Novel LED surface light source structure

Abstract

The invention belongs to the technical field of optical sensing, and particularly relates to a novel LED surface light source structure. The novel LED surface light source structure comprises a radiating support, an LED lamp strip, a light guide plate and a reflecting layer. A lamp holder is used for supporting a surface light source. The novel LED surface light source structure has the beneficial effects that a line light source emitted by LED lamp beads is converted into the surface light source through the optical effect of the light guide plate, the optical efficiency is improved, and the light-emitting uniformity is improved; heat generated on a PCBA board and the LED lamp beads can be effectively emitted out, therefore normal work environments of the PCBA board and the LED lamp beads can be ensured, and the service life is prolonged; the LED lamp strip comprises a temperature detection module, appearing of the instant high temperature condition of the light source can be avoided, and the safety protection effect is achieved; and the novel LED surface light source structure has the obvious beneficial effects of being soft in emitted-out light, free of hurting the eyes, low in power dissipation, natural in light, high in optical purity, long in service life, high in cost performance and the like.

Description

technical field [0001] The invention belongs to the technical field of light sensing, and in particular relates to a novel LED surface light source structure. Background technique [0002] The surface light source is a new lighting mode compared to the LED point light source and the light source of ordinary lamps. Usually there is a light guide plate, a layer of reflective layer is placed between its side and the PCBA board, and a light outlet is preset on the reflective layer corresponding to the position of the LED light source, but the existing technology has problems of low light guide efficiency, light energy loss and transmission The shortcoming of poor thermal effect, at present, the technical problem that the industry generally pays attention to and researches is how to improve the high light rate and how to reduce the loss of light energy. Contents of the invention [0003] The present invention overcomes the deficiencies of the prior art and proposes a novel L...
