With the introduction of LED lighting fixtures into the era of the entire people, more and more consumers want to have sufficient knowledge of home led lighting fixtures . Today, with a small series to see home led lighting knowledge comprehensive analysis, for your reference oh.
Led lighting fixture knowledge - basic knowledge
The LED semiconductor light emitting device includes a semiconductor light emitting diode (abbreviated as LED), a digital tube, a symbol tube, a rice tube, a dot matrix display (abbreviated as a matrix tube), and the like. In fact, each light emitting unit in the digital tube, the symbol tube, the tube and the matrix tube is a light emitting diode.
Led lighting knowledge - led light source features
1, less power consumption: LED light efficiency of 75Lm / W compared to the same brightness incandescent lamp power consumption reduced by 80%;
2, long life: product life of up to 50000h, 24 hours of continuous light available for 7 years;
3, nanosecond response speed, so that the dynamic control of brightness and color easier, can achieve dynamic changes in color and digital control;
4, the design space is large: with the building can be organically integrated to achieve only see the light does not see the effect of lights.
5, environmental protection: no harmful metal mercury, no infrared and ultraviolet radiation.
6, color: different wavelengths produce different colored light, bright saturated, no filter, red, green, blue can be used to control the formation of different colors, and can achieve full-color, gradient and other color effects.
Led lighting knowledge - led features:
LED lighting is a kind of green light source: low working voltage, low power consumption, stable performance, long service life (generally 100,000 hours), short response time, and no pollution to the environment. Although the price is more expensive than existing lighting fixtures, it is still considered to be an inevitable substitute for existing lighting devices.
Led lighting knowledge - the important reference for the selection of led lights
1. There should be no ultraviolet light and infrared light in the spectral components. Excessive exposure to ultraviolet light for a long period of time not only causes keratitis, but also damages the lens, retina, choroid, etc. Infrared light is easily absorbed by water. Excessive infrared light is absorbed in large quantities by the lens of the human eye, and the lens will degenerate over time, resulting in cataract.
2. The color temperature of light should be close to natural light. People live in natural light for a long time. The human eye has strong adaptability to natural light and good visual effects.
3, no electromagnetic radiation, to prevent radiation pollution to protect the brain. It not only provides comfortable lighting space, but also satisfies people's physiological health requirements. It is an environmentally friendly and healthy light source. Long-term use can protect eyesight and prevent myopia.
4, zero strobe, will not make the eyes have fatigue. The frequency of power supply for ordinary fluorescent lamps is 50 Hz, which means that they emit light 100 times per second, which is a low-frequency flash, which can cause the adjustment organs of the human eye to be in a state of intense adjustment, leading to visual fatigue. If the frequency at which light is emitted increases to several hundred or more tens of thousands of Hertz—becomes at a high frequency, the human eye will not have a strobe sensation; but the true strobe-free is a DC power supply or a semiconductor solid light emitting device (such as an LED light emitting diode). ) The emitted light is called a flashless flash.
The relevant information on LED lighting fixtures has been introduced here for everyone. I hope this article will be helpful to everyone. If you still have something you don't understand, you can leave a message to Xiaobian at the bottom. We will answer your questions as soon as possible.
Self-tapping threaded inserts are suitable for creating heavy-duty, wear-resistant and vibration-proof fastenings in materials with low shear strength, such as aluminium, brass, bronze, cast iron or duro and thermoplastics. Threaded inserts with cutting slot are available in steel and stainless-steel versions.
