Abstract
The present invention relates to an LED light conductive structure used for a servomotor panel, which utilizes at least one light sensing element to sense whether at least one LED of a casing of the servomotor is lit up. The light sensing element sends a signal to a signal drive circuit in order to light up at least one LED on a panel. By the mode, the disadvantages that the optical attenuation created by using a light conducting system and the panel must be thickened can be eliminated. The present invention further comprises a light conducting post. Utilizing the light conducting post can effectively guide at least one LED light source of the casing of the servomotor to the light sensing element in order to improve the sensing correctness of the light sensing element so as to make a servomotor manager correctly obtain the running conditions of the servomotor.
Description
Technical field
The present invention utilizes at least one leaded light post with the Photosensing Units at least one led light source leaded light to a panel (bezel) on the casing of servomechanism, to drive the LED on this panel relevant for a kind of LED guiding device that is used for the servomechanism panel.
Background technology
Based on security consideration, general server system has a plastic front board (Plastic Bezel) mostly the important device of system is pinned, for example: hard disk, for avoiding unwarranted illegal access, in case the leaking of data.The right ruuning situation that so just can't learn server system, so need LED leaded light post will be positioned at the light source-guide of LED cresset in computer housing the place ahead to plastic front board, to make things convenient for system operator, learn the running status that system is present by the LED cresset on the plastic front board.
See also Fig. 1, it is the servomechanism device synoptic diagram of prior art; As shown in the figure, general servomechanism comprises a casing of servomechanism 10 ' and a panel 20 '; And the place ahead of this casing of servomechanism has a plurality of LED12 ', and panel is provided with a plurality of plastics lamp housings 22 ', but for light source that will these a plurality of LED 12 ' is directed to these a plurality of lamp housings 22 ', must guide light source by a leaded light post 30 ', see also Fig. 2, it is the panel of prior art and the cut-open view of casing of servomechanism; As shown in the figure, because the main purposes of LED leaded light post 30 ' (LED Lens) is to be used to the light signal of the LED 12 ' on this casing of servomechanism is guided on the plastic front board 20 ' by this leaded light post 30 ', make things convenient for the user under the situation of not opening plastic front board 20 ', just can see the signal of LED, learn the state of system.
Existing LED leaded light post is many to be made by the polycarbonate material, utilizes the good speciality of polycarbonate light transmission, and led light source is directed on the plastic front board.But the shortcoming of this kind way is as follows:
(1) distance is longer between LED and the plastics lamp housing, and the decay of light source is more serious, and brightness is difficult to control.
(2) distance is longer between LED and the plastics lamp housing, and its LED leaded light post occupation space is bigger, so the thickness of plastic front board just need thicken, increases the degree of difficulty of design.
(3) based on the physical characteristics of light, the bent angle angle of the LED leaded light post of polycarbonate material can not be too little (can not less than 90 °), not so has the problem of light scattering, so it will increase the degree of difficulty of LED leaded light post wiring.
Because the bent angle of this leaded light post can not be too little, if the vertical range of the plastics lamp housing on the LED position of this casing of servomechanism and the panel is longer, this leaded light post will be very big, cause the thickness increase that must make panel in the design just can cover the volume of this leaded light post, because distance far makes the brightness decay of LED, the thickness of panel is increased and the increase cost.
Summary of the invention
In view of above-mentioned shortcoming of the prior art, the present invention proposes a kind of LED guiding device that is used for the servomechanism panel of novelty.
The LED guiding device that is used for the servomechanism panel of the present invention comprises:
