Abstract

Provided is an anti-dazzle LED (light-emitting diode) lamp reflecting bowl and a lamp. The internal face of the reflecting bowl is composed of or provided with a plurality of reflecting scales. A support just below the reflecting bowl is provided with a LED light source; the top of the reflecting bowl is provided with a lamp radiator and a drive circuit of the LED light source. Each reflecting scale mixes and superposes rays of light emitted by the LED light source to surfaces needing lighting and to form uniform transition lighting effects, which can meanwhile reduce an emitting face height of the lamp and solves the dazzle problem of the lamp.

Description

LED light fixture reflector and light fixture thereof that anti-glare is dazzling

Technical field

The utility model relates to the LED field of lamp illumination, particularly relates to dazzling LED light fixture reflector of a kind of anti-glare and LED light fixture.

Background technology

LED has been widely used in various lightings as the novel energy-conserving light source, as the PAR lamp of indoor use, the street lamp of outdoor application, Tunnel Lamp, advertising lamp etc.Because of a large amount of uses of indoor LED light fixture, the LED light fixture of present indoor use has been proposed the abblendbar requirements at the higher level, light fixture can't be realized these requirements usually now.

With reference to Fig. 1 and Fig. 2, be the used light fixture of room lighting of the prior art, described LED lamp be with many independently LED pipe 210 be arranged in the PCB(wiring board uniformly) on 220, quantity and all corresponding with it lens 110 in position are installed below every LEDs pipe 210, every lens are controlled corresponding LED pipe 210 light that send, can finish the luminous intensity distribution of various angles, the bore of single light-distribution lens making is generally less relatively, be generally less than 20mm, beam projecting face light energy is comparatively concentrated.The LED light fixture of this kind form can solve the luminous energy distribution problem of irradiation area preferably, but do not solve the optics outgoing brightness problem of light fixture, when therefore the people looks at this type of light fixture of lighting straight, because the optical brightness value height of its exiting surface will produce dazzling and dazzling sensation.

The utility model content

The purpose of this utility model provides the dazzling LED light fixture reflector of a kind of anti-glare.

This novel purpose is achieved in that the LED light fixture reflector that a kind of anti-glare is dazzling, the reflector internal face form by a plurality of reflective scales or the reflector internal face on a plurality of reflective scales are arranged.

Above-mentioned reflective scale is plane or curve form.

Above-mentioned reflective scale is distributed on a plurality of endless belt.

Above-mentioned reflective scale is the organic plates that the surface is coated with reflective membrane, and perhaps, reflective scale is the metallic plate that the surface is coated with reflective membrane, and perhaps, reflective scale is the glass plate that the surface is coated with reflective membrane.

Another purpose of the present utility model provides a kind of LED light fixture that adopts above-mentioned reflector.

This another novel purpose is achieved in that a kind of LED lighting with reflector, is provided with led light source above the support under the reflector, and the reflector top is provided with the drive circuit of lamp radiator and led light source.

This New LED reflector, its reflective surface is made up of a plurality of scales that clocklike, have a reflective characteristic.Place led light source on the other side in reflector or under outer, each reflective scale carries out shaping on demand to the received light that is sent by LED and distributes, being added to then needs the zone of illumination, adopt the LED light fixture of this reflector structure, can be separated into a plurality of led light source pictures to led light source, guarantee to reduce the outgoing brightness of light fixture under the prerequisite that the required luminous energy in field of illumination distributes like this, so when human eye direct-view light fixture, and do not think dazzling dazzling.By changing face shape, quantity, spatial attitude and the arrangement mode etc. of reflective scale, can realize that the various smooth shape that the LED indoor illumination light fitting needs distributes, as required usually 15 °, 20 °, 24 °, 30 °, 45 ° (light beam shooting angles) etc.

Place led light source on the other side under reflector, the light that led light source sends reflects by scale, and stack shines the zone that needs illumination.Reflector with this feature can be separated into a plurality of pictures to led light source, thereby has solved the problem that common LED light fixture is dazzling and dazzle the eyes.

Description of drawings

Fig. 1 is the vertical view of a kind of LED light fixture of prior art.

Fig. 2 is the front view (broken section) of light fixture shown in Figure 1.

Fig. 3 is the stereogram of this novel embodiment.

Fig. 4 is the stereogram of the LED light fixture of the described reflector formation of this novel employing.

The specific embodiment

Below in conjunction with drawings and Examples, further describe in detail originally novel.

Referring to Fig. 3, the LED light fixture reflector that a kind of anti-glare is dazzling, reflector internal face form by a plurality of reflective scales or the reflector internal face on a plurality of reflective scales are arranged.Reflective scale 311 is plane or curve form.Reflective scale 311 is distributed on a plurality of endless belt 310.Reflective scale is the organic plates that the surface is coated with reflective membrane, and perhaps, reflective scale is the metallic plate that the surface is coated with reflective membrane, and perhaps, reflective scale is the glass plate that the surface is coated with reflective membrane.

Reflector is to form at inwall plating reflective membrane after adopting the organic material injection moulding; Reflector also can adopt the metal material with reflective characteristic to be stamped to form; Reflector forms at inwall plating reflective membrane after also can adopting the metal material punching press; Reflector can also adopt glass heat molded, at inwall plating reflective membrane.

Referring to Fig. 4, a kind of LED lighting with reflector is provided with led light source 420 above the support under the reflector, and the reflector top is provided with the drive circuit of lamp radiator 430 and led light source.

Fig. 3 is this first novel embodiment.The inwall of this reflector divides for a plurality of endless belt 310 along the circumferencial direction of reflector, and each endless belt 310 is made up of a plurality of reflective scales 311, and the scale face shape unanimity of same endless belt can be that the plane also can be a curved surface, only is that the position in space is inconsistent.

The endless belt number of reflector inwall and the scale quantity of each ring mainly are to be optimized design according to the uniformity of the light energy distribution on the illuminated area and the outgoing brightness of the exiting surface of light fixture own; The reflective scale face shape of each endless belt is optimized design according to condition of incidence and the luminous energy distribution of needs illuminated area and the shooting angle of light fixture etc. of led light source.

Like this, the light that each reflective scale 311 sends led light source, mixing is added to needs will form the illuminating effect of even transition on the face of illumination.

For better this novel described reflector of explanation and the application in the LED light fixture, Fig. 4 has provided a kind of Novel LED lamp schematic perspective view that this novel described reflector constitutes of using, led light source 420 be placed on reflector 410 under, the light that led light source 420 sends is distributed to the field of illumination through the reflection of reflector 410 inwall ramentums, and the heat that led light source sends is transmitted on the lamp radiator 430 through heat conducting elements such as metal or pottery 440.

The above only is this novel preferred embodiment, and this is not novel in order to restriction, every any modification of being done within this novel design philosophy and principle, is equal to and replaces and improvement etc., all should be included within this novel protected scope.
