led package with high 0.9mm, area 3x4.5mm, is the ideal flat light source; as a result of a ceramic material, these led in a very long period of time to maintain the performance of extremely stable, the service life over 50,000 hours. osram opto collaboration with dolby laboratories, not only to provide a high performance dolby led, dolby also meet stringent application requirements. currently, the use of led backlight display is very clear trend; expected to led backlighting will reach one or two years more than half of consumer tv.recently, optical sea technology developed a new led cooling technology - cohs package cooling technology. the lower operating temperature drop, the higher the optical efficiency in the achievement of this condition can achieve the longest life expectancy, it has the greatest competitive. sea technology optical carrier board design capability using their own advantage, is committed to the development of cooling technology, led light will be directly encapsulated in the sea of high thermal conductivity of the copper seat, due to the high thermal conductivity of copper, just as the role of the radiator, and in circuit design, the advantages of using its own technology to overcome the insulating film and the adhesion between the copper material issues, namely the so-called cohs technology (chips on heat sink).restaurant board
because hbled is solid (made of silicon materials, non-friable), the size is very small and does not contain harmful chemical ingredients (no need to deal with special circumstances.) hbled lighting is designed so that consumers switch to hbled, requires hbled must have a high quality. consumers are demanding the power factor at least 90%, efficiency 80% or higher. in dc applications, the maximum input voltage can not exceed 40v. in ac applications, may use 120v or 240v (maximum 270v) input voltage. hbled must be more than 120hz frequency pulse-width modulator driver, in order to reduce the annoying visible flicker. sometimes, this frequency is also needed is variable. in addition to these design constraints, but also by the engineers and the application to decide to use isolation or non-isolated design. if necessary, the final complex may also consider using the dimming circuit. as you can see, there is not a universal solution.for sale boards
complete heating and cooling parts of the heat transfer area, but also play a role in shock absorption insulation seals to meet the social facilities of the small ultra-thin design is of great use of technology and new materials. and thickness of the wide range of applications, especially for the automotive, displays, computers and other electronic equipment, and power industries. fire retardant performance meets ul 94v-0 requirements, and certification of compliance with eu sgs environmental temperature is generally -50 ℃ ~ 220 ℃ welcome to inquire, we will send you detailed information and sample, thank you!vinyl banner
