  • a LED is used, being featured inclusively with a small volume, a low weight, a fast reaction, a long service life, a low attenuation, a strong exterior, an anti-vibration, an easy direction design, a low voltage, a low current, a low conversion loss, a low heat radiation, an easy yield, and an environmental protection on a long thin lamp rack unit 1.
  • Several white-light LEDs 11 are arranged on a circuit and distributed side by side. Said LEDs 11 are arranged in parallel and independent, and their pedestal are adhered with glue or fixed with a plug dowel. Two terminals of the lamp rack unit 1 are changed in different manners of fixing and located by using several securing seats 2 and connection seats 3.
  • a small billboard W or a notice board being projected for illumination may be provided at one end of the lamp rack unit 1 and several latches 13 for the holes are provided at the other terminal.
  • the securing seat 2 may be a flank fixing rack 21 of which one terminal is fixed with screws to two flanks at a rear of the small billboard W and the other terminal is formed with an annular hole 211 corresponding to the hole of said latch 13 for clamping at an angle required.
  • the white-light LEDs 11 are separately distributed in parallel, so that the light source given from the projecting lamp being evenly scattered on the billboard W for evenly distributed rays of light.
  • the white-light LEDs 11 are connected in parallel, and in case that a single lamp is damaged, the rests of lamps are not affected and keep working; thus, only the damaged white-light LED 11 could be replaced, thereby the performance of said projecting lamp unit being increased and low cost of repair being achieved.
  • Several locating holes 12 may be formed at two terminals of the lamp rack unit 1, and several wedge holes 212 are alternatively formed at the other terminal of the flank fixing rack 21 and wedged in a revolving mount 231 of the revolving padlock 23.
  • the revolving padlock 23 is formed in the structure of said securing seat 2 to adjust a revolving plate 232 of the revolving padlock 23 for a required angle of illumination, and thus the locating holes 12 at the two terminals of the lamp rack unit 1 are respectively wedged into the revolving plate 232 with the revolving padlock 23 for location in another manner.
  • Said several locating holes 12 may be formed at the two terminals of the lamp rack unit 1, and several locating holes 213 are alternatively formed at the other terminal of the flank fixing rack 21 and locked with a screw 214 to a terminal of a two-way rack 25.
  • Said two-way rack 25 is formed in the structure of said securing seat 2 at the required angle of illumination, and thus the locating holes 12 at the two terminals of said lamp rack unit 1 are spirally locked to the other terminal of each of the 2 two-way racks 25 respectively, which is another manner for assembly.
  • the securing seat 2 may be in the form of several flank fixing racks 21.
  • a top-and-bottom fixing rack 22 is spirally locked to a rear side of the large billboard W and the other terminal is formed with the annular hole 211 corresponding to the hole of said latch 13.
  • several fixing holes 221 and several lamp rack units 1 are provided and locked at the angle of illumination onto the flank fixing rack 21 and the top-and-bottom fixing rack 22.
  • a middle connection seat 3 may be a middle piece rack 31 provided with several connection holes 311 locked to the opposite terminals of said two lamp rack units 1.
  • Several wedge holes 212 are alternatively formed at the other terminal of the flank fixing rack 21, and the flank fixing rack 21 and the top-and-bottom fixing rack 22 are respectively wedged into the revolving mount 231 of said revolving padlock 23 and a buckle mount 241 of the three-way padlock 24.
  • the revolving padlock 23 and the three-way padlock 24 are formed in the structure of said securing seat 2 to adjust a revolving plate 232 and a buckle plate 242 for the required angle of illumination.
  • the lamp rack unit 1 wedges the locating holes 12 at the two terminals into said revolving plate 232 and the buckle plate 242.
  • the middle connection seats 3 may be the two-way padlocks 32 that may be wedged to the opposite terminals of the two lamp rack unit 1.
  • Several locating holes 213 are alternatively formed at the other terminal of the flank fixing rack 21, and the flank fixing rack 21 and the top-and-bottom fixing rack 22 are respectively locked with screws 214 to lock holes 262 in a rack 261 of a three-way rack 26, lock holes on a base 271 of a T rack 27, lock holes 282 on a base 281 of a four-way rack 28, and lock holes 291 in an upright rack 29.
  • the three-way rack 26, the T rack 27, the four-way rack 28, and the upright rack 29 are formed in the structure of securing seat 2, and the three-way rack 26, the T rack 27, and the four-way rack 28 are formed at the required angle of illumination. So the locating holes 12 at the two terminals of the lamp rack unit 1 are respectively spirally locked onto the lock holes 262 at one terminal of each three-way rack 26, the lock holes 272 at the two opposite terminals of the T rack 27, and the lock holes 282 at an inner terminal of the four-way rack 28.
