Abstract

The utility model discloses a light-gathering structure of a lamp, which comprises: a lampshade; an optical unit, the optical unit is arranged at the open end of the lampshade, one surface of the optical unit is surrounded by a light-gathering part formed by a plurality of sawtooth-shaped adjacently arranged parts; and a light-emitting body, the light-emitting body is arranged in the lampshade and corresponds to the other surface of the optical unit. Thus, the divergent light source emitted by the light-emitting body can be totally reflected (refracted) by the light-gathering part of the optical unit, so as to achieve the effect of increasing the illumination brightness.

Description

Concentrating structure of lamps and lanterns

technical field

The utility model relates to a light-gathering structure of a lamp, in particular to a divergent light source emitted by a luminous body, which can be fully reflected (refracted) by the light-gathering part of an optical unit, thereby achieving the effect of increasing the illumination brightness.

Background technique

At present, commonly used lamps are usually composed of a cover body and a luminous body arranged in the lampshade; thereby, the light source of the luminous body can be emitted directly or after being reflected by the cover body to perform required lighting.

Although the above-mentioned customary lamps can provide the required lighting; however, since the lamp is only composed of a lampshade and a luminous body, and there is no structural design on the lampshade for reflecting and concentrating the light source, when it is used as lighting , often due to the irradiation characteristics of the illuminant, the light source scatters around and cannot effectively concentrate the light source, resulting in a weak emitted light source, and there are situations where the light source scatters and cannot be concentratedly irradiated; When needed.

Utility model content

In view of this, the main purpose of this utility model is to provide a light-gathering structure of a lamp, which can make the divergent light source emitted by the luminous body perform total reflection (refraction) by the light-gathering part of the optical unit, so as to increase the illumination. The effect of brightness.

In order to achieve the above purpose, the technical solution of the utility model is realized in the following way: a light-gathering structure of a lamp, which includes:

lampshade;

An optical unit, the optical unit is arranged at the opening end of the lampshade, and one side of the optical unit is surrounded by a plurality of concentrating parts arranged adjacently in a zigzag shape; and

The illuminant is arranged in the lampshade and corresponds to the other surface of the optical unit.

The beneficial effect of adopting the above-mentioned technical solution is: the light-gathering structure of the lamp of the present utility model can make the divergent light source emitted by the luminous body perform total reflection (refraction) by the light-gathering part of the optical unit, so as to increase the illumination brightness effect, and then make the utility model more progressive, more practical, and more in line with the needs of users.

Detailed ways

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

Please refer to FIG. 1 and FIG. 2 , which are respectively a three-dimensional appearance schematic diagram of the light concentrating structure of the lamp in the present invention and a schematic cross-sectional view of the light concentrating structure of the lamp in the present invention. As shown in FIGS. 1 and 2 , a light concentrating structure of a lamp of the present invention is at least composed of a lampshade 1 , an optical unit 2 and a luminous body 3 .

The inner surface of the lampshade 1 is provided with a reflective surface 11 .

The optical unit 2 is arranged at the opening end of the lampshade 1, and the optical unit 2 can be a light-transmitting refraction material with a bright surface or a matte surface, and the ring on one side of the optical unit 2 is formed by a plurality of sawtooth adjacently arranged. The light concentrating part 21, and the angle of the apex angle of the light concentrating part 21 is between 90°-140°, and 120° is the optimum angle.

The illuminant 3 is disposed in the lampshade 1 and corresponds to the other surface of the optical unit 2 . The illuminant 3 can be a spiral bulb or an LED. Therefore, the above-mentioned structure constitutes a new light-gathering structure of the lamp.

Please refer to FIG. 3 , which is a schematic diagram of the reflective state of the light-gathering structure of the lamp in the present invention. And refer to Figure 1 and Figure 2, as shown in each figure: when the utility model is in use, the light source 3 emits a light source, so that the light source is directly or through the reflection surface 11 in the lampshade 1 to the direction of the optical unit 2 After the light source is refracted by the light-collecting part 21, it is emitted out of the optical unit 2 in a state of total reflection. The state of (refraction) gathers the light source, so that the brightness of the luminous body 3 can be increased.

The above are only preferred specific embodiments of the present utility model, and are not used to limit the patent scope of the present utility model; all equivalent changes and modifications made by using the patent scope of the utility model and the contents of the specification should still be It belongs to the scope covered by the utility model patent.
