Development Trend
LED light source is the hope of the 21st century light source market, and many advantages predict that it will gradually replace the traditional light source in the future. Osco pointed out that high-brightness LED will be after Edison invented incandescent light bulb, one of the greatest inventions, energy is a precious resource during the current global energy crisis, so saving energy is a problem we will face in the future.
As a new type of energy-saving and environment-friendly green light source product, LED is bound to be the future development trend.

 

Identification of advantages and disadvantages
LED energy-saving lamps are increasingly welcomed by consumers because of their obvious energy-saving effect, long service life, no stroboscope effect, no noise, soft light and wide working voltage range. However, there are many LED energy-saving lamps in the market, and the quality is mixed. How to buy your own satisfactory products in the wide variety of energy-saving lamps in the lighting shop? The advantages and disadvantages of energy-saving lamps can be identified through "Five Views", which are described as follows.
Look at the packaging and trademark
The state forcibly requires LED lamp manufacturers to mark the following contents on the outer packaging: rated voltage, voltage range, rated power and rated frequency. Generally speaking, the trademark printing quality of high-quality products is good, the font is clear, and it is not easy to fall off. Wipe with a soft damp cloth, the logo is clear and legible, and it is not easy to wipe off. There are trademarks and related certification marks of manufacturers. Fake and inferior products have poor printing quality, vague fonts, easy erasure, and no trademarks and related certification marks of manufacturers.
Second, look at the appearance of LED lamp
The real LED energy-saving lamp uses a three-color tube, which is white and covered by hands. It is whiter. In addition, from the perspective of the lamp tube, multiple lamps can be put together for comparison. The shape and size consistency of the lamp tube are mostly machine bending molding, and most of them are products produced on a large scale. The consistency of the products is good, the quality is easy to be guaranteed, and the interchangeability during maintenance is better. Of course, there should be no cracks, looseness and pry marks between interfaces in appearance. In the process of installation and disassembly, the lamp holder should not be loose, head tilt phenomenon.
Plastic box of the lamp must choose the flame retardant type of engineering plastics. Ordinary plastic is easy to deform and flammable, which is forbidden to be used in the production of energy-saving lamps. The two can be simply identified from the surface, the latter surface is relatively smooth and shiny, and the former surface has a texture similar to matte glass.
Third, look at the working temperature
Under normal working conditions, the temperature rise of LED energy-saving lamps should be very low. Otherwise, the life of LED energy-saving lamps is very short. At the same time, when the energy-saving lamp is lit, it will flash very quickly, or it will be very dazzling, which indicates that the energy-saving lamp has quality problems.
Fourth, see startup performance
LED energy-saving lamps have two characteristics: first, the higher the temperature, the easier it is to start; Second, the lights are turned off and will not flash. In addition, it is worth mentioning that many LED energy-saving lamps are very dark when turned on, which is bad for bulb operating life. LED energy-saving lamps should be equipped with power supply circuits and PCB boards inside them.
Fifth look at the interference situation
In our country, electromagnetic compatibility is already a project that electrical appliances must pass. However, the detection of this project is very complicated. When users buy lamps, they will see if there is a mark on the package that passes the National electromagnetic compatibility test, the second is to bring a medium-short wave radio. When the lamp works, put the radio nearby. The lower the noise emitted by the radio without the medium-short wave radio, the better the electromagnetic compatibility of the tested lamp.

Misunderstanding
LED lighting has become one of the key promotion projects in the world, so it has gradually been accepted by ordinary consumers. It is worth noting that ordinary consumers have some misunderstandings about LED, a new light source:
Misunderstanding 1. Several W LED bulb can replace several W incandescent lamp.
Incandescent lamp usually only talk about wattage rather than lumen, it will affect consumers' habit of buying lamps over time. LED technology is different from incandescent lamp. Due to the continuous development of LED luminous efficiency, wattage cannot represent its lumen number. Some manufacturers give signs similar to "40W incandescent lamp replacement products" on the packaging to help consumers purchase.
In short, W cannot be used to represent the luminous flux of LED bulbs.
Misunderstanding 2. The greater the LED power, the brighter the brightness.
It is generally believed that the greater the power of LED, the greater the luminous flux, represents the brighter the brightness. In fact, this is a wrong understanding, the higher the lm output of LED lamp with different power sizes, the more energy-saving. For example, compared with LED bulbs of 7W and 8W, if the lumen output of 7W is 8W higher, then, the 7W lamp is actually more energy-saving than the 8W lamp.
