2, the luminous intensity because of the LED spot light is big, be easy to generate dazzle (so-called dazzle, be meant in the visual field owing to be not suitable for Luminance Distribution, or on space/time, there is an extreme brightness contrast, so that cause that vision is uncomfortable and reduce the visual condition of object visibility), people generally can add match grinding and sand flat glass sheet and handled before light fixture, though eliminated dazzle like this, the light extraction efficiency of LED light fixture also can be a greater impact.
The utility model content
Technical problem to be solved in the utility model is the deficiency that overcomes the above-mentioned background technology, and a kind of arc bell-type LED light fixture is provided, and that this LED light fixture should have is simple in structure, light is soft, light emission rate is high, good looking appearance, the characteristics being convenient to safeguard.
The utility model can be achieved through the following technical solutions:
Arc bell-type LED light fixture, comprise led light source, the power module that operating voltage is provided that emits beam, the radiator that distributes heat that led light source produces, regulate the light fixture rising angle reflector, light fixture is positioned at installing rack on the ceiling; Power module is installed in the position of center line of radiator, and led light source is installed in the radiator bottom, and the top of reflector is fixed on the led light source, and the outer wall of the lower openings of reflector is being fixed described installing rack; It is characterized in that: described LED light fixture also comprises an arc cover that is fixed on described reflector top, is positioned at led light source below, and all led chips that the reverse cover cap of this arc cover led light source are with the light diffuse reflection.
Described arc cover is fixed in the described reflector by helicitic texture; The top of reflector inwall is shaped on a circle internal thread, and the top of arc cover outer wall is shaped on the external screw thread that matches with aforementioned internal thread of circle the arc cover is fixed on below the led light source.
Described arc cover is fixed in the described reflector by buckle structure; The top of reflector inwall is shaped on several inwardly outstanding and along the circumferential direction uniform boss, and the top of arc cover outer wall is shaped on the groove of a circle and aforementioned boss tabling the arc cover is fixed on the led light source below.
Described arc cover is bonded in the top of described reflector inwall by glue.
The beneficial effects of the utility model are: the utility model is on the basis of conventional LED light fixture, increase the light that led light source is sent and carried out irreflexive arc cover, by control to diffuse reflection degree and light emission rate, make light softer, when light emission rate is high, reach the requirement of anti-dazzle, also avoided the aberration of the preceding hot spot of lamp to change and the light and shade variation, visually more attractive in appearance; In addition, the utility model is simple in structure, and profile is better appearance also.

The specific embodiment
Below in conjunction with Figure of description, the utility model is described in further detail.
Embodiment 1:
As shown in Figure 1, a kind of arc bell-type LED light fixture described in the utility model comprises power module 1, radiator 2, led light source 3, reflector 4 and installing rack 7; Described led light source is installed in the bottom of radiator, fix by screw thread, screw, the mode that presses between the two, during installation by the heat radiation requirement of led light source different capacity, the radiator of configuration different volumes, radiator can be made by different Heat Conduction Material, also can be active heat sink, heat pipe of electronic type etc.; Power module is used for providing operating voltage and constant current to led light source, the position of center line that this power module is installed in radiator is beneficial to heat radiation, and (radiator is a hollow structure, also power module can be installed in radiator top or external, specifically determine) according to actual conditions; Reflector can adopt metal or other materials to make, the top of reflector is fixed on the led light source or is fixed on the radiator bottom, can fix by modes such as screw thread, screws between reflector and the led light source (or radiator), the outer wall of the lower openings of reflector is being fixed described installing rack (can fix by screw or the mode that presses), this installing rack is used for light fixture is fixed on ceiling, during use, pull open stand spring 6, light fixture is put into the installing hole of ceiling, and the releases clamp spring can be fixed light fixture then.Said structure is all similar with conventional light fixture.
