For other purposes of the present utility model and advantage thereof are described, existing with following preferred embodiment conjunction with figs. description as after, wherein:
Figure 1 shows that the structure dress exploded view of traditional visible laser diode.
Figure 2 shows that a three-dimensional exploded view of the visible light laser designator of the traditional visible laser diode that uses Fig. 1.
Figure 3 shows that the floor map of the visible laser diode that the utility model uses.
Figure 4 shows that the three-dimensional exploded view of visible light laser designator of the present utility model.
Cross section view after the visible light laser designator assembling that Figure 5 shows that Fig. 4 is finished.
Now see also shown in Figure 3ly,, all need after encapsulating the recomposition laser diode and make its application limited and make over the conventional laser diode crystal particle in view of the past die process can not directly make outside laser diode crystal grain is exposed to.Of the present utility model being characterised in that, laser diode crystal grain 31 is bonded on the pedestal 33, directly be bonded on the heat radiating metal plate 32 of a large volume in exposed mode again, to increase the efficient of its heat radiation, this heat radiating metal plate 32 and as the utmost point of laser diode, in another district of heat radiating metal plate 32, utilize megohmite insulant that another conductive pad 34 is bonded in heat radiating metal plate 32 surfaces in addition, again by the routing mode, laser diode crystal grain and conductive pad are made electrical couplings, again by conductive pad 34 welding electrical wires, it can be connected with external power source, this is another utmost point of laser diode, and so the visible laser diode that forms needn't can directly be used on the optical devices such as light projector and alignment clamp through the encapsulation formality again and use.
Shown in Fig. 4,5, visible laser diode 3 of the present utility model is arranged in the sleeve pipe 41, wherein the shape of heat radiating metal plate 32 can change with shape, the length of sleeve pipe, but the connected mode that it is basic, promptly to be bonded in the characteristic that directly is bonded on the heat radiating metal plate in exposed mode again behind the pedestal then consistent for laser diode crystal grain.According to the principle of visible light laser designator, its sleeve pipe the place ahead (that is visible laser diode the place ahead) must be provided with a lens combination 42, so that the light that visible laser diode 3 is sent produces the effect that focuses on.The battery (not shown) of power supply then is electrically connected with the heat radiating metal plate 32 of visible laser diode 3, for stress the optical diode power supply.
Visible light laser designator of the present utility model shown in Figure 4 has the control circuit board 43 of the illumination mode of a control visible laser diode 3.But clearly, this circuit board 43 is not indispensable element.Its selection need be decided on demands of applications.But because visible laser diode 3 is because of sealing, so its volume can be reduced to minimum, so also can not occupy too big volume even add circuit board 43.As the assembling mode of Fig. 5, circuit board 43 directly frame above metallic heat radiating plate 32, so the volume of combination like this is reduced than traditional approach.
In the present embodiment, because laser diode crystal grain directly is bonded on the pedestal in exposed mode and its size is about 0.1mm, therefore the visual application of volume of heat radiating metal plate and only need 1mm (10 times) can reach the demand of heat radiation, therefore therefore the volume of whole visible laser diode can reduce, and then provides some to need the special applications of small size.
In another embodiment, circuit board 43 can be set to AVC (automatism voltage control), ACC (automatic current control) or APC (automated power control).And when the application of APC, then need an additional device for testing light, this device for testing light can be positioned on the circuit board or on the heat radiating metal plate.The only about 0.1mm of the size of this device for testing light is so the whole still more traditional indicator of size that constitutes is little.
The foregoing description only is explanation principle of the present utility model and effect thereof, and unrestricted the utility model, therefore, practises the modification of the foregoing description being made in the personage of this skill and changes still without prejudice to spirit of the present utility model.
