Description

Double-layer multi-faceted reflective cup and flashlight and lamp with the reflective cup

technical field

The utility model relates to a reflective cup with functions of reflecting light and concentrating light, as well as a flashlight and a lamp with the reflective cup.

Background technique

Flashlight is a lighting device commonly used in people's daily life and work. The reflector used in common flashlights consists of a paraboloid and a luminous body located at the center of the focal point of the paraboloid. As light-emitting diodes are used more and more widely in lighting, the bulbs in flashlights are gradually replaced by light-emitting diodes with advantages such as energy saving and durability; due to the limited brightness of single light-emitting diodes, a flashlight usually needs to use multiple light-emitting diodes , the traditional reflective cup composed of a paraboloid can no longer meet the requirements of use.

Utility model content

The primary purpose of the utility model is to provide a double-layer multi-faceted reflective cup which is suitable for multiple illuminants and has good light-gathering and reflective effects. The further purpose of the utility model is to provide a flashlight and a lamp with the double-layer multi-faceted reflective cup.

In order to achieve the above-mentioned primary purpose, the utility model adopts the following technical scheme: the double-layer multi-faceted reflector cup includes a reflector and a luminous body, and the reflector is composed of an outer reflector and an inner reflector; the outer reflector is composed of multiple It is formed by connecting two paraboloids. At the focal point of each paraboloid, there are fixed laterally arranged outer illuminants. The light emitted by each outer illuminant is reflected by the corresponding paraboloids and then emitted in a forward direction to form an outer halo; the outer reflector There is an inner reflector formed by an independent paraboloid on the inner axis, and a positive inner luminous body is fixed at the focal point of the inner reflector. The light emitted by the inner luminous body is reflected by the inner reflector and emitted forward. , forming a beam of inner beams located in the middle of the outer halo; the combination of the outer halo and the inner beams forms a uniform and complete circular beam.

As a preferred solution, the outer reflector is formed by connecting three to six paraboloids.

The inner and outer light emitters are preferably light emitting diodes. Of course, the illuminant can also be a light bulb.

A new type of flashlight can be formed by installing the double-layer multi-face reflective cup of the utility model on the flashlight instead of the existing reflective cup.

A new type of lamp can be formed by installing the double-layer multi-face reflective cup of the utility model on the lamp instead of the existing reflective cup.

In the double-layer multi-faceted reflective cup of the present utility model, a plurality of outer luminous bodies on the outer layer are horizontally arranged to irradiate directly to respective corresponding paraboloids on the outer layer reflector, and the light within the effective luminous angle range of each outer luminous body falls on the corresponding paraboloids. Inside, all are reflected and emitted in a positive direction, forming an outer halo with greater light intensity, which effectively utilizes the characteristics of greater luminous intensity on the central axis within the viewing angle range of the outer luminous body, and doubles the light intensity of the traditional reflective form above. The light emitted by the inner luminous body is condensed by the inner reflector to form a circular light column, which is emitted forward and falls into the center of the outer light ring, so that the condensed light of the outer reflector is more round, solid and uniform. Since the light intensity in the middle of the outer halo is formed by the reflected light from the inner and outer illuminants, its intensity is particularly large, and its visual distance can be improved when it is used for long-distance irradiation.

The utility model is a novel flashlight composed of double-layer multi-faceted reflective cups mounted on the flashlight, which has good light-gathering effect, strong light, energy saving, and is more beautiful and economical to use. Equally, the double-layer multi-faceted reflective cup of the present utility model also can be contained on other lamps and forms novel lamps and lanterns.

Detailed ways

The specific embodiment of the utility model will be further described below in conjunction with the accompanying drawings.

As shown in Figure 1, the reflector cup of the present utility model is made up of outer layer reflector 1, inner layer reflector 2 and inner and outer light-emitting diode light-emitting body 3 ", 3 '. Outer layer reflector 1 is connected by three paraboloids. The focal point of each paraboloid has its own light-emitting diode (i.e., the outer luminous body 3') arranged horizontally, and the light emitted by each outer luminous body 3' is reflected by the corresponding paraboloid to form a beam of parallel light that is emitted forward , the light path is shown by the arrow in Figure 2. The parallel light formed by each outer luminous body 3' constitutes an outer halo. On the inner side of the outer reflector 1, there is an inner reflector 2, which is an independent and complete paraboloid , at the focal point of the parabola is a light-emitting diode (i.e. inner luminous body 3") arranged in a forward direction, and the light emitted by the inner luminous body 3" is reflected by the inner reflector 2 to form a beam of parallel beams and emit forward , falling on the center of the outer halo formed by the outer reflector 3', which improves the light-gathering and reflecting effect of the entire reflector cup. The combination of the outer halo and the inner beam forms a uniform and complete circular light beam with a large area of light intensity.

As shown in Figure 3, the reflector is also composed of an outer reflector 1, an inner reflector 2, and inner and outer illuminants 3', 3". The difference is that the outer reflector 1 is connected by four paraboloids .

Of course, the outer reflector 1 can be formed by connecting five, six, seven...etc. multiple paraboloids according to needs.

The utility model adopts the double-layer multi-faceted reflective cup to replace the reflective cup in the existing flashlight, which constitutes a new type of flashlight, which has good light-gathering and reflective effect, saves electric energy and has a long visual distance.

The double-layer multi-faceted reflective cup of the utility model can also be applied to fixed lighting fixtures such as downlights and spotlights, or mobile lighting fixtures such as headlights, bicycle lights, work lights, and camping lights.

The specific implementation described above is a preferred embodiment of the present invention, and cannot limit the claims of the present invention. Any other changes or other equivalent replacement methods that do not deviate from the technical solution of the present invention are included in the present invention. within the scope of protection.
