Abstract

The invention discloses a packaging structure for a light emitting diode light source, which comprises a first stamping metal sheet, a second stamping metal sheet, a third stamping metal sheet, a plurality of pieces of light emitting diode chips arranged on the second stamping metal sheet, and a control circuit board connected with the light emitting diode chips, wherein the second stamping metalsheet is provided with an installation port capable of fixing the control circuit board; the third stamping metal sheet is provided with a plurality of through openings for limiting a point fluorescent powder rubber area; the light emitting diode chips are attached to a position where the second stamping metal sheet corresponds to the through openings; and the first stamping metal sheet, the second stamping metal sheet, and the third stamping metal sheet are fixed via a connection mechanism. The packaging structure for the light emitting diode light source is good in heat radiating effect, and high in reflection strength; meanwhile the power supply power factor is up to 0.92 or above, and the power supply efficiency is up to about 90 percent, so that the structure is more convenient to use.

Description

technical field [0001] The invention relates to the field of lighting equipment, and more specifically refers to a packaging structure of a light emitting diode light source. Background technique [0002] At present, the light-emitting diode light source and the power driver are mostly separated, and some of them are driven by low-voltage DC power supply. The power supply below 8 watts has a low power supply efficiency, which is about 85% or less, and the power factor is also low, about 0.85 or less. ; Some parts use high-voltage AC LEDs, and their AC power is directly connected to multiple strings of LEDs, but due to changes in their voltage, it is easy to cause current fluctuations; some use electrolytic capacitors to step down and stabilize the current, but their power supply Factors are generally below 0.5, resulting in waste of grid power supply. Contents of the invention [0003] The present invention provides a package structure of a light emitting diode light sour...
