China's National Development and Reform Commission announced that the policy of prohibiting the sale of incandescent bulbs of 100 watts or more on October 1st, 2012, is approaching. LEDinside believes that with the phase-out of incandescent lamps, the relevant LED lighting industry support policies will be further introduced and implemented. It is now a critical period for the transition from traditional lighting to LED lighting, and LED lighting will soon face more rapid development.

In recent years, with the continuous improvement of living standards and increasing attention to topics such as the energy environment, consumer demand for energy-saving, environmental protection, and healthy and comfortable life has become higher and higher. In lighting, the selection of greener, energy-saving, and healthy lighting products has gradually become the mainstream of the society; and LEDs have been widely used as an inevitable trend due to their outstanding performance in energy saving, environmental protection, usage efficiency, and longevity.

According to LEDinside's observation, during the replacement period of incandescent lamps and other lighting sources, consumers are naturally not resistant to LED products, but they dare not accept it. At present, product identification on the LED market is not clear and unclear, and there is also a lack of uniform standards. In the face of jagged products, consumers who use LED technology and even use common sense do not always have a lot of doubts and misunderstandings.

Misunderstanding One, a few W LED bulbs can replace several W incandescent lamps.

Positive solution: Because incandescent lamps usually only speak watts without speaking the number of lumens, it will affect consumers' habit of buying lamps over time. LED technology is different from incandescent lamps. Since the light efficiency of LED is still developing, the wattage does not represent its lumens. Some manufacturers give labels similar to "40W incandescent replacement products" on the packaging to help consumers buy.

Myth #2: The greater the LED power, the brighter the brightness.

Positive solution: The brightness and darkness of general LED light are measured in lumens (lm). The higher the lumen output (lm) of LED lamps with different power levels is, the more energy is saved. For example: 5W and 6W LED bulbs, if the 5W lumen output is higher than 6W, then the 5W lamp is actually more energy-efficient than 6W.

Myth 3: The more LEDs contained in the LED lamp, the brighter the brightness and the higher the price.

Positive solution: Due to the different technologies used in LED chips, the luminous efficiency of a single LED is also very different. At present, LED chips in the mainstream market have many different forms such as high power, medium power, low power, and COB. For example, a mid-power LED with a single lumen output of about 45lm, and a high-power single-lumen that can reach 120lm or more, it is very likely that one LED will have the same luminous effect as the three. In terms of cost, the price of high-power chips is higher than that of medium-power devices. Therefore, the cost-effectiveness of LED lamps is mainly determined by the performance of their selected spare parts.

How consumers choose their own LED products:

1, product packaging two look

(1) Is there a product trademark and certification mark?

For example: 3C certification, CE certification, UL certification, GS certification, etc. In addition, the trademark printing quality of good products is good, wipe with a soft wet cloth, the logo is clear, not easy to wipe off.

(2) Whether the rated voltage, voltage range, color temperature, precautions, safety instructions, applicable environment, etc. of the product are clearly marked

2, product price comparison

Due to special reasons in the production process of LED lamps, the cost is relatively high. General domestic LED lamp prices are more than forty or fifty yuan, and imports are even higher.

3, the appearance of the product

First look at the appearance of the product is not very rough? Is the glue not cleaned, is there a screw protruding the plane? Is the color of the screw consistent with the color of the housing?

4, light inspection

The light after lighting needs to observe the color change of the light carefully. If in a short period of time, from yellow light to white light, or from white light to white light with blue light, such a product would have to be abandoned because of this There are two possible conditions: one: power problems; two: LED light source selection errors. In addition, the color of the light must be positive, and the light color of the light is the same, ie it does not flash. After the LED lamp is turned on, it can detect the heat dissipation of the product by touching the surface temperature of the product. If the temperature of the product surface continues to rise in one hour, instead of being stable for the longest time in 30 minutes, the product should not be selected due to heat dissipation. , resulting in shortened product life.
