本發明涉及半導體照明領域，特別涉及一種發光二極體光源模組。 The present invention relates to the field of semiconductor illumination, and in particular to a light emitting diode light source module.

發光二極體(Light Emitting Diode，LED)是一種可將電流轉換成特定波長範圍之光電半導體元件。發光二極體以其亮度高、工作電壓低、功耗小、易與積體電路匹配、驅動簡單、壽命長等優點，從而可作為光源而廣泛應用於照明領域。 A Light Emitting Diode (LED) is an optoelectronic semiconductor component that converts current into a specific wavelength range. The light-emitting diode is widely used in the field of illumination because of its high brightness, low operating voltage, low power consumption, easy matching with integrated circuits, simple driving, and long life.

當發光二極體適用於薄型光源模組時，通常會與一導光膜(LGF,light guide film)配合使用，導光膜為具有高折射率及光穿透率之透明薄膜，其表面具有不同疏密之網點微結構，從而實現將點光源轉換成面光源使用。然而，當發光二極體發出之光線直接進入導光膜時，會產生一定之光損導致光源模組之光利用率降低，且由於光線較為集中會造成光源模組整體上出光不均勻，進而影響其照明效果。 When the light emitting diode is suitable for a thin light source module, it is usually used together with a light guide film (LGF), which is a transparent film with high refractive index and light transmittance, and has a surface having Different dense mesh microstructures are used to convert point light sources into surface light sources. However, when the light emitted by the light-emitting diode directly enters the light guiding film, a certain light loss is generated, and the light utilization efficiency of the light source module is lowered, and the light source is unevenly distributed due to the concentrated light, thereby further Affect the lighting effect.
