Description
Technical field
The utility model relates to a kind of light fitting reflecting cover, particularly relates to a kind of energy-conservation reflection shield of optics that is applicable to highly effective gas-discharge lamp.
Background technology
Use the light fixture of conventional light source structurally how to form at present by reflector and cloche, the light portion that light source sends directly transmits cloche and arrives the road surface, another part penetrates through cloche after reflecting through reflector again, generally the light via the reflector reflection accounts for 60% of light source total light flux, and this type of reflector adopts aluminium panels to be stamped to form usually, reflective surface is single globoidal structure more, and causing its reflectivity is 50%-60%, and the overall light extraction efficiency of light fixture is only about 70%.And because light source is positioned at paraboloidal focus place in the installation site of reflection shield, make the light fixture dark low circular light spot of luminance uniformity in bright periphery, center of on illuminated road, breaking forth, the index that the center brightness of hot spot often requires far above national road illumination standards causes the waste of energy, and road is the strip zone of prolonging longitudinal extension, in order to reach the requirement of the road surface brightness and the uniformity, most of peripheral light of circular illumination hot spot all will be fallen the secondary waste that causes light outside the effective lighting zone.Comprehensive above explanation, the useful luminous flux utilization rate less than 50% of conventional lamp.
The utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, a kind of light efficiency utilization rate height is provided, is applicable to the energy-conservation reflection shield of the optics that is used for highly effective gas-discharge lamp of general modification scheme.
The technical scheme that the utility model adopted is: the utility model comprises the body of cover cap shape, this body has convex surface and as the concave surface of reflective surface, it is characterized in that: described concave surface is made up of the parabola reflecting surface of several cardinal principle quadrangularlies, improve the light efficiency utilization rate, reduced the light loss consumption to greatest extent.
Further, the parabolic surface in the middle of described concave surface comprises and the side cambered surface of both sides, the light part that the gas-discharge lamp lamp that is positioned at the reflection shield center is sent directly penetrates by direct projection, the light of light source directive mid portion reflects through the reflective surface of parabolic surface, and a part of scattering is penetrated via the side arc reflective surface reflection back of two sides in the light of side.
Further, described parabolic surface and bottom surface form 50 degree angles.
Further, be provided with the installing hole that perpendicular light source is installed at described parabolic surface center.
Further, the parabolic surface in the middle of described convex surface comprises and the side cambered surface of both sides.
Further, be provided with light source fixing frame at described convex surface center.
Further, be provided with the flange platform, on four jiaos of described flange platform, be symmetrically arranged with fixedly connected post, in modification scheme, be convenient to install in the bottom surface of described body.
Further, described flange platform and concave surface are provided with seal groove along the intersection in week.
Further, described body adopts alumin(i)um zinc alloy or resistant to elevated temperatures synthetic resin die casting to form.
The beneficial effects of the utility model are: because concave surface of the present utility model is made up of the parabola reflecting surface of several cardinal principle quadrangularlies, the indent light-emitting area that the light that is sent by perpendicular light source is combined by several little parabolas reflects and goes out, its light reflectance is up to more than 95%, just as in reflective surface, there being several small light sources to shine jointly, having improved light efficiency greatly, is more than 3 times of common reflection shield.Its output light flux of empirical tests can increase more than 60%, promptly for road lighting under same illumination requirement, actual input power can be reduced to 50% of present input power, has reduced energy consumption and energy cost significantly.
In addition, the energy-conservation reflection shield of optics of the present utility model install aspect the transformation very convenient and have certain versatility.When carrying out reducing energy consumption, the actual at present street lamp that uses normally whole light fixture is all replaced, caused great waste like this, also increased simultaneously the input cost of reducing energy consumption, adopt the utility model reflection shield instrument to need original street lamp reflecting shade is removed, fixedly connected according to plate and the utility model reflection shield four of being connected and fixed that it is suitable that former street lamp inner cover profile is sheared processing that post is fixedly connected to get final product.
