In a further technical solution, the second heat dissipation sealing ring is squeezed between the heat dissipation lamp body and the rear cover.

In a further technical solution, the first sealing ring and the second sealing ring are silicone rubber sealing rings.

In a further technical solution, the light transmittance of the diffusion plate is greater than 90%.

In a further technical solution, the waterproof joint is an M12 metal waterproof joint.

In a further technical solution, double clip springs are arranged symmetrically on both sides of the heat dissipation lamp body. The upper end of the double clip spring has two torsion arms. The lower end of the double clip spring is covered with a mounting sheath. The bottom end of the sleeve is provided with a groove stuck on the edge of the cover.

In a further technical solution, a plurality of grooves at the end of the installation sheath are arranged side by side.

In a further technical solution, an insulating sheet is further provided between the heat dissipation lamp body and the power supply assembly.

The utility model provides a waterproof grade IP66 anti-fog LED downlight. The interior of the lamp is compressed with an aging-resistant silicon rubber sealing ring, and the outlet is made of a metal connector with an anti-pull waterproof grade IP68, and the structure achieves waterproof performance. The design of the luminaire to increase the shading angle, and the lampshade adopts a diffuser plate with a light transmittance greater than 90, which can effectively control glare and ensure uniform light output.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in detail.

As shown in Figure 1 and Figure 2, a waterproof and anti-fog LED downlight provided by the utility model includes a face cover, a diffusion plate, a reflective film, an LED light board assembly, a heat dissipation lamp body, a power supply assembly and a rear Cover, the inner side of the cover is uniformly provided with a plurality of strip grooves to increase the shading angle. The strip grooves are located at the edge of the bottom of the cover and extend outward along the length direction of the downlight. The surface cover has a certain height, and the stripe design is adopted around it to increase the shading angle. The light-emitting surface uses a diffuser plate with high light transmittance, so that the light is uniform and achieves an anti-fog effect.

A first sealing ring is provided between the face cover and the heat dissipation lamp body, and the first sealing ring is sleeved on the edge of the diffuser plate and squeezed between the surface cover and the heat dissipation lamp body; a second sealing ring is arranged between the heat dissipation lamp body and the back cover Two sealing rings, the second heat dissipation sealing ring is squeezed between the heat dissipation lamp body and the back cover. The first sealing ring and the second sealing ring are silicone rubber sealing rings.
