The technical characteristics, features and advantages of the present invention will become apparent in the following detailed description of the preferred embodiments with reference to the accompanying drawings. However, the drawings are provided for reference and illustration only and are not intended for limiting the scope of the invention.
Referring to
The LED lamp set 1 includes a casing 10 and an LED module 20, and the casing 10 forms a cone 11 at the bottom of the casing 10, and the cone 11 forms a containing hole 12 at the top of the cone 11. A plurality of corresponding stopping members 13 are protruded from an internal edge of the containing hole 12, and each stopping member 13 includes a through hole 131, and each stopping member 13 includes a positioning member 14 extended from the left side of the containing hole 12, and two corresponding support stands 15 extended outward from the top surface of the cone 11. The support stand 15 is substantially in an L-shape, and its short arm has a latch portion 151 formed on the internal side. Two inverted L-shape fixing stand 16 are disposed between two support stands 15, and a slab 161 is extended horizontally from an end of the fixing stand 16, and a through hole 162 is disposed at the center of the slab 161, and the cone 11 has a stairway ring 17 disposed at the bottom of the cone 11 as shown in
The LED module 20 is contained in the containing hole 12 of the casing 10 and the LED module 20 includes a base board 21 and a plurality of LEDs 22 fixed onto the bottom surface of the base board 21, a center hole 211 disposed at the middle of the base board 21, and a plurality of fixing holes 212 disposed around the external periphery of the center hole 211. The base board 21 has a stopping surface 213 disposed on a side of the base board 21 and attached onto a positioning member 14 of the casing 10, such that the base board 21 will be rotated after the base board 21 is installed in the casing 10. A protruding pillar 221 is extended from the rear of each LED 22 and embedded and connected to the fixing hole 211 of the base board 21.
The heat dissipating module 5 has an isothermal board 50 installed onto a side of the support stand 15 of the casing 10, and one of the sides is attached and connected to the base board 21 of the LED module 20, and the other side is latched to the latch portion 151 of the support stand 15. To cope with the heat dissipating requirements of various different types of LED modules 20, a heat dissipating plate (not shown in the figure) improves the thermal conduction and dissipation of the heat dissipating module 5. The isothermal board 50 of this embodiment includes a circular upper plate 51 and a corresponding circular lower plate 52 engaged to the bottom of the upper plate 51, and capillary tissues and operating fluids are filled into the lower plate 51, 52 to form a vacuum chamber, such that the thermal conduction mechanism of the gas and liquid phases are used for achieving a quick heat conduction effect, and the center of the isothermal board 50 has a wiring hole 53, and a power cable (not shown in the figure) can be passed through the wiring hole 53 to the outside for an electric connection.
The structure of the present invention further includes a plurality of elastic bodies 6, each having a cylindrical fixing section 61 and a circular disc clamping section 62 expanded outward from the fixing section 61, and the fixing section 61 is embedded into the through hole 131 of the stopping member 13, and the clamping section 62 is clamped between the corresponding surfaces of the stopping member 13 and the base board 21 of the LED module 20, such that the isothermal board 50 and the base board 21 can be attached closely with each other to improve the heat conducting effect.
In the assembling process, the fixing section 61 of each elastic body 6 is installed into the through hole 131 of the stopping member 13, and then the LED module 20 is installed in the containing hole 12 of the casing 10, such that the bottom surface of the base board 21 of the LED module 20 is attached and coupled onto the top of the clamping section 62 of each elastic body 6, and then the isothermal board 50 corresponding to the LED module 20 is installed at the top of the casing 10 for pressing the isothermal board 50 to move downward, and the top surface of the isothermal board 50 is latched by the latch portion 151 of the support stand 15. Therefore, a quick assembling structure for the LED lamp set and the heat dissipating module can be achieved. The present invention not only reduces the labor cost required for the assembling process significantly, but also lowers the material cost for a fixing element such as a screw as well.
Referring to
When the LED lamp is turned on, a current passes through the LED module 20, such that each LED 22 emits light and produces heat, and the heat is conducted from the base board 21 to the isothermal board 50, and the fluid phased heat conduction mechanism of the isothermal board 50 brings the heat to the top quickly and exchanges the heat with external cold air, and thus each LED 22 can be operated at a lower temperature and the life expectancy of the LED 22 can be extended.
Referring to
In summation of the above description, the quick assembling structure for LED lamp and heat dissipating module in accordance with the invention herein enhances the performance than the conventional structure and further complies with the patent application requirements.
The present invention are illustrated with reference to the preferred embodiment and not intended to limit the patent scope of the present invention. Various substitutions and modifications have suggested in the foregoing description, and other will occur to those of ordinary skill in the art. Therefore, all such substitutions and modifications are intended to be embraced within the scope of the invention as defined in the appended claims.
