The wide application of LED technology in the 2010 Shanghai World Expo has attracted people's attention. At present, the world's energy is tight, and finding and solving energy problems in the future world has become a top priority. Since the advent of high-brightness white LEDs , it has been characterized by high luminous efficiency, good power saving effect, low energy consumption, safety, low heat, no pollution, long life and excellent economy. It is not only used in lighting, but also in military products and other. Widely used in technology products. The service life of LED lighting is about 80-100,000 hours, and in the case of the same brightness, the power consumption of LED lamps is 1/8 of that of incandescent lamps. It can be predicted that LED will be widely concerned and promoted and applied around the world. At present, the Chinese government is vigorously promoting high-efficiency and energy-saving products, and fully implements the system of government priority and compulsory procurement of energy-saving products. Therefore, it is necessary to explore the application technology of LED lighting.
1 Introduction
LED (Light Emitting Diode), a new modern product component for modern voice control, light control and time control, is a leading product in modern development and a new generation of components in the modern future. It is a semiconductor device that can directly convert electricity into light. It relies on the combination of positive and negative charges in the material to illuminate.
The intrinsic characteristics of the LED determine that it is the most ideal light source to replace the traditional light source, and it has a wide range of (green) new generation components.
2. LED performance characteristics:
2.1 Energy-saving safety (components that modern new energy will replace)
The LED uses a low-voltage power supply. The operating voltage of the general LED is 2-3.6V, the operating current is 0.02-0.03A, and the power consumption of the electric power does not exceed 0.1W. It is an electrical appliance that is safer than using a high-voltage power supply. It has been used on indicator appliances in various public places.
2.2 High brightness, low heat
A light source that measures the brightness of traditional bulbs and is more adjustable and controllable. The power consumption is about 30% of the average bulb, even less than the HID or incandescent bulbs. Safety performance increased by 200%.
2.3 Applicability and small size
LED is basically a small chip packaged in epoxy resin, so it is very small, very light, suitable for a variety of environments, it can also be applied to modern military and technology products.
2.4 Long service life
At the right current and voltage, LEDs can last up to 100,000 hours.
2.5 stable performance
Can work normally for 80,000 to 100,000 hours.
2.6 Short response time
The response time of a normal lamp is milliseconds, and the response time of an LED lamp is nanometer.
2.7 Environmental protection
LEDs are made of non-toxic materials. Unlike mercury-containing fluorescent lamps, they can cause pollution and contain no harmful substances such as mercury. The heat radiation is rare, and LEDs can be recycled.
2.8 Rugged and durable, good shock resistance
It has stronger seismic performance than traditional lamps and is more suitable for and meets the installation requirements of various occasions. The LED is completely encapsulated in epoxy, which is stronger than both the bulb and the fluorescent tube. There are no loose parts in the lamp body. These features make the LED a new component that is not easily damaged.
2.9 Beam concentration
2.10 The calorific value is very small
The heat resistance of the luminaire material is very high.
2.11 Strong controllability
Various color changes can be achieved. It is a modern component of various products, and is applied to new products replaced by new components of sound control, light control and time control.
With the advancement of technology, LED technology has been applied to projectors. There are many good domestic LED projector manufacturers in the market. For example, Shenzhen Resources has perfectly combined this technology with DLP technology to make it portable and compact. Because of its low power consumption and heat generation, it is more widely used in life and in personal business. The same goes for LED hotel projectors.
