Patent ID: 8316534

Claim:
A method for packaging an airtight multi-layer array type LED, comprising: integrally forming a metal substrate with an airtight metal frame, the airtight metal frame forming a metal sidewall surrounding an accommodating space; forming a light outlet platform on a bottom of the accommodating space, the light outlet platform surrounding a light outlet opening; forming an airtight sealing groove around an upper surface of the airtight metal frame, a sealing frame wall being upwardly and vertically extended from an outer edge of a top surface of the airtight metal frame; forming two horizontal sealing through holes through the metal sidewall of the airtight metal frame, a lead frame being inserted through each of the horizontal sealing through holes, all interstitial space in the two horizontal sealing through holes being completely sealed with a sealing material; disposing a first light reflector to a sidewall of the light outlet platform, and disposing a second light reflector on an interior of the airtight metal frame, a lower portion of one side of the second light reflector being placed against an outside of the light outlet platform, an upper portion of the other side of the second light reflector being placed against an inner wall of the airtight metal frame, wherein the first and the second light reflectors receive light, and then reflect the received light outward; installing a plurality of LED dices on the bottom of the accommodating space, each of the LED dice being electrically connected to each other by wire bonding, the LED dices being electrically connected to the lead frame through a plurality of wires so as to form an electric circuit; forming a dice protection layer on the LED dices for covering and protecting the LED dices; forming a silicone layer on the dice protection layer; presetting a fluorescent layer inside an optical glass cover; and installing the optical glass cover with the fluorescent layer preset therein on a top surface of the airtight metal frame, wherein the optical glass cover is tightly jointed with the top surface of the airtight metal frame and an inner portion of the sealing frame wall.
