Description

A LED fluorescent lamp with induction control

technical field

The utility model relates to an LED fluorescent lamp with induction control.

Background technique

LED products have broad market prospects. At present, the problem that LEDs face in the field of lighting is the problem of intelligent control. The traditional LED fluorescent tube is mainly after the lamp is powered on, and the lamp is always fully bright. There are two ways. Although LED fluorescent lamps can save nearly half of the electric energy compared with traditional fluorescent tubes, it is still a waste of electric energy for places that require long-term lighting requirements but relatively few people or objects pass by.

Utility model content

The technical problem to be solved by the utility model is to provide a new type of LED fluorescent lamp with induction control. The LED fluorescent lamp with induction control adjusts its own working mode based on automatic induction, and has a good energy-saving effect.

The technical solution of the utility model is as follows:

An LED fluorescent lamp with induction control, including a single-chip microcomputer, an inductor, a constant current power supply, a driver and a lamp board of the LED fluorescent lamp;

The input terminal of the constant current power supply is connected to the mains, the output terminal of the constant current power supply is connected to the input terminal of the driver; the output terminal of the driver is connected to the light board of the LED fluorescent lamp;

The sensor is connected with the signal input terminal of the single chip computer; the control terminal of the driver is connected with the output terminal of the single chip computer.

The driver is a PWM driver.

The sensor is a microwave sensor, a human body infrared sensor, a sound-activated switch or a light-activated switch. Beneficial effect:

The LED fluorescent lamp with induction control of the utility model can automatically identify whether there are people or vehicles in the current environment because of the addition of sensors, so as to determine whether to turn on the LED fluorescent lamp. When there is no one, the brightness will be automatically weakened or within a predetermined time Turn off to realize energy saving. The LED fluorescent lamp with induction control of the utility model is especially suitable for a place where long-term lighting requirements are required, but relatively few people or vehicles pass by, and has a good energy-saving effect.

Description of drawings

Fig. 1 is a structural block diagram of the LED fluorescent lamp with induction control of the present invention.

Detailed ways

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

Example 1:

As shown in Figure 1, an LED fluorescent lamp with induction control includes a single-chip microcomputer, an inductor, a constant current power supply, a driver and a lamp board of the LED fluorescent lamp;

The input terminal of the constant current power supply is connected to the mains, the output terminal of the constant current power supply is connected to the input terminal of the driver; the output terminal of the driver is connected to the light board of the LED fluorescent lamp;

The sensor is connected with the signal input terminal of the single chip computer; the control terminal of the driver is connected with the output terminal of the single chip computer.

The driver is a PWM driver.

The sensor is a microwave sensor, a human body infrared sensor, a sound-activated switch or a light-activated switch.

The constant current power supply converts 220V AC power into 24V DC power supply to the PWM driver, and at the same time provides power to the microcontroller after stepping down. The PWM driver is a DC-DC driver, working at 24V voltage, and controls the working state of the LED fluorescent lamp through PWM pulses (such as full on, , turn on parts and turn off lights, etc.).

A typical working mode is: firstly, after the power is turned on, the LED fluorescent lamp is always on for 5 seconds to 5 minutes, and the brightness slowly decreases to the minimum brightness originally set by the user. If the sensor senses that people, cars or other objects pass by, the light becomes fully bright again.
