Will LED strip smell of plastic if it is opened for a long time?

LED lamps are absolutely suitable for indoor lighting. No plastic smell.

LED will definitely become the fourth generation of lighting, and the development momentum is getting stronger and stronger. Its main advantages are energy saving, environmental protection, long service life, no stroboscopic, no eye injury and no mosquito attraction. As long as the heat dissipation design of high-power LED lamps is good enough, the service life of 30,000-50,000 hours is no problem (the definition of service life is: LED is a semiconductor component, and its wafer will decay due to temperature. When the luminous flux of LED decreases to 30% of the initial luminous flux due to light attenuation, the LED lamp basically has no meaning of last lighting, that is, life summary. At this time, although the LED lamp can still be lit, the brightness has been seriously reduced, so the heat dissipation of the LED lamp is very important).

You are wrong to say that the object illuminated by LED lights will change color because there is one color missing from the spectrum. Quite simply, a color TV (CRT) is not just a mixture of three primary colors (red, green and blue) to get various colors. There are many high-power white LEDs used for lighting, mainly blue chips to excite phosphors to mix to get white light.

I think you said that the color of the irradiated object will be off color, which is mainly caused by two factors:

1. The color rendering index of the LED used is too low, so that the light cannot reflect the true color of the object. (The color rendering ability of a light source to an object is called color rendering, and the highest color rendering index Ra is 100, which is the best. At present, if the color rendering index of LED reaches 80-85, it is already very good and can be used for indoor lighting.

2. The color temperature of the LED used is not good, which can be considered as the color of light. If the color temperature is low, the light is green and red, and if it is too high, it is blue, which is not suitable for indoor lighting. Therefore, indoor lighting is a very important parameter for the color temperature of LED lamps. LED generally defines the color temperature of 2700K-4000K as warm color, 4000K-5000K as natural white color and 5000K-6700K as positive white color. Warm white and natural white temperatures will give people a warm and sweet feeling, which is suitable for hotels, hotels and bedrooms. White gives a cool feeling and is used for office and living room lighting (fluorescent lamps generally have more color temperatures).

The brightness is equivalent to 100W energy-saving lamp, depending on the light efficiency (lumen/watt, lm/w) of the LED lamp used. For the same wattage, the higher the light efficiency, the higher the brightness. Generally, if the LED lighting efficiency reaches 70lm/w, the brightness of 100W energy-saving lamps can be exceeded as long as it is 50-60W.

In addition, I really haven't seen the brightness of 100W energy-saving lamps for indoor lighting. At least our company does not produce more than 60 W LED indoor.

Finally, you should pay attention to light efficiency, color temperature, color rendering index and light decay when buying LED lamps. The first three are the common parameters of all lamps, and the final light attenuation is the unique property of LED as a semiconductor.
