Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, so that those skilled in the art of the present invention can easily implement the present invention.

[0033] Such as Figure 1-2 As shown, it is a structural schematic diagram of the present invention. The present invention provides a LED surface light source light engine based on honeycomb arrangement, which is composed of LED lamp beads 4, aluminum substrate 1, fluorescent layer 5, insulating layer 2 and conductive copper foil 3. The aluminum substrate 1 is the physical carrier of the light engine, located at the bottom layer, which can effectively and quickly dissipate the heat generated by the LED lamp bead 4 during operation; the thickness of the aluminum substrate 1 can be 0.5mm, 1.0mm, 1.2mm, 1.6mm, 2.0mm , pure aluminum plates with thermal conductivity of 1.0, 2.0, 3.0; the aluminum substrate 1 can also be replaced by a flexible circuit board, a...

Abstract

The invention relates to an LED surface light source light engine based on honeycomb arrangement and a production method thereof. The technical problems of the existing dot matrix lighting lamps and COB type lighting lamps are solved. The light engine has a substrate on which an insulating layer is arranged. A conductive copper foil is arranged on the insulating layer. LED lamp beads are arranged at the conductor nodes of the conductive copper foil. The LED lamp beads are flip-over LED lamp beads, and the flip-over LED lamp beads are of a low-power type. The flip-over LED lamp beads and the conductive copper foil are arranged and connected in a honeycomb structure. The LED surface light source light engine of the invention can be widely applied to the technical field of LED surface light source lighting.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to a honeycomb-arranged LED surface light source light engine and a production method thereof. Background technique [0002] With the large-scale and widespread application of LED lighting fixtures, the design and packaging technology of LED light engines are gradually becoming more and more mature. LED light engines have undergone rapid development over two generations of dot-matrix and COB models. These two models currently have a large number of applications in the market. [0003] However, as LED lighting fixtures enter thousands of households, the inherent shortcomings of dot matrix and COB LED lighting fixtures are becoming more and more obvious. Dot-matrix lighting fixtures have a relatively high glare value. In most application places, users report that the lighting fixtures are very uncomfortable to look at; COB lighting fixtures, because the heat generated by themselves ...
