Abstract
An instrument meter panel capable of enhancing indicating light source visibility is disclosed. The instrument meter panel capable of enhancing indicating light source visibility comprises an instrument meter plate, pasting sheet type LEDs, and a PCB circuit board, wherein the pasting sheet type LEDs are mounted on the PCB circuit board, the instrument meter plate is made of transparent engineering plastics and is connected onto the PCB circuit board, the lower part of the instrument meter plate is provided with a light guide part which extends downward, the lower surface of the light guide part is close to the pasting type sheet LEDs, the upper surface of the instrument meter plate is provided with a display part which corresponds to the light guide part, and the display part is provided with a protruding face which bulges upward. The instrument meter panel capable of enhancing indicating light source visibility is characterized by compact whole structure, increased visible area of the display part, improved omnibearing visual effects, increased indicating light source visibility, and suitability for a place having relatively small installation space.
Description
Technical field
The utility model relates to a kind of structure of instrument and meter dish, is specifically related to a kind of instrument and meter dish that strengthens indication light source visibility.
Background technology
One of major function of instrument and meter dish is made real-time demonstration to the operational factor of place device or system exactly, in order to allow operating personnel in time understand the operation conditions of this device or system, and then takes to control measure.As the display element of instrument and meter dish, the LED lamp is widely used as the indication light source into instrument and meter.
At present, the LED lamp can roughly be divided into pinned and SMD according to its structure.The advantage of pinned LED is that luminous quantity is bigger, is easy to light source is delivered to the surface of instrument and meter dish, and the visibility of light is also more intense, thereby clear display, observation are convenient; And that the advantage of adopting surface mounted LED is structural volume is little, and required installing space is also few, can be widely used in the instrument and meter dish of compact conformation.But they also exist shortcoming separately:
1. the volume ratio of pinned LED structure is bigger, therefore needs relatively large installing space, and this occasion in some structural requirement compactness will be restricted in the use.
2. the volume of adopting surface mounted LED has significantly compared with pinned LED and reduces, and is more weak but its shortcoming is luminous intensity, and the below that must be close to instrument instrument dish could be delivered to light source the instrument and meter panel surface with short as far as possible distance; But when adopting surface mounted LED and instrument and meter panel surface distance was far away, the light source that then is delivered to the instrument and meter panel surface was just weakened significantly, the visual effect variation, and particularly when viewing angle for inclination the time, it is clear that naked eyes are difficult to distinguish.
The utility model content
The purpose of this utility model is the deficiency at above-mentioned prior art existence, a kind of instrument and meter dish that strengthens indication light source visibility is provided, it adopts adopting surface mounted LED as the indication light source, but when being the oblique angle at remote or visual angle, still can clearly observe demonstration.
The utility model is achieved through the following technical solutions:
A kind of instrument and meter dish that strengthens indication light source visibility, include gauge dial, adopting surface mounted LED and PCB circuit board, described adopting surface mounted LED is installed on the described PCB circuit board, described gauge dial is made by transparent engineering plastics, it is connected on this PCB circuit board, the bottom of this gauge dial is provided with the light guide section of downward extension, the lower surface of this light guide section is near described adopting surface mounted LED, the upper surface of described gauge dial is provided with the position display part corresponding with this light guide section, and this display part has the convex surface to upper process.
The lower surface of described light guide section is concave.
Described gauge dial is provided with lighttight coating except the lower surface of light guide section and other surface the display part.
The convex surface of described display part is arc or trapezoidal.
Compared with prior art, advantage of the present utility model is:
1, adopt adopting surface mounted LED as the indication light source, compact overall structure adapts to the less relatively occasion of installing space.
2, the surface is provided with the display part of convex-shaped, can make light source to around emission, increased effective area, thereby when reaching the visual angle and being the oblique angle, observer's naked eyes also can distinguish clear easily, have improved omnibearing visual effect.
3, described instrument and meter dish is provided with the light guide section near adopting surface mounted LED, the light of adopting surface mounted LED can be conducted to the display part of instrument and meter panel surface and does not weaken, and has reached the effect that increases visibility.

Embodiment
Below in conjunction with drawings and Examples the utility model is elaborated, but protection domain of the present utility model is not limited to following embodiment.
See also the structural drawing of Fig. 1, Fig. 2 and the utility model embodiment one shown in Figure 3, the instrument and meter dish of described enhancing indication light source visibility includes gauge dial 1, adopting surface mounted LED 2 and PCB circuit board 3.Described adopting surface mounted LED 2 is provided with several for the indication light source, is installed on the described PCB circuit board 3.Described gauge dial 1 is formed by transparent engineering plastics processing and forming, and it is connected on this PCB circuit board 3; The bottom of this gauge dial 1 is provided with the light guide section 11 of downward extension, the lower surface 13 of this light guide section 11 is concave, play the effect of concavees lens, it is near described adopting surface mounted LED 2, so that with the upper surface of the indication light source guide instrument device dial plate 1 of this adopting surface mounted LED 2; The upper surface of described gauge dial 1 is provided with the corresponding display part 12 of position and this light guide section 11, this display part has the convex surface to upper process, in the present embodiment, the convex surface of this display part 12 is arc, it has played the effect that increases effective area, can make light source to emission all around, thereby improve omnibearing visual effect, when even the visual angle is the oblique angle, observer's naked eyes also can distinguish clear easily; Described gauge dial 1 is coated with lighttight coating on the lower surface 13 of light guide section 11 and other surface the display part 12.
See also the structural drawing of Fig. 4 and the utility model embodiment two shown in Figure 5 again, the structure of embodiment two is basic identical with embodiment one, and difference is that the convex surface of described display part 12 is trapezoidal, and its effect is identical with embodiment one.
Every all equivalence of doing according to the utility model spirit changes or equivalence is replaced, and all should be included in the scope that the claim of the utility model patented claim contains.
