New description: [New technical field] The creation is _-Juguang II _ luminaire, and the system is related to a light-emitting diode lamp with a light guiding element. [Prior Art] A light-emitting diode (LED) is a new generation of lighting elements, which has the advantages of power saving and long service life, and has been widely used in various types (4)/lamps. For example, the illuminator can be a f-light source of a display, a lighting fixture of a house, or a special lighting fixture of a traffic ray. _, in order to carry out the e-circumference of the brightness and chroma of the light source, it is necessary to further set the light sensing component in the lighting fixture for feedback control. However, the general light sensing element is directly disposed on the light exiting path of the light source for sensing operation, which will seriously affect the luminous efficiency of the overall light source. For example, a light-emitting two-domain flat display (such as a liquid crystal display) for riding a yang "when the panel size is increased", the number of light-emitting diodes disposed at the f-light source and the light-sensing element must be increased. However, more light sensing components will block the $ silk leakage material, which will result in an increase in the cost of production due to the illuminating effect of the overall light source.

The above and other objects, features and advantages of the present invention will become more apparent. The following description of the preferred embodiments will be described in detail with reference to the accompanying drawings. FIG. 1 is a structural diagram of a light-emitting diode lamp according to an embodiment of the present invention. Referring to FIG. 1 , the light-emitting diode lamp 100 includes a light-emitting diode light source 10, a light guiding element 11, and a light sense. The light-emitting diode light source 10 has an LED light-emitting surface 27, and the light-emitting diode emits light through the LED light-emitting surface 27, and the light 201 shown in the figure is merely an example. The light-emitting diode light source 10 includes one or more wavelength light-emitting diode elements, and different types of light-emitting diode elements emit different wavelengths depending on the grain material or the phosphor powder composition. The light of the visible light of the human eye ranges from 400 nm to 700 nm, and can produce light of different colors, such as blue light, green light, yellow light, orange light or red light, according to the light Composition of different light-emitting diodes The body element is as shown in Fig. 2, but the creation M405541 does not limit the structure of the figure. Referring back to Fig. 1 in May, the above-mentioned light guiding element 11 is disposed in the light emitting diode lamp 100, and is disposed in the first pole of the light emitting diode. Above the body light source ίο, the light guiding element Π has a light incident surface 20 for collecting light, and a light emitting surface 21 for emitting light. The following is explained by the light 201 emitted by the LED light emitting surface 27. The light emitted by the LED light-emitting surface 27 is very similar to the light-emitting surface 27 of the LED, which is similar to the light 201 emitted by one side. In order to simplify the space, the following will not specifically describe the light, wherein the light-emitting diode light source 10 emits the above-mentioned light 201. It is introduced into the light guiding element 11 through the light incident surface 20, and then the light ray 2 is totally reflected in the light guiding element and transmitted through the light emitting surface 21. In this example, the light guiding element 11 can be light-transmitted. The housing is, for example, one of a bulb housing, a lamp covering or a light guide plate. As described above, the photo sensor 12 is also disposed in the LED illuminator 100, and the photo sensor can be set. Attached to the light-emitting surface 21 of the light guiding element u Between the light-incident surface 20 and the light-emitting surface 21, as long as it is not in the light-emitting path of the light-emitting diode light source 10, the light-emitting efficiency can be effectively maintained. Therefore, the light sensor 12 is preferably disposed on the path of the light-emitting surface 21 The light ray 201 is led to the light sensor 21 through the light emitting surface 21 of the light guiding element to generate a sensing result. The sensing result is defined as the light sensing signal LS. As for the controller 13 described above, it is also configured to emit light. In the diode lamp 1 (8), the controller I is electrically connected between the light emitting diode light source 10 and the light sensor 12, wherein the controller can preset a predetermined light data 'where the preset light data is preset The color temperature data, the color data, the illuminance data, the light intensity data or the luminance data may be included, and the light compensation of the light emitting diode light source 10 according to the preset light data is determined according to the sensing result generated by the light sensor 12 . For example, when the light intensity emitted by the light-emitting diode light source 1〇7 M405541 of the light-emitting diode lamp 100 is less than the preset light data, the controller 13 senses the light generated by the light sensor 12. As a result (that is, the above-described light sensing signal ls), it is determined that the difference between the light sensing signal LS and the preset light data is compensated, thereby increasing the light intensity of the light-emitting diode light source 10. On the other hand, when the light intensity emitted by the light-emitting diode light source 10 of the light-emitting diode lamp 100 is greater than the preset light intensity