請參閱圖7,本發明第二較佳實施方式的按鍵結構400與按鍵結構100大致相同,其不同之處僅在於,該發光組件30包括兩組發光元件,分別為第一組發光元件33及第二組發光元件35。第一組發光元件33與第二組發光元件35產生不同顏色的發光。於本較佳實施例中,該第一組發光元件33包括兩個白色LED,分別設於該開關模組20的兩側,該第二組發光元件35包括兩個紅色LED,分別設於該開關模組20的兩側並分別鄰近該兩個白色LED。另外,該兩個白色LED及該兩個紅色LED可交錯地設置於該開關模組20的兩側,使得其所發出的兩種顏色光可更均勻地擴散于周壁413,並均勻地從環形頂部411發出。該發光組件30包含發光元件的組數、各組發光元件的LED數量及發光顏色及排列方式也可為其它數量、顏色及排列方式並無特定的限制。 Referring to FIG. 7 , the button structure 400 of the second preferred embodiment of the present invention is substantially the same as the button structure 100 . The difference is that the light-emitting component 30 includes two sets of light-emitting components, respectively, a first group of light-emitting components 33 and The second group of light-emitting elements 35. The first set of light-emitting elements 33 and the second set of light-emitting elements 35 produce different colors of illumination. In the preferred embodiment, the first group of light-emitting elements 33 includes two white LEDs respectively disposed on two sides of the switch module 20, and the second group of light-emitting elements 35 includes two red LEDs respectively disposed on the The two sides of the switch module 20 are adjacent to the two white LEDs. In addition, the two white LEDs and the two red LEDs may be alternately disposed on both sides of the switch module 20 such that the two colors of light emitted by the two colors are more uniformly diffused on the peripheral wall 413 and uniformly from the ring. The top 411 is emitted. The number of sets of the light-emitting elements 30, the number of LEDs of each group of light-emitting elements, and the color and arrangement of the light-emitting elements 30 may be other numbers, colors, and arrangements without particular limitation.
可理解,該開關模組20可根據受按壓程度而包括第一按壓狀態及第二按壓狀態。當按壓件43按壓該開關模組20至第一按壓狀態時,該開關模組20控制第一組發光元件33發白光。當按壓件43繼續按壓該開關模組20至第二按壓狀態時,該開關模組20控制第二組發光元件35發出紅光。如此,該發光組件30可用以顯示電子裝置不同功能狀態。例如,當使用者使用該按鍵結構100來控制電子裝置進行拍攝時,當按壓件43按壓該開關模組20至第一按壓狀態時,第一組發光元件33發白光,顯示電子裝置進行對焦,當按壓件43繼續按壓該開關模組20至第二按壓狀態時,第二組發光元件35發出紅光,顯示電子裝置進行拍攝,故,使用者可根據導光件41顏色直觀地判斷出電子裝置的功能狀態。可以理解,該第二組發光元件35發光時,該第一組發光元件33可熄滅或同時發光。 It can be understood that the switch module 20 can include a first pressing state and a second pressing state according to the degree of pressing. When the pressing member 43 presses the switch module 20 to the first pressing state, the switch module 20 controls the first group of light emitting elements 33 to emit white light. When the pressing member 43 continues to press the switch module 20 to the second pressing state, the switch module 20 controls the second group of the light emitting elements 35 to emit red light. As such, the lighting assembly 30 can be used to display different functional states of the electronic device. For example, when the user uses the button structure 100 to control the electronic device to perform shooting, when the pressing member 43 presses the switch module 20 to the first pressing state, the first group of the light-emitting elements 33 emits white light, and the display electronic device performs focusing. When the pressing member 43 continues to press the switch module 20 to the second pressing state, the second group of the light emitting elements 35 emits red light, and the display electronic device performs shooting. Therefore, the user can intuitively determine the electronic color according to the color of the light guiding member 41. The functional status of the device. It can be understood that when the second group of light-emitting elements 35 emit light, the first group of light-emitting elements 33 can be extinguished or simultaneously emit light.
