LED high bay lights, a general term of all the LED luminaires that are used in factories, mines, warehouses, and high-tent working areas. In addition to all the standard kinds of industrial lighting fixtures used for standard environment, there are also explosion proof high bay lighting and anti-corrosion led high bay fixtures for special environments.
LED lighting VS Traditional lighting
According to different light sources, high bay lights can be divided into conventional high bay lights (like sodium lamp high bay and mercury lamp high bay) and LED high bay lights. Compared with conventional lighting, LED high bay lighting fixtures have many advantages.
-
LED high bay lights have higher RA. RA>70
- LED high bay lights have higher light efficiency and are more energy-saving. For example, one 150w high bay LED lighting can be a direct replacement of 400w conventional high bay lighting.
- Conventional light sources all have features and responses of high fixture temperature. The temperature can reach 200-300℃. However LED itself is a cold light source, so the fixture has low temperature, and it’s safer. It belongs to cold drive.
- LED high bay lights are under continuous innovation. The newest-style fin radiator make LED high bay lights have more reasonable radiator design. This decreases a lot of weight of LED high bay lights. The weight of 80W LED high bay light drops to below 4KG, and can perfectly solve the heat dissipation problem of conventional 300W LED high bay lights.
According to lighting functions, LED highbay light can be divided into two kinds, general lighting fixtures and partial lighting fixtures.
General lighting fixtures
General lighting fixtures are usually installed uniformly on top or side walls of working places to lit up the whole places. High power and energy efficient warehouse lighting fixtures are necessarily required. The vast majority of led bay light fixtures belong to this type. General lighting fixtures have higher requirements for light distribution. They widely adopt direct lighting and semi-direct lighting, especially the latter. Part of the upward lights of semi-direct lighting illuminate the ceiling. This can increase ceiling brightness and create more comfortable and brighter environment.
Usually when we are designing energy saving warehouse lighting solutions, we are looking for LED light bay lighting fixtures, or LED barn lights.
Partial lighting fixtures
Partial lighting fixture is a kind of luminaire that aims to improve illuminance in a certain working area. Its function is to strengthen and supplement illumination on the base of general lighting. Their light distributions mostly don’t have strict regulations. Partial lighting luminaires are usually installed around working areas. Lighting sources, as used in facility design, should be safe and low voltage. LED warehouse lighting includes portable lighter, pendant lamp, work desk lamp, machine tool working lamp and so on. They are generally installed In some high and big warehouses or working areas. Besides highbay LED lights, sometimes we can also use industrial flood lights as partial lighting.
LED warehouse light usually means LED bay light. It can be LED high bay light and LED low bay light. They all belong to industrial led light. But industrial low bay led light fixtures are not often used now. Usually we need hard lighting for lighting warehouse. Like other LED industrial lights, LED high bay fixtures should also be energy-saving, low-carbon and environment-friendly.
Features of warehouse industrial lighting
1. Meet the requirements of working during nighttime
At night, some laboring is performed in indoor places. Even though in day time some of these areas might still need artificial lighting, which cannot be compared with natural lighting, in the nighttime the lux levels required should be much higher. Lack of illuminance level and visual features will increase error rate or decrease speed, even though adopting higher level illumination to guarantee better visual characteristics.
In terms of visual effects from illumination, lights should be laid out through reasonable lighting calculation according to the corresponding lighting standards and requirements of real working places in order to guarantee minimum lighting level and decrease working efficiency loss, due to insufficient illumination. In dim environment, a certain Color Rendering Index should be guaranteed to improve effective light effects.
2. Make people feel visually comfortable while meeting illumination requirements
The effects that warehouse ceiling and wall sides make to illumination is related to room area. Ceiling in small warehouse accounts for a small ratio and makes few effects to illumination while ceiling in large warehouse accounts for a larger proportion and makes a bigger impact and effect on illumination. Therefore, small warehouse should be equipped with high-reflectivity walls and low-reflectivity ceiling, vice versa for big warehouse to get moderate and uniform illumination through effective lights layout. Illumination requires brightness and clearness, no glaring and no double image.
3. Meeting energy-saving, low-carbon and environmentally-friendly requirements are equally important.
Take conventional sodium lamp for an example, conventional lamps have many disadvantages: low light efficiency, lack of beam reach during the illumination process, poor safety, high energy consumption, low CRI, high thermal efficiency and so on. These cannot save energy well and not eco-friendly. Therefore, best choice for factory and depot ceiling is LED warehouse lighting.
