Abstract
The utility model provides an LED lamp with a dimming function. The LED lamp comprises an LED bulb consisting of an LED lamp bead and a lamp bead installation circuit board and a shell, a power supply, a dimming control circuit and a power supply connector. The bulb is electrically connected to the power supply and the AC output end of the dimming control circuit through wires, and the power supply connector is connected to the power supply and the electric supply input end of the dimming control circuit. The LED lamp provided by the utility model has a simple structure, can be applied to illumination and decoration lamps with various forms, and realizes continuous adjustment to luminance and brings convenience for operation. Because the bulb and the control circuit are reasonably separately arranged, the LED lamp with the dimming function effectively prevents components from being aged, is longer in the service life, and is greatly enhanced in the safety and reliability.
Description
Technical field
The utility model relates to a kind of LED lamp, the LED lamp that particularly can regulate brightness.
Background technology
With the LED lamp as the illuminating lamp of light emitting source have energy-conservation, without advantages such as stroboscopics, entered since 21 century, be widely used, in lighting of home, the LED lamp replaces fluorescent lamp, incandescent lamp to use usually.But owing to have multiple photochromic, brightness wide region adjusting, and luminous efficiency is high, and security is good, as the light source of desk lamp, decorative lamp, is subject to more and more people's favor.
The LED lamp adopts the light-emitting diode of low-voltage, little current drives as light emitting source, when the access civil power uses, need carry out step-down, current limliting, and therefore, power control structure is indispensable.LED lamp with brightness control function must have the brightness adjustment control structure simultaneously.Be the needs of compact conformation, power control circuit and adjusting control circuit are combined into power supply and light modulating device.Common design is that LED lamp pearl is directly installed on the control device circuit board, and circuit board and the compact placement of power board of LED lamp pearl perhaps will be installed, and encapsulates again, forms complete bulb and uses.The bulb of this structure, during as the light source of desk lamp etc., the light modulation action need carries out on the connecting portion surface of bulb and power supply, brings inconvenience for the design of light fixture, also easily causes electric shock accidents when the user operates; Simultaneously, because heat dispersion is poor, have safety problem, the safety coefficient of this bulb is low.Power control circuit or adjusting control circuit break down, and need open bulb shell when checking, reliability is low, therefore, need to the setting of power supply and light adjusting and controlling device be made improvements.
Summary of the invention
Use the LED lamp to be the reliability of security and the maintenance of the lighting of light source for improving, the utility model provides a kind of LED lamp that light adjusting and controlling device is set separately that has, and it is simple in structure, carries out the light modulation operation and is very easy to, safety coefficient is high, can safeguard easily.
The technical solution of the utility model is that a kind of light-adjustable LED lamp comprises LED lamp pearl, lamp pearl mounting circuit boards, power supply and adjusting control circuit plate and power connection, it is characterized in that, the bead weld of LED lamp is connected on the lamp pearl mounting circuit boards, is installed in the bulb shell, consists of bulb; Power supply and adjusting control circuit plate are installed in the control box, have mains electricity input end and dc output end, and the mains electricity input end is electrically connected with power connection, and dc output end is electrically connected with lamp pearl mounting circuit boards power interface.
Power supply and adjusting control circuit plate are arranged separately in the control box, the wire that can select suitable length according to style and the purposes of light fixture, be electrically connected with lamp pearl mounting circuit boards, therefore, power supply and brightness adjustment control box can be placed on the position of being convenient to people's operation by designing requirement, carry out switch and light modulation operation, easy to use.Simultaneously, LED lamp pearl and power supply and adjusting control circuit plate are installed separately, and prevent that the heat of generation when LED pearl lamp uses from the impact of control circuit electronic devices and components, making the control circuit dimming effect more stable.
In the use, break down such as power control circuit or adjusting control circuit, only need opening power and brightness adjustment control box to repair or replace components and parts, reliability is high.
With the LED lamp of the utility model structure, the LED bulb that encapsulates with existing power supply circuit board and LED lamp pearl, through the experiment contrast, be greatly improved its service life, and the brightness regulation scope of LED lamp can from 1% to 99%, and dimming effect is more stable.
Description of drawings
Fig. 1 is the utility model STRUCTURE DECOMPOSITION figure.
Fig. 2 is the utility model embodiment cutaway view.
The specific embodiment
1,2 a kind of embodiment of the present utility model is described with reference to the accompanying drawings.
A kind of light-adjustable LED lamp comprises LED bulb 1, power supply and brightness adjustment control box 2, power connection 3 and wire.The LED bulb is comprised of lamp pearl 4, lamp pearl mounting circuit boards 5, bulb shell 6.Power supply and brightness adjustment control box 2 interior installation power supply and adjusting control circuit plates 7, circuit board has mains electricity input end 8 and dc output end 9, is electrically connected with power connection 3 and lamp pearl mounting circuit boards 5 respectively.During use, power connection is accessed civil power, electric main offers the lamp pearl after power supply and light adjusting circuit carry out step-down, rectification, make the lamp pearl luminous, namely realizes illumination or the effect of decorating.The knob 10 that rotary power source and adjusting control circuit plate 7 connect, the size of current of regulating input lamp pearl just can make the brightness of lamp pearl change, and realizes the function of light modulation.
LED lamp of the present utility model can be applicable to the lighting lamp of household, the shot-light of folder lamp, floor lamp and decoration function, chain lamp etc., lighting lamp as shown in Figure 2.The utility model adopts power supply and light adjusting circuit and LED bulb to divide and is arranged, the mode of utilizing wire to be electrically connected can according to the characteristics of different lamps, be selected the wire of different length, with power supply and the setting of brightness adjustment control box in position, make things convenient for the user to operate.And the heat that sends when effectively preventing owing to the use of LED lamp pearl affects the stable of light adjusting circuit board component, and brightness regulation is more reliable.
