Abstract
The utility model relates to an illumination structure for an automobile instrument, which comprises a pointer cap, a pointer arm, a pointer shaft and a light guide bracket, wherein the pointer cap is sheathed outside the pointer arm; the pointer arm is connected with the light guide bracket through the pointer shaft; the illumination structure is provided with an LED (light-emitting diode) lamp on a PCB (printed circuit board); a master light reflection surface, an auxiliary light reflection surface and a light guide column are arranged on the pointer arm; an incident light path passes through the light guide column from the LED lamp to direct to the master light reflection surface and the auxiliary light reflection surface; a reflected light path directs to an instrument pointer through the master light reflection surface and the auxiliary light reflection surface; and three slotted holes arranged in a triangle way are arranged on the master light reflection surface; therefore, incident light rays can be more concentratedly and uniformly irradiated onto the instrument pointer through the master light reflection surface and the auxiliary light reflection surface, so that the brightness of the pointer arm is uniform, and the reliability as well as the decorative and attractive effects of the instrument are improved.
Description
Technical field
The utility model relates to the auto meter field, relates in particular to a kind of auto meter light structures.
Background technology
Along with the development of society, the popularizing of automobile, the utilization of up-to-date technology, people require more and more higher to the visual effect of auto meter dial plate, and the most important thing of instrument dial plate visual effect is exactly the brightness and the homogeneity of pointer on the instrument dial plate.As everyone knows, the brighter display of pointer arm, it is long more to light partial-length, just can be clear more in the time of the indication reading, visual effect also can be good more.
Because the restriction of layout, moulding, space or the like factor, the length of illumination of pointer arm always is subjected to such or such restriction, and can not be satisfactory, at this time people just expect that shinny length with pointer arm extends to and pass the pointer cap, thereby utilize the existing space layout to prolong the length of illumination of pointer arm as much as possible.But along with this newly-designed employing, new problem has just produced, that is exactly because the top of pointer cap is recently and by the zone of light source direct irradiation from the pointer light source, when the pointer arm luminous componen passes the pointer cap, the brightness of pointer cap top always can be bigger than the brightness of pointer arm other parts, thereby cause the brightness irregularities of pointer arm luminous componen, influenced and lighted whole structure that backpointer shows and attractive in appearance.
The utility model content
The utility model technical issues that need to address provide a kind of auto meter light structures makes the meter hand luminosity even to reach, and improves the purpose of instrument display effect.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of auto meter light structures comprises the pointer cap, pointer arm, indicator needle shaft, the leaded light support, described pointer cap sleeve is outside pointer arm, described pointer arm is connected with the leaded light support by indicator needle shaft, described light structures is established the LED lamp on pcb board, described pointer arm is provided with main reflective surface, auxilliary reflective surface and leaded light post, its incident light road binders LED lamp points to main reflective surface and auxilliary reflective surface by the leaded light post, and reflected light path is by main reflective surface and auxilliary reflective surface director list index.
Described leaded light post is a rectangle, imports to main reflective surface and auxilliary reflective surface after the light that the LED lamp is sent is gathered through the leaded light post.
Described indicator needle shaft is made up of assembling pipe and light shielding block, and the diameter of lucifuge piece is greater than the diameter of equipment pipe, and the assembling pipe is formed for the black light-proof material, and the leaded light post is arranged in the equipment pipe.
The described LED lamp that is arranged on the pcb board is two, and described leaded light post and LED lamp are fitted.
Described main reflective surface is a plane inclined that is arranged on meter hand one side.
Described main reflective surface is provided with three slotted eyes, and described three slotted eyes are in triangular distribution on main reflective surface.
The present invention adopts technique scheme, the leaded light post is set on pointer arm, primary reflection surface and auxilliary reflecting surface, on primary reflection surface, open the slotted eye that three triangularities are arranged, incident ray concentrated more shine on the meter hand by primary reflection surface and auxilliary reflecting surface uniformly, thereby make pointer arm brightness even, improve the reliability of instrument and the effect of beautiful decoration.

In Fig. 1-4,1, the pointer cap, 2, pointer arm, 3, the leaded light support, 4, pcb board, 6, indicator needle shaft, 7, the LED lamp, 8, slotted eye, 9, primary reflection surface, 10, the leaded light post, 11, auxilliary reflecting surface, 12, the assembling pipe, 13, light shielding block.
The specific embodiment
As shown in Figure 1, a kind of auto meter light structures, comprise pointer cap 1, pointer arm 2, indicator needle shaft 6, leaded light support 3, pcb board and the LED lamp 7 that is arranged on the pcb board 4, described pointer cap 1 is enclosed within outside the pointer arm 2, described pointer arm 2 is connected with leaded light support 3 by indicator needle shaft 6, described pointer arm 2 is provided with main reflective surface 9, auxilliary reflective surface 11 and leaded light post 10, and its input path is pointed to main reflective surface 9 and auxilliary reflective surface 11 by LED lamp 7 by leaded light post 10, and reflected light path is by main reflective surface 9 and auxilliary reflective surface 11 director list index.
Described leaded light post 10 is a rectangle, imports to main reflective surface 9 and auxilliary reflective surface 11 after the light that LED lamp 7 is sent is gathered through leaded light post 10.
Described indicator needle shaft 6 is made up of assembling pipe 12 and light shielding block 13, the diameter of lucifuge piece 13 is greater than the diameter of equipment pipe 12, assembling pipe 12 is made for the black light-proof material, leaded light post 10 is arranged in the equipment pipe 12, can prevent from not to be mapped on the meter hand, avoid the stack irradiation of many places light sources, make the light of pointer arm 2 inject environment and become complicated through the illumination of leaded light post 10 guiding, thereby be difficult to go out by structural adjustment desirable, uniform beam projecting zone.
The described LED lamp 7 that is arranged on the pcb board 4 is two, and leaded light post 10 is fitted with LED lamp 7, can allow the light of more crossing enter into leaded light post 10, has increased the degree of utilization of light.
Described main reflective surface 9 is for being arranged on a plane inclined of meter hand one side.The position from we need that we allow incident ray concentrate more is injected into the surface of pointer, increases the brightness of pointer, guarantees that brightness is even.
Described main reflective surface 9 is provided with three slotted eyes 8, and described three slotted eyes 8 are in triangular distribution on main reflective surface 9.Light is refracted the back through slotted eye 8 and changes incident direction, the part of incident ray arrives the more weak place of other light through shunt compensation, make the local brightness deterioration that incident illumination is more intense, the weak local brightness of incident illumination increases, and so just actv. guarantees the even of pointer brightness more.
