Description

Technical Field

[0001] The present invention relates to the technical field of lighting-related technologies, and in particular to an LED candlelight lamp structure. Background Art

[0002] Before the invention of the electric light, candles were one of the most widely used lighting fixtures. After electric lighting became widespread, candles were only used on special occasions. With the improvement of living standards and the spread of cultural and leisure activities, candles have gradually revived as a decorative object, becoming widely used during traditional festivals. Traditional candles can easily cause air pollution and pose a fire hazard when burned. For this reason, candlelight lamps are now used in most situations instead of traditional candles. These candlelight lamps are made from incandescent bulbs shaped like candles. However, due to their high power consumption, incandescent lamps do not meet energy conservation requirements. Technological advancements have led to the invention of LEDs. LEDs, which replace incandescent lamps, are smaller and more similar to traditional candles, consuming less power and being more environmentally friendly. However, because LED chips generate a lot of heat when emitting light, the lifespan of candlelight lamps is affected by poor heat dissipation. Chinese Invention Patent Publication No. CN102563432A, published on July 11, 2012, discloses an LED lighting lamp with a spherical bulb in the shape of a flower bud. The invention comprises a light bulb comprising a lamp housing with a hemispherical lower portion and a hemispherical translucent lampshade connected to the lower end of the lamp housing, a light source integrated module located within the light bulb, and a driver circuit board. The lighting lamp also comprises an inverted polygonal pyramidal lampshade inner shell located within the light bulb and having an air vent on its lower end surface. The upper end of the lampshade inner shell is connected to the lower end of the lamp housing, and the lower end abuts against the inner surface of the translucent lampshade, so that the conical surfaces of the lampshade inner shell are distributed within the translucent lampshade, and each conical surface of the lampshade inner shell is provided with a light source hole. The lower portion of the translucent lampshade is provided with an air inlet coaxial with and identical in shape to the air vent on the lampshade inner shell, so that a continuous pneumatic convection channel is formed between the air inlet and the air outlet on the lamp housing. The number of light source integrated modules is equal to the number of conical surfaces of the lampshade inner shell. Each light source integrated module includes a printed circuit board, an LED light source connected to the front and rear surfaces of the printed circuit board, and a plurality of heat sinks. Each light source integrated module is mounted on the conical surface of the lampshade inner shell with the LED light source embedded in the light source hole of the lampshade inner shell and the heat sinks located on the inner side of the conical surface. The direction of the heat dissipation groove formed between the heat sinks on each light source integrated module is aligned with the direction of the aerodynamic convection channel. This technical solution improves the efficiency of conductive heat dissipation through dynamic aerodynamic convection heat dissipation, thereby increasing the service life of the LED. When the LED lamp is in use, hot air is discharged from the openings of the translucent lampshade, making it difficult for dust to fall into the lampshade through the openings. However, when the LED lamp is not in use, hot air is not discharged from the openings of the translucent lampshade, allowing dust to easily fall into the lampshade through the openings. Dust entering the lampshade and adhering to the LED light source not only reduces the brightness of the light but also corrodes the light source, shortening the service life of the LED lamp. Summary of the Invention

[0003] In order to overcome the defect of the prior art LED candlelight lamp that is difficult to dissipate heat and affects the service life, the present invention provides an LED candlelight lamp structure that can quickly dissipate heat and prevent dust from entering the lampshade to extend the service life.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: an LED candlelight lamp structure, which includes a base body, a connecting ring, a wick cover, a wick column fixed to the base body, and an LED wick connected to the wick column. The connecting ring is a tubular structure made of soft material. The connecting ring is provided with a plurality of air holes penetrating the side wall. One end of the connecting ring is fixed to the wick cover, and the other end of the connecting ring is fixed to the base body. The wick cover and the base body are connected to form a cavity structure. The LED wick is located in the cavity. When the LED wick loses power, the wick cover and the base body are sealed and connected. When the LED wick is powered on, it emits light and generates heat, and the air holes connect the inside and outside of the cavity.

[0005] When the LED wick loses power, it neither emits light nor generates heat. The wick cover is sealed to the base under the action of gravity. The LED wick falls into the sealed cavity where the wick cover and the base are connected, preventing dust from invading, keeping the LED wick clean, and providing a good luminous effect, thereby extending the service life of the LED candlelight. When the LED wick receives power, it emits light to form candlelight. At the same time, the LED wick generates heat, and the air in the sealed cavity where the wick cover and the base are connected is heated and expanded. The wick cover is lifted up by the hot air, and the wick cover and the base are disconnected at the connection. The gas inside and outside the cavity is exchanged through the air holes connecting the inside and outside of the cavity, cooling the gas inside the cavity. The LED wick will not be damaged by heat, thereby improving the luminous efficiency of the LED wick and extending the service life of the LED candlelight.

