Description

Technical Field

[0001] The utility model relates to the technical field of lamps, in particular to an LED bulb with a glass tube. Background Art

[0002] As a lighting device, light bulbs provide great convenience for human life and production, and have become one of the indispensable objects for human survival.

[0003] Existing tungsten filament bulbs usually include a glass shell and multiple tungsten filaments encapsulated inside the glass shell. When the power is turned on, the current flows through the tungsten filaments and the tungsten filaments are affected by the resistance and quickly heat up. When the luminous temperature is reached, the tungsten filaments are heated and emit light. High temperature is the principle of tungsten filament luminescence, but high temperature will also cause the conductivity of the glass shell to change. When the tungsten filaments are heated at high temperatures, the glass shell easily becomes a conductor, causing the safety of the bulb to plummet. In addition, tungsten filament bulbs have the disadvantages of serious energy consumption and environmental pollution. In view of this, the inventor has made a new invention. Utility Model Content

DETAILED DESCRIPTION

[0020] The following is combined with Figures 1 to 5 The utility model is described in detail.

[0021] The utility model discloses an LED light bulb with a glass tube, comprising a lamp holder 1, an outer bulb shell 2 and a wick structure 3; the lamp holder 1 is fixedly connected to the outer bulb shell 2; the wick structure 3 comprises a rubber plug 31, a glass tube 32 and an LED lamp bead 33, the rubber plug 31 is tightly assembled with the inner side of the mouth of the outer bulb shell 2, and a mounting hole 311 is further provided in the middle of the rubber plug 31; the glass tube 32 is hollow, and the glass tube 32 is accommodated in the mounting hole 311 and extends into the inner part of the outer bulb shell 2; the LED lamp bead 33 is sealed in the glass tube 32, and the LED lamp bead 33 is electrically connected to a first metal wire 331 and a second metal wire 332, and the other ends of the first metal wire 331 and the second metal wire 332 both extend out of the glass tube 32 and are electrically connected to the lamp holder 1.

[0022] The utility model improves the wick structure 3 of the light bulb, replaces the tungsten filament inside the glass tube 32 with a more energy-saving and environmentally friendly LED lamp bead 33, so that the light bulb does not generate a lot of heat during use, thereby improving the safety of the light bulb during use. At the same time, an outer bulb shell 2 and a lamp holder 1 are sleeved on the outside of the glass tube 32 to further protect the glass tube 32 and effectively extend its service life. Secondly, the mounting hole 311 in the middle of the rubber plug 31 can be used to quickly fix and assemble the glass tube 32, so that the production efficiency of the light bulb is significantly improved.

[0023] Preferably, the bottom of the rubber plug 31 is provided with a flange 312 for use with the mouth of the outer bulb 2. The flange 312 extends from the bottom of the rubber plug 31 to abut against the mouth of the outer bulb 2, effectively preventing the rubber plug 31 from falling directly into the inner part of the outer bulb 2 due to excessive force during automated assembly.

[0024] In the present technical solution, the mounting hole 311 can be a through hole with openings at both ends, but after the glass tube 32 is assembled into the mounting hole 311, the glass tube 32 is easily over-assembled or not assembled in place, resulting in an increase in the defective rate of the bulb. For this reason, the inventors have arranged an end plate 313 at the lower end of the mounting hole 311, and the end plate 313 is provided with a first wire-accommodating hole 314 and a second wire-accommodating hole 315 for the metal wire to pass through. When the glass tube 32 abuts against the end plate 313, it indicates that the glass tube 32 is assembled in place, and at the same time, the end plate 313 can cooperate with the flange 312 to further seal the mouth of the outer bulb 2, thereby improving the waterproof performance of the bulb.

[0025] Preferably, the rubber plug 31 is formed of a soft rubber material, and the first wire-accommodating hole 314 and the second wire-accommodating hole 315 are both blind holes. When the first metal wire 331 and the second metal wire 332 pierce the blind holes, the blind holes can also play a role in fixing the metal wires.

[0026] To further improve the technical solution, a protrusion 316 is provided between the first wire-accommodating hole 314 and the second wire-accommodating hole 315. After the first metal wire 331 and the second metal wire 332 extend out of the wire-accommodating hole, the protrusion 316 is used to separate the first metal wire 331 and the second metal wire 332 to prevent the two from touching and short-circuiting. To simplify the molding process, the protrusion 316 is integrally injection-molded with the end plate 313.

[0027] As another embodiment, a first wire accommodating groove 317 is provided on a side of the first wire accommodating hole 314 away from the second wire accommodating hole 315, and a second wire accommodating groove 318 is provided on a side of the second wire accommodating hole 315 away from the first wire accommodating hole 314. The first metal wire 331 and the second metal wire 332 can pass through the rubber plug 31 along the directions of the wire accommodating grooves on both sides and connect to the lamp holder 1.

[0028] As another example, Figure 2 As shown, the glass tube 32 has a fixing bead 321 integrally formed inside. When the first metal wire 331 and the second metal wire 332 pass through the fixing bead 321, the fixing beads 321 fix the metal wires and the fixing metal wires are supported and separated, so that they will not touch each other easily and cause a short circuit.

[0029] 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.
