Now the LED Street Light spent a lot of cost on top of heat dissipation.And big volume, weight big, ugly appearance, if you can the local heat transfer to the chimney, not only can reduce the cost and weight, also can increase the cooling effect.
If you want to make good use of the chimney to heat dissipation, must solve the problem from the LED chip to the link of the lampshade, heat transfer in the interface must be less, thermal resistance from the small.Considering the COB interest superiority, the future of LED COB form, industrial and mining lamp can use aluminum plate with aluminum board directly as the LED mining lamp shade, it is a way of heat transfer interface at least, and the isolation of electrical source of metal halide lamp, safety and easy to pass, because even if one thousand current breakdown encapsulation adhesive, ping an electric current is less than 36 v.
Growth rate of 30% of Chinese mainland in 2012 the main reason for the previous order in large lots of MOCVD machines, pass the about 150 to 2012 and put into production, but it is worth noting is mainland LED mining lamp products will continue to give priority to with low power.From the point of high brightness LED application proportion don‘t change, 2012 large size proportion with LED backlight will be 34.1% higher than that of other applications, will amount to 16.7% floodlight lighting application, forecast to 2014, the proportion of the two will be 28.7%, 28.7% respectively, to develop more rapidly led high bay light bulb market, companies in 2012 new product to replace 60 w incandescent lamp is given priority to, but it is worth noting that is quite a 60 w brightness of 800 lmled bulb price is still high, $40, and the sweet spot is also required by the district market price difference, Japan area for around $15, $25, Europe and the emerging areas around $7.Proportion of energy-saving light bulbs in 2012 is still high, therefore, relative permeability of LED bulbs will be with the shipment for 5.4% counting, will amount to 1.05 billion.
