The invention discloses an LED (
Light Emitting Diode) device and an
LED lamp. The LED device comprises a substrate, a
first light transmission plate and a second
light transmission plate. A cavity isformed in the substrate, an LED
chip is arranged in the cavity, a stepped face is formed at an open end of the cavity, and a seal groove is formed in the
peripheral face of the cavity. The first lighttransmission plate is arranged on the stepped face. The second
light transmission plate comprises a
peripheral part and an intermediate part, an annular lug matched with the seal groove is arranged between the
peripheral part and the intermediate part, a
desiccant is used for filling between the peripheral part and the intermediate part, the thickness of the peripheral part is smaller than that of the intermediate part, the intermediate part is opposite to the cavity and presses the
first light transmission plate, a microporous layer opposite to the peripheral part is arranged on the peripheral face, a bonding
adhesive is used for filling between the peripheral part and the substrate and infiltrates into the microporous layer, a concave spherical face with an opening facing to the
first light transmission plate is formed in the intermediate part, and a plurality of glass micro-beads are arranged in the intermediate part. According to the LED device and the
LED lamp, outside corrosivesubstances are subjected to dual isolation, the
failure rate of the LED device can be effectively improved, and the LED device has an anti-dazzle effect.
