Embodiment 1
[0030] Such as figure 1 , figure 2 As shown, the LED fluorescent lamp includes a PC lampshade, LED, reflective film, printed circuit board and lamp holder as an integrated structure. There are several LEDs on the printed circuit board. The LEDs use medium and high-power LEDs. The quantity is less than 100 pieces. The LED light-emitting surface is covered with a high-reflection film except for the LED light-emitting point. The high-reflection film can be made of, for example, E6QV material, or it can be sprayed or printed with a high-reflection material. The integrated structure of the printed circuit board and the lamp holder is formed by bonding the insulating layer and the circuit layer to the lamp holder with pressure-sensitive adhesive or directly. The insulating layer is composed of epoxy film, glass fiber cloth or polyimide, and the circuit layer is etched copper foil. A built-in power supply is arranged in the lamp holder, and the built-in power supply adopts a high...
Embodiment 2
[0032] Such as image 3 , Figure 4 As shown, the difference from Embodiment 1 is that the integrated structure of the printed circuit board and the lamp holder can be a sunken trapezoidal structure.
Embodiment 3
[0034] Such as Figure 5 , Figure 6 As shown, the difference from Example 1 is that a groove is provided on the top surface of the lamp holder, and a printed circuit board is arranged in the groove, and the top surface of the lamp holder is covered with a high-reflection film, and a high-reflection material can also be sprayed or printed on the surface .
