Downlight apparatus |
| abstract |
A downlight apparatus includes a rotation housing, a spherical housing, a light source and an elastic structure. The rotation housing has a spherical inner surface and a bottom opening. The spherical housing has a spherical outer surface corresponding to the spherical inner surface. The elastic structure presses the spherical housing to engage the rotation housing applying an elastic force to keep the spherical housing to stay at an engaged position with respect to the rotation housing. When an external force is applied to the spherical housing to deform the elastic structure, the spherical housing is escaped from the engaged position and rotatable with respect to the rotation housing until another engaged position is determined by releasing the external force. |
