Description
Technical field
The utility model relates to projection light fixture device technique field, refers in particular to the adjustable projection lamp of a kind of focal length.
Background technology
The set of lenses of existing projection lamp adopts fixing structure often, and the distance between light source and lens is non-adjustable, and like this, it is best that the display effect when projected image is difficult to reach.In addition, single lens can be very limited at the focal length in when projection and the adjusting of spot size, in view of this, are necessary that the structure of improving existing projection lamp improves this situation.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point of the prior art and a kind of projection lamp that adopts doublet to focus is provided.
The purpose of this utility model can reach by the following technical programs: a kind of projection lamp, include: electrical appliance kit and lamp cartridge module, openend at the lamp cartridge module is provided with transparency, openend at the lamp cartridge module is connected with the light modulation cylinder, on the barrel of light modulation cylinder, have the skewed slot of two symmetries, interior set of lenses is built in the cavity of light modulation cylinder, and two lock-screws are connected with interior set of lenses after passing respectively corresponding skewed slot; Outward opening end at the light modulation cylinder is provided with the outer lens group, and the outer lens group is fixedly connected with an end of sliding bar, and the other end of sliding bar is socketed in circular hole corresponding on the light modulation cylinder and is screwed.
Openend at described lamp cartridge module also is provided with the transparency retainer ring coordinated with transparency.
Between described transparency retainer ring and light modulation cylinder, also be provided with anti-dazzling screen, anti-dazzling screen guide collar.
Described light modulation cylinder is connected to the openend of lamp cartridge module by light modulation cylinder fixed head.
Between described interior set of lenses and described outer lens group, be provided with filter.
Described electrical appliance kit is for inhaling the top electrical appliance kit, and the top of electrical appliance kit is fixedly connected on ceiling, and the bottom of electrical appliance kit is flexibly connected by linking arm and the rotating shaft of lamp cartridge module.
After adopting said structure, the light source of this new embodiment, after the reflector luminous intensity distribution, by after two groups of set of lenses, realizing uniform light distribution, and can increase transparency and forms needed shape or LOGO before interior set of lenses.Interior set of lenses, by rotational slide in the skewed slot on the light modulation cylinder, realizes adjusting focus, after completing, lock screw is fixed; The outer lens group connects sliding bar, in the circular hole on sliding bar side on the light modulation cylinder, is free to slide and coordinates the outer lens group to adjust light state and spot size.As from the foregoing, this is novel has the succinct structure of profile and understands, practicality simple to operate, and the adjustable range of two groups of lens is wide, the characteristics that drop shadow effect is good.
