Description

A kind of double end spotlight

Technical field

The present invention relates to a kind of special lamp of video display stage illumination, lighting, be meant a kind of double end spotlight lamp especially.

Background technology

The spotlight of using when video display stage arenas is performed at present is single-lens light fixture mostly, can adorn Fresnel lens, plano-convex spherical lens, the plano-convex non-spherical lens.Each lens packed into make a kind of light fixture in the lamp body, because the various index of refraction in lens are different, the radiation response difference when performance, is changed different lamps as required, makes troubles to the staff like this.Every kind of lens light fixture of packing into, the light efficiency difference just needs to be equipped with various light fixtures, has strengthened user cost.

Summary of the invention

The object of the present invention is to provide a kind of double end spotlight, by at the lamp body two ends different lens being installed respectively, utilize reflector support Rotate 180 °, reflector rotates 180 ° thereupon, becomes a kind of light fixture with lens, combination of light sources; With reflector support Rotate 180 °, reflector also rotates 180 ° thereupon, becomes another kind of light fixture with other end lens, combination of light sources again.

The objective of the invention is to realize by following technical scheme, it comprises lamp body shell, base end cap, lens trim ring, lens, focusing component and light source part, a base end cap is installed at lamp body shell two ends respectively, the side of covering installs lens respectively in the two ends base end, all fix, be combined into lamp body with the lens trim ring.

Focusing component is made of guide rod, adjusting screw(rod), adjusting knob, guide pin bushing, guide rod and adjusting screw(rod) pass corresponding guide pin bushing respectively, and the guide rod two ends are fixedly connected on two base end caps, and two base end caps are respectively established an adjusting knob outward, link to each other with the adjusting screw(rod) two ends respectively, use as the two ends focusing.

Light source part is made up of runner assembly and fixation kit, runner assembly is propped up by hand button, dwang, connecting plate, reflector and is configured to, dwang passes the location cushion cover, its upper end is affixed with connecting plate, connecting plate and reflector support bottom surface are spirally connected and are that one, dwang lower end pass lamp body shell lower shoe and link to each other with the hand button; Reflector is installed on the reflector support.

Fixation kit is made of sliding support plate, reference column, lamp socket backing plate, and screw passes lamp socket backing plate, reference column from top to bottom, and being spirally connected with the slip underneath gripper shoe is one; The top of location cushion cover is fixed on the sliding support plate, and sliding support plate is passed in the bottom, is fixed on the guide pin bushing below the sliding support plate; Light source part is regulated slip thereon by guide pin bushing.

Described reflector support is the L type, establishes projection and three holes on its bottom surface.

Be provided with the rectangle notch below the described connecting plate, the rectangle projection set with the dwang upper end matches, and the connecting plate middle part is fastening with screw with the dwang upper end;

Three holes of establishing on the described connecting plate on three holes and the reflector support bottom surface are spirally connected, and become rotating one.

Be provided with two symmetrical U type notches below the described lamp socket backing plate, with the protruding corresponding engaging on the reflector support.When the reflector support rotates to 180 ° of location, the openhanded hand button of opening, the spring examination is put, and the projection on the reflector support snaps in a U type notch, arrives the location.

Be provided with groove in the cushion cover of described location, spring is installed in the groove, and is sleeved on the dwang upper end.

Described reference column is two, is located at sliding support plate one side.

Described two ends lens all can be Fresnel lens, plano-convex spherical lens or plano-convex non-spherical lens.

Described lamp socket is packed in does not do rotation on the lamp socket backing plate, have only before and after the reflector support Rotate 180 °, and reflector on it and two ends set of lenses are synthesized the double end spotlight.End at double end spotlight of the present invention can be adorned Fresnel lens, and the other end can be adorned the plano-convex spherical lens.The light that Fresnel lens penetrates is soft, and plano-convex spherical lens effect is the illumination height, and hot spot is even, distance is established in throwing, and therefore application of the present invention is very extensive.

Advantage of the present invention is:

1, simple lens has become double lens, and original single illumination has been made into two kinds of irradiation functions.

2, realized a desk lamp how with, two ends irradiation, illumination is even.

3, energy savings, reduce cost, make things convenient for the user.
