Embodiment 1
[0041] Fig. 2 is a partial sectional view showing a lamp according to a first exemplary embodiment of the present invention. It can be seen from FIG. 2 that the lamp 100 includes a lamp body 110 , a first electrode 122 and a second electrode 124 .
[0042] The lamp body 110 is in the shape of a rectangular tube. Therefore, the lamp body 110 includes first to fourth side walls 112 to 115 connected to each other, a first sealing layer 116 and a second sealing layer 117 .
[0043] The first sidewall 112 is opposite to the second sidewall 114 . The first and second sidewalls 112 and 114 have a first length L and a first width W 1 . The third side wall 113 is opposite to the fourth side wall 115 . The third and fourth sidewalls 113 and 115 have a first length L and a second width W 2 . Second width W 2 than the first width W 1 short. Fluorescent materials are coated on inner surfaces of the first to fourth side walls 112 to 115 .
[0044] The lamp body 110 includes a firs...
Embodiment 2
[0052] image 3is a partial sectional view showing a lamp according to a second exemplary embodiment of the present invention.
[0053] from image 3 It can be seen that the lamp 200 includes a lamp body 210 , a first electrode 222 and a second electrode 224 . The lamp body 210 includes first to fourth side walls 212 to 215 , a first sealing layer 216 and a second sealing layer 217 .
[0054] The first sidewall 212 is opposite to the second sidewall 214 . The first and second sidewalls 212 and 214 have a first length L and a first width W 1 . The third sidewall 213 is opposite to the fourth sidewall 215 . The third and fourth sidewalls 213 and 215 have a first length L and a second width W 2 . Second width W 2 than the first width W 1 short. Fluorescent materials are coated on inner surfaces of the first to fourth side walls 212 to 215 .
[0055] The lamp body 210 includes first and second openings 218 and 219 opposite to each other. The discharge gas 211 is inject...
Embodiment 3
[0063] Figure 4 is a partial sectional view showing a lamp according to a third exemplary embodiment of the present invention.
[0064] from Figure 4 As can be seen, lamp 300 includes a lamp body 310 and first and second electrodes 322 and 324 . The lamp of this embodiment is the same as that of Embodiment 1 except for the first and second electrodes. Therefore, the same reference numerals are used to designate the same or similar components as those in Embodiment 1, and description thereof will be omitted.
[0065] The first and second electrodes 322 and 324 include a conductive material. The first and second electrodes 322 and 324 are disposed on the outer surface of the lamp body 310 and are substantially in the shape of strip-shaped thin plates parallel to each other. The first and second electrodes 322 and 324 extend longitudinally relative to the lamp body 310 . Portions of the first and second electrodes 322 and 324 protrude from the first sealing layer 316 .
