Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0034] The present invention relates to a novel structure for connecting a radiator of a high-power bulb lamp and a lamp holder plastic part, including a lamp holder plastic part 100 and a heat dissipation fin group 200.

[0035] Such as Figure 1 、 Figure 2 、 Figure 3 And Figure 4As shown, the lamp holder plastic part 100 is in the shape of a bulb. The axial direction of the lamp holder plastic part 100 is defined as the vertical direction, and the radial direction of the lamp holder plastic part 100 is defined as the horizontal direction. Both ends of the lamp holder plastic part 100 are open axially. In the illustrated direction, the upper opening of the lamp holder plastic part 100 serves as the installation opening 102, and the lower opening of the lamp holder plastic part 100 serves as the light projection opening 101. The installation opening 102 and the light projection opening 101 are coaxially arranged. The opening diameter of the light projection opening 101 is larger than the opening diameter of the installation opening 102. An installation cavity 110 is provided inside the lamp holder plastic part 100. The installation cavity 110 communicates with both the installation opening 102 and the light projection opening 101. A positioning wall 120 is provided on the lamp holder plastic part 100. The positioning wall 120 can be provided on the outer wall of the lamp holder plastic part 100. In this embodiment, the positioning wall 120 can be provided in the installation cavity 110. The positioning wall 120 is in a circular ring shape and can be coaxially arranged in a circular ring shape close to and surrounding the installation opening 102. The positioning wall 120 extends downward along the vertical direction from the upper part of the installation cavity 110. The lamp holder plastic part 100 can be made of plastic, and the positioning wall 120 is integrally formed on the lamp holder plastic part 100. The area surrounded by the positioning wall 120 is defined as the fixing area 121, that is, the fixing area 121 is located in the installation cavity 110. A plurality of positioning grooves 122 are provided on the positioning wall 120, and the positioning grooves 122 are sequentially distributed along the circumferential direction of the positioning wall 120. The positioning grooves 122 extend in the vertical direction, and the lower ends of the positioning grooves 122 penetrate through to the lower end surface of the positioning wall 120. A plurality of hooks 130 extend vertically downward from the top of the installation cavity 110. Each hook 130 is located in the fixing area 121. The number of the positioning grooves 122 and the hooks 130 is the same, and the positioning grooves 122 and the hooks 130 are aligned one by one, and one positioning groove 122 is close to one hook 130. As Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 8 shown, the heat dissipation fin group 200 is installed in the installation cavity 110. The heat dissipation fin group 200 includes a plurality of A fins 210 and a plurality of B fins 220. The number of the A fins 210 can be more than the number of the B fins 220. The number of the B fins 220 is the same as the number of the positioning grooves 122, or the number of the B fins 220 is less than the number of the positioning grooves 122. In this embodiment, as Figure 4 and Figure 5As shown, four positioning grooves 122 are provided, four B fins 220 are correspondingly provided, and four hooks 130 are correspondingly provided. Both the A fins 210 and the B fins 220 are vertically placed in the installation cavity 110. And a plurality of A fins 210 and a plurality of B fins 220 are distributed at intervals around the same axis 201, and the axis 201 is a virtual line in space. This axis 201 coincides with the central axis of the lamp head plastic part 100. The B fin 220 is located between two A fins 210. The A fins 210 and the adjacent A fins 210 and between two adjacent A fins 210 can be relatively fixed by welding, gluing, etc. to form a heat dissipation fin group 200. The A fin 210 includes a first body 211, and the B fin 220 includes a second body 221. Each first body 211 and second body 221 are distributed around the axis 201, and the first body 211 and the second body 221 are vertically arranged. The upper sides of each first body 211 and second body 221 can be in the same horizontal plane. After the first body 211 enters the installation cavity 110, it is inserted upward into the fixing area 121, and the outer side (the side away from the axis 201) of each first body 211 approaches or abuts against the inner side surface of the positioning wall 120 in the horizontal direction. Each second body 221 is paired with the positioning groove 122 in one-to-one position, and the second body 221 can be inserted into the positioning groove 122 vertically from bottom to top. A first bayonet 222 is provided on the second body 221. When the second body 221 is inserted into the positioning groove 122 and continues to move upward, the hook 130 can be snapped into the first bayonet 222 to fix the second body 221. As Figure 3 As shown, when the heat dissipation fin group 200 is installed in the installation cavity 110, the positioning cooperation between the second body 221 of the B fin 220 and the positioning groove 122 assists the quick alignment and snap connection between the first bayonet 222 and the hook 130, restricting the second body 221 from vertically disengaging from the positioning wall 120, and further fixing the heat dissipation fin group 200 in the installation cavity 110 in the vertical direction. At the same time, the outer sides of each first body 211 are limited by the positioning wall 120, that is, the upper part of the heat dissipation fin group 200 is limited in the horizontal direction by the positioning wall 120. In this way, the heat dissipation fin group 200 is quickly positioned and fixed in the installation cavity 110. During actual use, the light source (light-emitting part) of the bulb lamp can be installed at the light projection port 101, and the generated light irradiates outward from the light projection port 101. Most of the heat generated when the light source emits light is heat-exchanged with the heat dissipation fin group 200, and the heat dissipation fin group 200 and the lamp head plastic part 100 are used to dissipate heat.

