Patent ID: 10794543

Abstract:
The invention provides a substrate for LED packaging, a LED package and a LED bulb. The substrate is in a strip shape, at least one end of the substrate is provided with an electrode lead-out wire. The electrode lead-out wire is connected to the substrate by a connecting component and/or a connecting material, wherein at least one opening arranged along the length direction of the substrate is provided on the substrate. The LED package comprises the substrate, the substrate is provided with a plurality of LED chips, and the plurality of LED chips are connected in series and/or parallel with each other by connecting wires. The LED bulb of the present invention has the LED package. According to the invention, the openings in the middle part of the substrate make the arrangement and control of the LED chips on the substrate simpler and more diversified, which facilitates the air ventilation and heat dissipation of the LED package, makes the service life of the LED bulb longer, and makes the emitting angle more all-directional.