可理解,當按壓件43按壓該開關模組20至第一按壓狀態時,該開關模組20控制第一組發光元件33發閃爍狀態的白光,顯示電子裝置進行對焦,當按壓件43繼續按壓該開關模組20至第二按壓狀態時,第二組發光元件35發出閃爍狀態的紅光,顯示電子裝置進行拍攝。因此,使用者可根據導光件41的顏色或發光狀態直觀地判斷出電子裝置的功能狀態。 It can be understood that when the pressing member 43 presses the switch module 20 to the first pressing state, the switch module 20 controls the white light of the first group of the light-emitting elements 33 to blink, and the display electronic device performs focusing, and when the pressing member 43 continues to press. When the switch module 20 is in the second pressing state, the second group of light-emitting elements 35 emits red light in a blinking state, and the display electronic device performs imaging. Therefore, the user can intuitively determine the functional state of the electronic device according to the color or the light-emitting state of the light guide 41.
請參閱圖8,於本發明的第三較佳實施方式的按鍵結構500與按鍵結構400大致相同,其不同之處僅在於,該發光組件30可還包括第三組發光元件37,該按壓件43可由透明或半透明材料製成,該第三組發光元件37設置於該電路板10上,並容置於該第二容置腔47內,以發出光線進入導光件41,並沿周壁413傳遞至環形頂部411及按壓件43的按壓面436後發出。於本較佳實施中,該第三組發光元件37包含兩綠色LED分別於該開關模組20相對兩對稱設置。 Referring to FIG. 8, the button structure 500 of the third preferred embodiment of the present invention is substantially the same as the button structure 400, except that the light-emitting assembly 30 can further include a third group of light-emitting elements 37, the pressing member. 43 may be made of a transparent or translucent material, and the third group of light-emitting elements 37 are disposed on the circuit board 10 and housed in the second accommodating cavity 47 to emit light into the light guide 41 and along the peripheral wall. The 413 is transmitted to the annular top portion 411 and the pressing surface 436 of the pressing member 43, and is emitted. In the preferred embodiment, the third group of light-emitting elements 37 includes two green LEDs disposed symmetrically with respect to the switch module 20 .
該第三組發光元件37發光元件的LED數量及發光顏色及排列方式也可以是其它數量、顏色及排列方式並無特定的限制。可以理解,當第一組發光元件33及第二組發光元件35發光時,該第三組發光元件37也發光,使得整個按鍵結構100呈現出不同的顏色。 The number of LEDs and the color and arrangement of the light-emitting elements of the third group of light-emitting elements 37 may be other numbers, colors, and arrangements without particular limitation. It can be understood that when the first group of light-emitting elements 33 and the second group of light-emitting elements 35 emit light, the third group of light-emitting elements 37 also emit light, so that the entire button structure 100 exhibits different colors.
可以理解,該彈性件45可省略,該抵持部432本身由彈性材料,例如橡膠、泡棉等製成即可。 It can be understood that the elastic member 45 can be omitted, and the resisting portion 432 itself can be made of an elastic material such as rubber, foam or the like.
本發明較佳實施方式所述的按鍵結構100的周壁413形成與該發光組件30對應的弧形導光面416,另,於該遮光部417的外表面設有反光層,使得該發光組件30所發出光線經該導光面416進入導光件41,再由導光件41的環形頂部411發出,光線亮度更加均勻。再者,該發光組件30設置於導光件41外,可降低按鍵結構100的厚度,有利於減小電子裝置的體積。 The peripheral wall 413 of the button structure 100 of the preferred embodiment of the present invention forms an arcuate light guiding surface 416 corresponding to the light emitting component 30. Further, a reflective layer is disposed on the outer surface of the light shielding portion 417, so that the light emitting component 30 is provided. The emitted light enters the light guiding member 41 through the light guiding surface 416, and is emitted from the annular top portion 411 of the light guiding member 41, and the brightness of the light is more uniform. Moreover, the light-emitting component 30 is disposed outside the light guide 41, which can reduce the thickness of the button structure 100, and is advantageous for reducing the volume of the electronic device.
