In China, the popularity of LED lighting industry is not comprehensive, and the government's investment support is relatively small, higher production costs, resulting in the current downturn in the LED market. General manufacturers are working with the ordinary LED chip, the luminous efficiency is low and the work effect is poor, can not be used in other fields, this kind of chip can only be used to display more, mainly because of the effect of SMD package. The package is reflected in placing and fixing and sealing, general packaging is mainly in order to protect the LED lamp chip can work normally, prevent the chip is exposed to air or the impact of external factors and gradually failure, and the need to have a certain light extraction rate and heat dissipation, so the use of the general quality of the working efficiency of the LED lamp life relatively good. The use of dispensing machine packaging can make the LED working chip firmly on the LED lamp, and can also play a certain role in protection and buffering, and enhance the work effect, which is difficult for dispensing equipment, the demand is not small.
