1. Chips
The price of LED chips is uneven in the market. Why do some lamp chips sell so cheaply? The price of some lamp chips is dozens of times different. In fact, there is something tricky about it.
First of all, its materials are definitely the worst. For example, copper wires are used for bonding wires instead of gold wires, and brackets are produced with recycled materials or scraps. Consumers cannot determine these raw materials. The problems are slowly exposed only after use.
The second is to increase the power usage. Originally, the normal use power of the lamp chips may be only 1W/0.75W, and the power is increased to 3W, which is beyond the scope of use. The initial brightness is very high, but it decays quickly, and it will be dark within a few months.
The virtual standard power is again, the standard is 3W lamp beads, the real standard is to use 1W or 0.75W lamp chips instead, or even lower, this consumer generally did not test.
2. Radiator
When the lamp beads emit light, part of the electrical energy is converted into heat energy, which will directly affect the service life of the lamp beads.
The LED par light radiator can be identified by the naked eye when consumers disassemble the lamp shell. At present, many par lights on the market are equipped with very small and thin radiators, and even many businesses do not install radiators at all in order to compete for the price.
3. Drive power
Many low-priced driving power supplies on the market are false standards or use LED lights that cannot drive the rated power at all.
A good drive power component arrangement and production process are also relatively good, and the overall look is clean, tidy and beautiful. The low-cost and insecure driving power supply is designed to cut corners and cut corners. The surge prevention, rectification and filtering, and current stabilization can save energy, and can not save. Electronic components are also useful for recycling materials, and the safety and stability of actual use are completely ignored.
