The specific embodiment

At first see also Fig. 1, Fig. 1 is a LCD TV indicator lamp schematic diagram of the present utility model.As shown in the figure, the indicator lamp 2 of a strip is arranged at the central authorities belows place of a LCD TV 1, and the user can be by the guiding of this indicator lamp 2, operation with use this LCD TV 1, illuminating module part wherein of the present utility model can be used as the indicator lamp 2 of above-mentioned strip.

Then see also Fig. 2, illuminating module part of the present utility model mainly comprises the light-guiding mechanism 23 of a light emitting diode 21, lens 22 and a hollow; Again, as shown in Figure 3, these lens 22 are a strip structure, are made by the plastic material of a light-permeable, comprise a plane of incidence 221, a display surface 222 and a plurality of screw 223.

In the present embodiment, these lens 22 pass above-mentioned screw 223 by screw (not shown), and lock in admittedly on this light-guiding mechanism 23, and this plane of incidence 221 is positioned at light-guiding mechanism 23 inside of this hollow after assembling.

Again, illuminating module part of the present utility model can send a light by above-mentioned light emitting diode 21, passes said lens 22 and penetrates via this display surface 222; So, by colorful light emitting diode 21 and lens 22, can make this indicator lamp 2 produce the optical signal of tool color, the user can easily discern the signal of this indicator lamp 2 thus.

Then please consult Fig. 4 A and Fig. 4 B simultaneously, this two figure represents the stereogram of above-mentioned light-guiding mechanism 23.Shown in Fig. 4 A, this light-guiding mechanism 23 comprises a depressed part 231, a perforate 232, a screw 234 and a reflecting surface 233; Wherein, this light emitting diode 21 is arranged at this depressed part 231, and its size is rough suitable with this light emitting diode 21, with ccontaining this light emitting diode 21.

Again, above-mentioned reflecting surface 233 is positioned at the inner surface of this light-guiding mechanism 23, but and this reflecting surface 233 be the surface of reflection ray after treatment; So, the light that this light emitting diode 21 sends can enter this lens 22 via this plane of incidence 233 at last by light-guiding mechanism 23 internal reflections of this reflecting surface 233 in hollow.

Shown in Fig. 4 B, these perforate 232 shapes are a strip, and these lens 22 are arranged at above-mentioned perforate 232 places, and wherein these strip lens 22 can insert along an end of above-mentioned perforate 232 and with it in conjunction with (as shown in Figure 2); In addition, above-mentioned light-guiding mechanism 23 also comprises a screw 234, and this light-guiding mechanism passes this screw 234 by screw (not shown) in the present embodiment, thus this light-guiding mechanism 23 is locked in admittedly the inside of this LCD TV 1.

Then see also Fig. 5 again, the figure shows cutaway view by A-A ' cross section among above-mentioned Fig. 2.The direct of travel of the expression light among the figure shown in the arrow, by this diagram as can be seen, 21 emissions of light self-luminous diode can enter this lens 22 by this plane of incidence 221 at last via reflecting surface 233 reflections of above-mentioned light-guiding mechanism 23 inboards; Wherein, because but the utility model is provided with the reflecting surface 233 of reflection ray at the inner surface of the light-guiding mechanism 23 of hollow, so the light that light emitting diode 21 sends can be by these reflecting surface 233 reflections, bootable thus this light is projected to the plane of incidence 221 of these lens 22 equably, and can effectively avoid the loss of light.

In addition, the plane of incidence 221 on these lens 22 also can be earlier via the processing of a cloudy surfaceization, and this plane of incidence 221 can have the function of scattered light thus, and can make that the utility model even brightness effect is more remarkable.

Again, in order to make the above-mentioned feature of the utility model more obvious, see also Fig. 6, Fig. 6 is the side view that is illustrated in B direction visual angle among Fig. 2, wherein the direct of travel of the expression light shown in the arrow.As shown in the figure, but the reflecting surface 233 that has reflection ray by light-guiding mechanism of the present utility model 23 inboards, a plurality of light shafts can enter this lens 22 by this plane of incidence 221 after repeatedly reflecting, and pass these lens 22 and penetrate from display surface 222, this design can become even so that heal at the light of display surface 222.

In addition, the cross section of these lens 22 is one L shaped in the present embodiment as seen from Figure 6, but utilize these light-guiding mechanism 23 inboards to be covered with the reflecting surface 233 of reflection ray, light can after the reflection towards above penetrate, and guide light to pass this display surface 222 thus, so can avoid the scattering and the loss of light, and the brightness that can improve indicator lamp 2.

As mentioned above, be directed to the shortcoming of existing indicator lamp, the utility model is by the light-guiding mechanism 23 of a hollow, but and be provided with the reflecting surface 223 of a reflection ray in these light-guiding mechanism 23 inboards, the utilization reflection way comparable existing more equably with ray cast to the plane of incidence 221 of lens 22, and can improve existing lens because of the distance light source at a distance accept light intensity a little less than, and cause the problem of brightness irregularities easily.

In addition, because all being limited in the inner space of this light-guiding mechanism 23, the utility model light conduct that light emitting diode 21 is sent reflects, so not only can avoid light loss in conduct, can increase substantially the service efficiency of this light emitting diode 21 simultaneously.Compare at illuminating module part with existing, must install the mode of many light-emitting components additional, the effect that the utility model can reach the abundant saving energy really and reduce cost for the strip indicator lamp.
