Accompanying drawing explanation
Fig. 1 is the operation principle block diagram of an embodiment in the utility model.
Fig. 2 is the fundamental diagram of an embodiment in the utility model.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail below by concrete execution mode.
Refer to Fig. 1, shown in figure is a kind of dual-mode FM photo-reactive lamp, includes, is arranged at the green LED lamp set 1 in light source printed board and white led lamps group 2, and described white led lamps group is used in the normal mode, and described green LED lamp set is in order to night vision mode.Green LED lamp set and the staggered high power valve LED light source of white led lamps group two kinds, high power valve LED Reflow Soldering is welded on light source board, sprays SCC3 silicone resin rete protective agent after welding on light source board parts.Be screwed again on back casing after placed insulation board above, be coated with heat-conducting silicone grease between contact-making surface to reduce thermal resistance.LED the heat sent out can be directly transferred on lamp housing by back casing and dispel the heat with extraneous convection current.The staggered spray fine sand white that is simultaneously also added with is carried out to different LED for reaching required optical index there is the YB-3 aerial organic glass lampshade of diffusion, make the illumination degree on face to be illuminated reach the problem that requirement also solves dazzle.Chromaticity coordinates in optical property and spoke brightness are all ensured by LED self, and brightness value is regulated and controled by the electric current in circuit.
Control circuit part is made up of potentiometer with switch 8, filter circuit unit 3, power protecting circuit unit 4, constant current feedback circuit unit 7, DC/DC conversion circuit unit 5 and on-off control circuit unit 6; wherein, the output termination green LED lamp set of the input termination DC/DC conversion circuit unit of DC/DC conversion circuit unit and white led lamps group.In the present embodiment, as shown in Figure 2, control circuit part comprises integrated circuit U1, time-base circuit U2, integrated circuit U3, paster tantalum electric capacity C1-C2, patch capacitor CX1-CX4, patch capacitor C3-C10, Chip-R R1-R14, Chip-R R17-R20, Chip-R RS1-RS2, Chip-R RX1-RX2, stamp-mounting-paper diode D1, TVS pipe D2-D3, paster triode Q1-Q3, paster magnetic bead L01-L02, paster common mode inductance LG1-LG2, LED light-emitting diode LW1-LW2 and LG1-LG2, potentiometer with switch.Dual-mode FM photo-reactive lamp provides rated operational voltage 28.5VDC by aircraft, the LED rated current that the present embodiment adopts is 350mA, the single channel maximum operating currenbt of design white light patterns and night vision mode is respectively 120mA, 110mA, while meeting optical property, produce lower heat with lower power consumption as far as possible.Owing to employing integrated circuit U1 and time-base circuit U2 at drive end, become the main heating source of control circuit, total power consumption based on drive circuit is not more than 8W, its printed board can be made to be fixed on back casing every sky, and very little heat of U1 and U2 itself can be dispelled the heat by the hole seam free convection of back casing.The high power valve LED of dual-mode FM photo-reactive lamp is driven by integrated circuit (IC) chip, provides 28.5VDC power supply, selected the conversion of normal mode and night vision mode by button switch K 1 with electric connector is crosslinked.
