the advantages of outdoor lighting application in led city-尊龙凯时平台入口

advantage：

1, the efficiency is high: the luminous efficiency of led is not high, but the spectrum of led almost concentrates on the visible frequency band, the optical efficiency is about 65%, and the monochromatic property is good. without filtering, it can directly send colored visible light, and the light is pure. the incandescent lamp has a visible light efficiency of only 10~20%.

2, less energy consumption: led power is generally 0.03 to 1w. it can meet the needs of all kinds of modeling by cluster. because of its no ultraviolet in its spectrum, it has no heat and no radiation loss. when the color light is needed, its inherent color avoids the time-consuming and energy consuming of the white light through the filter. it does not form light pollution, it is a real green light source.

3, safe and reliable: led monomer working voltage between 1.5 and 5v, working current between 20 and 70ma, human contact is not dangerous. the lamp body epoxy resin encapsulation, resistance to mechanical shock, strong vibration ability and no mercury, sodium and other harmful substances, can be recycled.

4, convenient management: led light source because of the above characteristics, can be centralized control and decentralized control or adjustable control of a variety of ways. by controlling the current dimming, different colors are combined to adjust the color, and the control circuit is added to achieve a variety of dynamic changes. the life span of more than 50 thousand hours has reduced the maintenance work of the city landscape.

5, the social and economic benefits: compared with traditional lighting, led lighting products, especially the gan based white led light source, small volume and light weight, good direction and resistant to all kinds of harsh conditions, advantages in power consumption, life and other aspects of environmental protection are incomparable, enough to cause great impact on the traditional market light source.

the lighting is essential in our daily life, so, how do we make better use of the resources of good lighting? first of all, we should make a reasonable design in the lighting of the building.

outdoor lighting project

1, public buildings and industrial building corridors, staircases, halls and other public areas, should be selected according to the gathered control, the construction and use of natural lighting conditions and adopt zoning, grouping control measures.

2, stadiums, theaters, lounge, waiting hall and other public places should be selected according to the needs of the adoption of converged control, dimming or falling illumination control measures.

3. every room in the hotel should be equipped with an energy saving control switch.

4, living in the building of natural lighting staircase, walkway lighting, in addition to emergency lighting, it is appropriate to use energy saving self extinguishing switch.

5. the number of light sources controlled by each lighting switch should not be too much. the number of lights in each room should not be less than 2 (only 1 light sources are set outside).

6. when rooms or occasions are equipped with two or more columns of lamps, the following methods should be operated:

1) the controlled lamp is parallel to the side window.

2) the production situation is grouped according to the workshop, section or process.

3) audio-visual classroom, conference hall, multi function hall, presentation hall and other occasions, close to or far away from the rostrum.
