Further, the LED lamps 2 and the conductor sections 3 tend to be stuck within the sleeve 1 during the manufacturing process. This is particularly true when the sleeve 1 has a length longer than a predetermined one, resulting in an interrupt of the manufacturing process. In a less serious case, a distance between two adjacent LED lamps 2 may be different from that of another two adjacent LED lamps 2. And in turn, the already bent conductor section 3 is further bent or extended. As an end, a desired configuration of equal spaced apart LED lamps 2 is not obtainable. Consequently, a uniform light emitted from the light device is made impossible.
  • LED lamps 2 tend to displace slightly in the sleeve 1, i.e., not reliably secured. As such, light emitted from a displaced LED lamp 2 may not concentrate in a direction parallel to, for example, X-Z plane, i.e., being oblique relative to the X-Z plane.
