Abstract
The invention discloses a kind of lens treatment process for zooming LED lamp, frosted process is carried out to the single curved surface of lens or plane, makes the surfaceness of described single curved surface or plane be 25.4 ~ 63.5 microns.The invention has the advantages that after frosted process is carried out to the single curved surface of described lens or plane, the hot spot for irradiating out after zooming LED lamp is made evenly not have obvious border, floodlighting and spotlighting is realized from interior in short varifocal, avoid obvious border and the imaging problem of hot spot, for Cultural relics in museum illumination provides good illuminating effect.
Description
Technical field
The present invention relates to optical lens treatment process, especially relate to the lens treatment process for zooming LED lamp.
Background technology
Museum is one and requires very strong place to illumination artistry, but due to the restriction of technical conditions, is up to the present also really applicable to the light fixture of the illumination such as museum and art exhibition.The existing zoom lighting for museum's art exhibition cabinet, although can change by focusing the size being radiated at hot spot on object, but the border of hot spot clearly, as shown in Figure 1, particularly get to after on calligraphy and painting, the sharp trace of hot spot will affect appreciation effect, and the artistic effect of historical relic can not be embodied well, reduces the culture and arts sense of historical relic.
Summary of the invention
The object of the invention is to provide a kind of lens treatment process for zooming LED lamp.
For achieving the above object, the present invention takes following technical proposals:
Lens treatment process for zooming LED lamp of the present invention, carries out frosted process to the single curved surface of lens or plane, makes the surfaceness of described single curved surface or plane be 25.4 ~ 63.5 microns.
Described frosted process adopts emery, silica sand, pomegranate powder abrasive material to carry out mechanical lapping or hand-ground to the single curved surface of lens or plane, or adopts hydrofluoric acid solution to carry out roughness processing to the curved surface of lens.
Described lens are plano-convex lens, biconvex lens or concave-convex lens.
The invention has the advantages that after frosted process is carried out to the single curved surface of described lens or plane, the hot spot for irradiating out after zooming LED lamp is made evenly not have obvious border, as shown in Figure 2, floodlighting and spotlighting is realized from interior in short varifocal, avoid obvious border and the imaging problem of hot spot, for Cultural relics in museum illumination provides good illuminating effect.
Accompanying drawing explanation
Fig. 1 is the existing hot spot design sketch for zooming LED lamp lens.
Fig. 2 be according to present invention process process after lens for the hot spot design sketch of zooming LED lamp.
Fig. 3 is the structural representation of plano-convex lens of the present invention.
Fig. 4 is the structural representation of biconvex lens of the present invention.
Fig. 5 is the structural representation of concave-convex lens of the present invention.
Embodiment
Lens treatment process for zooming LED lamp of the present invention, carries out frosted process to the single curved surface of lens or plane, makes the single curved surface of described lens or the surfaceness of plane be 25.4 ~ 63.5 microns; Described lens are for plano-convex lens 1 as shown in Figure 3 or for the biconvex lens 2 shown in Fig. 4 or be the concave-convex lens 3 shown in Fig. 5.Described frosted process adopts emery, silica sand, pomegranate powder abrasive material to carry out mechanical lapping or hand-ground to the curved surface of said lens, or adopt hydrofluoric acid solution to carry out roughness processing to the curved surface of lens.
Claims (2)
1. for a lens treatment process for zooming LED lamp, it is characterized in that: frosted process is carried out to the single curved surface of lens or plane, makes the surfaceness of described single curved surface or plane be 25.4 ~ 63.5 microns; Described frosted process adopts emery, silica sand, pomegranate powder abrasive material to carry out mechanical lapping or hand-ground to the single curved surface of lens or plane, or adopts hydrofluoric acid solution to carry out roughness processing to the curved surface of lens.
