Embodiment 1
[0028] like figure 1 As shown, the LED device includes a substrate 10, a chip 20, a package structure 30 and a top reflective shielding layer 40, wherein the chip 20 is arranged on the substrate 10; the package structure 30 is covered on the substrate 10 and covers the chip 20; the top reflective shielding layer 40 It is arranged on the encapsulation structure 30 and is located at the center of the upper surface of the encapsulation structure 30 and covers a part of the upper surface of the encapsulation structure 30 .
[0029] By arranging the top reflective shielding layer 40 on the package structure 30 and at the center position of the upper surface of the package structure 30, while the top reflective shielding layer 40 covers a part of the upper surface of the package structure 30, so that the light emitted from the front side of the chip 20 Partial reflection is carried out, so that while the LED device has five-sided light emission, the setting of the top reflective shi...
Embodiment 2
[0038] like figure 2 As shown, the difference between this embodiment and Embodiment 1 is that the LED device further includes a peripheral reflective shielding layer 50 , and the peripheral reflective shielding layer 50 covers the outer peripheral side of the encapsulation structure 30 . In this way, by setting the peripheral reflective shielding layer 50 on the outer peripheral side of the packaging structure 30 of the LED device, the circumferential light-emitting characteristics of the LED device are optimized, ensuring that the LED device can emit uniform light in the horizontal direction, and further improving the performance of the LED device. luminescence properties.
[0039] In this embodiment, optionally, the peripheral side of the peripheral reflective shielding layer 50 is a rough surface with an embossed structure.
[0040] Optionally, the embossed structure includes a plurality of prisms or prism grooves distributed in an array. When the embossed structure incl...
