A substrate (1) for LED packaging, an LED package (40), and an LED bulb. The substrate (1) is in a strip shape, at least one end of the substrate (1) is provided with an electrode leading wire (2), and the electrode leading wire (2) is connected to the substrate (1) by a connecting component (3) and/or a connecting material, wherein at least one hole (5) arranged along the length direction of the substrate (1) is provided on the substrate (1). The LED package (40) comprises the substrate (1), the substrate (1) is provided with a plurality of LED chips (10), and the plurality of LED chips (10) is connected in series and/or in parallel with each other by connecting wires (11). The LED bulb has the LED package (40). A hole (5) on the middle part of the substrate (1) makes arrangement and control of LED chips (10) on the substrate (1) more simple and diversified, thereby aiding in air ventilation and heat dissipation of the LED package (40), making the service life of the LED bulb longer, and making a light emitting angle more all-dimensional. |
