Some details of LED lamp bead lighting technology
Because of the long service life, energy saving, simple and convenient use, and low application cost of LED lamp beads, LED lamp beads become a green and clean light source and will be widely used in home lighting.
In order to show the characteristics of energy saving and long life of LED lamp beads, it is very important to select LED lamp bead driver ICs. Without the matching of good driver ICs, the advantages of LED lamp beads cannot be expressed.
LED lamp beads are environmentally friendly: LED lamp beads are a kind of green light source with better environmental protection benefits. There are no ultraviolet and infrared rays in the spectrum, low heat and no stroboscopic, no radiation, and the waste is recyclable, no pollution, no mercury element, cold light source, and safe contact.
High energy-saving LED lamp beads: DC drive, ultra-low power consumption (single tube 0.03W-1W) electro-optical power conversion is close to 100%, the same lighting effect saves more than 80% energy than traditional light sources. LED lamp bead long life: LED lamp bead solid cold light source, epoxy resin encapsulation, no loose parts in the lamp body, there are no defects such as easy burning of filament, heat accumulation, rapid light decay, etc., the service life can reach 50,000 100,000 hours, more than 10 times longer than traditional light sources.
Features of LED lamp beads: The VF voltage of LED lamp beads for lighting is very low, generally VF=2.75-3.8V, IF is 15-1400mA; low-power LED lamp beads are mostly used for LED fluorescent lamps, decorative lights, grille lights; large Power LED lamp beads are used for home lighting, spotlights, underwater lights, wall washer lights, street lights, tunnel lights, car work lights, etc. The power LED lamp bead is a device driven by low voltage and high current. The intensity of its light is determined by the current flowing through the LED lamp bead. Excessive current will cause the light attenuation of the LED lamp bead. Too weak current will affect the LED lamp bead. Therefore, the driving of LED lamp beads needs to supply constant current power supply to ensure the safety of high-power LED lamp beads.
