(first embodiment)
Fig. 2 A is the sectional perspective schematic diagram of light-source structure 1 of the expression first embodiment of the present invention, and Fig. 2 B is the exploded perspective schematic diagram of a plurality of bending channels 61,62 that shows the light-source structure 1 of first embodiment of the invention.Fig. 2 C is the generalized section of the light-source structure 1 observed of the BB ' hatching of expression in Fig. 2 A.It should be noted that only indicate two bending channels 61,62 on Fig. 2 B and be example, the present invention does not limit the quantity and the length of bending channel.
In the present embodiment, shown in Fig. 2 A and 2B, light-source structure 1 is positioned on the XY plane, and light-source structure 1 is formed by a hollow housing 20, positive and negative electrode and a plurality of protuberance 50.Because for simplicity of illustration, Fig. 2 A only shows an electrode E wherein, to omit the electrode that is positioned at housing 20 other ends is shown, the length of the discharge path 6 between the two end electrodes then is to be determined by the length of the bending channel 61,62 in the housing 20.
Shown in Fig. 2 C, the protuberance 50 of light-source structure 1 comprises a plurality of first protuberances 51 and a plurality of second protuberances 52.First protuberance 51 is arranged at first plate, 21, the second protuberances 52 and is arranged at second plate 22, and second protuberance 52 is outstanding towards the direction of first plate 21, and first protuberance 51 and second protuberance 52 are crisscross arranged, and form bending channel 61 or 62.That the shape of protuberance 50 can be is trapezoidal, taper shape or arc.It should be noted that the present invention is not limited to the shape of above-mentioned protuberance 50.Because bending channel 61 or 62 is formed by protuberance 50,40 of how extra fluorescent materials can be arranged on the protuberance 50 (inwall of bending channel), not only the contact area of plasma and fluorescent material increases, each bending channel 61 or 62 that extends along the XZ plane can increase the discharge path 6 of electrode E, and then strengthens the luminous efficiency of light-source structure 1.
The following manufacture method of crooked channel of the light-source structure 1 of explanation first embodiment.
Utilize the die sinking design to protrude in first protuberance 51 and second protuberance 52 that protrudes in second plate 22 of first plate 21, with cold welding or crimping mode with first plate 21 and second plate, 22 affixed being integral, first protuberance 51 and second protuberance 52 and then formation bending channel 61,62 are crisscross arranged.
Therefore, the light-source structure of present embodiment has laterally bending channel arranged side by side, can increase the contact area of plasma and fluorescent material, prolongs discharge path simultaneously, to reach the increase of luminous efficiency and brightness.
(second embodiment)
Fig. 3 A is the schematic perspective view of the light-source structure 2 of expression second embodiment.Fig. 3 B is the floor map that shows the light-source structure 2 of second embodiment.Fig. 3 C is the generalized section that demonstration is observed along the CC ' hatching among Fig. 3 A.The light-source structure 2 of second embodiment is formed by a hollow housing 200, plus or minus electrode E and a plurality of protuberance 500.Housing 200 comprises a plurality of bending channels 610, one first plate 210, one second plate 220, a first side wall 230, one second sidewall 240 and a plurality of dividing plate 300, and fluorescent material 400 is arranged at the inwall of bending channel 610.Protuberance 500 comprises a plurality of first protuberances 510 and second protuberance 520.In the present embodiment, the part identical with first embodiment will repeat no more, and its difference is: first protuberance 510 is hollow, to hollow out or the mode of etching first plate 21 and form the inner space 71 of first protuberance 510, inner space 71 is connected with the space outerpace of housing 20, shown in 3A and 3C figure.Same, second protuberance 520 is a hollow, and to hollow out or the mode of etching second plate 22 and form the inner space 72 of second protuberance 520, inner space 72 is connected with the space outerpace of housing 20.
Therefore, when looking down angle and observe, again referring to Fig. 3 B, the upper surface of first plate 210 has a plurality of grooves 71 ' of vertical arrangement (arranging along X-direction), each groove 71 ' extends along Y direction, that is the bearing of trend of groove 71 ' is perpendicular to the bearing of trend of bending channel 610,620, formed and groove 71 ' is inner space 71 by first protuberance 510 of hollow.In addition, though second plate 220 is not shown among the figure, the upper surface of second plate 220 has a plurality of grooves equally.
The following manufacture method of crooked channel 610,620 of the light-source structure 2 of explanation second embodiment.
Simultaneously, hollow out the inner space 71 that first plate 210 forms first protuberance 510 by etching or alternate manner referring to 3B and 3C figure, that is, form a plurality of grooves 71 ' at the upper surface of first plate 21, make first protuberance 510 become hollow.Same, form the inner space 72 of second protuberance 520 in the mode of etching second plate 22, that is, form a plurality of groove (not shown)s at the upper surface of second plate 220, make second protuberance 520 become hollow.
In sum, because light-source structure of the present invention can increase the contact area of plasma and fluorescent material, prolong discharge path 60 simultaneously, to reach the increase of luminous efficiency and brightness.
Though the present invention discloses as above with preferred embodiment; yet it is not in order to limit the present invention; any those skilled in the art; without departing from the spirit and scope of the present invention; certainly can do some and change and retouching, so protection scope of the present invention should being as the criterion with scope institute circle of claims.
