led multi-faceted light emitting plane light source

Abstract

The invention discloses an LED multi-side lighting planer light source which comprises an LED array, an optical lens array, a condensing, diffusing and transmitting board and a transparent integral support plate. The LED array consists of multiple LEDs in arrangement. Each non-imaging secondary optical lens comprises an upper concave lens portion, a lower concave lens portion, four angles of refraction and reflection, four edges of refraction and reflection and four internal vertical sides; the four angles of the refraction and reflection of the optical lens are in rectangular arrangement, the four edges of refraction and reflection of the optical lens are arranged on four sides of the rectangle, the four internal vertical sides and the concave lens consisting of the upper concave lens portion and the lower concave lens are disposed in the middle of the rectangle, and the LEDs are disposed in the lower portion of the space formed by the four internal vertical sides of the optical lens. The LED multi-side lighting planer light source has the advantages of simple structure, small size, capability of reflecting a little light to the back, and good light intensity and uniformity within the total lighting area.

Description

technical field [0001] The invention relates to the technical field of LED planar lamps, in particular to an LED multi-faceted planar light source. Background technique [0002] Semiconductor lighting fixtures tend to be mature, among which LED street lamps, LED floodlights, LED bulb lamps and other products have been widely used. However, the design technology of LED lamps is in the process of development, and the main problems focus on LED light output efficiency and light output methods. . At present, the ordinary LED flat light technology is not yet fully mature, and the main problems are: the technical problem of the uniformity of the LED light source to form a flat light; the general-purpose LED flat light is single-sided light, and when installed on the top of the house, the top of the lamp is a dark area , affecting the overall brightness or lighting effect in the house; the direct structure LED flat light is adopted, and its reflector fully reflects the light, so t...

Problems solved by technology

At present, the ordinary LED flat light technology is not yet fully mature, and the main problems are: the technical problem of the uniformity of the LED light source to form a flat light; the general-purpose LED flat light is single-sided light, and when installed on the top of the house, the top of the lamp is a dark area , affecting the overall brightness or lighting effect in the house; the direct structure LED flat light is adopted, and its reflector fully reflects the light, so that there is no light on the back of the lamp; the reflector of the side-entry LED flat light fully reflects light, and there is no light on the back; General-purpose LED flat panel lights are all made of metal backplanes, and the light cannot be transmitted
