The specific embodiment
The utility model proposes a kind of LED spotlight with deployed configuration; Comprise substrate and basic onboard led lamp; Be provided with reflex reflector around the LED lamp, and reflex reflector comprises reflector, reflector comprises moving fan plate and decides reflector; Moving fan plate is the fan annular, decide reflector be located at fan ring place circle, with the breach of fan ring complementation in; Deciding reflector is fixed on the said substrate; Moving fan plate has a relief area with the centre of deciding reflector, establishes the LED lamp in this relief area; On substrate, be provided with the groove of strip, be provided with slide mass, fixed body and automatically controlled spring spool in the groove; Fixation postures has a through hole on fixed body between slide mass and automatically controlled spring spool, the serving of automatically controlled spring spool passes this through hole and is connected on the slide mass, on the serving between slide mass and the fixed body, is with spring; Moving fan plate comprises two fan-shaped fractures; Comprise outer dead centre and inner vertex on the fracture; The top of slide mass and fixed body and the inner vertex of fracture are rotationally connected through rotational structure; When automatically controlled spring spool reclaims serving, the fan plate is upwards turned up by substrate, moving fan plate is upwards turned up it and is surrounded a funnel shaped.
Below through embodiment the technical scheme of the utility model is elaborated, but the protection domain of the utility model is not limited to the following scope of putting down in writing.
The embodiment of the light fixture that the utility model relates to is extremely shown in Figure 4 referring to Fig. 1.This LED lamp device comprises substrate 6 and basic onboard led lamp 5, around LED lamp 5, is provided with reflex reflector.
Reflex reflector comprises reflector, and reflector comprises moving fan plate 1 and decides reflector 4.Moving fan plate 1 is the fan annular, decide reflector 4 be located at fan ring place circle, with the complementary breach of fan ring in, it can take whole barbed portion, also can only account for a little zone of barbed portion, but for back kind situation, the reflecting effect meeting is more inferior.Deciding reflector 4 is fixed on the substrate 6.Moving fan plate 1 has a relief area 3 with the centre of deciding reflector 4, establishes LED lamp 5 in this relief area 3.LED lamp 5 can be that packaged type and packaged fluorescent tube are welded on the device on the aluminium base on paster LED, the plate.
On substrate 6, be provided with the groove 11 of strip, be provided with slide mass 2, fixed body 10 and automatically controlled spring spool 9 in the groove 11.Slide mass is preferably carriage device.Fixed body 10 has a through hole 14 on fixed body 10 between slide mass 2 and automatically controlled spring spool 9, the serving 8 of automatically controlled spring spool 9 passes this through hole 14 and is connected on the slide mass 2, on the serving between slide mass 2 and the fixed body 10, is with spring 7.Automatically controlled spring spool 9 is made up of motor driver and spring spool, and motor driver is connected with the spool of spring spool, and motor driver drives this spool and rotates, and makes its scrolling serving.
Moving fan plate 1 comprises two fan-shaped fractures; I.e. first fracture 12 and second fracture 13; Comprise outer dead centre and inner vertex on the fracture, the top of slide mass and fixed body and the inner vertex of fracture are rotationally connected through rotational structure, when automatically controlled spring spool 9 reclaims serving 8; The fan plate is upwards turned up by substrate, and moving fan plate is upwards turned up it and is surrounded a funnel shaped.
In one embodiment, reflector can be plastics or glued board material, its surface plating reflectorized material.
Deciding reflector can be for fanning annular shape, and is and the complementary fan ring of moving fan plate place circle.Decide reflector and be fixed on the aluminium base, so whether its shape is that the fan ring is unimportant, it can be designed to other shape.Can know by Fig. 1, decide the zone of reflector 4 between first fracture 12 and second fracture 13, promptly fan ring place circle, with the complementary breach of fan ring in.
In conjunction with Fig. 2 and shown in Figure 4, during use, start automatically controlled spring spool earlier and reclaim serving.The serving slide mass 2 of pulling back, and compression spring, this moment, moving fan plate can surround automatically, and until the structure that surrounds a reflection shield tube, this moment, light fixture presented spot condition, can make the LED lamp send optically focused.If want to use zero diopter, then break off the power supply of automatically controlled spring spool, then slide mass is under the restoring force effect of spring, to motion at a distance; And then drive moving fan plate development, it is tiled on the substrate, referring to shown in Figure 3; Because decide the cooperation of reflector, they can provide complete reflecting effect, the light that send this moment does not have optically focused property; Relatively disperse,, just can send not dazzling light if on the LED lamp, cooperate a honeycomb secondary lens.
