Home lighting Maintenance for Energy Saving

May 7, 2011 Category :Lighting Wiki 0

Lighting is to create a warm atmosphere, a good helper at home, one to last long and bright, clean light sources to achieve energy savings, should be done:

First, pay attention to regular cleaning lighting. Light cleaning, easy to make the dust accumulation on the lamp, the impact of the output efficiency, it is suggested that at least 3 months a light cleaning.

Second, pay attention to periodic replacement of old lamps. Service life of incandescent lamps and fluorescent tubes in 80%, the output beam of approximately 85% reduction, it should be replaced before the end of life.

Third, ceilings, walls, use light line, to increase light reflection and improve the effect of diffuse light to save power.

Indoor installation of wall lamps, bedside lamps, table lamps, floor lamps, mirror front lamps and other lighting, the height of less than 2.4m and below, light and reliable metal case should be grounded in order to ensure safe operation when the lights in the wiring Box Office should be added a ground wire.

Chandelier cord should be protected at both ends of deduction; both ends of the wires should be lining tin wire (lamp wire) section of not less than 0.4mm2.

Toilet and kitchen equipment Dwarf head, the appropriate use Dwarf ceramic screw caps. Edison screw lamp wiring, phase (switch wire) should be connected to the center contact terminal. Zero line connected to the screw terminals. Lamp such as lamp with a switch to safety, at the beginning of the handle should not have exposed metal parts.

Flat-top installation of various lighting accessories, they should be requirements of lighting installation instructions for installation. Light weight of more than 3kg, the hook should be embedded or directly from the roof fixed hanger bolt installation (can not be topped by hanging lamps hanging keel bracket). Lamp boxes from the wire leads to the lights application hose protection, to prevent exposed wires inside the flat.

Experts advise not to use lights to make frequent switches, as often start in the moment of lighting, the current through the filament is greater than the current normal working hours, making the filament temperature increases dramatically accelerate sublimation, which will greatly reduce its service life Therefore, to minimize the lamp switch.

The safe use of lamps, and extend the life of the lamp? The Council reminded the experts in Fujian Province, in the use of lighting, we should note the following.

First of all, buy lamps, first do not just install the lamp should be carefully read and read the installation manual marking in accordance with the provisions of the instructions to install, use lamps, or they may be dangerous.

Next, click the logo to provide timely replacement of aging light source parameters of the lamp, both ends of that red lamp, lamp black or dark shadows, jump off the lamp, the lamp should be replaced, prevent ballast burn and other insecurity.

Again, in the cleaning and maintenance should be careful not to change the lighting of the structure, and do not easily replace the lamp parts, after the end of the cleaning and maintenance, as is the lighting should be installed, not to leave, the wrong lighting components installed.
Finally, the lamps in use must also strengthen the maintenance, to prolong its life. To note the following specific points: the room lamp should always wipe with a dry cloth, and to guard against moisture intrusion, a long time in order to avoid corrosion damage or leakage occurs the phenomenon of short circuit; installed in the toilet, bathroom lights shall be fitted with damp shade, otherwise it will greatly reduce the service life; installed the lights in the kitchen, special attention should be anti-smoke, because the accumulation of grease will affect the light illumination; a light shade of light transmission is good, but easy to stick ash, should wash the cleaning, so as not to affect the light penetration; lamps if non-metallic, can be used wet wipe, to prevent dust accumulation, prevent lighting effects.

How to Decorate Lighting

Family lamps can be divided into pendant lamps, table lamps, downlights, spotlights, ceiling lamps, floor lamps, fluorescents and other types. The correct choice of light and the proper use of them can change the space environment, and create a comfortable and pleasant home environment.

The lighting design, in conjunction with furniture, furnishings items to consider. If a room is not necessary to highlight the furniture, furnishings, diffuse lighting can be used to make soft light over every corner of the shed; and display art collections in the region, in order to emphasize the focus point of light projection can be used to highlight the theme .

1. The living room need to create an intimate atmosphere, it is best to use a conventional dome light or chandelier lights. Even if the dome light common type is selected, you can also adjust the brightness and bright, to add the indoor atmosphere. Living room lights to be high enough, bright enough to allow light to spread throughout the living room. If the light more, should keep the overall style of coherence. Some of the living room with multiple use capabilities, lighting design is relatively complex and coordinated with the interior decoration, but also consider the activities of family members, according to size and layout of functional areas to effectively light, adjust the illumination. If the living room larger, can be used to solve the regional division of the light, can put a sofa-style floor lamp dimmer, display racks can be installed on a few small spotlights.

