The emergence of LED lighting products has brought revolutionary changes to the lighting industry, which is second only to the invention of incandescent lamps. Today, no matter whether it is price or quality, its large-scale application has no obstacles. As far as indoor lighting is concerned, a series of bulbs, fluorescent lamps, ceiling lamps, downlights, ceiling lamps, panel lamps, track lamps, spotlights, and the like have been formed.
LED lighting products are composed of all electronic components, two important components of the drive power plus LED lamp beads, are electronic components and structural parts. The processing technology of electronic components is now very mature, so LED lighting products can be easily assembled at will, and there is no particularly disparate technological gap between large companies and small companies. Based on the characteristics of LED lighting products, I have three problems in LED lighting products: one is the interface solution problem; the other is the problem that the technical indicators must be marked; the third is that the LED lighting products themselves will also affect the sales form, which will appear Supermarket LED stores.
LED lighting product interface
The LED lamp with built-in power supply has only one external interface to the outside, such as E27, E14, E40, B22, etc. These interfaces are the interfaces of the early incandescent lamps and energy-saving lamps. The input voltage is the grid voltage, which directly replaces the incandescent. Lights and energy-saving use, ordinary customers can replace it without problems. In addition, for example, panel lights and ceiling lamps, ceiling lamps, etc. are integrated with the light source and the light source. The structure of the lamp is integrated with the power source and the lamp, and only the power input line is externally connected, and the drive and the light source lamp are also separated. Such a lamp forms two interfaces, one is the interface between the LED light source and the driving power source, and the other is the interface between the driving power source and the input power grid. Now these interfaces are part of the interface that used the previous lighting fixtures, and some are chosen by the manufacturer. In particular, the LED fluorescent lamps in the market, especially the brackets of ordinary fluorescent lamps used in the T8 tubes, are connected to the mains at the double end, one end is the neutral line, and one end is the live line. One type is single-ended access to the mains, two feet on one end, one is the zero line and the other is the live line, and the other end is vacant. Imagine that if the single-ended LED fluorescent lamp is damaged and the customer just buys a double-ended LED lighting product, it will cause problems.
Nowadays, the two-terminal two-terminal terminal of the double-ended LED fluorescent tube is connected, and the bracket of the single-ended LED fluorescent lamp is short-circuited immediately. A person with a little electrical common sense will understand the seriousness of the short circuit in the mains. Soon, manufacturers who produce single-ended LED fluorescent lamps will pay for their aesthetic habits and public inconsistencies. Because of the particularity of LED lighting products, the interface standards of previous lamps can not meet the needs of existing lamps, and because of safety issues, it is necessary to limit the LED lighting products that use existing lamps. What you need to do urgently is the limitation, and the interface must be restricted in terms of security. In addition to security issues, manufacturers can freely play and slowly explore suitable interfaces and access methods.
LED product technical indicators
Today's LED lighting products should not meet what standards should be done, the important thing is that in addition to the safety standards must be met, LED product indicators have done what. Lighting requirements for different occasions are different. Reading lights and road lighting are different, and office lighting and aisle lighting are different. Take the life of the LED whole lamp as an example. For example, many lighting fixtures such as corridors, mirrors, and toilets are used for a short period of time. It should be said that the failure time of 2000 thousand hours can meet the demand. And many home lighting does not exceed 4 hours a day, and 1500 hours a year. It should be said that 8000 hours of failed lights are enough. Four years to replace LED lighting products will definitely be higher. Some factories, office and commercial lighting need more than 14 hours a day, and 5,000 hours a year, so the life of the lamp will reach more than 20,000 hours, and the minimum is more than 15,000 hours. Another 24-hour lamp, such as an underground parking garage, is 9000 hours a year. The longer the life of the lamp, the better. The 50,000-hour LED lamp should be the ideal value. In addition, there are specific requirements for color temperature, color rendering index, etc. in different occasions, which are not elaborated here.
