Problems solved by technology
[0010] However, such a conventional LED lighting device has several problems: since light is emitted from the LED mounted on the PCB in a lateral direction, the luminous efficiency of the reflective film is lowered, and during light emission, the formation for preventing hot spots is performed. Phenomenon of light-shielding pattern steps to increase the number of steps, resulting in an increase in production costs
However, such lighting devices have not been reported

The present disclosure provides a lighting device comprising: a reflective element layer; an optical resin layer formed on the reflective element layer; a transparent electrode film layer formed on the optical resin layer; and a plurality of light-emitting units formed on the lower surface of the transparent electrode film layer. The lighting device allows the fundamental cause of the hot spot phenomenon to be eliminated, shows excellent luminous efficiency by efficiently performing the function of a surface light source, and enables the kinds of raw materials and the number of production processes to be reduced by eliminating the use of a PCB board and selectively applying second reflective patterns.
Description
[0001] Related Technology Cross-References [0002] This application claims priority from Korean Patent Application No. 10-2015-0039870 filed in the Korean Intellectual Property Office on Mar. 23, 2015, the entire contents of which are hereby incorporated by reference. technical field [0003] The invention relates to a lighting device. Background technique [0004] With the recent development of technology, in order to increase luminous efficiency, lighting devices using various light sources have adopted appropriate light sources according to their electrical properties. [0005] These lighting devices have been used in a variety of applications, including backlight units for flat panel displays, interior lights, and headlights, fog lights, reverse lights, position lights, license plate lights, Tail lights, brake lights, turn signals, emergency warning lights and interior lights. [0006] Meanwhile, a light-emitting diode (LED) is an element that converts electrical sign...