[0006] Preferably, the base body includes an electrode connection device at the bottom and a base connection sleeve at the top. The electrode connection device is a standard screw-on or plug-in lamp holder. The base connection sleeve is a truncated cone tubular shape. The large-diameter truncated cone surface is the open end of the base connection sleeve. The open end face of the base connection sleeve is perpendicular to the side wall of the base connection sleeve. The standard bulb connector is convenient for connection with a standard lamp holder, has good versatility, and a wide range of uses. The wick cover and the base connection sleeve fit together through the side of the truncated cone body, and have good sealing performance. After the wick cover is separated from the base, it is convenient to automatically connect by relying on the deadweight of the wick cover. The open end face of the base connection sleeve is perpendicular to the side wall of the base connection sleeve, so that the air hole and the open end face of the base connection sleeve are convenient to fit tightly, effectively preventing dust from intruding.

[0007] Preferably, the lower portion of the wick cover is in the shape of a truncated cone, with the small-diameter truncated cone being the open end of the wick cover. The open end face of the wick cover is perpendicular to the central axis of the truncated cone of the wick cover. The outer surface of the lower portion of the wick cover is provided with a guide surface, which forms an acute angle with the open end face of the wick cover. The closer the outer surface of the lower portion of the wick cover is to the end face, the smaller the diameter. When the wick cover falls, the wick cover can quickly return to the connection state with the seat connecting sleeve, making it easier to connect the wick cover and the seat connecting sleeve. When the wick cover rises, the guide surface guides the airflow to communicate with the air hole, making the airflow exchange smoother and improving the cooling effect on the LED wick.

[0008] Preferably, the wick cover is provided with a retaining ring, which protrudes from the outer surface of the lower portion of the wick cover and is located below the fixing portion between the connecting ring and the wick cover. The end surface of the open end of the base connecting sleeve is provided with a connecting groove, and the lower portion of the wick cover is sleeved with the base connecting sleeve, with the retaining ring matching the connecting groove. The outer surface of the lower portion of the wick cover is sleeved with the inner surface of the base connecting sleeve to form a sealed connection, and the retaining ring is embedded in the connecting groove for connection, forming a double sealing structure with good sealing effect.

[0009] Preferably, the open end of the seat connecting sleeve is provided with an outer ring, the outer ring protrudes from the outer surface of the side wall of the seat connecting sleeve, the wick cover is sealed to the seat body, and the air hole is fitted with the end face of the opening of the seat connecting sleeve; when the wick cover is detached from the seat body, the inner surface of the side wall of the connecting ring is fitted with the outer ring. When the wick cover is sealed to the seat body, the air hole is sealed by the end face of the open end of the seat connecting sleeve, blocking the entrance of dust, effectively eliminating the hidden danger of damage to the LED wick caused by dust intrusion, extending the service life of the LED candlelight, and saving usage costs. The hot air inside the wick cover lifts the wick cover, the wick cover is detached from the seat body, and the inner wall of the connecting ring is fitted with the outer ring, preventing the gas exchanged between the inside and outside of the cavity from escaping to the outside of the outer wall of the seat connecting sleeve, thereby improving the gas exchange efficiency, better reducing the internal gas temperature of the wick cover, reducing damage to the LED wick, and extending the service life.

[0010] Preferably, the base body is provided with an electrical compartment located between the electrode connection device and the base connection sleeve. A heat-insulating partition is provided at the junction of the electrical compartment and the base connection sleeve. The heat-insulating partition isolates the heat within the wick housing from the electrical compartment, preventing damage to the electrical appliances within the compartment, reducing the failure rate of the LED candle lamp, and making it more reliable.

[0011] The beneficial effects of the present invention are as follows: when the LED candlelight is lit, the hot air inside the wick cover is automatically exchanged with the cold air outside, reducing the temperature of the LED wick and extending the service life of the LED candlelight. When the LED candlelight is extinguished, the wick cover is sealed to the base, preventing the outside of the wick cover from invading the inside of the wick cover, keeping the LED wick clean and ensuring good lighting effect.
