The specific embodiment
Extremely shown in Figure 8 as Fig. 1, a specific embodiment of convertible lamp of the present invention, this convertible lamp is portable flashlight; Certainly, convertible lamp also can be the light fixture of other form, for example searchlight, head lamp, mine lamp or the like.The light fixture of present embodiment has optically focused, floodlight goes out light effect for two kinds.
The convertible lamp of present embodiment comprises lamp main body 300, in the transparent components 100 and the adjusting device between lamp main body 300 and transparent components 100 of lamp main body 300 front ends.This lamp main body 300 comprises shell, battery, circuit board etc. is installed in the enclosure, for light source 211 provides power supply and control signal.The front end of lamp main body 300 also is equipped with reflector, is used for the light of reflection source 211, forms the light effect that of optically focused.And transparent components 100 can be directly installed on the front end of lamp main body 300, as the light path that goes out of light source 211; Certainly, transparent components 100 can also be directly installed on the adjusting ring 220 of adjusting device, rotates together in company with adjusting ring 220.
This adjusting device comprises annular adjusting ring 220 and radially is horizontally set with adjusting rod 210 on the inwall of adjusting ring 220.Inwall at adjusting ring 220 is provided with a pair of relative gathering sill, and this gathering sill comprises first gathering sill 221 and second gathering sill 222 that guide direction is complementary.When rotating adjusting ring 220,, make adjusting rod 210 produce upset, detailed aftermentioned by the guide effect of gathering sill.Shown in Fig. 4,5, this first gathering sill 221 and second gathering sill 222 are a pair of circular groove, and the concave and convex direction of this a pair of groove supports or opposes, thereby realize the effect of control and regulation bar 210 upsets.
For the ease of rotating adjusting ring 220, be provided with hole line 227 at the outer surface of adjusting ring 220, thereby increase the friction between adjusting ring 220 and user's the hand, be convenient to operate.
This adjusting rod 210 is provided with light source 211, and this light source 211 is electrically connected with lamp main body 300, provides power supply and control signal by lamp main body 300, as switch, brightness etc.As shown in Figure 5, for the ease of the installation of light source 211, be provided with mounting blocks 212 in the centre position of adjusting rod 210, light source 211 is installed on this mounting blocks 212; Certainly light source 211 also can be installed in other positions of adjusting rod 210.This light source 211 can adopt LED or other light sources.And in order better to obtain spotlight effect, when rotation adjusting ring 220 made that the light direction of light source 211 points to reflector, light source 211 just in time fell into the focal position of reflector, thereby plays good spotlight effect.
The two ends of this adjusting rod 210 are respectively equipped with the first opposite turning arm 213 of bearing of trend and second turning arm 214, and extend outward first column spinner 215 and second column spinner 216 at the end of first turning arm 213 and second turning arm 214.This first column spinner 215 and second column spinner 216 are inserted into first gathering sill 221 two ends relative with second gathering sill 222 respectively.In the present embodiment, first turning arm 213 and second turning arm 214 and adjusting rod 210 perpendicular settings; First column spinner 215 and second column spinner 216 parallel setting with adjusting rod 210.
When adjusting ring 220 relative lamp main bodies 300 rotate by counterclockwise or clockwise direction, first column spinner 215 of the end of adjusting rod 210 and second column spinner 216 slide in first gathering sill 221 and second gathering sill 222 respectively, because the guide direction of first gathering sill 221 and second gathering sill 222 is opposite, make adjusting rod 210 produce upset, and then the light source 211 that drives on the adjusting rod 210 overturns, the light direction of light source 211 becomes forward or points to state dorsad, shown in Fig. 2,3.When light source 211 pointed to the reflector of lamp main bodies 300, light formed focus irradiation through the reflex of reflector, checked when conveniently working at night that illumination is used or according at a distance; When light source 211 dorsad during the reflector of light fixture, light need not the reflection direct irradiation through reflector, forms the floodlight irradiation, forms uniform illumination, and the road of illuminating nearby makes things convenient for walking at night etc.
After adjusting ring 220 rotations, keep forward or indicating status dorsad in order to ensure light source 211, the present invention has also done further technological improvement, end at first gathering sill 221 and second gathering sill 222 is provided with bayonet socket 224, as shown in Figure 6, be used for first column spinner 215 and second column spinner 216 on the adaptive clamping adjusting rod 210, thereby can locate the position of first column spinner 215 and second column spinner 216, avoid unnecessary slip.
Be installed to for the ease of adjusting rod 210 in the gathering sill of adjusting ring 220, one offering vertical fluting 223 on adjusting ring 220 inwalls along first gathering sill 221 that prolongs on these adjusting ring 220 low sides, shown in Fig. 4,5, and the degree of depth of this vertical fluting 223 is slightly less than the degree of depth of first gathering sill 221.Understandable, vertically slotting 223 can be opened on any one of first gathering sill 221 and second gathering sill 222, also can offer simultaneously at both.
Further technological improvement more of the present invention, at the flexible assembly of gathering sill installed inside of adjusting ring 220, this spring assembly comprises pad 225 and several helical springs 226, as shown in Figure 8; This elastic parts depth direction of groove relatively stretches; Like this, when adjusting rod 210 is installed, can utilize the column spinner of adjusting rod 210 ends to suppress the pad 225 of a side gathering sill, make pad 225 inwardly move, again the column spinner of the other end of adjusting rod 210 is snapped onto the gathering sill of opposite side, after unclamping, under the active force of the elastic recovery of spring 226, compress adjusting rod 210, make that the installation of adjusting rod 210 is more quick, stable.
