Abstract

The invention discloses an optical assembly and an illuminating device. The optical assembly comprises a body, a light entering surface and a light exiting surface. Concave space is formed in the bottom of the body. The light entering surface is defined by the concave space of the body, so that light can enter the light entering surface, moreover, the light entering surface is provided with an annular region, a plurality of micro-structures are arranged on the annular region of the light entering surface at least, and each micro-structure is provided with a cambered surface. The light exiting surface is formed on the outer surface of the body, and the bottom edge of the outer surface is adjacently connected to the outer edge of the bottom of the body. The illuminating device comprises the optical assembly and a light source. By the optical assembly and the illuminating device, yellow ring circumstances can be reduced, the utilization rate of light is improved, and the problem of central bright spots is solved.

Description

【Technical field】 [0001] The invention relates to an optical component and an illuminating device with the optical component, in particular to an optical component with microstructures on the light-incident surface and an illuminating device with the optical component. 【Background technique】 [0002] As the backlight modules of light-emitting diode (LED) TVs continue to meet various requirements such as large size, light weight, thin thickness, and high performance, how to further improve these design requirements has become an important issue in the development of LED TV backlight modules in recent years. new trend. At present, when the light-emitting diode used in the LED backlight module contains phosphor and because the LED is very close to the diffuser plate, when the light passes through the backlight lens, it is easy to generate uneven imaging on the diffuser plate and produce a yellow circle phenomenon, which affects the display quality of the TV. [0003] Such as ...
