Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
119 words
An improved body-electrostatic induction type of lamp device mainly comprising: a non-metal lamp stand being mounted with a nonmetal lamp shade, a lamp socket, a metal tube, a touch switch, a lamp, and a metal fixture; and said metal tube and said touch switch being mounted in the hollow cavity of said non-metal lamp stand by means of nuts; and said metal fixture mounted on said metal tube but on the top of said non-metal lamp stand being used for mounting a metal support frame; and on said metal support frame, said lamp shade being mounted; and both the non-metal portions of said lamp stand and said lamp shade having body-electrostatic induction function upon being contacted by a person.
Claim 2
Dependent Claim
119 words
An improved body-electrostatic induction type of lamp device mainly comprising: a non-metal lamp stand being mounted with a nonmetal lamp shade, a lamp socket, a metal tube, a touch switch, a lamp, and a metal fixture; and said metal tube and said touch switch being mounted in the hollow cavity of said non-metal lamp stand by means of nuts; and said metal fixture mounted on said metal tube but on the top of said non-metal lamp stand being used for mounting a metal support frame; and on said metal support frame, said lamp shade being mounted; and both the non-metal portions of said lamp stand and said lamp shade having body-electrostatic induction function upon being contacted by a person.
Claim 3
Dependent Claim
78 words
A lamp devise as claimed in claim 1, wherein the lamp stand is a hollow member made of non-metal material such as ceramic, porcelain, wood, clay, plaster, stone, or plastics; and wherein said touch switch includes a portion of an operation circuit; and when said lamp stand or said lamp shade being contacted by a person, a signal being generated as a result of the body static charge, and then said signal being coupled into said touch switch.
Claim 4
Dependent Claim
50 words
A lamp device as claimed in claim 1, wherein the surface of said non-metal lamp shade includes a conductive fiber net being sewed or adhered thereon; and said conductive fiber net being electrically connected with said touch switch through a conductive means so as to obtain a contact induction effect.
Claim 5
Dependent Claim
81 words
A lamp device as claimed in claim 1, wherein said lamp shade includes a plurality of frame members being assembled into a frame on a detachable basis; and said frame mainly including an upper ring having three arcshaped wires, a lower ring having three arc-shaped wires, three reverse L-shaped members, a ring fixture, and six T-shaped connectors, whereby said lamp shade can be assembled and disassembled so as to reduce the dimensions of said lamp shade when shipping or in storage.
