Embodiment 1

[0033] Please refer to figure 1 , Embodiment 1 of the present invention is: a light source structure of a hair removal instrument, including a connected lamp board 2 and an LED assembly, the LED assembly includes a plurality of LED lamp strings 1 arranged side by side on the lamp board 2, each The LED lamp string 1 is composed of a number of first LED chips 11 and a plurality of second LED chips 12 connected in series, the number of the first LED chips 11 is smaller than the number of the second LED chips 12, and the number of the first LED chips 11 is smaller than that of the second LED chips 12. The wavelength of the LED chip 11 is 700nm-760nm, the wavelength of the second LED chip 12 is 900nm-960nm, and the wavelength value of the second LED chip 12 on each LED light string 1 is along the The direction of movement decreases.

[0034] In this embodiment, the number of the first LED chips 11 on the LED light string 1 is one, and the number of the second LED chips 12 on the L...

Embodiment 2

[0036] Please refer to figure 2, the second embodiment of the present invention is: the number of the first LED chips 11 on each LED light string 1 is multiple. Specifically, in this embodiment, all the first LED chips 11 on each LED light string 1 The number of the first LED chips 11 is 4, and the number of the second LED chips 12 on the LED light string 1 is 21; more specifically, the value of the wavelength of two adjacent LED chips The difference is 3nm, and the difference between the wavelengths of two adjacent first LED chips 11 is 20nm; that is to say, the wavelength of the first LED chips 11 on each LED light string 1 is 760nm in turn. , 740nm, 720nm and 700nm, the wavelengths of the second LED chips 12 on each LED light string 1 are 760nm, 757nm, 754nm, . . . , 709nm, 706nm, 703nm and 700nm.

Embodiment 3

[0038] Please refer to image 3 with Figure 4 , the third embodiment of the present invention is: the number of the first LED chips 11 on two adjacent strings of LED light strings 1 is different, that is to say, the number of the first LED chips 11 on a single LED light string 1 The number of one LED chip 11 can be one or more; optionally, in the LED light string 1 with multiple first LED chips 11, the first LED chips 11 can be in a continuous sexual arrangement (such as image 3 shown), can also be in a non-continuous arrangement (such as Figure 4 shown).

[0039] To sum up, the light source structure of the hair removal device provided by the present invention has the characteristics of uniform light output, multi-function, good hair removal effect, outstanding cosmetic effect and rich structural styles.

Abstract

The invention discloses a light source structure of a hair removal instrument. The light source structure comprises a lamp panel and an LED assembly which are connected, wherein the LED assembly comprises a plurality of LED lamp strings arranged on the lamp panel side by side; each LED lamp string is formed by connecting a plurality of first LED chips and a plurality of second LED chips in series;the number of the first LED chips is smaller than or equal to 4; the number of the second LED chips is larger than or equal to 7 and smaller than or equal to 20; the wavelength of each first LED chipis 700-760 nm; and the wavelength of each second LED chip is 900-960 nm. The plurality of first LED chips with the wavelengths of 700-760 nm are arranged in the plurality of second LED chips with thewavelengths of 900-960 nm in a mixed mode, and the first and second LED chips are connected in series to form the LED lamp strings; and the first LED chips arranged in the second LED chips in a mixedmode can disperse light emitted by the second LED chips, so that the wavelength of light emitted by the LED assembly is mainly 900-960 nm and secondarily 700-760 nm, the light of900-960 nm has good hair removal effect, the light of 700-760 nm has the effects of tightening the skin and resisting aging, and the functional diversity is enriched.

Description

technical field [0001] The invention relates to the field of hair removal instruments, in particular to a light source structure of the hair removal instrument. Background technique [0002] Laser hair removal is a common cosmetic method, and the wavelength of the laser is usually around 950nm. Because the laser has the characteristics of monochromaticity and high luminous flux, the efficiency of hair removal is relatively high. However, high-power lasers have the disadvantages of high cost, harsh conditions, and high maintenance costs in the later period. Generally speaking, the cost performance is relatively low. [0003] There are also devices on the market that use IPL strong light for human body hair removal and beauty. The light source used is generally a high-brightness white light source. This light source has the characteristics of wide spectrum and large luminous flux. The light of the required band is irradiated on the skin for hair removal. However, it only sel...
