[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] refer to Figures 1 to 4, a flame lamp of the present embodiment includes a bracket 1 with a conical outer wall, the top of the bracket 1 has a sunken arc concave surface 11, and the arc concave surface 11 is a reflective surface; a first lamp board 12 is fitted on the outer wall of the bracket 1, and a plurality of first LEDs 121 are regularly or irregularly distributed on the first lamp board 12; a control circuit board 2 is arranged inside the bracket 1, and a light-emitting body 3 that can flash and emit light and is electrically connected to the control circuit board 2 and passes upward through the center of the arc concave surface 11; and a cylindrical transparent lampshade 4 is coaxially sleeved and fixed to the outside of the bracket 1 and has a top edge higher than the bracket 1, the inner wall of the transparent lampshade 4 is formed with a grating texture 41 that is arranged circumferentially and parallel to the axial direction and densely distributed; the grating texture 41 causes the light and shadow emitted by each first LED 121 and the light-emitting body 3 to be axially elongated and diffused, thereby forming a light and shadow like an active volcano.

[0021] When in working state, the conical bracket 1 is used to simulate the shape of a volcano, and the first LEDs 121 on the surface of the first light panel 12 emit light to simulate flames scattered on the hillside, while the light-emitting body 3 on the top flickers and is reflected upward by the arc concave surface 11, which can simulate the shape of the crater and the effect of flame eruption; and the light output from the first LED 121 and the light-emitting body 3 is diffused and axially stretched by the grating texture 41, which not only avoids the light and shadow from being too bright and dazzling, but also blurs the edges of the light and shadow and expands the outline, making the flame effect more realistic.

[0022] A preferred solution, the light-emitting body 3 of this embodiment includes a second lamp board 31, a plurality of second LEDs with regular and / or irregular brightness and / or on-off changes arranged on the surface of the second lamp board 31, and a light-transmitting colloid 32 encapsulated on the periphery of the second lamp board 31 and simulating the shape of a flame. Specifically, a plurality of second LEDs are provided on the surfaces of both sides of the second lamp board 31, and are controlled by the control circuit board 2 to flash alternately, thereby simulating the dynamic light and shadow effects of a burning flame; the light-transmitting colloid 32 in the shape of a flame is directly encapsulated on the surface of the second lamp board 31, which can not only diffuse the light and shadow emitted by the second LED and make the light evenly diffused, but also form an integrated structure with the second lamp board 31 to realize mass production. Compared with the existing structure with a detachable lamp head, it can save the subsequent assembly and the resulting defects, and has a good waterproof effect.

[0023] A preferred solution is that the bottom end of the bracket 1 of this embodiment is integrally formed with a cylindrical mounting seat 13. The diameter of the mounting seat 13 is adapted to the inner diameter of the transparent lampshade 4, and the mounting seat 13 and the interior of the bracket 1 form an installation space; the mounting seat 13 has a battery compartment 5 stuck in it, the control circuit board 2 is vertically fixed to the top surface of the battery compartment 5, and the second lamp board 31 of the light-emitting body 3 is an integrally formed structure with the control circuit board 2, so that a rigid integrated connection structure is formed between the battery compartment 5, the control circuit board 2 and the light-emitting body 3. During assembly, it is only necessary to snap the battery compartment 5 and the control circuit board 2 upward into the mounting seat 13. Compared with the existing method of assembling the various parts of the flame lamp by welding wires, the assembly efficiency and product structure reliability are greatly improved.

[0024] In a preferred embodiment, the bottom diameter of the bracket 1 is smaller than the outer diameter of the mounting base 13, so that the top surface of the mounting base 13 forms an annular platform surface 131. The platform surface 131 creates a spacing between the bottom end of the bracket 1 and the inner wall of the transparent lampshade 4. This spacing creates a certain distance between each first LED 121 at the bottom of the side wall of the bracket 1 and the transparent lampshade 4, thereby preventing the light and shadow from these first LEDs 121 from being too glaring and having a sharp edge.

[0025] In a preferred embodiment, the upper portion of the luminous body 3 of the present embodiment exceeds the top of the bracket 1. The flickering light and shadow of the upper portion of the luminous body 3 can simulate the light and shadow effect of flames bursting out of the crater, further improving the simulation effect.

[0026] In a preferred embodiment, the first light panel 12 is electrically connected to the control circuit board 2, and each of the first LEDs 121 exhibits regular and / or irregular variations in brightness and / or brightness. The light and shadow of each first LED 121 changes according to the settings, simulating the effect of flames scattering across a hillside, further enhancing the simulation effect.

[0027] In a preferred embodiment, the grating texture 41 of this embodiment is distributed at least along the axial height portion from the top edge of the transparent lampshade 4 to the bottom edge of the bracket 1. Furthermore, the slits of the grating texture 41 are 0.5 mm wide and 0.07 mm deep. This slit arrangement optimizes light and shadow diffusion and elongation.

[0028] The above description does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
