LED lighting fixtures one of the biggest technical problems is the cooling problem, poor heat dissipation led to LED drive power, electrolytic capacitors have become the further development of LED lighting fixtures, LED light source premature aging reasons. Any radiator, in addition to the heat can be quickly transferred from the heat source to the surface of the radiator, the most important thing is to rely on convection and radiation to heat the heat to the air. Thermal conductivity only solves the heat transfer path, and thermal convection is the main function of the radiator, heat dissipation performance is mainly determined by the ability of heat dissipation area, shape, natural convection strength, heat radiation is only auxiliary role. In general, if the heat from the heat source to the radiator surface distance is less than 5mm, then as long as the material thermal conductivity is greater than 5, the heat can be derived, the rest of the heat ...
Fog in a lot of lights are set: lights, high beam, fog lights, double jump lights, taillights ... ... what lights are open vehicles. 1. Do not leave the spotlight Fog driving must show the lights and front and rear fog lights. Show the lights generally in the steering wheel on the left side of the light pole, turn the first gear is the show lights, also known as night lights, the second gear is the low beam, the third file is high beam. Only to open the profile lights to open before and after the fog lights, and fog lights are fog driving special lights, the main role is to open the fog lamp in order to make other vehicles can better observe you, to avoid rear-end and cut rub occurred. Foggy Many drivers open high beam. In fact, this is counterproductive: high light issued by the white light and white mist mixed together, but more clearly. 2. Bad line of sight Foggy sight is not good, reasonable ground horn can play the role of warning pedestrians a...

Through the Internet and Internet connected to the gateway controller, users can control the connection through the iOS application Tradfri smart light bulb. The update also added support for the Philips Hue bridge, which means that after the update, IKE...
The integrating sphere will homogenize the light emitted by the light source so that the light on the inner surface of the sphere is consistent, so that the luminous flux of the light source is obtained by measuring the illuminance value per unit area by the inner surface area. It can be seen that the uniformity of light distribution is an important index to determine the accuracy of measurement results. Relative to the surrounding light uniform incandescent, energy-saving lamps, the LED because of its strong direction, and relatively special. This makes the LED direct light on the surface of the integrated sphere was unevenly distributed, directly lead to different direct reflection of the LED relative to the detector reflection characteristics are different. Because the position of the detector port and the setting of the baffle are fixed, the different reflection distributions are directly expressed as signal fluctuations. According to the verification...

Chicago intends to replace 250,000 intelligent LED lights in the largest wisdom street program in the United States. Ameresco, a renewable energy company, will work with the World Bank program provider, Silver Spring Networks, in a four-year foundation building modernization program that will convert about 85 percent of Chicago's existing street lights into smart LED lights. According to Smart Cities World, the multi-stage infrastructure modernization program will begin in the summer of 2017. New LED street lamp is expected to save 50 to 75% less than existing street lamps. Silver Spring's IPv6 platform can control the switch lights in real-time depending on the actual requirements, as well as from remote monitoring for active maintenance and road failure. At least half of the installed LED lights will be assembled in the Chicago factory, at least 50 percent of the project will be employed by the Chicago citi...
