CN201289002Y - Reflected refraction type no-glare light source - Google Patents

Abstract

The utility model provides a reflection refraction type no-glaring light source, comprising a refraction body, a metal cup, a metal reflection lamp cage and a LED lamp main body, wherein the light source from the LED lamp main body is reflected by the metal cup along the capwise and the light reenters into the refraction body to be refracted and the inside of the metal reflection lamp cage is an arc surface composed of plane or random scattering surface or square small plane, and the refraction body is set on the focus position of the arc surface of the metal reflection lamp cage, thus the light shape of predicted object is formed according to the design of the arc surface, and the glaring due to high luminance generated by the small area of the LED light source is prevented.

Description

A kind of reflected refraction formula free from glare light source

Technical field

The utility model relates to a kind of light source, relates in particular to a kind of reflected refraction formula free from glare light source.

Background technology

See also shown in Figure 1, existing quartz bulb structure is provided with a light shield 2 in lampshade 1, described light shield 2 has a shielding part 3 with end shield on the light source, only stay light source side light, light is beaten behind described lampshade 1 inner face reflected, make the light source scatter distributions at the lampshade periphery, but the light shield 2 of design not only comparatively bothers in the processing and manufacturing, also, the intensity of light source is weakened with the part light source shielding, unsatisfactory in the use.

In addition, though existing lighting apparatus also has the design of strengthening lateral margin light, as tw Taiwan patent announcement M306299 LED ring shot-light source structure, it mainly is installed with a light-guide device above the metal cup, this light-guide device upper end inner edge has a cambered surface, and be provided with scarf in outside, light-guide device bottom, light emitting diode (LED) scattering that light source produced is provided, refracted ray, can be by the scarf of light-guide device inside and the curvature mirror of cambered surface, cause this light to be formed with the phenomenon of critical angle total reflection, impel this light scattering in the outer periphery of light-guide device, present more light-source brightness to reach LED ring shot-light source structure lateral margin face, but the light scattering also can't provide telecurie irradiation in the outside of light-guide device.

Summary of the invention

Phenomenons such as main purpose of the present utility model is to provide a kind of reflected refraction formula free from glare light source, effectively avoids small size to produce dazzle that high brightness causes, and is dazzling reach efficient concentrated light source in the lampshade periphery.

For reaching aforementioned purpose, the utility model provides a kind of reflected refraction formula free from glare light source, and it comprises:

One LED lamp body is provided with the bottom that screw is locked in the metallic reflection lampshade;

One metal cup, upper limb is extended with a collar flange, and port inwardly forms the conical surface, and the bottom is provided with opening, and described opening is set the protuberance outer rim that is fixedly arranged on described LED lamp body for the metal cup;

One metallic reflection lampshade, inside is provided with cambered surface, and the bottom is a plane, and offers screw, and central authorities are provided with a hole; And

One refractile body, bottom are embedded in the collar flange of described metal cup, and its inside has the circular arc and the conical surface.

Compared with prior art, phenomenon such as the reflected refraction formula free from glare light source that the utility model provides can effectively avoid small size to produce dazzle that high brightness causes, and is dazzling reaches efficient concentrated light source in the lampshade periphery.

The specific embodiment

Below in conjunction with accompanying drawing, be described in more detail with other technical characterictic and advantage the utility model is above-mentioned.

See also Fig. 2, Fig. 3 and shown in Figure 4, the utility model provides a kind of reflected refraction formula free from glare light source, it comprises refractile body 10, metal cup 20, metallic reflection lampshade 30 and LED lamp body 40, on the described LED lamp body 40 screw 410 is set, described LED lamp body 40 can be locked in the bottom of described metal shade 30 by described screw 410; Described metal cup 20 upper limbs are extended with a collar flange 21, and port inwardly forms the conical surface, and the bottom is provided with opening 210, and described opening 210 is set protuberance 42 outer rims that are fixedly arranged on described LED lamp body 40 for described metal cup 20; Described metallic reflection lampshade 30 inside have cambered surface 32, and bottom 31 is a plane, and offer screw 33, and central authorities are provided with a hole 310; Described refractile body 10 bottoms are embedded in the collar flange 21 of described metal cup 20, described refractile body 10 inside have the circular arc 11 and the conical surface 12, the light source that described LED lamp body 40 is sent, earlier via described metal cup 20 reflections, make light be capwise, light enters described refractile body 10 again, make light produce refraction, and described refractile body 10 is arranged at cambered surface 32 focal positions of described metallic reflection lampshade 30, cause the design of light according to described cambered surface 32, form the light shape of scheduled target, reach and eliminate led light source because of small size generation dazzle that high brightness causes, phenomenon such as dazzling.

More than explanation is just illustrative for the utility model; and it is nonrestrictive; those of ordinary skills understand; under the situation of the spirit and scope that do not break away from following claims and limited; can make many modifications; change, or equivalence, but all will fall in the protection domain of the present utility model.