data, the controller 13 generates a light sensing result according to the light sensor 12 (light perception). The measurement signal LS) is determined to compensate according to the difference between the light sensing signal LS and the preset light intensity data, thereby reducing the light intensity of the light emitting diode light source. However, in the above-described flat panel display using the light-emitting diode as a backlight, the heat generated by long-term use tends to cause the light-emitting color of the light-emitting diode to shift. Under the standard of high color quality of the display, when the color of the light emitted by the light-emitting diode source 10 is offset by the preset light color data, then the control of the crying 13 will be based on the light sensing signal LS and the pre-measurement. The difference value between the light color data is set to further adjust the color balance of the light-emitting diode light source 10. 8. It should be additionally explained that 'the light sensing signal LS generated by the photo sensor 12 may include one of color temperature data, color data, illuminance data, and light intensity data disk luminance data transmitted to the controller 13 to perform correspondence. The operation, and the related operations are quite similar to those shown in the above embodiments, and will not be described here. According to the above description, the light-emitting diode lamp of the present invention can not only be used as a light source for the light guiding element, but also can be used as a light source without causing inferior light output efficiency. Stable feedback system. Second Embodiment: Fig. 3 is a perspective view of a light-emitting diode lamp according to another embodiment of the present invention. Referring to FIG. 3 and FIG. 3 together, the LED lamp of the present invention is different from the LED lamp 100 shown in FIG. 1 in the photosensor 12 in the LED lamp 300. It is implemented by including temperature sensing element 14. In this example, the temperature sensing element 14 is integrated into the package of the photo sensor π, so the photo sensor 12 needs to have a temperature detecting area for the temperature sensing element 14 to sense the temperature. In this embodiment, the ambient temperature of the light-emitting diode lamp 300 is the light-emitting power (i.e., the generated heat energy) consumed by the light-emitting diode light source. The temperature detecting area 51 of the photo sensor 12 senses the temperature change of the light emitting diode light source, thereby generating the temperature sensing signal TS, and transmits the temperature sensing signal TS to the controller 13 through the wire. The controller 13 presets a preset temperature value, and determines, according to the sensing result generated by the temperature sensing component 14 (ie, the temperature sensing signal TS described above), the LED light source 1 is performed according to the preset temperature value. The temperature of the crucible is rounded up. Therefore, the controller determines whether the ambient temperature of the LED device 3 咼 is at a preset temperature value by the temperature f sensing signal TS ′ generated by the temperature sensing element 14 . For example, when the temperature sensing element ts generated by the temperature sensing component 14 is higher than the preset temperature value, then the controller 13 generates a sensing result (temperature sensing signal) generated by the temperature sensing component 14. And it is necessary to compensate according to the difference between the 'TS sense ## TS and the preset temperature value, and to lower the luminous power of the light-emitting diode light source 10. Thus, when the ambient temperature of the light-emitting diode lamp 300 is higher than the preset temperature value, the controller 13 can determine to lower the light-emitting power according to the temperature f-measurement signal generated by the temperature sensing element 14. Therefore, the light-emitting diode and the "3" city temperature are within the preset temperature range, thereby prolonging the service life of the above-mentioned light-emitting diode element. The light-emitting diode lamp/, the W component is divided into the wire and the wire, and the light is emitted on the light guide M405541, or (4) the field is measured to make the physical quantity on the light path (the light is Whether the offset is offset from the preset value to generate the sensing result, and the controller in the above-mentioned light-emitting diode lamp determines whether the height is lower/lower than the preset according to the sensing result (light sensing signal) a value (preset optical data) to adjust the illumination behavior of the light-emitting diode source; however, the temperature sensing element integrated in the photo sensor is offset from the preset value according to another physical quantity (which is a temperature change). To generate another sensing result, the controller determines, according to another sensing result (temperature sensing signal), whether it is higher than a preset value (preset temperature value) to adjust the lighting power of the light emitting diode light source. The luminous LED lamp of this creation can not only be used The light guiding of the light-emitting diode light source can also be used as a compensation for the change of the light-emitting diode light source and the change of the ambient temperature without affecting the light-emitting efficiency. Although the present invention has been disclosed above in the preferred embodiment, It is not intended to limit the creation of this work. Anyone who is familiar with this skill can make some changes and refinements without departing from the spirit of this creation. Therefore, the protection scope of this creation is subject to the definition of the patent scope.
