Description

Technical Field

[0001] This utility model relates to the field of LED lighting technology, specifically a dynamic LED flame lamp. Background Technology

[0002] Existing simulated flame lamps are complex in structure and expensive. The most common type on the market is to project LED light obliquely onto the flame plate and then use the principle of electromagnetic induction of coils to make the blades swing to achieve a simulated flame effect. Another type is to bind multiple rows of LEDs on the circuit board and then let the IC drive the upper, middle and lower or multiple layers to achieve a simulated flame effect.

[0003] The above two methods are too complex in structure and too costly. Therefore, we propose a dynamic LED flame lamp. Utility Model Content

[0004] One of the technical problems this application aims to solve is: how to provide a flame lamp that is simple in structure, low in cost, and has a more realistic effect.

[0005] To solve the above-mentioned technical problems, this application provides a dynamic LED flame lamp, including a driving power supply, a first metal conductor connected to the positive terminal of the driving power supply, a second metal conductor connected to the negative terminal of the driving power supply, and a driving IC. It also includes a plurality of light-emitting elements respectively connected to the metal conductors at the positive and negative terminals of the driving power supply, and from top to bottom at the far end of the driving power supply, they are the first light-emitting element, the second light-emitting element, and the third light-emitting element.

[0006] In some embodiments, the driver IC, the first light emitter, the second light emitter, and the third light emitter are integrally packaged to form a package, and the positive and negative conductors of the connecting circuit extend from the package to the outside.

[0007] In some embodiments, the device further includes a light-transmitting housing with a channel at its bottom, the channel being sized to correspond to the encapsulation body, and the top of the encapsulation body being flat and insertable into the light-transmitting housing.

[0008] In some embodiments, the encapsulation body is made of epoxy resin.

[0009] In some embodiments, the first light source projects light toward the top of the projection housing, the second light source projects light toward the top of the projection housing, and the third light source projects light toward the bottom of the projection housing.

[0010] In some embodiments, the brightness of the first light-emitting body is greater than the brightness of the second light-emitting body, and the brightness of the second light-emitting body is greater than the brightness of the third light-emitting body.

[0011] In some embodiments, the light-projecting housing is spindle-shaped, with its outline curving inward from the middle to both ends.

[0012] In some embodiments, the first light emitter and the second light emitter flash light, while the third light emitter remains constantly lit.

[0013] In some embodiments, the top of the package is flat.

[0014] This utility model has at least the following beneficial effects:

[0015] This dynamic LED flame light integrates light-emitting chips of different specifications with surface-mount light sources in a single package. By employing multi-level brightness control and dynamic flashing, it achieves a realistic flame effect with the inner flame flashing gradually brighter and darker, the outer flame breathing and flashing, and the flame core remaining constantly bright. It satisfies the three-layer structure of a flame and can realize three different color temperature LED lights to simulate the real combustion stage of a flame.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4This utility model provides a technical solution: a dynamic LED flame lamp, including a driving power supply 9, a first metal conductor 7, a second metal conductor 8, and a driving IC 3. The first metal conductor 7 is directly connected to the positive terminal of the driving power supply 9, and the second metal conductor 8 is connected to the negative terminal of the driving power supply 9. The device has multiple sets of light emitters, each set of light emitters being electrically connected to a corresponding positive or negative conductor. At a position far from the driving power supply 9, the first light emitter 4, the second light emitter 5, and the third light emitter 6 are arranged sequentially from top to bottom.

[0023] The driver IC3, along with the first light-emitting element 4, the second light-emitting element 5, and the third light-emitting element 6, are integrated into a single unit using integrated packaging technology, forming a robust package 2. This package 2 is molded from epoxy resin material, providing excellent sealing, insulation, and light transmittance. The positive and negative conductors of the internal circuitry extend outwards, facilitating external electrical connections.

[0024] The lamp has a light-transmitting outer shell 1 with a special channel at the bottom. The shape and size of the channel are precisely matched with the encapsulation body 2, so that the encapsulation body 2 can be smoothly inserted into the light-transmitting outer shell 1 by means of its top plane and maintain a stable position.

[0025] The overall shape of the projection shell 1 is spindle-shaped, with the outline curving inward from the middle to both ends, which helps to converge and diffuse light, creating a softer and more natural optical effect.

[0026] In terms of light projection direction, the first light emitter 4 and the second light emitter 5 both emit light towards the top of the projection housing 1, while the third light emitter 6 is designed to project light towards the bottom of the projection housing 1. The brightness of the three is specially adjusted: the first light emitter 4 has the highest brightness, the second light emitter 5 is next, and the third light emitter 6 has the lowest brightness, thus creating a rich and layered light effect that combines reality and illusion.

[0027] The first light source 4 and the second light source 5 emit light in a dynamic flashing mode to simulate the irregular shape of a flickering flame; the third light source 6 remains constantly lit to enhance the stability and realism of the flame effect. The top of the package 2 adopts a planar design, which facilitates assembly and also promotes uniform light emission.

[0028] In addition, it should be noted that the first light-emitting element 4 is a light-emitting chip, the second light-emitting element 5 is a light-emitting patch, and the third light-emitting element 6 is a light-emitting patch. The second light-emitting element 5 and the third light-emitting element 6 are connected to the positive and negative terminals in a bonding manner. When the battery pack supplies power to the LED pins, in the first stage, the lower part of the LED (flame core) remains constantly lit, illuminating the lower side of the floodlight housing. In the second stage, after the driver IC3 is powered on, it supplies power to L1 (inner flame), simulating the state of flame combustion with strobe and gradual brightening and dimming. At the same time, L2 (outer flame) moves up and down in coordination with L1 (inner flame) and flashes at different speeds to simulate the burning effect of flame in different states of wind and calm.

[0029] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
