[0028] Reference Figure 1 and Figure 2 The light bulb of the first embodiment of the utility model comprises: a lamp housing 100, which is a glass lamp housing 100; a light-emitting component, which is arranged in the lamp housing 100, and comprises a first light-emitting component 210 and a second light-emitting component 220, wherein the first light-emitting component 210 and the second light-emitting component 220 are connected in parallel, the first light-emitting component 210 comprises a first positive terminal and a first negative terminal, the second light-emitting component 220 comprises a second positive terminal and a second negative terminal, the first positive terminal is electrically connected to the second negative terminal, and the first negative terminal is electrically connected to the second positive terminal; a wire 300, part of which is arranged in the lamp housing 100 and sealed with the lamp housing 100, the first light-emitting component 210 and the second light-emitting component 220 are both fixed on the wire 300, and the first light-emitting component 210 and the second light-emitting component 220 are both electrically connected to the wire 300. The first light-emitting component 210 and the second light-emitting component 220 are both SMD LEDs. It should be noted that in this embodiment, at least two wires 300 are arranged, and the two wires 300 are respectively connected to the power supply.

[0029] Christmas bulbs are mostly used outdoors. When it rains, rainwater will stick to the wire 300 of the bulb. When the bulb is powered on, the wire 300 and water will undergo an oxidation reaction to electrolyze water and consume the wire 300 at the same time. The first positive terminal is electrically connected to the second negative terminal, and the first negative terminal is electrically connected to the second positive terminal. When an AC power supply is connected, the first light-emitting element 210 and the second light-emitting element 220 will light up at the same time. The direction of the current on the wire 300 is constantly changing, so that the direction of the flow of electrons on the wire 300 is constantly changing. Oxidation and reduction reactions are constantly taking place on the wire 300, and the oxidation and reduction reactions are carried out alternately, so as to avoid a single current direction on the wire 300 after power is turned on, so that only one of the two wires 300 undergoes an oxidation reaction, thereby reducing the loss of the wire 300 caused by long-term oxidation reaction, avoiding the wire 300 from breaking, and increasing the service life of the bulb.

[0030] The outer surfaces of the first light emitting member and the second light emitting member are both wrapped with protective glue, the connection between the first light emitting member and the wire is wrapped by the protective glue, and the connection between the second light emitting member and the wire is wrapped by the protective glue.

[0031] It can be understood that the wire 300 includes an internal wire 310 and an external wire 320, the internal wire 310 and the external wire 320 are electrically connected, the internal wire 310 is arranged in the lamp housing 100 and sealed with the lamp housing 100, and the external wire 320 is arranged outside the lamp housing 100. The internal wire 310 is arranged in the lamp housing 100, the internal connection is connected in parallel with the first light-emitting element 210 and the second light-emitting element 220, and the external wire 320 is arranged outside the lamp housing 100 for connecting to an external power source.

[0032] It is understandable that the lamp housing 100 is in a columnar shape. The lamp housing 100 initially has openings at both ends. After the first light-emitting member 210 and the second light-emitting member 220 are fixed on the wire 300, the first light-emitting member 210 and the second light-emitting member 220 are inserted into the lamp housing 100, and the wire 300 inserted into the lamp housing 100 is formed as an inner wire 310, and the wire 300 remaining outside the lamp housing 100 is formed as an outer wire 320. The glass is softened by heating the glass to 600 degrees Celsius, and then the two ends of the lamp housing 100 are sealed. Alternatively, the insertion end of the wire 300 and the lamp housing 100 is sealed first, and then the other end is sealed. Compared with a conventional light bulb in which the wick is separately inserted into the lamp housing 100, after the lamp housing 100 made of glass is melted and sealed, the lamp housing 100 and the wire 300 are formed as one piece. The light bulb can prevent dust and water from entering the lamp housing 100, and has better sealing. The light bulb can prevent dust and water from entering the light-emitting part, and has better sealing. Therefore, the light bulb can withstand more severe usage environments such as rainy days, and has a wider application.

[0033] Specifically, the inner wire 310 includes a first inner wire 311 and a second inner wire 312, and the first inner wire 311, the first light-emitting element 210, the second inner wire 312 and the second light-emitting element 220 are electrically connected in sequence. The first inner wire 311 is electrically connected to the external wire 320, and the first inner wire 311 is electrically conductive by contacting with the external wire 320. In addition, the first inner wire 311 and the external wire 320 are integrally formed, which can improve the strength of the wire 300. In some embodiments, the first inner wire 311, the second inner wire 312 and the external wire 320 are integrally formed, and the first light-emitting element 210 and the first inner wire 311 are connected, and the second light-emitting element 220 and the second inner wire 312 are connected by welding. The first inner wire 311, the second inner wire 312 and the external wire 320 are integrally formed, which can further improve the structural strength of the wire 300.

[0034] It is understandable that the first inner line 311 is bent so that the first light-emitting element 210 emits light obliquely upward, and the light of the first light-emitting element 210 is emitted more upward and horizontally, reducing the light emitted downward, thereby improving the brightness of the first light-emitting element 210.

[0035] Similarly, the second inner line 312 is bent so that the second light emitting element 220 emits light obliquely upward, reducing the light emitted downward, and emitting more light in the horizontal direction and upward, thereby enhancing the brightness of the second light emitting element 220 .

[0036] It is understandable that the wire 300 is made of Dumet wire. Dumet wire is one of the basic metal wires 300, and is mainly used for vacuum sealing between glass and metal. Dumet wire is composed of a copper-nickel-iron core, a copper layer and a dense oxide layer, and is mainly used in the lighting manufacturing industry and the diode manufacturing industry. Through the Dumet wire and the lamp housing 100, the light-emitting component is arranged in the lamp housing 100. The lamp housing 100 is made of glass, and the light transmission effect is better, and there will be no plastic aging problem.

[0037] It is understandable that the outer surfaces of the first light-emitting member 210 and the second light-emitting member 220 are both wrapped with protective glue, which protects the first light-emitting member 210 and the second light-emitting member 220 from damage by impact and plays a waterproof role. The outer surfaces of the first light-emitting member 210 and the second light-emitting member 220 are both wrapped with protective glue, and the connection between the first light-emitting member 210 and the wire 300 is wrapped with protective glue, and the connection between the second light-emitting member 220 and the wire 300 is wrapped with protective glue, so as to prevent the wire 300 from being disconnected from the first light-emitting member 210 and the second light-emitting member 220 due to external force.

[0038] The decorative light string of the second embodiment of the utility model includes a light bulb according to the first embodiment of the utility model. The first positive terminal is electrically connected to the second negative terminal, and the first negative terminal is electrically connected to the second positive terminal. When an AC power source is connected, the first light-emitting element 210 and the second light-emitting element 220 will light up at the same time, and the current direction on the wire 300 is constantly changing, so that the direction of the flow of electrons on the wire 300 is constantly changing, and oxidation reaction and reduction reaction are constantly carried out on the wire 300, and the oxidation reaction and reduction reaction are carried out crosswise, so as to avoid the current direction on the wire 300 being single after power is turned on, so that only one of the two wires 300 undergoes oxidation reaction, thereby reducing the loss of the wire 300 caused by long-term oxidation reaction, avoiding the wire 300 from breaking, and improving the service life of the light bulb.

[0039] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
