What kinds of LED lights are there?

In recent years, with the increasing awareness of healthy lighting, more and more people begin to pay attention to and buy healthy LED lights. But in the face of a variety of LED lights on the market, how to choose? How to choose? This has also become a headache for many consumers. What's the difference between an energy-saving lamp and a LED lamp? What kinds of LED lights are there? What are the shopping tips for LED lighting?

First, data speak.

National LED lamp quality testing is under way, but the testing data is worrying, the qualified rate is only between 50% and 75%. Energy-saving LED lamp quality fails, consumers in the replacement of commodities, may wreck commodities lead to electric shock accident, do not let the tragedy brew.

Two. Introduction of LED

There are many kinds of outdoor lighting LED, which are different in shape, color, brightness, power and so on. On the one hand, it brings more choices to consumers, but on the other hand, it also increases the complexity of LED classification. The classification of the application scope of general LED is summarized as follows:

1. Outdoor landscape lighting

Guardrail lights, projection lights, LED lamp strips, LED profiled lights, digital lights, buried lights, lawn lights, underwater lights, etc., have a market share of several billion yuan, with a potential market of tens of billion yuan.

2, indoor lighting

Wall lamp, chandelier, embedded lamp, spotlight, corner lamp, flat panel, grille lamp, fluorescent lamp, barrel lamp, slideshow and so on, have a market share of more than one billion yuan and a potential market of tens of billion yuan.

3. Private lighting

Portable lighting (flashlights, headlights), low illumination (corridor lights, door signs, courtyard lights), reading lights, microscope lights, projection lights, camera flashes, desk lights, street lights, etc., have a market share of several billion yuan, with a potential market of tens of billion yuan.

4, safety lighting

Mine lamp, explosion-proof lamp, emergency lamp and safety indicator lamp have a market share of several hundred million yuan and potential market of several billion yuan.

5. Special lighting

Military illumination lamps, medical non-thermal radiation lamps, therapeutic lamps, sterilization lamps, special illumination lamps for crops and flowers, bio-special lamps, special LED lamps combined with solar photovoltaic cells, etc., have a small market share, but have great significance and importance. The potential market is tens of billions of dollars.

Three, the difference between energy saving lamp and LED lamp.

Comparison of energy saving

LED power consumption is very low, generally speaking, the working voltage of LED is 2-3.6V. The working current is 0.02-0.03A. That is to say, it does not consume more than 0.1W of electricity. The power consumption of LED lamps is 1/4 of energy-saving lamps. Comparison of energy saving

Comparison of heat dissipation

Comparing the heat dissipation 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 ordinary energy-saving lamp is really good, which is the shortcoming of the LED lamp. But now manufacturers are overcoming such defects as led, the development of radiator is also under way.

Health comparison

LED lamps do not contain harmful elements such as mercury and xenon, conducive to recovery and do not produce electromagnetic interference (ordinary lamps contain elements such as mercury and lead, electronic ballasts in energy-saving lamps will produce electromagnetic interference).

Life comparison

The service life of the ordinary energy-saving lamp can reach 10,000 hours, and the LED lamp has a longer service life, up to 100,000 hours, because of the different way of lighting and the ordinary energy-saving lamp, the LED lamp has a much longer service life than the ordinary energy-saving lamp.
