The LED street lights is applied to the street lamp through the special light shape design of the LED street lights, which can offset the luminous angle of the lamp and improve the lighting utilization rate of the roadside; according to the rectangular aspect ratio, the aspect ratio can be 2: 1 light spot, so that there will be no shadows between adjacent light spots, and a bright light band with uniform illumination can be formed on the road, which is more in line with the current lighting design of traffic roads, without the need to increase the height of the light pole. It satisfies a wide enough illumination range, and also improves the lighting efficiency of the lamps and reduces the lighting power density of the road, so as to truly achieve energy saving and green environmental protection. The high-power Outdoor LED street light is used for road lighting. Compared with the traditional high-pressure sodium lamp, it has nothing Comparable advantages: 1. The light-emitting mechanism is different. Because outdoor LED street light are a kind of semiconductor device, their effective life can reach 50,000 hours (that is, the light attenuation is less than 30% after 50,000 hours), which is much higher than sodium lamps and metal halide lamps (their life is about In 12000-15000 hours). 2. Since the LED street light is a semiconductor material, there is no filament or other additional materials, so it has good shock resistance. 3. The color rendering index of LED street light source lighting can reach above 80, which is relatively close to natural light. In this case, human eyes can distinguish things more easily, which is beneficial to driving safety; while the color rendering index of high-pressure sodium lamps is only 20-30. 4. Traditional gas discharge lamps such as high-pressure sodium lamps have a preheating process when starting, which wastes energy and is not conducive to intelligent control; outdoor LED street light are essentially different in light sources, so there is no "start-up time" problem , It can work normally immediately after power-on, and can realize intelligent energy-saving control very conveniently. 5. Since traditional street light sources use mercury vapor mechanism to emit light, the disposal of waste light sources is also an urgent problem to be solved worldwide. At the same time, the light-emitting mechanism of traditional light sources determines that it emits ultraviolet rays that are harmful to the human body. The LED street light source is solid-state lighting, without harmful substances such as mercury and other elements, and it does not emit ultraviolet rays. Therefore, it is an environmentally friendly light source. 6. In the optical system, the traditional street light source emits omnidirectional light, half of the light needs to be reflected by the reflector, and the reflector needs to absorb part of the light, so the light loss is relatively large. Since LED street lights emit light in one direction, the utilization rate of light is higher than that of traditional street lights. 7. The light distribution curve of the traditional street lamp is determined by the reflector, so it has certain limitations, while the outdoor LED street light source is a distributed light source. The design of each electric light source can make the light source of the lamp an ideal batwing shape. , By reasonably controlling the light distribution, the pavement spot is rectangular, and within the effective irradiation range, a higher uniformity of illuminance can be obtained. 8. More complete automatic control (optional): Different brightness can be set according to the needs of different time periods, which further improves the effect of energy saving. For example, the brightness is 200W at 7 o'clock in the evening, and when there are few people at midnight, the brightness is automatically adjusted to 100W, of which 60W can be saved.At present, lighting consumption accounts for about 20% of the entire power consumption, and greatly reducing lighting power consumption is an important way to save energy. Outdoor LED street light are attracting the world's attention with their solid advantages.
June 24th is the Fiesta de San Juan in Spain, one of the most lively festivals in Spain. Although this holiday has been associated with Christianity for centuries, its origin is pagan.To this day, Spaniards still celebrate this holiday every year, not only to celebrate San Juan’s birthday, but also to welcome the summer solstice (Solsticio de Verano) on June 21. In 2015, UNESCO declared it as an intangible cultural heritage.Fire is an important part of this festival. It can scare away evil souls and forget all the bad things that happened during the year. Therefore, on the eve of San Juan (Víspera de San Juan or Noche de San Juan), people set up bonfires at the highest point in the city, lit torches (las fallas), set off fireworks and firecrackers in street squares, and also discarded items. Burn a torch to celebrate this holiday. Dancing and fireworks, food and bonfires, people began to carve until the next day. Spain has such a city of San Juan (SAN JUAN), a city under the Autonomous Community of Catalonia, near Barcelona. This is a very unique city with a history of more than 2,000 years. This San Juan festival is said to come from this city, and then swept all over Spain. Because of its long history and many ancient castles, this city has become a mecca for tourists from all over the world.Due to the long time, many street lights have been in disrepair for a long time, and government departments hope to update the entire city's lighting system. The requirements for this bidding are very demanding. First, all lamps are required to have ENEC certification and pass a series of tests. These are not problems for the team of CHZ Lighting Spain. First of all, all of our street lamp products have ENEC certification, and the product quality fully meets the requirements of customers; then, our team conducted a field survey of the entire renovation area, such as road width, light pole height, etc., refer to customer contrast And the requirements of uniformity, lighting