Embodiment Construction

[0013] Such as figure 1 As shown, an arc-shaped grille lamp adopting cold-cathode lamp tubes includes a lamp chassis 1, a lamp head 5 and an arc-shaped grille 4, and the cold-cathode lamp tubes 3 are fixed on the reflector of the lamp chassis 1 through tube clamps 6. , the terminals of the inverter 7 are connected to the electrodes of the cold cathode lamp tube 3.

[0014] figure 1 The cold-cathode lamp tube 3 in the embodiment adopts double U-shaped cold-cathode lamp tubes.

[0015] When the present invention is assembled, the reflector is fixed on the lamp chassis 1 through the tube clips 6, and the tube clips 6 are made of plastic, and six are fixed on the reflector side by side. After the end of the tube clamp 6 passes through the hole of the reflector and the opening of the lamp chassis 1, the end is fixed by a nut. Two U-shaped cold cathode lamp tubes 3 are fixed side by side on the tube clamp 6 . The inverter 7 is fixed on one side of the lamp chassis 1, the electro...

Abstract

The invention relates to a cambered grille lamp with a cold cathode tube, belonging to a lighting light fitting and comprising a light fitting chassis, a light fitting holder and a cambered grille. A cold cathode tube is fixed on a light reflecting plate of the light fitting chassis by a pipe clamp; and the wire connecting terminal of an inverter is connected with the electrode of the cold cathode tube. A U-type tube is adopted as the cold cathode tube. The double-U-type cold cathode tube is adopted as the tube, the service life of the cambered grille lamp can reach more than 60,000 hours; the cambered grille lamp can be frequently switched for not less than 1 million times; the power dissipation is small, the light decay is small and the tube wall temperature is low, thereby effectively reducing the heat loss caused by heating. The double-U-type cold cathode tube is cooperated with a one-to-two inverter to drive with double high voltages, thus the light-up parameters of the tube are more stable. The input voltage of the inverter is 220 V; compared with the traditional DC input inverters, the inverter does not need to transfer voltage, thereby facilitating family and office use.

Description

technical field [0001] The invention relates to a lighting fixture, in particular to an arc-shaped grille lamp using a cold cathode lamp tube as a light source. Background technique [0002] Traditional arc grille lamps mainly use T5 or T8 fluorescent lamps, which have disadvantages such as high power consumption, short life, fast light decay, and few startup times. Contents of the invention [0003] The object of the present invention is to provide an arc-shaped grille lamp with a cold cathode lamp tube, which has long service life, energy saving and good color rendering. [0004] The object of the present invention is achieved in this way: an arc-shaped grille lamp adopting a cold cathode lamp tube, including a lamp chassis, a lamp head and an arc-shaped grille, and the cold cathode lamp tube is fixed on the reflector plate of the lamp chassis through a tube clamp , the terminals of the inverter are connected to the electrodes of the cold cathode lamp tube. Cold cathod...
