Description
Technical Field
[0001] The utility model relates to the technical field of lighting fixtures, and more specifically to a filament light source component, a filament light string and a filament bulb. Background Art
[0002] LED lamps occupy a huge share in the lighting market, and filament LED lamps are favored by customers because of their retro, casual, romantic and unique lighting effects.
[0003] The production process of LED filament lamps on the market is extremely complicated, the cost is high, and there are reliability and quality risks. The reasons are as follows: First, the existing LED filament light source needs to be supported by a wire bracket, and the filament light source needs to be connected to the wire bracket by welding or spot welding to form a loop and support for the filament light source; second, after the existing filament light source is welded or spot welded to the wire bracket, the wire bracket needs to be welded or spot welded to a thinner wire, and the thin wire is used as a lead to be electrically connected to the lamp holder; third, the existing LED filament light source requires an external resistor, using a resistor with lead pins, one end of the lead pin is welded to the wire bracket, and the other end of the resistor lead is electrically connected to the lamp holder; fourth, the wire bracket of the existing filament light source passes through the plastic fixing After that, the plastic parts need to be squeezed to make the plastic parts clamp the iron wire; fifth, the existing LED filament light source uses a ceramic plate as a substrate, and the ceramic substrate is very easy to break, so the light source with a ceramic substrate is very easy to break during transportation and assembly application, resulting in low production yield; sixth, after the existing LED filament light source is butt-welded or spot-welded with the iron wire bracket, the tension and stress of the iron wire bracket cause the connection solder joints between the bracket and the light source to become desoldered; seventh, if the pin position of the existing LED filament light source and the iron wire bracket is contaminated or the coating is oxidized, it will cause the welding to be loose, and it will be very easy to have desoldering and false welding problems. It can be seen from this that the assembly process of the existing LED filament bulbs is complicated and cumbersome, with low production efficiency and yield, and there are great risks in product quality reliability; eighth, because the light source of the existing filament bulb needs to be supported by an iron wire bracket, the iron wire bracket blocks the light output of the light source, resulting in a dark area and shadow area for filament bulb products with colored shells.

[0042] Reference Figure 5 The second embodiment of the filament lamp string described in the present application is different from the first embodiment in that the lamp holder 400 and the plastic fixing part 200 in the second embodiment of the filament lamp string are integrated. In this embodiment, it is not necessary to design the channel 210 of the plastic fixing part 200 as a connected limit portion 211 and abutment portion 212. At this time, the fiberglass board 100 can only be inserted into the channel 210 from the upper end of the plastic fixing part 200. In this embodiment, the so-called lamp holder 400 and the plastic fixing part 200 are integrated, which means that the lamp holder 400 and the plastic fixing part 200 are first installed together to form a whole. The installation method between the two can be screw-on fixation, snap-on fixation, direct insertion, etc. Of course, before the lamp holder 400 and the plastic fixing part 200 are installed together, the assembly between the conductive column 600 and the plastic fixing part 200 needs to be completed first.
[0043] Reference Figure 6 The present application also discloses a filament light bulb, a first embodiment of which includes a lamp holder 700, a bulb shell 800, two conductive filaments 900 and a first embodiment of the filament light source assembly, wherein the conductive filament 900 serves as the conductive terminal, the plastic fixing member 200 is installed at the bottom position inside the bulb shell 800 so that the fiberglass board 100 is placed inside the bulb shell 800, the top end of the lamp holder 700 is fixed at the bottom position outside the bulb shell 800, the top ends of the two conductive filaments 900 are placed in the plug-in space of the filament light source assembly so that one end of the two conductive filaments 900 is connected to the positive electrode pad 120 and the negative electrode pad 110 one by one, and the bottom ends of the two conductive filaments 900 are electrically connected to the lamp holder 700 respectively.
[0044] Further as a preferred implementation, in this embodiment, the upper end surface of the plastic fixing part 200 is provided with two limiting grooves 220, the conductive wire 900 includes a mounting section 910 and a joining section, one end of the mounting section 910 is connected to one end of the joining section and the mounting section 910 and the joining section are perpendicular to each other, the mounting section 910 of the conductive wire 900 is placed in the limiting groove 220 of the plastic fixing part 200, and the joining section of the conductive wire 900 is placed in the plug-in space of the filament light source assembly.
[0045] Reference Figure 7 As a further preferred embodiment, in order to further improve the convenience of light bulb assembly in this embodiment, the structure of the plastic fixing part 200 is specially designed. First, a guide protrusion 230 is provided on the outer side of the plastic fixing part 200 in this embodiment along its axial direction. The guide protrusion 230 is provided with two guide protrusions 230, which are symmetrically arranged on the outer side of the plastic fixing part 200. The outer side of the guide protrusion 230 is in an arc shape, and the top of the guide protrusion 230 is provided with an inclined surface. The setting of the guide protrusion 230 facilitates the plastic fixing part 200 to be quickly and accurately inserted from the bottom of the bulb shell 800. The plastic fixing part 200 in this embodiment does not need to design its channel 210 as a connected limiting portion 211 and abutting portion 212. The middle position of the channel 210 of the plastic fixing part 200 is divided into an upper half 213 and a lower half 214 by a partition. The upper half 213 of the channel 210 is a flat rectangular parallelepiped, and the lower half 214 of the channel 210 is cylindrical. The partition is provided with two through holes 215 connecting the upper half 213 and the lower half 214 of the channel 210, and the lower end surface of the partition is provided with a cylindrical guide column 216 at the position of the through hole 215. During the actual assembly process, the welding pad section 150 of the fiberglass board 100 is inserted into the upper part 213 of the channel 210 of the plastic fixing part 200. The gap between the functional surface of the fiberglass board 100 and the upper part 213 of the channel 210 is the plug-in space. The joining section of the conductive wire 900 passes through the through hole 215 of the channel 210 and is electrically connected to the lamp holder 700.
[0046] As a further preferred embodiment, in this embodiment, the entire plastic fixing part 200 is placed inside the bulb 800, and the distance from the bottom end of the plastic fixing part 200 to the bottom end of the bulb 800 is 0.5 mm to 2 mm, and the area below the plastic fixing part 200 in the bulb 800 is coated with glue. This design is suitable for E12 type lamp holders and E17 type lamp holders. The main reason is that the filament bulbs of E12 type lamp holders and E17 type lamp holders have poor waterproof effects. If the above design is not performed, the filament bulbs are easy to absorb water vapor in the environment, which is easy to reduce the service life of the filament bulbs and easily affect the lighting effect of the filament bulbs. It should be noted that the above design is not only applicable to the cases of E12 type lamp holders and E17 type lamp holders, but can also be applied to the cases of other types of lamp holders (such as E27 type lamp holders). However, considering the actual application requirements, the above two cases require a sinking structure design of the plastic fixing part 200. In addition, in this embodiment, the area below the plastic fixing member 200 in the bulb shell 800 may be coated with glue depending on the actual application. Coating the area below the plastic fixing member 200 in the bulb shell 800 with glue is more conducive to achieving waterproof and moisture-proof effects.
[0047] The above are only preferred embodiments of the present invention, and do not limit the patent scope of the present invention. All equivalent structural changes made under the concept of the present invention using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
