Hongli Optoelectronics products include LAMP LED (including in-line LED, piranha LED), SMD LED (including CHIP LED, TOP LED, HIGH POWER LED) devices, as well as LED strips, downlights, fluorescent tubes, panel lights, and shots. Lamps, street lamps and various car lights (including running lights, warning lights, brake lights, turn signals, reversing lights, fog lights, etc.) are mainly concentrated in key areas such as white LEDs and high-power LEDs.
The proportion of Hongli Optoelectronics SMD LEDs continues to increase. In 2010, sales volume increased by 9.6% in 2009 and LAMP LED decreased by 9.61%. In 2008, small-scale production of automotive signal/lighting products began. Although the growth rate was more than four times, the scale was still small and the capacity utilization rate was relatively low.
The company's products are high brightness (10mcd < device normal light intensity ≤ 100mcd) LED. If the high-brightness LED is further subdivided according to the magnitude of the driving current, it can be divided into standard type, high current (High Current) and high power (High Power), among which the packaging technology of high-power LED is the most difficult. Details are as follows: 
First, the advantage
1. Continuous optimization of product structure 
1) The proportion of white light and high power LEDs has increased steadily
In 2010, the sales revenue of white LED devices increased by 16.48% year-on-year, compared with 4.46% in 2009. In 2009 and 2010, the sales revenue of high-power LED devices accounted for 6.26% and 6.31% respectively. The profit margin of Hongli Optoelectronics is basically the same as that of listed companies in the same industry, but the growth rate is relatively fast. This is mainly related to the faster increase of the gross profit margin of white LED products and the increasing proportion of sales. In terms of application range, white LED is the most widely used LED product, and its wide application field and market demand make it have higher bargaining power.
2) The proportion of medium and high-end products has increased steadily
