[0001] The invention relates to the technical field of lighting, and in particular to an LED flame lamp. Background Art

[0002] With the development of technology, in addition to the usual lighting function, some lamps also have decorative effects. For example, the most popular flame lamp that simulates the jumping and flashing effect of flame burning is one of them.

[0003] At present, there are two types of flame lamps on the market. One is the LED flame bulb dynamic simulation flame bulb, and the other is the LED fire basin simulation flame lamp. Half of the power of the LED flame bulb is less than 5W, and the brightness is insufficient. Since it has almost no waterproof performance, it cannot be used outdoors. Its flame effect can only be presented inside the bulb, and cannot be irradiated on the light-emitting carrier (such as walls, glass, trees, etc.) to present the flame effect; the LED fire basin produces the fire effect by the silk cloth swinging in the LED red light through the fan. Like the LED flame lamp, it is not waterproof, and the effect is not good in places with obvious wind outdoors, and the outdoor usability is poor. At the same time, it cannot present the flame effect on other carriers. Summary of the invention

[0026] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0027] like Figure 1-6An LED flame lamp shown includes a shell, a light source and a driving motor 10 arranged in the shell, and a straight-stripe lens 9, a color filter 6 and a first light-transmitting sheet 5 are arranged in sequence along the light emitting direction of the light source. The first light-transmitting sheet 5 is installed on the power end of the driving motor 10 so that the driving motor 10 drives the first light-transmitting sheet 5 to rotate. A plurality of refractive surfaces are formed on the surface of the first light-transmitting sheet 5. The color filter 6 includes at least three second light-transmitting sheets 61 with different colors and arranged in parallel with the straight-stripe lens 9. The straight-stripe lens 9 is suitable for refracting the incident light to pass through three second light-transmitting sheets 61 at the same time. The second light-transmitting sheets 61 can make the transmitted light have color. The first light-transmitting sheet 5 is suitable for refracting the light passing through the second light-transmitting sheet 61 through a plurality of refractive surfaces. After refraction, the light passes through the color filter 6 and the first light-transmitting sheet 5 in sequence and forms a flame-shaped light spot. In the present application, the three second light-transmitting sheets 61 are sequentially red, orange and yellow in the length direction of the straight-striped lens 9 downward so that the colors of the projected flame-shaped light spots are sequentially red, orange and yellow from top to bottom, which is similar to the colors of a burning flame. In addition, the three second light-transmitting sheets 61 can also be sequentially dark green, light green and white to form a color similar to a ghost fire. Other settings can also be used, which are not elaborated in the present application.

[0028] When working, the light source irradiates light onto the straight-stripe lens 9, which refracts the incident light and forms a long strip of light spot similar to a flame. The long strip of light spot passes through three second light-transmitting sheets 61 of different colors at the same time to form a light spot with multiple colors. Then the long strip of light spot is incident on the rotating first light-transmitting sheet 5 and refracted through multiple refractive surfaces to produce a dynamic projection effect, and the dynamic projection effect looks similar to the state of a flame burning.

[0029] The present application refracts the light emitted by the light source through the straight-strip lens 9 to form a long strip light spot similar to a flame, and then colors the long strip light spot in cooperation with the color filter 6 so that the long strip light spot after passing through the color filter 6 is similar in color to the flame, and then cooperates with the rotating first light-transmitting sheet 5 to make the long strip light spot produce a dynamic projection effect. The dynamic same effect looks similar to the state of the flame when burning, and the projection effect is good.

[0030] As for how the straight-stripe lens 9 makes the incident light form a long strip of light spot similar to a flame, it belongs to the prior art, so the shape and principle of the straight-stripe lens 9 are not explained in detail. The model of the straight-stripe lens 9 in this application is LL01CR-CA51090L06 straight-stripe lens.

[0031] Specifically, the light source is arranged in an inclined manner in the housing so as to project the light spot onto a wall or other vertical surface, and at the same time, the projected light spot is closer to a flame shape, and the projection effect is good.

[0032] More specifically, the upper end surface of the lamp housing 2 is arranged at an angle, which can cooperate with the light source arranged at an angle in the housing, thereby saving materials.

[0033] Specifically, the shell includes a lamp base plate 1 for mounting a light source and a driving motor 10, a lamp housing 2 mounted on the lamp base plate 1, and a glass 4 mounted on the lamp housing 2. A first mounting groove 21 is provided on the mating surface of the lamp housing 2 and the lamp base plate 1, and a second mounting groove 11 is provided on the lamp base plate 1 at a position corresponding to the first mounting groove 21. The first mounting groove 21 cooperates with the second mounting groove 11 to form a sealed cavity for mounting a sealing strip, so as to improve the sealing between the lamp base plate 1 and the lamp housing 2, and prevent water from penetrating from the gap between the lamp base plate 1 and the lamp housing 2, causing a short circuit of the light source, and then passing through the lamp housing. 2 is provided with a third mounting groove 22, the glass 4 is arranged in the third mounting groove 22, and a sealing ring is arranged on the fitting surface of the glass 4 and the lamp housing 2, and the glass 4 is pressed against the lamp housing 2 by using a pressing plate 3 arranged at the upper end of the lamp housing 2, so that the sealing ring arranged between the glass 4 and the lamp housing 2 is deformed and the gap between the glass 4 and the lamp housing 2 is sealed to prevent water from penetrating and causing a short circuit of the light source. By arranging a sealing ring between the lamp housing 2 and the glass 4 and the lamp bottom plate 1, the LED flame lamp of the present application has IP66 waterproof performance, can be used in environments such as open air, pools or lakes, and has a wide range of applications.

[0034] Specifically, a fixing plate 101 extends downward from the edge of the lamp base plate 1, and a mounting hole 102 for bolts to pass through is provided on the fixing plate 101, so that the LED flame lamp of the present application can be fixed to a wall or other vertical surface for easy use.

[0035] The light source includes an LED lamp bead 8 and a radiator 7 installed at the lower end of the LED lamp bead 8 to dissipate the heat generated by the LED lamp bead 8 when it is working and prevent the LED lamp bead 8 from being overheated and damaged. The radiator 7 is made of metal material and can quickly transfer heat to the shell and dissipate it through the shell. In addition, a plurality of heat dissipation blocks are formed at the lower end of the radiator 7 to increase the heat dissipation area and improve the heat dissipation effect.

[0036] The heat sink 7 is provided with a straight-striped lens 9 fixing plate 101 for installing the straight-striped lens 9 and a fixing frame for installing the color film 6 to facilitate the fixing of the straight-striped lens 9 and the color film 6. The fixing frame is provided with a card slot for installing the second light-transmitting film 61 to prevent the second light-transmitting film 61 from loosening during use and affecting the quality of the projected image.

[0037] Specifically, a fixing plate 101 for connecting the radiator 7 and the shell is also provided in the shell to improve the stability of the radiator 7. At the same time, the radiator 7 is arranged in a suspended state in the shell to avoid heat accumulation when the radiator 7 is installed at the bottom of the inner wall of the shell, and the radiator 7 is damaged after long-term operation.

[0038] Specifically, a side plate is extended from a side of the fixing plate 101 away from the radiator 7 , and the driving motor 10 is mounted on the side plate to improve the stability of the driving motor 10 when working.

[0039] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
