As shown in FIGS. 2 and 4, the first arcuate plate 23, the second arcuate plate 24, the first reflecting seat 25, and the second reflecting seat 26 are spaced apart from the front shade body 32 of the lampshade 3 such that the chamber 300 has an integral single space and is in communication with the opening 220.
Referring to FIGS. 3 and 4, the low beam unit 4 and the high beam unit 5 are disposed in the first and second mounting areas 250, 260, respectively. The low beam unit 4 includes a first reflecting wall 41 which is disposed in the first mounting area 250 and which faces forwardly, and a first lamp 42 which is disposed on the first reflecting wall 41. The high beam unit 5 includes a second reflecting wall 51 which is disposed in the second mounting area 260 and which faces forwardly, and a second lamp 52 which is disposed on the second reflecting wall 51. The low beam unit 4 and the high beam unit 5 are disposed in the chamber 300 such that lighting emitted from any one of the first and second lamps 42, 52 can spread over the chamber 300 and the opening 220 and a lighting range is not confined by the first reflecting seat 25 or the second reflecting seat 26. Moreover, the first reflecting wall 41 may have a curve surface to reflect light emitted from the first lamp 42 to a certain direction. Also, the first reflecting seat 25 and the first arcuate plate 23 can reflect the light so as to increase the lighting range and guide the light. Similarly, the second reflecting wall 51, the second reflecting seat 26 and the second arcuate plate 24 can reflect and guide light emitted from the second lamp 52. It is noted that light emitted from the low beam unit 4 has a smaller included angle relative to a horizontal plane than that emitted from the high beam unit 5 so that the light emitted from the high beam unit 5 has a longer radiation distance than that emitted from the low beam unit 4.
The turning lamp unit 6 includes a plurality of condensing seats 61 which are integrally formed with and extend forwardly from the base plate 21 and which are configured to define a plurality of accommodation areas 60, respectively, and a plurality of turning lamps 62 which are spaced apart from one another and which are disposed respectively in the accommodation areas 60 such that light emitted therefrom is visible through the opening 220. Light emitted from each of the turning lamps 62 is condensed by the respective condensing seat 61 to be more attractive. In this embodiment, the condensing seats 61 are arranged outwardly of the first receiving space 230 of the first arcuate plate 23 and the second receiving space 240 of the second arcuate plate 24. The turning lamps 62 are put on simultaneously to indicate a turning operation to other vehicles and passersby. The turning lamps 62 may be arranged to form together as a pointing sign, such as an arrowhead or the like.
Referring to FIG. 5 in combination with FIG. 3, a heavy duty vehicle 9 is employed with two lamp devices 2 of the embodiment. For each of the lamp devices 2 of the embodiment, light emitted from the low beam unit 4 and the high beam unit 5 can be guided and reflected by the first arcuate plate 23, the second arcuate plate 24, the first reflecting seat 25 and the second reflecting seat 26 such that the lighting range spreads over the chamber 300 and the opening 220. Thus, the light emitted from the low beam unit 4 and the high beam unit 5 is clearly visible for the coming vehicles. Light emitted from the turning lamps 62 disposed in the chamber 300 can be clearly visible for the coming vehicles.
Referring to FIG. 6 in combination with FIG. 2, for each of the lamp devices 2 of the embodiment, by virtue of the opening 220 in communication with the chamber 300 and facing laterally, light emitted from the turning lamps 62 can emit through the opening 220 so as to be visible for lateral vehicles and passerby.
As illustrated, with the chamber 300 having an integral single space and in communication with the opening 220, lighting from the low beam unit 4 and the high beam unit 5 can spread over the chamber 300 and the lighting range is not limited within the first and second mounting areas 250, 260. Moreover, the turning lamp unit 6 can emit light forwardly and laterally so as to indicate a turning operation to coming and lateral vehicles and passersby. Accordingly, additional turning lamps mounted on two sides of a vehicle are not required, which reduces a manufacturing cost of the lamp device.
While the present disclosure has been described in connection with what is considered the exemplary embodiment, it is understood that this disclosure is not limited to the disclosed embodiment but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
