It is solved in view of the above problems, being badly in need of us.

Utility model content

The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of increase light emitting angle, improve illumination Intensity, and good heat dissipation effect, the LED improved service life draw taillight.

In order to achieve the above object, a kind of LED drawing taillight designed by the utility model, it includes drawing rear light cover, route Plate, lamp holder, light-guiding pillar and LED lamp bead, lamp holder by including that lamppost and cooling fin are constituted, lamppost lateral wall from bottom to up and to Being extended with multiple length outside is 4~5cm, the cooling fin with a thickness of 0.2~0.4cm, the two-by-two spacing between adjacent cooling fin Upper end for 0.5cm, and cooling fin adjacent two-by-two is linked into an integrated entity by arc-like sheet, and the top position of cooling fin is higher than arc The top position of piece, so that the lamp holder obtained after connecting by lamppost, cooling fin with arc-like sheet is made to be in " loudspeaker " shape structure, The outer surface of lamp holder lower end is additionally provided with connection external screw thread；It is equipped with wiring board at the top of lamp holder, wiring board is equipped with LED lamp Pearl, wiring board are connect with LED lamp bead by conducting wire, and light-guiding pillar is coated on the outside of LED lamp bead, and light-guiding pillar is in hollow Mitsubishi Wimble structure so that the light for issuing LED lamp bead is distributed on three faces of light-guiding pillar, and is distributed light by light-guiding pillar； It draws the connection type of the mode or buckle that are connected through a screw thread between the bottom of rear light cover and the top of lamp holder to link into an integrated entity, draws Rear light cover is constituted using transparent material, and drawing rear light cover is that the edge of a hollow annulus has upwardly extended side wall, draws taillight The upper end of cover is to contract and intersects at a bit, and drawing the upper end of rear light cover is in warp architecture, to form a drawing tail effect.

It is attached for convenience with extraneous control power supply, outer connecting line is connected on wiring board, and outer connecting line prolongs Extend to the outside of lamp holder.

According to the above, a kind of LED drawing taillight, is designed by the unique structure, is made designed by the utility model Obtaining the light that LED lamp bead irradiates can be emitted under the reflex of light-guiding pillar to three different directions, not only be increased Light emitting angle also improves the intensity of illumination in illumination space；And due to the design of lamp holder, so that heat dissipation effect enhances, significantly Improve service life.Therefore, it has the characteristics that simple structure and reasonable design and easy to use.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model.

Specific embodiment
