The specific embodiment

In such as refrigerator lighting some situation of (wherein needing larger light output angle), the embodiment of rotary end cap allows the light source with directionality output angle to be used.With reference now to Fig. 1,, the present embodiment relates to the LED lamp 100 that promotes utilization to comprise LED pipe 101 and substitutes traditional fluorescent lamp.Rotary end cap 102 provides on each end of lamp, to allow terminal use to regulate the light output angle of LED pipe 101 by rotation body, be maintained to the electrical connection (only a rotary end cap is shown in Figure 1) of light fixture (light fixture) simultaneously.In addition, rotary end cap 102 can be with specific output angle locking, for preventing the position/output angle of LED pipe 101 rotations through expecting.LED pipe 101 can comprise solid state light emitter, such as, but be not limited to multiple LED.In certain embodiments, solid state light emitter can comprise directional light.

Fig. 2,2A, 2B and 2C show the embodiment of rotary end cap 200.Rotary end cap 200 comprises Part I 201, and it is connected to Part II 202 rotatably around central opening 204.Part II 202 is configured to connect LED pipe, and such as LED pipe 101, and Part I 201 is configured to electrically connect via electric connector 203 electric connector of light fixture.Each electric connector 203 can be connected to wire 214.Wire 214 can be electrically coupled to LED and manage 101 relevant electronic devices.Each wire 214 can send through central opening 204, manages 101 relevant electronic devices electric connector 203 is connected to LED.Wire 214 can comprise multiply Metal Substrate wire, and it can withstand the rotation of rotary end cap 200 better.But in certain embodiments, wire can comprise single cord.

Part I 201 also comprises central opening 204, for example, to receive the tab 206 (, tab 206 is configurable through central opening 204) being positioned on Part II 202.Central opening 204 can be cylindrical openings, and it is shaped as and promotes that tab 206 rotates around central opening.But the opening of other shapes also can be used.Part I 201 also comprises the open-topped flat surface 211 of external central opening 204.Flat surface 211 can comprise stop block 210, for preventing that rotary end cap 200 from rotating.This can for example, provide advantage by preventing the unexpected region (, the inside of refrigerator) of light illumination target.Each tab 206 can comprise locking tab 207, Part I 201 be fixed to Part II 202 and prevent that Part I 201 is pulled away from from Part II 202.Locking tab 207 can be perpendicular to tab 206.In certain embodiments, corresponding tab 206 and locking tab 207 can form tab element, and it comprises vertical arm (for example, tab 206) and lock portion (for example, locking tab 207).

Part I 201 also comprises multiple teeth 205, for example, to connect removedly the multiple recesses 208 (conduit) that are positioned on Part II 202.Each in tooth 205 can for example, be connected to Part I 201 via corresponding flexible shaft 212 (flexible), thereby allows tooth 205 bendings to enter and leave multiple recesses 208 (for example tooth is flexible).Multiple recesses 208 can be positioned on the flat surface 213 of Part II 202.Flat surface 213 can be perpendicular to sidepiece 209.

In use, make tab 206 bendings to allow locking tab 207 through centre gangway 204 by tab 206 being inserted through central opening 204, Part I 201 can be connected to Part II 202.Once locking tab 207 is through central opening 204, tab 206 will be returned in bending, makes to lock tab 207 and prevents that tab 206 is pulled through central opening 204.In addition, when in use, multiple teeth 205 can respectively engage the recess in multiple recesses 208, so that Part I 201 is locked in Part II 202.For Part I 201 is rotated, revolving force can be applied to Part I 201, to cause multiple teeth 205 to be bent upwards and to depart from corresponding recess, thereby cause Part I 201 to rotate, until multiple tooth 205 engages other corresponding recess 208 (for example multiple teeth can be flexible).

