Description of drawings
Fig. 1 is the sectional side elevation of a kind of LED electricity-saving lamp of the utility model structure.
Fig. 2 is the cutaway view of Fig. 1 along the A-A line.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment.
As depicted in figs. 1 and 2, this practical New LED electricity-saving lamp comprises the upper casing 4 that is connected with lamp holder 1, the lampshade 19 that is threaded with upper casing, and wick and circuit board constitute, and are integrated with a plurality of LED on the circuit board.Wick is positioned at lampshade, and described upper casing 4 is formed by upper half shell 5 and following 7 two parts fit, and its inner chamber can be put into a driver.
Described wick adopts the aluminium matter stem stem 13 of tubulose, the bottom outlet of being opened on 4 times seats 7 of its end and upper casing joins for 9 mouthfuls, described circuit board has transverse circuit plate 16 and some strip circuit plates 10 to constitute, and transverse circuit plate 16 and strip circuit plate 10 lay the aluminium base 17 of copper foil circuit and aluminium base 11 with having its surface insulation respectively; Be evenly equipped with the convex tendon 21 consistent that extends vertically on described aluminium matter stem stem 13 peripheries with strip circuit plate 10 quantity, the head thickness of this convex tendon is thicker than its root, for example "T"-shaped shape, with the corresponding position, convex tendon 21 position of aluminium matter stem stem 13 groove 22 that cooperates with described convex tendon 21 is arranged on aluminium base 11 back side of arbitrary strip circuit plate 10, groove 22 sleeves on the described strip circuit plate 10 are outside the convex tendon 21 of aluminium matter stem stem 13, form all strip circuit plates 10 together to aluminium matter stem stem 13 fill the span of a man's arms and the strip circuit plate on aluminium base 11 thermally coupled with aluminium matter stem stem 13, thereby the heat that the strip circuit plate produces can diffuse on the aluminium matter stem stem by the heat conduction.All strip circuit plates 10 end in the same way are contained on the upper casing 4 in the corresponding grooves 8, the other end in the same way contacts through the short tube 18 of transverse circuit plate 16 with lampshade 19 inner surface upper process, makes the axial location of all strip circuit plates 10 and aluminium matter stem stem 13 keep stable.
