Abstract

The utility model provides a new telecontrol lamp device with adjustable irradiating directions, which is characterized in that the radial direction of a reflector 2 is also provided with half shafts 17 of the reflector. A half shaft is also provided with a worm gear 16 which is engaged with a worm 15. The worm 15 and a reflector 3 are driven by a motor 12 via a worm wheel 13 and a connecting shaft 14 to change angles. The device is characterized in that the vertical angle change of a light source is controlled by the worm gear and the worm which act directly on the reflector to finish deceleration and the irradiating angle change of the light source. The change of two degrees of freedom of the light source is remotely controlled by the tilting of a controller mandrel which keeps a contact retaining closed in various forms.

Description

Telecontrol lamp with adjustable irradiating direction

The utility model relates to a kind of improved remote control lighting, particularly a kind of light fixture that can the adjustable direction of illumination of remote control.Be applicable to vehicle, boats and ships and industrial and mineral projection illumination.

Projection illumination light fixture on the domestic market all is to adopt artificial the rotation to adjust direction of illumination basically at present.Use cumbersomely, the installation site also is restricted.The projection illumination light fixture of external now existing remote control appears on the market, and the variation of its light source position adopts motor deceleration control link mechanism to finish more, and its electronic control circuit is also comparatively complicated.

The purpose of this utility model provides a kind of improved remote control lighting, its fitting structure compactness, reliable, and controller adopts single button mandrel method of tilting that the contact is closed and opens, thereby with the projecting direction of simple line traffic control mode conversion lamp light source.

Solution of the present utility model is such: the plane rotation of light fixture is slowed down by a motor and is driven a great wheel, makes the light source bracket that is contained on the great wheel do the plane rotation.The vertical direction change of light source is by the another motor that is contained on the light source bracket, paying the back drive of slowing down through first-stage worm gear is contained on the speculum semiaxis another worm gear pairs is slowed down again, and drive the speculum semiaxis and speculum rotates, to change the vertical irradiation angle of light source.

Adopt the second-stage worm gear worm-drive, pivoting moment is acted directly on the speculum semiaxis, save linkage thereby drive the speculum rotation, and because the self-locking action of worm and gear transmission, guaranteed the locking of light source position, so simple in structure, the anti-vibration ability also increases.

The controller of this programme is following formation: the top of garden shape button mandrel is fixed on elastic cup central authorities, and its bottom connects the fixed head of a movable contact, and mandrel lower end bellmouth is supported on the spur of stationary contact fixed head central authorities.As long as press garden shape button and the edge quiet, that movable contact is corresponding, just can make closure quiet, that movable contact is made eight kinds of states owing to prop up the inclination of contact fixing plate, thus the variation of two frees degree of control lamp light source.It is simple in structure, and reliable reciprocal interlocking performance is arranged between the easy to operate contact.

Embodiment of the present utility model can be illustrated in conjunction with the accompanying drawings.

Fig. 1 is the light fixture positive view of this programme.

Fig. 2 is this programme controller longitudinal sectional view.

With reference to Fig. 1, a light fixture inner structure that is installed in the Transparent lamp shade 1, its plane rotating mechanism is to drive worm-gear toothing assembly 9 by the worm screw on the motor 11, and the great wheel 8 that is installed on the main shaft 10 is given in transmission, does the plane rotation thereby drive the light source bracket 5 that is contained on the great wheel 8.

Motor 12 on the light source bracket 5 drives worm gear 13 and connecting axle 14, thereby make worm screw 15 and and then rotation of worm gear 16, because worm gear 16 is contained on the speculum semiaxis 17, so speculum 2 and light source 3 also rotate slowly around the axle center of speculum semiaxis 17, thereby change the vertical irradiation angle of light source 3.

The power supply of motor 12 and light source 3 transports for the brush group 6 that is contained on the great wheel 8 by conducting ring 7 conduction.The angles shifts limit of speculum 2 is adjusted cam limit switch 4 controls of angle.

Fig. 2 is the longitudinal sectional view of controller 18.

With reference to Fig. 2, garden shape button 18-1 and mandrel 18-2 mould cast solid, the upper end of mandrel 18-2 is fixed in the centre bore of elastic cup 18-5, the outer rim of elastic cup 18-5 is fixed on the shell 18-3, riveting has four movable contact 18-4 on four jiaos of rhombus movable contact fixed head 18-7, its centre bore is fixed on mandrel 18-2 lower end, the bellmouth of mandrel 18-2 lower end is supported on the spur 18-9 at following stationary contact fixed head 18-8 center, and the bellmouth tapering should add that mandrel 18-2 gradient multiply by 2 greater than spur 18-9 tapering.Space between stationary contact 18-6 and the movable contact 18-4 should meet electric clearance and require and keep equal distance.Elastic cup 18-5 radially can make ripple river in Shangdong Province shape, can recover plumbness immediately so that each contactor gap is normal to guarantee mandrel 18-2 after external force is eliminated.

As long as press the corresponding with it sound contact, edge of garden shape button 18-1 during use, just can make this group closing of contact, as pressing the corresponding points between two groups of contacts, these two groups of contacts are just closed simultaneously, but the situation of three groups of above closings of contact will never occur, so also just guaranteed the interlocking of control.Use the controller 18 just can be, promptly as long as change motor steering and whether switching on just can be finished the control to two frees degree of lamp light source direction of illumination with simple circuit.
