This application claims priority of a Chinese patent application No. 2023212091665 filed on May 18, 2023, the entirety of which is incorporated by reference.
The present disclosure relates to the technical field of a flameless candle, in particular to a light head for a flameless candle, a lighting assembly and a flameless candle.
Traditional candles are ignited by an open flame, which produces a large amount of heat and poses a certain safety hazard due to the risk of tipping over and igniting flammable materials. The large amount of black smoke generated during combustion causes environmental pollution, and the melted wax can burn the user. The light intensity and service life are further difficult to meet practical needs.
With the improvement of people's living standards, candles are no longer just used as lighting tools. They are often used to change the indoor atmosphere, and the soft candlelight can further bring pleasure and relaxation to people. Currently, flameless candles are gradually replacing traditional candles. The flameless candles not only have lighting functions but can further be designed to have viewing and entertainment functions, such as electronic flashing candles, music candles, and simulated kerosene lamps. However, there is currently no product that effectively protects the body structure of flameless candles.
The U.S. Pat. No. 10,436,396B2 discloses an artificial candle, comprising a hollow cylinder, an electric wire, and a light bulb. The light bulb comprises a light source with a long strip shape, a cup sleeved on and fixed to the electric wire at a position near the first end of the wire, an outer cover covered on the cup, and an inner cover sleeved on the light source and defining a receiving space for receiving a part of the light source and the second end of the electric wire. The light transmitted of the inner cover is smaller than that of the outer cover and that of the cup. The inner cover is configured for reflecting light emitted from the part, received in the receiving space, of the light source towards the wire holder and an exposed part of the electric wire. A simulation effect of the flame is improved.
However, the above-mentioned technical solution has the following defects: the part of the wire that is connected to the housing and the wire support of the artificial candle is exposed without protection, making it vulnerable to damage. Additionally, the artificial candle does not have a lighting assembly to protect it, and water can leak into the lamp body when it encounters water, making it unusable or causing dangerous accidents. Therefore, the overall safety of the artificial candle is insufficient.
In view of the shortcomings of the prior technology, the present disclosure aims to provide a light head, a lighting assembly and a flameless candle with the advantage of having a lighting assembly protecting the flameless candle.
