The light emitted by the LED21can fill the entire light head to the maximum extent and scatter outward through the light head housing, which can bring a better visual effect of simulating a candle flame. The upper edge of the light transmitting portion22is semi-elliptical, and the LED21member cannot move up and down in the light transmitting portion22restricted by the large chamber12to maintain stable light emitting.

In the specific embodiment, referring toFIG.1, the hollow sleeve3is further comprised, an end of the hollow sleeve3is inserted into the through hole11and interference-fitted with the through hole11to maintain the circumferential fixing of the hollow sleeve3and the light head housing1, and a wire for the light source4is further comprised to extend through the large chamber12from the interior of the hollow sleeve3, and there is a gap between the bottom end of the light head housing1and the hollow sleeve mounting hole511for the hollow sleeve3to be exposed. In this embodiment, the length of the exposed hollow sleeve3is 2˜7 mm, and in other embodiments, its length can be passively adjusted.

In this embodiment, the hollow sleeve3is made of plastic, which is black. The hollow sleeve3can protect the wire for the light source4. The one end of the hollow sleeve3inserted into the through hole11can make the light source2emit light like the wick of a candle, thereby improving the simulation of the flameless candle. The interference fit between the hollow sleeve3and the through hole11can achieve the circumferential fixation of the hollow sleeve3and the light head, and further achieve the effect of waterproof sealing.

In the specific embodiment, referring toFIG.1, a jointing part between the large chamber12and the light-transmitting chamber13comprises a position-limiting portion14for limiting the installation position of the light source2, and the position-limiting portion14has a concave profile matching with the outline of the light source2. The position-limiting portion14can clip the light source component, and the position-limiting portion14has a concave profile matching with the outline of the light source2, which can make the overall light source component simple to install inside the light head, so as to maintain the consistency of the installation position of the light source component.
