Above-mentioned a kind of Reflecting surface LED illuminating lamp, circuit board, reflection shield scribbles reflecting material.
Above-mentioned a kind of reflective surface LED outdoor illumination, described circuit board is connected with circuit power by wire, and power supply and circuit board are spaced apart.
Above-mentioned a kind of Reflecting surface LED illuminating lamp, described LED light module can fill one, also can install many.
The invention has the beneficial effects as follows: illuminator LED of the present invention is arranged on described reflection shield right opposite with a determining deviation, in any way LED is placed on convex surface right opposite, and the light of LED is dispersed by convex surface, makes light reach demand in spatial dimension.
LED penetrates very strong light on very little area, and this high light is easy to injure human eye, especially when vertically penetrating; Because several LED of the present invention are arranged towards the reflective surface of reflection shield, all light from LED light source is the reflection first passing through this reflection shield, then is shot out, and therefore illumination is more even, and avoids vertical light direct projection human eye.
In the design, the reflective surface of reflection shield is convex surface, utilizes the outer surface of convex surface as light reflection surface, adds the reflection angle of light, with making when total luminous flux is constant, light is dispersed, and irradiation range expands, and efficiently solves the problem that LED light source light compares gathering.
The circuit board being welded with LED in the design is equipped with radiator, and radiator is in atmosphere exposed, forms good heat radiation and convection current.
Because circuit board of the present invention, the reflective place being covered with light reflection scribble reflector layer, light better can be reflected away.
The optics that the present invention is good and heat dissipation design, extend the service life of LED lamp, and fitting structure is simple.
The present invention is more diversified in shape, can make the garden lamp with lamp stand, also can make the light fixtures such as the pendent lamp of regular geometry, Down lamp, strip light, can be widely used in indoor and outdoor lighting.
