Abstract
The utility model discloses an improved structure of a LED lamp, which comprises a lamp body flat plate with transparent performance. A LED lamp source is arranged in the lamp body flat plate; the upper end surface of the lamp body flat plate is a non-emergent light surface, and the lower end surface thereof is an emergent light surface; the LED lamp source is annularly arranged in the lateral wall of a lamp body; and the emergent light surface is of a concave laminar staircase structure. The thickness of the laminar staircase structure of the emergent light surface descends layer by layer in a step manner from the emergent light surface to the non-emergent light surface. The non-emergent light surface of the lamp body flat plate is attached or coated with a reflecting layer. The outer side of the peripheral lateral wall of the lamp body flat plate is also attached or coated with a reflecting layer. A cover shell with a transparent or a frosted mirror surface is arranged on the outer cover of the lamp body flat plate. The emergent light surface is designed into a laminar staircase structure to lead out a light beam radiated in the lamp body flat plate by the LED light source; and in addition, by adopting the flat plate type laminar step structure, the lamp has the advantages of thinness, beautiful outer appearance, long service life and high energy utilization efficiency.
Description
Technical field
The utility model relates to the light fixture of a kind of light emitting diode (LED) light source.
Background technology
Along with the continuous progress of LED manufacturing technology, its light efficiency is constantly soaring, and the light efficiency of large power white light LED has reached 100lm/w up to now, and stable product light efficiency also has more than the 90lm/w.This light efficiency makes LED enter general lighting becomes possibility.One of the main work that LED is used for the popularization of general lighting must be prerequisite with the whole light efficiency that improves the LED illuminator exactly, and this relies on the Luminaire efficiency that improves LED or effective light utilization efficiency.
In addition, though led light source long service life, energy consumption are low, LED is a spot light, only emits beam to half space, and the result causes two aspect adverse effects: the one, and the light that light source sends shines the illuminance of ground skewness, and is middle dark around bright; The 2nd, light source has strong dazzle, and euphorosia is very poor.So just need to see through illuminance uniformity, the brightness uniformity of secondary optics design raising LED light fixture and eliminate dazzle, improve euphorosia, make it to be applicable to lighting of home.
As publication number is the Chinese invention patent of the LED lamp of a CN200810047449.8 reflecting condensation, has just adopted the secondary optics design, and it comprises LED, Baltimore groove, bullet and packaging body; Sidewall at Baltimore groove is provided with LED, is provided with bullet in the bottom of Baltimore groove, is provided with packaging body at the top of Baltimore groove.Though this structure has also improved the illuminance uniformity of LED light fixture to a certain extent, practical effect is not ideal enough.
The utility model content
Technical problem to be solved in the utility model just provides a kind of LED lamp improved structure, and its illuminance uniformity, brightness uniformity are good, effectively eliminate dazzle, have improved euphorosia simultaneously.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of LED lamp improved structure, comprise lamp body flat plate with light transmission, be provided with led light source in the lamp body flat plate, it is characterized in that: described lamp body flat plate upper surface is non-exiting surface, the lower surface is an exiting surface, and described led light source is located in the lamp body sidewall, and described exiting surface is the stratiform hierarchic structure of indent formula.
As preferably, described lamp body flat plate is lucite or engineering plastics.Be convenient to light generation scattering.
As improvement, the stratiform hierarchic structure of described exiting surface is the ladder that thickness successively descends from exiting surface to non-exiting surface direction.Perhaps the stratiform hierarchic structure of described exiting surface is the ladder that thickness successively increases from exiting surface to non-exiting surface direction.Be convenient to light generation scattering like this, make distribution of light even.
As preferably, the non-exiting surface of described lamp body flat plate is sticked or plates and establish a reflector layer.The outside of sidewall all around of described lamp body flat plate also is sticked or plates and establish a reflector layer.Reflector layer is main to be to play reflex, makes all light improve the utilization rate of light from the exiting surface outgoing, does not have light to escape.Simultaneously can make the light generation scattering that shines on the reflector layer, make distribution of light even.
Further improve, described lamp body flat plate is covered with the case of the transparent or frosted of minute surface.The protection lamp body flat plate.
In addition, described lamp body flat plate is circle or rectangular flat.
The utility model is owing to adopted technique scheme, all led light sources to be sidelong around the lamp body flat plate in the sidewall, and submergence, can avoid LED luminescence chip brightness height, easily cause the shortcoming of dazzle, make and far see light fixture, do not have the granular sensation of LED fully, light is soft comfortable.Exiting surface is designed to from level to level stratiform hierarchic structure, and integral body presents recess, is convenient to draw led light source and is radiated at light in the lamp body flat plate, and flat stratiform hierarchic structure that light fixture can be accomplished is very thin, good looking appearance, life-span while is long, the energy utilization efficiency height.
