LED candle light purchase guide

As more and more LED products enter thousands of households, a variety of LED products are also emerging. There are many times in these products. LED candle lights are a very special kind of lamps, their lights are flames form, and no danger, no harmful substances such as mercury (Hg), will not cause damage to the environment, do not contain infrared, ultraviolet rays, so do not attract insects. Then how do we choose, let's talk about how to choose LED candle light!

1. LED candle light adopts high power and high brightness light source. The product color has 2600K -3200K color temperature and other colors to choose from. The base is made of aluminum alloy, and the surface is oxidized. The special internal ventilation structure design has the advantages of light weight, good heat dissipation and beautiful appearance. The lampshade is made of transparent or opal glass.

2, good heat dissipation, low light decay, efficient power saving. Under the same conditions, the 3WLED candle light is equivalent to the brightness of a 25W incandescent lamp, saving up to 90%. LED high-power candle lamps have a service life of more than 50,000 hours, which is more than 10 times the life of ordinary incandescent lamps, and 1000 hours of attenuation < hourly attenuation < 2%, 40,000 hours of attenuation < 30%. It is to avoid frequent lamp replacement and reduce maintenance management fees.

3. Electrical stability. AC100V -AC240V50/60Hz wide voltage frequency input without flash, fast transient response (delay wide voltage frequency input without flash, fast transient response (delay wide voltage frequency input without flash, fast transient response (delay) No frequent switch damage) No frequent switch damage, it is very suitable for fields with frequent switching times and large voltage fluctuation range.

4, does not contain mercury, lead and other heavy metals that are very polluting to the environment. When it emits light, it produces ultraviolet light, so there are not many mosquitoes around the light source like traditional lamps, which makes the environment more clean and tidy. The efficiency that innovative design of metal shell constant current drive makes the conversion of product energy into light is very high.

Shopping tips

1. Look at the packaging and trademarks. The state mandates that the LED lighting manufacturer's products mark the following contents on the outer packaging: rated voltage, voltage range, rated power, and rated frequency. Generally speaking, the quality of the trademark printing of high-quality products is good, the font is clear, it is not easy to fall off, and it is wiped with a soft damp cloth. The mark is clear and identifiable, it is not easy to wipe off, and there are trademarks of manufacturers and related certification marks. Counterfeit products have poor printing quality, fuzzy fonts, easy to erase, no manufacturer's trademark and related certification marks.

2, LED candle light appearance. A good LED lamp manufacturer is generally a large-scale production product. The shape and size of the LED candle lamp produced are consistent and the product quality is guaranteed. At the same time, there is no crack or looseness in the outer casing, and there should be no traces of being smashed at the sealing position. During the installation and disassembly process, the lamp cap is not loose and the hoe is smashed.

3. The temperature at work. When the LED candle light is in normal working condition, its temperature rise should be very low. Otherwise, the life of the led candle light will be very short. At the same time, when the candle light is on, there is a rapid flashing, or it is very glaring, indicating that the lamp has quality problems.

4, start performance. LED lamp startup has two characteristics: one is that the higher the temperature, the easier it is to start; the other is that the lamp is turned off and will not flash. In addition, it is worth mentioning that many LED lights are very dark, which is not good for the life of the lamp. The LED candle light should be provided with a power circuit and a PCB board inside.

5. See if the link between the lamp and the lamp head is loose. The outer casing of the LED candle light also affects the uniform illumination of the lamp. Generally, the outer casing of the candle lamp is divided into two types, transparent and milky white. After getting the lamp, we first check whether the link between the lamp and the lamp head is loose or not, and the shell has no cracks and looseness, and there should be no traces of the seal at the seal. Then use the baffle to check if the light emitted by the bulb is even on the baffle and if there is a dark spot.
