1. Light quality and anti-glare effect: Light quality is the soul of a lamp, and whether the spot produced is beautiful or not will directly affect the effect. The pros and cons of anti-glare performance are also critical.
2. Look at the light efficiency: 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.
3. Look at the color temperature: whether the color temperature distribution is uniform will directly affect the lighting effect; and the color temperature and the color rendering index are related to each other, and the change of the color temperature will cause the change of the color rendering index.
4. Look at the 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.
5. Power factor of LED lamps: The low power factor indicates that the driving power supply and circuit design used are not good, which will greatly reduce the service life of the lamps. The process of die casting and cold forging is a more ideal choice at present.
6. The heat dissipation performance of LED lamps: the lower the thermal resistance, the better the heat dissipation. If the thermal resistance is high, the heat dissipation will be poor, so that the temperature of the device will increase, which will affect the wavelength shift of light. When the temperature rises by one degree, the wavelength of light will drift by 0.2-0.3nm, which will directly affect the quality of the light. Excessive temperature rise also directly affects the service life of high-power LED downlights.
7. Look at the material and structure of the heat dissipation conditions of the lamps. The heat dissipation of high-power lamps is also very important. The lamps with the same power factor and the lamp beads of the same quality, if the heat dissipation conditions are not good, the lamp beads will work at high temperatures, and the light decay will be very large. Lamp life will be reduced.
8. Whether the workmanship of LED lamps is fine: a high-power LED lamp with good quality, in addition to the main aspects mentioned above, also has different technical requirements according to different use environments, such as moisture-proof, dust-proof, etc. , this parameter can be known from its IP protection level.
9. Look at the quality of LED lamps and lanterns. The quality of lamp beads depends on chip quality and packaging technology.