2. Entrance: the first gives the impression of entering the room where it was to bright, the living room at the entrance and near the junction with the installation of downlights, spotlights, wall, or installed to improve the situation of poor lighting.

3. Restaurant: hanging lamps should be used to highlight the table, you can use warm chandeliers create a warm dining atmosphere. While also setting the general lighting, the room has a certain brightness, gives the feeling of dry static clean.

Pay Attention to Purchasing Security Lighting

April 29, 2011 Category :Lighting Wiki 0

With the social development and improvement of people’s living standards, people in the lamp lighting system and the overall appearance of the facade also have a deeper effect on higher demand, but in the configuration and installation process it is often overlooked the reliability of its operation and security, thus leaving a lot of hidden dangers.

Therefore, the configuration of the installation of modern lighting, how to make indoor and outdoor lighting and decorative lighting in the break alone, on the basis of the role of beautifying the environment, enhance its security, has become an important part of fire prevention. In a wide variety of lighting fixtures, the more common and larger fire hazard and there are incandescent, fluorescent, high pressure mercury lamps and halogen lamps, such as several following lights.

1. Incandescent: improper cooling, the lamp surface temperatures are high, in contact with combustible, easy to roast burning fuel, and poor seismic incandescent light bulbs fragile, broken glass and heat the filament temperature in the fuel also spilled could easily cause a fire.

2. Fluorescent: the ballast to work, have a certain temperature, such as manufacturing poor, poor conditions or heat lamps and other accessories with the unreasonable failure, the internal temperature can damage the coil insulation strength, the formation of inter-turn short circuit to produce high-temperature baking the surrounding combustible materials.

3. High pressure sodium lamps: capacitors for leakage within the electronic triggers and other factors will generate heat, sealed with epoxy resin loading, heat less volatile, it will cause a fire.

4. Halogen: its high-temperature heat and high temperatures in the outer wall, are easy to ignite combustible materials.

5. Neon: neon-specific transformer high voltage output terminal on the side of the insulation product, such as dust and oil, leakage occurs in wet weather, ignition, so that the transformer power increases, the temperature rose rapidly, easily destroyed.

How to Reduce Maintenance and Energy Costs

April 25, 2011 Category :Lighting Wiki 0

A further measure to reduce energy consumption would be to de-lamp the T8 option from four to three lamps per fixture. This would produce approximately 44maintained foot candles, and decrease energy costs by an additional 10 percent. There would also be additional material and labor savings due to the fewer number of lamps.

Green Lights is an exciting and innovative program sponsored by the US Environmental Protection Agency (EPA) that encourages major US corporations and other organizations to install energy-efficient lighting technologies.

Lights will profit by lowering their electricity bills, improving lighting quality, and increasing worker productivity. They will also reduce the air pollution caused by electricity generation.

Lighting Maintenance is one of a series of documents known collectively as the Lighting Upgrade Manual. All lighting systems experience deterioration of performance during operation and therefore require ongoing maintenance conducted either by properly trained in-house staff or an outsourced lighting management company. As the useful light distributed by the lighting system decreases, wattage remains the same, resulting in waste.

In many buildings, lighting systems are maintained in a reactive rather than a proactive manner. As lamps fail, a service request is registered and the maintenance department can schedule the replacement with its other priorities. Defective components such as failed ballasts and broken lamp holders are only replaced when they cause the fixture to malfunction. And fixtures are rarely cleaned, although dirt and dust buildup is absorbing useful light rather than distributing it.

Considering the waste in labor and energy costs involved, it’s generally advisable to consider a planned lighting maintenance program during the planning of the lighting system.

Planned lighting maintenance is the practice of organizing labor and resources to ensure consistent recommended light levels and the most economical use of the lighting system. It tunes the lighting system and optimizes performance.

How to Reduce Light Loss

April 23, 2011 Category :Lighting Wiki 0

It is possible to evaluate existing and future light loss. The mortality, lumen depreciation, and dirt depreciation curves are used to determine the maintained illumination, which is the average illumination expected over time. An overall light loss factor is applied to initial illumination value to obtain the maintained illumination value. The formula for light loss factor (LLF) follows.

These are three of the recoverable components of light loss that a good maintenance program can minimize. The equation for maintained luminance on horizontal surfaces shows the significant impact these factors have on light levels (see Exhibit 7). These factors are multiplied, typically resulting in lumen output reductions of over 40% in poorly maintained systems.

Although room surface dirt depreciation (RSDD) is a recoverable factor, it is often ignored in lighting calculations and maintenance programs. Since most offices today are smoke-free, the RSDD is minimal relative to the other light loss factors.

