hole 1111 is used to penetrate the control cavity 14 and the outside of the lamp shell 11. The switch protection cover 32 is clamped and fixed in the rectangular inductive through hole 1111. The side of the switch protection cover 32 close to the control cavity 14 is inserted with the control plate 31 in the control cavity 14, and the switch protection cover 32 is placed in the inductive through hole 1111. The switch protection cover 32 is inserted with the control plate 31 through the inductive through hole 1111, so as to fix the control plate 31 along the length direction X of the lamp shell 1.

[0080] With reference to Figures 2-4 and Figures 9-12 shown, the fixing assembly 4 includes a trapezoidal left fixing member 41 and a trapezoidal right fixing member 42. The left fixing member 41 includes a left clamping member 411 screwed on the inner wall of one side of the cabinet body 01, and a left plug 412 used to connect the left clamping member 411 and the lamp shell 1 close to the left clamping member 411. The right fixing member 42 includes a right clamping member 421 screwed on the inner wall of one side of the cabinet body 01, and a right plug 422 used to connect the right clamping member 421 and the other end of the lamp shell 1.

[0081] The left clamping piece 411 and the right clamping piece 421 are of the same size, and the structures of the left clamping piece 411 and the right clamping piece 421 are mirror-symmetrical along the middle vertical plane of the straight side plate 113 in the length direction X of the lamp shell 1. The left clamping piece 411 and the right clamping piece 421 are both L-shaped pieces. The left clamping piece 411 is fixed on the left side of the cabinet body 01 along the opening and closing direction of the cabinet door through a screw, and the other side of the left clamping piece 411 away from the cabinet body 01 is inserted and clamped with the left plug 412. The right clamping piece 421 is fixed on one side of the cabinet body 01 along the opening and closing direction of the cabinet door through a screw, and the other side of the right clamping piece 421 away from the cabinet body 01 is inserted and clamped with the right plug 422.

[0082] The left plug 412 and the right plug 422 are of the same size, and the structures of the left plug 412 and the right plug 422 are mirror-symmetrical along the middle vertical plane of the straight side plate 113 in the length direction X of the lamp shell 1. The left plug 412 and the right plug 422 are both provided with a V-shaped rectangular strip 402 on the side close to the lamp shade 12; the V-shaped opening of the rectangular strip 402 faces the notch of the V-shaped structure. In the length direction X of the lamp shell 1, the orthogonal projection of the rectangular strip 402 coincides with the orthogonal projection of the lamp outer shell 11, and the orthogonal projection of the rectangular strip 402 in the left plug 412 is tangent to one side of the orthogonal projection of the lamp shade 12, and the orthogonal projection of the rectangular strip 402 in the left plug 412 is tangent to the side of the orthogonal projection of the lamp shade 12 away from the rectangular strip 402 in the left plug 412; that is, in the length direction X of the lamp shell 1, the sum of the thickness of the rectangular strip 402 of the left plug 412, the thickness of the rectangular strip 402 of the right plug 422 and the length of the lamp shade 12 is equal to the length of the lamp outer shell 11. The rectangular strip 402 of the left plug 412 and the rectangular strip 402 of the right plug 422 are respectively in contact with the two ends of the lamp shade 12 in the length direction X of the lamp shell 1; the side of the left plug 412 away from the left clamping piece 411 is clamped to the groove-shaped cavity on one side of the first trapezoidal groove body through the rectangular strip 402 in the left plug 412 and is fixed by self-tapping screws, and the side of the right plug 422 away from the right clamping piece 421 is clamped to the groove-shaped cavity on the other side of the first trapezoidal groove body through the rectangular strip 402 in the right plug 422 and is connected by self-tapping screws.

[0083] Optionally, the width of the lower side plate 112 perpendicular to the length direction of the lamp shell 1 is 10 mm.

