DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to FIGS. 2 to 4, there is shown a multi-layer reflective lampshade comprising a light-bulb seat 1, an insulation layer 13, a main heat dissipation housing 4, a heat conductive seat 35, a LED bulb 3, and an auxiliary heat dissipation housing 2.
The external section of the light bulb seat 1 is mounted with a standard connector 22 and the internal section of the light bulb seat 1 is provided with a power source device 12. The insulation layer 13 is used to insulate the power source device 12 and the auxiliary heat dissipation housing 2. The light bulb seat 1 is provided with a plurality of protruded pillars 14 and wirings of the circuit board is exposed externally.
The auxiliary heat dissipation housing 2 is a conic body with through holes and the bottom section thereof is an opening 21 with an inner folded edge 22, and the folded edge 22 is provided with a plurality of relative holes 24.
The main heat dissipation housing 4 is a through body and a conic shape body of smaller size as compared to that of the auxiliary heat dissipation body 2. The upper section opening 41 has an inner folded edge 42 which is provided with a plurality of connection holes 44.
The front section of the LED bulb body 3 is a metal heat body 31 of good heat conductivity and with a carrier face 32 to hold a single or more than one LED chips 33. The metal heat body 31 is circular and the rear end is protruded to mount to the connection legs 36 of the chip.
The heat conduction seat 35 is used for the mounting of the LED bulb body 3, and the heat conduction seat 35 is provided with a plurality of connection holes 34, and the center of the heat conduction seat 35 is a circular recess 351. The interior of the recess 351 is provided with a plurality of leg holes 352 such that the connection legs 36 of the chip that passed through are mounted at the rear end of the heat conduction seat 35.
As shown fri FIGS. 4 and 5, the multi-layer reflective lampshade makes use of the main heat dissipation housing 4 as light source distribution and the through holes 20 on the main heat dissipation housing 4 and the auxiliary heat dissipation housing 2 are used for heat dissipation via convection current such that LED light bulb body 3 could dissipate heat externally to the main heat dissipation housing 4 and the auxiliary heat dissipation housing 2. More main heat dissipation housing 4 and auxiliary heat dissipation housing 2 are used to increase heat dissipation surface which increases heat dissipation efficiencies and lower the temperature of LED light bulb body 3. This will prevent heat being accumulated.
Thus, the LED light bulb body 3 will increases the light emission efficiency and the longevity of light bulb is increased.
