    LED type introduction


    There are many kinds of LEDs, which are different in shape, color, brightness, power, etc. On the one hand, they bring more choices to consumers, but on the other hand, they increase the complexity of LED classification. For the classification of general LED applications, we summarize the following:


    1. Outdoor landscape lighting


    Guardrail lights, projection lights, LED lights, LED shaped lights, digital lights, buried lights, lawn lights, underwater lights, etc., the current market share of several billion yuan, the potential market has billions of yuan.


    2, indoor lighting


    Wall lamps, chandeliers, recessed lamps, spotlights, corner lights, flat illuminators, grille lights, fluorescent lamps, downlights, changing lights, etc., currently have a market share of more than one billion yuan, and the potential market has billions of yuan.



    3, special lighting


    Portable lighting (flashlights, headlights), low-illumination lamps (lanner lights, house lights, court lights), reading lights, microscope lights, projection lights, camera flashes, table lamps, street lamps, etc., the existing market share is several billion yuan The potential market has several tens of billions of yuan.


    4, safety lighting


    Miner's lamp, explosion-proof lamp, emergency light, safety indicator light, etc., the existing market share of several hundred million yuan, the potential market has several billion yuan.


    5, special lighting


    Military lighting, medical non-thermal radiant lighting, treatment lamps, germicidal lamps, special lamps for crops and flowers, bio-specific lamps, special LED lamps combined with solar photovoltaic cells, etc., currently have a small market share, but have great significance. And the importance of the potential market is tens of billions of yuan.


    The difference between energy-saving lamps and LED lights


    Energy saving comparison


    LED power consumption is very low, generally the operating voltage of the LED is 2-3.6V. The operating current is 0.02-0.03A. This means that it consumes no more than 0.1W. The power consumption of LED lights is 1/4 of that of energy-saving lamps.


    Heat dissipation comparison


    From the heat dissipation comparison of the two lamps, the led lamp is inferior to the ordinary energy-saving lamps, the heat dissipation of the led lamp is not very good, and the heat dissipation of the ordinary energy-saving lamp is indeed good, which is the disadvantage of the led lamp. However, the current manufacturers are overcoming the defects of led, and the development of the radiator is also underway.



    Health comparison


    LED lamps do not contain harmful elements such as mercury and antimony, which are good for recycling and do not cause electromagnetic interference (normal lamps contain elements such as mercury and lead, and electronic ballasts in energy-saving lamps generate electromagnetic interference).


    Life comparison


    The service life of ordinary energy-saving lamps can reach 10,000 hours, and the LEDs have a longer service life than the ordinary energy-saving lamps, so the life of the LED lamps is longer than 100,000 hours. It will be much longer.


    LED light power selection


    Living room


    Bright light


    60-450w, the living room area generally accounts for the main proportion of the total area of the house, so the lighting wattage requirements are relatively high, and it is also important to make the living room appear transparent and bright and generous under the premise of ensuring lighting.


    Bedroom articles


    Soft and warm


    13-50w, the light requirements of the bedroom are soft, easy to create a warm atmosphere; there should be no glare to make people more likely to go to sleep, so the required lighting wattage is low.



    Kitchen articles


    Sufficient brightness


    3-38w, because people work in the kitchen for different lengths of time, the fine movements such as cutting vegetables have higher requirements for lighting. It is necessary to ensure that the kitchen does not leave dark areas, but also to reduce the inconvenience and danger during cooking, so it is necessary to choose a light with sufficient brightness.


    Elderly housing


    High wattage


    25-100w, the old man's vision is weakened, and the light he feels is far less than that of young people. Older people need brighter lighting to ensure that things are seen clearly, so you need to choose a high wattage of light.


    Children's room


    Low wattage


    13-70w, children's room needs to choose soft lighting, room lighting is too bright will stimulate the eyes and affect sleep, and low-brightness lighting is conducive to the development of children's sleepiness, so choose a low wattage of light.


