DETAILED DESCRIPTION
[0024] The following is combined with Figures 1 to 7 The utility model is described in detail.
[0025] The utility model is a ring-type LED light bulb, comprising a lamp holder 1 and a bulb shell 2, wherein the lamp holder 1 is fixedly connected to the bulb shell 2, and further comprises a support plate 3, a first metal support wire 4, a second metal support wire 5 and a plurality of LED lamp beads 6, wherein the support plate 3, the metal support wire and the plurality of LED lamp beads 6 constitute a wick assembly of the light bulb; Figure 1 As shown, the multiple LED lamp beads 6 are electrically connected in sequence and are dispersedly arranged in a ring shape inside the bulb 2, and the lighting directions of adjacent LED lamp beads 6 are different; the support plate 3 is arranged at the mouth of the bulb 2, and the first metal support wire 4 and the second metal support wire 5 are both arranged on the support plate 3, one end of the first metal support wire 4 and the second metal support wire 5 are electrically connected to the LED lamp beads 6, and the other end is electrically connected to the lamp holder 1, the two metal support wires and the multiple LED lamp beads 6 form a complete electrical circuit so that the bulb can emit light normally.
[0026] The utility model has the following advantages: 1. The LED lamp beads are dispersed and surrounded inside the bulb, which is beneficial to the heat dissipation between the lamp beads and prolongs the service life of the bulb; 2. A plurality of LED lamp beads are connected and arranged in a three-dimensional pentagonal shape inside the bulb, which can irradiate light in five different directions at the same time to form a star-shaped light effect. The bulb is more decorative and has diversified decorative effects, meeting the diverse decorative needs of users; 3. The overall structure of the bulb is novel and simple, and the preparation cost is low.
[0027] The light bulb of the present technical solution also includes a conductive wire 7, and the multiple LED lamp beads 6 are electrically connected through the conductive wire 7; the width of the first metal support wire 4 and the second metal support wire 5 is greater than the width of the conductive wire 7, so that the supporting force of the metal support wire is greater, so as to support the LED lamp beads 6 to be installed in a stable three-dimensional shape inside the bulb shell 2. At the same time, the small width of the conductive wire 7 can weaken the presence of the conductive wire 7 and avoid affecting the shape and aesthetics of the light bulb.
[0028] Preferably, the first metal support wire 4 or the second metal support wire 5 is provided with a resistor 41 to improve the safety performance of the light bulb and extend its service life. The resistor 41 of the technical solution can be a chip resistor 41, which is lighter, more compact and more convenient to assemble.
[0029] As an embodiment, the support plate 3 is provided with at least two wire holes 31 for the metal support wire to pass through. The support plate 3 is mainly used to support the metal support wire to stand inside the bulb 2. To increase the connection strength between the support plate 3 and the metal support wire, the wire hole 31 can be set as a blind hole, which is pierced by the metal support wire.
[0030] In addition to dispersing the lamp beads to facilitate heat dissipation, the technical solution can also set a plurality of heat dissipation holes 32 on the support plate 3. The heat dissipation holes 32 are distributed in a ring shape on the outer circle side of the wire hole 31 and distributed below the LED lamp beads 6 to transfer the heat inside the bulb 2 in time.
[0031] Preferably, the outer peripheral edge of the support plate 3 is provided with an inclined portion 33, and the inclined portion 33 makes the support plate 3 like a plug inserted into the mouth of the bulb shell 2. It can prevent the support plate 3 from falling into the bulb shell 2, and facilitate the assembly of the support plate 3. At the same time, the connection between the assembled support plate 3 and the mouth of the bulb shell 2 is more firmly established.
[0032] To further improve the technical solution, the lamp holder 1 includes a metal shell 11, an external threaded portion 12 is provided on the outer side of the metal shell 11, a receiving cavity 13 with an opening is provided at one end of the metal shell 11, and an end plate 14 is provided at the other end of the metal shell 11; it also includes a conductive rivet 15 and a plastic insulating member 16 connected to the end plate 14 and used to prevent the end plate 14 from being concave and deformed, and the plastic insulating member 16 is located on the center line of the metal shell 11; the plastic insulating member 16 is provided with an assembly hole 161, and the assembly hole 161 is communicated with the receiving cavity 13; the conductive rivet 15 is assembled in the assembly hole 161.
[0033] The lamp holder 1 of the utility model is different from the traditional lamp holder 1 which is not environmentally friendly and easy to deform. The plastic insulating part 16 is used to replace the glass insulating layer at the bottom of the traditional lamp holder 1, and the conductive rivet 15 is assembled on the top of the plastic insulating part 16 for conduction. The conductive rivet 15 replaces the traditional conductive tin layer. The lamp holder 1 no longer needs to use impure glass materials and flux with greater safety hazards, which effectively promotes the green and environmentally friendly production of lamps and can simplify the processing steps of lamps. There is no need to perform cumbersome soldering processes, which reduces the production cost of lamps to a certain extent. On the other hand, the plastic insulating part 16 is used to strengthen the structure of the end plate 14, improve the stability of the end plate 14, and strengthen the endurance performance of the end plate 14. On the basis of not increasing the production cost, the lamp holder 1 has the function of preventing concave deformation.
[0034] As an embodiment, a mounting hole 141 is provided in the middle of the end plate 14, and the plastic insulating member 16 is disposed in the mounting hole 141. The plastic insulating member 16 of the present technical solution is formed in the middle of the end plate 14 by one-piece injection molding. After the metal shell 11 is manufactured, the injection mold extends into the metal shell 11, and the plastic insulating member 16 is integrally injection molded on the end plate 14. Compared with directly pressing the plastic insulating member 16 into the top of the metal shell 11 for tight assembly, the one-piece injection molding process is simpler, and at the same time, the connection between the plastic insulating member 16 and the end plate 14 can be more stable without damaging the plastic insulating member 16.
[0035] Preferably, the plastic insulating member 16 includes an upper assembly portion 162 and a lower assembly portion 163 connected to each other, wherein the upper assembly portion 162 is fitted on the inner side of the end plate 14, and the lower assembly portion 163 is fitted on the outer side of the end plate 14, and the upper assembly portion 162 and the lower assembly portion 163 cover the inner and outer sides of the end plate 14 to improve the anti-deformation performance of the end plate 14. A first annular assembly groove 164 is further provided between the upper assembly portion 162 and the lower assembly portion 163, and the end plate 14 is accommodated in the first annular assembly groove 164 during injection molding.
[0036] In order to further improve the anti-deformation performance of the lamp holder 1, the upper assembly part 162 and the lower assembly part 163 completely cover the inner and outer areas of the end plate 14, that is, the covering area of the upper assembly part 162 and the lower assembly part 163 just exceeds or exceeds the boundary of the end plate 14, and the plastic insulating part 16 is molded at the connection between the end plate 14 and the first annular side wall, so that the end plate 14 can obtain the support force of the first annular side wall during the assembly process into the lamp holder, and the anti-deformation performance of the end plate 14 is further improved.
[0037] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
