Abstract

The invention provides a multi-brightness-level LED (light-emitting diode) lamp which comprises an array faceplate. The array faceplate is evenly provided with LEDs, a substrate is arranged behind the array faceplate, an input end electrically connected with a power wire and an output end electrically connected with an LED controller of the LEDs are arranged in the substrate, a barrel cover is arranged in front of the array faceplate, two or more than tow liquid crystal sheets arranged in parallel in the barrel cover, and each liquid crystal sheet is respectively and independently controlled by a liquid crystal controller arranged in the substrate. 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

Many brightness degrees LED lamp

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.

Fig. 2 is the electrical structure diagram of Fig. 1 embodiment.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the present invention is further specified:

Fig. 1, embodiment illustrated in fig. 2 in; This many brightness degree LED lamp comprises arraying bread board 2; Be uniformly distributed with light emitting diode 3 on this arraying bread board 2; Said arraying bread board 2 rears are matrix 1, are provided with input in the matrix and are electrically connected the led controller 30 that power line, output are electrically connected said light emitting diode 3;

Wherein, power line is drawn in said matrix 1 through a power line protection handle 5.

Said arraying bread board 2 the place aheads are provided with tube cover 7, and the multi-disc LCD panel 4 that laterally arranges in this cover 7, each said LCD panel 4 are arranged at the independent respectively control of liquid-crystal controller 40 in the said matrix 1; This liquid-crystal controller 40 is also by AC power 201 power supplies.

Above-mentioned many brightness degrees LED lamp, said liquid-crystal controller 40 has many to output pin arranged side by side, and said many logarithms to pin equate with the quantity of said LCD panel 4; Each can export high level or low level independently to output pin; And each is electrically connected the said LCD panel 4 of a slice respectively to pin, and when pin output high level, its pairing LCD panel 4 is muddy look; During output low level, its pairing LCD panel 4 is transparence.

Above-mentioned many brightness degrees LED lamp leaves the space between each LCD panel 4 in the said tube cover 7, to reduce interference phenomenon.

Above-mentioned many brightness degrees LED lamp, said tube cover 7 front ends also are provided with the outside transparent sphere protective cover 6 that of encircleing, and said sphere protective cover 6 is concavees lens, plays the effect of dispersing light source simultaneously.

Above-mentioned many brightness degrees LED lamp is when illumination; Brightness degree of each said LCD panel 4 expression, LCD panel 4 quantity of being connected by high level are 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 30 adjusting light emitting diodes 3; 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.

The above is merely preferred embodiment of the present invention, and is in order to restriction the present invention, not all within spirit of the present invention and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
