Description

LED lamp tube with reflection shield

Technical field

This utility model relates to a kind of light source, the LED lamp tube of a kind of band reflection shield.

Background technology

LED lamp tube is big with its brightness, energy consumption is low, the advantage of length in service life, the most progressively start to substitute traditional fluorescent tube, simultaneously, along with the use development of demand, the technological progress of LED lamp tube self and the design requirement of each manufacturer of user, the structure of LED lamp tube also creates various different change.The basic structure of LED lamp tube is a light-transmitting tube body and the lamp holder being located at light-transmitting tube body two ends, the LED metal basal board electrically connected with lamp holder it is provided with in light-transmitting tube body, metal basal board is provided with LED lamp bead, LED metal basal board is also associated with driving power supply, power supply is driven to be generally arranged in lamp holder or fluorescent tube, can also be external, be not provided with in LED lamp tube.

Owing to the luminous characteristics of single led lamp bead is that single-point is luminous, in order to obtain the softest illumination effect, need to make light-transmitting tube body present a kind of printing opacity but opaque effect, the light sending LED lamp bead is scattered, thus obtain soft light, otherwise can produce discontinuous dazzling hot spot, based on this purpose, different manufacturers have employed different modes and realizes, such as:

1, first process transparent body, then body is carried out frosted process, form frosted printing opacity but opaque effect；

2, first processing transparent body, then inwall or outer wall to body are coated processing so that it is form printing opacity but opaque effect；

3, the transparent tube body being close to outer layer is socketed a printing opacity but opaque body, forms a kind of printing opacity but opaque effect；

4, this type of outer layer fluorescent tube is printing opacity but during opaque state, and the luminescence of pipe is understood some and dissipated to fluorescent tube both sides, in order to carry out optically focused during use, improves light efficiency, needs by outside lampshade.

Above-mentioned first two mode is required to increase the manufacturing procedure of parts, need to expend when producing in enormous quantities and substantial amounts of manually complete with the time, affect working (machining) efficiency, and the third mode is owing to being directly socketed near transparent tube body inwall by printing opacity but opaque body, so printing opacity but the internal diameter of opaque body is the most relatively large, need when internally installed LED metal basal board to use extra parts or structure that LED metal basal board is fixed support, also need to carry out light tight process at the back of LED metal basal board simultaneously, and the 4th kind of structure needs to carry out optically focused by outside lampshade, certain requirement is proposed to installing, reduce the versatility of product.
