Description

Technical Field

[0001] This disclosure relates to the field of lighting, and more particularly to lighting devices that improve the lamp holder. Background Technology

[0002] In existing technology, the lamp holder, which is electrically connected to the external circuit, is relatively small. This means that the lamp driver and switch cannot be located on the lamp holder itself, but rather on the bulb housing above the lamp holder. This results in an unattractive appearance, preventing the lamp from being used for decorative purposes. Furthermore, existing lamps cannot achieve multi-level adjustment of the correlated color temperature (CCT) or wattage of the light source via a switch.

[0003] In order to solve the problems of unsightly appearance and inconvenient use of lamps in the prior art, this disclosure improves the lamp holder. Utility Model Content

[0004] This disclosure aims to solve the problems of unattractive appearance of lamps in the prior art and the inability to adjust lighting parameters in multiple positions via a switch.

[0005] Through the design disclosed herein, the lamp holder and the lighting device using the lamp holder are not only aesthetically pleasing, but also significantly more convenient to use.

[0006] According to one aspect of this disclosure, a lamp holder for use in a lighting device is provided. The lighting device has a bulb connected to the lamp holder and a light source housed inside the bulb. The lamp holder includes a metal threaded portion having an external circuit connection terminal electrically connected to an external circuit and an internal circuit connection terminal opposite to the external circuit connection terminal. A receiving portion includes a lower end, an upper end, and a sidewall between the lower end and the upper end, the lower end, the upper end, and the sidewall defining a receiving space. The lower end is integrally formed with the internal circuit connection terminal of the metal threaded portion, and the upper end is connected to the bulb of the lighting device. The receiving space houses a switch connected to the light source for adjusting the lighting parameters of the light source. Furthermore, the sidewall of the receiving portion is provided with an opening that allows the switch to be controlled from the outside.

[0007] In this way, this disclosure provides a receiving portion at the upper part of the metal threaded portion of the lamp holder to accommodate components such as switches for adjusting the lighting parameters of the light source and drivers for controlling the light emission of the light source, thereby avoiding the arrangement of switches, drivers, and other components on the bulb of the lighting device. This improvement greatly enhances the aesthetics of the lighting device. Furthermore, this disclosure provides an opening in the side wall of the receiving portion, allowing the switch to be controlled directly from the outside of the side wall. This improvement greatly enhances the ease of use of the lighting device.

[0008] According to an exemplary embodiment of this disclosure, the number of switches is the same as the number of types of lighting parameters, and the number of openings is the same as the number of switches.

[0009] According to exemplary embodiments of this disclosure, the types of lighting parameters include correlated color temperature (CCT), wattage, or both.

[0010] In this manner, when the lighting parameter is the correlated color temperature (CCT), only one opening is provided on the side wall of the housing, and a switch inside the housing protrudes from this opening to the outside, allowing the correlated color temperature (CCT) of the light source to be adjusted from the outside. When the lighting parameter is the wattage, a switch inside the housing protrudes from this opening to the outside, allowing the wattage of the light source to be adjusted from the outside, i.e., the brightness of the light source. When the lighting parameter is both the correlated color temperature (CCT) and the wattage, two openings are provided on the side wall of the housing, and two switches inside the housing protrude from the two openings respectively to the outside, allowing the correlated color temperature (CCT) and the wattage of the light source to be adjusted simultaneously from the outside.

[0011] According to an exemplary embodiment of this disclosure, each switch has multiple settings to adjust each type of lighting parameter in multiple settings.

[0012] In this way, the present disclosure can achieve the technical effect of multi-level adjustment of lighting parameters, thereby improving the ease of use and practicality of the lighting device.

[0013] According to an exemplary embodiment of the present disclosure, the interior of the accommodating space further accommodates a driver electrically connected to the light source for controlling the emission of light from the light source.

[0014] In this way, the present disclosure houses the driver in the housing of the lamp holder, avoiding the need to place the driver on the bulb, thereby improving the aesthetic appearance of the lighting device.

[0015] According to an exemplary embodiment of this disclosure, the threads of the metal threaded portion of the lamp holder include E12 threads or E17 threads.

[0016] According to an exemplary embodiment of the present disclosure, an inner insulator is provided inside the sidewall of the receiving portion between the receiving portion and the driver, and the upper edge of the inner insulator is lower than the height of the sidewall.