Budgeting is the most difficult part of planning a maintenance program. Spot maintenance of a lighting system can be sporadic on a daily basis, but the annual cost will be constant after the first few years. Strategic maintenance, on the other hand, is easier to manage on a daily basis and may cost less overall, but the cost fluctuates each year.

Suppose you want to maintain the fluorescent lighting on a spot basis in a facility that operates 4,000 hours per year. This approach would require replacing about20% of the lamps every year. To maintain the same facility on a group basis would require minimal replacement for two years, and then 100% replacement every third year.

Because budgets are often established a year in advance, it is necessary to predict re-lamp timing and budget accordingly. As an alternative, lighting maintenance budgets can be leveled by completing an equal portion of the group maintenance each year. In the example above, for instance, completing a group re-lamp of 33% of the facility each year will level the annual cost.

Some Tips of Lighting Maintenance

April 21, 2011 Category :Lighting Wiki 0

Proper lighting system maintenance is essential to high quality, efficient lighting. Systematic lighting management methods and services from lighting specialists can help organize the process and assure continued high performance of any lighting system.

Lighting maintenance is more than simply replacing lamps and ballasts when they fail. Facility managers today must manage their lighting resources (i.e., fixtures, lamp/ballast inventory, labor, energy) to sustain the quality of a lighting system.

The light output of a luminary decreases with age and use, yet the energy input remains unchanged. Because the human eye is extremely adaptive to gradually changing lighting conditions, most occupants do not notice the gradual decline in light levels. Eventually, however, the reduction will affect the appearance of the space and the productivity and safety of the occupants.

In the past, lighting designers have dealt with this problem by increasing the number of fixtures or lamps to compensate for the future light loss. While this simplifies maintenance, it is not an acceptable solution due to the added initial equipment cost, energy cost, and energy-related pollution.

Three factors cause light loss—— lamp and ballast failure, lamp lumen depreciation, and  luminary dirt depreciation. Light loss gradually decreases system efficiency over time. In combination, these factors commonly reduce light output by 20-60%. No corresponding energy reduction is associated with light loss, except with lamp and ballast failure.

When lamps and ballasts fail, they no longer provide light for the space. Often, failed lamps and ballasts remain in fixtures for months. Lamp manufacturers list the “average rated life” for their products. The average rated life is the number of operating hours after which one-half of the lamps can be expected to have failed. A few lamps may fail soon after installation, and the rate of failure will increase as the time in use increases.

How to Maintain Long Lives of Lamps

LED Lights have been Questioned

April 16, 2011 Category :Commercial Lighting 0

In the field of the Led industry, many people seem to have seen a bright future. It is expected as early as in 2015, LED lighting market in China will reach 20% of the global market shares, contributing to the industrial scale up to 5000 billion yuan, and China LED lighting market will enter the global top three.

May 2009, Ministry of Science and Organization through the application of LED lighting in the municipal demonstration projects as the carrier, select the 10 cities, each city promote the use of LED lighting features more than 10,000, the scheme known as the “city of ten thousand ten” . Since then the city to join the growing number of the plan, but now, LED lights have heard many voices of doubt the promotion.

Clearly, the Guangzhou Asian Games will push the peak LED. For a time, “green”, “energy saves”, “high tech” and other words of praise, almost as a synonym for LED, shining everywhere LED light.

“Since last year, the domestic market suddenly abnormal LED optimistic merger integration investments at home and abroad to accelerate the process upstream and downstream enterprises, state-owned capital, private capital, also have entered.” At the recent press conference in Guangzhou International Lighting Exhibition, and a people in the quietly said: “The traditional lighting companies recognize this is a treasure not been fully developed, for a time all kinds of LED lighting products flooding the market.”

This is the second issued by Ministry of Science, 2009 “Ten City, ten thousand” LED after another round of investment fashion. 2 years ago, according to the plan, “Ten City, ten thousand,” Application of semiconductor lighting project objectives are: to 2011 in the pilot cities for the Municipal Works 6 million LED lighting products, directly stimulate domestic demand 15.0 billion; to 2015, LED into 30% of the general lighting market. In fact, the country now and not just “Ten City”, according to data from the end of 2010, now has, including 42 cities, including Guangzhou, included in the plan.

“If you ask me the same question now, I still hold the same view — promotion of LED lamps must be careful, not hot-headed!” Open to pour cold water on LED lights, and deputies from the China Southern Power Grid Xin Pu, challenged during the two sessions, he once again reiterated to reporters “can not be hurried.”
