At present, domestic project machinery LED portable lamp is generally carry out by reflector or lens the irradiating angle that secondary light-distribution reaches required.The advantage that reflector compares lens is, reflector body material than lens position, can be applicable to rugged environment more under high temperature and low temperature, and as born the high temperature of more than 200 DEG C, lens then can not; Lens are relative to the advantage of reflector, luminous intensity distribution efficiency high (lens only adopts the mode of refraction, and light loss is little, and reflector adopts the mode of reflection, and in reflection process, a part of light can be absorbed).
Lens luminous intensity distribution divides again two kinds of modes: one is monoblock type, and another kind is split type.Monoblock type is by lens and PC face shield integrally, mould one-shot forming, good integrity, and light transmission is good, but with high costs, even higher than the cost adopting reflector to carry out secondary light-distribution; Split type is be fixed on PC face shield by single lens by the mode of glueing joint, this mode is relative to reflector and monoblock type lens, although save the cost of die sinking, but it still has certain limitation, in vibrations or when being subject to external shock, lens likely come off from PC face shield, cause LED portable lamp to occur quality problems.
In addition, existing LED portable lamp can only select a kind of mode in reflector or lens, as being modified to another way, must change other parts simultaneously.
Utility model content
Technical problem to be solved in the utility model is, when providing one to select split type lens to carry out secondary light-distribution, in vibrations or when being subject to external shock, lens can not come off, meanwhile, can also by the LED portable lamp selecting different lens to come satisfied different irradiation distance and range of exposures requirement.
The technical problem that will solve further is, provides a kind of feature in conjunction with lens and reflector, reflector or split type lens can be selected to carry out the LED portable lamp of secondary light-distribution according to environment for use.
The utility model solves the technical scheme that its technical problem adopts: a kind of LED portable lamp, comprise lamp housing, circuit board is provided with in described lamp housing, described circuit board is fixedly connected with lamp housing, described circuit board is provided with LED lamp bead, described lamp housing is provided with clamp plate type lens, described clamp plate type lens comprise lens clamp and single lens, described lens clamp is respectively equipped with two barbs and two location circular arcs in the fixed position of single lens, described two barbs are 180 ° of layouts, described two location circular arcs are 180 ° of layouts, described two barb place center lines and two locate circular arc place central axis, described single lens be provided with flange foremost, described single lens are by the barb assembly connection on flange and lens clamp, the front end of described lamp housing is provided with printing opacity protective cover, the back side of described lamp housing is provided with electric connector seat, and the lower end of described lamp housing is provided with mounting bracket.
Further, described circuit board is the aluminum base circuit board be connected with constant-current drive circuit.
Further, described aluminum base circuit board is fixedly connected with lamp housing by screw.
Further, described printing opacity protective cover is PC face shield.
Further, the inner side of described PC face shield is provided with waterproof pad, and the outside of described PC face shield is provided with pressing plate, and described lamp housing, waterproof pad, PC cover and pressing plate are screwed connection.
Further, described PC face shield is connected and fixed and dustproof and waterproof by the mode of encapsulating and lamp housing.
Further, the installed surface of described lens clamp is to the distance of single lens and LED lamp bead cooperation place (being namely arranged on the minimum point of lens on lens clamp), identical to the distance of reflector and LED lamp bead cooperation place (i.e. reflector minimum point) with the installed surface of reflector, wherein, the installed surface of reflector and the installed surface of lens clamp are same position.
The utility model lens are single lens, have the light distribution angle of all size, are standard component, this kind of split type lens, adopting barb fixed lens, can not come off when being given a shock and impact, solve the hidden danger of quality existed by lens adhesive technology, improve the practicality of LED lamp.Further, utilize the utility model, the versatility of housing, LED module and other parts can be improved, reduce production cost.