[0084] Specifically, if the width of the lower side plate 112 perpendicular to the length direction of the lamp shell 1 is less than 10 mm, the installation space of the lamp accessories (such as the lamp strip and the control panel 31) will be insufficient; if the width of the lower side plate 112 perpendicular to the length direction of the lamp shell 1 is greater than 10 mm, the cabinet body 01 (such as the cabinet body 01) will be occupied. Figure 22The lower side plate 112 is designed as 10mm along the width direction perpendicular to the length direction of the lamp shell 1, which not only avoids insufficient installation space of the lamp accessories (such as the lamp strip and the control panel 31), but also prevents occupying the space of the cabinet 01, and improves the appearance effect of the cabinet 01. Alternatively, the width of the upper side plate 111 along the width direction perpendicular to the length direction of the lamp shell 1 is less than the width of the lower side plate 112 along the width direction perpendicular to the length direction of the lamp shell 1.

[0087] Step S2, in combination with 2, Figure 8 and Figure 14 , the installation of the switch protection cover 32: the switch protection cover 32 is inserted from the side of the upper side plate 111 away from the lower side plate 112 to the direction of the lower side plate 112 along the width direction Y of the straight side plate 113, and the switch protection cover 32 passes through the inductive through hole 1111 and is clamped on the control panel 31, so as to complete the fixed connection of the control panel 31, the switch protection cover 32 and the housing 11.

[0088] Step S3, in combination with Figure 4 , Figure 5 and Figure 14 , the installation of the lamp strip 2: the lamp strip 2 is pasted on the lamp strip cavity 13 of the lamp housing 11 along the length direction X of the lamp shell 1, specifically on the second trapezoidal groove-shaped lower bottom surface of the lamp strip cavity 13.

[0089] Optionally, the fourth step of installation is performed after the third step is completed; the first, second and third steps can be implemented in reverse, and the present embodiment only takes the example of installing the control panel 31 first, then the switch protection cover 32, and finally installing the lamp strip 2, which does not limit the order of the three installation steps.

[0090] Step S4, combination Figure 6 and Figure 14 As shown in the figure, the installation of the lampshade 12: along one end of the lamp housing 11, one end of the lampshade 12 is slidably inserted into the U-shaped structure of the lamp housing 11, and is specifically inserted between the lamp strip 2 and the control panel 31, so that the median plane of the lampshade 12 perpendicular to its length direction is in the same imaginary plane as the median plane of the lamp housing 11 perpendicular to its length direction, and the first vertex angle of the lampshade 12 is in contact with the straight side plate 113 of the lamp housing 11; the first vertex angle is the vertex angle of the V-shaped structure.

[0091] Step S5, combination Figure 11 , Figure 12 and Figure 14 As shown in the figure, the installation of the left plug 412 and the right plug 422: the rectangular bars 402 of the left plug 412 and the right plug 422 face each other, the side of the left plug 412 close to the rectangular bar 402 is in contact with one end of the lamp housing 11 along the length direction X of the lamp housing 1, and is connected by a screw. The side of the right plug 422 close to the rectangular bar 402 is in contact with the other end of the lamp housing 11 along the length direction X of the lamp housing 1, and is connected by a screw.

[0092] Compared with the prior art, the drawer lamp for expanding the illumination angle provided by the present embodiment at least achieves the following beneficial effects:

[0093] First, through the drawer lamp for expanding the illumination angle provided by the present embodiment, energy and cost are saved while realizing large-range and dead-angle-free lighting; first, the present embodiment provides a herringbone-shaped lampshade 12, and the V-shaped structure is formed between part of the second side plate 123 and the first side plate 122, and the opening of the V-shaped structure is away from the straight side plate 113 side, so that the illumination of the lamp strip 2 in the lamp housing 11 can be refracted and reflected once through the lampshade 12, which can increase the illumination range of the light, and when the drawer lamp for expanding the illumination angle is applied to the cabinet body 01, the light is refracted into the deep dead angle of the cabinet body 01; further, part of the second side plate 123 has a corrugated surface, so that the light refracted by the first side plate 122 is reflected by the corrugated surface of the second side plate 123, and the reflected light can further enhance the illumination range of the lamp strip 2.

[0094] Secondly, the drawer lamp for expanding the irradiation angle can realize large-range and dead-angle-free lighting, and does not cause direct irradiation injury to the eyes of the user. Firstly, when the drawer lamp for expanding the irradiation angle is installed above the drawer opening, the light irradiated by the lamp strip 2 does not cause direct irradiation to the eyes of the user. Further, the corrugated surface of the second side plate 123 further scatters the light in the secondary refraction process, so that the light irradiation intensity near the cabinet door can be effectively reduced, thereby enhancing the softness of the light.

