Description

Composite optical light unit with changing illumination

The present invention relates to a combination luminaire, and more particularly to a combined optical luminaire having a modified illumination light distribution effect.

A known LED optical illuminator currently meets the requirements of different optical shapes through optical lenses and their arrangement. Please refer to a known LED optical luminaire 90 disclosed in FIG. 9 and FIG. 10, which mainly includes a lamp cover 91, a substrate 92, a plurality of LED modules 93, and an optical lens 94. The substrate 91 is disposed inside the lamp cover 91. The substrate 92 is provided with a plurality of LED modules 93. The optical lens 94 is disposed on the substrate 92 and Above the LED module 93.

The optical lens 94 mainly uses the law of refraction in the theory of geometric optics. Two phenomena occur between different media. One phenomenon is that the light is reversed back into the original medium. This phenomenon is called reflection, and another phenomenon Then, the light passes through and enters another medium. Because the medium changes, there is a phenomenon of deflection. This phenomenon is called refraction. When a plurality of LED modules 93 emit light at the same time, the light is incident on the optical lens 94 and is caused by the lens. The proportion adjusted at the time of molding affects the angle of refraction, and part of the light is directly refracted by the optical lens 94 to the illumination direction corresponding to the lamp cover 91, and the other part of the light is refracted by the optical lens 94 for more than one refraction. The grounding is refracted to the illumination direction corresponding to the lamp cover 91.

The LED optical lamp 90 can be generally set up on the road and used as a street lamp. Please refer to the street lamp disclosed in FIG. 11 and FIG. 12 , wherein the lamp cover 91 is horizontally disposed on the first horizontal axis and the second horizontal axis. The plane (ie, the XY plane), the illumination direction is a third axial direction (Z) that is vertically downward, and the illumination effect is achieved by the embodiment; as can be seen from the above, if the illumination light distribution is to be changed, in addition to adjusting the installation height, In addition to the angle, the optical lens 94 and its arrangement still need to be transmitted, but this method requires the use of two or more optical lens combinations, and the optical lens is manufactured to a certain scale to achieve the required light distribution. Therefore, there is a problem that the mold design cost is too high, the proportion of the molding is adjusted, and the development test time is increased.

Therefore, the main object of the present invention is to provide a composite optical lamp set having a modified illumination light distribution, mainly through a luminaire composed of a plurality of light sources, each of which has its corresponding position and each having an adjustable angle. With the light shape, the problem that the design cost of the current technology is too high and the manufacturing process is not easy is solved.

The main technical means adopted for achieving the foregoing purpose is to enable the foregoing composite optical lamp set with changing illumination light distribution, which comprises: a main lamp, wherein the main lamp is internally provided with a main light source, and the illumination direction of the main light source is formed. a main optical axis, the main light source has a fixed horizontal angle and an adjustable elevation angle to change the main optical axis; more than one sub-light, the sub-light is disposed around the main lamp to enhance the main lamp illumination effect, The sub-light is internally provided with a pair of light sources, and the illumination direction of the sub-light source forms a pair of optical axes having an adjustable elevation angle and a horizontal angle to change the sub-optical axis.

In the above lamp, the main light source and the sub-light source each have an illumination light distribution, and when combined with the lamp, the illumination overlap has an effect of enhancing brightness, and the adjustment of the elevation angle and the horizontal angle can form a composite light shape. In turn, the light distribution of the illumination is changed, and the problem that the design cost of the current technology is too high and the manufacturing process is not easy is solved.
