Led Street Light Save Power
With the ongoing energy consumption, the enhancing lack of resources
, the green house effect on people become increasingly considerable hazards, air contaminants on the Earth's environment more and more serious, preserving energy and reducing consumption requirements of the international community is enhancing, today's energy-efficiency become the most important task. As early as 1996, China officially launched on the green lighting style project, mild design project to save resources, prevent contaminants, and our years to come. Over the years, through the joint efforts of all various departments, as a fourth-generation semiconductor mild (LED) lighting style products has been rapid development in the economical achievements. Chinese road lighting style lighting design accounts for a whole 30% of electricity consumption, and it is closely related to production and way of lifestyle. LED road lighting style as an important outside applications, its advantages:
1. high-power long-life LED road lamp
Members of the focus important, as many domestic and foreign experts and the company's products described in advertising pictures 5-10 million hours, and positive attitude, a aspect in fact, high-power LED road mild way of lifestyle depends on the following points: 1) LED mild chip fantastic, value-ray attenuation. 2) LED overall look engineering, Stability and reliability. 3) LED mild is a cold mild, but the LED semiconductor itself will have heated. LED heated dissipation, LED to create sure good operating conditions. (4) energy, current-driven assure the fantastic.
2. energy efficient
Lighting is a systems engineering project, whether it is prescribed as mild design or lighting style the atmosphere are converted into energy through mild, through the projection mild to be a partially head-to-head to achieve a certain degree of lighting design, reliability, shade, and more than being head-to-head Local features of a complete lighting style projects, not simply to compare the use of energy, but through a, comprehensive analysis for assessment.
3. the difference between traditional lighting style and LED lighting
Conventional road lighting style is composed by the mild invest, mild opening and energy place. Because there is enough place and the invest activated carbon and foam plastic rubber heated closing installation to create sure that the considerable conditions of the resource. The mild opening protection grade IP65, protection rating energy place IP45. Provided that traditional lighting style conditions to create sure this protection, you can create any shape, Since the LED road mild and the semiconductor launched the market, long-life mild, with easy elegance of a cost-effective distribution of mild, warm wide range variation, fantastic color-rendering index of the edge, low-voltage, existing energy of the mild with a impressive energy-saving trends. Used for LED road lighting have natural benefits, its advantage lies in: 1) LED as a aspect mild, if the design is cost-effective, to a large extent directly address the traditional curved light-emitting mild has to rely on to fix the second take-ray and visible loss issues; 2.) Light irradiation reliability place controlled, in theory, can be done entirely in the target place evenly, which mild to avoid the traditional "bright light" trend of mild waste; 3) Shade warm wide range recommended, so the application of different occasions, but also improve performance, website an important way; 4) Technologies are still considerable place for improvement.
4. LED streetlights with the rationality of the visible light
LED lighting with different traditions, it has a aspect mild, fantastic lighting design, narrow-beam outcome and so on. LED road lighting so the first thing to consider the limited use of the full flux of radiation to the efficient wide range, road lighting style the road asking for is the effect of the open place beyond the external coating place rather than the efficient wide range of road lighting style. Therefore, efficient control of the distribution of mild, so that LED mild into a lengthy strip along the external coating place with the direction of mild spread, glare at the same time take into account the overall look of a new type of LED lighting design type of the enhancing demands made on staff.
5. the technical performance assessment for existing LED streetlight
6. calculating the energy-saving targets (based on 12 hours per day): Energy savings per year = 365 * 12 * (0.5-0.16) = 1489.2 Electricity savings per year = 1489.2 * 0.8 = 1191.36 yuan After transformation of LED lamps, each lamp to save electricity 1191.36 yuan per year. If the entire road use LED street lamps, so the country will save a lot of power, by economic, a lot of money saved.