[0095] Thirdly, the drawer lamp for expanding the irradiation angle is light and thin in volume, and is convenient to install. Firstly, the structure of the herringbone-shaped lampshade 12 is optimized, so that the actual use length of the lamp strip 2 can be effectively reduced, and the large-power lamp beads required by the corresponding lighting requirements are required. The overall weight of the drawer lamp for expanding the irradiation angle can be effectively reduced, so that it is lighter and thinner. Further, part of the second side plate 123 in the lampshade 12 is a corrugated surface structure, which can perform secondary scattering and reflection on the light, so as to increase the light irradiation range, and the volume can be further reduced by simplifying the mechanism.

[0096] In an alternative embodiment, continuing to refer to Figure 2 and Figure 15 shown, Figure 15 is the circuit logic diagram of the drawer lamp for expanding the irradiation angle provided by the present application. In the present embodiment, the control assembly 3 further comprises a transformer 35 arranged in the control cavity 14. The control board 31 comprises an induction switch 313 and a circuit board 312.

The induction switch 313 is integrated on the circuit board 312. The circuit board 312 is electrically connected to the transformer 35 through an external lead 406 at one end along the length direction X of the lamp shell 1, and is electrically connected to the lamp strip 2 through an internal lead 405 at the other end. The induction switch 313 is arranged in the switch protection cover 32.

[0097] Specifically, the control board 31 comprises an induction switch 313 and a circuit board 312. The induction switch 313, the lamp strip 2, the transformer 35 and the circuit board 312 are electrically connected.

[0098] The above-mentioned induction switch 313 is an infrared sensor, which can be specifically of the type HW-50. The induction switch 313 is integrated and welded on the circuit board 312, and is received in the control cavity 14 together with the circuit board 312. The induction switch 313 is used to sense the change of the drawer switch.

[0099] The circuit board 312 is a rectangular plate body, which is used to mechanically support the induction switch 313 and receive the induction information from the induction switch 313 to instruct the light strip 2 to open and close. That is, the induction switch 313 is integrated on the circuit board 312, which can sense the opening and closing of the drawer switch to make the power on and off instruction, and the lamp line is welded at both ends of the circuit board, one end is connected to the transformer for power supply, and the other end is connected to the light strip 2 for power supply. The circuit board 312 is composed of insulating material and conductive material, and the conductive line is laid on the insulating material to realize the sensing of the opening and closing of the drawer and the control of the power on and off. The model of the circuit board 312 can be D24V08CA02. The length extension direction of the circuit board 312 is along the length direction X of the lamp shell 1, and the width extension direction of the circuit board 312 is along the width direction Z of the lower side plate 112. Along the length direction X of the lamp shell 1, the circuit board 312 is inserted and clamped and fixed in the control cavity 14.

The model of the transformer 35 can be K24V65CA03. The other end of the transformer 35 away from the circuit board 312 is connected with the external power supply socket 33.

[0101] Through the above scheme, the control board 31 can receive the reading of the light signal and further control the opening and closing of the light strip 2. At the same time, the transformer 35 can convert the power supply voltage, and supply the light strip 2 with electric energy through the circuit board 312, so that when the cabinet 01 is pulled open, the light strip 2 in the drawer cabinet automatically turns on, and when the drawer is pulled back to close, the light strip 2 in the drawer cabinet automatically turns off.

[0102] In an alternative embodiment, continuing to refer to Figure 2 and Figure 3 As shown, the oblique side plate 114 is provided with a lower electric plate clamping groove recessed away from the straight side plate 113 on the side close to the straight side plate 113, and the lower electric plate clamping groove is located at one end of the oblique side plate 114 close to the second side plate 123; the straight side plate 113 is provided with an upper electric plate clamping groove recessed away from the oblique side plate 114 on the side close to the oblique side plate 114; along the width direction Z of the lower side plate 112, the orthographic projection of the upper electric plate clamping groove and the orthographic projection of the lower electric plate clamping groove coincide with each other; the lower electric plate clamping groove and the upper electric plate clamping groove are both U-shaped grooves;

This insertion and installation can save the installation cost caused by the use of connecting pieces, and the reduction of the use of connecting pieces can optimize and reduce the overall structure, make the connection more compact and concentrated, and further make the device more light, thin and small.

