Household led lighting knowledge analysis

As LED lighting fixtures begin to enter the era of the whole people, more and more consumers hope to have a sufficient understanding of the knowledge of household LED lighting fixtures. Today, let's take a look at the knowledge analysis of household led lighting fixtures for your reference.

LED lighting knowledge-basic knowledge

LED semiconductor light-emitting devices include semiconductor light-emitting diodes (LED for short), digital tubes, symbol tubes, rice-shaped tubes and dot-matrix displays (matrix tubes for short). In fact, each light-emitting unit in the digital tube, symbol tube, meter tube and matrix tube is a light-emitting diode.

knowledge of led lighting -- characteristics of led light source

1. Less power consumption: LED with a luminous efficiency of 75Lm/W is 80% less than incandescent lamp with equal brightness;

2, long life: the product life of up to 50000h,24 hours of continuous lighting can be used for 7 years;

The nanosecond response speed makes the dynamic control of brightness and color easier, and can realize the dynamic change of color and digital control;

4. Large design space: it can be organically integrated with the building to achieve the effect of seeing only light but not lights.

5, environmental protection: no harmful metal mercury, no infrared and ultraviolet radiation.

6, color: different wavelengths produce different color light, bright saturation, no filter, available red, green, blue three primary color control after the formation of different colors, and can achieve full color, gradient and other color effects.

Led lighting knowledge-led features:

LED lighting is a green light source: low working voltage, low power consumption; stable performance, long life (usually 100000 hours), short response time, no pollution to the environment. Although more expensive than existing lighting fixtures, it is still considered that it will inevitably replace existing lighting devices.

Knowledge of led lighting fixtures-an important reference for selecting led lights

1. There should be no ultraviolet and infrared light in the spectral components. Long-term excessive acceptance of ultraviolet rays, not only easy to cause keratitis, but also on the lens, retina, choroid and other damage. Infrared rays are easily absorbed by water, and excessive infrared rays are absorbed in large quantities when the lens of the human eye is gathered. Over time, the lens will undergo degeneration, resulting in cataracts.

The color temperature of the light should be close to natural light. People live under natural light for a long time, and the human eye has strong adaptability to natural light and good visual effect.

3, no electromagnetic radiation, put an end to radiation pollution to protect the brain. It can not only provide a comfortable light space, but also meet the physical health needs of people, and is an environmentally friendly healthy light source. Long-term use can protect eyesight and prevent myopia.

4, zero stroboscopic, will not make the eyes fatigue phenomenon. The power supply frequency of ordinary fluorescent lamp is 50Hz, which means that it is bright and dark 100 times per second when it emits light. It is a low-frequency stroboscopic light, which will make the adjustment organs of the human eye in a tense adjustment state, resulting in visual fatigue. If the frequency of light is increased to hundreds or tens of thousands of hertz or more-to become a high frequency, the human eye will not have a stroboscopic feeling; but the real stroboscopic is DC power supply or semiconductor solid-state light-emitting devices (such as LED light-emitting diodes) The light emitted is called stroboscopic light.
