As preferably, described lampshade is arc, and has rough inner surface.

Light forms diffuse-reflectance at the inner surface of lampshade, can improve the uniform illumination degree of light fixture in this utility model, also has the effect increasing lighting angle.

As preferably, described base has the buckling groove coordinated with lampshade, and this buckling groove has the sidewall along lampshade top droop；Lampshade is had position-limiting action by this sidewall, it is prevented that lampshade is deviate from buckling groove, is beneficial to the clamping of lampshade.

As preferably, described flat part is provided with and adapts to the first slot that substrate inserts, and namely substrate inserts in the first described slot.

It is further preferred that two extensions are provided with the second slot, reflecting plate can be installed in this second slot, promote light and the uniformity.

As preferably, described bending part is provided with aduncate hook portion, is provided with installing plate between the hook portion of base both sides, and the both sides of this installing plate are provided with the Elastic buckle matched with hook portion.

Installing plate is provided with bolt, can be fixed on metope or ceiling, and the middle part of Elastic buckle is provided with snap fit tabs, and this snap fit tabs makes installing plate be clamped in base after entering hook portion, thus fixing LED lamp.

As preferably, described lamp holder includes the base plate in the end cap with lampshade laminating and inserted base；Described base bottom and base plate are respectively equipped with the buckle and draw-in groove that cooperate, fixing for lamp holder and base.

As preferably, the both sides of described base plate have the location-plate inserted below bending part, make lamp holder and base fit tightly；Gap between location-plate and base plate is used for threading, powers to the driving power supply in lamp holder.

As preferably, being inserted with sealing member between described location-plate and base plate, for sealed lamps, it is to avoid dust enters in light fixture.

This utility model simple in construction, it is simple to install, substrate adopts the mode of grafting to be fixed in base, and this base is also used as heat radiation, keeps the radiating effect that light fixture is good.
