Abstract

The invention relates to a direct type LED television, which comprises an LED module, a plurality of light guide elements and a display panel. The LED module comprises a circuit board and a plurality of LEDs arranged as an array on the circuit board. The light guide elements are arranged on the circuit board, and each light guide element comprises a top wall and a hollow containing part connected with the top wall. One LED is contained in each containing part. Each top wall comprises a light incidence surface close to the containing part and a light emergence surface opposite from the containing part, the light incidence surface is provided with a concave lens facing the LED, the light emergence surface is provided with a convex lens, and the concave lens and the convex lens are jointly used for diffusing the light emitted by the LED. The display panel is arranged over the light guide elements and receives LED light transmitted by the light guide elements. The invention also relates to the LED light source module.

Description

technical field [0001] The invention relates to an LED light source module and a direct-down LED TV. Background technique [0002] Light emitting diodes (LEDs) have been widely used as point light sources. At present, the light guide element of the LED is mainly a flat diffuser plate with particles inside the diffuser plate for diffusing light. The diffusion plate and the LED need to maintain a certain distance so that the heat of the light will not be excessively concentrated and cause a hot spot (Hot Spot). However, with the demand for thinner electronic products, such as thinner LED TVs, it is difficult to further limit the distance between the diffuser plate and the LEDs. Contents of the invention [0003] In view of this, it is necessary to provide an LED light source module and a direct-lit LED TV that can overcome the above-mentioned problems. [0004] An LED light source module includes an LED module and a plurality of light guide elements. The LED module inclu...
