Solar Street Light System

We are in the position the react to every requirement quickly and extremely flexibly. Short delivery times, highest quality standards in all our products. DETAILED TECHNICAL QUOTATION Light output: Reflow soldered OSRAM LEDs should be used with cool white light output. LEDs which can be hand soldered should not be used so as to minimize human interference and increase the reliability of LEDs 1. 150 lm /LED at 350mA 2. Asymmetric lenses with 85x135 angle for optimal spread on streets. Lenses should be such that the light output falling behind the pole should be minimized and falling in front and laterally should be maximized 3. Power saving mode after 6 hours of operation up to 50% of savings for longer life Electronics: 4. Microcontroller based PWM charging with the following features: a. Constant Current Phase: all charge current available is used to charge battery. b. Constant voltage Phase: Constant battery voltage towards end charge to present excessive gassing c. Float Stage (below gassing voltage to avoid electrolyte loss) 5. Constant Current driver. Driver efficiency > 90% 6. Reverse polarity protection without the use of fuse to ease up installation in spite of human error 7. Battery charge indicator for different levels of the battery should be present on the fixture, indicating at least 4 levels of battery for easier maintenance. Apart from this, low battery and charging indicators should also be present 8. Parallel back up LED pads with each LED should be present so as to replace the LEDs easily in case one of them fails in future. Physical Luminary: 9. Aluminum die cast body with toughened glass 10. Single piece MCPCB covering the entire aluminum body for good thermal management to increase the life of LEDs 11. LED junction temperature should never exceed 75 degree Celsius
