Abstract

A multi-function electric bar lamp includes a cylindrical housing (1), a tubular lamp cover (2) with a thread (21) able to be combined with a thread (11) at an upper end of the housing, a cylindrical cap (5) with a thread (50) able to be combined with a thread (12) at a lower end of the housing, an LED lamp unit (3) and a battery (4) contained stably in a hollow interior of the housing (1) and the cap (5). The LED lamp is turned on and off by placing the battery (4) with the positive located up or down in the cap. Further, the housing, the cap and the lamp cover may be changed in their shape to alter the use of an electric bar lamp.

Description

BACKGROUND OF THE INVENTION

This invention relates to a multi-function electric bar lamp, particularly to one possible to be used repeatedly without polluting the environment.
Conventional lighting bars mostly use two kinds of chemicals contained separately in a plastic housing, and mixing the two kinds of chemicals to give out light by forcefully bending the plastic housing. After a conventional lighting bar is used up, it has to be discarded to make up pollution to the environment.

SUMMARY OF THE INVENTION

One purpose of the invention is to offer an electric bar lamp possible to change its use and used repeatedly.
The feature of the invention is a cylindrical housing having a hollow interior to contain an LED lamp unit and a battery therein, and the LED lamp is turned on or off by changing the direction of the battery. Further, a cap and a lamp case are changeable to change the use of the bar lamp.

DETAILED DESCRIPTION OF THE FREFERRED EMBODIMENTS

A first embodiment of a multi-function electric bar lamp in the present invention, as shown in Figs. 1, 2, 3 and 4, includes a housing 1, a lamp cover 2, an LED lamp unit, a battery 4, and a cap 5 as main components combined together.
The housing 1 is cylindrical, having a hollow interior 10, female threaded 11 formed in an upper end and male threads 12 formed in a lower end.
The lamp cover 2 is tubular, having male threads 21 in a lower end to engage with the female threads 11 of the housing 1 and a plurality of straight cut lines 20 spaced apart around an outer surface for increasing brightness of the LED lamp 3. Further, a ring 22 is fitted around the male threads 21 to prevent water from simmering in the housing 1 after the lamp cover 2 is combined with the housing 1.
The LED lamp unit 3 is fixed in the hollow interior of the housing 1, having a circuit board 30 fixed on a cylindrical base 31, two pins 32, 33 extending down from the circuit board 30 so as to respectively contact with a positive 40, and a negative 41 of the battery 4 to light up the LED lamp as shown in Fig. 3.
A cap 5 is cylindrical, having female threads 50 in an upper end to engage with the male threads 12 of the housing 1 and a vertical hole 51 formed in the center of a bottom of the cap 5 for the positive 40 of the battery 4 to fit therein for turning on the lamp and to turn off the lamp when the battery 4 is placed upside down as shown in Fig. 4. The battery 4 may not be swayed around to produce noise, fixed steady whether the battery 4 is placed with the positive 40 located up or down.
Figure 5 shows a second embodiment of a multi-function electric bar lamp in the invention, having almost the same structure as the first embodiment, except a crystal ball 23 added on the lamp cover 2A. The second embodiment may be used for occasions of glamorous activities.
Figure 6 shows a third embodiment of a multi-function electric bar lamp, having also almost the same structure as the first embodiment, except an elongate lamp cover 2B instead of the lamp cover 2 in the first embodiment, usable for occasions of glamorous activities, too.
Figures 7 and 8 show a fourth embodiment of a multi-function electric bar lamp, having the same structure, except the lamp cover 2C provided with an annular inner recess 2C0 and a light cap 2C1 made of semi-transparent material fitted in the annular inner recess 2C0. Then this bar lamp can be fixed with a sight section A0 of a gun (A) for shooting at night.
Figures 9 and 10 show a fifth embodiment of a multi-function electric bar lamp, having the same structure as the first embodiment, except the cap 5A provided with a ball member with a lateral through hole 5A0. Then the fifth embodiment may be hung on a ring article such as a key holding ring, a hanging embellishment, a necklace, etc.
Further, Figures 11, 12, and 13 are modified from the fifth embodiment, forming respectively a sixth, a seventh and an eighth embodiment of a multi-function electric bar lamp. The sixth embodiment has a housing 1, a cap 5B and a lamp cover 2C changed in their shape into a float, for fish to gather. The seventh shown in Fig. 12 has a float E with a center vertical hole E1 for the bar lamp inserted therein so as to form a queer shaped float for fish to come and gather around. The eighth embodiment shown in Fig. 13 has a lamp cover 2D provided with a fishhook 2D0 contained in an artificial fly (B) for fishing so as to lure fish with light.
Lastly Fig. 14 shows a ninth embodiment having a housing 1B with a cap formed integral. Fig. 15 shows an LED unit having a plurality of LED lamps fixed on the circuit board for increasing brightness or changing the colors of the LED lamps. Further, the LED lamps may be lit always or flickeringly.
While the preferred embodiments of the invention have been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications that may fall within the spirit and scope of the invention.
