Embodiment 1

[0027] An LED Wood lamp includes a housing, a magnifying glass and a power supply. see figure 1 , 2 .

[0028] Its innovation is: the housing is composed of a circular viewing head 1 and its lower handle 6, and the housing is made in one piece in this embodiment. The magnifying glass 11 is embedded on the outer surface of the observation head. The inner surface of the observation head is positioned at the outer circumference of the magnifying glass, and a group of purple LED3 (wavelength is 365nm) is evenly distributed by the ring lamp holder 2, preferably 3-8 (modified). In this embodiment, five purple LEDs are arranged. The outer surface of the ring light frame is conical, and the purple light LEDs are installed perpendicular to the outer surface of the ring light frame, so that a plurality of purple light LEDs in the ring shape are gathered downwards and installed on the ring light frame, so that each purple light LED The light is gathered in the observation area with ...

Embodiment 2

[0031] see image 3 , 4 . A group of white light LEDs 17 are also installed on the ring light frame, and the white light LEDs and purple light LEDs are spaced apart from each other and evenly distributed on the ring light frame. For the sake of appearance, a focusing mirror covered on the surface of the white light LED is also installed on the ring lamp holder. In this embodiment, three purple LEDs and three white LEDs are provided. A switch 18 of a purple light LED and a switch 18 of a white light LED are arranged outside the upper end of the handle. When the white light LED is turned on, it can be used for general dermatological examinations.

Abstract

The invention relates to an LED wood lamp which comprises a shell, a magnifier and a power supply. The invention is characterized in that the shell is composed of a round viewing head and a handle below the viewing head; the magnifier is embedded in the external surface of the viewing head; the outer circumference of the magnifier on the internal surface of the viewing head is evenly distributed with a set of purple light LEDs through an annular lamp bracket; and the tail end of each purple light LED is installed on an annular radiating block in the annular lamp bracket. The invention has the advantages of scientific and reasonable design, compact structure, light weight, convenient application, beautiful appearance, good effect, long service life and higher creativity, is an updated substitute product for the prior wood lamp, and has wide market prospects.

Description

technical field [0001] The invention belongs to the field of medical equipment, in particular to an LED Wood lamp. Background technique [0002] As a commonly used detection device in clinical dermatology, Wood lamp is widely used. It is very useful for the diagnosis of tinea capitis, tinea versicolor, pityrosporum folliculitis, erythrasma, trichophyton axillae, acne, vitiligo, chloasma and other abnormal pigmentation diseases, some skin tumors, abnormal porphyrin metabolism diseases, etc. the value of. Its principle is to obtain 320-400nm long-wave ultraviolet rays through a filter containing nickel hydride, and perform clinical diagnosis according to the fluorescence response of the lesion to WOOD light. Wood's lamp has the advantages of low cost, short treatment time, quick results, and high efficiency. It does not directly touch the inspection site during operation, and has the advantages of no pain and no infection. It is suitable for patients of all ages. [0003] A...
