The garden landscape lighting project is accompanied by vicious price competition in the LED lamp sales market. The sale of a large number of substandard products has already violated some of its own real use values such as LED environmental protection, energy saving, longevity, and environmental protection. So how do you identify What are the advantages and disadvantages of LED outdoor lighting engineering lamps?
1. First look at the overall "output power factor of lamps and lanterns": the output power factor is low, indicating that the driving power supply and circuit principle of the application are not very good, which will greatly reduce the service life of the lamps and lanterns. The output power factor is low, and the application of LED lamp beads is better. The service life of the lamps will not be long.
2. Look at "lamp heat dissipation standard - raw materials, structure": LED lighting engineering lamps and lanterns heat dissipation is also very critical. Lamps with the same output power factor and LED lamp beads of the same quality, if the heat dissipation standard is not very good, LED lamps When the beads work at high temperature, the light loss will be very large, and the service life of the lamp will be reduced.
3. Look at "LED lamp bead quality": The quality of LED lamp beads depends on the quality of integrated IC and packaging technology.
4. Looking at the driving power supply used in lamps and lanterns, the service life of the switching power supply is much shorter. The service life of the switching power supply will immediately endanger the service life of the lamps. According to the basic theory of all normal LED lamp beads, the service life is between 50,000 and 100,000 hours. , and the service life of the switching power supply is 0.2-30,000 hours, so the design scheme and material selection of the switching power supply will determine its service life.
5. Look at the special effects: the same LED lamp bead output power, the higher the special effect, the higher the chromaticity, the same lighting chromaticity, the smaller the power consumption, the more environmentally friendly and energy-saving.
6. Look at the power efficiency. The higher the power efficiency, the better. The higher the power, the smaller the functional loss of the switching power supply itself, and the greater the output power.
7. To see if it meets the testing standards? In my country, the testing standards for LED outdoor lighting lamps have long been promulgated, and LED lighting engineering lamps are selected according to the testing standards stipulated by the state.
