Specific embodiment

It should be appreciated that specific embodiment described herein is not intended to limit the present invention only to explain the present invention.

Referring to figs. 1 to Fig. 5, an embodiment of the light-operated Split LED lamp of the band of the present invention is proposed：

This with light-operated Split LED lamp include ceiling disk 10, the LED light source plate 20 on the ceiling disk 10, LED driver 40 and lampshade 30.Ceiling disk 10 is made up of the high aluminum alloy materials of thermal conductivity factor, and thermal conductivity is good, for for LED light Source heat-dissipating.LED light source plate 20 is provided with three, and LED light source plate 20 is made up of LED-baseplate and some LED chips, and LED-baseplate is fan Ring frame is arranged, and some LED chips are evenly distributed in LED-baseplate, forms the LED light source plate 20 of fan annular.LED driver 40 Installed in the center of ceiling disk 10, the LED light source plate 20 for fanning annular is uniformly distributed around LED driver 40.Fan annular , around distribution, light distribution is more uniform, and light-out effect is more preferable for LED light source plate 20.

The hollow slots 12 of four curved settings in same circle, 12 liang of two-phases of hollow slots are provided with ceiling disk 10 To being uniformly distributed.The center of circle corresponding to hollow slots 12 is the central point of ceiling disk 10.It is provided with and engraves in the bottom of LED driver 40 The one-to-one cantilever hooks 41 in the position of dead slot 12.The width in the leading portion portion of hollow slots 12 is slightly larger than the thickness of cantilever hooks 41 so that outstanding Arm hook 41 is easily inserted the leading portion portion of hollow slots 12, and the width in the back segment portion of hollow slots 12 is less than its leading portion portion, with clamping cantilever Hook 41.Hollow slots 12 form rotary buckle structure with cantilever hooks 41, and rotary buckle is passed through between ceiling disk 10 and LED driver 40 Structure is connected.

During assembling, the cantilever hooks 41 of the lower end of LED driver 40 are inserted before the hollow slots 12 on corresponding ceiling disk 10 Section portion, is then made in the back segment portion that cantilever hooks 41 turn to corresponding hollow slots 12, mutual clamping by rotation, realizes that LED drives Dynamic device 40 is connected with ceiling disk 10.Assembly operation between ceiling disk 10 and LED driver 40 is convenient, fast, without the need for Using aid, packaging efficiency can be improved.And, when need to remove LED driver 40, only need to be to the contrary of above-mentioned direction of rotation Direction rotating LED driver 40, just can be such that cantilever hooks 41 screw out from hollow slots 12, so as to easily remove LED driver 40, side Just the replacing of LED driver 40 and maintenance.

The built-in driving power supply circuit of LED driver 40 and optically controlled delay circuit.Driving power supply circuit is primary side feedback formula LED Constant-current drive circuit, including the power transformer T7 and former limit of the output end connection of current rectifying and wave filtering circuit and current rectifying and wave filtering circuit Feedback LED constant current driving chip JP1, the output end of primary side feedback LED constant current driving chip JP1 and the input of power transformer T7 End connection, the output end of power transformer T7 is the power output end of driving power supply circuit.

Primary side feedback LED constant current driving chip JP1 is BP9022A chips, and chip internal is integrated with 600V power switch, Only needing to few peripheral assembly can just reach excellent constant-current characteristics, and employ primary side feedback technology, without the need for optocoupler And TL431 feedbacks, to power without assists winding and detect, system cost is extremely low.1 pin of BP9022A chip JP1 is adopted for electric current Sample end CS, meets sampling resistor R3 to ground wire；2 pin of BP9022A chip JP1 are chip power supply end VDD, with current rectifying and wave filtering circuit Output end connects；3 pin of BP9022A chip JP1 be earth terminal GND, ground wire；4 pin of BP9022A chip JP1 are LED open circuits Protection voltage arranges end ROVP, and connecting resistance R2 is to ground wire；5 pin and 6 pin of BP9022A chip JP1 are empty pin NC, BP9022A cores 7 pin and 8 pin of piece JP1 are internal high pressure power tube drain terminal DRAIN, i.e. output end, connect the input of power transformer T7.

The power output end of driving power supply circuit is connected with the power input of optically controlled delay circuit.Optically controlled delay circuit bag Include photo resistance R10, monostable flipflop and switching device, trigger input end and the photo resistance R10 of single-shot trigger circuit Connection, the output end of single-shot trigger circuit is connected with the input of switching device, the signal output part connection LED of switching device Light source board 20.

The resistance of photo resistance R10 follows the change of the luminous intensity of external environment and changes：On daytime, when there is illumination light is mapped to During quick resistance R10, its resistance very little (tens K or so), the now trigger input end input high level of monostable flipflop, not by Triggering, its output end output low level, IGCT Q1 is not turned on, and LED light source plate is in turn-off；Darkness, works as photo resistance When R10 does not have illumination, its resistance increases, now the trigger input end input low level of monostable flipflop, monostable flipflop It is triggered upset by 2 pin, its output end output high level, IGCT Q1 is triggered conducting, LED light source plate is lighted；Realize LED Light fixture automatic distinguishing on daytime, darkness is lighted automatically, energy saving, convenient use.

The rounded setting of the lower port of upper port and lampshade 30 of ceiling disk 10, on lampshade 30 and ceiling disk 10 use is provided with In the rotary buckle structure being connected with each other, rotary buckle structure is by the arc being horizontally installed on the lower end outer wall face of lampshade 30 Draw-in groove 31 and the fixture block 11 being arranged on the internal face of ceiling disk 10 are constituted, and draw-in groove 31 and fixture block 11 are equipped with least two, card Groove 31 is corresponded with fixture block 11, and the one end of draw-in groove 31 is provided with the downward opening entrance being adapted to fixture block 11, the downside of draw-in groove 31 While being inclined to set, it is inclined upwardly to end from arrival end.Fixture block 11 is inserted into one end of draw-in groove 31 from the entrance of draw-in groove 31, so Afterwards rotary lampshade 30 or ceiling disk 10, make lampshade 30 rotate against with ceiling disk 10, and so as to fixture block 11 is rotated draw-in groove 31 is snapped in The other end, make lampshade 30 be connected with ceiling disk 10.

The lower side of draw-in groove 31 is to be inclined upwardly setting from arrival end to end, so as to, the end of draw-in groove 31 width compared with The width of arrival end is little, and when fixture block 11 is rotated to end from arrival end, because width is less and less, fixture block 11 can getting over by card Come tighter, make lampshade 30 and the stable connection of ceiling disk 10.Pass through rotary buckle structure revotating card between lampshade 30 and ceiling disk 10 Connect, attended operation is easy, stable connection can improve packaging efficiency.

The preferred embodiments of the present invention are these are only, the scope of the claims of the present invention is not thereby limited, it is every using this The equivalent structure transformation that bright specification and accompanying drawing content are made, or other related technical fields are directly or indirectly used in, It is included within the scope of the present invention in the same manner.
