The utility model comprises a reflection cover for reflecting rays, a light conducting plate body with high light transmittance, at least one light emitting component and a frame covered on the reflection cover, wherein a containing part is arranged on the reflection cover; the light conducting plate body is favorable to the rays to penetrate, and is contained in the containing part of the reflection cover; the light emitting component is contained in the containing part and is positioned between the side edge of the light conducting plate body and the inner edge of the containing part; the light emitting component, the light conducting plate body and the containing part are adjacent.
Description
Technical field
The utility model is about a kind of leaded light module, is meant especially in conjunction with the leaded light module of a kind of reflection subassembly of simplifying step to the light conducting plate body.
Background technology
So-called module backlight, be meant the assembly that a kind of back side of product light source can be provided, be widely used in various information at present, communication, on the consumer products, as LCD (LCD), negative film scanner, lantern slide, products such as projector, wherein being the biggest market as the backlight liquid crystal display member, flourish along with the LCD industry more in recent years, also thereby fast grow up in module backlight market, become one of product that gets most of the attention in the upstream and downstream spare part industry, belong to important spare part, and how to save the raw materials cost of described module backlight, shorten and assemble man-hour, improve make efficiency, and improve all degree and briliancy, be the primary affair in the module industry backlight.
The main spare part of module backlight comprises: light source, light guide plate (Light Guide), reflector plate (Ref1ection Sheet), diffusion sheet (Diffusion Sheet) and prismatic lens (Prism Sheet, or brightening piece Brightness Enhancement Film) etc.Its principle is by a slice light guide plate in simple terms, imports idiopathic light source, as fluorescent tube (CCFL), light emitting diode (LED) etc., to produce bigger, more even and brighter exiting surface; Wherein, after reflector plate provides the light reflection that spontaneous light source is launched, penetrate in the exiting surface of this light guide plate, its advantage is lightweight, high briliancy, good bright dipping visual angle, light utilization ratio height, and simple structureization.Generally in the process of this module backlight of assembling, normally with this spontaneity surface of light source to this light guide plate, except that the exiting surface of this light guide plate, all be covered with reflector plate, this reflector plate provides the high reflection efficiency to visible light, and can be to bottom, the edge cremasteric reflex of this light guide plate, with the luminescence efficiency of the exiting surface of keeping this light guide plate.Wherein, this light source, light guide plate and reflector plate structure group one leaded light module.
See also Fig. 1, known leaded light module shown in Figure 2, comprise light conducting plate body 1a, be arranged at the led lighting module 2a of this light conducting plate body 1a one lateral margin, the cold-cathode tube 4a that is arranged at this led lighting module 2a opposite side and the reflector plate 3a that is covered on this light conducting plate body 1a bottom surface, this reflector plate 3a is by the bottom surface of this light conducting plate body 1a, each place, limit towards this light conducting plate body 1a extends upward and envelopes this light conducting plate body 1a, with the part upper surface of coating to this light conducting plate body 1a.Form known leaded light module thus, further to synthesize module backlight with optical elements sets such as diffusion sheets.Wherein, this led lighting module 2a comprises circuit board 20a, and arrangement is arranged at the most light emitting diode 21a on this circuit board 20a, (its degree of absorption is looked the material of this circuit board 20a itself and the difference of reflectivity thereof for the light of avoiding this light emitting diode 21a is absorbed by circuit board 20a when penetrating, for the light that is sent to this light conducting plate body 1a to a certain degree impairment is arranged promptly), this led lighting module 2a is before being assembled to this light conducting plate body 1a, can be covered with reflector plate 22a prior to this circuit board 20a in the face of this light conducting plate body 1a part in advance, in the hope of reducing the light-absorbing puzzlement of this circuit board 20a.
But the step that pastes this reflector plate 22a is before this led lighting module 2a is assembled to this light conducting plate body 1a, and requires the precision paste; So, discuss design and the sheet number of above-mentioned reflector plate 3a for the present, list is discussed with this reflector plate 3a of single piece type, assemble whole known light conducting plate structure to finishing, at least need to paste for twice the step (being respectively reflector plate 22a and reflector plate 3a) of reflector plate, and above-mentioned two steps are not the action that can finish continuously, the time that more leisure opinion is wasted when the design of this reflector plate 3a or this reflector plate 22a and sheet number trend are complicated, it has lost labor and the anxiety that lowers efficiency in actual assembled and operation.
Moreover, this reflector plate 3a is if desire stably to be coated on this light conducting plate body 1a, it must be in the glutinous agent of appropriate location coating of this reflector plate 3a, and the glutinous agent of coating is except that can causing waste of time, more can cause hindering light, emitted light is influenced around causing exiting surface, also can cause all uneven great disappearances of degree even, and the disappearance that causes briliancy to reduce because of the extinction problem of reflector plate 3a.
The three, this known leaded light module is if desire is formed module backlight, also must be earlier diffusion sheet etc. be placed in the framework (figure does not show), again should known leaded light module place to splice mutually on this framework and form module surely, at last also must be with the whole upset of this quasi-mode group, be placed in again in the metal framework, form known module backlight with structure.Be the program that when assembling, all whole quasi-mode group must be overturn because of it on the practice, and the too disappearance of trouble is arranged.
The inventor promptly thoughts on above-mentioned prior art remain improved, be propose a kind of reasonable in design and effectively get rid of the utility model of its disappearance.
Summary of the invention
The purpose of this utility model is to provide a kind of leaded light module, effectively provides leaded light and reflection function to keep low-cost mode, and can have the effect that processing procedure is simplified and efficient provides concurrently, even also has raising and all spend effect with briliancy.
