LED flame lamp adopting flame light-emitting assemblies on both sides

Abstract

The invention discloses an LED flame lamp adopting flame light-emitting assemblies on both sides. The LED flame lamp comprises a lamp cap, a bulb shell, a light guide barrel and a flame light source board, wherein the bulb shell is arranged at the opening of the inner wall of the lamp cap, the light guide barrel is arranged in the bulb shell, the flame light source board is arranged in the light guide barrel, the flame light source board comprises a double-side circuit substrate, LED lamp beads and a drive power supply, the LED lamp beads are welded to the front and back sides of the double-side circuit substrate, the LED lamp beads and the drive power supply on the flame light source board can be welded to one double-side circuit substrate, so that the flame light source board in an integrated structure is formed, or the LED lamp beads and the drive power supply can be respectively welded to two circuit substrates, so that the flame light source board in split structures is formed. For the LED flame lamp adopting the flame light-emitting assemblies on both sides, the use number of the LED lamp beads can be greatly reduced, thus the manufacturing cost is reduced, in addition, the light emitting effect is softer, the luminance of the dark area is improved, the fixing effect of the flame light source board in the light guide barrel is improved, then the assembly efficiency can beimproved, the manual labor is reduced, the rejection rate is reduced, the automatic production is realized, and the market competitiveness of the product is strong.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of lighting fixtures, in particular to the technical field of an LED flame lamp using a double-sided flame light-emitting component. [0003] 【Background technique】 [0004] With the development of society and the improvement of people's material living standards, people's life taste and aesthetic level are also gradually improving. Bulbs and lighting decorations, as daily necessities commonly used by people, play an irreplaceable role in people's daily life. People's demand for these lighting and lighting decoration products is becoming more and more detailed, and the appreciation requirements are getting higher and higher. The very retro flame effect lighting can add more atmosphere and beauty to people's living space. [0005] Flame is the visible light or other physical manifestations that appear in the chemical process in which fuel and air are quickly transformed into combustion products. It i...

Problems solved by technology

Currently on the market is a kind of LED flame bulb that imitates the flame effect. It uses LED particles such as 2.8x3.5mm arrays on a flexible PCB circuit board. The flexible PCB board is pasted on a cylindrical tube and fixed to form a flame light source board like corn cobs. Through the driving power supply and control circuit, each LED lamp bead is driven to light and dark 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 distance (about 5mm) between the lamp beads and the lamp beads, resulting in this flame bulb in the 2m You can clearly see the light and dark changes of each LED inside the bulb. Only when you can’t see a single LED bead through a certain distance (about more than 2 meters), will there be a flame effect. This kind of The LED flame effect simulated by the LED flame lamp is not realistic enough and blunt. For example, the image distortion caused by the low display pixels of the early LED screen caused 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 holders), the diameters of the two ports of the LED cylindrical light-emitting body are relatively large (greater than 15mm), and the ports are the light-emitting tops of the bulbs without LED beads, 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 fixing effect of the soft board is not good and it is pasted by hand. The component structure is complicated. There are many LED lamp beads used in this kind of flame lamp, and the high cost is not conducive to automatic production. , which is not conducive to promotion and application
