The refraction is divided into a low light amount region and a high light amount region 7 as long as the second light_total light amount is in the area of the towel, and the second light_light amount is not wasted as much as possible.疋f [_] The light that strikes the amount of light can be set along the main optical axis. _ Several of these anti-combination counters are used to set the light source of the difficult (4) level. a high-light-amount region is formed in the peripheral portion, and a low-light-quantity region=^bepass-through hole is formed, and the south-light-amount region is incident on the reflective surface, and the light/optical axis reflected by the reflective surface overlaps with the main optical axis to be adjacent to the second light. , [0020] No.! The second light-emitting element may be, for example, an LED, as a specific embodiment of the light source and the second light source. [0021] i The light accumulating device is regarded as a unit, and in the same way, the lighting device is configured to be more precise than the light of the structure r "I" based on the main optical axis of the i cells. 】 The hair extension device can be used for the headlights to obtain high light amount and can be prevented from being used as the base; the light accumulating device of the present invention uses the main optical axis to the limited headlights. Space is subject to [compared with the prior art] [0023] 201000822 According to the light accumulating device of the J structure, the light is advanced by the way of light tilting, so that the high-light-amount region emitted by m can be made to be incident on the reflecting surface. , = shoots the through hole in the field, and illuminates the light in the middle. Furthermore, the i hi ^ rule is reflected. Therefore, it can be separated from the second light source by the high efficiency source, so it can prevent the problem. In addition, since it is not necessary The plurality of light sources are arranged side by side in the same plane as the alignment light emission ==, so that the main optical axis can be simplified. [Embodiment] Hereinafter, the present invention will be described with reference to the drawings. [0027] ~ [οοίΓ _ light accumulation device _, can be used as # light source for car headlights. Specifically, in the light accumulating device of the present embodiment, as shown in the figure, the reflecting surface Μ12 of the first reflecting mirror is disposed in a state relative to the main optical axis L, and is provided with a central axis and a main optical axis L. The overlapping through holes Mh; and the passage 1' emit a first light that overlaps the optical axis u from the back side of the first mirror M1 toward the front side; and the second light source 2 is disposed offset from the main optical axis The flute can emit a second ray of the vertical main optical axis toward the reflecting surface M12 of the mirror M1. The second ray reflected by the reflecting surface M12 of the wire is overlapped with the main optical axis L· and the first ray亢 前进 。 , , 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该[0030] The first light source 1 includes a first LED 11 that is an ith illuminating element, and an optical element 12 that focuses the beam of the first 射 that is emitted by the first Π 20 201000822 into the through hole Μ [0031] The first optical element 12 includes a first LED lens 121 that concentrates the first LED 11 and emits a line 'to reduce the size of the beam; and a first plano-convex lens 122 disposed at a distance from the light exit end of the LED 1 lens 121, as shown in FIG. 2, the first LED lens 121 is concentrated (1) The second light source 2 includes a second LED 21' as a second light-emitting element, and a second optical element 22, the second light emitted from the second LED 21 The center portion is formed with the low light amount region Lo, and the high light amount region ff1 is formed in the peripheral portion. Further, the second LED 21 and the first LED 11 are the same type of LED, and the same wavelength can be emitted. [0033] The second optical element 22 includes: The 2LED lens 221 converts the second light emitted by the second LED 21 into parallel light, and the second lenticular lens 222 is disposed at a position spaced apart from the light emitting end of the second LED lens 221.

Further, since the first optical element 12 reduces the beam size of the light beam by 201000822 to the size of the through hole Mj1 so as to pass through the through hole Mn, approximately all of the light can pass. The light of the high-light-quantity area ffi is reflected by the reflection surface, so that only a very small portion of the light contained in the low-range H-domain Lo is lost, and it is merged with the second-order light. Therefore, the first LED 11 and the second LEm can be collectively set. The towel's light with high efficiency.

Further, since the light source is added along the main optical axis L, it is possible to produce light of a higher amount of light when the radial structure based on the main optical axis 1 is kept compact. Further, the present invention is not limited to the above embodiment. [0048] For example, the light accumulating device can be regarded as a unit, and then a plurality of cells are combined on the same plane to make a huge light source that can emit high-intensity light. Since the radial structure with reference to the main optical axis L of j in every j single 很 is very compact, even if a high-light ray is produced side by side in this way, it is possible to streamline the radial structure based on the squad. Further, as shown in FIG. 4, in the second optical element 22, a lenticular lens 222 of the center portion 221 2221 may be used. With these members, the light incident on the center of the lenticular lens 2 is refracted toward the portion, and a low light amount region can be formed at the center portion to form the surface light amount region Hi on the peripheral portion. In addition, the LED that emits light can be a surface light source or a point light source. [0050] The measurement area is in the low light amount 11 field 'high light amount is formed in the peripheral portion, and the light distribution characteristic of =1 is low light is formed in the central portion. [0051] ^The first light and the second light are concentrated. The light quantity is set; the output quantity 1 is further superimposed on the main optical axis in the same manner as the third light source - the light emitted from the front ^ is the second light source or the third light source can also be used in the light (four) light energy to the main light Axis 12 201000822 ^ Tilt mode setting. In this case, the configuration of the optical accumulating device can be further simplified in the radial direction based on the main optical axis. [0054] The mirror is limited to circular weaving, and it is necessary to have a reflecting surface and a through hole. For example, the mirror may have a shape in which the side surface is cut obliquely, and the cross section has a reflecting surface, and has a beacon hole penetrating from the center of the bottom surface toward the center of the butterfly. ^ The shape of the through hole of the mirror is not limited to various shapes such as a rectangular shape. Also, J rnn <d [0055] For example, a diffraction grating may be used to refract the first light and refract the second light into a low light amount region, and the optical element is not limited to the lens light beam to form the through hole size and the high light amount region. [0056] The cathode member is not limited to the LED, and may be an organic EL, a xenon lamp, a xenon lamp, or a cold. [0057] The accumulating device may be used as a light source for a projector or the like in addition to the headlight.