[0017] In this way, by placing the inner insulator inside the side wall and the driver, the present disclosure avoids short circuits in the driver circuit, reduces circuit failures in the lighting device, and improves the durability and practicality of the lighting device.

[0018] According to an exemplary embodiment of the present disclosure, the exterior of the sidewall of the receiving portion is covered with an outer insulator that surrounds the exterior of the sidewall.

[0019] In this way, the present disclosure improves the overall reliability of the lamp holder by covering the external insulator on the sidewall to avoid openings, ensures stable operation of the lamp holder in various environments by enhancing insulation and withstand voltage performance, and avoids the risk of electric shock when turning on the lamp.

[0020] According to another aspect of this disclosure, a lighting device is provided, comprising a bulb containing glass material and having a light source housed inside the bulb; and the aforementioned lamp holder.

[0021] In this way, this disclosure provides a lighting device that can improve aesthetics and ease of use.

[0022] According to an exemplary embodiment of this disclosure, the light source is a filament-type light source.

[0023] According to an exemplary embodiment of this disclosure, the lighting device is a decorative lamp.

[0024] According to another aspect of this disclosure, a lighting device is provided, comprising a metal lamp holder, an insulating bulb, a driving circuit, and a light source. One end of the metal lamp holder is an external connection terminal connected to an external power source, and the other end is an internal connection terminal connected to the insulating bulb. The interior of the metal lamp holder forms a space for accommodating the driving circuit, and the interior of the insulating bulb forms a space for accommodating the light source. The interior of the metal lamp holder has a switch for controlling the driving circuit and the light source. An opening is further formed on the side wall of the metal lamp holder, allowing the switch to be controlled from the outside.

[0025] According to an exemplary embodiment of the present disclosure, the switch has different settings, each corresponding to controlling at least one of the color temperature, brightness, color, or combinations thereof of the light source.

[0026] According to an exemplary embodiment of the present disclosure, the bulb is made of glass, an internal insulator is further included between the metal lamp holder and the driving circuit, and the metal lamp holder further has an external insulator.

[0027] According to an exemplary embodiment of the present disclosure, the light source is a filament structure, different filaments correspond to different electrical properties, and the metal lamp holder has threads, including E12 threads or E17 threads.

[0028] In the embodiments of this disclosure, a technical solution is provided that improves the lamp head to accommodate components such as the driver and switch, and provides an opening on the outer wall of the lamp head to control the switch from the outside and thus adjust the lighting parameters of the lighting device. This solution at least solves the technical problems of the lamp head being unsightly and having low ease of use when adjusting lighting parameters in the prior art, and achieves the technical effects of improving aesthetics and ease of use.

[0044] Hereinafter, embodiments of the present application will be described in detail with reference to the accompanying drawings to facilitate implementation by those skilled in the art. However, the present application may be implemented in many different forms and should not be construed as limited to the embodiments described herein. In the drawings, portions unrelated to the description of the present application will be omitted for clarity. Similar reference numerals refer to similar elements throughout the description.

[0045] In existing technologies, the size limitations of the lamp holder prevent the driver and switch from being located on the lamp holder itself, instead placing them on the bulb, which affects the appearance and aesthetic design of the lighting fixture. To address this issue, this disclosure proposes an improved lamp holder that houses components such as the driver and switch, which are normally located on the bulb, within the lamp holder. Furthermore, this disclosure includes openings in the lamp holder to allow external control of the switch, driver, and other components, thereby improving the ease of use of the lighting device.

[0046] Figure 1 This is an overall schematic diagram showing a lighting device including an improved lamp holder according to the present disclosure.

[0047] like Figure 1 As shown, the lighting device 1 includes a bulb 11 and a lamp holder 10 connected to the bulb 11. The lighting device 1 can include various types of applications such as indoor lighting, outdoor lighting, industrial lighting, special-purpose lighting, and decorative lighting. In this disclosure, the lighting device 1 is a decorative lamp. The lamp holder 10 is the end of the lamp and is the connection part between the light source and the external power supply. The main function of the lamp holder 10 is to provide an electrical connection for the lamp, ensuring that current can flow safely and effectively through the lamp so that the light source 110 of the lamp emits light. The wiring methods of the lamp holder 10 include riveting, locking, and plugging, which connect the wires to the lamp holder 10 in different ways.

