LED Grow Lights on The Market

LED grow light can be used for indoor gardening, the bud swells, the leaves push out, the flower forms, and then comes the fruit, including indoor hydroponics and aquatic plants. Although LED plant lights are more widely used in industry, they can also be used in the home.

We all say, there are Chinese, there must be plants, because no matter whether there is fertile soil or ridiculous land, Chinese can plant vegetables by building the greenhouse. As the population increases and the land area decreases, there will be underproduced with conventional farming methods. Therefore, LED grow light have become a necessity of social development.

There are a lot of LED plant grow lights on the market, the spectrum is different, the price is uneven, it is easy to make people feel more confused. Nowadays, more and more online shopping can purchase various monochromatic spectrum such as red spectrum, blue spectrum and green spectrum, even full-spectrum. If you want to produce crops in greenhouse, you will need LED grow lights for enough light, otherwise, it will not grow, even if conditions are very good.

However, the use of LED plant lights also depends on plants growth stages. In general, it is recommended that the plants receive in either "seedling/growth" light cycles of 16 hours of light and 8 hours of dark or "nutritional stage " light cycles of 18 hours of light and 6 hours of dark and the flowering stage receives a half of day to lighting. The different plants and growth stages need different requirements for spectrum. For different plant absorption spectrum, different wavelengths of light should be set. Just like different plants take different time spans to grow up, and different spectrum also take different time spans to bear fruit. If you have requirement, Yaham lighting also has own plant growth laboratory, if you need, Yaham lighting can give the professional advices.

Linear High Bay Lights, For Large-Scale Warehouses, Hub Centers and Ultra-High Ceiling Factories

Large-scale warehouses, hub centers, and ultra-high ceiling factories (≥7 meters) have high requirements for illuminance, beam angle and energy saving of luminaires due to the large area and the high ceiling. In these applications, the general UFO high bay lights are limited by the structure to meet the needs.

Large-scale warehouses usually have a large number of shelves. Only the passages between the shelves and the goods and materials on the shelves need to be illuminated. The narrow and medium light distribution luminaires can focus light in the area that needs to be illuminated, so that light waste can be effectively avoided. LED linear high bay light is very suitable for large-scale warehouses. On one hand, the long and narrow structure adapts to the layout of large warehouses. On the other hand, the narrow and medium light distribution can increase the availability of light. What’s more, LED linear high bay lights are dimmable through intelligent controls and able to respond to the environment around them. Motion sensors could detect exactly when people were entering a particular zone and with the ‘instant on’ nature of the technology, dimmed lights could be brought up to 100% immediately.

Hub centers are busy with heavy work and lots of people. 200lux~300lux ensures that people can work efficiently and safely in a clear environment. Therefore, high-power, high-efficiency luminaires are required to achieve high illumination.

Ultra-high ceiling factories such as aircraft maintenance and repair plant need more than 400W luminaires to meet the demands. The splicable LED linear high bay lights have great flexibility in these applications, and can be adjusted to meet the needs of different heights and illuminations.

More Professional Factory Lighting, Leads To Higher Productivity

Factory lighting not only needs to meet the illumination needs of different industrial sectors, but also guarantees long-lifetime and durability of luminaires, while saving energy. The most important thing is to ensure the efficiency of employees. Appropriate lighting effects not only help to motivate employees, but also prevent the fatigue of employees, maintain the health of employees and prevent work-related accidents. Appropriate lighting effects need to be comprehensively evaluated in terms of visual execution, visual comfort and visual atmosphere.

Assessment Content	Lighting Factors	Impact On Industrial Production
Visual execution	Illuminance and glare	Operating sensitivity and accuracy
Visual comfort	Light Uniformity and CRI	Employees' work comfort, mental concentration and work efficiency
Visual ambience	The direction of the light, the layout of the luminaire and the color temperature	Employees’ mood, attention and safety

In the industrial filed, the ergonomic quality of the workplace is critically dependent on the ease with which various visual tasks can be performed. Good lighting can have a positive impact on other productivity determinants (implementation, mistakes, accidents). In a pleasant indoor environment, a good line of sight and a comfortable feeling can better motivate employees, make them more focused and efficient. In this way, the quality of the work will increase and the number of errors will be significantly reduced. The risk of accidents is also reduced.

