Description
Technical field
The utility model relates to a kind of reflex reflector that is used for Down lamp.
Background technology
Down lamp is a kind of lighting that is embedded into light down-ejection type in the ceiling, and Down lamp generally comprises a screw socket, can directly load onto the light fixture of incandescent lamp or electricity-saving lamp, is used for market, hotel, family or coffee shop more.Can adopt different reflectors, eyeglass, shutter, bulb, obtain different light effects.
The fitting structure of current Down lamp is fairly simple, it is cylindric that the shape of its internal reflection plate also mostly is, the light that such fitting structure can not send fluorescent tube is reflection fully downwards, reduced the problem of the service efficiency of light, and Down lamp also can in use produce dazzle.
Therefore the structure of a kind of reflex reflector that is used for Down lamp newly of current needs solves the problems referred to above.
The utility model content
Technical problem to be solved in the utility model provides a kind of reflex reflector that is used for Down lamp, has solved the relatively simple for structure of current Down lamp reflex reflector, and the light that fluorescent tube can not be sent reflection fully downwards also in use produces the problem of dazzle.
In order to address the above problem, the utility model provides a kind of reflex reflector that is used for Down lamp, comprises reflection shield and light-emitting window, and described light-emitting window upper limb engages with described reflection shield lower edge; The bore of described light-emitting window from upper limb to lower edge is gradually wide; And on same longitudinal section, the angle of described reflection shield and light-emitting window is the obtuse angle.
Compared with prior art, use the utility model, by the setting of reflection shield and light-emitting window, can effectively enlarge effective direct projection scope of Down lamp, and improve the illuminance under the fluorescent tube, the service efficiency of fluorescent tube greatly improves; Some fins are set on the reflection shield inwall simultaneously, fluorescent tube can be sent most light reflects downwards, fluorescent tube can be sent most light reflects downwards, improve the service efficiency of whole Down lamp, avoided the generation dazzle simultaneously, prevented to dazzle the polished bard order,, improved user's satisfaction for the user brings good experience.

The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the longitudinal profile schematic diagram of reflex reflector of the present utility model, and the reflex reflector that is used for Down lamp comprises reflection shield Z and light-emitting window K, and described light-emitting window K upper limb engages with described reflection shield Z lower edge; The bore of described light-emitting window K from upper limb to lower edge is gradually wide; And on same longitudinal section, the angle of described reflection shield Z and light-emitting window K is obtuse angle P.
Can find by observing, for Down lamp, the light that fluorescent tube sends can direct irradiation to sensitive surface, and this sensitive surface has formed a unlimited in theory circular flat that extends.But the working face that people need can not be a unlimited circular flat that extends, and the plane that the general light that just sends under fluorescent tube can shine directly into gets final product, and can be referred to as working face.Therefore, for the design of Down lamp, should guarantee simultaneously, the light that exists in other scopes should be brought to as far as possible in this scope effectively not blocking in the direct projection scope, irradiation is to working face as far as possible.
According to actual measurement, gradually wide by the bore that light-emitting window and light-emitting window shape be set to from upper limb to lower edge is set, can effectively enlarge effective direct projection scope of Down lamp, and improve the illuminance under the fluorescent tube, the service efficiency of fluorescent tube greatly improves.
Fig. 2 is the longitudinal profile schematic diagram of reflection shield of the present utility model, and reflection shield Z is trumpet type, and the bore from upper limb to lower edge is gradually wide, and such shape helps the light that fluorescent tube sends is reflected downwards more.
As shown in Figure 3, be formed with some fin W on the reflection shield inwall, and on same cross section, the beeline between the adjacent lugs W is greater than the height of projection of described fin W.
As shown in Figure 4, according to actual measurement, many fin W that are provided with on reflection shield Z inwall can send fluorescent tube D most light and reflect downwards, make the service efficiency of whole Down lamp T greatly improve.And on same cross section, beeline between the described adjacent lugs W is greater than the height of projection of described fin W, the most of light reflection that can farthest fluorescent tube D be sent like this downwards, and the light that fluorescent tube D is sent only can not reflect light downwards in the reflection shield internal reflection, avoid the generation dazzle, prevented to dazzle the polished bard order.
According to actual measurement, the height of projection preferred color of choice of fin is set to greater than 2mm, and the most of light reflection that could effectively fluorescent tube be sent like this downwards.
Preferably, described fin can be the right angle rib.Further, described fin can be isosceles right angle rib.By adjusting the shape of fin on the reflection shield inwall, can adjust the angle and the luminous flux that reflect downward light through the fin of reflection shield, accomplish that different irradiated areas adapts, to mix more suitable distribution curve flux.
Described fin passes through along the reflection shield inwall and extends to form;
As shown in Figure 5, described fin W is along oblique the extending to form of reflection shield Z inwall.By the oblique fin on the reflection shield inwall, the most of light reflection that can more fluorescent tube be sent downwards, and if be horizontal fin, stopped that then light reflects downwards.And can change the angle and the luminous flux of the downward light of reflection by adjusting the oblique angle of fin, accomplish that different irradiated areas adapts, to mix more suitable distribution curve flux.Preferably, described fin extends to form along oblique 45 degree of reflection shield inwall.
Described reflection shield inwall is formed by the white reflection material, and the white reflection material can strengthen reflector efficiency, and the utility model does not limit this.
In the utility model, the fin surface is formed by the white reflection material, can be set to different reflectorized materials with the surface of other parts of reflection shield inwall in the fin surface; Wherein, the reflecting rate of the reflectorized material on fin surface is greater than the reflecting rate of the reflectorized material on the surface of other parts of reflection shield inwall.Because the cost of high reflecting rate material is higher than the material (for example the material of common reflecting rate is corrosion resistant plate or aluminium sheet etc.) of common reflecting rate, so only the fin surface is set to high reflecting rate material (white reflection material), and the surface of other parts of reflection shield inwall is set to the material of common reflecting rate, the reflector efficiency of loss can be very little, and reduced cost significantly, improved the market competitiveness of light fixture.
The above; it only is the preferable specific embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with the people of this technology in the disclosed technical scope of the utility model; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
