Abstract

The utility model discloses an optical structure of lamps and lanterns, including the light source that reflects light the cup with be located the cup cup inside cup and luminous direction orientation is reflected light that reflects light, still include concavees lens, concavees lens be located reflection of light cup one side and just to the rim of a cup of reflection of light cup. The utility model discloses an optical structure of lamps and lanterns can change lamp light source's focus point, makes the contained angle of light beam diminish the usable overall arrangement space of greatly increased lamps and lanterns function to in the costneutrality or when only increasing a small amount of cost, reach thermal -insulated effect.

Description

The optical texture of light fixture

Technical field

The utility model relates to a kind of optical texture, especially a kind of optical texture of light fixture.

Background technology

In general, as shown in Figure 1, the optical texture of modern stage lamp is made up of the reflector 10a and light source 20a through optimizing distortion.Light source 20a is positioned on the first focus f1a of reflector 10a, assembles formation second focus at the position glazing of f2a.The functional module of light fixture is placed in position suitable before and after the second focus f2a, due to more away from focus f2a, its spot diameter is larger, functional module is limited at one as in the B size in accompanying drawing 1 according to actual needs, but by the restriction of existing optical texture, the bulk causing the functional module of light fixture to use is comparatively narrow and small, thus has a strong impact on the development of light fixture.

Utility model content

For the deficiencies in the prior art, the purpose of this utility model is intended to the optical texture providing a kind of light fixture, thus increases the spendable arrangement space of light fixture functional unit.

For achieving the above object, the utility model adopts following technical scheme:

An optical texture for light fixture, comprises reflector and is positioned at the inner and light emission direction of reflector cup towards the light source of reflector, it is characterized in that: also comprise concavees lens, and described concavees lens are positioned at the side of reflector and are right against the rim of a cup of reflector.

The optic center point of described light source, reflector rim of a cup center and concavees lens is located on the same line.

Described concavees lens can be meniscus and biconcave lens.

The plated surface of described concavees lens is covered with thermal isolation film.

Compared to existing technology, the beneficial effects of the utility model are: it is by adopting the combination design of reflector, light source, concavees lens, the focus point of lamp light source is changed by concavees lens, the angle of light beam is diminished, greatly increase the spendable arrangement space of light fixture function, and do not increase cost or while only increasing a small amount of cost, reach heat insulation effect.

Detailed description of the invention

Below, by reference to the accompanying drawings and detailed description of the invention, the utility model is described further:

As shown in Figure 2, the optical texture of the utility model light fixture comprises reflector 10, be positioned at the inner and light emission direction of reflector 10 cup towards the light source 20 of reflector 10 and concavees lens 30, and described concavees lens 30 are positioned at the side of reflector 10 and are right against the rim of a cup of reflector 10.

The optic center point of described reflector 10 rim of a cup center, light source 20 and concavees lens 30 is located on the same line.

Described concavees lens 30 are on the right side of reflector 10 rim of a cup and between the functional module 40 of light fixture.

Described light source 20 is positioned on the first focus f1.The light that described light source 20 sends reflects through reflector 10, through concavees lens 30, finally converge at the 3rd focus f2', because concavees lens 30 have the function of divergent rays, therefore the second focus f2 that the light sent compared to light source 20 is directly converged to after reflector 10 reflects, 3rd focus f2' is farther from reflector 10, and beam angle D' is less compared to beam angle D when not adding lens, therefore greatly can increase light fixture arrangement space B'.

The plated surface of described concavees lens 30 is covered with thermal isolation film (not providing in accompanying drawing), the light emitted when light source 20 reflects through reflector 10, again by after concavees lens 30, described thermal isolation film can stop that the some ultra violet rays in described light enters the functional module 40 of light fixture, serves effect of heat insulation.

Described concavees lens 30 comprise concave surface and convex surface.The concave surface of described concavees lens 30 is towards light source 20, and the film plating layer of the convex surface of described concavees lens 30 can play the effect again reflected away of the reverberation of functional module, with protect light source and light cup unlikely overheated.

Therefore increase after plated surface is covered with the concavees lens 30 of thermal isolation film in light fixture, not only can increase the arrangement space B' of light fixture greatly, but also heat insulation and reflective effect can be played.

Wherein, in the present embodiment, described concavees lens 30 are meniscus.Certainly, except adopting meniscus, described concavees lens 30 can also adopt biconcave lens 31 (as shown in Figure 3).

To one skilled in the art, according to technical scheme described above and design, other various corresponding change and deformation can be made, and all these change and deformation all should belong within the protection domain of the utility model claim.
