Title: Anti-slip fluorescent electronic energy-saving lamp

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a lighting apparatus, and more particularly, to a fluorescent electronic energy-saving lamp. 
     2. Description of Related Art 
     The fluorescent electronic energy-saving lamp is a kind of lighting apparatus which has a fluorescent tube or bulb as the luminous body. It is popular in the home and abroad in virtue of its many advantages such as saving energy and environment protection. The conventional fluorescent electronic energy-saving lamp comprises a fluorescent tube and a lamp cabinet in which are located electronic parts. It may further comprise a lamp base which functions to protect the lamp cabinet, and a glass cover or a lamp shade which functions to protect the fluorescent tube. Traditionally, the lamp tube is made of glass, and the lamp cabinet is made of metal. Since both of these materials are slippery, the conventional fluorescent electronic energy-saving lamp easily falls to the ground and break into pieces when one tries to grasp it in hand. Furthermore, the appearance of the lamp in the prior art is monotonic in color, it is either grey or white, looks awkward and dull. 
     SUMMARY OF THE INVENTION 
     The aim of this invention is to overcome the shortcomings of the prior art mentioned above, and provide an anti-slip fluorescent electronic energy-saving lamp which is easy to grasp in the hand tightly. The anti-slip fluorescent electronic energy-saving lamp of the present invention comprises a fluorescent tube and a lamp cabinet within which the electronic parts are installed. The outer shell of the lamp cabinet has a surface of revolution, on which an anti-slip ring is mounted. The anti-slip ring is made of anti-slip materials and the ring sectional plane of the anti-slip ring is in parallel with the circular sectional plane of the outer shell of the lamp cabinet. 
     Another aim of this invention is to provide a fluorescent electronic energy-saving lamp which has a colorful appearance. 
     In a preferred embodiment of the present invention, the anti-slip ring is made of rubber or plastic. 
     Due to the anti-slip ring being mounted outside the outer shell of the lamp cabinet, the fluorescent electronic energy-saving lamp of the present invention is easy to grasp and will not easily fall to the ground and break into pieces during installation and usage. Since the anti-slip ring is made of rubber or plastic, it can be made into various colors which is helpful for identification and decoration.

     DETAILED DESCRIPTION OF SPECIFIC EMBODIMENTS 
     The description above and below and the drawings of the present document discuss one or more currently preferred embodiment(s) and also describe some exemplary optional feature(s) and alternative embodiment(s). The description and drawings are for the purpose of illustration and not limitation. Section titles are terse and are for convenience and not limitation. 
     Referring to FIGS. 1,  2  and  3 , in one preferred embodiment of the present invention, the anti-slip fluorescent electronic energy-saving lamp comprises a glass cover  101 ; a fluorescent tube or bulb  102 ; tube holder  104 : anti-slip ring  105 ; electronic parts  106 ; a lamp cabinet having a top lamp cabinet  103  and a bottom lamp cabinet  103 ′; and a lamp bottom  107 . The electronic parts  106  are installed inside the bottom lamp cabinet  103 ′, the tube  102  is fixed by the tube holder  104 , and the tube  102  is electrically connected with the electronic parts  106 . On the bottom of the tube holder  104  there are internal screws, matching with the external screws on the top of the bottom lamp cabinet  103 ′, and the tube holder  104  and the bottom lamp cabinet  103 ′ are joined together through the screws. On the tube holder  104  there are external screws, matching with the internal screws on the bottom of the top lamp cabinet  103 , and the tube holder  104  and the top lamp cabinet  103  are joined together through the screws. The anti-slip ring  105  is ring-shaped, and on the top lamp cabinet  103  there is a groove for receiving the anti-slip ring  105 . 
     As shown in FIG. 4, the bottom end  1051  of the anti-slip ring  105  is protruding inwards and blocked within the groove of the top lamp cabinet  103 , so as to make the outer surface plain. The anti-slip ring  105  is made of anti-slip material, such as rubber or plastic, etc. The glass cover  101  is mounted on the top lamp cabinet  103  to protect the fluorescent tube  102 . Since the anti-slip ring  105  is made of rubber or plastic, it can be held firmly in hand, and the lamp will not easily fall to the ground and break into pieces in installation and usage. In addition, the anti-slip ring can be made into various colors, and have decorative effects. 
     Referring to FIGS. 5 and 6, in another preferred embodiment of the present invention, there is no glass cover outside the lamp tube  102 , and the lamp cabinet is an integrated entity, on which there is a groove to receive the anti-slip ring. The anti-slip ring is tube-shaped, and installed inside the groove on the lamp cabinet. On the lamp cabinet, there is installed a lamp shade  201 , which has a base on its top, matching with the lamp cabinet. The lamp shade  201  is mounted outside the anti-slip ring, to avoid damage to the lamp cabinet due to the direct contact with the lamp cabinet. Since the frictional coefficient of the anti-slip ring is relatively bigger, a relatively bigger silent frictional force will generate between the anti-slip ring and the lamp shade  201 , so as to help the lamp shade  201  be firmly fixed on the lamp cabinet. In this embodiment, an anti-slip ring of specific color is used for an energy-saving lamp of a different power, therefore, the anti-slip ring can also be useful for identifying different products embodying the invention. 
     The scope of the invention is not limited merely to the specific example embodiments or configurations of the foregoing description, but rather is indicated by the appended claims. All changes that come within the meaning and range of equivalents within the claims are intended to be understood as being embraced within the scope of the claims.
