Abstract
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.

Examples
Embodiment 1
[0026] Such as figure 1 , figure 2 As shown, a package structure of a light-emitting diode light source includes a first stamped metal sheet 1, a second stamped metal sheet 2, and a third stamped metal sheet 3 in a circular structure, which are attached to the second stamped metal sheet 2. The light-emitting diode chip 4, the PCB circuit board 5 connected with the light-emitting diode chip 4, the second stamping metal sheet 2 is provided with the installation port 21 that can fix the PCB circuit board 5, and the third stamping metal sheet 3 is provided with There are six openings 31 that limit the areas of fluorescent powder glue, and the above-mentioned light-emitting diode chips 4 are attached to the six areas of the second punched metal sheet 2 corresponding to the through holes 31; the second punched metal sheet 2 is along the The second stamped metal sheet 2 is evenly arranged with three bayonet sockets 22 on the circumference, and the third stamped metal sheet 3 is eve...
Embodiment 2
[0032] This embodiment is roughly the same as Embodiment 1, as image 3 , Figure 4 As shown, only a convex portion 6 is provided at the position of the limit opening 33 of the third punched metal sheet 3, the convex portion 6 is conical or arc-shaped, and the convex portion 6 can cover the PCB circuit board 5 to avoid The light is absorbed by the PCB circuit board 5 .
