Abstract

The invention discloses an on-line tester of a phosphor powder tube. The existing phosphor powder tube excitation device is difficult to ensure the accuracy of the on-line test of the phosphor powder tube. The on-line tester of the phosphor powder tube is characterized in that an ultraviolet lamp tube controlled by a switch, a lamp tube clamp which can adjust the position and corresponds to the ultraviolet lamp tube, and a light color detector are arranged on a seat body, and the light color detector is connected with a data processing instrument; the light beam inlet of the light color detector is provided with a light transmission piece capable of preventing dust from entering the light color detector, and the surface of the whole tester is black so as to prevent the interference causedby reflection. The invention can effectively ensure the accuracy of the online test of the phosphor powder tube, and provides a practical equipment technology guarantee for the online test of the tester.

Description

technical field [0001] The invention belongs to a photoelectric detection device, in particular to an online tester for fluorescent powder tubes, which is used for process detection of light and color parameters of semi-finished lamp tubes (ie fluorescent powder tubes) during the production process of fluorescent tubes. Background technique [0002] With the development of green lighting and technological progress, the development and application of rare earth luminescent materials and the expansion of energy-saving technology, nowadays, whether it is a thin-tube straight tube fluorescent lamp, a thin-tube ring tube fluorescent lamp, or a compact fluorescent lamp, in addition to pursuing high luminous efficiency and high display More and more attention is paid to the requirements of color coordinates, color tolerance and color temperature. The most common problems raised by customers in the production of fluorescent lamps are color temperature consistency, energy-saving fluo...
