Parking LED energy-saving technology program analysis

Underground parking lot lighting, because it is a long continuous lighting, if ordinary LED fluorescent lighting, one lamp beads affected by high temperatures for a long time, decay quickly; Second, in the middle of the night when no one is wasting electricity, so To solve the underground car park lighting, it must be done greatly extend the life of LED lamp, while energy-saving, which must consider the parking lot of the environment, so intelligent. With many years of LED research and development experience, the following analysis of three parking flexible led strip solutions program.

To stick with the pace of the industry's advanced, energy-efficient LED lighting in general parking lot using the human body infrared sensor technology and microwave radar sensor technology and electronic sound and light control sensor technology, due to the shape beautifully designed, stylish, good heat dissipation, high brightness, light uniformity, not glare, and can delay automatic extinguishing human infrared sensor products, has become the best choice for parking.


Features Voice program is to detect ambient sound environment, if the surrounding environment is too noisy, it is easy to have lights; Conversely, if too quiet around, you might not trigger, so it is important to set the sensitivity for the problem, with the sensitivity and adjustable time program, users can set their own sensor sensitivity according to the ambient environment.

Features induction program is to detect human pyroelectric infrared body issued, using Fresnel lenses to collect human infrared energy, an obese person, more infrared energy emitted, whereas the infrared energy emitted by the little man less, Therefore, obese people and skinny people sensing sensitivity, generally sensing distance of 2-4 meters, and someone to fit the occasion. Since the pyroelectric infrared sensor for detecting infrared body, the body's temperature is usually 37.5 degrees, while the temperature near the led tape LED lamp head is generally about 40-45 degrees, so the temperature and fluorescent light interference is relatively large. To address this issue, in particular, has developed a light insulated compartment lamp, can effectively solve the problem of interference of light and heat of the interference. General recommendations, the body is more adapted to the induction fluorescent corridor, if applied to the parking lot, you need to confirm the relationship between environment and people around you. In the first use, CPU cycle time needs to be reset, triggering the start of the second is accurate.

Smart radar sensor is the first program, the main program using the Doppler principle, the microwave transmitting radar signals around 5.8GHz, when a moving object enters into the fields of radar, the feedback signal to the receiving circuit can thus change the trigger circuit working condition. General sensing distance can reach 5 - 9 m, as long as the object moves can trigger. Although its object is triggered in the range, if not move, is still not triggered. Radar sensors can penetrate non-metallic objects, such as gypsum board, wood, etc., especially suitable for concealed installation. The effects of radar interference induced by relatively small, and relatively high sensitivity and is particularly suited to the underground car park led strip light solutions.

Future intelligent LED lighting trend analysis

From investors to architects to plan from senior engineers, process engineers and operators , from wholesalers to retailers worldwide lighting, plating technology, as well as professionals in housing and building automation industries are all being Light + Building attracted .

The author is the greatest feeling than the development of intelligent LED and oled no doubt become the protagonist of the show , which also engaged in the work of the author LED drive power with greater confidence and encouragement. These LED / OLED lighting has a beautiful appearance, comfortable light-emitting surface , the unique structure, intelligent control , ultra-high performance parameters or advanced features , spiral -shaped folding design, etc., and some people even subvert the concept of the traditional lamp and bring a very comfortable and unique lighting environment experience. Compared with traditional lamps , LED lamps not only have environmental protection , energy conservation , safety and other advantages, but also its unique physical properties of solid-state lighting , making the flexible modeling and intelligent control has become more and more designers to pursue . LED / OLED products are unstoppable trend to rapid occupation of the traditional indoor and outdoor lighting markets.

LED lighting industry after years of rapid development, including the replacement market for indoor applications has slowly reached its peak , intelligent LED lighting control is largely Trump .

How to design a suitable office lighting

In addition we have to consider the office feng shui , feng shui taboos office , office Feng Shui , Feng Shui office seating office lighting design should also be considered . Office space can be a complex spatial clusters, is a diverse collection of information conveyed . It usually contains the reception and performance of the corporate image area , open office area, separate office managers , channels and corridors , meeting rooms and informal discussion area. Some large companies also have their own galleries, exhibition space , staff restaurant and lounges . For different types of office design company , in addition to the processing space considerations to be integrated on color and texture than the performance of other materials , plus a good office lighting design . Performance in light of these aspects of language , plays an important role.
We will elaborate three levels in three places during office lighting design to consider:

An office lighting design points:

( A ) a light source with a given 6200K uniformly spaced around the 300-500lx ambient light ( general lighting ) , in each work surface , recommendations given above focus illumination 800lx face with the light of about 4000K .

