The specific embodiment
Need to prove that under the situation of not conflicting, embodiment and the feature among the embodiment among the application can make up mutually.Describe the utility model below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
As shown in Figure 1, the utility model provides a kind of lighting device, provides illumination to illuminated portion.This lighting device comprises light source portion 20 and light guide section 30.Light guide section 30 is Transparent Parts and curved and have an into light portion 31.Light guide section 30 is curved, helps the reflection and the propagation of light, and light guide section 30 is for Transparent Parts is beneficial to printing opacity, the light guide section 30 illuminated portion of the light that light source portion 20 is sent can being led.
The light source portion 20 of this lighting device is arranged on into light portion 31 places, the light guide section 30 illuminated portion of the light that light source portion 20 is sent can being led.Light is after enter light portion 31 and enter light guide section 30, and light is constantly reflection in whole light guide section 30, so just propagation in whole light guide section 30 of light.Like this, the transparent light guide section 30 illuminated portion of just light that light source portion 20 is sent can being led.Lighting device only need be provided with a spot of light source portion 20 and enough light is provided just can for illuminated portion.Thereby lighting device of the present utility model can reduce the structure that the quantity that light source portion is set has been simplified lighting device, has reduced cost.
As depicted in figs. 1 and 2, light guide section 30 is for having the leaded light ring of notch part 32, and the two ends of light guide section 30 extend to notch part 32 places, and the end, two ends forms into light portion 31, and entering light portion 31 is two.Wherein, the shape of leaded light ring is more conducive to the propagation of light.The effect of notch part 32 is, can enter light portion 31 so that light guide section 30 forms two with this.Preferably, the two ends of light guide section 30 are bent to form into light portion 31 to light source portion 20, and the setting of so also both being convenient to light source portion 20 also is convenient to light source portion 20 and is more pressed close to into light portion 31.Light portion 31 makes full use of and guides light source portion 20 in order to allow into, the quantity of light source portion 20 is consistent with the quantity of entering light portion 31, so each advance light portion 31 below be provided with light source portion 20, light enters light portion 31 from two and enters the light guide section 30, because light guide section 30 is that light enters light portion 31 from two and enters the leaded light ring for the leaded light ring, light is constantly reflecting to propagate in the leaded light ring and is advancing, final light converges at the middle part of whole leaded light ring, the middle part of leaded light ring is away from notch part 32, and promptly the middle part of leaded light ring is away from entering light portion 31.
From advancing the light that light portion 31 enters light guide section 30, wherein a part of light reflects away from light guide section 30, and another part light is propagated in light guide section 30.Because the propagation of light in light guide section 30 has loss, so the some areas in the light guide section 30 particularly will be very weak in the propagation away from the local light that enters light portion 31.In order to address this problem, as depicted in figs. 1 and 2, preferably, the surface of light guide section 30 is provided with zigzag reflecting part 33.Because reflecting part 33 is a zigzag, zigzag is beneficial to the reflection of light, can be good at the propagation of auxiliary light, makes light to propagate into away from the place of entering light portion 31 in light guide section 30, has guaranteed that light can be transmitted to whole light guide section 30.Light guide section 30 be arranged on illuminated portion near, illuminated like this just can be shone by light by light guide section 30.
As shown in Figure 2, reflecting part 33 relatively is provided with notch part 32, and reflecting part 33 is away from entering light portion 31.The middle part of whole light guide section 30 is that light is propagated the most weak place, so reflecting part 33 need be set at this position.Preferably, the angle of the central shaft of the two ends of reflecting part 33 and light guide section 30 is α, wherein, and 60 °≤α≤90 °.
As shown in figures 1 and 3, the reflecting part 33 of light guide section 30 is the zigzag of a plurality of continuous grooves, and reflecting part 33 can be arranged on the outer surface or inner surface of light guide section 30.Reflecting part 33 can only be arranged on the outer surface of light guide section 30, preferably, can be arranged on the upper surface or the lower surface of light guide section 30.If illuminated portion is arranged on the below of light guide section 30, then reflecting part 33 can only be arranged on the upper surface of light guide section 30, and promptly light is towards the reflection of the below of light guide section 30, and light can be directed to the illuminated portion of light guide section 30 belows.Same principle, if illuminated portion is arranged on the top of light guide section 30, then reflecting part 33 can only be arranged on the lower surface of light guide section 30, and promptly light is towards the reflection of the top of light guide section 30, and light can be directed to the illuminated portion of light guide section 30 tops.
As shown in Figure 1, lighting device also comprises connecting portion 40.Connecting portion 40 is arranged on the light guide section 30, and light guide section 30 is connected with the support that is used to support illuminated portion by connecting portion 40.Preferably, connecting portion 40 is a buckle.
In the foregoing description, Transparent Parts, the printing opacity of acrylic and the better performances of propagating light that light guide section 30 can be made by acrylic material.Light guide section 30 is a Transparent Parts, is beneficial to printing opacity, the light guide section 30 illuminated portion of the light that light source portion 20 is sent can being led.
The utility model also provides a kind of vehicular meter, as shown in Figure 1, comprise instrument board, provide the lighting device of illumination and the printed circuit board 10 that is electrically connected with lighting device for instrument board, lighting device is aforesaid lighting device, lighting device is arranged on the top of printed circuit board 10, and the light guide section 30 of lighting device is with light guide instrument dial plate.Wherein, instrument board can be arranged on the top of lighting device.
As can be seen from the above description, the utility model the above embodiments have realized following technique effect:
1, the lighting device of light guide section only need be provided with a spot of light source portion and just can provide enough light to illuminated portion;
Thereby 2, reduced cost owing to reduce the quantity that is provided with light source portion.
The above is a preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
