The Wood's lamp is an ultraviolet lamp that emits light at a wavelength of 365 nm (nanometers). Certain molecules in fungi and bacteria have unique chemical structures that, when excited by the light of this wavelength from the Wood's detection lamp, emit fluorescence of different colors (e.g., porphyrins emit pink fluorescence when excited). Therefore, high-brightness Wood's lamp examination is widely used in dermatology. Based on the color of the emitted fluorescence, it can quickly determine the type and extent of infection for certain bacteria and fungi.
The high-brightness Wood's lamp, Wood's diagnostic lamp CX-WD, is used in a dark room. The light source is placed about 6-8 centimeters away from the skin, directed at the affected area. The operator (doctor) observes the skin through the Wood's lamp, as different skin conditions emit different fluorescent colors.
Imported high-brightness Wood's lamp tubes, with specialized filters, ensure more stable detection light output. This reduces background darkness and avoids the influence of visible light on fluorescence, resulting in clearer image contrast.

   1. Conditions such as depigmented nevi, pityriasis alba, tuberous sclerosis, post-inflammatory hypopigmentation spots, and leprosy hypopigmentation spots appear yellow-white or gray-white under the Wood's lamp. Tinea versicolor appears brown or yellow-white, while the pale white lesions of nevus depigmentosus do not show up.  

2. When the skin is rubbed or turns red, observe whether the white spots also turn red or if the white spots become more apparent. The latter indicates nevus depigmentosus.  
3. Skin sensation examination, including tests for temperature, pain, and touch. The patient's sensation is normal, whereas leprosy white spots often exhibit impaired superficial sensation, including reduced or even absent sensation.  
4. The isomorphic reaction of vitiligo under the high-brightness Wood's lamp: On normally pigmented skin in the patient's deltoid area, after routine disinfection with alcohol, a crosshatch pattern is made with a sterilized vaccination needle, measuring 1 cm. After one month, check the scratched area. Depigmentation indicates a positive result, while no change in pigmentation indicates a negative result. Based on the scratch test, the following conclusions can be drawn: A positive isomorphic reaction suggests that the lesions are mostly expanding, respond poorly to photochemotherapy, but respond well to glucocorticoid treatment.


Advantages of the high-brightness Wood's lamp, Wood's diagnostic lamp CX-WD:
1. The examination does not involve direct contact with the affected area, offering advantages such as painlessness and non-infectiousness, making it suitable for patients of all ages.  
2. The Wood's diagnostic lamp is known as the "microscope" of the skin. It can accurately detect the amount of melanin loss, distinguish between complete and incomplete vitiligo, and screen for lesions that are not visible to the naked eye.
3. The Wood's diagnostic lamp makes vitiligo diagnosis simpler. The examination process involves no blood drawing or pain, and the results are fast and accurate.
4. The high-brightness Wood's lamp is specifically designed for dermatologists. It uses a plug-in power supply for convenience. The Wood's diagnostic lamp WD-CX02 uses imported lamp tubes, ensuring a long lifespan and flicker-free light.
