Description

LED lighting fixtures for adjuvant treatment of depression

technical field

The utility model belongs to the technical field of electric light sources, in particular to a lamp suitable for auxiliary treatment of depression, in particular to a dimmable blue LED lighting lamp suitable for use in hospitals and homes.

Background technique

With the acceleration of people's life rhythm and the gradual improvement of the quality of life, the pressure of life and society also increase. Mental problems occur frequently, and depression is a typical mental illness in modern society, accompanied by a series of problems such as insomnia and emotional loss. The problem of depression has attracted the attention of the whole society, and a variety of treatment methods go hand in hand. Here we introduce a new concept of auxiliary treatment - light therapy.

Light is a very important element in human life. While light provides energy and aids visibility, it also has biological effects. The spectral lines of different bands will have different physiological effects on the human body. The research on the biological effects of the human body has just begun in the world in recent years. The human body will have different physiological responses to different spectral components and different illuminance. The study found that the blue light component between 460nm and 480nm has the most obvious physiological effects on the human body, and the light intensity above 400lx will produce obvious physiological effects, which is beneficial to the rehabilitation treatment of depression.

Contents of the invention

The purpose of the utility model is to provide an LED lighting fixture that can assist in the treatment of depression.

The LED lighting fixture proposed by the present invention adopts a high color temperature blue light-emitting diode (LED) as a light source, and is specifically composed of an LED light-emitting array, a power supply, a control panel and a control circuit, and its structure is shown in FIG. 1 . Wherein, the light source 1 is connected with the control panel 2, the control panel 2 is connected with the control circuit 3, and the control circuit 3 is connected with the LED array 4, wherein the LED adopts 460nm-480nm blue LED, and the dimming adopts PWM dimming mode.

The light intensity of the lamp of the utility model is adjustable, and has more suitable LED light-emitting characteristics: good spectrum uniformity, strong central light, and easy control of the light-emitting direction. Select the blue LED light source array with a peak wavelength of 460nm-480nm, so that the lamps can not only reflect high efficiency and energy saving, but also have the function of auxiliary treatment for patients with depression. Using PWM dimming. PWM (Pulse Width Modulation, pulse width modulation) dimming. It uses the principle of visual suspension of the human eye to periodically control the conduction current of the LED to switch back and forth between zero current and a constant rated operating current with a certain frequency and duty cycle, thereby adjusting the brightness. This dimming method There will be no color shift, and it is better than the method of changing the current to adjust the light in the field of lighting applications. Light intensity and light time can be preset by software program. Multi-level different light intensity can be set, usually can be set to 3 levels. It also presets the timing switch time to control the luminous time, which is used for auxiliary treatment of different degrees of depression.

Detailed ways

In the utility model, all parts of the device are conventional parts in the field, and the size of each part is determined according to the actual use requirements. The LED array uses blue LEDs with a peak wavelength of about 470nm, and is equipped with a suitable light-emitting lens. The control circuit is a conventional PCB board; the lamp is an ordinary LED array lamp; the power supply is an ordinary 220V AC mains.

The connection method is shown in the attached figure: connect the power supply 1 to the power terminal of the control panel, and the lamp to the output terminal of the control circuit 3, and then the preset and control of the light output of the lamp can be realized through the switch button.

Wherein, the microprocessor is adopted in the control circuit 3, and the microprocessor is equipped with control software to control the light intensity and light time through the PWM dimming mode. Specifically, the light intensity is preset to 3 levels to be suitable for different Adjuvant therapy for patients with severe depression.
