Abstract
The utility model discloses a brightness and focus adjustable lighting device for teaching demonstration, which belongs to the practical teaching double function lighting device which can adjust the brightness and can automatically control the focus distance of a self-control lamp and a slide lamp in an audio-visual education program and in painting and calligraphy learning. The utility model is characterized in that two symmetrical antennae which are sheathed with a glazing clip and arranged at both ends of a lamp holder are respectively inserted into two concave grooves which are symmetrically fixed on the edge of an outer lamp cover and on a cover of a transformer and are provided with two outward extending joints to form movable connection through a short pin, and the other side on the cover of the transformer corresponding to a joint is provided with a light changing switch. Therefore, the utility model has the advantages of novel structure, low cost and convenient operation, and can realize the projection and the adjustment of the brightness, the focal length and the direction with double function, etc.
Description
The utility model relates to a kind of audio-visual education programme, practicality teaching brightness, roll adjustment automatic control platform, unreal dual-purpose lamp that the study painting and calligraphy are adjustable of being applicable to.
Though existing desk lamp and magic lantern are of a great variety, desk lamp after all is a desk lamp, and magic lantern is also only done projection and used.And some magic lantern structure is very complicated, and the cost of manufacture height certainly will influence and apply.Is exactly an example wherein as Chinese patent with notification number CN2148342Y disclosed " brightness auto-controlled electric focusing type projector ".
The purpose of this utility model just is the function combinations with desk lamp and magic lantern, design a kind of simple in structure, cheap, realize projection, brightness, focal length, the platform that direction is adjustable, unreal dual-purpose lamp.
The purpose of this utility model is realized by following technical proposal: this, unreal dual-purpose lamp comprise the ball-type bulb and in, outer semi-circular lampshade, transformer and case thereof, glazing clip and insert its card in glass plate, the spiral shell lamp, attaching plug and lamp socket, its feature is being set with a glazing clip and inserting respectively to be fixed in the overhanging concave groove of each symmetrical on outer lampshade edge and the transformer case two joint with the fastening antenna lamp bracket two ends of screw and selling into flexible connection by short of two symmetries, and opposite side corresponding with joint on the transformer case is provided with dimmer switch.
Ball-type bulb and inside and outside semicircle lampshade thereof can be sold left-right rotation by the weak point in inserting joint.
The antenna lamp bracket both can be sold left-right rotation around solid weak point in the top connection of transformer case again by flexible its length that changes of antenna.
Glazing clip can be done upper and lower slip by unscrewing screw on the antenna lamp bracket.
Taking off glass plate is exactly desk lamp.
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model side-looking.
As shown in the figure: 1, ball-type bulb, 2, transformer, 3, glazing clip, 4, insert the interior glass plate (white of clamp, thick is cmm), 5, screw, 6, joint (upper and lower, forward and backward totally 4), 7, antenna lamp bracket (forward and backward symmetrical totally 2), 8, dimmer switch (upward be high light, in for closing, be down the low light level), 9, interior lampshade (for black sandblasts not reflective), 10, outer lampshade (moulding firmly), 11, attaching plug, 12, lamp socket.
Before and after the right side edge of outer lampshade 10, respectively be fastened with the joint 6 that an over-hang part is divided into side formula concave groove symmetrically, front and back, right side adjacent with its center on transformer 2 cases respectively are fastened with a joint 6 identical with the said structure position symmetrically, being set with a glazing clip 3 and inserting respectively in the concave groove of 4 upper and lower, forward and backward joints 6 of two symmetries with screw 5 fastening antenna lamp bracket 7 two ends, and, make it into flexible connection with 4 short pin difference pinnings.Therefore, ball-type bulb 1 and interior outer lampshade 9,10 thereof can be around short pin left-right rotation, and same antenna lamp bracket 7 can be around short pin 6 left-right rotation of bottom, and the length of antenna lamp bracket 7 then changes with telescopic antenna.Transformer 2 is fixed on the lamp socket 12, and its extension line passes antenna lamp bracket endoporus and is connected with lamp holder, simultaneously has extension line to be connected with attaching plug 11 in addition, is provided with dimmer switch 8 in the left side of transformer 2 cases, its extension line be connected fixture wire and join.White glass plate 4 is that the bayonet socket of insertion glazing clip 3 is interior, and glazing clip 3 usefulness screws 5 are fixing, unscrew screw 5, and glazing clip 3 can be done upper and lower slip on antenna lamp bracket 7, to regulate the size of projection.Load onto glass plate 4 magic lantern, take off 4 of glass plates and become desk lamp.
Its use and method thereof are: at first by plug 11 energized, press dimmer switch 8, bulb 1 is bright, white glass plate 4 is installed in the bayonet socket of glazing clip 3, the painting and calligraphy film that will describe or the transparent scraps of paper is placed on the glass plate 4 again; Then, under water writing paper or blank sheet of paper be layered on, and, the location is regulated on lamp, glass, paper and projecting plane by the painting and calligraphy size requirements of being described, can the painting and calligraphy exercise and use.If want to put painting and calligraphy greatlyyer, then platform, unreal dual-purpose lamp are put on the table, paper is layered on the ground gets final product; Or sticking on the wall paper, lamp is made 90 degree to the right rotate, be projected on the wall and describe, go back the distance between translational table, unreal dual-purpose lamp and wall, to reach projected size and the effect of oneself wanting.Also platform, unreal dual-purpose lamp can be put in the drawer, put a glass on the table and make it exceed desktop 20-30cm, the character library that practise is placed on glass, put paper above again, light just can have been practised from bottom to top.
Take off glass plate 4, just become desk lamp.
In sum, the utlity model has novel structure, cheap, practical, use Convenient, with simple member realized projection, brightness, focal length, direction is adjustable, a lamp is dual-purpose etc. Advantage and disadvantage.