[0048] In this disclosure, the lighting device 1 is a filament-type LED lamp, which features high brightness, high luminous efficacy, high color rendering index, and high reliability. Filament-type LED lamps use semiconductor materials. When current passes through the LED chip, electrons and holes recombine in the semiconductor material, directly generating photons and emitting light. This process is called electroluminescence, which directly converts electrical energy into light energy with almost no heat generation, thus resulting in higher efficiency.

[0049] The bulb 11, located outside the filament-type LED lamp, is the main body of the lamp. Inside the bulb 11 is housed the light source 110, which is the LED filament. The bulb 11 is made of heat-resistant glass and its structure can be spherical or other shapes to suit different lighting needs and aesthetic designs. Air is evacuated from the bulb 11 to create a vacuum, reducing filament oxidation, or an inert gas (such as argon) can be added to reduce tungsten filament sublimation. The bulb 11 protects the internal LED filament from external physical damage and also prevents oxidation or other chemical reactions caused by oxygen and moisture in the external environment. The bulb material has good light transmittance, ensuring that light can effectively penetrate and diffuse, providing uniform lighting. The bulb 11 participates in the lamp's heat dissipation process, helping to dissipate the heat generated during lamp operation through convection and radiation, ensuring the lamp's normal operating temperature. The shape and color design of the bulb 11 enhances the lamp's aesthetics, allowing it to adapt to different decorative styles and lighting needs.

[0050] In this disclosure, the lamp holder 10 also includes a metal threaded portion 101 and a receiving portion 102. The metal threaded portion 101 has an external circuit connection terminal electrically connected to an external circuit, and an internal circuit connection terminal opposite to the external circuit connection terminal. Specifically, the metal thread in the external circuit connection terminal is connected to the neutral wire of the external circuit, and the central protrusion at the bottom is connected to the live wire of the external circuit, thereby ensuring that the current from the external circuit causes the lamp to light up.

[0051] In other embodiments, the lamp holder 10 may also be a bayonet lamp holder, and is not limited to a threaded lamp holder.

[0052] The receiving part 102 includes a lower end, an upper end, and a side wall between the lower end and the upper end. The lower end, the upper end, and the side wall define a receiving space. The lower end is integrally formed with the internal circuit connection end of the metal threaded part. The upper end is connected to the bulb 11 of the lighting device 1. The receiving space contains a switch 1020 connected to the light source to adjust the lighting parameters of the light source.

[0053] The side wall of the receiving part 102 is also provided with an opening 1021, which allows the switch 1020 to be controlled from the outside.

[0054] Switch 1020 is a mechanical dimming switch, such as a rotary type (adjusted by rotating a knob) or a toggle type (adjusted by moving a dial). Switch 1020 can adjust the current through the lamp by changing the resistance value in the circuit or by sending different commands to a chip in the drive circuit to adjust other electrical parameters (such as duty cycle), thereby changing the lamp's brightness, i.e., adjusting the lamp's wattage. Wattage is a unit of measurement for power, and its applications are very widespread; it can be used to measure the power consumption of various devices.

[0055] Switch 1020 can be used in lamps containing multiple groups of LEDs, such as a group of LEDs with a color temperature of 2700K, a group of LEDs with a color temperature of 4000K, and a group of LEDs with a color temperature of 5000K. The switch allows switching between different color temperatures by toggling between different settings, thus adjusting the overall color temperature of the lamp.

[0056] Correlated color temperature (CCT) is an important parameter describing the color characteristics of a light source. It is determined by comparing the color of light emitted by the light source with the color of light emitted by a black body (such as platinum) at a certain temperature. The temperature of the black body at that temperature is then expressed as the color temperature of the light source, using Kelvin (K). The unit of CCT is absolute temperature (Kelvin, K). It does not directly measure the brightness of the light, but rather describes the temperature of the black body when its color of light matches the color of light emitted by the light source. The CCT range typically extends from approximately 2700K (warm tone) to approximately 6500K (cool tone). At around 3000K, the light has a yellowish tint, giving a warm feeling; at color temperatures above 5000K, the light has a bluish tint, giving a refreshing or cool feeling. Different color temperatures can affect people's emotions and behaviors, making the selection of an appropriate color temperature crucial in lighting design. In practical applications, the choice of CCT is critical for creating a specific atmosphere or meeting specific needs. For example, indoor lighting may require a lower color temperature to create a warm atmosphere, while offices or hospitals may require a higher color temperature to provide a clear visual environment. Furthermore, the choice of CCT is crucial for photography and filmmaking to ensure the color quality of photographs or films.