In one embodiment, tab 206 can comprise two tabs, each tab 206 distances 180 degree each other.Stop block 210 can be placed to and prevent that rotary end cap 200 rotations from exceeding 180 degree.In the time rotating, stop block 210 can engage locking tab 207, thereby prevents that Part I 201 from continuing rotation.This can for example, provide advantage by preventing light illumination from arriving the unexpected region of target (, the inside of refrigerator).For example, by preventing that end cap 200 rotations from exceeding 180 degree, light source is by the illumination region that roughly can't throw light on light source in the region under light source.

Part I 201 and Part II 202 can be made up of plastics, such as, but be not limited to Merlon or ABS.But each electric connector 203 can comprise conductive material, such as metal.

With reference now to Fig. 3,3A and 3B,, show the embodiment of rotary end cap 300.Rotary end cap 300 comprises the Part I 301 that is connected to rotatably Part II 302.

Part I 301 comprises electric connector 303, and it is configured to rotary end cap 300 to be electrically coupled to light fixture (not shown).Part I 301 also comprises tab 305, and wherein each tab 305 comprises locking tab 306, Part I 301 be fixed in Part II 302 and prevent that Part I 301 from separating from Part II 302.Locking tab 306 can be directed or be positioned to perpendicular to tab 305.Part I 301 also comprises first group of multiple tooth 304 (for example, sawtooth), for example, to engage the second group of multiple tooth 309 (, sawtooth) that are positioned on Part II 302.Second group of multiple tooth 309 is positioned on the sidewall at top 307 of Part II 302.Second group of multiple tooth 309 limits multiple recesses, and it is positioned between each in second group of multiple tooth.Each corresponding recess can be close to corresponding in second group of multiple tooth 309.Multiple recesses are received first group of multiple tooth 304.Top 307 comprises the diameter less than bottom 310.Top 307 is connected to the top surface of bottom 310.Part II 302 also comprises central opening 308, to receive tab 305.Central opening 308 extends through top 307 and bottom 310.

Part II 302 can also comprise flat surface 311, the central opening 308 of its external Part II 302.Flat surface 311 can comprise stop block, for preventing the angle of rotary end cap 300 rotations through expecting.

In use, make tab 305 bendings to allow locking tab 306 through central opening 308 by tab 305 being inserted through central opening 308, Part I 301 is rotatably connected to Part II 302.Tab 305 flexible return, make to lock tab 306 and prevent that tab 305 is back pulled through central opening 308, and Part I 301 can rotate around tab 305.In addition, when in use, first group of multiple tooth 304 can respectively engage the recess being limited by second group of multiple tooth 309, so that Part I 301 is locked in Part II 302.For Part I 301 is rotated, revolving force can be applied to Part I 301.Revolving force can cause first group of multiple tooth 304 on second group of multiple tooth 309, to oppress (for example, bending).For example, once compressing (, bending) on second group of multiple tooth 309, first group of multiple tooth 304 can rely in corresponding recess, to cause Part I 301 to stop rotation, unless applied suitable revolving force.Each in first group of multiple tooth 304 is shaped as and makes first group of multiple tooth 304 can be on second group of multiple tooth 309 bending.First and second groups of multiple teeth 304/309 can comprise flexiplast, such as, but be not limited to flexible polymer or elastomer.

The present embodiment also relates to the method that Part I is attached to Part II.For example, with reference to figure 2,2A, 2B and 2C, the tab 206 of Part II 202 can be inserted in the central opening of Part I 201.For Fig. 3,3A and 3B, the tab 305 of Part I 301 can be inserted in the central opening of Part II 302.

In addition, for example, once tab is inserted through central opening (, central opening 308), tab can be bending in a first direction, for example, to allow locking tab (, locking tab 306) through central opening.Once locking tab has passed central opening, the flexible home position of getting back to them of tab, makes to lock tab and prevents that tab is back pulled through central opening.

Although the present invention describes in conjunction with concrete one exemplary embodiment, but be to be understood that, can disclosed embodiment be made apparent various change for those skilled in the art, substitutes or be substituted, and not depart from the spirit and scope of the present invention that claims are stated.
