Description

A kind of LED candle light

technical field

The invention belongs to the technical field of LED lamps and relates to an LED candle lamp.

Background technique

In order to pursue a comfortable and elegant living space, people are very particular about the structure of the indoor environment atmosphere. In addition to interior decoration, candles are often used to change the indoor environment atmosphere. However, traditional candles will generate a lot of heat when lit with an open flame. Often due to the negligence of the user, flammables are ignited due to dumping, which has certain safety hazards and also caused environmental pollution, and the hands cannot be touched directly, otherwise it is easy to be scalded by the melted wax liquid, and the service life of the wax body is also very short. Short and burns out quickly.

With the development of society, electronic candle lights have appeared. Electronic candle lights can simulate the lighting effect of real candles through the light projected by electronic candles. Therefore, they have been widely used in bars, cafes, and dance halls. widely used. However, the existing electronic candle lights only rely on their appearance to be close to real candles to achieve a certain simulation effect, and still cannot simulate the flickering of the candle flame and the light and dark changes of light caused by the air flow of real candles.

Contents of the invention

The object of the present invention is to solve the above-mentioned problems existing in the existing candle-type electronic lamps, and propose an LED candle lamp which can simulate the effect of changing the brightness of the light caused by the flickering of a real candle.

The purpose of the present invention can be achieved through the following technical solutions: an LED candle lamp, including a base and an LED driver circuit board group and a substrate arranged in the base, one side of the substrate is provided with an LED lamp and a candle covered on the LED lamp core, and the other side is connected to the above-mentioned LED driver circuit board group, and it is characterized in that a swing mechanism that can control the LED lamp to swing slightly in the horizontal direction is also provided between the LED lamp and the substrate.

After the LED emits light, the light shines on the inner wall of the candle wick. Because the candle wick is generally made of transparent or translucent materials, this makes the candle wick a luminous body, which is used to simulate the wick of a real candle. When the LED lamp oscillates under the control of the oscillating mechanism, each luminous part of the candle wick changes in brightness and darkness.

In the above-mentioned LED candle lamp, the swing mechanism is a spring, one end of the spring is fixedly connected to the substrate, the other end is connected to the LED lamp and the LED lamp is suspended in the air, and the gap between the LED lamp and the LED driving circuit board group The connection is made via a wire.

In the aforementioned LED candle lamp, a cycloid is provided at the top of the candle wick, and a transparent sphere is fixedly suspended from the end of the cycloid, and the sphere is just above the LED lamp.

If the length of the spring is too short, it will affect the swing effect of the LED light, and if the length of the spring is too long, it will be easily bent by the LED light after swinging and cannot be reset. Therefore, we add a transparent sphere inside the candle wick, let the light of the LED light shine on the sphere first, and then use the refraction effect of the sphere to make the sphere a luminous sphere, so that the wick glows more evenly. Moreover, when the LED lamp is swinging, the sphere can also swing together, and the light and dark changes of the light-emitting part of the candle wick are more obvious.

In the aforementioned LED candle lamp, a vibrating device capable of vibrating intermittently is further provided on the substrate. When the LED candle lamp is placed in a place where vibration is not easy to occur, the vibration device can be used to control the swing of the LED.

In the aforementioned LED candle lamp, the substrate is made of aluminum. The cooling effect is better.

In the aforementioned LED candle lamp, the base is made of ceramic material. The secondary heat dissipation can be formed together with the above-mentioned aluminum substrate, and the heat dissipation effect is good.

Compared with the prior art, the LED candle lamp relies on a swinging device to control the LED lamp to sway, so as to simulate the change of light and shade caused by the swaying of the wick of a real candle, and the simulation effect is better.

Detailed ways

The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

As shown in Figure 1, this LED candle lamp comprises ceramic base 1, and one end of ceramic base 1 is connected with candle head lampshade 5, and the other end is connected with lamp holder 8, and candle head lampshade 5 is a curved surface cover, and candle head lampshade 5 is shaped on opening. The ceramic base 1 is installed with an LED driving circuit board group 2 and an aluminum substrate 9, and the aluminum substrate 9 is equipped with an LED lamp 3 and a candle wick 4 covering the LED lamp 3 on one side, and is connected with an LED driving circuit board group on the other side. 2. The LED driving circuit board set 2 is electrically connected to the lamp holder 8 .

A spring 6 is fixed on the side of the aluminum substrate 9 facing the LED lamp 3, one end of the spring 6 is fixedly connected to the aluminum substrate 9, the other end is connected to the LED lamp 3 and the LED lamp 3 is suspended in the air, and the LED lamp 3 and the LED driving circuit The board groups 2 are connected through a wire 7 . A cycloid 12 is arranged on the top of the inside of the candle wick 4 , and a transparent sphere 10 is fixedly suspended from the end of the cycloid 12 , and the sphere 10 is just above the LED lamp 3 .

After the LED lamp 3 emits light, the light first shines on the sphere 10. By the refraction effect of the sphere 10, the sphere 10 becomes a luminescent sphere. A luminous body that emits relatively uniform light is used to simulate the wick 4 of a real candle. When there is a certain vibration, the spring 6 drives the LED lamp 3 at the end to sway, and the position of the LED lamp 3 irradiated on the sphere 10 is shifted, causing the sphere 10 and the candle wick 4 to become a luminous body with uneven light emission , resulting in changes in the brightness and darkness of the external perception. With the continuous swing of the spring 6, the brightness of the light-emitting part of the entire candle wick 4 is also constantly changing.

The candle lamp in this embodiment is only for simulating the change of the light and darkness of the candle, has added a lampshade 5, therefore also has relatively big difference with the real candle in appearance, if want to simulate the candle more realistically, Just change the appearance of the external candle light.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which the present invention belongs can make various modifications or supplements to the described specific embodiments or adopt similar methods to replace them, but they will not deviate from the spirit of the present invention or go beyond the definition of the appended claims range.
