US 7498610 B2Abstract
1. An light emitting diode housing comprising:
a heat conducting part having:
a chip mounting area for mounting a light emitting diode chip;
a heat connecting area opposed to the chip mounting area; and
a neck that is formed between the chip mounting area and the heat connecting area, the neck having a groove formed around the heat conducting part;
a pair of fixing parts configured to fix the heat conducting part, each fixing part having a holder formed at a first end engaged with the neck of the heat conducting part, the holder being inserted into the groove formed in the neck;
an electrical connecting part having a wire connecting area placed adjacent to the chip mounting area of the heat conducting part and an external power connecting area connected to the wire connecting area; and
a housing body of molding material integrally holding the heat conducting part, the fixing parts and the electrical connecting part while isolating the electrical connecting part from the heat conducting part and the pair of fixing parts,
wherein the electrical connecting part and the heat conducting part are configured as a first terminal and second terminal, respectively.
2. The light emitting diode housing according to claim 1, wherein the first end of the fixing parts is adapted to hold around the neck.
3. The light emitting diode housing according to claim 1, wherein the fixing parts have a hole for receiving a portion of the housing body.
4. The light emitting diode housing according to claim 1, wherein the fixing parts each have a second end extended to a side surface of the housing body to spread heat from the heat conducting part in lateral direction of the housing body.
5. The light emitting diode housing according to claim 4, wherein the housing body has a caved-in side portion so that the second ends of the fixing parts are projected out of the housing body.
6. The light emitting diode housing according to claim 1, wherein the housing body has a cavity configured to expose the chip mounting area of the heat conducting part and the wire connecting area of the electrical connecting part.
7. The light emitting diode housing according to claim 6, wherein the housing body has a step connected around the chip mounting area of the heat conductive area within the cavity.
8. The light emitting diode housing according to claim 1, wherein the housing body has a groove connected around the heat connecting area of the heat conducting part.
9. The light emitting diode housing according to claim 1, wherein the holder is curved inward with a curvature corresponding to an outer surface of the neck. Description
This application claims the benefit of Korean Patent Application No. 2005-13249 filed on Feb. 17, 2005, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.
The fabrication method of the invention may further comprise a step of: (g) curing the molding material and taking out a cured resultant structure before or after the cutting step (f)
As shown in FIG. 20, the top surface of each electrical connecting part 130 adjacent to the first end 130 a forming the wire mounting area is exposed from above the cavity C of the housing body 150. A middle portion of the electrical connecting part 130 between the first and second ends 130 a and 130 b is inserted between the upper and lower pars 150 a and 150 b of the housing body 150, and a portion of the electrical connecting part 130 adjacent to the second end 130 b is extended out of the housing body 150. The fixing portions 156 of the housing body 150 are inserted into the indentations 132 of the electrical connection parts 130 thereby securely coupling the electrical connecting parts 130 so that the electrical connecting parts 130 do not slip out of the housing body 150 under external force.
When resin is cured, the above-mentioned resultant structure is taken out of the mold, the fixing parts 120 are cut along the line L1 shown in FIG. 19, and the electrical connecting pars 130 are cut along the line L2 shown in FIG. 20 to separate the resultant structure shown in FIGS. 18 to 20 from the frame 140. Then, the electrical connecting parts 130 are bent at the second ends 130 a as shown in FIG. 20, thereby producing an LED housing 100 as shown in FIG. 3 to 7. Alternatively, the step of taking the resultant structure out of the mold can be carried out the cutting and bending.
