Description

A kind of double light source led downlights with focusing structure

Technical field

The utility model relates to a kind of LED lamps, espespecially with the LED downlight of focusing structure.

Background technique

With the increasingly raising of the development living standards of the people of society, people are when commercial and house fitting-up to illumination It is required that it is higher and higher, the downlight for regional area illumination is not only installed according to different daily life demands, also to install makes The ambient lighting lamps and lanterns that entire room illuminates.To divide to meet this demand lamps and lanterns of two class difference purposes when finishing It Da Kong not install and be routed, not only waste wire rod with manually, also ceiling can be made to seem disorderly and unsystematic.

In order to solve this problem, this now with a kind of adjustable focus downlight (number of patent application CN201420201963) Lamps and lanterns include front shroud, sliding part, location rubber ring and plano-convex lens, and front shroud and sliding part are in the hollow structure of both ends open respectively, Location rubber ring is set in the location rubber ring slot that sliding part outer wall opens up, and sliding part is installed in the inside of front shroud and can be along front shroud Axial direction is mobile, and location rubber ring is in contact with the inner wall of front shroud, so that sliding part and front shroud is rubbed and positions, plano-convex lens are fixed on On the inner wall of sliding part.It, can be with according to the needs of different lighting environments when lamps and lanterns focusing structure and light source assembly are used cooperatively The distance between plano-convex lens and light source assembly are adjusted, to achieve the purpose that the size and brightness of illumination of adjustment projection hot spot.But It is that lamps and lanterns this in actual use can have the following problems: although the lamps and lanterns can reach adjustment projection hot spot by focusing Size and brightness of illumination, so that lamps and lanterns is met the needs of local lighting function or ambient lighting function, but this kind of lamps and lanterns are logical Often be mounted on very high position from the ground, be installed back focusing be it is highly difficult, be unable to satisfy user partial illumination functions and Ambient lighting function is converted immediately, and let alone local lighting function and ambient lighting function be simultaneously and the demand deposited.

Summary of the invention

The purpose of this utility model is that releasing a kind of novel LED downlight with focusing structure, solve previous Adjustable focus downlight has a single function, and the local lighting function and ambient lighting function of lamps and lanterns cannot be converted immediately and cannot while and be deposited The problem of.

Purpose of the utility model is realized as follows: lamp mask is a perforative annular peviform structure, annular LED hair Optical assembly is fixed on the ring-shaped step bottom surface of lamp mask.

The utility model can also add a lampshade before annular LED luminescence component and lamp mask, and lampshade and lamp mask connect It is connected together.

The lampshade of the utility model can be linked together with lamp mask by helicitic texture.

The annular LED luminescence component of the utility model is aluminum substrate structure, is welded with a circle low-power LED chip above.

For the utility model since lamp mask is a perforative annular peviform structure, an annular LED luminescence component is fixed on lamp On the ring-shaped step bottom surface of mask, the luminescence component that two kinds of different purposes work independently is set on a lamps and lanterns, keeps lamps and lanterns same When have the function of local lighting and ambient lighting function, can individually be lighted according to living needs or be lighted simultaneously.

A translucent lampshade is increased outside the LED luminescence component for playing ambient lighting function, not only solves use When LED lamp panel be also easy to be touched damage, solve and caused to the eyes of user due also to semi-transparent configuration also mitigates LED lamplight The problem of dazzle.
