Abstract
The invention relates to an automobile instrument illumination structure which comprises a pointer cap, a pointer arm, a pointer shaft and a light guide support frame, wherein the pointer cap is sleeved outside the pointer arm, the pointer arm is connected with the light guide support frame through the pointer shaft, the illumination structure is provided with an LED (Light Emitting Diode) lamp on a PCB (Printed Circuit Board), a main reflecting surface, an auxiliary reflecting surface and a light guide post are arranged on the pointer arm, an incident light path is pointed to the main reflecting surface and the auxiliary reflecting surface by the LED lamp through the light guide post, and the reflecting light path is pointed to an instrument pointer through the main reflecting surface and the auxiliary reflecting surface; three slot holes in triangular arrangement are arranged on the main reflecting surface, and incident rays are more intensively and uniformly irradiated on the instrument pointer through the main reflecting surface and the auxiliary reflecting surface, thus the brightness of the pointer arm is uniform, and the reliability and the decoration effect of the instrument are improved.
Description
Technical field
The present invention relates to the auto meter field, relate 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 increasingly high 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 receives 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 from the pointer light source recently and by the zone of light source direct irradiation, when the pointer arm luminous componen passed the pointer cap, the brightness above the pointer cap always can be bigger than the brightness of other part of pointer arm; Thereby cause the brightness irregularities of pointer arm luminous componen, influenced and lighted whole structure that backpointer shows and attractive in appearance.
Summary of the invention
The technical issues that need to address of the present invention 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, technical scheme of the present invention is: a kind of auto meter light structures comprises pointer cap, pointer arm; Indicator needle shaft; Leaded light support, described pointer cap sleeve are outside pointer arm, and described pointer arm is connected with the leaded light support through 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, and its incident light road binders LED lamp points to main reflective surface and auxilliary reflective surface through 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 light shielding block is greater than the diameter of assembling pipe, and the assembling pipe is formed for the black light-proof material, and the leaded light post is arranged in the assembling 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 are opened the slotted eye that three triangularities are arranged on primary reflection surface, incident ray is concentrated more shine on the meter hand through 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 comprises pointer cap 1; Pointer arm 2, indicator needle shaft 6, leaded light support 3; Pcb board be arranged on the LED lamp 7 on the pcb board 4; Described pointer cap 1 is enclosed within outside the pointer arm 2, and described pointer arm 2 is connected with leaded light support 3 through indicator needle shaft 6, and described pointer arm 2 is provided with main reflective surface 9, assists reflective surface 11 and leaded light post 10; Its input path is pointed to main reflective surface 9 and auxilliary reflective surface 11 by LED lamp 7 through 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 with light shielding block 13 assembling pipe 12, and the diameter of light shielding block 13 is greater than the diameter of assembling pipe 12, and assembling pipe 12 is processed for the black light-proof material; Leaded light post 10 is arranged in the assembling pipe 12; Can prevent 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 through 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 let 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 let 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 changed incident direction through slotted eye 8 by the refraction back; 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.
