Light emitting diode module for lighting
View Patent ↗Provided is an LED module for lighting, which includes a printed circuit board (PCB); at least one or more LED elements mounted on the PCB; and a waterproof agent surrounding terminals between the PCB and the LED elements, which are exposed on mounting surface of the LED elements.
1. A light emitting diode (LED) module for lighting comprising:
a printed circuit board (PCB);
at least one or more LED elements mounted on the PCB; and
a waterproof agent surrounding terminals between the PCB and the LED elements, which are exposed on mounting surface of the LED elements,
wherein the waterproof agent is locally applied along the side surfaces of the LED elements.
2. The LED module for lighting according to claim 1 , wherein the PCB is a FR-4 board.
3. The LED module for lighting according to claim 1 , wherein the PCB is a metal core PCB.
4. The LED module for lighting according to claim 1 , wherein the PCB is a ceramic board.
5. The LED module for lighting according to claim 1 , wherein the waterproof agent exposes the top surface of the PCB excluding the mounting regions of the LED elements.
6. The LED module for lighting according to claim 1 , wherein the waterproof agent covers the top and side surfaces of the LED elements.
7. The LED module for lighting according to claim 1 , wherein the waterproof agent exposes the top surfaces of the LED elements.
8. The LED module for lighting according to claim 1 , wherein the waterproof agent is silicone.
9. The LED module for lighting according to claim 1 , wherein the silicone includes a silicone-resin coating agent.
10. The LED module for lighting according to claim 1 , wherein the water proof agent is epoxy.
11. The LED module for lighting according to claim 10 , wherein the epoxy includes an epoxy-resin coating agent.
12. The LED module for lighting according to claim 1 , wherein the PCB is fixed to an installation target through a double-faced tape.
13. The LED module for lighting according to claim 1 , wherein the PCB is fixed to an installation target through screws.
14. The LED module for lighting according to claim 13 , wherein the PCB has holes for fastening the screws, the holes being formed on the top surface of the PCB.
15. A method of manufacturing an LED module for lighting, comprising the steps of:
preparing a PCB;
mounting one or more LED elements on the PCB; and
applying a waterproof agent along the side surfaces of the LED elements, the waterproof agent covering terminals between the PCB and the LED elements,
wherein the waterproof agent is locally applied along the side surfaces of the LED elements.
16. The method according to claim 15 , wherein the applying of the waterproof agent is performed by a pneumatic dispensing method.
17. The method according to claim 15 , wherein the applying of the waterproof agent is performed by a tube-pressure-feed dispensing method.
18. The method according to claim 15 , wherein the applying of the waterproof agent includes the step of exposing the top surface of the PCB excluding the mounting regions of the LED elements.
19. The method according to claim 18 , wherein the applying of the waterproof agent includes the step of applying the waterproof agent on the top and side surfaces of the LED elements.
20. The method according to claim 18 , wherein the applying of the waterproof agent includes the step of applying the waterproof agent on only the side surfaces of the LED elements such that the top surfaces of the LED elements are exposed.
