LED candle lamps are commonly used in the market. LED candles are widely used in many scenarios such as home decoration, religious ceremonies, and creating a romantic atmosphere due to their safety, environmental protection and long-lasting properties. Traditional LED candles, to a certain extent, meet people's basic needs for candle lighting and atmosphere creation.

[0003] Existing LED candles consist of a shell, a lamp tube, and a battery. The shell of the LED candle is used to mimic the appearance of a real candle and to hold the internal lamp tube and battery. The lamp tube uses LED beads to emit stable light, and the battery provides power to the LED candle's lamp tube to ensure that the candle can light up normally.

[0004] In the existing technology, a considerable number of LED candles have a fixed and non-adjustable brightness. This non-adjustable brightness design makes it difficult to adapt flexibly to different usage scenarios. For example, in some romantic dinner scenarios that require creating a warm and soft atmosphere, LED candles with fixed brightness will be too bright and destroy the necessary tranquility. Therefore, adjustable brightness LED candles are proposed to solve the above problems. Utility Model Content

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of an adjustable brightness LED candle, including a lamp housing 1. The lamp housing 1 serves as the outer shell of the entire adjustable brightness LED candle, providing protection and connection. An illumination mechanism 2 is disposed inside the lamp housing 1. Two slots 101 are formed at the bottom of the lamp housing 1 for assembly and restraint. A rotating mechanism 3 is disposed outside the two slots 101. The illumination mechanism 2 includes a connecting cover 201 for connecting the lamp housing 1. The connecting cover 201 is internally threaded to the top of the lamp housing 1. A control end 202 is fixedly connected to the inner wall of the connecting cover 201. The control end 202 serves as... The control core of the entire lighting system receives power from the power components. Two power components for generating electricity are fixedly connected to the bottom of the control terminal 202. Each power component has a copper terminal 204 fixedly connected to its bottom. The copper terminal 204 acts as a conductor for power transmission, transferring the power generated by the power components to the potentiometer 206. Copper has good electrical and thermal conductivity, enabling efficient power transmission, and also possesses a certain degree of corrosion resistance, ensuring the stability of power transmission. The potentiometer 206 is slidably connected to the outside of the copper terminal 204. The potentiometer 206 is used to adjust the brightness of the lighting components. By changing the resistance value, the control... The current output from the control terminal 202 to the LED lamp 207 is adjusted to control the brightness of the LED lamp 207. A lighting component is fixedly connected to the output of the control terminal 202. A candle wax decoration 209 is fixedly connected to the outside of the connecting cover 201, serving a decorative purpose to make the adjustable brightness LED candle more closely resemble the appearance of a real candle. The power component includes two battery slots 203, which are used to connect to a power source 205. The tops of the two battery slots 203 are fixedly connected to the bottom of the control terminal 202, and the power source 205 is snapped into the inside of each battery slot 203. 205 provides stable power to LED lamp 207. The bottom of battery compartment 203 is fixedly connected to the outside of copper end 204. The lighting component includes LED lamp 207. LED lamp 207 uses high-brightness, low-power LED chips and has advantages such as high luminous efficiency and long life. The receiving end of LED lamp 207 is fixedly connected to the output end of control end 202. Candle sleeve 208 is fixedly connected to the outside of LED lamp 207. Candle sleeve 208 is made of translucent plastic material and has good light transmission and optical performance, which makes the light emitted by LED lamp 207 softer and simulates the candlelight effect.

[0033] Reference Figure 1 , Figure 2 and Figure 5The rotating mechanism 3 includes two limiting blocks 301, which are externally engaged with the inside of the slot 101. The limiting blocks 301 are used to assemble and limit the lamp housing 1. A fixed frame 302 is fixedly connected to the opposite side of the two limiting blocks 301. The fixed frame 302 is used for fixing and supporting, and is made of plastic with good insulation to ensure electrical safety. A base 304 is rotatably connected to the outside of the fixed frame 302. The base 304 provides support and stability for the entire adjustable brightness LED candle. An anti-slip pad 306 is fixedly connected to the bottom of the base 304. The anti-slip pad 306 increases the friction between the base 304 and the table or other supporting surfaces, preventing the adjustable brightness LED candle from sliding during use and improving stability. A sliding shaft 303 is provided at the bottom of the fixed frame 302. The sliding shaft 303 cooperates with the locking teeth 305 to achieve positioning and resistance when the fixed frame 302 rotates. Force feedback is provided by multiple locking teeth 305 fixedly connected to the inner wall of the base 304. The locking teeth 305 cooperate with the sliding shaft 303 to achieve positioning and resistance feedback when the fixed frame 302 rotates, so that the brightness adjustment has a clear sense of level. The adjacent sides of the multiple locking teeth 305 are slidably connected to the inside of the sliding shaft 303. The sliding shaft 303 is fixed to the inside of the base 304, so that when the fixed frame 302 rotates, the sliding shaft 303 is locked to the outside of the locking teeth 305. The bottom of the potentiometer 206 is fixedly connected to the inside of the base 304, and the outside of the potentiometer 206 is rotatably connected to the inside of the fixed frame 302. By engaging the slot 101 with the outside of the limiting block 301 inside the fixed frame 302, the copper end 204 contacts the potentiometer 206. By rotating the fixed frame 302, the copper end 204 slides on the top of the potentiometer 206, so that the control power component provides power.

[0034] Working principle: Before use, the power source 205 is inserted into the battery compartment 203, which transmits power to the control terminal 202. The connecting cover 201 is then connected to the top of the lamp housing 1 by threads, fixing the control terminal 202 and the power component inside the lamp housing 1, which serves as a seal and protection. Power is transmitted outward through the copper end 204 at the bottom of the battery compartment 203. The copper end 204 is slidably connected to the potentiometer 206. By changing the position of the copper end 204 on the potentiometer 206, the resistance value is changed. When the resistance value of the potentiometer 206 changes, the control terminal 202 will adjust the current output to the lighting component according to this change. According to the different currents output by the control terminal 202, the LED light 207 emits light of different brightness. When the light emitted by the LED light 207 is scattered and filtered through the candle holder 208, it simulates the candlelight effect of a candle.

[0035] The slot 101 at the bottom of the lamp housing 1 engages with the limiting block 301 on the fixed frame 302, thus making the lamp housing 1 and the fixed frame 302 a single unit that can rotate together. The fixed frame 302 is externally rotatably connected to the base 304. When the user rotates the fixed frame 302, the copper end 204 fixed inside the lamp housing 1 rotates with the fixed frame 302 and slides on top of the potentiometer 206. The sliding of the copper end 204 on the potentiometer 206 changes the resistance value of the potentiometer 206, thereby adjusting the brightness. When the fixed frame 302 rotates, the sliding shaft 303 slides outside the locking teeth 305. The shape and spacing design of the locking teeth 305 make the sliding shaft 303 generate a certain resistance and positioning feel during the sliding process. The user can feel a clear change in brightness when rotating the fixed frame 302, which facilitates brightness adjustment. The anti-slip pad 306 at the bottom of the base 304 prevents the candle from sliding during use.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
