LED filament structure and LED lighting lamp based on LED filament structure

Abstract

The invention provides an LED filament structure and an LED lighting lamp. The LED filament structure comprises a base plate, an LED chip component, a fluorescent material layer and light filter material layers, wherein the LED chip component comprises at least one first LED chip and at least one second LED chip, separation distances exist between the adjacent LED chips, the fluorescent material layer wraps all the LED chips, the light filter material layers are covered on the surfaces of any one of the first LED chips and the second LED chips, when the LED filament structure is just on, the light filter material layers are opaque to light, the fluorescent material layer is made to give off light of first color temperature, in preset time after the filament structure is on, the light filter material layers become transparent gradually, light given off by the first LED chips and the second LED chips both can excite the fluorescent material layer to give off light of second color temperature, and the second color temperature is different from the first color temperature. The LED filament structure and the LED lighting lamp are based on the light filter material layers, by means of change of the environment (such as light and heat), change of the color temperature and brightness of the filament lamp is achieved, the LED filament structure and the lighting lamp are made to approximate an incandescent lamp, the LED filament structure and the LED lighting lamp are simple in structure and easy to realize, a production process is similar to that of the incandescent lamp, and production is facilitated.

Description

technical field [0001] The invention belongs to the technical field of lighting devices, in particular to an LED filament structure and an LED lighting lamp. Background technique [0002] With the development of society and the improvement of people's living standards, more and more lighting products are used by people. The traditional LED bulb lamp adopts a flat PCB (Printed Circuit Board) circuit board, on which the LED package is solid-sealed, and a heat sink is arranged under the PCB to dissipate heat. However, such LED bulbs cannot achieve 360-degree full-circle lighting. In addition, the appearance of such LED bulbs is quite different from traditional incandescent lamps, which is not beautiful enough; the production process is very different from that of incandescent lamps, and incandescent lamp manufacturers are also There are no conditions for production. [0003] In order to be closer to the traditional tungsten filament lamp, to achieve full-circle light, and to ...
