Technical field

The utility model relates to lighting field, relates in particular to a kind of LED lighting.

Background technology

Existing LED bulb lamp adopts led light source to send light and shines directly into that logical again globe holder scatters out on the globe holder, because the led light source lighting angle is at 120 degree, the angle of scattering that adds globe holder is 20 degree, and the lighting angle of final light fixture is all less than 150 degree; There is a big difference at the luminous angle of 300 degree of more traditional incandescent lamp, is restricted thereby annular in many instances prism LED bulb lamp substitutes the incandescent lamp of high energy consumption.

The utility model content

The utility model aims to provide a kind of annular prism LED bulb lamp, increases the lamp lighting angle, the restriction that the incandescent lamp of the alternative high energy consumption of solution LED bulb lamp is subjected to, energy savings.

For achieving the above object, the utility model is realized by the following technical solutions:

The disclosed annular prism LED bulb lamp of the utility model comprises the lamp body, lampshade, the first annular LED light source module, the annular triangle corner angle composite light guiding body that contain driving power assembly, lamp holder, radiator; Described lampshade is spherical, be installed in the lamp body front end and constitute a closed cavity, the described first annular LED light source module, annular triangle corner angle composite light guiding body are positioned at above-mentioned closed cavity and are installed in the front end face of lamp body, the first annular LED light source module surrounds annular triangle corner angle composite light guiding body, and the outer surface of described annular triangle corner angle composite light guiding body comprises the incomplete back taper face of one deck at least.

Preferably, described back taper face be positioned at the first annular LED light source module directly over.

Further, be provided with the second annular LED light source module in the described annular triangle corner angle composite light guiding body, the described second annular LED light source module is installed in the front end face of lamp body.

Further, the inwall of described annular triangle corner angle composite light guiding body is provided with reflector.

Further, described reflector inboard is provided with and comprises a sphere and a paraboloidal reflecting surface, and this reflecting surface is coated with reflector layer, and its reflectivity is 10% to 90%.

Preferably, the described first annular LED light source module is a multilayer LED light source ring, and the led light source quantity of interior side ring is not more than the led light source quantity of outer ring.

Preferably, the material of described annular triangular prism composite light guiding body can be transparent optical plastic cement or glass.

Further, the described first annular LED light source module is provided with the thermal conductivity aluminum matrix plate.

Further, the described second annular LED light source module is provided with the thermal conductivity aluminum matrix plate.

The utility model has increased the light angle of light fixture, makes circumference 360 degree of light fixture can both reach close illuminating effect, and energy is replace incandescent fully, and energy savings has good economic benefit.
