Example Embodiment
[0015] Example one
[0016] Such as figure 1 As shown, an LED packaging structure includes a substrate 1, an LED chip arranged on the substrate 1, a filling gel 3 for sealing the LED chip 2, a phosphor layer 6, a first gel layer 4, and a second gel Layer 7; the first colloid layer 4 is wrapped around the filling colloid 3 and forms a cavity 5 between the filling colloid 3; the middle of the cavity 5 is thick and the edges are thin; the phosphor layer 6 is coated on the first colloidal layer 4; the second colloidal layer 7 is coated on the phosphor layer 6.
Example Embodiment
[0017] Example two
[0018] Such as figure 2 As shown, an LED packaging structure includes a substrate 1, an LED chip arranged on the substrate 1, a filling gel 3 for sealing the LED chip 2, a phosphor layer 6, a first gel layer 4, and a second gel Layer 7; the first colloid layer 4 is wrapped around the filling colloid 3, and forms a cavity 5 between the filling colloid 3; the phosphor layer 6 is wrapped in the first colloid layer 4 On; The second colloidal layer 7 is coated on the phosphor layer 6. The number of the LED chips 2 is greater than one, the surface of the filled colloid 3 has protrusions 301, and each protrusion 301 corresponds to one LED chip 2.
[0019] The light emitted by the LED chip 2 enters the filling colloid 3 and is refracted at the interface between the filling colloid 3 and the cavity 5. The blue light intensity is redistributed and reaches the phosphor layer 6 through the first colloid layer 4. Part of the blue light passes through the phosphor layer ...
