Description

A kind of reflective surface LED illuminating lamp

Technical field

The present invention relates to the LED lighting technical field, especially relate to a kind of reflective surface LED illuminating lamp.

Technical background

Multiple advantages such as along with the development of led technology, the great power LED technology reaches its maturity, and it has the luminous flux height, the life-span is long, reliability is high, energy-conservation are the most potential light sources that substitutes existing lighting source.Existing LED light fixture generally be a plurality of power-type LEDs to be concentrated on the light fixture use, so the heat radiation of LED becomes a key factor that influences LED light fixture user mode and life-span.But existing LED light fixture generally adopts enclosed structure, and the heat of light source and driving power can not distribute timely and effectively, though the also radiator structure of special of the light fixture that has, complex structure usually, radiating effect is not good.The light ratio of LED spot light is more concentrated, if the light of LED is not dispersed in the outdoor lights, will be formed on the place that lamp is installed, and light is more concentrated, and brightness is bigger, and in the place away from lamp, brightness is less, does not reach the illumination needs.

In the existing high-power LED lamp, led light source generally is directly to be provided with towards ground, and the luminous efficiency of LED is increasingly high; The light of the emission of unit are is more and more stronger; Direct irradiation light is inhomogeneous, and bigger to the human eye stimulation, has a strong impact on the illuminating effect of LED light fixture; Watch for a long time, cause that easily visual fatigue even eyesight descend.And the reflectivity of reflecting material can reach 90% to 95% base to higher, and with reflecting design LED illuminating lamp, the light efficiency of sacrifice 5% to 10% reaches healthy illumination.

The utility model content

The utility model technical problem to be solved is to overcome the above-mentioned deficiency that existing LED light fixture exists, and a kind of simple in structure, good heat dissipation effect, illumination LED illuminating lamp more uniformly is provided.The utility model can be widely used in indoor and outdoor lighting.The utility model is realized through following technical scheme:

Technical problem to be solved by this invention is to overcome the above-mentioned deficiency that existing LED light fixture exists, and a kind of simple in structure, good heat dissipation effect, illumination reflective surface LED outdoor illumination more uniformly is provided.The present invention realizes through following technical scheme:

A kind of reflective surface LED illuminating lamp comprises LED light emitting module, circuit board, reflection shield, radiator, and said reflection shield middle body reflective surface is a convex surface, and the marginal portion of reflection shield is wherein one or more segmentation combinations on concave surface, convex surface, plane; LED is welded on the circuit board, and is positioned between said convex surface and circuit board, and light-emitting area is over against the middle convex surface of reflection shield.

Above-mentioned reflective surface LED illuminating lamp, the side of said LED luminous component is provided with the reflector that is used to reflect integral LED luminous component edge emergent ray.

Above-mentioned reflective surface LED illuminating lamp, the circuit board of the said LED of being welded with light emitting module sticks on the radiator with heat-conducting glue, and is screwed.

Above-mentioned reflective surface LED illuminating lamp, the said bonnet that connects light fixture in the behind of reflection shield, the below of reflection shield is provided with diffuser.

Above-mentioned reflective surface LED illuminating lamp, said reflection shield is formed by convex line, concave, straight segments combination back translation or rotation, or being formed by connecting after convex line, concave, rectilinear translation or the rotation.

Above-mentioned reflective surface LED illuminating lamp, the cross section of said convex surface and concave part is by circle, hyperbola, parabola or an oval part or segmentation combination.

Above-mentioned a kind of reflective surface LED illuminating lamp, circuit board, reflection shield scribbles reflecting material on the reflector.

Above-mentioned reflective surface LED illuminating lamp, said circuit board is connected with circuit power through lead, and power supply and circuit board are spaced apart.

The beneficial effect of the utility model is: the illuminator of the utility model (LED) is arranged on the below of the middle convex surface of said reflection shield with a determining deviation; With any way LED is placed on the convex surface below; Convex surface is dispersed the light of LED; Add concave surface, the plane reflection of reflecting of reflection shield both sides, make light in spatial dimension, reach demand.

Because several LED according to the invention are the reflective surface settings towards reflection shield; All light from led light source are reflections of this reflection shield of process earlier; Directive ground again, so illumination is more even, LED penetrates very strong light on very little area; This high light is easy to injure human eye, and the general light of the high-power LED lamp that the design has effectively avoided common employing led light source to be provided with towards ground compares rendezvous problem.The reflective surface of said reflection shield is a convex surface, and the outer surface that utilizes convex surface has increased the reflection of light angle as light reflection surface, makes ground under the constant situation of total luminous flux, and light evenly disperses, and irradiation range enlarges.The circuit board that is welded with LED among the design is equipped with radiator, and radiator exposes in air, forms good heat radiation and convection current.

Owing to have the place of light to scribble reflector layer on circuit board according to the invention and the light fixture, can better reflect away light.

Good optical of the present invention and heat dissipation design prolonged service life of LED light fixture, and fitting structure are simple, can save material, reduces cost.

The present invention avoids the light of high-brightness LED to inject human eye, reduces the surface brightness of light fixture; Variation more has the garden lamp of lamp stand in shape, also can make the light fixtures such as pendent lamp, Down lamp, bar shaped of regular geometry, can be widely used in the indoor and outdoor lighting.
