[0051] Furthermore, the lamp holder 400 is connected to the control board 300, and the lamp holder 400 is used to be connected to an external power source, thereby connecting the control board 300 to the external power source.

[0052] The core column 500 is arranged in the accommodating cavity, wherein the core column 500 is an insulating structure. In this embodiment, the core column 500 is a transparent core column 500, that is, the core column 500 is a transparent glass column to enhance the aesthetics of the core column 500 and the aesthetics of the lamp and avoid affecting the luminous effect of the lamp.

[0053] In addition, the stem 500 is connected to the bulb 200 to improve the stability of the stem 500 in the receiving cavity. Figure 1 and Figure 4 In this embodiment, the stem 500 and the bulb shell 200 are formed by welding, and the accommodating cavity inside the bulb shell 200 is evacuated to form a hair bubble, and the hair bubble is fixed to the lamp cup 100 or the lamp holder 400 by gluing or snapping. It should be noted that the hair bubble mentioned here refers to a structure in which the bulb 200 and the stem 500 are connected and formed.

[0054] Among them, the end of the stem 500 away from the lamp holder 400 is provided with a plurality of staggered first guide wires 610 and second guide wires 620 connected to the control board 300. It can be understood that the number of the first guide wires 610 and the number of the second guide wires 620 can be two or more numbers of any value, which can be specifically set according to actual conditions, and the number of the first guide wires 610 is equal to the number of the second guide wires 620.

[0057] One end of the filament 800 is connected to the first guide wire 610 and / or the second guide wire 620 , and the other end of the filament 800 is connected to the third guide wire 710 and / or the fourth guide wire 720 , thereby electrically connecting the filament 800 to the control board 300 .

[0058] It should be noted that the filament 800 described in this embodiment is a dual-color temperature filament or a multi-color temperature filament, and the dual-color temperature filament can be switched to white light or yellow light as needed to meet the different needs of users. By staggering the first guide wire 610 and the second guide wire 620, and staggering the third guide wire 710 and the fourth guide wire 720, the situation of adjacent filaments 800 contacting and short-circuiting is avoided, thereby ensuring the safety of the lamp during use, so as to facilitate the connection of the dual-color temperature filament or the multi-color temperature filament, thereby improving the diversity of the light-emitting form of the lamp, and enhancing the user experience.

[0060] It should be noted that, in this embodiment, the control board 300 is a PCB (Printed Circuit Board), that is, a printed circuit board or a printed circuit board.

[0061] like Figure 3 and Figure 6 As shown, in some embodiments of the present invention, the filament 800 includes at least a first color temperature filament 810 and a second color temperature filament 820 .

[0062] It is understandable that the filament 800 may be a dual-color temperature filament or a multi-color temperature filament.

[0063] In this embodiment, the filament 800 is taken as a dual-color color temperature filament as an example for specific description as follows, that is, the filament 800 includes a first color temperature filament 810 and a second color temperature filament 820 .

[0064] The first color temperature filament 810 has a first pin 811 and a second pin 812 spaced apart from each other, and the first pin 811 is connected to the first guide wire 610, and the second pin 812 is connected to the third guide wire 710, so that the first color temperature filament 810 is connected to the control board 300, so that the start or shut down of the first color temperature filament 810 can be controlled by the control board 300.

[0065] In addition, the second color temperature filament 820 has a third pin 821 and a fourth pin 822 spaced apart from each other, and the third pin 821 is connected to the second guide wire 620, and the fourth pin 822 is connected to the fourth guide wire 720, so that the second color temperature filament 820 is connected to the control board 300, so that the start or shut down of the second color temperature filament 820 can be controlled by the control board 300.

[0066] It can be understood that by connecting the first color temperature filament 810 and the second color temperature filament 820 to the control board 300 respectively, that is, the first color temperature filament 810 and the second color temperature filament 820 can be controlled separately through the control board 300, that is, the user can control the start or shut down of the first color temperature filament 810 and the second color temperature filament 820 according to actual needs to meet different needs of users.

[0067] In this embodiment, the color temperature of the first color temperature filament 810 is less than or equal to 3000 K. It is understandable that the color temperature of the first color temperature filament 810 can be any value less than or equal to 3000 K, and can be specifically set according to actual conditions. Specifically, in this embodiment, the color temperature of the first color temperature filament 810 is 2200 K.

