[0015] The present invention will be further described in detail below in conjunction with the accompanying drawings.
[0016] See figure 1 The light-emitting diode 10 provided by the present invention includes a substrate 130 having a circuit structure, at least one light-emitting diode chip 120 and a packaging material 110. The light emitting diode chip 120 is disposed on the substrate 130 and is electrically connected to the circuit structure of the substrate 130. The electrical connection mode of the circuit structure of the light-emitting diode chip 120 and the substrate 130 can be a wire bonding connection or a flip chip connection. The substrate 130 may be a PCB substrate, a ceramic substrate, a metal substrate, or a flexible substrate. The packaging material 110 covers the light emitting diode chip 120. The refractive index of the packaging material 110 is 1.4-1.5. The packaging material 110 may include a fluorescent substance.
[0017] The packaging material 110 includ...