Good lighting can lead to higher job satisfaction and thus a positive impact on health: the prevalence is greatly reduced. Good lighting can also produce more fruitful results, not just to maintain health, but also actively promote long-term good attitudes.

On the other hand, factory lighting will vary depending on the operating department and the content of the work. Lighting methods can be divided into: general lighting, local lighting, hybrid lighting and accent lighting.

Lighting method	Definition
General lighting	Uniform illumination set to illuminate the entire location.
Local lighting	Designing a different illuminance for a particular area, such as the place where the work is done, to illuminate the general illumination of the area.
Hybrid lighting	Illumination for a particular visual work to illuminate a part.
Accent lighting	Illumination consisting of general lighting and local lighting.

 Corresponding lighting arrangements for different needs can greatly improve work efficiency and safety while effectively saving energy.

In order to use natural light more efficiently and maximize energy savings at specific times and unmanned states, factory lighting can also be combined with intelligent control modules to control illumination by sensing the illumination of the surrounding environment and the activities of people.

Due to different industries and production environments, the illuminance standards of the factory are also different, and there are different requirements for luminaires.

1. The general industrial environment is 100~500 lux, and the precision manufacturing environment is generally 500~1000 lux. In the electrical engineering industry, inspection and measurement operations require 1500 lux illumination to ensure safe and accurate operation.

2. Heavy industry generally requires luminaires with high protection level (IP65 and above), explosion-proof and high temperature resistance and corrosion resistance.

3. The printing industry requires CRI>90.

4. The food processing industry requires CRI>80 and ISF certification.

5.Plastic processing, wood products manufacturing, chemical industry are required to have explosion-proof characteristics.

For factory lighting, only the illuminance standard value is not perfect, and vertical illumination, illuminance uniformity and brightness balance should be fully considered according to the characteristics of the actual operation.

• Vertical illumination

The illuminance values specified by the standard are mostly horizontal illuminance. In industrial production, many visual tasks are performed on the vertical (tilted) surface, so not only the horizontal illuminance (Eh) of the working surface but also the vertical illuminance (Ev) is guaranteed. In general, the ideal Ev/Eh ratio is 1:3; and when the visual task is mainly completed in the vertical plane, the ratio of Ev/Eh is preferably 1:1 or more. An effective way to increase the vertical illumination is to add local illumination to the vertical work surface, it is also possible to use a wide light distribution luminaire in general lighting because it provides better vertical illumination.

• Illumination uniformity

This is an important indicator for improving visual satisfaction and reducing eye fatigue. The national standard clearly stipulates that the general illumination illuminance uniformity in the working area should not be less than 0.7, and the uniformity of illumination around the working surface should not be less than 0.5. The illuminance value of the general illumination of the channel and non-working area should not be lower than 1/3 of the general illumination illuminance value of the working area. An effective way to improve the uniformity of illumination is to correctly select the light distribution of the luminaire. For the general illumination of most standard buildings, such as large equipment without large scale, the proper choice of wide light distribution is the most convenient and effective choice.

• Brightness balance

The ultimate goal of improving the uniformity of illumination is to achieve a good balance of brightness, the illumination is perceived by the human eye as the reflection of the surface of each substance in the work area, that is, brightness.

Under the balanced brightness, the human eye feels comfortable and does not fatigue due to the constant adjustment of the pupil. On the other hand, the resolution of the details of the working object requires a strong contrast of brightness between the details and the background. Therefore, adjusting and selecting the brightness contrast of the field of view for special job requirements is a problem that factory lighting needs to solve in depth.

Choosing the right luminaire for different industry needs can effectively ensure work efficiency and safety.
