Lighting power consumption accounts for 19% of the world's total electricity consumption, of which 83% of lighting power consumption comes from commercial buildings and outdoor lighting, so many energy-saving lighting technologies are derived. LED light source technology is a very characteristic one. It was less than two years since the LED was displayed to the lighting and lighting. With the factory, business, and media together, the LED Lighting has not started with a recognized brand, and the price war started earlier. The appearance, structure, and functionality of almost the same product, the price difference is 2-3 times, many users were confused for a moment, I do not know where the spread comes from, what kind of price products. Here are some more intuitive explanations for readers of these differences.
1, LED light source characteristics (1) voltage: LED uses low-voltage power supply, the supply voltage is between 6-24V, varies from product to product, so it is a safer power than the use of high voltage power supply, especially suitable for public places.
(2) Performance: 80% less energy than incandescent lamps with the same efficacy.
(3) Applicability: Very small, each unit LED chip is a 3-5mm square, so it can be prepared into a variety of shapes of devices, and is suitable for a volatile environment.
(4) Stability: 100,000 hours, light decay is the initial 50%.
(5) Response time: The response time of its incandescent lamp is milliseconds, and the response time of the LED lamp is nanoseconds.
(6) Environmental pollution: No harmful metal mercury.
(7) Color: The current can be changed by changing the color, and the light emitting diode can be easily modified through chemical modification to adjust the energy band structure and bandgap of the material to realize multi-color luminescence of red, yellow, green, blue and orange.
(8) Price: The price of LED is relatively expensive. Compared with incandescent lamps, the price of several LEDs can be equal to the price of an incandescent lamp.
2, LED light-emitting diodes and wafers currently have the ability to produce LED and LED lighting manufacturers are also few, different manufacturers choose different quality of LED is caused by the different price of LED lighting an important reason. Take the red LED as an example, the general use price of common red LED is between 0.03-0.08 yuan, while the price of red LED suitable for producing LED lighting is between 0.12-0.36, and the higher quality is more than 3.2 yuan / only. It is generally not produced. LED lighting LED lighting manufacturers are difficult to distinguish, not to mention consumers. Therefore, it is more ensured that the LED lighting factory that owns the production of LED light-emitting diodes or has complete LED detection equipment is more assured. The basics of LED performance are listed below.
(1) Brightness: The brightness of the LED is not the same and the price is not the same.
(2) Anti-static capacity: The LED with strong anti-static ability has a long life and is therefore expensive. Usually the LED with antistatic capacity greater than 700V can be used for LED lighting.
(3) Wavelength: LED with the same wavelength, the same color, the price is high. Manufacturers without LED spectrophotometers cannot produce color-coded products.
(4) Leakage current: LED is a one-way conductive light, if there is a reverse current, it is called leakage, LED leakage current, short life, low price.
(5) Light-emitting angle: The LEDs of different uses have different light-emitting angles, special light-emitting angles and higher prices.
(6) Lifetime: The key to different qualities is lifespan, which is determined by light decay. Low light decay, long life, long life, and high price.
(7) Wafers: The emitters of LEDs are wafers, and the prices of different wafers vary greatly. The wafer prices in Japan and the United States are relatively high. In general, wafers produced in Taiwan and China are lower than Japan and the United States.
(8) Wafer size: The size of the wafer is represented by the length of the side, and the quality of the large-chip LED is better than that of the small wafer. The price is directly proportional to the size of the wafer.
(9) Colloid: The colloid of ordinary LED is generally epoxy resin, and the LED with anti-ultraviolet rays and fire retardant is more expensive, and high-quality outdoor LED lighting should be resistant to ultraviolet rays and fire.
3, LED lighting design reliability is different, the price of each product will have a different design, suitable for different uses, LED lighting reliability design includes: electrical safety, fire safety, applicable environmental safety, mechanical safety, Health and safety, safe use of time and other factors.
From the perspective of electrical safety, it should comply with relevant international and national standards. Since LED is a new product, China's national standards lag, but the country provides product qualification testing. The price of LED lighting with international safety certification (such as GS, CE, UL, etc.) and national product quality certification is higher because these products are reliable in terms of safety design. Consumers are required to carefully identify the authenticity of the certificate. There are not many manufacturers that have international safety certification and national product certification. From the health aspect, the use of non-toxic material design of the product price is high, especially the indoor LED lighting, do not greedy cheaper use of odor LED lighting, only a few LED manufacturers are using non-toxic materials production, identification method It is possible to use the nose directly and the smelly product is much lower than the odorless one. Similar to lead, mercury, cadmium and other toxins require professional analysis.
From the perspective of applicable environmental safety, there is a reliable dust-proof and moisture-proof design, and the price of LED materials for fire protection, UV protection, and low-temperature cracking is high.
From the point of view of safe use, it is more difficult for the average consumer to differentiate their strengths and weaknesses. The reliability of the design and the merits of the selection of components and components are all related to prices. For engineering lamps, do not choose products with low prices and poor quality. For example, if you use different wires, prices vary. Some manufacturers use disassembled old electronic components to recycle recycled plastics and recycled metal materials to produce LED lighting. These inferior LED lighting prices are more than 50% cheaper than normal LED lighting.
At present, the gap between LED technology in China and foreign countries is not very big, and the chip technology is also getting mature. To sum up, when selecting LED products, blind selection should be avoided, and according to the requirements of the place of use, a foreign or domestic brand LED lamp with a suitable price and quality assurance must be selected.
