Take a cheap ceiling light to see what?

My friend bought a few ceiling lamps. Let me see how the lamps are. Let’s take a look at them.
Exterior
1 appearance
This is a very common look.
Open the mask
2 open the mask
The transparent cover was opened and 32 5630 lamp beads were used, and the power was integrated into the lamp board.
3 transparent cover
This transparent cover acts to avoid contact with the live position after opening the mask.
Power IC
4 power IC
It is an innovation to attach the power IC directly to the light board.
5 various components are also directly attached to the light board
All kinds of components are also directly attached to the lamp board, many of which are hand soldered.
6 transformer welding
This transformer is a little bit soldered, will it block the light?
7 terminal block
The input line uses a terminal block, and the line via hole is protected by a rubber sleeve.
Ceiling lights are commonly used in home lighting, and their value is not as high as that of crystal chandeliers. The ceiling light functions as the main illumination, so performance is especially important. This ceiling light incorporates the power supply into the light panel to form an AC module that is easy to replace. This is an advantage. The disadvantage is that the power type electronic components on the lamp board can seriously affect the attenuation of the peripheral lamp beads. Long-term will cause color temperature, light flux shift, and form a failure.
