Abstract

The utility model relates to a LED stepless light-change lamp, which comprises a stabilized voltage supply, a controller and LED lamps; wherein, the stabilized voltage supply is composed of a power input end, a stabilized voltage supply board and a power output end; the controller comprises a control circuit board provided with a singlechip, a control button and two LED lamps; the power output end of the stabilized voltage supply is electrically connected with the control circuit board, the control button and the LED lamps; capacitors (C5, C6) and a resistor (R2) are connected between the singlechip and the input end; resistors (R3, R4) and triodes (Q2, Q3) are connected between the singlechip and the LED lamps; the single chip is connected with the control button (S1); the two LED lamps are also connected with resistors (R5, R6). The LED stepless light-changing lamp can use only one button to respectively control the on-off of the two LED lamps and the brightness of the two LED lamps, so the used elements are less, and the cost is low. The light of the LED lamps is almost natural, so more energy can be saved. The alternating current/direct current LED stepless light-change lamp can realize the smooth regulation of brightness and can be conveniently operated and controlled.

Description

LED stepless dimming lamp

Technical field

The utility model relates to technical field of lamps, particularly a kind of LED stepless dimming lamp that can carry out the smooth adjustment lamplight brightness.

Background technology

At present; on factory, school or the vehicles, usually need to use the light fixture of directional lighting; for example automobile bodies intraoral illumination, factory's operating desk illumination or school, home-use desk lamp etc.; typically use the electricity-saving lamp or the incandescent lamp that add upper lamp shade; the lamplight brightness of this class lamp is fixed, and be not easy to control, and power is relatively large; power consumption is more, sometimes because the effect of illumination is crossed by force or more secretly can be had influence on to light.

The utility model content

At the deficiency of above existing lighting, the purpose of this utility model provide a kind ofly be convenient to regulate lamplight brightness, power consumption is littler, cost is lower, and can connect the LED stepless dimming lamp of AC power or DC power supply.

The purpose of this utility model is achieved by the following technical solution:

LED stepless dimming lamp, comprise stabilized voltage power supply, controller and LED lamp, described stabilized voltage power supply is made up of power input, stabilized voltage power supply plate and power output end, described controller comprises control circuit board, control button and the LED lamp that is provided with single-chip microcomputer, and the power output end of stabilized voltage power supply forms with control circuit board, control button and LED lamp and is electrically connected.

As optimal technical scheme of the present utility model, be connected with a control button and two LED lamps on the described control circuit board.

As optimal technical scheme of the present utility model, described control circuit board comprises power input and the LED lamp that is connected with single-chip microcomputer, between single-chip microcomputer and power input, be connected with capacitor C 5, C6 and resistance R 2, between single-chip microcomputer and LED lamp, be connected with resistance R 3, R4 and triode Q2, Q3, single-chip microcomputer is connected with control button S1, and two LED lamps also are connected with resistance R 5, R6.

As optimal technical scheme of the present utility model, described controller also comprises shell, and control circuit board is installed in the enclosure, and control button and LED lamp are exposed to outside the shell.

The beneficial effects of the utility model are: adopt a control button can control the switch of two LED lamps respectively, can also control simultaneously the brightness of two LED lamps, the element that the utility model uses is less, cost is lower, the light of LED lamp is near natural daylight, and is more energy-conservation, and can realize the smooth adjustment lamplight brightness, AC/DC is dual-purpose, and operation control is very convenient.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:

Fig. 1 is an external structure view of the present utility model;

Fig. 2 is the circuit diagram of the utility model control board;

Embodiment

As shown in Figure 1, LED stepless dimming lamp, comprise stabilized voltage power supply 1, controller 2 and LED lamp 3, described stabilized voltage power supply 1 is by power input, stabilized voltage power supply plate and power output end 4 are formed, controller 2 comprises the control circuit board that is provided with single-chip microcomputer IC1, control button and LED lamp 3, the power output end of stabilized voltage power supply 1 and control circuit board, control button and LED lamp form and are electrically connected, be connected with a control button and LED1 on the control circuit board, two LED lamps of LED2, controller 2 also comprises shell, control circuit board is installed in the enclosure, and control button and two LED lamps 3 all are exposed to outside the shell.

As shown in Figure 2, control circuit board comprises power input and the LED lamp that is connected with single-chip microcomputer IC1, between single-chip microcomputer IC1 and power input, be connected with capacitor C 5, C6 and resistance R 2, between single-chip microcomputer IC1 and LED lamp, be connected with resistance R 3, R4 and triode Q2, Q3, single-chip microcomputer IC1 is connected with control button S1, and two LED lamps also are connected with resistance R 5, R6.

As shown in Figure 1 to Figure 3, the input ac voltage of stabilized voltage power supply plate is 220 volts, maximum continuous operation electric current is 500 milliamperes, after the stabilized voltage power supply plate is connected the 220V alternating voltage, behind transforming circuit, rectification circuit, filter circuit and voltage stabilizing circuit, press to single-chip microcomputer (MCU) control board output galvanic current.

MCU control board principle is described as follows:

1, after the MCU control board is connected direct current or AC power, obtain operating voltage, this moment is output not, and two LED lamps do not work, and are in off-mode.

2, press when the MCU control board has detected button, it is bright entirely promptly to control two LED lamps; After unclamping button, when detecting button and pressing for a long time, two LED lamp brightness deepenings; After unclamping button, when detecting button and pressing for a long time, the brightness of two LED lamps brightens; If after unclamping button, grow button again, this plate just can repeat the control of front.

3, all bright when two LED lamps, this plate detects button and is pressed by the short time, and the LED1 lamp is bright entirely, and LED2 does not work; If detecting button is pressed, just can enter off-mode, two LED lamps are all closed.
