Abstract

A swing lamp includes a housing and a light-emitting device mounted in the housing. The housing is so structured that it may swing like a tumbler when it is pushed or touched. The light-emitting device includes a flexible lamp holder, and a plurality of light-emitting diodes mounted on a top of the flexible lamp holder and powered by a power supply to emit light toward a translucent upper part of the housing in different directions. When the housing is pushed to swing, the flexible lamp holder in the housing sways at the same time, causing the light emitted from the light-emitting diodes to produce irregularly changeful light and shade at different positions on the housing and thereby enabling the swing lamp to provide a dynamic ornamental effect.

Claims

1. A swing lamp adapted to show flickering light and shade, comprising a housing and at least one light-emitting device mounted in said housing;

said housing including a lower housing and a translucent upper housing, and having an overall shape enabling said housing to swing like a tumbler when said housing is pushed or touched; and

said light-emitting device including a flexible lamp holder, a plurality of light-emitting diodes mounted to a top of said flexible lamp holder, a power supply for supplying power to said light-emitting diodes for the latter to emit light, and an operating button;

said flexible lamp holder including a swing seat, and an elastic element fixedly connected at an upper end to a bottom of said swing seat and at a lower end to an inner side of said lower housing, such that said swing seat may sway in said housing when said elastic element is flexibly moved; and

said operating button having an end projected from a lower part of said lower housing for a user to control on/off of said light-emitting diodes and/or illuminating patterns;

whereby when said swing lamp is pushed or touched at said housing to swing to and fro in different directions, said swing seat of said light-emitting device irregularly sways in said housing at the same time, causing light emitted from said light-emitting diodes on said swing seat to produce irregularly changeful and flickering light and shade on said translucent upper housing.

2. The swing lamp adapted to show flickering light and shade as claimed in claim 1, wherein said lower housing includes a semispherical bottom, and a weight fixed to an inner bottom center of said lower housing, so that a center of gravity of said whole swing lamp falls at said inner bottom center of said lower housing to enable said swing lamp to swing like a tumbler.

3. The swing lamp adapted to show flickering light and shade as claimed in claim 1, wherein said lower housing is connected at a bottom to a top of an elastic element, and said elastic element being connected at a lower end to a supporting base, whereby said housing of said swing lamp may swing like a tumbler above said elastic element and said supporting base when said housing is pushed or touched.

4. The swing lamp adapted to show flickering light and shade as claimed in claim 1, wherein said flexible lamp holder is uprightly connected to an inner bottom center of said lower housing.

5. The swing lamp adapted to show flickering light and shade as claimed in claim 1, wherein said light-emitting diodes emit different color light.

6. The swing lamp adapted to show flickering light and shade as claimed in claim 1, wherein said light-emitting diodes emit light in different directions to produce said light and shade at different positions on said upper housing.
