Description

Energy saving luminous direction board

Technical field

It the utility model is related to a kind of energy saving luminous direction board, including the light emitting directory board used main body made by light guide plate, LED Luminescence chip, aluminium direction board protecting border.

Background technology

Light emitting directory board used application is quite varied, and most of indoor and outdoor is light emitting directory board used at present, and majority is added using fluorescent tube The pattern of lamp box, textures text is printed on lamp box, in a manner of built-in lamp luminescence irradiates drawing, this mode power consumption is very Height, and the life-span do not grow, volume is larger.

The light emitting directory board used dot matrix layout using LED display in part, which makes, forms luminous picture and text, energization lightening LED lamp pearl Formed it is luminous, this pattern it is light emitting directory board used expensive, and it is relatively difficult to install maintenance.

Utility model content

In view of the above-mentioned problems, the technical problems to be solved in the utility model be to provide it is a kind of light emitting directory board used, including by The light emitting directory board used main body that light guide plate is made, LED luminescence chips, aluminium direction board protecting border.Its operation principle is mainly profit The light guide plate made certainly with optical grade acryl plates draws the stop from the light that lamp issues on optical grade acryl plates surface, And silk-screen light guiding points make character pattern on light guide plate, when light is mapped to each light guiding points, by close Jie of light in light guide plate The light of matter reflection can spread toward all angles, then be projected from the light guiding points for destroying conditioned reflex.

Of the present utility model light emitting directory board used, in the method that the front of rectangle light guide plate uses laser silk-screen, printing is led Luminous point forms required pictograph, and uniformly miniature LED luminescence chips are installed respectively apart from upper in light guide plate surrounding each edge, Connected between each miniature LED luminescence chips with parallel way.LED luminescence chips are lighted, the light sent is penetrated from light guide plate side Enter inside light guide plate, run into the close dieletric reflection of light guide plate interior lights, run into after the light guiding points printed on light guide plate from guide-lighting fixed fire Go out to be formed luminous pattern word.

It is of the present utility model light emitting directory board used, it is outer on light guide plate add aluminium protecting border, miniature LED luminescence chips with Circuit is between protecting border and light guide plate.Protecting border and light guide plate are adhesively fixed with epoxy resin.

It is of the present utility model light emitting directory board used, spot light is become into area source, it is lighter, have colour temperature uniformly, energy-conservation Efficiently, the advantages that long lifespan, various environment be can be widely used in.

Brief description of the drawings

Fig. 1 is the light emitting directory board used schematic perspective view when taking aluminium protecting border state apart of the present utility model.

Embodiment

The embodiment of the utility model energy saving luminous direction board is elaborated below in conjunction with the accompanying drawings.Following examples Son is used to illustrate the utility model, but is not limited to use range of the present utility model.

As Fig. 1 shows the light emitting directory board used schematic perspective view when taking aluminium protecting border state apart of the present utility model, Shown in figure it is described light emitting directory board used, including by light guide plate 1, luminescence chip 2, protecting border 5.The light guide plate 1 is by rectangle Optical grade acryl plates are made, thickness 1.0cm-1.5cm, and luminescence chip 2 is miniature LED white-light emittings chip, protecting border 5 Burnished and fabricated for Aluminum Cutting.Described light emitting directory board used, equidistant brill opens three holes 7, hole in each edge of rectangle light guide plate 1 7 size specification is a little bigger than luminescence chip 2., will be every with electric wire 3 after luminescence chip 2 is installed into the hole 7 of light guide plate 1 respectively Individual luminescence chip 2 connects in parallel, amounts on light guide plate 1 and installs 12 luminescence chips 2.

As Fig. 1 is shown, in the method that the front of the light guide plate 1 uses laser silk-screen, printing destroys the leaded light of light reflection Point forms pictograph 4, lights luminescence chip 2, the light sent is injected inside light guide plate 1 from the side of light guide plate 1, when light arrives The outside of light guide plate 1 is projected after up to the pictograph 4 for not possessing lighting function and forms luminous characters or pattern.

As Fig. 1 is shown, for protect the light guide plate 1 four while and when being embedded in light guide plate 1 on luminescence chip 2, in leaded light Outer on the side of plate 1 four to add the aluminium protecting border 5, luminescence chip 2 and electric wire 3 are between protecting border 5 and light guide plate 1. Protecting border 5 and light guide plate 1 are adhesively fixed with epoxy resin.

As Fig. 1 is shown, the protecting border 5 is formed by four, and there is a string holes 6 wherein one piece of bottom centre, and electric wire 3 is from string holes 6 pass and extraneous connection.

It is of the present utility model light emitting directory board used, it is equal due to having with luminescence chip 2 with parallel way connection and light guide plate 1 Even astigmatism functions, as one of those or several LED luminescence chips are broken, although brightness dies down, normal use is remained to, will not Cause local dimmed.
