Embodiment Construction

[0016] refer to image 3 , 4, the ultra-long indicator light of the computer case of the present invention includes a long cylindrical light guide column 20 made of transparent material arranged on the panel, and a plurality of triangular prisms are integrally formed on the rear side of the light guide column 20 21 , the light-emitting diode 10 is disposed on the back side of the light guide bar 20 facing the light guide bar. The lateral length of the light guide column L w In the case of greater than 50mm, in order to achieve uniform illumination and shorten the distance in the entire length range, the relevant knowledge of optics is applied, and the LED lamp 10 can be placed on one side of the light guide column 20, and its incident angle β can be adjusted. The light emitted by the LED lamp 10 can cover the entire light guide column 20 , and then emit from the front end 22 of the light guide column 20 through the refraction and reflection of many small triangular prisms 21 ...

Abstract

An ultra-long indicating lamp for computer casing is composed of a cylindrical long light-transferring column made of transparent material and arranged on panel, and integrally made multiple triple prisms behind said light-transferring column. Its advantages are long length more than 50 mm, and uniform brightness.

Description

【Technical field】 [0001] The invention relates to an indicator light of a computer case. 【Background technique】 [0002] As we all know, computer cases are provided with indicator lights with various indicating functions, such as power indicator lights, sleep indicator lights, hard disk indicator lights, and the like. The basic structure of the previous indicator light is a light-emitting diode (abbreviated as LED lamp) 10, and a thin light guide column 20 (such as figure 1 shown). Its function is only to indicate the working status. But along with increasingly fierce competition in the computer market, the appearance of the chassis has also become an important factor affecting market competition. Now major manufacturers have set their sights on the shape of each indicator light, hoping to achieve uniform illumination on a large-area light guide column. [0003] However, due to the limitation of the brightness and divergence angle of LED lights, it is very difficult to a...
