Said structure eliminates the light-conductive optic fibre of traditional cold light source, reduces the intrinsic volume of cold light source, simplifies design,
Due to eliminating light-conductive optic fibre, large angle illumination can be realized and light extraction efficiency is effectively improved, so as to improve the use longevity of product
Life, makes the reliability of product more secure.
Further, light source fixing part 2 includes Handheld Division 21 and straight-bar 22, and one end and the Handheld Division 21 of straight-bar 22 are fixed,
PCB pinboards 4 are fixed on the end face of the other end of straight-bar 22, and PCB lamp board 3 is located at the front of PCB pinboards 4, and LED lamp bead
5 are fixed in the PCB lamp board 3.Straight-bar 22 is designed as an elongate rod, and overall structure causes that LED lamp bead 5 is in lead position.
The utility model also includes protection cap 6, and the protection cap is matched with the other end of straight-bar 22, when not in use, protection
Between the other end connection of lid 6 and straight-bar 22 is to form receiving so that LED circuit board and LED lamp bead 5 are interior positioned at the receiving, from
And enter to play a part of dust-proof, protection to LED circuit board and LED lamp bead 5.
It will be apparent to those skilled in the art that technical scheme that can be as described above and design, make other various