( 2 ) on the impact of visual acuity , one of the main indicators of the health of the glare index (UGR), should be controlled within 22 of the CRI should reach 80 or more.

( 3 ) other space where you want the light to be bright , dark place should be dark , not averaging flattened . Note that in the meeting room , informal discussions, meeting rooms and other areas , manufacturing and friendly atmosphere with a light warm color ( about 2800-3300K), making interpersonal harmony.

Second, office lighting design considerations :

1 , when the work is difficult to determine the location , the choice of the light-emitting area, low brightness LED lamps, such as LED panel lights. 2 , close to the surface and decorative visual task performance in the room should adopt dull decorative material 3 , office hours almost all day , so the formation of artificial lighting and comfortable lighting environment should be designed in conjunction with natural lighting 4 , at a computer terminal office space equipment should avoid people and what appears on the screen (such as lamps, furniture , windows, etc. ) image 5, the general office lighting should be designed on both sides of the work area , should make using the fluorescent lamps with the longitudinal axis parallel horizontal line of sight should not be arranged in front of the lamp operating position

6 , office lighting should adopt LED lamps.

7 , the ideal office environment and methods to avoid light reflection

8 , the manager's office to consider lighting design desk illumination, illumination meeting space and the necessary electrical equipment

9 , meeting room lighting to consider the lighting for the main parties to the conference table lighting . Engender a feeling of center and focus . Illumination to the right, around the additional auxiliary lighting

10 , in order to meet the main auditorium stage area lighting, ceiling lights can be installed with auxiliary lighting the stage , and to the average vertical illuminance of not less than 300LX

Third, the three errors :

Lighting, space design is undoubtedly the magician . With the improvement of people's quality of life , office lighting design has been more and more attention . In addition to meeting the general lighting needs, the main task is to create a lighting design office of a warm family atmosphere , and therefore , the correct choice of lighting is particularly important. However, due to the general understanding of the lamp is very limited, often blindly use , resulting in a lot of misunderstanding use.

Misuse of a lot of people use blind spot ( ie halogen incandescent light bulbs ) . Spot was originally used for accent lighting , there is emphasis on the role showpiece , but now it is used in general lighting. Spotlights on the ceiling makes the ceiling too eye-catching, but the lighting effects on other objects relative weakening of the illumination range of space has limitations.

Many people misuse two to save money , the choice of a traditional fluorescent lighting , ignoring the traditional fluorescent easily formed in the course of bad light , frequent maintenance .

Many people prefer the misuse of three crystal lamps , think it is a symbol of style , but did not notice the United States and Europe for residential, its ceiling height of at least 3.5 meters, while the domestic residential ceiling height is generally 3 meters or less. Therefore, if you do not consider the situation , blindly use crystal lamps, crystal lamps that not only can not show grace style, but will result in pressure.

Office lighting design is very important, particularly in office buildings, lighting design can affect worker productivity , thus affecting the company's economic development , and even affect the employee's physical and mental health problems mood ! So , for different customer needs, design the lighting in different locations and different requirements , so the rational design and use of lighting to make our office more suitable for work , so that employees better play to their ability , to bring greater benefits , office lighting design is not sloppy !

LED really saving it?

 Prior to this, the lighting industry has never been so beautiful before. Needless to say the industry in energy conservation and environmental protection of the environment and the trend , LED light source has become the mainstream of the future of lighting is an industry consensus , the general trend. Talk of the town even in the consumer market , when it comes to lighting, although most scanty , they are known to everybody LED, which is naturally half thanks to the Government's strong support for the promotion of power, but also the other half of the advantages of LED technology itself and charm due.
The eyes of the general public , as a new lighting technology , LED has basically been equate with saving , the only obstacle seems to be the price . And even in the country , the price is not the problem ( the reason we know everything ) . However , LED energy-saving lamps really do ?

1 , light source efficiency

LED (Light Emitting Diode) is a light-emitting diode, is a computer into visible light can solid-state semiconductor components , like a traditional incandescent and halogen light-emitting principle behind thermal radiation , fluorescent lamps , mercury lamps, sodium lamps and gold halogen lamp is used as the gas discharge principle , LED itself is also a technical representative , a light emitting principle .

Luminous Efficacy : luminous energy into visible light ability , with the ratio of luminous flux and power measured in units of lm / w.

