The LED lamp can be used for lighting continuously and subjected to brightness adjustment in multiple brightness levels so that the lighting brightness requirements of the lamp can be met in different lighting environments.
Description
Affiliated technical field
The present invention relates to the electric lighting field, especially, is a kind of LED lighting that can regulate brightness of illumination.
Background technology
LED is as a kind of energy-saving illumination equipment; The light emitting diode of its core luminous component for constituting by PN junction, under electroluminescent effect, it has advantages such as brightness height, energy consumption are little; Therefore be widely used in various illuminations place in recent years, and it is constructed and pattern is also enriching rapidly.
In order to satisfy the lamp lighting brightness demand under the different light environment; Desirable lighting should be regulated brightness in a big way, normally, and when ordinary lamp and lantern is regulated brightness; General input voltage or the input current of changing can be realized the brightness regulation in the successive range; Yet, for the LED lamp, because the electroluminescence characters of light emitting diode; When voltage (electric current) is excessive or too small; To make it luminous very unstable, therefore, present LED illumination is under stable case; Its brightness regulation can only be limited to a small range, is difficult to satisfy the needs of brightness of illumination adjusting on a large scale.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of many brightness degrees LED lamp, this LED lamp can realize in a plurality of brightness degrees that brightness of illumination is regulated continuously, to satisfy the lamp lighting brightness demand under the different light environment.
The technical solution adopted for the present invention to solve the technical problems is: this many brightness degree LED lamp comprises arraying bread board; Be uniformly distributed with light emitting diode on this arraying bread board; Said arraying bread board rear is a matrix, is provided with input in the matrix and is electrically connected the led controller that power line, output are electrically connected said light emitting diode;
Said arraying bread board the place ahead is provided with the tube cover, and laterally arrange in this cover two or two above LCD panels, each said LCD panel are arranged at the independent respectively control of liquid-crystal controller in the said matrix.
As preferably, said liquid-crystal controller has many to output pin arranged side by side, and said many logarithms to pin equate with the quantity of said LCD panel; Each can export high level or low level independently to output pin; And each is electrically connected the said LCD panel of a slice respectively to pin, and when pin output high level, its pairing LCD panel is muddy look; During output low level, its pairing LCD panel is transparence.
As preferably, leave the space between each LCD panel in the said tube cover, to reduce interference phenomenon.
As preferably, said tube cover front end also is provided with the outside transparent sphere protective cover that of encircleing.
As preferably, said sphere protective cover is concavees lens, to play the effect of dispersing light source.
The invention has the advantages that: this many brightness degree LED lamp is when illumination; Each said LCD panel is represented a brightness degree, and the LCD panel quantity of being connected by high level is many more, and then brightness degree is low more; Promptly dark more; In each brightness degree,, can realize the continuous adjusting of the brightness of illumination in this brightness degree through the input voltage or the electric current of led controller adjusting light emitting diode; So this LED lamp can satisfy the lamp lighting brightness demand under the different light environment at the enterprising step joint of a plurality of brightness degrees brightness of illumination in a big way.
Description of drawings
Fig. 1 is the structural representation of an embodiment of this many brightness degree LED lamp.
