The specific embodiment

For further setting forth technological means and the decorative effect thereof that the utility model is taked, be described in detail below in conjunction with preferred embodiment of the present utility model and accompanying drawing thereof.

Consult Fig. 1-2, the energy-efficient lamp of the utility model first embodiment comprises: lampshade 4, be located at the lamp body 2 in the lampshade 4 and be located at the ballast 5 of lampshade 4 ends; Ballast 5 electrically connects with power supply (not shown) by the pin 52 that its end is provided with, so that lamp body 2 is shinny, and, but ballast 5 stabling current also; Lampshade 4 adopts clear glass or other transparent material plastics to make, be hollow round tubular, be provided with receiving space 42 in it, be evacuated in the receiving space 42, and further be filled with argon gas and mercury vapour, and, the electrode (not shown) that electrically connects with ballast 5 be provided with in the lampshade 4, one side of lampshade 4 is made as light out part 43, is made as reflecting part 45 with respect to the opposite side of light out part 43, and reflecting part 45 is provided with reflecting layer 6.

Topmost improvements of the present utility model are, lamp body 2 is for being the lamp body 2 of non-closed, in the present embodiment, lamp body 2 is the lamp body of semicircle arcuation for cross section, can certainly be the lamp body of arbitrary circular arc shape, for example 3/4 circular-arc, 2/3 circular-arc, 1/3 circular-arc etc., circular-arc lamp body can obtain preferable light gathering; Lamp body 2 is a fluorescent lamp, be coated with phosphor powder layer 21 on it, this phosphor powder layer 21 is provided with towards reflecting part 45, in the present embodiment, lamp body 2 is positioned at the middle part of the receiving space 42 of lampshade 4, and phosphor powder layer 21 is coated with on the outer wall of being located at semi arch shape lamp body 2, and simultaneously described reflecting part 45 and phosphor powder layer 21 are located at the same side of lamp body 2, reflecting layer 6 is located on the outer wall of reflecting part 45, and reflecting layer 6 is the coating of lighttight mercury or aluminium.

As shown in Figure 3, the structure of the electricity-saving lamp of the utility model second embodiment is identical with first embodiment, and difference is that in the present embodiment described lamp body 2 ' is the linearly lamp body of cross section.

As shown in Figure 4, the structure of the electricity-saving lamp of the utility model the 3rd embodiment is identical with first embodiment, and difference is in the present embodiment, described lamp body 2 " be the lamp body of the rectangular polyline shaped of cross section, also can be the lamp body of acute angle or obtuse angle polyline shaped certainly.
