The operation of the module allows the LEDs to remain illuminated. Moreover, after the power converter of one of the light-emitting diode modules of the light-emitting diode lamp is damaged, it is not necessary to be rushed to repair, but can wait for the power converter of the plurality of light-emitting diode modules to be repaired together after being damaged. Thereby reducing the maintenance cost of the luminaire.

請一併參閱圖9-10，固持件30還可包括一托夾34。該托夾34可配合固持件30的定位夾32使用，也可以單獨使用(即固持件30僅包括托夾34)。托夾34包括一固定板340及分別從固定板340的相對兩側向下延伸的二托臂342。固定板340上開設有二螺孔341，用於供螺絲穿設而將固定板340鎖固於燈體20的容腔200內。固定板340的寬度大於連接板320的寬度，托臂342的長度大於彈性臂322的長度。每一托臂342的頂部朝內傾斜延伸然後再向上延伸而與固定板340連接，托臂342的底部也向內彎折而形成一V形的卡接部344。當托夾34單獨使用時，該卡接部344可與燈殼42的立柱428的卡槽429配合而將燈殼42夾持於燈體20上。當托夾34配合定位夾32使用時，定位夾32收容於托夾34內，定位夾32的連接板320置於托夾34的固定板340上，定位夾32的二彈性臂322與托夾34的二托臂342平行且被托夾34的二托臂342夾設。定位夾32的二彈性臂322的卡接部324卡入立柱428的二卡槽429內，以將立柱428卡接於固持件30上。同時，托夾34的二托臂342的內側面抵接立柱428的相對二側面，托夾34的二托臂342的卡接部344抵接於立柱428的相對二側面的底部，從而進一步托住立柱428，使其更可靠地安裝於燈體20上。更進一步地，立柱428還可在其相對二側面的底部也分別形成二V形的卡槽429，由此，托夾34的二托臂342的卡接部344可進一步卡設於立柱428二側面底部的卡槽429內，從而與定位夾32一同固定燈殼42。由於是通過固持件30卡接的方式將燈殼42固定於燈體20上，因此發光二極體模組40的組裝及 拆卸過程較為便利，可有效節省人力及物力。 Referring to FIGS. 9-10 together, the holder 30 can also include a bracket 34. The carrier clip 34 can be used with the positioning clip 32 of the holder 30 or can be used alone (ie, the holder 30 includes only the carrier clip 34). The bracket 34 includes a fixing plate 340 and two bracket arms 342 extending downward from opposite sides of the fixing plate 340, respectively. Two fixing holes 341 are defined in the fixing plate 340 for screwing the fixing plate 340 into the cavity 200 of the lamp body 20. The width of the fixing plate 340 is larger than the width of the connecting plate 320, and the length of the supporting arm 342 is larger than the length of the elastic arm 322. The top of each of the support arms 342 extends obliquely inwardly and then extends upward to be coupled to the fixed plate 340. The bottom of the support arm 342 is also bent inwardly to form a V-shaped snap portion 344. When the bracket 34 is used alone, the engaging portion 344 can cooperate with the slot 429 of the post 428 of the lamp housing 42 to clamp the lamp housing 42 to the lamp body 20. When the clip 34 is used with the positioning clip 32, the positioning clip 32 is received in the bracket 34, and the connecting plate 320 of the positioning clip 32 is placed on the fixing plate 340 of the bracket 34, and the two elastic arms 322 and the clip of the positioning clip 32 are disposed. The two carrier arms 342 of 34 are parallel and are sandwiched by the two carrier arms 342 of the carrier 34. The engaging portion 324 of the two elastic arms 322 of the positioning clip 32 is engaged in the two slots 429 of the post 428 to engage the post 428 on the holding member 30. At the same time, the inner side surfaces of the two bracket arms 342 of the bracket 34 abut against the opposite sides of the column 428, and the engaging portions 344 of the two bracket arms 342 of the bracket 34 abut against the bottoms of the opposite sides of the column 428, thereby further supporting The column 428 is housed to be more reliably mounted on the lamp body 20. Further, the pillar 428 can also form a two-shaped card slot 429 at the bottom of the opposite sides thereof, whereby the engaging portion 344 of the two bracket arms 342 of the bracket 34 can be further engaged with the column 428. The card slot 429 is formed at the bottom of the side to fix the lamp housing 42 together with the positioning clip 32. Since the lamp housing 42 is fixed to the lamp body 20 by the manner in which the holding member 30 is engaged, the assembly of the LED module 40 and The disassembly process is convenient and can save manpower and material resources.