After the rectangular strip 402 abuts against the lampshade 12, the through flat corner is parallel to the inclined side plate 114, and the lamp strip cavity 13 and the control cavity 14 form a gap between the through flat corner, so that the through lamp strip cavity 13 and the control cavity 14 can be connected.

The other end of the outer lead wire 406 away from the transformer 35 is connected to the 220V power socket 33 outside the lamp housing to obtain power. The outer lead wire 406 is also an electric energy transmission wire.

[0130] In an alternative embodiment, continuing to refer to Figure 20 and Figure 21 as shown, Figure 21 is a structural schematic view of the left plug provided by the application; one end of the pin piece 4082 close to the upper side plate 111 is provided with a rectangular limiting piece 4083, and a T-shaped structure is formed between the limiting piece 4083 and the pin piece 4082; one side of the limiting piece 4083 close to the trapezoidal piece 4081 is connected with the side of the trapezoidal piece 4081 close to the pin piece 4082, and a second L-shaped structure is formed between the limiting piece 4083 and part of the trapezoidal piece 4081; one side of the limiting piece 4083 close to the upper side plate 111 is located in the same plane as the side of the trapezoidal piece 4081 close to the upper side plate 111.

[0131] One side of the pin piece 4082 close to the straight side plate 113 is provided with an arc-shaped convex point 4084, the convex point 4084 protrudes away from the pin piece 4082, and the orthographic projection of the convex point 4084 completely coincides with the orthographic projection of the trapezoidal piece 4081 along the length direction X of the lamp shell 1.

[0132] One side of the left plug 412 and the right plug 422 close to the pin piece 4082 is provided with a limiting clamping groove matched with the limiting piece 4083, the limiting clamping groove is a rectangular groove recessed toward the lamp outer shell 11, and the limiting clamping groove is coplanar with the left plug 412 and the right plug 422 parallel to the two sides of the straight side plate 113 and the upper side plate 111; one side of the limiting clamping groove close to the straight side plate 113 is provided with a recessed point 4085 matched with the convex point 4084, the limiting piece 4083 is clamped into the limiting clamping groove, and the convex point 4084 is clamped into the recessed point 4085.

[0133] Specifically, the pin piece 4082 is vertically connected with a rectangular limiting piece 4083 near one end of the upper side plate 111, and the limiting piece 4083 is integrally formed between the pin piece 4082. The limiting piece 4083 and the pin piece 4082 form a T-shaped structure parallel to the trapezoidal piece 4081. The limiting piece 4083 is vertically connected with the trapezoidal piece 4081 near a side of the trapezoidal piece 4081 close to the pin piece 4082, and forms a second L-shaped structure between the limiting piece 4083 and part of the trapezoidal piece 4081; the limiting piece 4083 close to a side of the upper side plate 111 is in the same plane as the side of the trapezoidal piece 4081 close to the upper side plate 111, and the limiting piece 4083 close to a side of the straight side plate 113 is in the same plane as the side of the trapezoidal piece 4081 close to the straight side plate 113.

[0134] The left plug 412 and the right plug 422 are both provided with a limiting clamping groove matching the limiting piece 4083 near a side of the pin piece 4082. The limiting clamping groove is a rectangular groove, and the groove opening is recessed towards the lamp housing 11. The limiting clamping groove close to a side of the upper side plate 111 is in the same plane as the side of the trapezoidal piece 4081 close to the upper side plate 111, and the limiting clamping groove close to a side of the straight side plate 113 is in the same plane as the side of the trapezoidal piece 4081 close to the straight side plate 113; that is, the limiting clamping groove is coplanar with the left plug 412 and the right plug 422 parallel to the two sides of the straight side plate 113 and the upper side plate 111.

