How to choose SKD Raw Material Lampara Led Bulb Light?
1. Profile and structure
There are basically three types of SKD Raw Material Lampara Led Bulb Light profiles on the market: full plastic, half plastic half aluminum tube, and pure aluminum.
The all-plastic material has excellent insulation and can avoid electric shock problems, but the heat dissipation is poor and the light decay is serious; the semi-plastic and semi-aluminum material SKD Raw Material Lampara Led Bulb Light has better heat dissipation and a relatively long life; pure aluminum material SKD Raw Material Lampara Led Bulb Light not only has good heat dissipation, but also is safe and durable.
The power supply of SKD Raw Material Lampara Led Bulb Light is divided into two types: built-in type and external type. The so-called built-in type means that the power supply can be placed inside the lamp tube and can be made to directly replace the existing fluorescent lamp tube without any circuit modification.
Therefore, the built-in shape is made into a long strip so that it can be inserted into the semi-circular lamp tube.
Centralized external power supply: In order to get the highest performance, it is best to use a centralized external power supply. Because the main places to promote LED fluorescent lamps are government agencies, offices, shopping malls, schools, underground parking garages, subways and other places, often more than one fluorescent lamp is used in a room, maybe more than 10.
Its advantages are: the highest efficiency and maximum power factor can be obtained.
3. Chips, under normal circumstances, the quality of first-tier brands is definitely better than that of second-tier or Taiwanese brands. Currently used in fluorescent lamps are 3528, 3020, 3014 and other specifications. These specifications are mainly due to their different sizes and chip heat dissipation methods.
SKD RAW MATERIAL LAMPARA LED BULB LIGHT LED Driver Technology
LED lighting is conditional. A forward voltage is applied across its PN junction so that the PN junction itself forms an energy level (actually a series of energy levels) at which electrons jump and generate photons to emit light. Therefore, the voltage applied across the PN junction is required to drive the SKD RAW MATERIAL LAMPARA LED BULB LIGHT LED to emit light. And because LEDs are characteristic-sensitive semiconductor devices with negative temperature characteristics, they need to be stably operating and protected during the application, resulting in the concept of LED "driving".
SKD RAW MATERIAL LAMPARA LED BULB LIGHT LED driving principle
In the field of LED lighting, to reflect the characteristics of energy saving and long life, it is very important to choose a good LED driving circuit. Without the matching of a good driving circuit, the advantages of LED lighting cannot be reflected.
SKD RAW MATERIAL LAMPARA LED BULB LIGHT driver needs to convert high-voltage alternating current into low-voltage alternating current (AC/AC), and then rectify low-voltage alternating current into low-voltage direct current (AC/DC), and then pass high-efficiency DC/AC. The DC switching regulator steps down and converts it into a constant current source, and outputs a constant current to drive the LED light source. The LED light source is composed of multiple strings and multiple parallels of low-power or high-power LEDs according to the design requirements of the lamps. The IF current of each string is designed according to the selected LED light source IF requirements, and the total forward voltage △UF is the sum of N LEDs. SKD RAW MATERIAL LAMPARA LED BULB LIGHT can consider a non-isolated power supply if the AC power supply below 36V is used. If the AC power supply of 220V and 100V is selected, an isolated power supply should be considered.
GENERAL TECHNICAL REQUIREMENTS FOR SKD RAW MATERIAL LAMPARA LED BULB LIGHT LED DRIVER
High efficiency and high reliability. SKD RAW MATERIAL LAMPARA LED BULB LIGHT is an energy-saving product, and the drive power is more efficient. It is especially important for the structure where the power supply is installed in the luminaire. Because the luminous efficiency of the LED decreases with the increase of the LED temperature, the heat dissipation of the LED is very important. The efficiency of the power supply is high, its power loss is small, and the heat generated in the lamp is small, which reduces the temperature rise of the lamp. At the same time, it also delays the light decay of the LED, which is beneficial to improve the service life of the entire SKD RAW MATERIAL LAMPARA LED BULB LIGHT.
