Abstract
Abstract A lamp assembly includes a central holder attached to and disposed under the ceiling fan and having an electric wire passage, and several circumferentially equidistant illuminating units extending radially from the central holder. Each of the illuminating units includes a tubular connecting rod attached to the central holder, a rotary member connected rotatably to the connecting rod and capable of being locked on the connecting rod, a lamp equipped with an electric plug, and a reflection lamp shield connected removably to the rotary member and positioned over the lamp. The tubular connecting rod has a radial inner end fastened to and extending radially from the central holder, a central bore formed through the connecting rod in communication with the electric wire passage, and a radial outer end. The rotary member has a radial inner end connected rotatably to the radial outer end of the connecting rod, and a radial outer end equipped with an electric socket in which the electric plug is engaged. An electric wire can be passed through the electric wire passage of the central holder and through the central bore of the connecting body to couple with the rotary member.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
180 words
A lamp assembly suspended from a ceiling fan, including a central holder attached to and disposed under said ceiling fan and having an electric wire passage, and several circumferentially equidistant illuminating units extending radially from said central holder, each of said illuminating units comprising: a tubular connecting rod having a radial inner end fastened to and extending radially from said central holder, a central bore formed through said connecting rod in communication with said electric wire passage, and a radial outer end; a rotary member having a radial inner end connected rotatably to said radial outer end of said connecting rod, and a radial outer end equipped with an electric socket; means for locking said rotary member on said connecting rod; a lamp equipped with an electric plug engaged within said electric socket; and a reflection lamp shield connected removably to said rotary member and positioned over said lamp; whereby, an electric wire can be passed through said electric wire passage of said central holder and through said central bore of said connecting body to couple with said rotary member.
Claim 2
Dependent Claim
180 words
A lamp assembly suspended from a ceiling fan, including a central holder attached to and disposed under said ceiling fan and having an electric wire passage, and several circumferentially equidistant illuminating units extending radially from said central holder, each of said illuminating units comprising: a tubular connecting rod having a radial inner end fastened to and extending radially from said central holder, a central bore formed through said connecting rod in communication with said electric wire passage, and a radial outer end; a rotary member having a radial inner end connected rotatably to said radial outer end of said connecting rod, and a radial outer end equipped with an electric socket; means for locking said rotary member on said connecting rod; a lamp equipped with an electric plug engaged within said electric socket; and a reflection lamp shield connected removably to said rotary member and positioned over said lamp; whereby, an electric wire can be passed through said electric wire passage of said central holder and through said central bore of said connecting body to couple with said rotary member.
Claim 3
Dependent Claim
24 words
A lamp assembly as claimed in claim 1, wherein said lamp is an elongated fluorescent lamp, said reflection lamp shield being a rectangular plate.
Claim 4
Dependent Claim
125 words
A lamp assembly as claimed in claim 1, wherein said radial outer end of each of said connecting rods includes two aligned clamping arms which are positioned at the same level, said clamping arms having inner surfaces defining therebetween a hole communicated with said central bore, said inner surfaces of said clamp arms having aligned circular indentions formed therein, said radial inner end of each of said rotary members being round and engaged partially within said indentions of corresponding said clamping arms, so as to clamp tightly said rotary member between said clamping arms of said connecting rod, materials of said connecting rod and said rotary member being selected so as to enable said rotary member to be forced to rotate about said connecting rod.
Claim 5
Dependent Claim
21 words
A lamp assembly as claimed in claim 3, wherein said materials of said connecting rods and said rotary members are copper.
Claim 6
Dependent Claim
87 words
A lamp assembly as claimed in claim 1, wherein each of said rotary member has a dovetail groove formed in an upper surface thereof, and a threaded hole formed in a side wall of said rotary member in communication with said dovetail groove, each of said reflection lamp shields including a dovetail tongue engaged within said dovetail groove of corresponding said rotary member, each of said illuminating units including a locking bolt extending through said threaded hole to lock said reflection lamp shield on said rotary member.
