[Prior Art] The transmission of light is divided into the advancement of light, the reflection of light, and the refraction of light such as flashlights and front vehicles, which use the light to propagate the light, so that the beam is fired and the single point is increased. Light projection targets can achieve better illumination effects; in addition, such as directional lights, car taillights, etc., the use of these light propagation characteristics, so that the beam dispersion, the illumination area is widely enhanced, so that the rear or side of the person The car can see the hint effect of the lamp. The light-to-polar (led) system--the semiconductor component of 嶋,_ the interaction of the electron holes releases the energy in the form of light, which belongs to the luminescence, has small volume, fast response, long service life and low power consumption. , * face, Nana is like no pollution (four) potential, looking up the society, has become the most popular source of illumination. n ★ (1) LED flashlights sold in the market __ kinds of flashlights with different concentrating effects, to meet the needs of human life in the day; according to the Republic of China invention patent certificate 10 (10) 吁 号 patent "the system is exposed - The LED quick zoom device comprises: a body, the body is internally provided with: a power supply splitting; a (four), the LED is electrically connected to the power supply device, and the fixed end is fixed on the body end-sliding sleeve Slidable setting_body;; convex lens, the convex lens is in front of the It LED, the convex lens can move relative to the convex lens, and the distance between the convex lens and the convex lens is changed by twice the focal length of the convex lens; The sliding sleeve disposed on the body changes. The distance between the LED and the lenticular lens produces different concentrating effects to meet the needs of the user. The above-mentioned quick wipe device 'the fast Wei device of the LED, by sliding the sliding sleeve disposed on the body' to change the distance of the LED from the convex lens, thereby changing the degree of light collection; however, 1378212 in order to change the degree of concentration 'The change of the front and rear position of the Wei slide on the body will cause the length of the LED's speed-changing zoom device to change, resulting in the lack of operation inconvenience; in addition, the (4) fast zoom split is mostly used at night or in the dark. If the person is riding a bicycle at night and use it at the same time. The Xuan LED's speed-focal edge-focusing device performs the lighting function. In order to change the degree of concentrating, the user must slide the sliding sleeve set on the main body, which is inconvenient to use and is prone to traffic accidents. In view of how to operate the fresh-reading Laiware, it is the direction of the development of this solution and the direction of active research and development by people in related fields. SUMMARY OF THE INVENTION The present inventors have intensively studied the improvement and development of rapid change gears in view of the inconvenience of the above-mentioned conventional device during zooming, and finally developed the present invention through continuous county data and efforts. The formula for imaging by a convex lens: l/u+l/v=l/f (u represents the object distance, in the present invention, the distance between the illuminating source and the convex lens, and v represents the image distance. In the present invention, the condensed spot is opposite to the convex lens. The distance 'f represents the focal length of the convex lens), and it is known that the factor of changing the distance of the condensing point from the convex lens is the distance between the illuminating source and the convex lens and the focal length of the lenticular lens. The fast zoom device of the LED described in the prior art is The distance between the illuminating source and the convex lens is changed, so that the distance between the concentrating point and the convex lens is changed, thereby obtaining different concentrating effects, but the lack of operation is lost. Therefore, the object of the present invention is to provide a fast zoom luminaire. Converting the concentrating mirror with the focal length of the wood to achieve the purpose of zooming and causing the degree of concentration to change. The fast zoom lamp of the present invention comprises: a plurality of light sources; • a light film set is fixed at a front end of the plurality of light sources, and the light collecting sheet is provided with a plurality of light holes corresponding to the plurality of light sources; A concentrating mirror disk is rotatably disposed at a front end of the concentrating sheet, and the concentrating mirror disk is provided with a plurality of condensing mirrors corresponding to the light holes and the illuminating source and different focal lengths, and the plurality of condensing mirrors are opposite to the plurality of 13 1378212 The distance of the light source is within twice the focal length of the plurality of concentrating mirrors. Once the concentrating mirror disk is rotated, a plurality of concentrating mirrors on the concentrating mirror disk are also rotated, so as to transmit the light from the plurality of county sources through the plurality of optical apertures through the concentrating mirror. For the purpose of zooming, the poly-precision required for the gamma is generated, and the fast zoom luminaire can be applied to the zoom.
