Description

Technical Field

[0001] The utility model relates to the technical field of LED light surfaces, in particular to a multifunctional LED surface light source. Background Art

[0002] LED is the abbreviation of light emitting diode, which is a compound semiconductor component. LED lighting is light emitting diode lighting, which is a semiconductor solid light-emitting device. LED has the characteristics of low energy consumption, small size, pollution-free, fast response, and low driving voltage. The general lighting field is the most important application field in the downstream of the LED lighting industry chain, including traditional application fields such as home lighting, commercial lighting, industrial lighting, municipal road lighting, and landscape lighting. With the continuous development of the LED lighting industry, innovative technologies and products have continuously expanded the downstream application market, and more application scenarios are gradually being developed, for example, LED lights are used in advertising light boxes.

[0003] After searching, it is found that the common practice of advertising light boxes on the market is to use one-meter-long LED hard light strips, which are connected by electronic wires, spaced a certain distance apart, and spread in parallel inside the light box. The circuit board of this LED hard light strip is a hard aluminum-based circuit board, which can be arranged on a flat, regular square surface. If the surface to be applied is a curved surface (for example: a cylindrical surface), it cannot be realized because the base material is hard and cannot be bent. Secondly, its voltage is DC24V. Due to the willingness of the circuit design, after connecting 3-5 meters, the brightness at the end is obviously different from the front end, so it cannot be extended too long. Finally, the light source of this light strip is sparsely distributed, and the light-emitting angle of the LED is changed through the lens to compensate for the bright interval caused by the large interval (commonly known as "ribbon frame"). However, after refraction through the lens, the brightness of the LED is also reduced, resulting in too low light efficiency and insufficient energy saving.

[0004] Therefore, we provide a multifunctional LED surface light source to solve the above problems. Utility Model Content