calculations have been carried out for all roads, and the most suitable products have been selected. Finally, the selected products are street lights ST23, ST25, and garden lights ST26A. There are many brands participating in the bidding. In addition to the traditional European powers, such as PHILIPS and THORN, there are also many Chinese brands. The competition is very fierce. Finally, relying on our reliable brand and professional design, won the trust of government departments and won this project.Entering the supply stage, the technical team and construction team of the Spanish company began to settle in and do every detail work. This time, for different streets, we chose ST23-90W, ST25-38W and other street lights as well as ST26A-37W, ST26A-56W, Garden lights such as ST26A-90W, and choose the most suitable light distribution, to achieve the ultimate work; if a palace is restored, the goal is to rejuvenate the ancient palace. After the intense construction of the Spanish team of CHZ Lighting, within one month, most of the project progress was completed. The whole set of results is shocking. Many citizens are very satisfied with this effect. The praise is beyond my imagination! The project is still in progress and is expected to be completed in mid-March. Judging from the current situation, the completed blocks have won high praise from government departments this year, and a large number of citizens have begun to cheer on the streets. This year's Fiesta de San Juan will be even more exciting. For the renovation of other blocks, the government departments can’t wait to meet with our team and express their admiration for the professionalism and dedication of our team. Our company will continue to uphold the highly responsible spirit and complete the renovation of this street light. At the same time, we will continue to work hard to contribute more high-quality projects to the road lighting industry in the Barcelona region and the entire Catalonia Autonomous Region.
Solar LED garden lights mainly rely on solar panels to generate electricity. The electrical energy is stored in the battery through the solar controller. There is no need for manual control. It can automatically turn on and off according to the light level regardless of spring, summer, autumn and winter. All charging, discharging, opening and closing are complete. Complete intelligent and automated control. Next, let us understand the characteristics of solar LED garden lights.Light:The light does not contain ultraviolet rays and infrared rays, and does not produce radiation (normal light rays contain ultraviolet rays and infrared rays).Super life:The semiconductor chip emits light, no filament, no bubble, not afraid of vibration, not easy to break, and the service life can reach 50,000 hours (the service life of ordinary incandescent lamps is only 1,000 hours, and the service life of ordinary energy-saving lamps is only 8,000 hours).Green:It does not contain harmful elements such as mercury and xenon, which is conducive to recycling and utilization, and does not produce electromagnetic interference (ordinary lamps contain elements such as mercury and lead, and electronic ballasts in energy-saving lamps will cause electromagnetic interference).High light efficiency, low heat generation:90% of the electric energy is converted into visible light (80% of the electric energy of ordinary incandescent lamps is converted into heat energy, and only 20% of the electric energy is converted into light energy).Protect eyesight:DC drive, no stroboscopic (ordinary lights are driven by AC, so stroboscopic will inevitably occur).High coefficient:The required voltage and current are small, the heat is small, and there is no hidden danger, and it can be used in dangerous places such as mines.
As the earth's resources become increasingly scarce, the investment cost of basic energy is increasing, and various safety and pollution hazards can be said to be ubiquitous. As a kind of "inexhaustible and inexhaustible" safe and environmentally friendly new energy source, solar powered has attracted more and more attention. In this way, solar powered garden lights products should emerge with the popularization of solar water heaters. Here we make a practical comparison between the effects of solar garden lights and the use of city electricity lamps.Advantages of solar powered garden lights:The solar garden light is easy to install: When installing, there is no need to lay complicated lines, just make a cement base and fix it with stainless steel screws. ComparedSolar lighting lamps are free of electricity fees: Solar courtyard lamps are a one-time investment, without any maintenance costs, the investment cost can be recovered in three years, and long-term benefits. There is no hidden safety hazard for solar lamps: solar lamps are ultra-low voltage products, which are safe and reliable in operation.Disadvantages of solar powered garden lights:Low efficiency and high cost: Some aspects of the development level of solar energy utilization are theoretically feasible and technically mature. However, some solar energy utilization devices have low efficiency and high cost. In general, the economy cannot compete with conventional energy sources.Dispersibility: Although the total amount of solar radiation reaching the earth's surface is large, the energy flow density is very low. Therefore, when using solar energy, to obtain a certain conversion power, a set of collection and conversion equipment with a considerable area is often required, and the cost is relatively high.Instability: The solar irradiance that reaches a certain ground is both intermittent and extremely unstable. In order to make solar energy a continuous and stable energy source, it will eventually become an alternative energy source that can compete with conventional energy sources. It is necessary to solve the problem of energy storage, that is, to store the solar radiant energy during the sunny day as much as possible for use at night or on cloudy and rainy days. However, energy storage is also one of the weaker links in the utilization of solar energy.
