1. Look at the overall "power factor of lamps"

The low power factor means that the driving power supply and circuit design used are not good, which will greatly reduce the service life of the lamps.

2. Look at "Lamp Heat Dissipation Conditions-Material, Structure"

The heat dissipation of LED lamps is also very important. Lamps with the same power factor and lamp beads of the same quality, if the heat dissipation conditions are not good, the lamp beads work at high temperature, the light decay will be large, and the life of the lamp will be reduced.

3. Look at the "quality of lamp beads"

The quality of lamp beads depends on chip quality and packaging technology.

4. Look at the driving power used by the lamps

The service life of the power supply is much shorter than that of other parts of the lamps. The life of the power supply affects the overall life of the lamps. The design and material selection will determine the life of the power supply.

5. Look at the light effect

The same lamp bead power, the higher the light efficiency, the higher the brightness, the same lighting brightness, the lower the power consumption, the more energy-saving.

6. Look at power efficiency

The higher the power efficiency, the better. The higher the power, the smaller the power consumption of the power supply itself, and the greater the output power.

7. Is it to see if it meets the safety standards?

my country's LED lighting safety standards have been introduced, please choose LED lighting according to the national safety standards.

8. It depends on whether the workmanship is fine

A good quality LED lamp, in addition to the main aspects mentioned above, also has different technical requirements according to different use environments, such as moisture-proof, dust-proof, anti-magnetic, anti-lightning and so on.

Note: Alloy wire and gold wire are more likely to break during work than alloy wire, that is, it is more likely to die. Pure gold wire with sufficient thickness can withstand 60,000 hours, while alloy wire may be less than 30,000 hours. Other packaging factors, power supply factors, shell heat dissipation factors and environmental factors used, the life of the finished lamp will be shorter.

4. The difference between phosphors: white light lamp beads are made of blue light chips and phosphors. The phosphors are mainly divided into aluminates and silicates. The performance of aluminates is better than that of silicates, and aluminates are the most representative. YAG is YAG. YAG has stable performance and low light decay. Silicate itself has poor chemical stability, but its brightness is higher than YAG. If you want to make a product with stable performance, don't be fooled by the so-called high brightness. This is a big deal. question.

The quality of the phosphor directly determines the purity and durability of the light color of the light source. The reason why some light sources change color after a period of time is due to the lack of packaging technology and materials.

5. The difference between glue: phosphor powder should be mixed with glue and then placed on the chip. The quality of glue will affect light decay and color drift. Poor glue will yellow over time, and light decay will increase. Good glue It's jelly glue.