[0036] In some specific embodiments of the present invention, such as Figure 4 、 Figure 5 and Figure 6As shown, a plurality of positioning grooves 122 are evenly distributed at equal intervals on the positioning wall 120. The number and positions of the positioning grooves 122, the hooks 130, and the B fins 220 are paired one by one. In this embodiment, the positioning wall 120 is annular, and four positioning grooves 122 are provided on the positioning wall 120, with a 90° interval between adjacent positioning grooves 122. Correspondingly, four hooks 130 are provided in the installation cavity 110, and the four hooks 130 are evenly distributed. The heat dissipation fin group 200 is provided with four B fins 220, and the four B fins 220 are evenly distributed around the axis 201, with a 90° interval between adjacent B fins 220. The number of the positioning grooves 122, the hooks 130, and the B fins 220 can also be set to two, four, or more.

[0037] In some embodiments of the present utility model, as Figure 2 , Figure 4 and Figure 9 shown, the axial two ends of the lamp head plastic part 100 are respectively a light projection port 101 and an installation port 102 which are coaxially arranged. The positioning wall 120 is arranged around the installation port 102. There is an interval between the inner sides (the side close to the axis 201) of the A fins 210 and the B fins 220, and a wire passing space 230 is defined at the interval. The wire passing space 230 is coaxially communicated with the installation port 102. The light source can be a lamp board, the lamp board is installed at the light projection port 101, and the wires of the lamp board pass through the wire passing space 230 and are connected to the installation port 102, and a threaded conductive head or other conductive parts can be installed at the installation port 102.

[0038] In some specific embodiments of the present utility model, as Figure 6 , Figure 7 , Figure 8 and Figure 9 shown, both the A fins 210 and the B fins 220 include a third body 240. The third body 240 is vertically placed, and the first body 211 extending from the upper side of the third body 240 constitutes the A fin 210, and the second body 221 extending from the upper side of the third body 240 constitutes the B fin 220. The length of the first body 211 in the horizontal direction is less than the length of the third body 240 in the horizontal direction, so that a first stepped opening 212 is formed between the outer side (the side far from the axis 201) of the first body 211 and the corresponding third body 240, and the first stepped opening 212 is L-shaped. During installation, as Figure 3As shown, when the first sheet body 211 is inserted into the fixing area 121, the vertical edge (the outer edge of the first sheet body 211) of the first stepped opening 212 abuts against the inner wall of the positioning wall 120, and the horizontal edge (the upper edge of the third sheet body 240) of the first stepped opening 212 abuts against the lower end surface of the positioning wall 120, thereby restricting the insertion depth of the A fin 210 relative to the fixing area 121, which is equivalent to restricting the insertion depth of the heat dissipation fin group 200 relative to the installation cavity 110. A W-shaped second stepped opening 223 is formed between the outer side (the side away from the axis 201) of the second sheet body 221 and the upper side of the corresponding third sheet body 240, that is, the second stepped opening 223 has two layers of steps in the vertical direction, and the middle part of the second stepped opening 223 is inserted and aligned with the positioning groove 122. Among them, a second bayonet 213 may also be provided on the first sheet body 211. A hook 130 aligned with the second bayonet 213 may be further provided in the installation cavity 110, and the vertical stability of the heat dissipation fin group 200 installed in the installation cavity 110 is further improved by the snap connection between the hook 130 and the second bayonet 213.