請一併參閱圖11-12，固持件30還可進一步包括一限位板36。限位板36包括一安裝板360及一從安裝板360一側垂直延伸的托板362。安裝板360上開設有二螺孔361，托板362的末端向外傾斜彎折。安裝板360的寬度小於連接板320的寬度，托板362的長度小於彈性臂322的長度。當限位板36與定位夾32及托夾34共同使用時，托夾34的固定板340、定位夾32的連接板320及限位板36的安裝板360先後依次疊設於燈體20的容腔200內，螺絲依次穿過安裝板360、連接板320及固定板340的螺孔361、321、341而鎖固於燈體20上，從而將限位板36、定位夾32及托夾34固定於燈體20上。同時，定位夾32的二彈性臂322與托夾34的二托臂342平行且置於二托臂342的內側，限位板36的托板362垂直於定位夾32的二彈性臂322且與定位夾32的二彈性臂322及托夾34的二托臂342錯開。立柱428的卡槽429被定位夾32的二卡接部324卡入，相對二側面被夾持於托夾34的二托臂342之間，另一側面被限位板36的托板362所托住。由此，立柱428被固持件30從三個方向限位。特別地，集成有限位板36的固持件30可用於對如圖13所示的諸如運動場照明燈具10a的發光二極體模組40進行固定，因為此種照明燈具中的發光二極體模組40是傾斜水準放置，因此需要限位板36從下方托住立柱428。另外，如圖14所示的隧道燈10b、如圖15所示的公路橋欄杆燈10c以及其他類型的照明燈具也同樣可使用此種固持件30對其發光二極體模組40進行固定。由於照明角度不同，因此不同的照明燈具可根據實際需求選擇固持件30中的單個元件(如定位夾32)、兩個元件(如定位夾32及托夾34)或者是三個元件都使用。並且，不同照明燈具的固持件30的使用數量也根據發光 二極體模組40的數量有所區別。比如，運動場照明燈具10a由於要求照明較大的範圍，需要使用較多數量的發光二極體模組40。因此，運動場照明燈具10a在其矩形的燈體20a內對應七個發光二極體模組40設有十四個固持件30。隧道燈10b則由於照明範圍相對較小，因此需要在其矩形的燈體20b內設置十個固持件30以固定五個發光二極體模組40。公路橋欄杆燈10c的照明範圍最小，因此僅需要在其矩形的燈體20c內設置四個固持件30即可固定其二發光二極體模組40。此外，固持件30的定位夾32、托夾34及限位板36也可一體製造形成，而不需如前述所揭示的各自分別製造。 Referring to FIGS. 11-12 together, the holder 30 may further include a limiting plate 36. The limiting plate 36 includes a mounting plate 360 and a bracket 362 extending perpendicularly from a side of the mounting plate 360. Two mounting holes 361 are defined in the mounting plate 360, and the ends of the supporting plates 362 are bent outwardly. The width of the mounting plate 360 is smaller than the width of the connecting plate 320, and the length of the supporting plate 362 is smaller than the length of the elastic arm 322. When the limiting plate 36 is used together with the positioning clip 32 and the bracket 34, the fixing plate 340 of the bracket 34, the connecting plate 320 of the positioning clip 32, and the mounting plate 360 of the limiting plate 36 are sequentially stacked on the lamp body 20. In the cavity 200, the screws are sequentially locked to the lamp body 20 through the screw holes 361, 321, 341 of the mounting plate 360, the connecting plate 320 and the fixing plate 340, thereby the limiting plate 36, the positioning clip 32 and the clip. 34 is fixed to the lamp body 20. At the same time, the two elastic arms 322 of the positioning clip 32 are parallel to the two bracket arms 342 of the bracket 34 and are disposed inside the two bracket arms 342. The bracket 362 of the limiting plate 36 is perpendicular to the two elastic arms 322 of the positioning clip 32 and The two spring arms 322 of the positioning clip 32 and the two carrier arms 342 of the carrier clip 34 are offset. The slot 429 of the post 428 is engaged by the two latching portions 324 of the positioning clip 32, the opposite sides are clamped between the two bracket arms 342 of the bracket 34, and the other side is supported by the bracket 362 of the limiting plate 36. Hold on. Thus, the post 428 is restrained by the retaining member 30 from three directions. In particular, the holder 30 of the integrated limiting plate 36 can be used to fix the LED module 40 such as the stadium lighting fixture 10a as shown in FIG. 13 because of the LED module in the lighting fixture. 