Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As schematically shown in Figure 1, 2, a kind of video camera head lamp, it includes main parts size such as lamp body 1, light shield 2, anti-explosion cover 3, reflector 4, lamp socket 5, bonnet 6, support holder 7, time-delay mechanism 8, power switch 14, power lead 13, lamp body 1, light shield 2 adopt metal material or plastic material to make the cover tubular, wherein the sleeve diameter of light shield 2 is bigger a little than the sleeve diameter of lamp body 1, and be the cooperation shape, light shield 2 can be socketed on the lamp body 1, the telescopic moving before and after making.Can not deviate from order to make light shield 2 on lamp body 1, stretch slippage better, the circumferential surface of lamp body 1 at its front end position has many slotted holes 9 as louvre, present embodiment has adopted 6 slotted holes, slotted hole 9 is evenly distributed on the circumferential surface at lamp body 1 front end position, being toroidal shape distributes, select two slotted holes, the 9 double pilot holes of doing that are distributed in lamp body two side positions simultaneously for use, the inboard at light shield 2 cylindrical shell positions is fixedly connected with separately slide block 10 in two positions of level respectively with screw, two slide blocks are established relatively, and each slide block 10 to be plugged in the pilot hole of two horizontal levels be 9 li of the slotted holes of strip, make light shield 2 scalable being socketed in movably on the lamp body 1.The front end of light shield 2 anti-explosion cover 3 that has been threaded, inner ring at anti-explosion cover 3 is fixed implosion guard with collar, make extraneous foreign matter be not easy to enter into lamp body 1 the inside, and the bulb of lamp body the inside is blasted exactly, also can not make the glass fragment of the bulb anti-explosion cover that directly flies out, cause casualty accident.
As Fig. 1,2 illustrate, in addition, on lamp body 1 and the light shield 2 many concave-convex type grooved rails 18 are arranged respectively, cooperation by the concave-convex type grooved rail, make light shield 2 can be optionally flexible slippage on lamp body 1, because having certain degree of tightness between the concave-convex type grooved rail 18 cooperates, make light shield 2 can be more stable on lamp body 1 positioning and fixing live, in order to make light shield flexible more firm, stressed more even, concave-convex type grooved rail 18 numbers adopt 6, and be on the belled position surface that is evenly distributed between lamp body and the light shield, concave-convex type grooved rail number can be made some adjustment according to actual needs certainly, makes the concave-convex type grooved rail can play beauty function, can play simultaneously the surface area that increases lamp body, improve radiating effect.
As schematically shown in Figure 1, 2,1 li cavity of lamp body has lamp socket 5, the hydraucone of lamp socket 5 front ends and the rim of a bowl one of reflector 4 are reinstated collar and are lived at lamp body 1 oral area internal fixation, bulb 12 has been installed in lamp socket 5 centers, reflector 4 is set in the bulb outside, bulb 12 is connected with power switch 14 on being placed in lamp body bonnet 6 by lamp socket and connecting line, and power switch 14 is connected with the external power supply battery by power lead 13 again.In order to prevent to turn on light; bulb is lighted quickly; make the operator of video camera be difficult to adapt to light environment at once; so in present embodiment; in lamp body 1 the inside time-delay mechanism 8 is installed; time-delay mechanism 8 is connected between bulb and the power switch; this time-delay mechanism can adopt various delay circuit modules; the deviser can design easily with reference to some traditional technology books; here just no longer in depth describe and inquire into; it makes lamp can light bulb at leisure when opening, and can play the effect of protection battery and bulb like this, and the eyes to the camera operation person play a very good protection simultaneously.Lamp body 1 is fixed with above the bonnet 6 at it and is used for the light emitting diode 11 that display power supply is about to exhaust, diode 11 is connected by on connecting line and the power control circuit, when the voltage that detects battery when power control circuit drops to certain level, trigger pip, come conducting diode, the electric energy that shows battery is about to exhaust, and must perform the preparation of cutaway as early as possible.
As Fig. 1,2 illustrate, lamp body 1 bottom is connected with support holder 7, support holder 7 tops and lamp body 1 are to adopt adjusting bolt 15 to link together, this connection is a kind of rotating connection, in the time will regulating the luffing angle of head lamp, as long as pull lamp body 1, it is just passable to make it turn to proper angle, can regulate bolt 15 once by pine in the time of necessary, regulate the luffing angle of lamp body 1 again, and then tighten and regulate bolt 15, support holder 7 bottoms are provided with the head lamp are fixed on fixedly boots 16 and gib screw 17 on the video camera, make the head lamp fixing convenient.
The user mode of this kind video camera head lamp such as Fig. 4,5 signals, the operator is as long as stretch or pushing light shield 2, make light shield 2 can be positioned at some positions of lamp body 1 very reposefully, because the printing opacity mouth position of light shield 2 is different with the distance of bulb 12, nature can make the illumination projected area of head lamp different, thereby realize the illuminating area and the brightness of step-less adjustment head lamp, nature very easy to use.
