Light Therapy Lamp
A light therapy lamp, also known as a SAD lamp (Seasonal Affective Disorder lamp), is a device used to treat Seasonal Affective Disorder and other conditions by exposing a person to bright light.
Material
Typically constructed with:
- Housing: Often made of plastic, sometimes metal for durability.
- Light Source: Originally fluorescent tubes, now predominantly LEDs due to energy efficiency, longevity, and lack of UV emission. LEDs are chosen for specific wavelengths.
- Diffuser: A panel to spread the light evenly and reduce glare. Usually made of acrylic or polycarbonate.
- Electronics: Internal circuitry for power regulation and, in some models, timer functions and adjustable settings.
- Stand/Base: Plastic or metal for stability and positioning.
Purpose
The primary purpose is to alleviate symptoms associated with:
- Seasonal Affective Disorder (SAD): A type of depression related to changes in seasons, typically occurring in the fall and winter due to reduced sunlight.
- Non-Seasonal Depression: Can be used as an adjunct treatment for major depressive disorder.
- Sleep Disorders: Helps regulate the body's circadian rhythm, useful for shift work sleep disorder and delayed sleep phase syndrome.
- Jet Lag: Assists in resetting the body clock after travel across time zones.
- Low Energy Levels: Some individuals use them to combat fatigue and improve alertness.
Function
Light therapy lamps function by mimicking outdoor light. The bright light exposure is believed to:
- Suppress Melatonin Production: Melatonin, a hormone regulating sleep, is produced in higher amounts in darkness. Light exposure reduces melatonin levels, promoting wakefulness.
- Influence Serotonin Levels: Light may increase serotonin levels, a neurotransmitter associated with mood regulation.
- Regulate Circadian Rhythm: Exposure at specific times can help synchronize the body's internal clock.
- Impact Brain Activity: Light exposure affects brain regions involved in mood and sleep.
Usage Scenarios
- Home: Most commonly used in the morning, typically for 20-30 minutes.
- Office: Some individuals use them at work to combat low energy and improve focus.
- Travel: Portable models can be used during travel to manage jet lag.
- Therapy Settings: Used in clinical settings under the guidance of healthcare professionals.
Common Types
- Desktop Lamps: The most common type, designed to sit on a desk or table.
- Wall-Mounted Lamps: Useful for space saving and consistent positioning.
- Light Boxes: Larger panels that provide broader light coverage.
- Visors/Glasses: Worn like glasses, delivering light directly to the eyes (less common, require specific wavelengths).
- Dawn Simulators: Gradually increase light intensity over a period of time, mimicking sunrise (often used as alarm clocks).
Specifications to Consider
- Light Intensity: Measured in Lux. 10,000 Lux is a common recommendation for treating SAD.
- Wavelength: Full-spectrum white light is generally recommended, with a focus on blue wavelengths (400-500 nm).
- UV Emission: Should emit minimal to no UV radiation.
- Size & Portability: Consider the intended usage scenario.
- Timer Function: Allows for controlled exposure duration.
- Adjustable Settings: Some models offer adjustable intensity and color temperature.
The declared goods, a “sad light therapy lamp,” is a device designed to address Seasonal Affective Disorder (SAD) and potentially other conditions through exposure to specific wavelengths of light, likely ultraviolet. It functions as a therapeutic light source, intended for medical or wellness applications.
Based on the provided reference material, the following HS codes are relevant:
-
8539490040: This HS code covers “Ultraviolet or infrared lamps; arc lamps: Other Ultraviolet lamps.” Given that a “sad light therapy lamp” utilizes ultraviolet lamps for therapy, this is a highly relevant classification.
- 85: Electrical machinery and equipment and parts thereof.
- 39: Electrical filament or discharge lamps, including sealed beam lamp units and ultraviolet or infrared lamps; arc lamps; light-emitting diode (LED) light sources; parts thereof.
- 49: Ultraviolet or infrared lamps; arc lamps.
- 00: Other.
- 40: Other Ultraviolet lamps.
-
9019104000: This HS code covers “Mechano-therapy appliances; massage apparatus; psychological aptitude-testing apparatus; ozone therapy, oxygen therapy, aerosol therapy, artificial respiration or other therapeutic respiration apparatus; parts and accessories thereof: Mechano-therapy appliances; massage apparatus; psychological aptitude-testing apparatus; parts and accessories thereof: Other: Electrically operated apparatus and parts thereof.” If the lamp is marketed as a therapeutic device beyond simple light emission (e.g., mood enhancement, psychological benefit), this code may be applicable.
- 90: Instruments and apparatus which measure or check for physical or chemical analysis; measuring or checking instruments; precision balancing instruments; weights of precise measurement; optical, photographic, cinematographic, measuring, checking, precision, medical or surgical instruments and apparatus; parts and accessories thereof.
- 19: Mechano-therapy appliances; massage apparatus; psychological aptitude-testing apparatus; ozone therapy, oxygen therapy, aerosol therapy, artificial respiration or other therapeutic respiration apparatus; parts and accessories thereof.
- 10: Mechano-therapy appliances; massage apparatus; psychological aptitude-testing apparatus; parts and accessories thereof.
- 40: Other: Electrically operated apparatus and parts thereof.
-
9031808085: This HS code covers “Measuring or checking instruments, appliances and machines, not specified or included elsewhere in this chapter; profile projectors; parts and accessories thereof: Other instruments, appliances and machines: Other Other.” If the lamp includes features for measuring light intensity, duration, or other parameters related to therapy effectiveness, this code could be considered.
- 90: Instruments and apparatus which measure or check for physical or chemical analysis; measuring or checking instruments; precision balancing instruments; weights of precise measurement; optical, photographic, cinematographic, measuring, checking, precision, medical or surgical instruments and apparatus; parts and accessories thereof.
- 31: Measuring or checking instruments, appliances and machines, not specified or included elsewhere in this chapter; profile projectors; parts and accessories thereof.
- 80: Other instruments, appliances and machines.
- 80: Other.
- 85: Other Other.
Regarding HS code 8539490040, please note the need to verify that the lamp utilizes ultraviolet lamps.
