Embodiment Construction

[0011] The present invention is specifically described below in conjunction with specific embodiment and accompanying drawing:

[0012] refer to figure 1 As shown, a CCFL light bulb with an open mouth includes a lampshade 2, a CCFL lamp tube 3, and a lamp base 1. The lamp base 1 is provided with a lampshade 2 for guiding light rays, and the lampshade 2 is open. The lamp base 1 is integrally formed with the lampshade 2 . The advantage of this technical solution is: the open lampshade is set, which can guide the invalid light refracted to the rear at the base of the CCFL bulb lamp to the front, improving the light illumination in the front; and when installing, hold the lampshade to install, avoiding The disadvantage of holding the lamp tube to install is easy to be damaged and fragile. Since the lampshade is open, it also increases the area for heat dissipation, which is beneficial to the heat dissipation of the bulb, and improves the problem of heat dissipation that leads to ...

Abstract

The invention discloses a CCFL bulb with an open lampshade. The CCFL bulb with the open lampshade comprises the lampshade, a CCFL lamp tube and a lamp base, wherein the lamp base is provided with the lampshade which is used for guiding the radiation direction of light; the lampshade is open; the lamp base and the lampshade form a whole body; the lampshade is arranged on the lighting basal-most part of the CCFL lamp tube; the lampshade is of an arc cup shape which expands from inside to outside from the lamp base; the lampshade is made of metal; and the lampshade is an aluminum lampshade. Compared with the prior art, the CCFL bulb with the open lampshade has the advantages that the CCFL bulb with the open lampshade is more energy-saving; light illuminance is higher; assembly is more convenient and safe; the heat dissipation property of the lamp tube is better; and the service life of the CCFL bulb is longer.

Description

technical field [0001] The invention relates to the field of lighting fixtures, in particular to a CCFL light bulb with an open cover. Background technique [0002] At present, the CCFL bulbs developed on the market generally have a tube diameter of about ψ4 (ψ3, ψ5). Due to the thin tube diameter and insufficient rigidity, the tube is directly held and screwed into the lamp holder to fix it, and it is easy to touch when installing. Accidental contact breakage can easily cause injury. Therefore, some existing CCFL bulbs are equipped with glass covers and plastic covers to protect the CCFL tubes, making it easier and safer to replace CCFL bulbs. However, CCFL bulbs with glass covers are not easy to dissipate heat, which will easily reduce the life of the power board, increase the chance of damage, and also reduce the illuminance of the light; CCFL bulbs with plastic covers are easy to heat when the plastic is heated. Deterioration will cause plastic deterioration and discol...
