Embodiment Construction

[0006] The present invention as figure 1 shown

[0007] The alternating current is connected to the LED constant current driver 7 through the alternating current contact point 6, and after passing through the constant current driver, it is connected to the circuit 3 of the conductive silver glue through a wire. The LED chip 1 is welded on the positive and negative poles of the conductive silver glue circuit. The heat generated by the LED chip passes through the heat-conducting insulating plastic base 4 to transfer heat and diffuse into the air. 2 is an LED fluorescent lamp lampshade, and 5 is an insulating lamp holder.

[0008] The effective effect of the present invention is: first, the conductive silver glue is printed on the plane of the plastic base of the heat-conducting and insulating LED fluorescent lamp according to the required circuit by screen printing technology, and the alternating current passes through the AC contact point of the LED fluorescent lamp to connec...

Abstract

The invention belongs to the field of LED fluorescent lamp illumination, and relates to an all-plastic heat-conducting insulating type LED fluorescent lamp production method. A circuit is formed by printing conductive silver adhesives on the plane of a heat-conducting insulating plastic base via the screen printing technique. A conventional aluminum substrate and a fiberglass insulation layer are omitted, an LED chip is directly welded on the conductive silver adhesive circuit, heat produced by the LED chip is quickly transmitted from the heat-conducting insulating plastic base into air, the temperature of the LED chip is lowered effectively, and the problem of luminous attenuation of the LED chip is solved.

Description

Technical field: [0001] The invention relates to the lighting field of LED fluorescent lamps, and uses all-plastic heat-conducting insulating materials to make LED fluorescent lamps. Background technique: [0002] LED fluorescent lamps are energy-saving and environmentally friendly new lighting fixtures, and the market demand is huge. But it is also necessary to use metal materials as heat sinks. Invention content: [0003] The object of the present invention is to provide an all-plastic heat-conducting and insulating LED fluorescent lamp, which can replace the use of metal heat sinks. The LED fluorescent lamp is made according to the conventional circuit method, and a layer of glass fiber is laid on the aluminum substrate as the insulating layer. Then cover with copper foil, after chemical etching to form a circuit, solder the LED chip on the circuit. In this way, the heat of the chip is transferred through the glass fiber layer, and then transferred to the back cover m...
