Lamp tube supporting structure

Abstract

The invention provides a support structure for lamp pipe use in back-light module. The support structure for lamp pipe comprises a bottom seat extending downwards and two suspending arms. Each suspending arm comprises an inner-arc edge and an opposite outer-arc edge, which extends upwards from the bottom seat. An accommodating space is formed. And each suspending arm has a top end so that a port is formed. A light pipe is suitable for the port and is accommodated in the space through the port. One transverse dimension of the port is less than one transverse dimension of the light pipe. Whereinto, each suspending arm has a first section and the first section has a top end region and a bottom end region. The bottom end region extends upwards from the bottom seat and the transverse section area of the first section is reduced gradually from the bottom seat to the top end region. The support structure for lamp pipe can be applied in the back-light module with large dimension to provide enough holding force for light pipe and reduce combining thrust needed in installing light pipes on the support seat correspondingly.

Description

technical field [0001] The present invention relates to a holder, in particular to a lamp tube supporting structure applied in a backlight module. Background technique [0002] In recent years, with the rapid development of flat-panel displays, the size of the flat-panel displays has gradually increased. Among them, the direct type backlight module applied to the liquid crystal display needs to increase the length of the lamp tube in order to provide sufficient brightness of the light source under the requirement of increasing the size. However, in a large-sized backlight module, an excessively long lamp tube is prone to breakage during shock or vibration testing. In order to overcome this problem, in the prior art, several lamp tube support bases are added in the middle section of the lamp tube in the backlight module, such as figure 1 As shown, to support and fix the lamp that is too long to avoid unintended breakage of the lamp. Currently in the prior art, there are va...

Problems solved by technology

However, in practical applications, the lamp tubes often jump out of the support bases due to the lack of sufficient clamping force of these lamp tube support bases, resulting in varying degrees of damage to the lamp tubes, thereby affecting the brightness provided by the light source

[0003] In view of this, in order to increase the clamping force of the lamp tube support base, there are prior technologies to increase the size of the support base to accommodate, but the result is that the combined thrust required for assembling the lamp tube on the support base is also relatively increased, increasing the lamp Combination Difficulty Between Tube and Support Seat
