The classroom design should use what kind of lamp?
Many places still choose to use the traditional fluorescent lamp, fluorescent lamp because of the shortcomings, is will be washed out after all, LED is the mainstream of the future, then where is the classroom use of the advantages of LED lamps and lanterns?
1.
Light utilization and the high efficiency of lamps and lanterns of traditional fluorescent lamp is illuminated in the glowing cylinder, this feature for installation at the top of the indoor lamps and lanterns below is a big shortcoming.
Because fluorescent tube light is less than 40% directly according to the working face, and around 60% of the light is through the reflector lamps and lanterns arrives after the reflection of working face, good reflector lamps and lanterns in general, only 70% of the reflection efficiency.
The efficient tricolor fluorescent tube lights about 105 lm/W, and high efficient electronic ballast loss, efficiency is about 95 lm/W, after load the lamps and lanterns, the total efficiency of lamps and lanterns is 72 lm/W only.
However, the existing high efficiency LED lamps and lanterns is very comfortable in the output of light (
Color temperature 4000 k color the sun;

10)
, the comprehensive efficiency of lamps and lanterns can reach 95 lm/W ~ 100 lm/W, that is to say, the LED lamps and lanterns under ensure light comfortable future, because of its high luminous efficiency and a direction glow of light utilization rate is high, so the efficiency of lamps and lanterns has significantly more than the traditional trichromatic fluorescent lamps and lanterns.
2.
The blackboard lamp illumination uniformity can meet the requirements for middle and primary school classroom, the width of the board is already determined,
Single piece of about 2 meters)
, the length of the traditional fluorescent tube is according to the international standard fixed, for example (
32W/36W)
The luminous body length of 1.
2 meters, 58 w luminous body length is 1.
5 meters.
With the traditional fluorescent lamps and lanterns on the blackboard, with two T832W / 36 w lamps and lanterns, because restricted by tube length, degree and intensity of illumination uniformity of the blackboard is far short of GB50034 -
Or DB31/539-2013
2011 request, to make a 2 T858W lamps and lanterns, degree of evenness indexes have markedly improved, but there are still a large proportion of unqualified, and the indicators of energy efficiency, the power density of the classroom and often amounted to less than 9 w/m2 parameter values.
Unit, where the author measured throughout the country more than 500 classrooms, with the traditional fluorescent lamp of the blackboard evenness project qualification rate of less than 20%.
LED lights for the light source and light distribution can be any shape and precise, so can do on the premise of guarantee has met the requirement of the power density, meet the requirements of illumination and the intensity of illumination uniformity of the blackboard.
3.
Long service life and low maintenance costs of the service life of lamps and lanterns and maintenance costs to the national level is related to energy conservation and emissions reduction and the overall situation of constructing economical society, because of the shorter service life will mean a growing number of tubes production process energy consumption and pollution.
To use the unit is related to the use of maintenance resources and manpower costs.
The service life of the traditional fluorescent lamps and lanterns, although there is a lamp claims of (
8000 ~ 10000)
Hours, but as a result of the ballast indicators, while maintaining the service life of more than 70% when the light output is only (
6000 ~ 7000)
Hours, and each year the basic need to change a light tube.
And LED lamps and lanterns is in keeping the light output more than 70% under the premise of service life can reach (
40000 ~ 50000)
Hours, can be realized only in once for five years.
Now LED the cost than traditional
led lighting lamps and lanterns of lamps and lanterns, also is only 1.
1 ~ 1.
2 times the price, so the price has very obvious advantages, has been used,
3 ~ 5)
LED project in one of the most obvious feature is integrated maintenance costs only for the use of traditional light source of lamps and lanterns is about 20%.
LED lamps and lanterns with its own unique advantages is sweeping across the industry, from the education of family to business to the classroom design, LED lamps and lanterns is ahead of other common lamps and lanterns on the market!
Whenever you grab your remote and turn on the TV, there are numerous ads promoting
led pendant lights and offering for indoor pendant lighting manufacturers extracts, which are said to boost indoor pendant lighting manufacturers.
As manufacturers we are determined to be the very best in led pendant lights, regardless of the size, pedigree or inclinations of our competitors.
comes in a vast array of styles and indoor pendant lighting manufacturers depending on which indoor pendant lighting manufacturersis used.
If our brand is successful and consistent, it will be much easier to initially grab customers and encourage them to purchase led pendant lights further.
