Embodiment 1

[0075] Structure of Portable LED Light Therapy Apparatus

[0076] See Figure 4 The overall schematic diagram of the portable light-emitting diode phototherapy instrument (hereinafter referred to as the phototherapy instrument) is shown.

[0077] The phototherapy instrument 1 includes a body 11 and a probe 12. The panel of the body 11 has a time setting switch 111 for setting the light time of the phototherapy instrument 1 in use; a start button 112 for starting the phototherapy instrument; charging The indicator light 113 is used to indicate the charging status; and the low battery indicator light 114 is used to indicate the low battery status.

[0078] This light therapy device uses a portable power source, see Figure 5a The schematic diagram of the power supply of the phototherapy instrument shown in the figure shows that the back of the body 11 of the phototherapy instrument 1 has a power switch 117 for turning on or off the power of the phototherapy instrument; there i...

[0090] Clinical Results of Light Therapy Apparatus

[0091] A four week study was carried out on voluntary users (face) using the portable LED phototherapy device described in Example 1. The result is as follows:

[0092] Description: 1) There are two types of acne (inflammatory and non-inflammatory). Individuals with acne typically have both inflammatory and non-inflammatory acne. Both inflammatory and non-inflammatory acne on the face of each volunteer were treated with phototherapy and followed during the study. However, in the following table, the numbers of inflammatory acne and non-inflammatory acne on the face were counted separately (counted as 0 if acne disappeared).

[0093] Table 3) Changes of the total number of inflammatory acne over time (the number of each group is 5, and the control group is not treated; for convenience, the total number of inflammatory acne before treatment is standardized (Normalize) to be 100 ; standard deviation = + / -5)

Abstract

The invention provides an LED light therapeutic apparatus, the probe of which can include a special lens array combination to strengthen the illumination effect; a blue LED and a red LED are combinedas the light source of the LED light therapeutic apparatus; and a light beam deformation thin or mechanical pupillar is used for regulating the shape or size of the illumination treatment zone.

Description

technical field [0001] The invention relates to the field of dermatology phototherapy or cosmetic technology, in particular to the structure of a light-emitting diode phototherapy instrument. Background technique [0002] Acne is a disease of the sebaceous glands with clinical symptoms of distorted sebum, exfoliation and inflammation of the epidermis. Various factors can cause acne, such as bacterial growth; overexposure to the sun's ultraviolet rays; adolescents who secrete a lot of hormones, etc. figure 1 The process of acne formation is shown. [0003] Often doctors prefer antibiotics as the treatment for acne, or in combination with an old-fashioned light therapy machine, a procedure such as figure 2 shown. But because of the resistance brought about by the regular use of antibiotics, many patients suffer from ineffective treatment and side effects. [0004] Contain a large amount of porphyrins in the acne-causing bacterium propionibacterium acnes (P.Acne), and porp...
