(1) Basic information

LED lighting, or light emitting diode lighting, is a semiconductor device that can directly convert electrical energy into light energy. After being electrified, it converts 90% of the electrical energy into light energy. The remaining part of the electrical energy generates a small amount of heat energy when the semiconductor device is working. The electro-optical conversion efficiency is up to 90%

(2) Product introduction

LED lighting fixtures are the general term for LED fixtures. They refer to appliances that can transmit light, distribute and change the light distribution of LED light sources, including all parts needed to fix and protect LED light sources in addition to LED light sources, as well as necessary for connection to power supply. Line accessories. With the further maturity of LED technology, LEDs will achieve more and better development in the field of bedroom lighting design and development. The design of living lamps in the 21st century will be based on LED lamp design, and at the same time fully reflect the development trend of energy-saving, healthy, artistic and humanized lighting, becoming the dominant factor in living lighting culture. In the new century, LED lighting will surely illuminate everyone's room, change everyone's life, and become a great change in lamp development and design.

Compared with ordinary lamps, LED energy-saving lamps have the following characteristics:

1) Efficient energy conservation: Compared with the same brightness, the energy consumption of LED lamps is only 1/10 of that of incandescent lamps and 1/4 of that of energy-saving lamps;

2) Ultra-long life: Semiconductor chips emit light, have no filaments, no glass bubbles, are not afraid of vibration, and are not easy to break

Broken, the service life can reach 50,000 hours;

3) Health: Light contains less ultraviolet and infrared rays and produces less radiation;

4) Green and environmentally friendly: It does not contain harmful elements such as mercury and xenon, which is conducive to recycling;

5) Protect vision: DC drive, no strobe;

6) High light efficiency: At present, the actual light efficiency of LED lamps is about 60lm/W, while that of ordinary lamps is only about 15lm/W;

7) High safety factor: Small voltage and current required, and small safety hazards.
(3) Product application areas

a) LED lamp tube

Suitable for homes, supermarkets, and businesses. Currently, the types are relatively complete, and all fluorescent tubes on the market can be replaced. T5, T8, and T10 have lengths of 600mm, 900mm, 1200mm, and 1500 mm. It can also be customized according to customer requirements.

b) LED bulb.

The original intention is to replace incandescent lamps, so the appearance still continues the shape of incandescent lamps.

c) LED downlight

LED downlight is a type of lighting fixture that is embedded in the ceiling and emits light downward. LED downlight is a directional lighting fixture. Only its opposite side can receive light. The beam angle is concentrated, the light is concentrated, and the contrast between light and dark is strong. The illuminated object is more prominent, with higher brightness, and a quiet environment.

d) LED spotlights

LED spotlights are spotlights that use light emitting diodes as light sources. Traditional spotlights mostly use halogen lamps, which have low luminous efficiency, relatively power consumption, rising ambient temperature and short service life. LEDs are far superior to traditional lighting products in terms of lighting principles, energy conservation and environmental protection. And the LED shines. The one-way nature forms perfect support for the light distribution of spotlights. LED spotlights are mainly used for decoration, commercial space lighting and architectural decoration lighting.

(4) Application cases

Case 1: Office lighting LED renovation project of SMIC Integrated Circuit Manufacturing (Shanghai) Co., Ltd.

1) Implementation content and cycle: SMIC in June 2018~During December, the lights in the office area of the building were replaced, with 13985 lights. Before the project renovation, the power of ordinary lamps was 40W (including rectifiers), and the power of LED lamps after the renovation was 10.5W.

The implementation cycle is 7 months

2) Energy conservation and emission reduction effect and investment payback period: Electricity consumption before project transformation =2376331.2kwh, electricity consumption after project transformation = 623786.9kwh, project energy conservation = electricity consumption before project transformation-electricity consumption before project transformation =2376331.2kwh-623786.9kwh=1752544.3kwh, i.e. 490.71 tons of standard coal.

The payback period is 0.9 years.

Case 2: Shanghai China Resources Dadong Shipping Engineering Co., Ltd. factory lighting LED renovation project.

1) Implementation content and cycle: Specific transformation situation: 780 sets of 200W LED energy-saving lamps were used to replace the original 1000W old iodine tungsten lamp, and 300 sets of 150W LED energy-saving lamps were used to replace the original 800W old iodine tungsten lamp. The replacement ratio is listed as 1:1.

The implementation cycle is 12 months

2) Energy conservation and emission reduction effect and investment payback period: Energy conservation of this project = annual electricity consumption of lighting lamps within the project boundary before renovation-annual electricity consumption of lighting lamps within the project boundary after renovation =2962080kWh-583704kWh=2378376kWh, i.e. 685 tons of standard coal.

The payback period is 0.9 years.
