Embodiment Construction

[0028] The present invention is further described below in conjunction with the accompanying drawings of the specification and embodiments of the present invention are given.

[0029] The main core idea of ​​the present invention is: the all-round and non-directional light source of the traditional fluorescent lamp used in the advertising light box and the LED tube light with 360° light is designed as a group of symmetrical light sources with certain directionality.

[0030] This tube-shaped LED lamp dedicated to advertising light boxes with a certain direction of light includes an outer sleeve 4, a radiator 3, and an LED emitter 5. It is characterized in that: the radiator 3 is a strip-shaped radiator. There are n LED emitters 5 evenly arranged, and the radiator 3 is sheathed in the outer sleeve 4 to form two directional strong light emission areas with the AA section of the radiator 3 as the center of symmetry, thereby forming Outer casing 4 strong light coverage area B.

Abstract

The invention relates to a tube-type LED lamp special for an advertising lamp box. The tube-type LED lamp special for the advertising lamp box comprises an outer sleeve pipe (4), a heat radiator (3) and LED light emitters (5), and is characterized in that the heat radiator (3) is a strip-shaped heat radiator, the n LED light emitters (5) are evenly arranged on two surfaces of the heat radiator (3), the heat radiator (3) is arranged in the outer sleeve pipe (4) in a penetrating and sleeved mode to form two orientated strong light emitting areas with the AA section of the heat radiator (3) as the symmetry center, and therefore an external strong light coverage area (B) emitting light on the outer sleeve pipe (4) is formed.

Description

technical field [0001] The invention relates to an LED lamp, in particular to a tubular LED lamp dedicated to an advertising light box, which belongs to the category of lighting lamps. Background technique [0002] The advertising light boxes that are commonly seen at present generally use strip fluorescent lamps or strip LED tubes as the light source of the light box. [0003] In practical application, it is found that the advertising light box using the above-mentioned conventional strip fluorescent lamp as the light source of the light transmission is found to be inhomogeneous in the use of the light box. The shadow band with the same cubic direction is obviously a defect for the best advertising effect. [0004] The inventor's in-depth research has found that the use of conventional strip fluorescent lamps or 360° luminous LED tube lamps as advertising light boxes produces the above-mentioned phenomenon of uneven brightness. The main reason is the inherent structure of ...
