Description

wide angle light source

technical field

The utility model relates to a light source, in particular to a wide-angle lighting source whose lighting angle is greater than 180 degrees.

Background technique

There are many kinds of light sources such as incandescent lamps, energy-saving lamps, and LED lamps. Among them, incandescent lamps have been replaced by energy-saving lamps because they consume more electricity and have a shorter filament life. However, compared with LED light sources, energy-saving The volume of the lamp is relatively large and the life is relatively short, so the technology of LED light source is developing rapidly. At present, the LED luminous body part of the LED light source is generally designed by plane welding, that is, multiple LED luminous bodies are welded on a flat circuit board to achieve, but the lighting angle of this structure can only reach 180 degrees, compared with incandescent lamps and Energy-saving lamps have certain disadvantages in terms of the lighting angle greater than 180 degrees.

Contents of the invention

The purpose of the utility model is to provide a wide-angle light source, which can greatly increase the lighting angle of the plane luminous body, so as to meet the use requirements of more lighting conditions.

The utility model realizes the above object like this:

The wide-angle light source includes a luminous body assembly and a lampshade, and a light-transmitting reflector cup is installed upside down on the inner surface of the top of the lampshade.

As an improvement of the above technical solution, the lampshade is a housing with a diffuse reflection effect.

As a further improvement of the above technical solution, the reflective cup is a housing with a diffuse reflection effect.

As a further improvement of the above technical solution, the inner surface of the top of the lampshade is provided with a shoulder or a slot that engages with the edge of the reflector cup.

As a further improvement of the above technical solution, the top of the lampshade is provided with a perforation, and the reflector is also provided with a corresponding perforation, and there is a connecting line, one end of which is fixed to the perforation on the top of the cover, and the other end is fixed to the perforation of the reflector. The reflector is fixed on the inner surface of the top of the lampshade through wire connection.

As a further improvement of the above technical solution, the top of the lampshade is open, and the reflector cup is installed upside down at the opening.

As a further improvement of the above technical solution, the lampshade and the reflector cup are integrally formed.

The beneficial effects of the utility model are: part of the light emitted by the illuminant assembly is irradiated to the area in front of the illuminant through the lampshade, and part of the light is reflected and irradiated to the area behind the illuminant when passing through the reflector cup, thus effectively improving The lighting angle of the light source is clearly defined, so as to adapt to the needs of various lighting conditions.

Detailed ways

Referring to FIG. 1 and FIG. 2 , the wide-angle light source includes an illuminant assembly 1 and a lampshade 2 , and a light-transmitting reflector 3 is installed upside down on the inner surface of the lampshade 2 top. Part of the light emitted by the illuminant assembly 1 is irradiated to the area in front of the illuminant through the lampshade 2, and part of the light is reflected and irradiated to the area behind the illuminant when passing through the reflector cup 3, thus effectively improving the illumination of the light source Angle, in order to adapt to the needs of a variety of lighting conditions.

Since illuminants such as LEDs have the characteristics of high brightness in the front and large brightness attenuation in the side, in order to make the brightness of the entire light source more uniform in all directions, the lampshade 2 adopts a shell with a diffuse reflection effect, which can effectively improve The uniformity of illumination across the light source is also softer. In order for the lampshade 2 to have a diffuse reflection effect, suitable plastic injection molding can be selected, and the molded lampshade 2 can also be obtained by frosting.

Similarly, in order to achieve the uniformity of the illumination of the light source, the reflector 3 can also adopt a shell with a diffuse reflection effect.

If the top of the lampshade 2 is arched, it is difficult for the reflector 3 to be integrally formed with the lampshade 2, and it needs to be installed separately. Of course, the installation method can be through gluing, but it will affect the aesthetics, and it is not very convenient. The utility model also provides A variety of structures are used to facilitate the connection between the reflector 3 and the top of the circular arched lampshade 2, one of which is that the top of the lampshade 2 is provided with a perforation, and the reflector 3 is also provided with a corresponding perforation. There is a connecting line 4, one end of which is connected to the The perforation on the top of the cover is fixed, and the other end is fixed to the perforation of the reflector 3. The reflector 3 is fixed on the inner surface of the top of the lampshade 2 through wire wiring. Referring to Figure 4, generally speaking, the connecting wire 4 can be a transparent nylon wire. Does not affect the use effect. Another option is that the inner surface of the top of the lampshade 2 is provided with a shoulder 21 or a slot that engages with the edge of the reflector 3, that is, when the lampshade 2 is formed, the inner surface can be provided with a shoulder 21 or a slot to reflect light. The diameter of the edge of the cup 3 is slightly larger than the diameter of the shoulder 21 or the slot on the inner surface of the lampshade 2. Referring to Fig. 2 and Fig. 3, it is sufficient to firmly snap the reflector 3 into the shoulder 21 or the slot during installation, which is more convenient for installation , and does not affect the use effect at all.

In addition, in order to facilitate the installation of the reflector 3, the top of the lampshade 2 can also be opened, and the reflector 3 is installed upside down at the opening, as shown in Fig. 5 and Fig. 6 . Moreover, this structure can also form the lampshade 2 and the reflector 3 integrally, and the manufacturing process is simpler and easier.
