Abstract

The utility model discloses an LED (light-emitting diode) lamp which consists of an LED fixing ring, a plurality of LED bulbs and transparent transmitting media, wherein the LED bulbs are fixed on the LED fixing ring, illuminate towards the periphery and are positioned in the transparent transmitting media; inclined planes are formed at the peripheries of the transparent transmitting media and form reflectors; the inner included angle Alpha between each reflector and the horizontal direction is greater than or equal to 10 DEG and less than or equal to 45 DEG; as light emitted from LEDs is directive, the LED bulbs illuminate the periphery radially, and the light is transmitted in the transparent transmitting media and reflected downwards when encountering the inclined planes at the peripheries of the transparent transmitting media, namely the reflectors; the LED lamp avoids glare of the high-power LEDs and allows the light emitted from the high-power LEDs to be uniform and soft, so that the high-power LEDs can be used for indoor illumination, and the application scope of the high-power LEDs is expanded.

Description

The LED light fixture

Technical field

The utility model relates to a kind of lighting, particularly a kind of LED light fixture.

Background technology

The light that great power LED sends has dazzle property, so great power LED is not suitable for room lighting and uses, and has limited its range of application.

Summary of the invention

The purpose of the utility model is will solve great power LED not to be suitable for the problem that room lighting uses, and a kind of LED light fixture that makes great power LED can be used for room lighting is provided.

The utility model is made up of LED retainer ring, LED bulb and transparent conductive medium; A plurality of LED bulbs are fixed on the LED retainer ring; The direction of illumination of every LED bulb is towards periphery, and every LED bulb is arranged in the transparent conductive medium, and the periphery of transparent conductive medium has the inclined-plane; This inclined-plane constitutes reflective mirror, and the interior angle of this reflective mirror and horizontal direction is: 10 °≤α≤45 °.

Described LED retainer ring is a metal material, like aluminium or copper, helps the heat radiation of LED bulb.

Said transparent conductive medium is poly (methyl methacrylate) plate or transparent plastic sheet.

The course of work of the utility model is:

Because the light that LED sends has directionality, a plurality of LED bulbs are radial and conduct in the transparent conductive medium to irradiation all around, after the inclined-plane that runs into transparent conductive medium periphery is reflective mirror, and reflection downwards.

The beneficial effect of the utility model: the utility model has overcome great power LED dazzle property, and the light that great power LED is finally sent is evenly soft, and then makes great power LED can be used for room lighting, has enlarged the scope of application of great power LED.