[0068] In addition, the color temperature of the second color temperature filament 820 is greater than or equal to 4000 K. It is understandable that the color temperature of the second color temperature filament 820 can be any value greater than or equal to 4000 K, and can be specifically set according to actual conditions. Specifically, in this embodiment, the color temperature of the second color temperature filament 820 is 6500 K.

[0069] It should be noted that color temperature is expressed in absolute temperature K, which describes the color characteristics of the light source. When a standard black body is heated, its color will gradually change from deep red to light red, orange-yellow, and finally to white and blue as the temperature rises. The unit of color temperature is K (Kelvin).

[0070] A color temperature of 2200K is considered warm white, and this color of light is close to the color of the sun, giving people a warm feeling. In the selection of lamps, a color temperature of 2200K is often used in occasions where a warm and comfortable environment needs to be created, such as home lighting. The choice of color temperature not only affects the color of light, but also the atmosphere of the space and people's psychological feelings. For example, a lower color temperature (such as below 3000K) can provide a warm and soft atmosphere, while a higher color temperature (such as above 5000K) may give people a cold feeling. Therefore, when choosing lamps, color temperature is an important consideration, and it can be adjusted according to different usage scenarios and needs to achieve the best light environment effect.

[0071] In some embodiments of the present invention, a plurality of filaments 800 are arranged at equal intervals in the circumferential direction of the stem 500 to improve the uniformity of light emission of the lamp.

[0072] In some embodiments of the present invention, the lamp includes a battery, the battery is disposed in the cavity 110 , and the battery is connected to the control board 300 to supply power to the control board 300 through the battery.

[0073] like Figure 2 and Figure 3 As shown, in some embodiments of the utility model, the core column 500 includes a core column 510 and a seat body 520, one end of the first guide wire 610 and the second guide wire 620 are passed through the core column 510 and connected to the control board 300, and one end of the third guide wire 710 and the fourth guide wire 720 are passed through the seat body 520 and connected to the control board 300, so that the filament 800 is electrically connected to the control board 300 through the first guide wire 610, the second guide wire 620, the third guide wire 710 and the fourth guide wire 720, so as to control the filament 800 to start or stop through the control board 300.

[0074] It can be understood that one end of the first filament 800 and the second filament 800 is passed through the core column 510 and connected to the control board 300, and one end of the third guide wire 710 and the fourth guide wire 720 is passed through the base body 520 and connected to the control board 300, thereby connecting the first color temperature filament 810 and the second color temperature filament 820 to the control board 300 respectively.

[0075] like Figure 2 and Figure 5 As shown, in some embodiments of the present invention, the axis of the stem 500 coincides with the axis of the bulb 200 to improve the uniformity of the distribution of the filament 800 in the accommodating cavity and improve the uniformity of the light emission of the lamp.

[0076] like Figure 3 and Figure 6As shown, in some embodiments of the present invention, the number of the first guide wire 610, the second guide wire 620, the third guide wire 710 and the fourth guide wire 720 is equal, and is greater than or equal to the number of the filaments 800. It is understandable that the user can adjust the number of filaments 800 according to actual conditions. In addition, the user can also adjust the number of filaments 800 connected to the power supply according to actual conditions to meet different needs of the user.

[0077] like Figure 1 As shown, in some embodiments of the present invention, the lamp holder 400 includes a housing 410 , an insulating portion 420 and a conductive portion 430 .

[0078] Specifically, a portion of the shell 410 is sleeved on one end of the lamp cup 100 away from the bulb 200, and another portion of the shell 410 is sleeved on the insulating portion 420. The insulating portion 420 is provided with a mounting hole, and the conductive portion 430 is disposed in the mounting hole and sealed on the mounting hole to form a sealed connection structure. The insulating portion 420 abuts against the lamp cup 100 at one end facing the bulb 200.

[0079] It should be noted that the housing 100 is a conductive shell, and the housing 100 and the conductive portion 430 are electrically connected to the control board 300 respectively, that is, the control board 300 can be electrically connected to an external power source through the lamp holder 400.

[0080] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limiting, and thus other examples of the exemplary embodiments may have different values.

[0081] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0082] The above-mentioned embodiments only express several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
