Abstract
The utility model relates to an utilize profection lamp of meniscus lens spotlight. A LED core pearl base section of thick bamboo in central point put and be equipped with LED core pearl, correspond the position with LED core pearl center in the LED core pearl base section of thick bamboo and locate the centre gripping and have concavees lens, spotlight focusing sleeve, a LED core pearl base section of thick bamboo between twist mutually through screw thread and connect, spotlight focusing sleeve one end be equipped with convex lens. The utility model discloses simple structure, low in cost, be applicable to throwing of building spotlight, in order to avoid arousing because of LED core pearl chip size is great that the spotlight effect reduces, characteristic that the product design utilized the concavees lens formation of image to reduce installs a set of concavees lens piece additional and has realized good spotlight effect between LED core pearl and collector lens.
Description
Technical field
This utility model relates to a kind of delineascope utilizing meniscus optically focused.
Background technology
At present, needing to reach spotlight effect in outdoor building lighting, many employing Metal halogen lamps combine investigation on several focus reflectors to be carried out
The focus irradiation of light, due to the restriction of reflected device manufacturing technology, optically focused angle is difficult to minimum, in practice, does not has
Having light source is real point source, even if LED core pearl is the least, it still has physical dimension.As long as although make lens and
Being at a distance sufficiently large between LED core pearl, it is possible to LED core pearly-lustre source as point source, but thus also result in outside light fixture
Shape size can be the biggest.Owing to LED core pearly-lustre source tool has the dimensions, the most theoretic point source, enters using lens
In row optically focused, along with LED core pearl power increases (size increases the most therewith), spotlight effect also can reduce, be difficult to accomplish 9 degree with
Under.
Summary of the invention
The purpose of this utility model is to provide a kind of delineascope utilizing meniscus optically focused, thus overcomes in background technology
Pointed drawback.
This utility model solves its above-mentioned technical problem and is used following technical scheme: one utilizes meniscus to gather
The delineascope of light, it is mainly configured with: LED core pearl, concavees lens, convex lens, optically focused focusing sleeve, LED core pearl pedestal cylinder, described
LED core pearl pedestal cylinder in center be provided with LED core pearl, press from both sides with corresponding position, LED core pearl center in LED core pearl pedestal cylinder
Hold concavees lens；Screw thread screw thread phase twist-on is passed through in described optically focused focusing between sleeve, LED core pearl pedestal cylinder；Described optically focused
Focusing sleeve one end is provided with convex lens.
Virtual imaging LED core pearl is formed by setting focal length between above-mentioned LED core pearl and concavees lens.
The beneficial effects of the utility model: simple in construction, cheap, be applicable to the projection of building optically focused；In order to avoid
Because LED core pearl chip size causes more greatly spotlight effect to reduce, product design utilizes the characteristic that concavees lens imaging is reduced, at LED
Install one group of concace mirror lens between core pearl and collecting lens additional and achieve good spotlight effect.

Fig. 2 is a kind of delineascope optics principle schematic utilizing meniscus optically focused of this utility model.
1-LED in figure, 2-imaging LED, 3-concavees lens, 4-convex lens, 5-optically focused focusing sleeve, 6-LED pedestal cylinder.
Detailed description of the invention
Detailed description of the invention of the present utility model is made a detailed explanation by 1-2 below in conjunction with the accompanying drawings.
Embodiment: a kind of delineascope utilizing meniscus optically focused, it is mainly configured with: LED core pearl 1, concavees lens 3, convex
Lens 4, optically focused focusing sleeve 5, LED core pearl pedestal cylinder 6, in described LED core pearl pedestal cylinder 6, center is provided with LED core pearl
1, it is clamped with concavees lens 3 with corresponding position, LED core pearl 1 center in LED core pearl pedestal cylinder 6；Described optically focused focusing sleeve 5,
By screw thread screw thread phase twist-on between LED core pearl pedestal cylinder 6；Described optically focused focusing sleeve 5 one end is provided with convex lens 4.
Virtual imaging LED core pearl 2 is formed by setting focal length between described LED core pearl 1 and concavees lens 3.
This utility model core is: by concavees lens 3, LED core pearl 1 optically focused forms virtual imaging LED core pearl 2, warp
After crossing concavees lens 3, light dissipates outward so that forming the preferable point source of effect, the point source of formation passes through convex lens again
Its light is projected away by 4.According to the difference of light projection distance, can be by adjusting gathering between concavees lens 3, convex lens 4
Light focusing sleeve 5, it is achieved the adjustment of zoom.And the virtual imaging LED core pearl 2 formed between LED core pearl 1, concavees lens 3 is one
Individual fixing imaging, when therefore dispatching from the factory, just by fixed clamp, need not adjust.
