LED lighting street lights have the following characteristics: Energy saving, The new type of green environmental protection, Long life. The lamp structure is reasonable. The light color is simple and the light color is many. High security.

Designers and owners hope that the selected LED lamps not only have exquisite appearance, but also have natural, comfortable and beautiful lighting effects. At the same time, they should consider saving costs as much as possible. In order to fully meet the needs of customers, enterprises with a sense of responsibility and innovation, in product design, pay attention to the research and development and design of the whole lamp, are committed to the perfect combination of lamps and light sources, and regard the creation of high-quality light environment art as the mission of the enterprise.

Since the emergence of blue light, white light and high-brightness LEDs in the 1990s, the luminous efficiency of LEDs has been continuously improved, and commercial LED tubes have now reached the luminous efficiency of 50 lm/W~100 lm/W, and its luminous efficiency is still with continuous improvement, it is estimated that it will eventually reach about 200 lm/W, which is not only much higher than 10 lm/W~30 lm/W incandescent lamps (including tungsten halogen lamps), but also much higher than all current light sources. However, the power of a single LED is very small, only 1 W ~ 5 W, and the luminous efficiency is only a few hundred lumens, and the stage lamps often have a power of kilowatts and a luminous flux of tens of thousands of lumens. Therefore, many people have never thought of using LEDs before stage lighting.

At the beginning of this century, blue LEDs were popularized, white LED technology gradually matured, the luminous efficiency of LEDs was doubled compared to incandescent lamps, and the lifespan of high-power (watt-level) LEDs could reach tens of thousands of hours. With the advantages of light convenience, new LED stage lamps that combine multiple LEDs to increase the total luminous flux begin to appear. At first, due to technical reasons and expensive prices, this kind of lamps was rarely used. In recent years, due to the improvement of the luminous efficiency of LED lamps and the popularization of accessories such as condenser cups, tube cores and shells, many manufacturers have begun to assemble and produce them. LED lamps have attracted people to try because of their bright color, energy saving and environmental protection.

LED fluorescent lamps are increasingly entering people’s lives with their unique advantages. What are the advantages of this light? Let’s take a look today.

In the decoration, lamps are an indispensable thing. It is not so much a decoration project as it is the most basic living needs.

Since recent years, the national economic health development, the national infrastructure construction, the construction of the railway, the railway, and the public road construction. This is an increase in the amount of demand for tunnel lights. Energy saving, energy saving environment, lighting quality of the tunnel, energy saving of the same time, management of the tunnel, special lighting environment of the tunnel.

The working principle of the energy-saving lamp is to heat the lamp filament through the ballast. At about 1160K temperature, the filament starts to emit electrons (because some electron powder is coated on the filament), and the electrons collide with the argon atoms to produce inelastic collisions, and the argon atoms. After the collision, it obtains energy and then hits the mercury atom. The mercury atom undergoes ionization after absorbing the energy, and emits ultraviolet rays of 253.7nm. The ultraviolet rays excite the phosphor to emit light. Because the temperature of the filament when the fluorescent lamp is working about 1160K, which is 2200K higher than that of the incandescent lamp. -2700K is much lower, so its life is also greatly improved, reaching more than 5000 hours. Because it does not have the current heating effect like incandescent lamps, the energy conversion efficiency of phosphors is also very high, reaching more than 60 lumens per watt.

Whether the LED lamp is stable or not, the quality is most closely related to the heat dissipation capacity of the lamp body itself. At present, the heat dissipation of high-brightness LED lamps on the market usually adopts natural heat dissipation, and the effect is not ideal. If the heat dissipation is not ideal, the life of the lamp itself will also be affected.

Compared with other lamps, LED lamps have outstanding advantages: energy saving, long life, green environmental protection. However, the quality of LED lamps varies greatly, and consumers do not know how to choose? In view of the current vicious competition in the market price of flat panel lamps, the listing of a large number of substandard products (inferior goods and bad goods) has violated LED energy saving, long life, environmental protection and other real values, contrary to the significance of applying LED technology to the field of integrated ceiling, and seriously affect the healthy development of integrated ceiling LED panel lights. How to distinguish the advantages and disadvantages of LED lamps mainly depends on the following aspects
