Wherein, 1, lamp housing; 2, lampshade; 3, LED; 5, three-pole switch; 6, gate controlled switch; 7, bulb rocker switch; 8, light diffusion shell end cap; 9, light diffusion shell; 10, bulb; 11, lamp housing fixing hole; 12, lampshade fixing hole; 13, end cap fixing hole.
Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the utility model is described further:
As shown in Figure 1, a kind of vehicle drive interior illuminator, comprising: lamp housing 1, is connected with lampshade 2 in described lamp housing 1, is provided with lighting circuit in described lampshade 2.
Wherein, the lamp housing 1 of the driver's cabin interior lighting device in the present embodiment there are four lamp housing fixing holes 11 and two lampshade fixing holes 12, use four thread tappings to be connected with the welding support that driver's cabin is resisted stubbornly; Lampshade 2 has two installing holes above, carries out assembly connection by the lampshade fixing hole 12 on two thread tappings and lamp housing.Lamp housing is furnished with bulb 10 and a three-pole switch 5 of a LED 3, R10W.Three-pole switch 5 is selected and is singly thrown three-pole switch, and this is singly thrown three-pole switch and is provided with " DOOR ", " OFF " and " ON " three gears.
LED 3 outside is provided with light diffusion shell 9.The light diffusion shell end cap 8 at described smooth diffusion shell 9 two ends, described smooth diffusion shell end cap 8 is fixedly connected with by end cap fixing hole 13 with lampshade 2.
Embodiment one:
As shown in Figure 2, described lighting circuit, comprise the two-way circuit be connected with external power supply, a road is connected with one end of LED 3, and the other end is connected with bulb 10; The other end of described bulb 10 is serially connected with bulb rocker switch 7, and the other end of described LED 3 is connected with the control end of three-pole switch 5; First output of three-pole switch 5 is connected to the negative pole of power supply; Second output of three-pole switch 5 is in series with gate controlled switch 6.Wherein, gate controlled switch 6 comprises a single control switch.
Generally for the security that driver uses, bulb rocker switch 7 and gate controlled switch 6 all have one end to be connected to the negative pole of external power supply; The point of contact of described LED 3 and bulb 10 is connected to the positive pole of external power supply.
The vehicle cab internal lighting device control principle of the present embodiment is:
Adopt the mode of negative control to realize the control of light, the ground strap that all gauge taps are connected on lighting loop realizes signal light control; When three-pole switch 5 closes with ground strap, light LED 3 when namely three-pole switch is positioned at " ON " position, the manual switch now as LED 3 uses; When three-pole switch is positioned at " OFF " position, cabin interior lighting device LED 3 is in closed condition, and light bar illumination is not controlled by any switch; When three-pole switch 5 closes with gate controlled switch 6 control line, when namely three-pole switch is positioned at " DOOR " position, LED 3 is controlled by gate controlled switch 6, and the gate controlled switch 6 namely opening cab door will lightening LED lamp band 3, otherwise closes LED 3.That is, LED can realize gate 6 by regulating the position of three-pole switch 5 and manual control switches control mode alternately.
