Make that three of said LED light fixtures are luminous, light emitting region is 360 degree, the similar fluorescent lamp tube of luminous intensity distribution performance, therefore need not dispose reflector or lens can reach the bigger effect of illuminated area.
Said led light source is along the axially-aligned of said heat-dissipating cylinder.
Further, said led light source is equally distributed on the said substrate, and each substrate is provided with the led light source that quantity equates.
Said heat-dissipating cylinder axis direction straight line, equidistant arrangement can make that said LED lamp luminescence is stable, light intensity is even in said substrate upper edge; Each said substrate is provided with the said led light source of equal amount, makes luminous general effect, intensity unanimity.
Said substrate is thin vertical bar shaped.
Further, the one side of the said heat-dissipating cylinder of said substrate contacts scribbles thermal conductive silicon.
Said led light source is conveniently laid in the design of vertical bar shaped, saves material; Scribble thermal conductive silicon, can accelerate heat radiation, prolong the service life of said LED light fixture.
The Atria of the longitudinal cross-section of a said heat-dissipating cylinder drift angle is a fillet.
Further, each medial surface of said heat-dissipating cylinder is provided with the radiating ribs structure.
Further, said heat-dissipating cylinder is made of aluminum.
Can fix said substrate, confirm the light emission direction of said led light source, guarantee that said LED light fixture 360 degree are luminous, accelerate radiating effect simultaneously.
Further, said lamp tube is that trnaslucent materials is processed.
Can make the LED lamp luminescence evenly, not dazzling.

[specific embodiment]
Below in conjunction with accompanying drawing and specific embodiment, further illustrate.
See also Fig. 1, a kind of LED light fixture 100 comprises: some LED120, some substrates 140, heat-dissipating cylinder 160 and lamp tube 180.Each substrate 140 is provided with led light source 120.Heat-dissipating cylinder 160 longitudinal cross-sections are triangle and have three continuous lateral walls that each lateral wall is provided with substrate 140.In lamp tube 180 is contained in heat-dissipating cylinder 160.
See also Fig. 2, as if the axial equidistant arrangement of led light source 120 along heat-dissipating cylinder 160, and in each substrate 140 first-class quantity setting.In the present embodiment, 9 led light sources 120 are arranged; Per 3 led light sources 120 are along the axial and equidistant setting of heat-dissipating cylinder 160.
See also Fig. 3, each substrate 140 is thin vertical bar shaped, and the one side of contact heat-dissipating cylinder 160 scribbles thermal conductive silicon.Each substrate 140 can be aluminium base, glass fibre substrate etc.Specifically in the present embodiment, 3 substrates 140 are arranged, each substrate 140 is a rectangle, can be aluminium base.
See also Fig. 4, the longitudinal cross-section of heat-dissipating cylinder 160 is roughly triangle, and wherein three drift angles are fillet.In the present embodiment, the longitudinal cross-section of heat-dissipating cylinder 160 is an equilateral triangle, and three drift angles of said equilateral triangle are fillet.In order to improve radiating efficiency, heat-dissipating cylinder 160 is made of aluminum.Simultaneously, in order further to accelerate radiating effect, the madial wall of heat-dissipating cylinder 160 is provided with the radiating ribs structure.
