Abstract

An underground lamp includes a lamp body, a seal ring, a reflection cup and a panel. The seal ring and a reflection cup provided with a support ring are adopted, and the support ring and the seal ring together support the panel so as to form a buffer space between the panel and the lamp body, thereby reducing the risk of damaging the panel caused by being pressed.

First claim

The invention claimed is:

1. An underground lamp, comprising:
a lamp body, a seal ring, a reflection cup and a panel, wherein:
the lamp body has an installation cavity, the installation cavity has an installation port, the installation port has an installation port outer edge, and the lamp body further has an abutment ring protruding from the installation port outer edge and circumferentially surrounding the installation port;
the reflection cup is disposed in the installation cavity, the reflection cup has a light exit cavity opening, the light exit cavity opening has a light exit cavity opening outer edge, the reflection cup further has a support ring protruding from the light exit cavity opening outer edge, the support ring is made of an elastic material, the installation port has an installation port inner edge, and the installation port inner edge has an abutment step circumferentially surrounded by the installation port; and
the panel covers the abutment ring and is fixed to the lamp body, the seal ring is disposed between the abutment ring and the panel, the seal ring is pressed by the panel and the abutment ring in cooperation, the support ring is disposed between the abutment step and the panel, and the support ring is pressed by the panel and the abutment step in cooperation,
wherein the rotation shaft cooperation assembly comprises a U-shaped receiving groove configured to receive the rotation shaft and a damping member matched with the U-shaped receiving groove, wherein the damping member is circular and cross section of the damping member is of inverted U-shape.

2. The underground lamp of claim 1 , wherein the seal ring is made of a rubber material.

3. The underground lamp of claim 1 , wherein the abutment ring is provided with a hollow circular groove circumferentially surrounding the installation port, an orientation of an opening of the circular groove is same as an orientation of the installation port, and the seal ring is disposed in the circular groove.

4. The underground lamp of claim 1 , further comprising a light source assembly, wherein the light source assembly has a light exit surface and a light source assembly side surface circumferentially surrounding the light exit surface, the reflection cup has a light entrance cavity opening opposite to the light exit cavity opening, and the light exit surface is towards the light entrance cavity opening;
the light source assembly has a rotation shaft which protrudes from the light source assembly side surface; and
the installation cavity has a rotation shaft cooperation assembly corresponding to the rotation shaft assembly, and the light source assembly is configured to change an included angle between an optical axis of the light source assembly and the orientation of the installation port through cooperation of the rotation shaft assembly and the rotation shaft cooperation assembly.

5. The underground lamp of claim 4 , wherein an orientation of an opening of the U-shaped receiving groove is towards the installation port, and a depth of the U-shaped receiving groove in the orientation of the installation port is not greater than a diameter of the rotation shaft; and
wherein the damping member covers the rotation shaft in the orientation of the opening of the U-shaped receiving groove and is fixed to the U-shaped groove, and the damping member is configured to provide rotation resistance to the rotation shaft.

6. The underground lamp of claim 4 , further comprising an adjustment rod, wherein the lamp body has an outer peripheral surface circumferentially surrounding the installation port, the installation cavity has an inner peripheral surface, the lamp body further has an adjustment hole penetrating through the outer peripheral surface and the inner peripheral surface, the adjustment hole is coaxial with the rotation shaft, and the adjustment rod penetrates through the adjustment hole and drives the rotation shaft to rotate coaxially with the adjustment rod.

7. The underground lamp of claim 6 , further comprising an adjustment hole waterproof member, wherein a gap is between the adjustment rod and the adjustment hole, and the adjustment hole waterproof member is disposed in the gap and circumferentially fills the gap.

8. The underground lamp of claim 1 , further comprising a pre-embedded member and a fixture member, wherein the pre-embedded member has a pre-embedded cavity, the pre-embedded cavity has a pre-embedded opening, an orientation of the pre-embedded opening is same as the orientation of the installation port, the lamp body is fixed in the pre-embedded cavity, the fixture member is configured to fix the panel to the lamp body and applies to the panel a pressing force towards the installation port, and the fixture member extends in a direction away from the installation port and covers the pre-embedded opening.

9. The underground lamp of claim 8 , wherein the fixture member is a fixture ring, and the fixture ring covers a periphery of the panel.

10. The underground lamp of claim 1 , wherein the abutment step has a bearing ring surface, wherein the bearing ring surface and the installation port inner edge are perpendicular to each other.

11. The underground lamp of claim 3 , wherein cross section of the circular groove is rectangular and cross section of seal ring is circular.
