Abstract

The utility model discloses a portable multipurpose lamp, which can be used as spotlights, fluorescent lamps, long wave ultraviolet lamps, and short wave ultraviolet lamps. The inner face of the outer casing of a cuboid is fixed with fluorescent tubes which can rotate more than 180 DEG along with a lamp cover and can be fixed on the rotating optional position via a fastening device. A long wave ultraviolet lamp tube and a short wave ultraviolet lamp tube are respectively mounted on a cover plate inside the box and the bottom plate of the box. The three lamp tubes are supplied with the electricity by an electronic oscillation circuit mounted inside the box. flashlamps mounted on the other end of the inside of the box conduct the light condensing via a focusing mechanism. The utility model is directly supplied with the electricity via the dry batteries of the public power inside the box.

Description

Portable multipurpose lamp

The utility model relates to a kind of light fixture of multi-purpose, and it can be used as simultaneously, and baby spot is used, fluorescent lamp is used, the long wave ultraviolet lamp is used, short wave ultraviolet lamp usefulness, and its power supply is No. 1 batteries of five joints, also can connect 6

-12

Use on the power supply.

Current public security department employed illuminating lamp and inspection lamp in executing the task in the scene of reconnoitring all are single uses, especially in field work at night, portably use all inconvenient.

Task of the present utility model is to provide a kind of multi-functional comprehensive light fixture in convenient multi-purpose way that portably uses to public security department, is particularly suitable for not having the area and the field condition use of reconnoitring and execute the task at night of civilian electricity.

Task of the present utility model is finished in such a way: the profile of lamp body is the plastic casing of a cuboid, long 35 centimetres, wide 10 centimetres, high 9 centimetres, save No. 1 battery as public power with five, there are four switches controlling four different lamps, also having a switch is the converter circuit master switch, supply with the power supply of the 6.3V bulb of band convergent bowl, be that dry cell is directly supplied with by the gauge tap on the shell, this converter converts low-voltage DC to power supply that high voltage is similar to square wave and excites lamp luminescence, if when using external power supply, circumscripted power line can be inserted in the socket on the lamp body, the internal electric source automatic disconnection, external power supply is then connected with way circuit.

Below with reference to accompanying drawing this lamp is described in further detail.

General assembly drawing when Fig. 1 light cover is opened to 90 ° of angles of lamp body.

Fig. 2 dismantles behind loam cake, the inter panel, the lower casing installation diagram.

Fig. 3 A is to lamp body front end face view.

Fig. 4 circuit theory diagrams.

With reference to Fig. 1: the spotlight bowl of a band cover plate (1) is installed in the end in the plastics lamp body, stretch into the small electric bulb (2) of a 6.3V in the lamp bowl (1), small electric bulb (2) is spun on the electric bead block of focus adjusting mechanism (3), and connected the power circuit of switch (14) control that is subjected on the shell (8), steamboat (36) small electric bulb (2) that rotates on the focus adjusting mechanism (3) just can move forward and backward stably, plays focus effect.Place the standby circumscripted power line (28) of one section band plug in the back of focus adjusting mechanism (3).Upward fix a long wave ultraviolet fluorescent tube (15) at plastic cover plate (16) by lamp base (17), short wave ultraviolet lamp (7) is fixed on the following lamp body shell (8) of cover plate (16), fixing converter circuit master switch (37) on the cover plate (29), long wave ultraviolet lamp switch (21), short wave ultraviolet lamp switch (22), switch for fluorescent lamp (23) and potentiometer (38).Be opened and fixing reflector (33) and daylight lamp base (32) fluorescent tube (24) on 90 ° light cover (31) inner surface, on lamp body shell (8) wall external electric supply socket (9) is housed, the turning cylinder supporting part (19) (26) that two light covers are arranged on the shell (8), by screw (18) (25) nut (20) wing nut (27) light cover and shell are linked up, be noted that especially wing nut (27) also plays a part fixedly light cover position.One plastic handles (34) is arranged on the shell (8).With reference to Fig. 2 is that dismantle light cover (31) and inter panel (16) five No. 1 batteries of joint (4) of dismantling are arranged by spring (5) and spring base (6) branch two and are fixed in the box.Be fixed on the circuit board (35) on the shell (8) coil transformer (10) resistance (11) is installed, large power triode (13) electric capacity (12), with reference to Fig. 3, this is that the front elevation of prefocus cap can be seen small electric bulb (2) across protective glass plate (30).With reference to Fig. 4, this is the converter circuit schematic diagram, and triode among the figure (13) emitter stage links to each other with positive source by switch (37), and coil L1 head end joins in colelctor electrode and the transformer (10), base stage and biasing resistor (11) join, and simultaneously and electric capacity (12) join.Electric capacity (12) other end communicates with the coil L2 tail end of transformer (10).Potentiometer (38) is a base stage tuningout leakage resistance, and its two ends join with resistance (11) one ends respectively, and the primary coil center head of the other end and transformer (10) joins.Coil L1, L2 in triode (13) transformer (10) and electric capacity (12) constitute the inductance of three-point oscillating circuit.Electric capacity (12) and coil L1, L2 are timing element decision frequency of oscillation.The light a lamp usefulness of pipe (24) (15) (7) of oscillator signal feed point after the more secondary coil L3 of the number of turns that ferrite 17 lotus roots are bonded to transformer (10) boosts.All the other element switch (14) are connected back and are received both ends of power and form the spotlighting control circuit with spot light lamp bulb (2).Switch (37) is connected between transistor emitter and the positive source, stopping and working in order to the control oscillating circuit.Fluorescent tube (24), be parallel to the two ends of the secondary coil L3 of transformer (10) after long wave ultraviolet fluorescent tube (15) and short wave ultraviolet fluorescent tube (7) are in series with switch (23) (21) (22) respectively, constitute independently to start separately and extinguish control circuit.

During operation, it is bright to open switch (14) small electric bulb (2); Open converter circuit master switch (37) earlier, it is bright to turn on switch (21) long wave ultraviolet lamp more successively; It is bright to turn on switch (22) short wave ultraviolet lamp; It is bright to open switch (23) fluorescent tube, and brightness can be regulated by potentiometer (38).
