Main Characteristics Of LED Lamp Beads
Leave a message
The main characteristics of LED lamp beads include the following aspects:
High efficiency: After decades of technical improvements, the luminous efficiency of LED lamp beads has been significantly improved. Incandescent lamps and halogen lamps have a luminous efficiency of 12-24 lumens/watt, fluorescent lamps have a luminous efficiency of 50-70 lumens/watt, sodium lamps have a luminous efficiency of 90-140 lumens/watt, and LED luminous efficiency can reach 50-200 lumens/watt, and the light has good monochromaticity and a narrow spectrum, and can directly emit colored visible light without filtering.
Long life: The life of LED lamp beads far exceeds that of traditional lighting equipment. For example, the luminous efficiency of a white light LED with a diameter of 5 mm can theoretically exceed 150lm/W, and the life span can reach more than 100,000 hours, far exceeding other lighting equipment.
Low power consumption: LED lamp beads are driven by DC, with a single tube power of only 0.03-0.06 watts, a current of 15-18 mA, a fast response speed, and can operate at high frequencies. Under the same lighting effect, the power consumption of LED lamp beads is only one ten-thousandth of that of incandescent bulbs and one-half of that of fluorescent tubes.
Environmental protection: LED lamp beads do not contain harmful substances such as mercury, and almost no heat is generated during operation, which is environmentally friendly.
High reliability: With the advancement of heat dissipation technology, high-power LED lamp beads have been widely used in outdoor lighting fields, such as street lights and floodlights. At the same time, indoor lighting with strict requirements on color temperature and color rendering, such as stage lights and studio lights, has also been mass-produced and put into use.
Diversity and flexibility: The emitting angle and color of LED lamp beads can be adjusted according to needs, suitable for various lighting scenarios. The smaller the emitting angle, the higher the brightness; there is no direct correlation between color temperature and brightness, but brightness and lumen value are closely related.