As can be seen from the table , LED technology as a new light source, than traditional lighting technologies have a certain nature . We often speak of LED energy saving is also on this level of judgment , in fact, to determine whether an energy-saving lamps far beyond what technology and light. But even so , the luminous efficiency of a wide range of LED technology , the general said LED light source is also more energy efficient than other light sources is not accurate , it is like saying people are romantic, Chinese people are industrious, the Japanese have behaved the same, do not science. We get along , I have to see each other is how a specific French, Chinese and Japanese , but also with LED products as well.

2, electrical energy efficiency

In addition to the line voltage incandescent and halogen lamps , light sources are needed with other lighting appliances . Electrical lighting power utilization is also problematic , namely the use of electrical energy from the power line drive in the ratio of light source used in the case without considering harmonics , power factor λ is usually cosφ to represent. These do not understand it does not matter , in short , the efficiency of lighting appliances usually need to see the power factor indicators on the right.

Most brands will provide electrical products like books or on the efficiency of the system parameters of a single page , as shown below, our designers can require manufacturers to provide relevant parameters.

3 , lighting efficiency

Lighting efficiency is better understood, simple terms is the ratio of the light fixtures inside out under standard conditions of light out of the light , usually expressed LOR , LOR = luminous flux emitted by the lamp / luminaire light flux. For example, a normal 3 * 14W lamp panel , a light source is the total luminous flux 3600lm, if the measured lamp luminous flux is out of 1800lm, we say that the lamp efficiency is 50%.

4 , energy-efficient lighting

If lamps with light and practical method and location are similar , the evaluation is not an energy-efficient lighting , requires a combination of these three aspects of energy efficiency lamps come :

Lighting Energy Efficiency = Luminous flux emitted by the lamp / ( Loss source of electrical power + ) = light emitted * LOR / ( + electrical source power loss )

For chestnut : If a 3 * 14W Lamp A, total luminous light source is 3600lm, lighting efficiency is 65% , the whole lamp power is the source power 42W (3 * 14W) plus electrical losses 10W, then it is energy-efficient lighting 45lm / W.

5, LED lamps are energy-efficient ?

After clarifying the evaluation of whether or not the standard of a saving lamps, mutatis mutandis, to find the right thing as long as we can judge the merits of these two fixtures .

Taking a brand 3 * 14W Grille with , for example, when it uses three lamps 14W/1200lm , and with a single tube 14W ballast and one pair of tube 2 * 14W ballast , the system power is 18 +32.5 = 50.5W. Grille efficiency LOR = 75%, then the lighting system efficiency is 3600 * 75% / 50.5W = 53.47lm / W.

At this point, as long as the corresponding type LED lamps to replace energy-efficient lamps 3 * 14W higher than 53.47lm / W, we can say that it is energy-efficient.

Summary: When we designed the "choose Light" link, select the appropriate light source is mainly supporting the right appliances, as well as proper lighting , energy efficiency is one aspect to consider .

When considering the energy efficiency of our design, we can not just use any type of technology and light , but also the actual parameters lighting, electrical and lighting , it is best able to sample and measure the physical examination .

From this we can see that now popular to say how much money one watt LED is actually very not justified, because the owners purchase lamps to buy is "light" instead of " power " ; using yuan / watt to measure LED, likely to buy low light efficiency is not energy-efficient LED products in the lighting level to consider the correct measure of economic indicators should be RMB / thousand lumens, behind us again in detail.

Scriptures of how lighting design photo

Once you have analyzed the space and the desired effect , you can use three basic lighting approach to lighting design.

Ambient lighting - basic lighting, it means :

● people can easily and safely move

● show that features space

● make the space look bigger

● surface brightness make the space more comfortable by balancing the space

The lower surface of the object and the space under the illuminated illuminate basic lighting can create a feeling of warmth and intimacy , and illuminate the ceiling and walls of the indirect lighting , it makes the space look more rational , quiet, and spacious.

Accent lighting - illuminate special areas

Accent lighting additional light on the particular surface. Accent lighting can attract the eye, enhanced dramatic effect , causing people's interest. Like saying : "Hey, look here ! "

Task lighting - illuminate the face

Task lighting is to illuminate the area of our work : such as reading , writing, preparing food , the laundry , games or manual operation. Writing and reading in general need to have plenty of good diffused light is irradiated from the shoulder or side ; while for kitchen and hand , the focus is usually a bunch of light from above irradiation can play a very good effect.

What are the areas that need lighting

In determining " how photos" when a key element is to control the position of the lamp , which is especially important to avoid reflective glare and light curtains . Meanwhile , it is also emphasized that the surface texture of the decisive factors weaken performance.

When the lamp is very close to the wall , lighting is likely to expose flaws in the wall or illuminated object . And in this case , grazing is easier than wall wash highlights flaws。
