The reflecting LED lamp disclosed in the invention is not only capable of producing a gentle and glareproof light illumination effect, but also capable of obtaining arbitrary and precise three-dimensional reflecting cavities for further increasing the reflection efficiency of the light and improving uniform distribution of the light, and has the advantages of good heat dissipation effect, simple production process and lower cost.
Description
Technical field
The present invention relates to lighting field, saying of body more relates to a kind of structure of reflecting LED illuminating lamp.
Background technology
LED is as lighting source, energy-saving and environmental protection, advantage are efficiently arranged, but brightness height because its volume is little, its optically focused characteristic can produce the serious glare problem when making direct projection, light is not soft and allow the people feel very uncomfortable, if the LED spot light is converted to surface source luminescence, can effectively solve glare problem, the present a kind of indoor reflection formula LED illuminating lamp that occurs, be to adopt on the reflection cavity wall of lamp, to paste one deck reflective membrane, utilize reflective membrane that light is reflected away, can solve glare problem.But because reflective membrane need match with the shape of reflection cavity wall, therefore, to the reflection chamber of arbitrary structures and shape, reflective membrane can't accurately be accomplished the stickup of fitting fully.Therefore its use is subjected to certain restriction.Again because the shape of the reflection chamber of indoor reflection formula LED illuminating lamp, size and and LED between relative position and angle reflection efficiency, light are evenly distributed with very big influence, so the LED illuminating lamp also needs a rational catoptric arrangement and reflection chamber.The reflection cavity of conventional reflective LED illuminating lamp generally is reflective plate stamping flanging, and generally open, like this, not only can't accurately obtain required reflector shape, more be difficult to realize for three-dimensional sphere, ellipsoid etc., and for high-power LED illuminating lamp, this reflection cavity separates the form that designs with the heat dissipation metal shell, and its radiating effect is not good yet.
Summary of the invention
The present invention is directed to above-mentioned technical problem, a kind of reflecting LED illuminating lamp is provided, not only can produce the light effect that of soft, free from glare, and can obtain arbitrarily, the reflection chamber of accurate 3D shape, the reflection efficiency and the light that further improve lamp evenly distribute, and radiating effect is good, and production technology is simple, and cost is lower.
For achieving the above object, the technical solution used in the present invention is as follows:
A kind of reflecting LED illuminating lamp, comprise shell and installation led light source in the enclosure, described shell is to adopt die casting, injection moulding or the technology manufacturing of extruding forms, on the internal chamber wall of described shell, scribble one deck diffuse reflection coating, outer setting at described shell has radiator structure, and led light source is installed in the edge, the end near the shell inner cavity wall, when shining under the LED illuminating lamp court, the optical axis of led light source up, this optical axis is positioned at 45 ° of scopes of vertical direction left and right sides deflection.
The edge is provided with the mounting base that is used for placing led light source at the bottom of the described shell.
Described shell inner cavity wall is level and smooth secondary, three times or curved-surface structure repeatedly.
Described shell inner cavity wall is sphere shape, ellipsoid face structure.
Described shell inner cavity wall is plane, plane splicing construction.
When LED illuminating lamp when being high-power, described shell is a metal, and described radiator structure is arranged on the outer shell outer wall, is made into integration with shell.
When the LED illuminating lamp was small-power, described shell was plastics, and described radiator structure is arranged on the mounting base on edge at the bottom of the described shell.
The beneficial effect that technical solution of the present invention is brought:
Reflecting LED illuminating lamp disclosed in this invention adopts injection moulding, die casting, expressing technique, processes by mould and obtains 3D shape that the shell inner cavity wall needs arbitrarily, accurate, to satisfy the requirement of illuminating lamp to light utilization and uniformity distribution.And, being formed with the reflective cavity of reflecting effect by on the internal chamber wall of shell, spraying reflective coating, the way of this sprayed coating can generally be suitable for, and is not subjected to the constraint and the restriction of lamp reflection chamber structure and shape, and with low cost, operates simpler.Simultaneously, select to have the diffuse reflection coating of high reflectance, can further improve the reflection efficiency of light.When LED illuminating lamp when being high-power, shell adopts metal to make, and radiator structure is formed by outer shell outer wall, with shell be one; When the LED illuminating lamp is small-power, shell adopts plastics to make, and radiator structure is the mounting base that is used for installing led light source that is arranged on edge at the bottom of the shell, like this, under high-power situation, shell is the reflecting LED illuminating lamp that a kind of heat radiation combines with reflective cavity not only by the outer wall heat radiation but also by the inwall reflection ray.Led light source is installed in edge, the end near the shell inner cavity wall, when the LED illuminating lamp towards under when shining, the optical axis of led light source up, this optical axis is positioned at 45 ° of scopes of vertical direction left and right sides deflection.In this scope, have the light more than 50% to send again by a diffuse reflection at least in the light that led light source sends, and when human eye when light fixture is watched, can't see LED, thereby can effectively alleviate glare problem.
