Do you know how LED bulbs are composed?
Author:
LED bulbs I believe that all electrician friends are familiar with it. Comparison must be in the same quality to have contrast, determine the price of a bulb from the structure of the bulb material to determine.
The components of a complete LED bulb light are: LED light source board (semi-finished product of LED lamp beads that have been welded), LED drive power supply (including input and output leads), bulb shell, bulb shade and supporting lamp head (E27, E14, B22 and other specifications).
1. Bulb shell
Let's start with the shell of the LED bulb, the material used in the LED bulb shell is divided into PP material, ABS material, PBT material, PC material, and the price of PP material is the lowest in terms of cost.
Among them, the cost of PBT and PC material is relatively high, and the shell made of PC material is relatively smooth and beautiful.
The LED lamp shell made of PBT material is generally frosted, and the frosted feels comfortable and relatively high-grade.
2. Bulb cover
The lampshade of LED bulb is usually made of PC and PP material, and the cost of PP material is low.
PC material is relatively soft. Good light transmission. The light bulb is turned on for high brightness.
PP material is relatively soft, light transmittance is relatively poor, and the brightness is low.
3. Drive power
The driving power supply of LED bulbs is like the heart of the human body, determining the life of the bulb, and the role of the drive power supply is to convert the power supply (general household 220V) into a specific voltage and current suitable for LED bulbs.
