Why is it cheap LED lights?

The led lighting industry development is rapid, all kinds of lamps and lanterns design is various. LED lights factory it is a solid cold light source, green pollution-free, less power consumption, high photosynthetic efficiency, long life, therefore, the LED street light will become the best choice of the road lighting energy saving reconstruction. LED street lamp which is a kind of based on semiconductor PN junction formation with a weak electricity can glowing efficient solid-state light source, in certain positive bias voltage and the electrical flow injection, injection of holes and injection P N the electronic after spread to have source area by the radiative recombination and emit photons, convert electrical energy directly into light energy. Price difference is very obvious. LED street lamp which is a kind of based on semiconductor PN junction formation with a weak electricity can glowing efficient solid-state light source, in certain positive bias voltage and the electrical flow injection, injection of holes and injection P N the electronic after spread to have source area by the radiative recombination and emit photons, convert electrical energy directly into light energy. There are a lot of led and led lighting manufacturers. The quality of different manufacturers use different led lead to different leds. Due to the increasingly fierce price war, appearance, structure, function almost the same products, price is 2 - Three times. Many users temporarily confused, I don't know the price difference where it came from. Is generally not in the production of led tube led lighting manufacturer it is difficult to distinguish. Especially the consumers. Therefore, choose a good LED production source, or has perfect LED test equipment, LED lighting factory will be better, to buy the LED lamps will be safer. Let's take a look at what factors lead to the difference between the price of LED lights: 1. Different brightness and brightness: price of LED. Brightness is different from the wattage. It is represented with the lumen. It refers to the unit within the space of light intensity. General indoor - 100 600 lux. 2, antistatic ability, antistatic ability, long service life, so the price is high. Usually antistatic led more than 700 v can be used for led lighting. Wavelength: LED? If necessary, on the same wavelength in color is the same? If the same color, the price is high. No LED spectrometer is difficult to produce pure color products. 4. Leakage current: LED is a one-way conductive light emitting device. If there is a reverse current, it is called a leak, the leakage current big LED short service life, low price. 5. Light Angle: different USES leds have different light Angle. Special light Angle, the price is higher. If the full diffusion Angle, the price is higher. Different life: quality is the key to life. Life is determined by the attenuation of light. Droop, long life, long life, high price. LED chip, LED light is chip, different chips, prices vary considerably. Chip prices more expensive in Japan and the United States, factories in Taiwan and mainland China manufacturers LED chip price is lower than Japan and the United States. 8, chip size: the size of the chip to side, said big LED chip quality is better than that of small chips. The price is proportional to the chip size. The LED lighting market there are still some criminals, cheat supplier, cheat production of finished products, materials suppliers to abnormal low-priced sales of finished products for cash. There are a few LED lighting manufacturers to unrealistic promises on distributors and users, and then by changing the head of the enterprise name or strategy to shirk responsibility. Accordingly, when consumer is buying lamps and lanterns must pay more attention to these details, do more comparison, some reference opinions. The choose and buy Suggestions: 1. In terms of brand, brand has its own factory and r&d team. They are usually direct contact with terminal customers. No dealers earn the difference, price and quality guaranteed. two Leds are certified high-tech enterprises, with the support of the country, needs to have 3 c, CER, ROHS certification, etc. 3. Look at the hardware, chips, power supply and packaging are the core components. You can skip the domestic brands or domestic package. 4.
