Description
Technical field
The utility model relates to the technical field of searchlight, more particularly relates to portable floodlight projector.
Background technology
Traditional portable searchlight generally comprises cylindrical shell with portable handle, be contained in the housing front end and put illuminator and control circuit in transparency cover, operated by rotary motion has a gauge tap on the housing, control circuit generally adopts IC 4017 to carry out programme-control, as shown in Figure 1, be the portable searchlight control circuit schematic diagram of prior art, it is by weak extremely strong, again to this plurality of processes circulation of flashing, stopping by a gauge tap loop start control light on the housing.Adopt the portable searchlight circuit control of said structure and principle comparatively complicated, its circuit cost is higher, simultaneously owing to light needs be pressed by weak extremely strong circulation, when needs directly carry out high light or flash of light, need repeatedly press and to realize, it is not too convenient to use, as application number is 00239907, the applying date is on October 14th, 2000, denomination of invention is the patent application of Hand-held Anti-explosion searchlight, this patent disclosure a kind of Hand-held Anti-explosion searchlight, comprise a columnar housing, be contained in the printing opacity protecgulum of housing one end, be contained in the bonnet composite set of the housing other end, be equipped with the O RunddichtringO on the contact-making surface of described protecgulum and back lid arrangement and described housing, the control device of light-emitting device and the described light-emitting device break-make of control is housed in described housing, the searchlight that this patent provided removes to have well and prevents dust, waterproof, outside the withstand voltage explosion-proof performance, can also carry out the brightness regulation of searchlight, but have aforesaid defective equally.
Summary of the invention
The purpose of this utility model is exactly that provide for the deficiency that solves prior art a kind of has portable floodlight projector easy to use, that cost is low.
The utility model is to adopt following technical solution to realize above-mentioned purpose: this portable floodlight projector comprises the housing with portable handle, be built in the charge power supply in the housing, be contained in the transparency cover of housing front end and place transparency cover interior shot-light pearl and control circuit, this control circuit comprises the oscillating circuit that is connected with power supply, the shot-light power driving circuit, charging circuit and switch transition control circuit, the shot-light pearl is connected on the shot-light power driving circuit, the switch transition control circuit adopts strong and weak shelves two way control switch, weak gear switch connects the control oscillating circuit, oscillating circuit connects the shot-light power driving circuit, drive the work of shot-light pearl for the shot-light power driving circuit by the voltage that can modulate of oscillating circuit output, the prime time switch directly connects control shot-light power driving circuit, and corresponding housing is provided with prime time and weak gear switch button.
Described switch transition control circuit is to adopt operational amplifier IC and triode N1 to form conversion control circuit, is connected with low-voltage protection circuit between shot-light power driving circuit and switch transition control circuit.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is: owing to adopt the lower operational amplifier IC of price in the control circuit of the present utility model, each unit that uses same IC is by different periphery circuit design, realize different functions, cost is low; So simultaneously,, when the needs high light, directly press the prime time button and get final product, do not need to adopt a shift knob circulation to press repeatedly and just can finish as prior art owing to adopt strong and weak two switches, when needs flashing light duration can be realized by the high light button, easy to use.
