With the continuous acceleration of urbanization in recent years, there are more and more street lights for road lighting. LED street lamps are favored by people because of their energy-saving and environmental protection advantages, and the price of LED street lamps has also attracted people's attention. Many buyers often have such a doubt when buying
LED street lights: Why are the prices of the 'same' LED street lights different from different LED street light manufacturers? Today, the editor will take you to understand the reasons for the price differentiation of LED street lights, and hope that understanding these reasons will be more helpful to everyone's purchase.
1. LED lamp beads
The price of LED lamp beads in the market is more differentiated. Some LED lamp beads are sold very cheaply, and some are sold several times cheaper. Why does this happen? In fact, there are many tricky ones.
. Inexpensive LED lamp beads, first of all, its materials are very poor, these raw materials, the purchaser can not distinguish, only in the later stage of use can the problem slowly be exposed.
. Increase the power to use
LED street lights, usually only use W LED lamp beads, increase the power to W, far beyond the scope of use, this will cause very serious light decay, and the brightness will be reduced within a few months. Got lower.
.Virtual meter power, originally the normal use power of LED lamp beads is only W, and the virtual mark is W, so the purchaser cannot test it out.
Two, radiator
The quality of the radiator directly affects the service life of the LED street lamp. Nowadays, many LED lamps on the market are equipped with very small and thin radiators, which will cause poor heat dissipation and other phenomena when used for a long time, which will affect the service life of the LED lamp beads. Many businesses even lower the price of
LED street lights and choose not to install radiators. We can imagine the quality! Everyone knows how can a high-power LED street light without a radiator ensure stable heat dissipation? How to ensure the stable operation of the LED light source?
Three, power supply
The power supplies on the market are sub-branded power supplies, such as Taiwan Mingwei and the like. It is also produced in small OEM workshops. The power supply design produced by some small workshops cut corners and cut corners, which can be saved while saving, and does not consider the safety and stability of actual use. The price of using such LED street lights is cheap, but do you really dare to use them if you know these?
Fourth, the motherboard
There are generally two main boards in LED street lamps, one is constant current and the other is constant voltage main board. Constant current motherboards are more stable, and the price is twice as expensive as that of constant voltage. Most of the cheap LED lamps use a constant voltage differential main board, and the lamp body cannot be protected from rising temperature, which greatly reduces the service life of the LED lamps.
Five, shell
Cheap LED lamps use plastic shells or thin aluminum sheets, which have low cost, poor heat dissipation, and may burn out in severe cases.
These are the reasons for the price differentiation of LED street lights. After reading these, do you still dare to blindly choose low-priced LED street lights? In addition, when you are shopping, try to buy from large-scale LED
street light manufacturers. Under the current market environment, you must not be greedy to buy products cheaply!
