CN2334999Y - Glare-resistant board with reflection/refraction function for illumination appliance - Google Patents

Abstract

The utility model relates to an indoor lamp, which solves the antiglare problem, an illuminating appliance is provided with an antiglare plate having the reflecting and the refraction functions, and the antiglare plate comprises arc-shaped spherical lens units. The utility model is characterized in that the arc-shaped spherical lens unites form an array, each arc-shaped spherical lens unit comprises an upward concave surface and a downward convex surface, and the top edges of the arc-shaped spherical lens units are in the adjacency. The light rays of the light source can be reflected back through the arc-shaped spherical surfaces in the glare zone, and are sent out; the light rays in the non glare zone can transmit each arc-shaped spherical lens unit, and the brightness and the glare preventing effects can be achieved. The utility model is used for the illumination.

Description

Ligthing paraphernalia has the antiglare shield of catadioptric effect

The utility model relates to indoor illumination light fitting, refers in particular to a kind of antiglare shield of light fixture.

Existing indoor lamp, especially lamp affixed to the ceiling when preventing that dazzle is dazzling, often hide with white baffle plate, but stopping that dazzle simultaneously, has also stopped brightness, therefore in order to stop dazzle, enough brightness are arranged again, often increase luminosity; Another kind as shown in Figure 1, the installing screen is stopping dazzle, but effect is relatively poor, and still very easily directly is shining into from the oblique screen space that sees through, and people are felt very ill.

The purpose of this utility model is to provide a kind of brightness and antiglare shield with catadioptric effect that prevents dazzle taken into account.

The purpose of this utility model is achieved in that ligthing paraphernalia has the antiglare shield of catadioptric effect, and it comprises the arc spherical lens elements, it is characterized in that; Consist of the array lamellar body by each arc spherical lens elements, each arc spherical lens elements contains a concave surface that makes progress and a downward convex surface, and the apical margin of each arc spherical lens elements is adjacent to each other.

Above-mentioned design, the light that light source produces can see through in glare area sends after the arc sphere reflects back again; And only allow the light penetration of non-glare area cross each arc spherical lens elements, reach the effect of taking into account brightness and preventing dazzle.

The utility model is remake further bright below by drawings and Examples:

Fig. 1 has anti-dazzle screen organigram now;

Fig. 2 the utility model constructing stereo schematic diagram;

Fig. 3 the utility model light passes schematic diagram;

Fig. 4 the utility model light refraction schematic diagram;

Another embodiment cutaway view of Fig. 5 the utility model;

Shown in Fig. 2,3, the utility model comprises arc spherical lens elements 1, it is characterized in that: consist of the array lamellar body by each arc spherical lens elements 1, each arc spherical lens elements 1 contains a concave surface that makes progress 11 and a downward convex surface 12, and the apical margin of each arc spherical lens elements 1 is adjacent to each other.Useful light 3 is only through the arc spherical lens elements and without glare area 4.

As shown in Figure 4: dazzle light 5 is reflected by arc spherical lens elements 1 of the present utility model.

As shown in Figure 5: the concave surface 11 in each arc spherical lens elements 1 is provided with light diffusion dull and stereotyped 6.Each arc spherical lens elements 1 is made for the transparent fat material of moulding.