    Affect LED lamp price parameters


    1, brightness


    The brightness of the LEDs is different and the price is different.


    2, antistatic ability


    LEDs with strong antistatic properties have a long life and are therefore expensive. LEDs with an antistatic greater than 700V are usually used for LED lighting.



    3, the angle of illumination


    LEDs with different uses have different illumination angles. Special lighting angle, the price is higher. Such as the full diffusing angle, the price is higher.


    4, life


    The key to different qualities is life, and life is determined by light decay. Low light decay, long life, long life and high price.


    5, wavelength


    LEDs with the same wavelength have the same color and high price. It is difficult for manufacturers without LED spectrophotometers to produce pure color products.


    6, leakage current


    The LED is a unidirectional conductive illuminator. If there is a reverse current, it is called a leakage current, and the LED with a large leakage current has a short life and a low price.



    7, LED chip


    The illuminator of the LED is a chip, and the price of the chip varies greatly. The chips in Japan and the United States are more expensive, and the price of LED chips from Taiwanese and Chinese manufacturers is lower than that of Japan and the United States.


    8, chip size


    The size of the chip is expressed by the side length, and the quality of the large chip LED is better than that of the small chip. The price is proportional to the chip size.


    9, colloid


    The colloid of ordinary LED is generally epoxy resin, and the LED with anti-ultraviolet and fire retardant is more expensive. The high-quality outdoor LED lighting should be resistant to ultraviolet rays and fire.


    6 points to identify the quality of LED lights


    LED lights have a series of features such as obvious power saving effect, long service life, no radiation, no stroboscopic effect, no noise, soft light, wide working voltage range, etc., and are increasingly welcomed by consumers. As a consumer, how to buy a satisfactory product in the LED lamps of the lighting store? How to judge whether the lamp is qualified?


    1, look at solder joints


    The LED strips produced by the regular LED lamp manufacturers are produced by the SMT chip process using solder paste and reflow soldering processes.


    2, look at the quality of FPC


    FPC is divided into copper and rolled copper. The copper foil of the copper plate is convex, and the rolled copper is closely integrated with the FPC.


    3, see cleanliness


    If the LED strips produced by the SMT process are used, the surface is very clean and there are no impurities or stains.



    4, look at the packaging


    Regular LED lights will be packed in anti-static coils and then sealed with anti-static moisture-proof bags.


    5, look at the label


    Regular LED light bags and reel trays have printed labels instead of printed labels.


    6, see attachments


    Regular LED lights will be accompanied by instructions for use and lamp strips in the box, as well as LED light connectors or decks.


    Daily maintenance guide for LED lights


    In the long-term use case, LED lighting fixtures are also worn, and with some wrong operations, it is easy to damage LED lighting fixtures. So how do you use LED lighting to get the most out of it and have a longer life?


    How to clean LED lights


    Care should be taken not to change the structure of the LED lamp during cleaning and maintenance, and do not replace the components of the LED lamp;


    After cleaning and maintenance, the LED lights should be installed as they are, and do not miss or misplace the LED lights.


    Always clean the lamp in the room with a dry cloth and take care to prevent moisture intrusion;


    Lamps installed in the kitchen should pay special attention to anti-smoke, light-colored lampshades have good transparency, and should be diligently wiped.



    LED lamp daily maintenance


    After buying the LED light, you should carefully look at the LED light mark and read the installation and operation manual, and then install and use the LED light according to the instructions, otherwise there may be danger;


    It is found that when the two ends of the lamp are red, the lamp is black or there is a black shadow, and the lamp is not bright, the lamp should be replaced in time to prevent unsafe phenomena such as ballast burnout;


    Do not switch frequently. Because the LED lamp is at the moment of frequent startup, the current through the filament is greater than the current during normal operation, so that the filament temperature rises sharply and accelerates sublimation, thereby greatly reducing its service life.
