With the enhancement of people’s awareness of environmental protection, more and more people are beginning to pay attention to and buy LED lights.
But in the face of the variety of LED lights on the market, how to choose has become a headache for many consumers. What is the difference between energy-saving lamps and LED lights,
what kinds of LED lights, and what are the considerations for the purchase of LED lights? This issue of the topic of the editorial for you to answer one by one.
1, Types of LED lights
There are many kinds of LEDs, in shape, color, brightness, power, etc. are different, on the one hand, gives consumers more choices, but on the other hand, it also increases the complexity of the classification of LEDs. In terms of the classification of the general range of applications of LEDs, we outline the following.
Outdoor landscape lighting
Guardrail lights, projection lights, LED strip lights, LED-shaped lights, digital tubes, buried lights, lawn lights, underwater lights, etc.
Wall lights, pendant lights, recessed lights, spotlights, corner lights, flat light-emitting panels, grille lights, fluorescent lights, downlights, variable lights, etc.
Portable lighting (flashlights, headlamps), low-lighting lamps (porch lights, doorway lights, court lights), reading lights, microscope lights, projection lights, camera flashes, table lamps, street lamps, etc.
Mining lamps, explosion-proof lamps, emergency lamps, safety lights, etc.
Military lighting, medical lighting without heat radiation, therapy lights, sterilization lights, special lighting for crops and flowers, special lights for biology, special LED lights combined with solar photovoltaic cells, etc.
2 Difference between energy-saving lamps and LED lamps
LED power consumption is very low, generally speaking, the working voltage of LED is 2-3.6 V.
The working current is 0.02-0.03 A. That is to say: it consumes no more than 0.1 W. The power consumption of LED lights is 1/4 of that of energy-saving lamps.
Heat dissipation comparison
From the heat dissipation comparison between the two lamps, led lights are inferior to ordinary energy-saving lamps,
led lights are not very good for heat dissipation, while the heat dissipation of ordinary energy-saving lamps is really good, which is the drawback of led lamps.
But now the manufacturers are overcoming led such defects, the development of heat sink is also underway.
LED lamps do not contain harmful elements such as mercury and xenon, facilitate recycling and, and will not produce electromagnetic interference
(ordinary lamps contain elements such as mercury and lead, and electronic ballasts in energy-saving lamps will produce electromagnetic interference).
Ordinary energy-saving lamps can reach 10,000 hours of life, and led due to the way of light and ordinary energy-saving lamps are different,
so led lights have a longer life, up to 100,000 hours, led lamp life is much longer than ordinary energy-saving lamps.
3 home space LED lights 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 light wattage requirements are relatively high,
requiring it to ensure that the premise of lighting, so that the living room appears transparent and bright generous is also particularly important.
Bedroom – soft and warm
13-50w, the bedroom light requirements soft, easy to create a warm atmosphere; there should be no harsh light, in order to make it easier to sleep, so the required light wattage is low.
Kitchen – sufficient brightness
3-38w, as people will be in the kitchen for different lengths of time labor, cutting vegetables, and other subtle movements on the lighting requirements are relatively high.
Both to ensure that the kitchen does not leave a dark area, but also to reduce the inconvenience and danger when cooking, so you need to choose a more adequate brightness of the light.
Elderly room – wattage is high
25-100w, the elderly have weakened vision and feel much less light than young people. The elderly need brighter lights to ensure that see things clearly, so you need to choose a high wattage of light.
Children’s room – wattage is low
13-70w, children’s room interior need to choose soft light, room light is too bright will stimulate the eyes and thus affect sleep,
and low brightness of the light is conducive to the development of sleepiness of small children, so choose low wattage of light.
4 factors affecting the price of LED lights
LED brightness is different, the price is different.
2, anti-static ability
LED with strong anti-static ability, long life, and therefore high price. Usually anti-static greater than 700V LED can be used for LED lighting.
LEDs with different uses have different light-emitting angles. Special light-emitting angle, the price is higher. Such as a full diffuse angle, the price is higher.
The key to different quality is life, life is determined by light decay. Light decay is small, long life, long life, high price.
Wavelength consistent LED, color consistent, the price is high. No LED spectrophotometer manufacturers are difficult to produce pure color products.
6, leakage current
LED is a one-way conductive luminous body, if there is a reverse current, it is called leakage, leakage current is large LED, short life, low price.
7, LED chip
LED luminous body for the chip, different chips, the price varies greatly. Japan, the United States of chips are more expensive, Taiwan and China’s local manufacturers of LED chips are less expensive than Japan, the United States.
The size of the chip is expressed in terms of side length, the quality of large-chip LEDs is better than the small chip. Price is proportional to the size of the chip.
Ordinary LED colloid is generally epoxy resin, with anti-UV and fire retardant LED more expensive, high-quality outdoor LED lights should be anti-UV and fire
