S3. metal heat sink is embedded in through hole;
S4. flip-over type LED chip is welded on PCB counter electrode pin place;
S5. the fluorescent powder silica gel that instillation changes in temperature colour temperature is alternate in box dam;
S6. heat and when making fluorescent powder silica gel reach semi-cured state, use microlens array template that fluorescent powder silica gel carries out impressing plastic packaging further curing molding;
S7. at LED panel back side respective metal heat sink place's welding electric wire;
S8. the LED panel of respective numbers is mounted on fast-assembling bracket, and lead plate is installed;
S9., electric wire and bracket base are installed.
10. the control method of a kind of car headlamp module realizing light switching and brightness regulation according to any one of claim 1 to 8, it is characterized in that: the control logic realizing light switching and brightness regulation is: P1. realizes long-and-short distant light switching: in LED panel, the 1st is control dipped headlights to M/2 row, and it is control high beam that M/2+1 walks to M row;
P2. the switching of changes in temperature colour temperature light is realized: LED panel is cool colour temperature light by the line number of the fluorescent powder silica gel plastic packaging of cool colour temperature, the line number of the fluorescent powder silica gel plastic packaging of warm colour temperature is warm colour temperature light;
P3. brightness regulation is realized: in the ordinary course of things, before the LED chip connected with a line in LED panel is, (50%~70%) × N arranges, when needs increase brightness, after continuing to turn on same a line, (30%~50%) × N row chip carries out light filling, when needs weaken brightness, then only connect (30%~50%) × N row before same a line, wherein, (50%~70%) × N and the equal round numbers of (30%~50%) × N.