[0057] In one example, switch 1020 protrudes from opening 1021 to the outside, and operators can directly control switch 1020 from the outside (e.g., by toggle or rotation) and thus adjust the correlated color temperature (CCT) or wattage through switch 1020.

[0058] In this disclosure, the number of switches is the same as the number of types of lighting parameters, and the number of openings is the same as the number of switches. The types of lighting parameters include correlated color temperature (CCT), wattage, or both.

[0059] When the lighting parameter is correlated color temperature (CCT), only one opening is provided on the side wall of the receiving part 102. A switch inside the receiving part 102 protrudes from this opening 1021 to the outside, allowing the correlated color temperature (CCT) of the light source 110 to be adjusted from the outside. When the lighting parameter is wattage, a switch inside the receiving part 102 protrudes from this opening 1021 to the outside, allowing the wattage of the light source 110 to be adjusted from the outside, i.e., the brightness of the light source. When the lighting parameter is both correlated color temperature (CCT) and wattage, two openings 1021 are provided on the side wall of the receiving part 102. Two switches inside the receiving part 102 protrude from the two openings 1021 respectively to the outside, allowing the correlated color temperature (CCT) and wattage of the light source to be adjusted simultaneously from the outside.

[0060] Each switch has multiple settings to adjust each type of lighting parameter (brightness, color temperature, color, etc.). For example, the correlated color temperature (CCT) can be set to 3 or 5 settings: 2700K, 4000K, and 5000K. The multiple settings of each switch can be configured according to actual needs.

[0061] Figure 2 This is an exploded view showing the lamp holder according to this disclosure.

[0062] like Figure 2 As shown, the interior of the housing also houses a driver 1024 that is electrically connected to the light source 110 to control the light emission of the light source. For example, the driver 1024 is connected to the power supply 110 via a wire.

[0063] An inner insulator 1023 covers the interior of the sidewall of the receiving portion 102 between it and the driver 1024, with the upper edge of the inner insulator being lower than the height of the sidewall. In this case, the driver 1024 is stacked inside the inner insulator 1023. The switch 1020 is also stacked inside the inner insulator 1023.

[0064] The specific height difference between the inner insulator 1023 and the sidewall simplifies the connection process of the lamp holder 10. For example, by using injection molding to embed the receiving part into the sidewall, the connection is more secure, reducing the complexity of the connection process. The design that the upper edge of the inner insulator 1023 is lower than the sidewall helps to improve the overall structural stability of the lamp holder 10. This design provides better support and fixation, reducing structural deformation caused by external forces or thermal expansion. The design of the inner insulator 1023 may also make the installation and maintenance of the lamp holder 10 easier. For example, the inner insulator 1023 can serve as a guide or positioning structure to help correctly install the driver and other components. The design of the inner insulator 1023 reduces direct contact between electrical components, thereby reducing the risk of short circuits or electrical fires and improving overall electrical safety.

[0065] The outer sidewall of the receiving part 102 is covered with an outer insulator 1022 that surrounds the outer sidewall except for the opening.

[0066] Both the inner insulator 1023 and the outer insulator 1022 are provided with openings 1021 corresponding to the switch 1020 housed inside.

[0067] The connection between the upper end of the receiving portion 102 of the lamp holder 10 and the bulb 11 is a crucial part of the lamp structure. It not only relates to the electrical connection of the lamp but also to its sealing and aesthetics. The upper end of the bulb 11 and the receiving portion 102 can be bonded together, for example, by using lamp holder putty to fix the bulb 11 and the lamp holder 10 together.

[0068] In the embodiments of this disclosure, a technical solution is provided to improve the lamp head to accommodate components such as drivers and switches, and to adjust the lighting parameters of the lighting device by providing an opening on the outer wall of the lamp head to control the switch from the outside. This solution at least solves the technical problems of the lamp head in the prior art being unsightly and having low ease of use when adjusting lighting parameters, thereby achieving the technical effects of improving aesthetics and ease of use.

[0069] In the above embodiments of this disclosure, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0070] In the several embodiments provided in this disclosure, it should be understood that the disclosed technical content can be implemented in other ways.

[0071] The above description is only a preferred embodiment of this disclosure. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principles of this disclosure, and these improvements and modifications should also be considered within the scope of protection of this disclosure.
