Countries around the world have clarified the policy of eliminating or restricting the use of incandescent lamps. Incandescent lamps will gradually withdraw from the historical stage; and the energy-saving lamps that are vigorously promoted are also frequently criticized for environmental protection problems. LED lighting fixtures will become the main lighting fixtures of the future, which has basically gained consensus in the industry. But at present, there are still some problems in the promotion of LED. How can LEDs be accepted by users and truly become mainstream lamps? The author believes that in order to solve the problems currently faced, it is necessary to find an application method that can give full play to its advantages. This is a common test faced by the LED industry.
Innovative design has a way out. The single power of the LED light-emitting diode is not large. If the power is required, several LEDs are needed to reach the design power, so it faces heat dissipation. If this problem cannot be solved effectively, it will affect the life of the product. Current LED luminaires require a heat sink, resulting in increased volume and increased cost.
At present, LED lamps are mostly designed with reference to the basic elements of incandescent lamps and fluorescent lamps, that is, in addition to the luminous tubes, they are based on the original lighting elements, which makes the advantages of LED lighting not fully utilized, and at the same time leads to high cost. The price of LED lamps is several times higher than that of energy-saving lamps and high-pressure sodium lamps. LEDs in the market also affect their competitiveness because of higher prices. Therefore, the pattern structure of the LED lamp inherits the basic pattern of incandescent lamp and fluorescent lamp, which is relatively smooth for the application, but it loses the characteristics of the LED itself, and it is inevitable that it is not competitive because of its shortcomings. Therefore, only innovative design can have a way out to create the future of LED.
DC power supply for LED lamps China LED lighting companies should make a difference in LED applications. The author believes that if you want to create the most able to show the advantages of LED, the premise is to provide DC power, direct supply of LED lamps, reduce the drive circuit, use less electronic components, use space to dissipate heat, lamps can be used less or no radiator. If a road DC system supplies power to it, electronic circuits and components are reduced, saving both cost and life. At present, converting AC power to DC power accounts for about 20% of the cost of the product. As far as the working voltage is concerned, as long as it does not affect the quality of the power supply, no pressure drop can be generated, that is, the design can meet the requirements of the lamp and the power supply.
The lighting fixtures are mainly used indoors and outdoors, and the street lights are mainly used outdoors. These are closely related to the construction of the project, and construction is the largest market for lighting fixtures. The author suggests whether it is possible to consider providing DC low-voltage power supply for lighting systems in new buildings; and also to develop DC low-voltage power supply systems in road lighting. This will reduce the cost, and the future of LED lighting will be broader. I believe that it will become a mainstream lighting fixture.
The application of direct current systems to LED lamps directly reduces the cost of lighting products and is an innovative idea. However, there are also many technical and management issues, which are worth further exploration and reflection.
