Description
Technical field
The utility model relates to a kind of many minute surfaces of combined type beam condensing unit, belongs to the luminous lighting apparatus field.
Background technology
Convex lens and concave mirror are optical instruments commonly used in the beam condensing unit, and the transparent mirror body that convex lens are worn into sphere by the two sides is formed, and concave mirror is by simultaneously being concave surface and the opaque mirror body of another side is formed.
Convex lens are to make according to the refraction principle of light.Convex lens are that central authorities are thicker, the lens that the edge is thin.Convex lens are divided into biconvex, plano-convex and concavo-convex forms such as (or positive falcates), and convex lens have converging action so claim collector lens again, effects such as thicker convex lens are then looked in the distance, convergence, and this thickness with lens is relevant.Parallel rays (as sunlight) is parallel to primary optical axis (line of the centre of sphere of two spheres of convex lens is called the primary optical axis of these lens) injects convex lens, light after the two sides of lens is through twice refraction, concentrate on the axle a bit, this point is called the focus of convex lens.Convex lens respectively have a real focus in the both sides of mirror, as when being thin lens, this bifocal to the distance of lens centre about equally.The focal length of convex lens is meant the distance of focus to the lens centre, and the convex lens spherical radius is more little, and focal length is short more.Convex lens can become to stand upside down amplify, etc. big, the real image that dwindles or the virtual image of upright amplification, can converge at focus to directional light, also can become directional light to the light refraction that focus is sent.
The paraboloidal mirror of concave surface, directional light gather on the focus before minute surface by its reflection according to thereon the time, and reflecting surface is a concave surface, focus before mirror, when light source on focus, the light reflection back of being sent forms collimated light beam, also is concave mirror, convergent mirror.Concave mirror not only can make parallel rays converge at focus, and the light that focus is sent is reflected into directional light.
Concave mirror and convex lens imaging contrast:
One, structure difference
1, the convex lens transparent mirror body of wearing into sphere by the two sides is formed,
2, concave mirror is a concave surface and the opaque mirror body of another side is formed by one side.
Two, to the effect difference of light
1, convex lens mainly play the refraction effect to light,
2, concave mirror mainly plays reflex to light.
Existent condenser lens is utilized convex lens and concave mirror mostly, and the light planoconvex lens that light source the sent refraction or the concave mirror reflection back that will be positioned at focus form collimated light beam, to reach the aggtegation of light.But because convex lens only can obtain refraction effect preferably at core, the refraction effect of marginal portion is unsatisfactory; And existing concave mirror is subjected to the restriction of structure itself, the light that light source sent of smaller portions can only be reflected into directional light, and spotlight effect is also undesirable.
In addition, present majority of illumination equipment or adopt single reflector to come optically focused, the utilization rate to light during optically focused is not high, and spotlight effect is relatively poor, can not satisfy the lighting requirement of low-power consumption, high brightness and farther distance.
Summary of the invention
The utility model is at the existing weak point of existent condenser lens, utilize the combination of convex lens and concave mirror, to reach good optically focused effect, the scattered beam that light source can be sent by convex lens refraction and concave mirror reflect to form desirable parallel rays, thereby reach good illuminating effect.Beam condensing unit described in the utility model utilizes the refraction of light and reflection to come optically focused simultaneously, can change more scattered beam into collimated light beam, when improving optically focused greatly to the utilization rate of source light, thereby strengthen the brightness of lighting apparatus.
