Tips for choosing LED lighting products

Page view
The energy-saving effect of LED lighting products has also been recognized by the majority of users. There are also many LED lighting products on the market. As consumers, how do we choose LED lighting products? Below Shanghai Xi Shi will explain some LED lighting products for you. Tips.
 
Look at the spectrum emitted by the lamp for comfort and eye protection:
 
Color rendering is greater than 80, closer to natural light, the color shift of the items under the light is small; according to each person's preference, choose 3000K (warm color temperature), 5000K or more (cold color temperature) or the color temperature between them; use smart phone camera mode, select A flicker-free luminaire (the illuminating image that is observed is water-like and flickering); the wavelength of the luminescence spectrum is constant. The low-cost LED chip can be used for a long time without color drift. It is difficult for manufacturers who do not have LED spectrophotometers to produce pure color products.
 
Look at electrical safety:
 
Usually, the lamp body of the LED bulb is made of aluminum. If the insulation of the driving power source installed in the lamp body has a problem, it is possible to introduce the utility power into the aluminum lamp body, and there is an electric shock when the human hand touches it! There are reports of world-renowned LED bulbs in the European market that "there have been two (such) accident reports, dealers and distributors have taken measures to withdraw from the market." Shanghai Xi Shi uses an insulated ceramic body to make the lamp body, thus eliminating the cause of such electric shock accidents. It is necessary to select the lamps that have passed the necessary safety certification to ensure safe use.
 
Buy a lamp to buy a lumen without buying wattage:
 
Look at lumens (lm, the brighter the light source, the greater the number of lumens). Buying a lamp is an affordable or a waste. The advent of LED lamps has changed the pursuit of buying lighting. If you still look at the wattage to buy a light bulb, you have to be OUT. Assuming a 30 square meter living room with a required luminous flux of 3000 lm, consumers can purchase 200W incandescent lamps, or 50W fluorescent lamps, or 43W low-efficiency LED lamps, or 27W high-efficiency LED lamps. Although the wattage is different, their final lighting effects are similar. If you choose a low wattage LED light under the same lumen parameters, congratulations, this wise choice saves more than 37% of the electricity bill at home. In this way, with lumens as the parameter standard and then reference to the wattage comparison, you can always buy high-efficiency, energy-saving and economical lamps! The luminous efficacy of the bulbs manufactured by Shanghai Xishi has reached 110lm/W or more.
 
See if the service life is long enough:
 
The life of LED chips is generally more than 100,000 hours, but why is the service life of general LED lamps sold on the market only 10,000 to 20,000 hours? This depends mainly on the life of electrolytic capacitors in the driving power of LED lamps. The drive power of Shanghai Xishi 3W and 5W bulbs replaced electrolytic capacitors with long-life capacitors. Although the cost has been greatly improved, the service life of the whole lamp has been increased to more than 35,000 hours. The service life of an LED luminaire is not terminated by a point that is not bright, but is based on the period during which the luminous flux is maintained at 70% or more. The LED bulb manufactured by Shanghai Xishi has undergone accelerated test test in the temperature environment of nearly 60 °C by domestic authoritative departments, creating an excellent record of 2500 hours of illumination to maintain the luminous flux attenuation better than 2%. It depends on the selection of high quality imported chips and excellent heat dissipation. The chip has low light decay, long life, long life and high price. The chips in Japan and the United States are more expensive. Generally, the prices of chips in Taiwan and China are lower than those in Japan and the United States.
