In recent years, as the permeability of LED Grow Lights increase, the output value of the global LED Grow Lights has began to rapidly grow in 2013, although the scale of the output value is only ten million U.S. dollars, but which is expect to exceed $ 35 million in 2014 and challenge more $ 300 million in 2017.

With the acceleration of urban construction, more and more mountain are connected by the tunnel , we have been concerned about how to choose a good tunnel lighting, as the tunnel is semi-closed environment, we must choose the lamp which can properly light up the tunnel and come through the fog and have the features of the strong waterproof and rustproof ,the high-pressure sodium lamps is currently the most widely used, but with increasing demands on energy saving, plus that the light colour of the high pressure sodium and mercury lamp is narrow, the brightness is low, we begin to turn to LED tunnel lights, so, what is the difference between the LED tunnel lights and high pressure sodium in the end?

1, just from the luminous efficiency, the LED tunnel light is 90lm / w,the sodium light reach 120lm / w;

2, from the performance of through the fog, the golden yellow light of the sodium light can better through the fog, of course, which can also be replaced with warm white LED tunnel light;

3, in view of the initial investment cost, the price of the LED tunnel light is three to four times more than the sodium light;

4, as far as the saving the cost is concerned, taking into account the factors such as the power , LED lights can save more than 60 percent;

5, long life, LED tunnel lights can theoretically reach 50,000 hours or more, but limited by a variety of factors, such as lamps heat dissipation, the life of the power and so on, the life of the sodium lamp can reach 12,000 hours, considering the high cost of maintenance in the tunnel, the LED tunnel lighting is more appropriate;

Generally speaking, 100W LED lighting can completely replace 200W high pressure sodium (the specification of the sodium light is typically 250W), but we should choose the right products from the color temperature, light efficiency, heat dissipation, etc., in addition to a large number of products must be used for the project, we can make a relatively detailed investment plan to contrast,after the initial investment of the product, energy-saving performance and maintenance costs are analyzed. LED tunnel lights is better than the high sodium sodium light.

Shenzhen Lead Opto-Technology Co. Ltd is a professional manufacturer of LED lighting, mainly produce LED High Bay Light, LED Flood Light, LED Panel,LED Ceiling Light etc with OEM&ODM service.

The choices of factory lighting plague many people, then which kind of plant and height and area of the plant and lighting is the most reasonable in the end? The lighting expert will tell you: how to choose and design the preferable factory lighting?

1 choice for the lighting way

(1) For the illumination requirements that is higher and the working position which is not of high density, the mixed lighting should be adopted a place where it is unreasonable to separately adopt the general lighting

(2) less demanding on the illuminance, when subjected to the technical conditions of production constraints, which is not suitable for installation of local lighting, or unreasonable use of mixed lighting, general lighting should be used alone.

(3) the partitioned general lighting can be adopted in work area where the lighting illuminance needed is more than the general.

(4) When the district illumination can not meet requirements for general illumination ,the local lighting should be added.

(5) the partial lighting shouldn’t only be installed in the work area.

2. illumination standards

The illuminance values of the factory lighting design should be based on the national standard GB 50034 – 2004 “architectural lighting design standards” requirement to select. This standard specifies the illuminance values of the general lighting of 16 Congress of industrial building. More specific illumination standards of all kinds of factories workplace shall also be relevant industry regulations.

3. Lighting quality

Lighting quality is the flag that measure the quality of factory lighting design. It mainly includes the following:

(1) select the lamps whose efficiency is high and the light distribution curve fit. According to the rate of Index feet of the height of hanging lamps in the plant room shelf is to select the different light fixtures.

When RI = 0.5 ~ 0.8, should use narrow light fixtures;

When RI = 0.8 ~ 1.65, the appropriate selection is light fixtures;

When RI = 1.65 ~ 5, should use width light fixtures.

(2) select the appropriate color temperature and the lighting source whose color rendering index meet the production requirements.

(3) achieve the required uniformity of illumination: general lighting illumination uniformity of the operating area should not be less than 0.7,illumination uniformity of adjacent to the surrounding of the operating area shall not less than 0.5.

(4) meet the quality requirements of the directly lighting glare limited: the unified glare rating (UGR) according to the requirements of GB 50034-2004,which is that the generally allowed rate is 22, fine processing rate is 19.

(5) take measures to reduce the voltage fluctuations, prevent the lighting effects of voltage flicker and stroboscopic effect.

(6) lighting device shall be operating within the allowable voltage, the compensation capacitor should be used to improve the power factor where the metal halide lamps and high pressure sodium is used.

4 Industrial lighting options

How to choose the light should be based on the characteristics and requirements of production process. The LED tube light and LED high bay light should be adopted in the office and in the workshop,the metal halide lamps can be used where the height of plant is higher (6m above), the high pressure sodium lamps should be used where there is no requirements on color index.

Nowadays,the LED flood light and LED tube light is most widely used as the representatives of the decorative lighting and the home lighting in daily life,the LED tube light enjoys a great popularity in our corridor, restaurants, shopping, leisure and entertainment, galleries, exhibition halls and other indoor environments everywhere, the LED flood light is mainly used in city squares, parks, stadiums, the facades of large commercial buildings and hotel, stage, waiting rooms, airports etc. where the higher brightness is needed to illuminate,meanwhile,there a large number of factory engaging in developing and producing the LED light,Lead Lighting is just one of them,which adopts high brightness SMD as the light source of the LED tube and highly integrated and high brightness COB as the light source of the LED flood light so that fully guaranteed stabe and soft light of the LED tube light and octahedron breadth and brightness irradiation range of the LED flood light, while low voltage constant current driver ensure the AC can be converted into the DC to improve energy efficiency of the LED tube light and LED flood light and reduce the waste heat energy and stroboscopic effect exciting the human eye, the most important is that the LED lighting without adding mercury and other heavy metals harmful to our body and pollution the environment, that’s why the LED light is Known as energy-saving and environmental protection ,login http://www.ledclan.com to learn more features and uses of the LED tube light and surf www.lead-lighting.com to know more awesome LED floodlights and other LED lighting.
