Light emitting diode having a phosphor layer, heat

The present invention discloses a light emitting diode having a phosphor layer, heat dissipation, the upper edge region of the negative electrode of the LED heat sink above the annular tacky ceramic sheets, ceramic sheets tacky annular ring metal heat sink, an annular metal heat sink a positive electrode provided with an LED, and the heat sink above the key central region of the negative electrode co LED chips LED, the LED chip and wire bonding is through LED, is coated with a phosphor layer between the electrodes on the LED chip, bonding the optical lens the annular metal heat sink, wherein: the surface of the phosphor layer vapor-deposited coating is connected to the heat transfer, the heat transfer fins plated with a metal ring. Phosphor of the present invention may be maintained at a lower working temperature, such that the phosphor has a long service life, and the color temperature does not change, while ensuring LED life.
