now. jschindo。 Com there are all kinds of product appearance led street lamps, the arrangement and number of leds luminous particles, the appearance of rectifier circuit size and internal planning. For example, the power of single pipe range from 1 to 5 watts; Light distribution of each are not identical, including bats shape, rectangular, and shape of butterfly wings. Optical processing methods including independent lens, in order to avoid the secondary optical processing and secondary optical processing; Drive status including dedicated drive integrated circuit chip and without power capacitor; Conditions including multiple chip packages and single chip packaging; Skills line state including pattern, group, high power, high power chip integration, lattice power, etc. Optical planning and heat dissipation is led street light the main technical problems. Despite the high power led street light has developed rapidly, but in the use of a series of problems still exist, such as low level of low lumens, secondary processing, low system efficiency, fast attenuation and short service life, light color temperature error, light color is differ, drive many times failure, etc. At the same time, such as secondary optical planning, heat dissipation and power regulator system planning and other major skills is the key to improve the luminous efficiency and prolong life. Currently, the light-emitting diodes (leds) radiation way of lambert, side emission, bats airfoils, rectangular, butterfly wings and concentrating. Through the secondary optical planning, light emitting diode lighting planning and brightness curve to meet the need of road lighting. Led street light category has the following characteristics: 1. Leds lamps overall environment tends to be stable, but the change of government, corruption and other objective factors, led street light speed obviously lower than expected this year, growth is slowing, lead to people more than less, more rational. 2. This year, led street light in all of the road lighting, uniformity and glare control has made great progress. However, due to the huge market demand and LED street lamp manufacturers base, market competition is intense, the LED street lamp order mostly concentrated in the plan of larger companies. In the future, the LED street lamp manufacturers will not only fight for quality, will fight for the price. To seek new economic growth point and many policies LED street lamp manufacturers. 3. LED street light has changed the structure of the planning, light modular become a new trend in the future. In previous integration and modular programming, once appear problem, lamps and lanterns must replace the lamps and lanterns. After the light source, however, modular, just change the electrical control part. While from the perspective of a single lamp cannot cost savings, but cheaper in the long run. 4. In the application of LED street lamp intelligent control system is gradually increasing. Many street lamps at home and abroad enterprises start is committed to the development and production of intelligent led lights. Intelligent led street light in the original leds can energy saving 10% on the basis of energy saving technology Insufficient 20%, but intelligent led street lamp system stability, double failure rate, may be worse than street lamp control system.
