Description

A kind of LED down

Technical field

The utility model relates to field of light fittings, particularly a kind of LED down.

Background technology

LED down is the product that application Novel LED illuminating light source improves exploitation on traditional Down lamp basis, contrast with traditional Down lamp and have the following advantages: be energy-conservation, low-carbon (LC), long-lived, colour rendering is good, fast response time, LED down is more welcome lighting apparatus during company or public place are fitted up in the market, because it compares with traditional light fixture is that power saving can reach more than 50%, and company and public place are the places needing long-time illumination, thus good thermal diffusivity is needed to ensure the service life of LED down, all airtight in the usual stack shell of LED down on existing market, the non-constant of thermal diffusivity, and the very twinkling eye that allows of some LED down light direct projections is very uncomfortable.

Utility model content

Therefore, for above-mentioned problem, the utility model provide a kind of rational in infrastructure, illumination is soft, the LED down of long service life, good heat dissipation effect.

For realizing above-mentioned technical problem, the solution that the utility model is taked is: a kind of LED down, comprise the stack shell of hollow, described stack shell bottom is provided with bottom, top end opening, described stack shell is provided with suspension frame, also comprise radiating seat, LED holder, LED lamp panel, soft light cover, bezel, locating ring, described radiating seat to be located in stack shell on bottom, described LED holder is located on the nozzle of stack shell removably, described LED lamp panel is fixedly arranged on LED holder, described LED holder outer ring is laid with some louvres, described stack shell outer surface is evenly equipped with radiating groove vertically, the described radiating groove vertically relative with louvre is equipped with and forms cross-ventilated first convection holes with louvre, described LED lamp panel is installed with locating ring, described soft light cover is located on locating ring, described stack shell is also provided with and covers in dismountable bezel above soft light cover.

Further improvement: on described radiating seat, vertical direction is provided with some heat radiation grooves, is equipped with the second convection holes in described heat radiation groove.

Further improvement: described bezel comprises the link removably connected with stack shell and the optically focused end covered in below soft light cover, and the internal perisporium of described optically focused end is equipped with reflective mirror.

Further improvement: the link of described stack shell upper end and bezel is respectively equipped with the thread segment matched, described bezel is located on stack shell with can screwing in back-out

By adopting preceding solution, the beneficial effects of the utility model are: by arranging soft light cover above LED lamp panel, the light of direct projection is made to seem very soft, can not dazzle, outer ring is laid with some louvres with LED holder, stack shell outer surface is evenly equipped with radiating groove vertically, cross-ventilated first convection holes is formed with the radiating groove that louvre is vertically relative is equipped with louvre, make lamp cylinder stack shell forms cross-ventilation, and in stack shell, be provided with the contact area that radiating seat increases stack shell and air, on radiating seat, vertical direction is provided with some heat radiation grooves simultaneously, the second convection holes is equipped with in heat radiation groove, make to form convection current again inside and outside radiating seat, radiating effect is very good, and reflective mirror is provided with on the internal perisporium of spotlight, by reflecting the light thus reinforcement intensity of illumination dispersed, solve the problem that LED down intensity of illumination is inadequate to a certain extent.
