Abstract
A LED lamp reflector is composed of a reflector bottom surface, a reflection curved surface connected to the reflector bottom surface and a reflector rim arranged on the upper edge of the reflection curved surface. The LED lamp reflector is fixedly mounted on a LED chip subbase through the reflector bottom surface for reflecting the light emitted by the LED chip, the reflection curved surface is a waved cambered surface composed of 24 sets of small cambered surfaces separated by several longitudinal plow grooves uniformly, and the small cambered surfaces are wide gradually from inner to outer. The elongation lines of the longitudinal plow grooves are converged at a point, and an included angle between two neighboring longitudinal plow grooves is 15 DEG. The LED lamp reflector is capable of improving light energy of the whole LED lamp, average illumination on an equidistance receiving surface, and the practicability of the LED lamp. The LED lamp reflector has a good energy-saving effect.
Description
Technical field
The utility model relates to a kind of reflector of light fixture, particularly relates to a kind of LED lamp reflector.
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) with its low energy consumption, high light efficiency, the life-span is long and colour rendering good, advantages such as energy-saving and environmental protection, safety, by more and more widely be applied in lighting field.
Led light source does not have conventional light source to the luminous shortcoming in four sides, the characteristics of luminescence of its high directivity can promote the light extraction efficiency of light fixture, but because present reflector design defective and deficiency, 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.
ZL 200510033295.3 discloses a kind of LED lampshade, and inner circumferential surface is divided into ten halves by several grooves, and the angle of adjacent two grooves is 30 °.The design of this lampshade all increases for the light efficiency of LED light fixture and the efficiency of light energy utilization and irradiation uniformity aspect, but desirable not enough.
Summary of the invention
The purpose of this utility model provides a kind of LED lamp reflector, and this LED lamp reflector can further improve the efficiency of light energy utilization and the uniformity of illuminance of reflector.
LED lamp reflector of the present utility model is to be made of reflector bottom surface, the reflector frame that is connected the reflecting curved surface on the reflector bottom surface and is positioned at the reflecting curved surface upper limb, and be provided with a led chip installing hole in the center of reflector bottom surface, this LED lamp reflector is fixedly mounted on the led chip base by its reflector bottom surface, is used for led chip and goes out reflection of light.
Feature of the present utility model is that described reflecting curved surface is the waveform cambered surface that is made of 24 groups of little cambered surfaces that many longitudinal groove average marks on the curved surface are divided into, and described little cambered surface is widened from inside to outside gradually.The extended line that is positioned at the longitudinal groove on the described reflecting curved surface meets at a bit, and the angle between adjacent two longitudinal grooves is 15 °.
Further, the discontinuous cambered surface stack of multilayer that described 24 groups of little cambered surfaces are separated by some lateral trench constitutes, and every layer little cambered surface area increases gradually.
The utility model LED lamp reflector has improved the light energy of whole LED light fixture owing to adopted technique scheme, equidistantly accepts that average illumination improves on the face, and energy-saving effect is better, has improved the practicality of LED lamp.
Description of drawings
Fig. 1 is the structural representation of the described LED lamp reflector of the utility model embodiment;
Fig. 2 is the A-A cutaway view of Fig. 1;
The specific embodiment
The utility model is further described below in conjunction with drawings and the specific embodiments:
The structure of LED lamp reflector as shown in Figure 1 and Figure 2, constitute by reflector frame 1, reflecting curved surface 2 and reflector bottom surface 3, reflector bottom surface 3 is positioned at the bottom of reflecting curved surface 2, upper limb at reflecting curved surface 2 is provided with reflector frame 1, be provided with led chip installing hole 4 in the center of reflector bottom surface 3, reflector bottom surface 3 is fixedly mounted on the led chip base.
Described reflecting curved surface 2 is by 23 longitudinal grooves 22 and 7 24 * 8 discrete little cambered surfaces 21 formations that lateral trench 23 is separated into of being located on the curved surface, undulate cambered surface.The extended line of longitudinal groove 22 meets at a bit, and the angle between adjacent two longitudinal grooves 22 is 15 °.Little cambered surface 21 is widened from inside to outside gradually.
The light effect that goes out for checking the utility model LED lamp reflector, select the led light source of power 100W, luminous efficiency 801m/w for use, use the LED lamp reflector of present embodiment and the LED lampshade of ZL 200510033295.3 to go out the light effect contrast respectively, the luminous flux that calculates present embodiment LED lamp reflector is 7364.51m, and the luminous flux of ZL 200510033295.3LED lampshade is 7290.31m.This shows that LED lamp reflector of the present utility model is than the LED lampshade efficiency of light energy utilization height of background technology, equidistantly accept average illumination height on the face, can reach better energy-saving effect satisfying under the situation of uniformity of illuminance.
