2, cylindricality laminated construction
As shown in Figure 3, cylindricality laminated construction of the present utility model is:
Comprise the lamp holder 1 that connects successively, 2,1～100 layers of heat-dissipating cylinder 5 and double-sided printed-circuit board 3 that alternately connects of shell, in the end the double-sided printed-circuit board 3 of one deck is provided with LED4;
Be provided with LED4 between two adjacent heat-dissipating cylinders 5, the two poles of the earth of its LED4 are connected with two adjacent heat-dissipating cylinders 5 respectively.
Be arranged on the double-sided printed-circuit board 3 between the two adjacent heat-dissipating cylinders 5, the function of existing insulation spacer; The function that lead is arranged again promptly connects the two poles of the earth of LED4.
When lamination of the present utility model is a lot, be a kind of strip LED lamp, just like the fluorescent lamp of a strip, but its luminous efficiency height.
3, mix stacked structure
As shown in Figure 4, the stacked structure of mixing shape of the present utility model is: cylindricality laminated construction+pagoda shape laminated construction.
Its operation principle is: when lamp holder 1 access power supply, power supply is transferred to double-sided printed-circuit board 3 by lamp holder 1 and lead 8, makes the LED4 that is electrically connected with double-sided printed-circuit board 3 luminous.
The utlity model has following advantage and good effect:
1. power is big.The planar package of existing LED lamp is become three-dimensional encapsulation, and the two dimensional surface of existing LED lamp, luminous to become 3 D stereo luminous, can increase such lamp LED number widely, and the power of LED lamp is done becomes possibility greatly.
2. good heat dissipation.Heat-dissipating cylinder 5 is a kind of metal cylinder of gear-like, is provided with LED 4 between two adjacent heat-dissipating cylinders 5.Heat-dissipating cylinder 5 can reach better heat radiating effect, has conducting function again.
3. designs and varieties are many.The utility model has the stacked structure of pagoda shape, the stacked structure of cylindricality and mixes the stacked structure of shape, makes the LED lamp can make the designs and varieties of a lot of shapes, a lot of specifications, satisfies social various demand.
