Description

An LED flame lamp using double-sided flame light-emitting components

【Technical field】

The invention relates to the technical field of lighting lamps, in particular to the technical field of an LED flame lamp using a double-sided flame light-emitting assembly.

【Background technique】

With the development of society and the improvement of people's material living standards, people's life taste and aesthetic level are gradually improving. As the daily necessities commonly used by people, light bulbs and lighting have an irreplaceable role in people's daily life. People's demand for these lighting and lighting decoration products is becoming more and more refined, and the appreciation requirements are also getting higher and higher. The very retro flame effect lighting can add more atmosphere and beauty to people's living space.

Flame is visible light or other physical manifestations in the chemical process that fuel and air are rapidly transformed into combustion products after mixing. It is a chemical phenomenon and also a physical phenomenon. The chaotic shaking (magic) movement, string movement, and light and dark colors of the flames give people a very aesthetic visual experience. An LED flame bulb that imitates the flame effect currently on the market uses LED particle lamp beads, such as a 2.8x3.5mm array, which is arranged on a flexible PCB circuit board. The flexible PCB board is pasted and fixed on a cylindrical tube to form a flame light source board like a corn cob. The light and dark of each LED lamp bead is driven by the driving power supply and control circuit to form a series of LED lights on the flame light source board. Change, the light passes through the white plastic bulb to generate a simulated flame. Since these LED lamp beads are arranged in a dot matrix, there is a gap (about 5mm) between the lamp beads and the lamp beads, resulting in this flame bulb at 2m. You can clearly see the light and dark changes of each LED inside the bulb. Only through a certain distance (about 2 meters) can not see a single LED light bead, will there be a flame effect. The LED flame effect simulated by the LED flame lamp is not realistic and rigid. For example, the image distortion caused by the low display pixels of the early LED screen causes the flame effect to be unreal. It can only simulate the effect of flame jumping, but cannot simulate the fog of the flame. bridging effect. Especially for large-sized flame bulbs (such as flame bulbs with E26/27 lamp caps), the diameter of both ends of the LED cylindrical light-emitting body is large (greater than 15mm), and the light-emitting top of the bulb is not provided with LED lamp beads at the port, resulting in the top of the bulb. There are also dark areas. In addition, the curling of the soft board also causes poor damage. The soft board has a poor fixation effect and is pasted by hand. The component structure is complex. There are many LED lamp beads for this type of flame lamp, and the cost is high and it is not conducive to automated production. , which is not conducive to promotion and application.

[Content of the invention]

The purpose of the present invention is to solve the problems in the prior art, and to propose an LED flame lamp using a double-sided flame light-emitting assembly. The flame light source board is a double-sided circuit substrate with LED lamp beads welded on the front and back. The substrate is a thin plate with a certain hardness of about 1mm. The material can be a glass fiber substrate or an aluminum substrate. After the drive and control circuit components are electrically connected, the LED lamp beads, the drive power supply and the control circuit adopt a split design structure. The shape of the light guide tube is cylindrical, the light of the flame light source board can be directly emitted from the openings at both ends or one end, and the side wall forms a closed loop for the internal light path. On the blister, the light guide tube can be made of plastic, light-transmitting materials such as glass, plastic, silica gel, and resin. In order to simulate the flame burning state, when the LED lamp beads on the front and back sides of the double-sided circuit board are working, they show regular bright and dark flickering changes. Bottom to top), the bright and dark flashing speed of the LED lamp bead is from constant on or micro-flash to fast cyclic flashing, specifically, the lower LED lamp bead is set to be always on or micro-flash mode, simulating the continuous burning effect of the flame, the middle LED The lamp bead is set to slow flashing mode to simulate the shaking effect of fire, and the upper LED lamp bead is set to fast flashing mode to simulate the effect of flame string movement. Through the light and shadow changes caused by the multi-level light and dark flickering from bottom to top, it gives people a visual perception of a cyclically progressive, jumping and burning flame. Because the LED lamp bead is a granular single-sided point-like light-emitting mode, the edges of the flame light source board cannot emit light. When the flame light source board is working, its visual experience is a two-sided light, which has a jumping motion and can emit granular dazzling light. This flame light source board constitutes the initial outline of the flame light source inside this series of flame lighting such as the LED flame light bulb; in order to eliminate the graininess and the glare of the LED light, the transparency range of the light guide tube is any transparency, and the transparency and guide The color of the light tube also depends on the color of the LED lamp bead, the bulb shell or the requirements of the application scene with the corresponding color and transparency. Usually, under the condition that the LED lamp bead emits light at the color temperature of the flame, the light guide tube is milky white or light yellow. In order to compensate the brightness of the non-LED light-emitting area and the graininess of the atomized lamp beads, the surface of the light guide tube is usually frosted or added with light diffusing material inside, or there are concave-convex prism patterns on the wall of the light guide tube to change and divide The light guide also filters the light color of the flame light source board, which can change and balance the color of the flame, and can weaken and atomize the particle and glare of the lamp beads to varying degrees. The effect is realistic, three-dimensional three-dimensional light and a flame effect bridged by fog. The flame light source board is set in the light-emitting position in the light guide tube. When the flame light source board is working, a part of the light will produce a series of optical phenomena such as repeated superimposed reflection and diffuse reflection in the closed loop area formed by the inner wall of the light guide tube, so that part of the light will follow the guide. The wall of the light tube is diffused in all directions, part of the light will be refracted through the side wall of the light guide tube, and some will be emitted from both ends of the light guide tube. The optical phenomenon caused by the change of these light paths makes the whole body of the light guide tube covered by the light of the flame light source board. Rendered and illuminated, and has external three-dimensional light-emitting characteristics. After this LED flame light-emitting component is equipped with a corresponding light-transmitting bubble, it can be seen that there will be a three-dimensional flame burning effect bridged by three-dimensional fog inside the bubble.

The LED flame lighting assembly has a simple structure and few components. In particular, the double-sided light-emitting source of the circuit board is used to replace the cylindrical (column) light-emitting source made by the curling and pasting process of the flexible circuit board. It reduces the usage of LED lamp beads, improves production efficiency, saves a lot of labor and materials, and facilitates the assembly of various bulbs and lighting products in the later stage. cost, and enhance the competitiveness of products; the spatial structure, surface geometric characteristics and intrinsic transparency of the light guide tube have a series of optical characteristics generated by the change of the light path, so that the LED flame light-emitting component has the ability to adapt to different bulbs, lighting and use. The ability to flexibly adjust flame characteristics such as flame chromaticity, lamp bead atomization, light softness, and dark area replenishment according to the needs of the environment can enable LED flame bulbs and lighting to produce a three-dimensional fog-bridging flame effect. Let consumers get a new visual experience of LED flame burning.
