Embodiment Construction

[0028] 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.

[0029] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or it may be indirectly fixed or disposed on the other element through a third component. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or it can be indirectly connected to the other element through a third element.

[0030] It should also be noted that the orientation terms such as left, right, up, and down in this embodiment are only relative concepts or refer to the norm...

Abstract

The invention relates to the technical field of LED semiconductor lighting, and provides an LED filament light source and a manufacturing method thereof, comprising a substrate, an insulating layer, a metal circuit layer, a lens, and a plurality of LED flip-chips. An insulating layer, each insulating layer is provided with a metal circuit layer, the pins of each LED flip chip face the metal circuit layer, and each pin is welded on the metal circuit layer to be electrically connected with the metal circuit layer, and the lens is packaged on each LED flip chip chip periphery. The LED filament light source realizes uniform light output on both sides, and achieves the brightness consistency of the light output in a 360-degree filament space, that is, realizes full-angle three-dimensional light emission of the LED filament light source, and has better heat dissipation at the same time.

Description

technical field [0001] The invention relates to the technical field of LED semiconductor lighting, in particular to an LED filament light source and a manufacturing method thereof. Background technique [0002] At present, the luminous efficiency of LED is much higher than that of incandescent lamps, and it has begun to enter the field of general lighting, which accounts for 30-40% of global power consumption, and has become an important way to significantly reduce lighting power consumption and save energy. It can be seen that LED lighting will continue to innovate in the direction of high efficiency, energy saving, clean environmental protection and high cost performance, and promote the implementation of global energy saving and emission reduction projects. But LED has been struggling to enter the field of general lighting. Although the packaging of the large-angle LED light source allows the LED to achieve the excellent effect of wide-angle lighting, this wide-angle has...
