Now in detail the preferred embodiment being used for the rotating end cap of the LED lamp tube of replacing fluorescent tube will be described.
electricity aspect
Start from the inside and the end that goes directly, LED track/fin 68 (Fig. 2) provides LED to dismantle groove 72 (Fig. 7 c), and it is supported for tubular lamp bulb 10 and provides the LED array band of illumination and provide heat radiation for it.Be LED controller PCB76 in the one or both ends of LED track/fin 68, when fluorescent tube 10 rotates to the position shown in Fig. 8 b, it is changed and regulates by end-cap assembly 12 from lamp socket 82 (Fig. 8 a/8b), the power supplied from pin terminals 34.When end cap 14 be rotated into make terminal 34 and conductive base pin catch part 86 engage time, the lamp socket protuberance 28 of contact bolt 26 is locked between pin guiding piece 84.Rotation causes contact cam 30 to make each group termination contact part 36 and often organize PCB contact 38 and be connected, and it provides power (attention, each PCB contact 38 protuberance is as shown in the figure 6c directly electrically connected to adjacent PCB76) to PCB76.Substantially, when fluorescent tube 10 inserts (in the fixture that Fig. 8 a) uses two Lamp socket with pins 82 and by when rotating shown in Fig. 8 b, if lamp socket 82 is energized, fluorescent tube 10 can be powered by user.
mechanical aspects
For providing the ability of the incidence angle of progressive adjustment fluorescent tube 10 to user, device end cap 14 being locked onto enable rotating light tube 78 and LED track/fin 68 simultaneously in lamp socket 82 must be provided.By means of clamp segment 46, (Fig. 4 a) remains in the deflection gear 56 (Fig. 7 b) of rotatable housing 54 deflection ring 40.Deflection ring 40 bends along with its deflection section 48 and can progressively rotate, and deflection tooth 50 can be advanced regularly around deflection gear 56.Because LED only projects the light from its substrate side, when the housing backstop 52 on ring 40 meets with the arbitrary ring backstop 58 shown in Fig. 1 or 7b, prevent from exceeding the rotation of 180 degree.By these means, deflection ring 40 and the remainder of end-cap assembly 12 make user can rotating light tube 78 (usually by means of each housing to avoid fluorescent tube of making dirty), and the pin terminals of fluorescent tube 10 can not be made to throw off.Substantially, each end-cap assembly 12 is locked in each lamp socket 82, and simultaneously each housing 54 and the fluorescent tube 78 that is associated thereof can by means of the progressive rotations of deflection ring 40.
Contact bolt 26 is the device that can carry out electrical contact by means of it in each end-cap assembly 12.Within it rotate freely in the axle bed 44 (Fig. 1 and 6c) that the annulate shaft 32 (Fig. 5 b) of contact bolt 26 is inserted into deflection ring 40.Fig. 6 b is the reverse side of the element shown in Fig. 8 a, and wherein lamp socket protuberance 28 aligns with pin terminals 34, does not carry out any contact.Fig. 8 b shows the lamp socket protuberance 28 be fixed between pin guiding piece 84, and make by rotating end cap 14 (thus rotating deflection ring 40), two groups of contacts (36-38) force together by contact cam 30.By these means, rotating end cap assembly 12 engages the electrical contact between pin terminals 34 and PCB76, still allows by means of the deflection progressive rotary shell 54 of ring 40 and fluorescent tube 78 simultaneously.
other aspect
As illustrated in 8 a and 8b, once end cap 14 engages, its deflection groove 24 can use the particular delta of the incidence angle selected up to about 180 degree together with the transposition groove 60 on housing 54, perpendicular to each 90 degree of every side of the axle of LED track 68.Thus user can regulate fluorescent tube 78 to select required specific illumination direction by means of arbitrary housing 54.
As shown in figs. 1 and 2, end-cap assembly 12 is fixed together by means of end cap securing member 18, and end cap 14 is fixed to the corresponding end cover fastener seat 42 on deflection ring 40 through fastener hole 16 by it.When fixing, all the other elements of end-cap assembly 12 are remained in end cap 14 by deflection ring 40.As mentioned above, assembly 12 be snapped to housing 54 deflection gear 56 in and fix by means of clamp segment 46 and deflection section 48.As shown in Figure 7 a, track fastener support 62 is embedded in the bottom of rotatable housing 54 to provide the device be fixed on by LED track/fin 68 in fluorescent tube 78.The end that Fig. 7 c shows track securing member 66 (stay bolt) is inserted through guide fasteners part 64 (Fig. 7 b), and is screwed in the securing member folder 70 in the bottom of LED track/fin 68.What the alternative of Fig. 7 b showed guide fasteners part 64 analyses and observe details.By these means, track securing member 66 fastens every one end of LED track/fin 68 support member 62 of the bottom place of each housing 54 and the length direction of each fluorescent tube 78 with a bolt or latch.
Use description to now the preferred material constructing rotatable LED fluorescent tube.Terminal and contact are made by conducting electricity non-corrosive metal.LED track/fin is by the aluminium extruded or can support LED array and the equivalent metal of enable enough heat-sinking capabilities is formed.Except PCB and may be made up of that extrude or molded Merlon or plastic materials by the every other element except securing member, there is enough intensity and mechanical elasticity reliably to run.Securing member may be made of metal.According to user's requirement, fluorescent tube can be transparent or semitransparent.Do not get rid of other materials, if these materials provide similar or the ability of improvement.
Illustrative description should be only considered as above to the description of preferred embodiment and installation method, and nonrestrictive description.Such as, the fluorescent tube with the luminaire being different from LED can use the present invention to cause it rotatable.For similar results can adopt other forming techniques and other materials.When not deviating from true scope of the present invention, those skilled in the art can carry out multiple different change and amendment.
