8 Best Wholesale LED lights Suppliers in China / USA

The LED light is an electroluminescent semiconductor material chip, which is cured with silver or white glue to the bracket, and then connected to the chip and the circuit board with silver wire or gold wire. The periphery is sealed with epoxy resin to protect the inner core wire. Function, and finally install the outer casing, so the LED light has good seismic performance.

How do LED lights work?

LED lights, light-emitting diodes, are solid-state semiconductor devices that convert electrical energy into visible light, which convert electricity directly into light. The heart of the LED is a semiconductor wafer with one end attached to a holder, one end being the negative pole and the other end connected to the positive pole of the power supply, so that the entire wafer is encapsulated by epoxy.

The semiconductor wafer consists of two parts, one part is a P-type semiconductor, in which the hole dominates, and the other end is an N-type semiconductor, which is mainly electrons here. But when the two semiconductors are connected, they form a P-N junction. When a current is applied to the wafer through the wire, the electrons are pushed toward the P region. In the P region, the electrons recombine with the holes, and then the energy is emitted in the form of photons. This is the principle of LED light emission. The wavelength of light, which is the color of light, is determined by the material that forms the P-N junction.

The LED can directly emit red, yellow, blue, green, cyan, orange, purple, and white light.

The LED was originally used as an indicator light source for instrumentation. Later, various light-colored LEDs were widely used in traffic lights and large-area displays, resulting in good economic and social benefits. Taking a 12-inch red traffic light as an example, in the United States, a 140-watt incandescent light with long-life, low-light performance was used as a light source, which produced 2000 lumens of white light. After passing the red filter, the light loss is 90%, leaving only 200 lumens of red light. In the newly designed light, Lumileds used 18 red LED light sources, including circuit losses, to consume 14 watts of electricity, which would produce the same light effect. Automotive signal lights are also an important area for LED light source applications.

For general lighting, people need a white light source. In 1998, white LEDs were successfully developed. This LED is made by encapsulating a GaN chip and yttrium aluminum garnet (YAG). The GaN chip emits blue light (λp=465nm, Wd=30nm), and the Ce3+-containing YAG phosphor prepared by high-temperature sintering is excited by the blue light to emit yellow light, and the peak value is 550n LED light m. The blue LED substrate is mounted in a bowl-shaped reflective cavity covered with a thin layer of resin mixed with YAG, about 200-500 nm. The blue portion of the LED substrate is absorbed by the phosphor, and the other portion of the blue light is mixed with the yellow light emitted by the phosphor to obtain white light.

For the InGaN/YAG white LED, by changing the chemical composition of the YAG phosphor and adjusting the thickness of the phosphor layer, white light of various colors having a color temperature of 3500 to 10000 K can be obtained. This method of obtaining white light by a blue LED has the advantages of simple structure, low cost, and high technical maturity, and thus is most used.

Why is LED lighting better?

Led lights have the following advantages over traditional light sources:

1. New green environmental protection light source: LED uses cold light source, glare is small, no radiation, no harmful substances are produced during use. The LED has low operating voltage, adopts DC drive mode, ultra-low power consumption (single tube 0.03~0.06W), and the electro-optical power conversion is close to 100%, which is more than 80% energy saving than the traditional light source under the same lighting effect. LEDs have better environmental benefits, no ultraviolet and infrared rays in the spectrum, and waste can be recycled, no pollution, no mercury, and can be safely touched. It is a typical green lighting source.

2 .Long life: LED is a solid cold light source, epoxy resin package, anti-vibration, there is no loose part in the light body, there is no shortcomings such as filament light-emitting, heat deposition, light decay, etc. The service life can reach 60,000~100,000. Hours are more than 10 times the service life of traditional light sources. The LED performance is stable and can work normally in -30~+50°C environment.

3.Multi-transformation: LED light source can use the three primary colors of red, green and blue. Under the control of computer technology, the three colors have 256 gray levels and can be mixed arbitrarily, which can produce 256X256X256 (ie 16777216) colors, forming different light colors. The combination. The color of the LED combination is varied, enabling a variety of dynamic changes and various images.

4.High-tech: Compared with the light-emitting effect of traditional light sources, LED light source is a low-voltage microelectronic product, which successfully combines computer technology, network communication technology, image processing technology and embedded control technology. The size of the chip used in the conventional LED light is 0.25 mm×0.25 nm, and the size of the LED for illumination is generally 1.0 mm×1.0 mm or more. The LED die-formed work-table structure, inverted pyramid structure, and flip-chip design can improve its luminous efficiency and emit more light. Innovations in LED package design include high-conductivity metal block substrates, flip-chip designs, and bare-plate cast leadframes. These methods can be used to design high-power, low-thermal resistance devices, and these devices have higher illumination than conventional LEDs. The illuminance of the product is greater.

A typical high-throughput LED device can generate lumens of several lumens to tens of lumens, and an updated design can integrate more LEDs in a single device or install multiple devices in a single assembly, resulting in equivalent lumens output. For small incandescent lights. For example, a high-power 12-chip monochrome LED device can output 200 lm of light energy, which consumes between 10 and 15 W.
