[0003] The prior art is an LED lighting device with the structure of a household fluorescent lighting lamp. A plurality of LEDs are welded to a circuit board, and a lampshade, a base and two lamp holder side covers made of glass or engineering plastics such as PC (polycarbonate) are used. Assembled and sealed together, the circuit board is set on the base, there is a certain space between the bottom surface of the circuit board and the inner surface of the base, and the adaptive power supply is set in the LED lighting device; from the structural analysis, on the one hand, due to the overall sealing, the LED heats up Gathered in the LED lighting device, the high temperature will reduce the service life of the LED and increase the light decay; on the other hand, the user must reinstall the power supply when using it, which is inconvenient to use; on the other hand, because a single LED is a point The light source, the light has not been processed much, the feeling is not soft, and the user's eyes are prone to fatigue

[0004] Chinese invention patent ZL200310111977.2 discloses an LED lamp whose heat sink (i.e. the base) is in contact with the LED light source board (i.e. the circuit board equipped with LEDs) to achieve heat conduction. It does not disclose the structure of the heat sink , from the picture, this structure has heat dissipation effect, but the heat dissipation effect is not very good; and the circuit board is of ordinary type, and the heat conduction effect is relatively poor

The lampshade of the LED lamp is a convex lens structure, which enhances the light intensity emitted by the LED light source and expands the light emission angle of the LED, thereby realizing long-distance lighting. At the same time, the light intensity and illuminated area are significantly improved, making the LED The light is suitable for landscape lighting; but the light of this LED light is not soft, it is not suitable for home use, and the user's eyes are more prone to fatigue
