Casting for an LED module
View Patent ↗A casting adapted to carry a light emitting diode die and an anti-static die is disclosed. The casting comprises two electrodes for opposite electrodes and a wall. The light emitting diode die is mounted one of electrodes and the anti-static die is mounted on the other electrode. The wall is arranged between the light emitting diode die and the anti-static die. Further, the height of the wall is larger than that of the anti-static die to shade the anti-static die, whereby reflecting the light emitted from the light emitting diode die. Therefore, the reflection ratio of the light emitting diode die is improved, and the intensity generated by the whole light emitting diode is also improved.
1. A casting adapted to carry a light emitting diode die and an anti-static die, the casting comprising:
a cup shaped portion, the light emitting diode die and the anti-static die disposed therein, said light emitting diode die being displaced from said anti-static die within said cup shaped portion;
two electrodes disposed in the cup shaped portion, the light emitting diode die being mounted on one of the electrodes and the anti-static die mounted on the other electrode;
a wall disposed within said cup shaped portion, said wall mounted between and contiguous said two electrodes, wherein said wall partitions said cup shaped portion into a first cavity and a second cavity, said first cavity containing said light emitting diode die and said second cavity containing said anti-static die whereby the light emitted by said light emitting diode die is reflected from said wall of the first cavity without any interference of said light by said anti-static die, the height of said wall being greater than that of the anti-static die and lower than that of the casting;
wherein the light emitting diode die connects with the two electrodes via two first wires, and the anti-static die be electrically connected with the electrode which the light emitting diode die mounted thereon via a second wire.
2. The casting as claimed in claim 1 further comprising an encapsulation layer covering the light emitting diode die and the anti-static die provided in the casting.
3. The casting as claimed in claim 1 , wherein the casting and the wall are made of a high polymer insulated material.
4. The casting as claimed in claim 1 , wherein the light emitting diode die is insulatedly mounted on one of the electrodes.
5. The casting as claimed in claim 1 , wherein the anti-static die is soldered on one of the electrodes.
