Embodiment Construction

[0014] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0015] In the embodiment of the present invention, the crystal-bonding area is set on the metal frame, and then the part of the metal frame where the crystal-bonding area is located is wrapped with fluorescent glue, so that the light emitted by the LED chip set in the crystal-bonding area excites the surrounding fluorescent glue to produce the desired color The light, thus solving the problem of LED filament blue leakage.

[0016] The implementation of the present invention will be described in detail below in conjunction with specific embodiments.

[0017] Such as Figure 1~4 As shown, the LED f...

Abstract

The invention is applied to the field of lighting technologies and provides an LED filament and a lighting device. The LED filament comprises a metal framework and fluorescence gel. At least one surface of the metal framework is provided with a solid crystal area, a plurality of LED chips are arranged on the solid crystal areas, and the portion, where the solid crystal areas are located, of the metal framework is covered with the fluorescence gel. In this way, light emitted by the LED chips on the solid crystal areas can excite the surrounding fluorescence gel to generate light in needed colors, and therefore the problem of blue leakage of the LED filament can be solved. Thus, the LED filament can be widely applied to various lighting devices and is excellent in lighting effect.

Description

technical field [0001] The invention belongs to the technical field of lighting, and in particular relates to an LED filament and a lighting device. Background technique [0002] At present, LED filament light source products mainly form circuit boards on transparent ceramic or glass substrates, so as to achieve the purpose of emitting light at a large angle. However, transparent ceramics and glass substrates are expensive, complicated to manufacture, low in thermal conductivity, and generally use less than 1W of power, and the finished package cannot fundamentally solve the problem of blue leakage. Contents of the invention [0003] The purpose of the embodiments of the present invention is to provide an LED filament, aiming at solving the problem of blue leakage in the existing LED filament. [0004] The embodiment of the present invention is realized in this way, an LED filament includes a metal skeleton and fluorescent glue, at least one surface of the metal skeleton ...
