Led and energy-saving light which good? To solve the
7, the LED lighting technology is not so mature and complete energy-saving lamp technology. In addition, at present, the led is more expensive than price. Warm color lighting good learning? Different from common understanding, the warm color light source because of its low colour temperature, is not good for students to read or write. 5000 k and 6500 k color temperature (cool color light source) is more popular with the students, more suitable for reading, writing, etc to demand higher visual task. To meet the current criteria of classroom illumination condition, relative to the low temperature, high temperature is more advantageous to delay the visual fatigue of primary and middle school students, improve the efficiency of learning, which is consistent with foreign related research results, using ordinary in the middle and primary schools classroom much for high color temperature of the current situation of the fluorescent lamp is also consistent.
1, energy-saving lamp production process and use waste mercury pollution, the current western countries of mercury pollution is quite seriously. People also more and more realized the dangers of mercury pollution. Led light environmental protection, no mercury harmful substances. The LED assembly parts can be very easy to tear open outfit, no manufacturers recycling can be recycled through other people. 2, because it is energy-saving lamps glass, easily broken, bad, bad installation. The led solid-state encapsulation, belongs to the cold light source type. So it is very easy to transport and install, can be in any tiny and closed equipment, not afraid of vibration, basically don't have to consider heat dissipation
Mercury elements contained within the ordinary energy-saving lamps, bulbs if there is damage will affect the people safety, life expectancy 1 year, met a bad time of year also needs to be replaced, and shape is too beautiful, luminous color and warm color only white. But as a whole solid light, LED bulbs solid cold light source, epoxy resin encapsulation, service life is 5 years, 10 times the energy saving fluorescent bulbs. The installation can guarantee within five years at a time without replacement. Appearance, nobleness and luxuriant and generous. LED bulbs color colorful, such as: white, yellow, blue, etc. Can LED Lantern Festival and environmental protection, shockproof, waterproof, miniature, high brightness, easy to move light, etc.. Gradually along with the global sales plan execution, green lighting industry will rise. LED a new generation of green light source, will be in the 21st century caused a revolution in the field of global illumination. We just need to wait and see
Good long-term considerations must be LED, although the price is high, but long service life, power saving, and environmental protection, long term compared to the ordinary energy-saving lamps province, under the condition of equal brightness LED lamp power is only 1/3 of the ordinary energy-saving lamps. About life equal to 5 times the ordinary lamp.
3, energy-saving lamp power consumption is too large. White LED power consumption is only 1/10 of incandescent lamp, energy-saving lamp of a quarter. 4, energy-saving lamps, easy damage, short service life. Led lights, longevity life can reach more than 100000 hours, can work at high speed. Energy-saving lamps if frequent start or shut off the filament broken will be dark soon. 5, a single LED low power, and energy-saving lamps to achieve the same brightness require multiple parallel. 6, the led light color rendering index is low, under the led light display color no real energy-saving lamps
