Problems solved by technology

The scale-type reflective cup formed by one-time demoulding can be adjusted during the model design, so its optical accuracy is high, but it needs to open a mold, the cost is high, and once the damage occurs, the entire scale-type reflective cup needs to be replaced; the other The multi-scale reflective cup is a "combination" of the same lens.

Example Embodiment

[0068] The present invention will be described in detail below with reference to the drawings and specific embodiments.

[0069] Such as figure 1 with figure 2 Shown is the structure diagram of the scale reflector cup of the first embodiment of the scale reflector lamp of the present invention, wherein figure 1 Is a perspective view of the scale-type reflector cup of the first embodiment, figure 2 It is a front view of the flaky reflector cup of the first embodiment.

[0070] In the first embodiment of the scaly reflector lamp of the present invention, the scaly reflector cup 2 is a rectangular parallelepiped material and formed by etching, and the etched surface of the scaly reflector cup 2 is a free-form curved surface composed of triangular mirror units 22. The specific shape of the etched surface is determined by the following initial conditions:

[0071] In this embodiment, the light source is selected as a 2.2mm×2.2mm Lambertian surface light source, which is illuminated at a...

Abstract

The invention relates to a squama-type reflection lamp and a design method thereof. The lamp comprises a light source and a squama-type reflection cup, the light source is arranged on the right front position of an optic midpoint of the squama-type reflection cup, the squama-type reflection cup comprises a plurality of mirror surface units which are jointed through the following method: enabling the light source position, the optic midpoint of the squama-type reflection cup, a shape and the position of anticipated facula to be served as initial conditions, determining positions of mirror surface unit nodes passing through a meridian line according to the geometrical optic image-forming principle; iterating the positions of mirror surface unit nodes of other positions on the squama-type reflection cup by using the geometrical optic iteration principle according to the position of the mirror surface unit nodes on the meridian line, and determining positions of the mirror surface units. The lamp is good in lighting uniformity, can obtain sharp edges, and can conduct shape cutting according to requirements.

Description

technical field [0001] The invention relates to the field of lighting, and more specifically, to a scale reflective lamp and a design method thereof. Background technique [0002] In the lighting of lamps, there are often specific requirements for the light spot. For example, in the dental light, the dental light needs to be able to produce a rectangular light spot, so as to provide sufficient brightness of illumination without causing dazzling discomfort to the patient. Usually, the way to control the spot is to formulate a special scale-type reflective cup, so that the light source will produce the expected spot after being reflected by the scale-type reflective cup. [0003] The common scale reflective cups can be divided into two types: one is the scale reflective cup that is directly molded at one time according to the light distribution requirements, and the other is the scale reflective cup that is "combined" with the same lens. The scale-type reflective cup formed b...
