- From the perspective of electronic appliances: LED table lamps, because the light source is LED. LED is a DC light-emitting device, theoretically speaking. The light emitted is different from the light emitted by our previous generations of light sources. Traditional light sources including energy-saving lamps. Metal halide lamps and incandescent lamps. Are all AC, which will change with the frequency of the input current of the civil power grid. (my country is a 220V, 50HZ power grid), so the frequency fluctuation of AC makes traditional light sources appear frequently. Flashing, working and studying under this kind of light source for a long time will damage the eyes. If you use an LED table lamp, it depends on whether you know how to choose. Not all LED lights have no strobe. If it is a table lamp using a rechargeable battery. The light-emitting panel will not directly see the LED beads without glare. It can protect the eyes. Please note that you must choose the one that is shiny Barcelona LED Discount Code NHS.
- From an optical point of view: when the traditional light source emits light. It will emit light waves of red wavelength at the same time. You can understand it as invisible infrared rays. This kind of radiation with a wavelength above 780nm will cause damage to the eyes. Most myopia is long-term. Indoors, it is caused by excessive reliance on working and studying under traditional lighting. The LED light source is mainly the blue light chip that excites the yellow phosphor powder. The wavelength of the light is between 380-780 nm. There are no ultraviolet and infrared rays. In line with this. The current domestic good ones are all exported) with a color. Rendering index greater than 85 (the higher the color rendering index, the closer to natural light). It has a relatively complete spectrum. that is, it has green light waves at the same time, which is close to natural light, as you know In many cases, the treatment of myopia is to look at green things, because it is necessary to rely on green light waves to repair eye damage, at least it will not aggravate myopia.

What brand of LED lights is good How to choose LED lights
- In recent years, LEDs have been widely used in various households and public places. There are so many brands of LED bulbs, how should we consumers choose? Let’s understand the features and advantages of one of the brands of LED bulbs
- Energy saving: Since LED is a cold light source, semiconductor lighting itself has no pollution to the environment. Compared with incandescent lamps and fluorescent lamps, the power saving efficiency can reach more than 80%. Power consumption is only 1/10 of that of ordinary incandescent lamps and 1/4 of that of fluorescent tubes.
- Healthy: LED lamp brand is a green light source. Compared with incandescent lamps and fluorescent lamps, LED lamps are DC-driven and have no stroboscopic; no radiation pollution, high color rendering and strong luminous directionality; good dimming performance; cold light sources generate low heat and are safe to touch.
- Artistic: color LED products have covered the entire visible spectrum, and have good monochromaticity and high color purity. The combination of red, green and yellow LEDs makes the choice of color and grayscale (16.7 million colors) more flexible .
- Through the above introduction, you should know what brand of LED light is the choice you need, right? I hope that the introduction of the above three points will help you choose LED lights
- LED lamps are one of the most energy-saving lamps on the market after fluorescent lamps. After entering 2013, with the advancement of the market, the sales of LED lamps have gradually increased. Although there are many LED lamp brands in China at present, and the overall strength is also different, there are many high-quality LED lamp brands among them. So, what brand of LED light is good
From four o’Clock
Since LED lamp brands is a cold light source, semiconductor lighting itself has no pollution to the environment. Compared with incandescent lamps and fluorescent lamps, the power saving efficiency can reach more than 80%. Under the same brightness, the power consumption is only 1/10 of that of ordinary incandescent lamps and 1/4 of that of fluorescent tubes. If LEDs are used to replace 50% of our traditional lighting, the electricity saved in our country every year is equivalent to the sum of the power generation of a Three Gorges Power Station, and its energy-saving benefits are very considerable.
- LED lamp brands and is a green light source. LED lights are driven by DC, no stroboscopic; no infrared and ultraviolet components, no radiation pollution, high color rendering and strong luminous directionality; good dimming performance, no visual errors when the color temperature changes; cold light source Low heat and safe to touch; something that incandescent and fluorescent lamps cannot achieve.
- Due to the small power and low brightness of a single LED, it is not suitable to be used alone, but a practical LED lighting fixture designed by assembling multiple LEDs has broad application prospects. Luminaire designers can determine the shape of the optical system of the luminaire, the number of LEDs and the size of the power according to the requirements of the lighting object and luminous flux; they can also combine several LED light-emitting tubes into a point light source, a ring light source or a “secondary light source” of the surface light source. Light source”, according to the combined “secondary light source” to design lamps.
Light color is the basic element of visual aesthetics and an important means to beautify the room. LED lamp brand the selection of light sources directly affects the artistic effect of lighting. LEDs have shown unparalleled advantages in the artistic lighting of light color display lamps; color LED products have covered the entire visible spectrum range, and have good monochromaticity and high color purity. The combination of yellow LEDs makes the choice of color and gray scale (16.7 million colors) more flexible.
Lamps are luminous sculptures, and the material form of lamps constructed by materials, structures, shapes and textures is also an important means of displaying art. LED technology enables room lighting to better organically combine science and artistry, breaking the borders of traditional lighting and beyond the inherent concept of so-called lighting shapes. A new perspective to recognize, understand and express the theme of light. We can more flexibly use the advantages of the combination of light and dark, the combination of light and color, material and structure design in optical technology, improve the design freedom to weaken the lighting function of lamps, make lamps a visual art, and create a comfortable and beautiful lighting art effect. For example, LED lamps made of translucent synthetic materials and aluminum that are similar to candles can be placed on the ground, corners or tables at will. life form Cmple Discount Code NHS
Undoubtedly, the relationship between light and people is an eternal topic, “People see the light, I see the light”, it is this classic sentence that has changed countless designers’ understanding of lights. The highest state of lamps is “shadowless lamp”, which is also the highest embodiment of humanized lighting. There is no trace of common lamps in the room, so that people can feel the light but cannot find the light source, which embodies the humanized design that perfectly combines light with human life.