[0135] Further, after the limiting piece 4083 of the pin piece 4082 is clamped into the limiting clamping groove along the lower side plate 112 towards the upper side plate 111, the pin piece 4082 can still return along the original path and fall out of the limiting clamping groove. Therefore, the pin piece 4082 is further provided with an arc-shaped protrusion 4084 near a side of the straight side plate 113, and the limiting clamping groove is further provided with a recessed point 4085 matching the protrusion 4084 near a side of the straight side plate 113. The arc-shaped protrusion 4084 can be an arc-shaped body or a semi-arc-shaped body (such as a semi-cylindrical body), and the present embodiment takes the semi-cylindrical body as an example; the length direction of the semi-cylindrical protrusion 4084 is the length direction X of the lamp housing 1; the arc-shaped surface of the protrusion 4084 protrudes towards the side away from the pin piece 4082. Along the length direction X of the lamp housing 1, the orthogonal projection of the protrusion 4084 completely coincides with the orthogonal projection of the pin piece 4082. In the present embodiment, the recessed point 4085 is a semi-cylindrical groove matching the semi-cylindrical protrusion 4084; when the user pushes the lamp housing 1 and the left plug 412 and the right plug 422 at both ends to the maximum limit along the direction of the cabinet door from the deep part of the cabinet body 01, the protrusion 4084 and the recessed point 4085 are clamped in the recessed and protruding matching mode, and at this time, along the length direction X of the lamp housing 1, the orthogonal projection of the protrusion 4084 completely coincides with the orthogonal projection of the trapezoidal piece 4081.

[0136] When the user pushes the lamp shell 1 and the left plug 412 and the right plug 422 at the two ends along the depth of the cabinet body 01 to the direction of the cabinet door, the pin 4082 of the left clamping piece 411 can be slidably inserted into the left rectangular groove 4121 of the left plug 412, and the pin 4082 of the right clamping piece 421 can be slidably inserted into the right rectangular groove 4221 of the right plug 422. When sliding to the maximum limit, the limiting clamps on the left clamping piece 411 are clamped into the limiting clamp grooves of the left clamping piece 411, and the limiting clamps on the right clamping piece 421 are clamped into the limiting clamp grooves of the right clamping piece 421, so that the lamp shell 1 and the left plug 412 and the right plug 422 at the two ends cannot be continuously pushed along the depth of the cabinet body 01 to the direction of the cabinet door, thereby achieving the installation limitation of the drawer lamp for expanding the illumination angle of the embodiment. Further, after the pin 4082 of the left clamping piece 411 is inserted into the left rectangular groove 4121 of the left plug 412, and after the pin 4082 of the right clamping piece 421 is inserted into the right rectangular groove 4221 of the right plug 422, it is still easy to fall off from the opposite direction of the insertion direction. The pins 4082 of the left clamping piece 411 and the right clamping piece 421 are provided with protrusions 4084, and the left plug 412 and the right plug 422 are provided with recesses 4085 matched with the protrusions 4084. The concave-convex matching of the protrusions 4084 and the recesses 4085 can prevent the drawer lamp for expanding the illumination angle from sliding in the opposite direction of the insertion direction.

[0137] In an alternative embodiment, continuing to refer to Figures 2-14 As shown, the upper side plate 111 and the inclined side plate 114 are connected through a side corner, and the left plug 412, the right plug 422, the left clamping piece 411, and the right clamping piece 421 are connected through corners corresponding to the side corner, and the corners are provided with chamfered planes.

[0138] Specifically, the drawer lamp for expanding the illumination angle of the embodiment, the upper side plate 111 and the inclined side plate 114 are connected through a side corner, and the side corner extends in the length direction X of the lamp shell 1. Along the length direction X of the lamp shell 1, the left plug 412 and the right plug 422 are provided with chamfered planes corresponding to the side corner, and the two ends of the side corner are in contact with the chamfered planes of the left plug 412 and the right plug 422.

[0139] The corners corresponding to the side corner, the right plug 422, the left clamping piece 411, and the right clamping piece 421 are processed to form chamfered planes; that is, the corners near the side of the cabinet door of the drawer lamp for expanding the illumination angle of the embodiment are processed to form chamfered planes.

[0140] Through the above scheme, the user can reduce the risk of bumping damage with the drawer lamp for expanding the illumination angle of the embodiment when opening the cabinet door, so that the cabinet door is a smooth chamfered plane even when bumping, thereby effectively reducing the bumping damage during use.
