[Prior Art] In the field of camera use, when Eclipse is known, 夕忠,®-Friends also use Xenon as the source of the flash, and the xenon lamp uses the flash between the electrodes. Xenon lamp main H... machine (4) seat "Spectrum is very flat and produced 胄", spectral in visible light (four), and other advantages are perfect and in line with human vision, especially due to the filling of gas helium A. Time (Warm_uPtime) is very short and dangerous; but its main disadvantage is that it emits: inert gas' so there is no danger of explosion, and it will produce too much efficiency when used, and the lamp life is short. Quite power consumption, so that the heat flow ° when the xenon lamp is used in the camera's camera image sensor must be used, the flash can not be used frequently, this shape adjustment to avoid too bright or too dark. Miscellaneous control or software for sensitivity The light-emitting diode (LED) is directly converted into light energy by using the positive and negative electrodes of the semiconductor. The light is added to the light in the factory, and the energy is released by combining the holes, and the electrons are Electric body The principle of light. The form of the light-emitting diode is released. This is the difference between the light-emitting diodes and the photon energy, which makes the photon energy production different, and the energy of the material is long. The light-emitting diode has a volume of 3 M348967. The advantages of light weight, fast response and no pollution, these advantages make the application field of light-emitting diodes gradually reach various industries, and the high-power light-emitting diodes have been gradually developed due to scientific and technological progress to solve the problem of insufficient brightness. The light-emitting diode can also be applied to the field of illumination light sources. In recent years, the development of high-performance LEDs, which have higher brightness than the previous LEDs, can be applied to lighting and cameras; Continuous use for a short period of time, enough to allow the camera image sensing device to adjust the brightness; LED has been gradually developed for use in cameras or cell phone cameras to replace traditional xenon lamps, such as US Patent US2007/195176, US2003/216151, Japanese Patent JP10-039795 Etc. However, the brightness of the LED single is still insufficient, and it is often necessary to use multiple LEDs to form an LED array (LED Array).

Patent US 7,136,672, US 2003/218689, US 7,236,697, Japanese Patent JP2006-173622, etc. Since the brightness of LED is much lower than the brightness of conventional xenon lamps, it is far less than the brightness of conventional gas lamps, and only for LED arrays required for photography. The composition of several LEDs, if not properly arranged, the light is at the target, the brightness can not be uniform, $ is suitable for camera shooting, such as shooting portraits will produce different brightness; Furthermore, the use of pulse technology ( Pulse) or time control may cause unevenness in each LED. In addition to power consumption, the light type of the reservation cannot be achieved. The conventional LED flash lamp can be composed of the LED light source 23 as shown in FIG. 1. After the LED chip 233 on the LED substrate 24 emits light, it is reflected and concentrated via a parabolic reflector 28, and is irradiated onto the target.