[0039] Among them, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a plurality of heat dissipation slots 140 are provided on the circumferential side wall of the lamp cap plastic part 100. The heat dissipation slots 140 are distributed along the circumference of the lamp cap plastic part 100 and extend in the vertical direction. On the inner wall of the installation cavity 110 at the corresponding positions between adjacent heat dissipation slots 140, a sliding groove 150 is provided. The sliding groove 150 extends in the vertical direction. When the heat dissipation fin group 200 is inserted, the side of the first sheet body 211 away from the axis 201 is slidably connected to the sliding groove 150 in a one-to-one matching manner. The heat dissipation slots 140 can connect the installation cavity 110 to the outside of the lamp cap plastic part 100 along the radial direction of the lamp cap plastic part 100. At the same time, the heat dissipation slots 140 are in one-to-one alignment and communication with the intervals between the adjacent third sheet bodies 240, and the heat dissipation slots 140 accelerate the air flow in the intervals between the third sheet bodies 240, further improving the heat dissipation effect of the heat dissipation fin group 200.

[0040] In some specific embodiments of the present invention, as Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10As shown in the figure, a bending portion 250 is provided on the lower side (the side away from the positioning wall 120) of each third sheet body 240. The bending portion 250 includes a fourth sheet body 251 and a fifth sheet body 252. The fourth sheet body 251 is bent horizontally from one side of the third sheet body 240, that is, the fourth sheet body 251 and the third sheet body 240 are perpendicular to each other. The fifth sheet body 252 is bent vertically upward (towards the side where the positioning wall 120 is located) from the side of the fourth sheet body 251 away from the third sheet body 240. The fourth sheet body 251 and the fifth sheet body 252 are perpendicular to each other. The fifth sheet body 252 corresponding to each third sheet body 240 is attached to the side surface of another adjacent third sheet body 240. That is, between two adjacent third sheet bodies 240, the fifth sheet on one of the third sheet bodies 240 is attached to the other third sheet body 240. The interval between two adjacent third sheet bodies 240 is fan-shaped in the horizontal direction, and the fourth sheet body 251 is fan-shaped to match the shape of the interval. By using the fourth sheet body 251 and the fifth sheet body 252, a stable interval size between adjacent third sheet bodies 240 is ensured. At the same time, when the light source is a lamp board, the lamp board is horizontally installed at the light projection port 101, and the upper side surface of the lamp board is attached to each fourth sheet body 251, and heat is transferred to the third sheet body 240 through the fourth sheet body 251 for heat dissipation.

[0041] Furthermore, a sixth sheet body 260 extends horizontally from the outer side (the side away from the axis 201) of the fourth sheet body 251, which is equivalent to the sixth sheet body 260 extending horizontally in the radial direction of the heat dissipation fin group 200 from the outer side of the fourth sheet body 251, and the sixth sheet body 260 is perpendicular to the third sheet body 240. The sixth sheet body 260 can be lapped on the lower end of the sliding groove 150. After the heat dissipation fin group 200 is installed in the installation cavity 110, the lower end of the heat dissipation fin group 200 is limited at the lower end of the sliding groove 150. Each fourth sheet body 251 is on the same horizontal plane to ensure good thermal conduction with the upper side surface of the lamp board.

[0042] In some specific embodiments of the present invention, as Figure 2 and Figure 3 shown, a plurality of perspective holes 160 are formed in the lamp head plastic part 100. The perspective holes 160 communicate with the fixing area 121, and the perspective holes 160 are in one-to-one correspondence with the positions of the hooks 130. During installation, it is possible to directly observe whether the hooks 130 are properly engaged with the first bayonet 222 through the perspective holes 160.
