Abstract
The utility model relates to the technical field of daily illumination appliances, and discloses an integrated reflecting hood. A light source cover is arranged in the middle of a disc, reflecting arc surfaces are arranged on two sides of the light source cover, light regulating blocks are disposed in the middles of two side surfaces of the light source cover and are also connected with the middles of the reflecting arc surfaces, the light source cover, the reflecting arc surfaces and the light regulating blocks are integrally formed on the disc, and light condensation surfaces are disposed at two ends of each reflecting arc surface. The integrated reflecting hood is applied to a lamp, can increase light output rate, leads luminous flux to be higher, avoids glare, light pollution and light loss, leads reflected light to be more concentrated, enlarges the illumination range of the lamp, and avoids ghosting and dark areas, and simplifies manufacturing process flow.
Description
Technical field
The utility model relates to normal lighting articles for use technical field, refers in particular to a kind of integral type reflection shield.
Background technology
At present, in the catoptric system of LED street lamp, generally adopt knockdown reflex reflector, this reflex reflector mainly combines (as shown in Figure 3) by optical reflective disk support 5, specular aluminium reflecting piece 6 and specular aluminium light source cover 7 three parts of mirror face stainless steel, though this type of reflex reflector has certain reflecting effect, but it is a combining structure, and less stable easily lost efficacy, there is bigger gap easily in matching part, make the light output rating not high, and its production process complexity, production efficiency influenced.
Summary of the invention
For addressing the above problem, the utility model provides a kind of light that light fixture is reflected more concentrated, and range of exposures is wideer, and logical light quantity is big, the good and simple integral type reflection shield of manufacturing process of reflecting effect.
For achieving the above object, the utility model adopts following technical scheme to be: the centre at disk body is provided with light source cover, these light source cover both sides are provided with reflective cambered surface, the middle part of described light source cover two sides is provided with the lay the grain piece, this lay the grain piece also is connected in reflective cambered surface middle part, this light source cover, reflective cambered surface and lay the grain piece are all one-body molded on described disk body, and described reflective cambered surface two ends are equipped with caustic surface.
Described light source cover is a trapezoid boss, and its two sides are provided with light hole, and these two sides tilt and symmetry mutually, and the angle of inclination of these two sides is 65 °～75 degree.
The light hole of described light source cover is arranged at lay the grain piece both sides, and light hole relative on the light source cover two sides connects mutually, and this light hole is corresponding each other in the position of two sides.
Described lay the grain piece upper surface is triangular in shape, and these lay the grain piece two sides tilt mutually, and the angle of inclination of these two sides is 65 °～75 degree.
Described reflective cambered surface is wing, and this reflective cambered surface is symmetrical about the light source cover both sides, and the caustic surface at these reflective cambered surface two ends is outward-dipping relatively.
The upper end-face edge of described reflective cambered surface is curved, and the radian of this arc is consistent with the radian of disk body correspondence position, and this reflective cambered surface lower end is connected with the bottom of light source cover, and the upper end width of this reflective cambered surface is greater than its lower end width.
Described disk body ovalize, this disk body edge has extended upward flange.
The beneficial effects of the utility model are: structure integrated, avoided because of the improper situation that exists the gap to influence the output rating of light of parts combination, to such an extent as to avoided needing to make separately the situation that operation influences productivity ratio that increases because of each parts of forming, improved the light output rating, make luminous flux bigger, solve dazzle, and simplified manufacturing process flow; In reflective cambered surface the lay the grain piece is set, inclined-plane, both sides by the lay the grain piece carries out reflective to light source, make reflection ray more concentrated, this lay the grain piece and reflective cambered surface cooperatively interact, avoided light pollution and caused the loss of light because of reflective cambered surface wider range at reflex time, improve the range of exposures of light fixture, avoided the appearance of ghost image and dark space.
