Abstract
The invention relates to a square reflecting shade, which consists of a square bottom surface, four same reflecting surfaces connected at the periphery of the bottom surface and edges arranged on the top ends of the reflecting surfaces; and the bottom surface is reserved with a hole position for an LED light source, wherein each reflecting surface of the reflecting shade is formed by connecting a plurality of strip arc surfaces in the horizontal direction; connecting lines for connecting the arc surfaces are parallel to the bottom surface and are parallel with each other; and the arc surfaces forming the reflecting surface gradually expand from bottom to top, so that the reflecting surface tilts outwards for a certain angle to form a square space of which the bottom is small and the upper opening is large. As the unique design scheme is adopted, the reflecting shade remarkably improves the light effect and the utility rate of luminous energy of an LED lamp, so that the LED lamp with the reflecting shade has uniform light emergence and improves the practicability.
Description
Technical field
The present invention relates to a kind of reflection shield, particularly a kind of LED lamp reflection shield.
Background technology
Along with the enhancing of people's energy-saving and environmental protection consciousness, each state is all developing such as reproducible clean energy resourcies such as solar energy, wind energies energetically.At lighting field, various new light sources are also constantly weeded out the old and bring forth the new, and are widely used.Wherein, LED (light emitting diode) is with advantages such as its low energy consumption, high light efficiency, life-span length and colour rendering are good, by the lighting field that is applied in more and more widely.
Reflection shield is meant light fixture in use, can not impinge upon a kind of reflector that the light on work and the life face reflects to what light source sent, uses reflection shield can improve the light utilization efficiency of light fixture greatly, and Luminaire efficiency is improved greatly.The reflecting rate of reflection shield is except depending on material, and the shape of reflection shield particularly to reflection angle of light etc., has determined the disposal ability of reflection shield to the non-direct light of light source.
At present the R﹠D direction of LED light fixture mainly concentrates on and improves the led light source encapsulation technology, to improve the luminous flux utilization rate and to solve the LED heat dissipation technology, delays aspects such as LED light decay to greatest extent, then sets foot in less for the research of reflection shield.Because the defective and the deficiency of reflection shield design, cause that the LED light fixture light efficiency and the efficiency of light energy utilization are low, uneven illumination even, influenced the illuminating effect of LED light fixture.
Summary of the invention
The objective of the invention is to solve the deficiencies in the prior art, a kind of square reflecting shade is provided, to improve the efficiency of light energy utilization of LED light fixture.
Square reflecting shade of the present invention is to be made of a foursquare bottom surface, the edge that is connected 4 identical reflectings surface around the bottom surface and is arranged on the reflecting surface top, and is reserved with the position, hole that led light source is installed on the bottom surface.Reflection shield of the present invention is characterised in that its reflecting surface, and these reflectings surface are to be connected to form by several strip arc surfaces in horizontal direction, and the connecting line that is used to connect arc surface is parallel to the bottom surface, and is parallel to each other between the connecting line.
The arc surface that is used to form reflecting surface is progressively abducent from bottom to top, and reflecting surface is outward-dipping certain angle thereby make, and it is less to constitute a bottom, the square space that upper opening is big.The inclined degree of reflecting surface is controlled by the angle of intersection between the reflecting surface and bottom surface, and suitable angular range is 100～120 °.
Can directly link together between reflecting surface and the bottom surface, also can link together by a transition plane, the height of transition plane generally is not more than the width of arc surface.
The present invention also is provided with the through wires hole that is communicated with the position, hole in any side of bottom surface, is used to arrange the lead of led light source.
Reflection shield of the present invention has significantly improved the light efficiency and the efficiency of light energy utilization of LED light fixture owing to adopted above-mentioned unique design scheme, makes that the LED light fixture bright dipping of this reflection shield of use is even, has improved the practicality of LED light fixture.
Description of drawings
Fig. 1 is the structural representation of square reflecting shade of the present invention;
Fig. 2 is the front view of Fig. 1;
Fig. 3 is the lateral plan of Fig. 1;
Fig. 4 is the A-A cutaway view of Fig. 3.
The specific embodiment
The present invention is further illustrated below in conjunction with drawings and the specific embodiments.
The structure of square reflecting shade is to be 2, four the identical in structure reflectings surface 4 in foursquare bottom surface by one shown in Fig. 1,2,3,4, and edge 5 compositions.Be reserved with the position, hole 1 that is used to install and fix light source on bottom surface 2,2 the circle that is provided with all around highly is the transition plane 3 of 10mm in the bottom surface, and transition plane 3 is basically perpendicular to bottom surface 2.The lower end of four reflectings surface 4 is connected on the corresponding transition plane 3, and the top of reflecting surface 4 is connected with edge 5.
Reflecting surface 4 be by four be level to strip arc surface 41 connect to form, the longitudinal cross-section of each strip arc surface 41 is a little circular arc, therefore, reflecting surface 4 also can be regarded as by 4 continuous little circular arcs and move horizontally the face that forms.
42 of connecting lines between four arc surfaces 41 are parallel to each other, and are parallel to the progressively outwards expansion from bottom to top of 2, four arc surfaces 41 in bottom surface, and reflecting surface 4 is outward-dipping certain angle thereby make.
As shown in Figure 4, get any one longitudinal section, from top to down, the intersection point between the intersection point at arc surface 41 and edge, four arc surfaces and the intersection point of arc surface and transition plane are followed successively by B, C, D, E, F, and then the terminal B of these little circular arcs, C, D, E, F satisfy equation:
Y＝501.293-54.8147X+1.84842X
2-0.0188928X
3
And the radius of described circular arc BC is 65mm, and the radius of CD is 40mm, and the radius of DE is 82mm, and the radius of EF is 46mm, and the intersection 43 between adjacent two reflectings surface 4 is 112 ° with the angle of bottom surface 2.
As shown in Figure 3, any side in square reflecting shade bottom surface 2 also is provided with the through wires hole 6 that is communicated with position, hole 1.
The structure of square reflecting shade is identical with embodiment 1, just the parameter of arc surface 41 changes: the radius of circular arc BC is 60mm, the radius of CD is 20mm, the radius of DE is 120mm, the radius of EF is 46mm, the height of transition plane 3 is 5mm, and the intersection 43 between adjacent two reflectings surface 4 is 103 ° with the angle of bottom surface 2.
