Abstract

The utility model discloses a cut light formula anti -dazzle LED down lamp, including a lamp body, be provided with the LED light source in the lamp body, the front end of lamp body is provided with a light -emitting window, be provided with in the lamp body be used for with the LED light source with one of light -emitting window intercommunication leads to the chamber, is somebody's turn to do the plain noodles of cutting that the medial surface that leads to the chamber is mirror surface form, the front end that cuts the plain noodles extends to and flushes with the preceding terminal surface of light -emitting window. Because the utility model discloses the medial surface in well logical chamber has adopted the plain noodles of cutting of mirror surface form, and the order cuts the plain noodles and extends to and flush with the preceding terminal surface of light -emitting window, because the specular reflectance excluded of mirror surface is very low, the light that the LED light source sent is reflected away by a section plain noodles and throws light on, only there is the minute quantity not have light to be cut the plain noodles diffuse reflection even, consequently the luminance of light -emitting window department on can the effective control lamp body, very big weaken or even eliminated the luminance difference, can effectively weaken or even eliminate the glare, improve the comfort level that this LED down lamp used.

Description

A kind of section of light formula anti-glare LED down lamp

Technical field

This utility model is related to LED lamp field.

Background technology

The range of application of LED down widely, generally includes a lamp body and the LED light source being arranged in lamp body, lamp body Front end open up light-emitting window for being projected with the light of LED light source, because existing most of LED down are not in lamp body Wall is processed, and when using so in dim environment, the irradiation that the light-emitting window of lamp body is in LED light source light can be very bright Bright and form obvious luminance difference with the part outside light-emitting window on lamp body, thus easily produce dazzle, can be to the eye of user Mirror causes discomfort, and impact uses, and inwall can be made diffuse-reflectance face or go out to set up diffuse-reflectance in light-emitting window saturating by part LED down Divergence of beam to weaken glare effect, but so still cannot be eliminated and go out light on lamp body by tabula rasa or other diffuse-reflectance structures Oral area divides the situation that there is obvious luminance difference with other parts, does not fundamentally solve glare problem.

Utility model content

In order to solve the above problems, the purpose of this utility model is to provide one kind can effectively weaken or even eliminate dizzy Light, section light formula anti-glare LED down lamp of raising comfort.

This utility model employed technical scheme comprise that for solving its technical problem：

A kind of section of light formula anti-glare LED down lamp, including a lamp body, is provided with LED light source, the front end setting of lamp body in lamp body There is a light-emitting window, setting one cavity in lamp body, the light that LED light source sends can reach light-emitting window via this cavity, this cavity Medial surface is the optical cross section of a mirror-like, and the front end of described optical cross section is extended to and flushed with the front end face of light-emitting window.

Preferably, the fore-end of described optical cross section extends laterally and is formed around light-emitting window and the front end with light-emitting window Section light shirt rim of the ring-type that face flushes.

Preferably, described optical cross section is minute surface electroplating surface.

Preferably, described optical cross section is mirror face baking varnish face.

Preferably, the front portion of described lamp body is provided with one section of light shield, and lamp body and section light shield one are provided with least One buckle, another on be provided with the draw-in groove matching with described buckle, described buckle is connected in draw-in groove can will cut light shield Dismounting is fixed on lamp body, and described cavity is the inner chamber cutting light shield, and described optical cross section is the medial surface cutting light shield.

Preferably, described LED light source includes a substrate and is fixed on some LED lamp bead of substrate front end, and substrate sets It is equipped with the power adaptation element matching with described LED lamp bead.

Preferably, it is additionally provided with lens in described lamp body, described LED light source includes a substrate and is fixed on substrate Some LED lamp bead of front end, described substrate is fixed on lamp body, and described lens are located between LED lamp bead and light-emitting window simultaneously It is fixedly clamped on lamp body by lamp body and substrate.

The beneficial effects of the utility model are：Because the medial surface of cavity in this utility model employs section light of mirror-like Face, and make optical cross section extend to flushing with the front end face of light-emitting window, because the diffusing reflection rate of minute surface is very low, LED light source sends Light reflected away by optical cross section and be illuminated, only very small amount can therefore can by optical cross section diffuse-reflectance even without light Brightness at light-emitting window on enough effective control lamp bodies, greatly weakens or even eliminates luminance difference, can effectively weaken or even disappear Except dazzle, improve the comfort level of this LED down use.
