Description
Technical field
The present invention relates to a kind of instrument and meter backlight, especially a kind of backlight of electric energy meter.
Background technology
In existing single-phase electric energy meter, the backlight of LCD liquid crystal is fixed on the positive sheet light guide plate of support including one, leads
LED luminescence components are housed, reflectance coating is posted at the back side of light guide plate, the edge of light guide plate surrounding posts instead in the notch of tabula rasa one end
Edge strip is penetrated with reflection light.After LED luminescence component electrified light emittings, light is by the reflection of reflectance coating and reflection edge strip, and conduction is extremely
The front of light guide plate, the front of light guide plate is lighted, shown so as to provide backlight for electric energy meter LCD liquid crystal.
As shown in fig. 6, in above-mentioned backlight, light guide plate A1 and support A2 is two independent parts, it is necessary to make respectively.
The structure of its medium-height trestle (also known as supports) A3 as shown in fig. 7, the back side of support is formed with one group of angle, and front is a plane,
The periphery of the plane is crowded around by some frame A8 forms the installation to match with light guide plate profile a reflection cavity A5, and installation is anti-
Penetrate the depth of chamber and the thickness of light guide plate matches (light guide plate sinks to and is fixed in the installation reflection cavity), the both sides of support are each
The leg that row's aperture A7 is offered for the positive LCD liquid crystal of light guide plate passes through, and wherein side is also formed with the mounting bracket of bar shaped
A4, several mounting seat A6 for being used to install electronic component are formed with mounting bracket.The structure of above-mentioned support is complex, so system
Make cumbersome, cost is also big, needs labor intensive that light guide plate is fixed on support with adhesive glue again during installation, operation is more
Cumbersome, production efficiency is not high, and there is the defects of cohesive force is strong, light guide plate and support easily disengage, influences product
Quality.
The content of the invention
The technical problems to be solved by the invention are to overcome the shortcomings of above-mentioned background technology, there is provided a kind of backlight, the back of the body
Light source have it is simple in construction, manufacture and it is easy for installation, production efficiency is high, lower-cost feature.
To realize object above, the technical solution adopted by the present invention is：
Electric energy meter integration backlight, including light guide plate, LED luminescence components are housed in the notch of light guide plate one end, it is guide-lighting
Reflectance coating is posted at the back side of plate, and the edge of light guide plate surrounding posts reflection edge strip, it is characterised in that：The front system of the light guide plate
There is one group of positioning stop, the region and size that group positioning stop surrounds match with LCD liquid crystal；The back side of light guide plate is fixed with
One group of angle, at least side edge of light guide plate are fixed with a mounting bracket, positioning stop, angle and the mounting bracket
It is integrally formed with light guide plate.
The light guide plate, angle and mounting bracket are made using transparent PC.
The mounting bracket is in bar shaped, and several mounting seats for being used to install electronic component are formed with mounting bracket；Mounting bracket with
Keep certain distance to form one between the edge of light guide plate and be beneficial to the groove that passes through of LCD liquid crystal legs, the both ends of mounting bracket with
Light guide plate is connected.
The back side of the angle and light guide plate is arranged vertically.
The quantity of the angle is four, is distributed in the corner at the back side of light guide plate.
The beneficial effects of the invention are as follows：Light guide plate, angle and mounting bracket are integrally formed by the present invention, utilize angle
The cradling function of conventional backlight is realized with mounting bracket, is led without first making light guide plate and support respectively, then with adhesive glue
Tabula rasa and the bonding work of support, overall structure is simple, and manufacture and installation steps are all simplified and facilitated, and operating efficiency obtains
Improve, cost is relatively low.

Embodiment
With reference to Figure of description, the invention will be further described, but the invention is not limited in following examples.
As Figure 1-Figure 5, electric energy meter integration backlight of the present invention, including light guide plate 1, light guide plate one end
LED luminescence components 8 are housed in notch 7.It (is four in Fig. 2, two in straight that the front of light guide plate, which is formed with one group of positioning stop 1-2,
Wire, two rectangular shapes), the rectangular area that group positioning stop surrounds matches with LCD liquid crystal, and LCD liquid crystal is fixed on this
In panel region；The back side of light guide plate is formed with site and posts reflectance coating, and the edge of light guide plate surrounding posts reflection edge strip, light guide plate
Front post black and white glue 5 (i.e. shadow shield) in one end close to notch and spilt with reducing light.The above structure of the present invention is equal
More similar with existing backlight, its assembling process does not describe in detail herein, reflects edge strip in figure and reflectance coating also gives
Omit.
In order to reduce number of assembling steps, in of the invention, the back side of the light guide plate is fixed with one group of angle 6, light guide plate
At least side edge is fixed with a mounting bracket 4, and positioning stop, angle and the mounting bracket and light guide plate use transparent PC
(makrolon) integrated injection molding.
The quantity of the angle is usually four, is distributed in the corner at the back side of light guide plate, angle and light guide plate
The back side is arranged vertically.The mounting bracket is in bar shaped, the elongated tabular of the mounting bracket, is normally at light guide plate wherein
One longer edge, substantially stretches in the same direction with light guide plate.Be formed with mounting bracket several be used for install electronic component (such as
Diode) mounting seat 2, mounting seat offers the jack 2-1 of the pin of electronic component；Between mounting bracket and the edge of light guide plate
Keep certain distance to form one to be beneficial to the groove 3 that passes through of LCD liquid crystal legs (edge of light guide plate is formed with recess 1-1, turns into
A part for groove), the leg that the groove is used for the positive LCD liquid crystal of light guide plate passes through, and the both ends of mounting bracket are by laterally stretching
The connection billet 4-1 gone out is connected with the back side of light guide plate.
