It's reasonable. You can find the following features.<br /><strong>1. Heat dissipation</strong></p><p>The application of single pipe heat dissipation technology solves the key problem of calorific value control in LED street lights</p><p><strong>2. Long lifetime.</strong></p><p>Lifetime of LED street lights are up to 50,000 hours, which is 5-10times of sodium lamps and 10-20 times of mercury lamps.</p><p><strong>3. Drive power</strong><br />Constant-current pulse driven by purposelly buile power supply,ensuring a wide voltage range</p><p><strong>4. Wide Operation voltage<br /></strong>adaptable for 170V-250V voltage fluctuation amplitude</p><p><strong>5. High Color Index, Nice Coloration<br /></strong>high color rendering index, close to 1. To show the true colors and more brighter</p><p><strong>6. Color Temperature</strong><br />Non-Flash, lower glare frequency, Customized color temperature between 3000-6000K ,.</p><p><strong>7. Green and Environmental Protection</strong></p>no mercury,sodium and other toxic materials, green and environmental friendly,<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/8792686721263703425-3047826148092774066?l=streetlightstech.blogspot.com' alt='' /></div>Leonoreply@blogger.com0tag:blogger.com,1999:blog-8792686721263703425.post-91869586573374119162008-12-21T23:40:00.000-08:002008-12-21T23:54:24.657-08:00Today I read a white paper in Philips website. It's about performance <a href="http://www.ledlightsorient.com/street-lights-c-8.html">benefits of LED Street lights</a>. Comparing to high pressure sodium lamps and Mercury Vapor lamp, the performance benefits of the LED Street lights are as follow:<br /><ol><li><strong>Lower power consumption (67W)</strong> - save energy use by 52% over Mercury Vapor (138W) and 26% over a high pressure sodium lamps (90W) </li><li><strong>Higher efficacy (50 lm/W)</strong> - LEDs far exceed mercury vapor 31 lm/W and contribut to energy savings again </li><li><strong>More lux per watt (0.21)</strong> - more than double that of a mercury vapor streetlights.<br />Besides it do not have undesirable visibility, safety and glare problems. </li><li><strong>More even light distribution (0.40)</strong> than either of the high pressure sodium lamps and Mercury Vapor lamp, as indicated by the ratio between the minimum and average lux produced in the target zone. The LED scenario was the only.</li></ol><p>If you are also interested in LED street lights or <a href="http://www.ledlightsorient.com/">other LED lighting</a>, please leave a comment.</p><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/8792686721263703425-9186958657337411916?l=streetlightstech.blogspot.com' alt='' /></div>Leonoreply@blogger.com0
