Secret how to identify the price of LED energy saving lamps
Click:5993 Date:2012-4-18 11:08:07
   LED lighting technology is very energy-saving effect of a lighting technology, the price of energy-saving lamps also inconsistent, what kind of energy-saving lamps is what price? You may not understand, and today we gave everyone Secret
    
LED is less than two to three years time, factory, business, media, all together on the display to the lighting and lighting, LED lighting in the case of no recognized brand, price wars in advance to attack. Almost identical in appearance, structure, function, product, price difference there 2-3 times a lot of users on the one o'clock this get confused, the price difference also is not known, then choose what kind of price of the product, the following V1 advertising lighting to tell!
    
First, the characteristics of the LED light source
    
(1) Voltage: LED low-voltage power supply voltage between 6-24V, varies depending on the product, it is safer than the use of high-voltage power supply power supply, in particular, applies to public places.
    
(2) Performance: energy consumption can reduce the consumption of 80% compared with the same luminous efficiency of incandescent lamps.
    
(3) Applicability: small LED small piece of each unit is 3-5mm square, then there can be fabricated into various shapes of devices and is suitable for the environment variable.
    
(4) Stability: 100,000 hours, the light fades for 50% of the initial.
    
(5) Response Time: incandescent response time of milliseconds, the response time of the LED lights for a nanosecond.
    
(6) environmental pollution: harmful metallic mercury.
    
(7) Color: can change the current color, light emitting diodes by chemical modification methods, adjust the material band structure and band gap, orange red Huanglv Lan multicolor light.
    
(8) Price: LED prices are more expensive than incandescent, prices are pretty price to a few incandescent and an LED lamp.
    
Second, the LED light emitting diode and the chip
    
Also one of the few manufacturers have the capability to produce LED and LED lighting, different manufacturers use different quality of the LED is the price of LED lighting. Red LED, for example, general-purpose ordinary red LED price is between $ 0.03-0.08, while for the production of LED lighting, red LED price between 0.12-0.36, higher quality more than 3.2 yuan /, generally does not produce LED LED LED lighting manufacturers are difficult to distinguish, not to mention consumers. Therefore, the choice of their own production of LED light emitting diode or LED lighting, LED testing equipment has a perfect plant products is thus guaranteed.
    
Below V1 advertising lighting to set out a few basic aspects of the LED performance.
    
(1) brightness: the brightness of the LED is not the same, the price is not the same.
    
(2) antistatic ability: the LED antistatic capacity, long life, and hence the price is high.Usually static than 700V LED can be used for LED lighting.
(3) the same wavelength: wavelength LED, color is the same, the price is high. No the LED spectrophotocolorimeter instrument manufacturers is basically impossible to produce pure colors.
    
(4) Leakage current: LED is a one-way conductive light, if the reverse current is called leakage, the leakage current of the LED, short life, low prices.
    
(5) Viewing angle: the use of different LED light angle is not the same, special illumination angle, and higher prices.
    
(6) Life: the key to quality life, life is determined by the light fades. Light decay, long life, long life and high price.
    
(7) Chip: LED light chip, chip, prices vary widely. Japan, the United States, higher chip prices, the average Chinese Taiwan and the mainland chip prices relatively lower than the United States and other countries.
    
(8) Chip size: the size of the chip to the side of the quality of the chip LED is better than a small chip. Price proportional to the same chip size.
    
Colloid (9): ordinary LED colloid is usually epoxy resin, plus a LED expensive UV and fire retardant, high-quality outdoor LED lighting should be UV and fire.
    
Third, the safety and reliability of LED lighting design, the price will be different
    
The reliability of the design of LED lighting include: electrical safety, fire safety, for environmental safety, mechanical safety, health and safety, safe use of time.
    
From the electrical safety point of view, should comply with the relevant international and national standards. LED is a new product, the Chinese national standards lag, but the national product qualification testing. LED lighting prices with the international safety certification (such as GS, CE, UL and so on) and the national product quality certification must be high, because these products in the security design is reliable. The attention of consumers is to carefully identify the authenticity of the certificate, certificate of international safety certification and the national product manufacturers are not many.From health, the price of non-toxic materials designed to be high, especially in indoor LED lighting, do not cheap selection of LED lighting, odor, currently only a few LED manufacturers is produced using non-toxic materials to identify the method can directly with the nose, the smell of products lower than the odor-free price of a lot. Like lead, mercury, cadmium and other toxins need professionals.
    
From the application of environmental safety point of view, there is a reliable dust-proof design, the high price of materials, fire protection, UV protection, anti-low temperature cracking of LED products.
    
The safe use of time, the average consumer, respectively, the pros and cons is more difficult, the reliability of the design, components choice of the pros and cons of whether or not a great relationship with the price. Works with lamps, do not select the low prices, quality inferior products. For example, selection of wire, the price has a difference. Some manufacturers to disassemble the old electronic components, recycled plastic, recycled metal materials and production of LED lighting, these low-quality LED lighting prices 50% cheaper price than the normal LED lighting.
    
China's LED technology with foreign countries a little gap, but not in the technology becomes more developed, China's energy-saving technologies will be gradually toward the front end. Choice of energy-saving products, do not blindly depend on quality assurance, V1 advertising lighting is paid great attention to technical quality and professional technical staff to maintain
    
In the city's high-rise buildings, vegetation, green, and so have a light show, while we appreciate the possibility to know, how much these are a waste of energy. To promote LED lighting project on the city's night lighting, landscape lighting, roof characters, metal words, neon production and the household must be to promote energy conservation, and use, LED display, LED lighting, etc. .