40 is placed at an inclined level, so the limit plate 36 is required to hold the post 428 from below. In addition, the tunnel lamp 10b shown in FIG. 14, the road bridge railing lamp 10c shown in FIG. 15, and other types of lighting fixtures can also be used to fix the LED module 40 using the holder 30. Due to different illumination angles, different lighting fixtures can select individual components (such as positioning clips 32), two components (such as positioning clips 32 and carrier clips 34) in the holder 30, or all three components, depending on actual needs. Moreover, the number of holding members 30 of different lighting fixtures is also based on the amount of light The number of diode modules 40 is different. For example, the stadium lighting fixture 10a requires a larger number of LED modules 40 due to the larger range of illumination requirements. Therefore, the stadium lighting fixture 10a is provided with fourteen holding members 30 corresponding to the seven LED modules 40 in its rectangular lamp body 20a. Since the tunnel light 10b has a relatively small illumination range, it is necessary to provide ten holding members 30 in the rectangular lamp body 20b to fix the five light-emitting diode modules 40. The road bridge railing light 10c has the smallest illumination range. Therefore, it is only necessary to provide four holding members 30 in the rectangular lamp body 20c to fix the two light-emitting diode modules 40. In addition, the positioning clip 32, the bracket 34 and the limiting plate 36 of the holding member 30 can also be integrally formed without separately manufacturing as disclosed above.
請一併參閱圖16，燈體20內還進一步集成有電網電源分線盒50，以為各發光二極體模組40供電。電網電源分線盒50的輸入端包括一火線52、一零線54及一地線56。零線54為標準點，由火線52輸入的隨時間變化的正負電壓與零線54產生電位差而形成交流電。地線56接於燈體20上，以防止觸電。電網電源分線盒50的內部設有一防雷裝置58，其包含有諸如壓敏電阻之類的防雷電器件。防雷裝置58對應發光二極體模組40的數量在其輸出端拉出多根火線52及零線54，使每一發光二極體模組40的電源轉換器44均與一根火線52及一根零線54連接。由此，發光二極體燈具10通過電網電源分線盒50給每一發光二極體模組40供電。 Referring to FIG. 16 together, the power grid distribution box 50 is further integrated in the lamp body 20 to supply power to each of the LED modules 40. The input end of the grid power distribution box 50 includes a fire line 52, a zero line 54 and a ground line 56. The neutral line 54 is a standard point, and the time-varying positive and negative voltage input by the hot line 52 generates a potential difference from the neutral line 54 to form an alternating current. The ground wire 56 is connected to the lamp body 20 to prevent electric shock. A lightning protection device 58 is provided inside the grid power distribution box 50, which includes an anti-lightning device such as a varistor. The lightning protection device 58 corresponding to the number of the LED modules 40 pulls a plurality of fire wires 52 and neutral wires 54 at the output end thereof, so that the power converters 44 of each of the light-emitting diode modules 40 are connected to a fire wire 52. And a zero line 54 connection. Thus, the light-emitting diode lamp 10 supplies power to each of the light-emitting diode modules 40 through the grid power distribution box 50.
由於各發光二極體模組40的電源轉換器44均是獨立工作的，因此即使一個發光二極體模組40的電源轉換器44損壞，也不會影響到其他發光二極體模組40的正常工作，從而使發光二極體燈具10仍能保持發光。並且，可以等到多個發光二極體模組40均損壞時再 同時對這些發光二極體模組40進行維修或更換工作，而不必在每個發光二極體模組40一損壞時就進行維修或更換，從而節省維修成本。 Since the power converters 44 of the LED modules 40 are all independent, even if the power converter 44 of one LED module 40 is damaged, it will not affect other LED modules 40. The normal operation of the light-emitting diode lamp 10 can still keep the light. Moreover, it is possible to wait until the plurality of light emitting diode modules 40 are damaged. At the same time, the LED modules 40 are repaired or replaced without repair or replacement when each of the LED modules 40 is damaged, thereby saving maintenance costs.
可以理解地，除上述揭露的發光二極體路燈10、運動場照明燈具10a、隧道燈10b及公路橋欄杆燈10c之外，本發明的發光二極體模組40同樣適用於其他各種類型的照明燈具，比如庭院燈、天井燈、廣場燈、走廊燈等等。 It can be understood that the light-emitting diode module 40 of the present invention is applicable to other various types of illumination, in addition to the above-described light-emitting diode street lamp 10, the stadium illumination lamp 10a, the tunnel lamp 10b, and the road bridge railing lamp 10c.
