With the continuous progress of society and the further maturity of LED technology, LED lights are widely used in our daily life, which has changed the traditional way of lighting to a large extent. Now basically many household lamps have begun to popularize LED lamps, lighting design will more fully reflect the trend of energy saving, health, art and humanization, become the leading room lighting culture. Compared to the past, after several years of development, the price of LED light has fallen to the consumer market, although it is still more expensive than ordinary energy-saving lamps, but because of its unique advantages, such as: LED light life is much longer than energy-saving lamps, it can be used continuously for 100,000 hours, 100 times more than ordinary bulbs; LED lights use only a tenth of the energy of CFLS, etc. So although its price is high, it is still popular.

LED lighting features

LED (light emitting diode) lamp is a kind of lighting lamp made of the fourth generation green light source LED. The light source of LED lamp uses light-emitting diode, which is a new light source technology developed in a new way. It uses semiconductor, so that the power supply can produce light through the semiconductor. LED is known as the fourth generation lighting source or green light source, with energy-saving, environmental protection, long life, small size and other characteristics, can be widely used in a variety of indicators, display, decoration, backlight, general lighting and urban night scene and other fields.

Energy saving: When it comes to LED lights, it must be associated with energy saving. A major feature of LED lights is energy saving, it uses DC drive, ultra-low power consumption (single tube 0.03-0.06 watts), electro-optical power conversion close to 100%, the same lighting effect than the traditional light source energy saving more than 80%. In short, leds are much more energy-efficient than incandescent bulbs, which can save you a lot of money.

Environmental protection: We know that mercury is an extremely toxic substance. However, mercury can be found in almost all of today's high-efficiency electric light sources, whether they are common fluorescent lamps, compact CFLS, or high-pressure mercury and gold halide lamps. And LED lights do not contain mercury elements, waste can be recycled, no pollution. In addition, the light emitted by the LED lamp is soft and not harsh, and does not contain radiation in the light, does not contain ultraviolet light, infrared light, and ordinary incandescent lamp has ultraviolet light and infrared light, permanent will make people's eyes fatigue, bring unhealthy factors to the body. So LED lights can be described as a typical green lighting source.

Longevity: LED light source is known as longevity lamp, meaning that the lamp never goes out. Solid cold light source, epoxy resin encapsulation, no loose part in the lamp body, good seismic performance. There is no filament light burning, thermal deposition, light decay and other shortcomings. The service life can reach 60,000 to 100,000 hours, more than 10 times longer than the traditional light source life.

Multi-color: The color of LED lamps is pure, soft and warm, without doping any color light, and the color is also very diversified, in line with the needs of various decorative styles. LED light source can use the principle of red, green, basket three primary colors, under the control of computer technology to make the three colors with 256 levels of gray and arbitrary mixing, you can produce 256×256×256=16777216 colors, the formation of different light color combination changes, achieve rich and colorful dynamic change effect and a variety of images.

How to choose LED Lights

In the face of many kinds and brands of LED lighting products, how to choose? Inspection and quarantine institutions remind, in the purchase of LED lights should pay attention to the following aspects:

First is luminous efficiency: the higher the luminous efficiency, the more power saving. At present, it is generally recommended to choose LED lamp luminous efficiency [lumen (lm)/ watt (w)] is higher than 80LM/W, this index is in the growth period, the higher the selection value, the more power saving.

The second is the color rendering index: the color rendering index reflects the authenticity of the color after the object is illuminated by the light, the value is 0-100, now the LED bulb color rendering index standard is greater than 75, it is recommended to choose more than 80 is better, people with a studio at home should choose a high display index light bulb, which can reflect the authenticity of the color.

Third is the choice of color temperature: different decoration environment should choose different color temperature LED lights. The color temperature range is 2700~6500K, the smaller the value is inclined to yellow light, on the contrary is inclined to blue and white light, yellow light is usually suitable for winter and bedrooms, living rooms, dining rooms and other occasions, used to create a warm and comfortable feeling. And white light is more bright and clear, suitable for summer and study, kitchen, etc.

Fourth, product quality: an LED lamp is generally composed of three large components: housing components, driving power supply, LED. Because the LED lamp heat is very large, it is recommended to choose the shell with good heat dissipation; In addition, the power factor of the driving power supply should be above 0.9; The LED chip directly determines the brightness and decay of the bead. The so-called penny a good, it is recommended to choose a big brand with warranty LED lights.
