Description

Lighting device for parking lot {a illuminator apparatus for prakinglot}

The present invention relates to a lighting apparatus, and more particularly to a parking lighting apparatus to improve the light efficiency.

As the economy develops, office buildings and residential buildings are gradually becoming larger and more diversified.

Buildings for offices are gradually becoming larger, and residential buildings are gradually becoming larger, as well as residential complexes where offices and shopping malls coexist.

On the other hand, as income increases, the number of cars also increases, and many vehicles use the underground parking lot of the building. Therefore, underground parking lot is always complicated and its management is becoming increasingly difficult.

In this way, as the building becomes larger and the number of vehicles parked in the basement of the building increases, the parking lot also becomes larger, so that the cost of managing the parking lot is consumed.

One of these costs is the cost of separate parking lot management personnel to prevent accidents that may occur in the parking lot, and the cost of facility maintenance such as accident prevention and lighting for the convenience of the parking lot user.

In large underground parking lots, crime-like accidents can occur, and most underground parking lots are illuminated with considerable illumination and CCTV is installed.

As an illuminating device for illuminating the underground parking lot, a fluorescent lamp having a relatively low power consumption is used, but a large number of fluorescent lamps are used to obtain a considerable illuminance, resulting in high power consumption.

In addition, since the management of the lighting of the underground parking lot currently implemented depends on the collective on / off using a switch, it puts a lot of burden on the user of the building or in the case of the apartment.

Meanwhile, in order to prevent global warming and also to the environment, conventional lighting devices such as incandescent lamps, fluorescent lamps, and mercury lamps are currently being discharged, and will be completely discharged later.

Many alternatives are being considered as alternatives to such lighting devices, one of the leading candidates being LED lighting devices. As semiconductor manufacturing technology and semiconductor material technology are developing day by day, LEDs that can gradually improve light efficiency and emit various colors have been developed and used.

7 and 8 is a view comparing the light distribution curve of the conventional lighting device for a parking lot according to the present invention.

That is, FIG. 7 shows a light distribution curve of the lighting apparatus for a parking lot according to the prior art, and FIG. 8 shows a light distribution curve of the lighting apparatus for a parking lot according to the present invention.

As shown in Figure 7 and 8, the lighting device for a parking lot of the present invention can be seen that the wider light distribution characteristics on both sides compared to the conventional.

Therefore, by implementing a lighting device for a parking lot with a reflector or round reflection surface as in the present invention, it is possible to light the light in a wider range.

On the other hand, the lighting device for a parking lot according to the first and second embodiments of the present invention forms a reflecting surface together with a reflector, and has a built-in 14W LED bar type inside.

As a result, efficiency can be maximized with low power consumption. That is, the present invention is a power consumption of 12 ~ 14W, compared to the power consumption of 14 ~ 18W in the case of other companies can maintain a high efficiency with low power consumption.

In addition, the present invention is configured to move by installing a separate fixing bracket on the back of the heat sink frame in another embodiment.

In general, the method of illuminating the illumination to the desired position in the limited space of the underground parking lot is very difficult, the present invention can adjust the illumination angle using a removable bracket. For example, depending on the situation, the lighting must be installed vertically or horizontally, so there is an efficient space. It is judged efficiently when the raceway bar is mounted on the ceiling by using a fixing bracket. It can be used when it needs to move down and install.

In other words, it is possible to rotate according to the situation and to fix it by using an angle adjustable bracket. For example, if you look at the entrance or exit of the parking lot, it is judged that it is virtually impossible to adjust the illuminance according to the desired angle to the location without being inclined smoothly. If you use a bracket to fix the problem can be solved.

In addition, the lighting device for a parking lot according to the present invention can reduce unnecessary power consumption by adding a smart echo function. Here, the smart echo function is described in the lighting control system (Application No .: 10-2010-0060502, Registration No .: 10-09800268) filed by the applicant on June 25, 2010. By adjusting the illuminance, it can reduce power consumption and produce optimal emotional lighting.

In other words, the smart eco sensor is integrated to maximize energy savings. In general, the sensor is used to maintain dimming to the parking lot illumination standard method. 60% and 5 ~ 10% in areas without users can save up to 70% of energy compared to existing fluorescent lamps.In areas where cars and people are detected, 100% brightness is automatically converted to the initial state. The maximum effect can be obtained at minimum cost, such as maximizing the lighting when there is a person and minimizing when there is no user.

In addition, the lighting device for a parking lot according to the present invention can be used as a warning light flashing operation light using emergency power in an emergency. This is a method of separating LEDs mounted on PCB board into 2 rows to have a certain interval and informing the danger in red by using emergency power in emergency. In general, the circuit is divided into SMPS and used as a parking lot lighting. Emergency power supply (for example, battery) is attached to the emergency evacuation lights. It uses red LEDs to distinguish channels so that it can only be operated in an emergency.

Therefore, as the emergency power is supplied and the "red" alarm is activated, it can be used as a device to evacuate fire or earthquake quickly, and as an additional function, several situations can be installed programmatically to prevent fire, fire, fire and life. Voice signal devices such as', 'earthquake, earth, foot, life' can also be linked.

Therefore, when the surroundings are bright, the illuminance of the light source is automatically reduced, and by detecting the presence of a person in the surrounding environment, the light source in the non-personal space can be automatically turned off to reduce power consumption.

On the other hand, the present invention described above is not limited to the above-described embodiment and the accompanying drawings, it is possible that various substitutions, modifications and changes within the scope without departing from the spirit of the present invention It will be apparent to those of ordinary skill in Esau.
