LED street lights seek a breakthrough

With the gradual development of LED lighting products, LED street lighting and other public places, and gradually replace traditional lighting products, LED street lighting products have been recognized and accepted by the market. Reliability LED lighting products and so gradually revealed. In the use of higher power and longtime power business application areas, LED lighting products quickly became the new darling of the market.

LED street lighting to optimize the design and improve the use of LED quality. So the study power LED light source of secondary optics optical design, to meet the large cast light flood lighting with light demand particularly urgent. By the second optical design technology, design and multiple cup plus reflective optical lenses and aspherical surface light can improve the light extraction efficiency of the device.

Under the premise of the production process to ensure that the light distribution characteristics of the same kinds of lamps will reach a consensus. Completely through after several trial, constantly sum up experience, enabling LED lights achieve the bat wing light type road lighting standard. Tunnel lights, street lights and general lighting application areas have reached their lighting requirements.

As we all know, LED is a optoelectronic devices, their work only 15% to 25% of the electrical energy into light energy, almost all the rest of the energy is converted into heat, so that the LED temperature. In the high-power LED, the heat is a big problem. For example, a 10W white LED if the photoelectric conversion efficiency of 20%, the 8W energy is converted into heat, if not avoided cooling measures, the power LED exchanger core temperature will rise rapidly when its junction temperature （TJ） rise above the maximum allowable temperature （usually 150 ℃）， high-power LED will overheat and damage. Therefore, high-power LED street lighting design, the most important job is to design thermal design.

LED street lighting development of the final version is to become modular. All in accordance with the docking between the light source replacement, electrical, etc., so that a skilled worker, but also fully capable of independent judgment cause of the damage and conduct on-site repairs.
