Description

Reflection shade capable of adjusting tearing position and lamp

Technical Field

The utility model relates to the technical field of reflectors and lamps, in particular to a reflector and a lamp with an adjustable tearing position.

Background

White light LEDs have become the mainstream illumination source by virtue of high light efficiency, long lifetime, no pollution, and the like. For street lamps with glass, light emitted by the LED light source is distributed through the lens and then penetrates through the glass, so that the effect of road illumination is achieved.

However, after the light emitted by the LED light source passes through the lens, a part of the light with a large angle is blocked and absorbed by the structural member of the lamp, and another part of the light is reflected, absorbed and transmitted on the surface of the glass. When the transmitted light is refracted from the glass to the air, the light having a partial refraction angle greater than the critical angle is totally reflected. The structural member blocks the light absorbed by the whole lamp and the light absorbed, reflected and totally reflected by the glass is the light lost by the lamp. Thus reducing losses in this part and allowing them to refract away is one way to increase the efficiency of the luminaire.

Currently, in order to reduce the loss of the above parts, it is a conventional practice to increase the transmittance of glass, for example, to use ar coated glass, to reduce the light reflected on the surface of glass, thereby increasing the efficiency of the lamp, but coated glass is expensive to manufacture and cannot compensate for the loss of luminous flux caused by total reflection. The other is to use a reflector to reflect the light absorbed by the structural member and the light totally reflected on the glass into light with a small angle by the reflector, and reflect the reflected light again, thereby increasing the efficiency of the lamp. However, when the reflector is used, different lamp panels may have different terminal positions, so that the suitability of the reflector is greatly affected. And if the position of the opening is large enough, the area of the reflecting cover which can reflect light can be reduced, and the efficiency of the lamp is improved on a higher level by affecting the reflecting cover.

Therefore, there is a need for a reflector and a lamp with an adjustable tear position, which further solve the problem that the reflector is suitable for different lamp panels while maintaining good lamp efficiency.

In other embodiments, the number of the tearing openings 31 may be two or more, and the width of each tearing opening 31 is slightly larger than the width of the terminal, so that only the tearing opening 31 at the corresponding terminal position needs to be torn.

In some embodiments, the first opening encloses the LED light beads 80 on the light panel 2.

Specifically, the main body of the reflector 1 with the tearing position adjustable is square horn-shaped. The back of the lamp panel 2 of the lamp is covered with radiating fins, the lamp panel 2 is respectively connected with one end of the first reflecting plate 10, the second reflecting plate 20, the third reflecting plate 30 and the fourth reflecting plate 40, and the four reflecting plates enclose the LED lamp beads 80 arranged at one end of the lamp panel 2 far away from the radiating fins.

In some embodiments, the tear 31 is formed by spaced apart through holes. The spaced through holes are arranged in a regular pattern to form a punctiform tear line that encloses a dimension slightly greater than the terminal 90. In use, the point-like tear lines corresponding to the specific location of the terminal 90 may be pressed according to the location, and the point-like tear lines may be torn by being integrally connected under the action of the pressing force. In this embodiment, the through holes may be arranged in a wavy, zigzag or circular arc shape, so long as they are finally enclosed to form a dot-shaped tear line slightly larger than the terminal 90.

In some embodiments, the tear 31 is comprised of an indentation or cut. The indentations or cuts are enclosed as punctiform tear lines of slightly larger size than the terminals 90. In use, the point-like tear lines corresponding to the specific location of the terminal 90 may be pressed according to the location, and these point-like tear lines may be torn apart by the pressing force. In the present embodiment, the thickness at the indentation or the cut is much smaller than the overall average thickness of the first, second, third and fourth reflection plates 10, 20, 30 and 40.

In some embodiments, the end surfaces of the first, second, third and fourth reflection plates 10, 20, 30 and 40 corresponding to one side of the lamp panel 2 are coated with a reflective coating or attached with a reflective sticker. Thus, the light emitted from the lamp panel 2 can be reflected by the refraction of the first reflecting plate 10, the second reflecting plate 20, the third reflecting plate 30 and the fourth reflecting plate 40. In this embodiment, the tear 31 is also sealed and also coated with a reflective coating or affixed with a reflective sticker.

In some embodiments, the area surrounded by the tearing opening 31 is formed by paper, the first reflecting plate 10, the second reflecting plate 20, the third reflecting plate 30 and the fourth reflecting plate 40 are formed by plastic except the area corresponding to the tearing opening 31. In use, the paper tear 31 corresponding to a specific location of the terminal 90 may be pressed, and the paper tear 31 may be ruptured by the pressing force.

In some embodiments, the included angle between one of the first reflecting plate 10, the second reflecting plate 20, the third reflecting plate 30 and the fourth reflecting plate 40 and the plane of the lamp panel 2 is greater than or equal to 60 degrees and less than or equal to 90 degrees (the included angle between the reflecting plate and the lamp panel 2 is greater than 90 degrees), and the included angles between the remaining three reflecting plates and the plane of the lamp panel 2 are less than or equal to 30 degrees (the included angles between the reflecting plates and the lamp panel 2 are all greater than 90 degrees). That is, the four reflection plates are flared outwards. Referring to fig. 2 and 3, angle 1, angle 2 and angle 3 are all less than or equal to 30 degrees, and angle 4 is more than or equal to 60 degrees and less than or equal to 90 degrees.

Referring to fig. 4 again, the light emitted from the lamp panel 2 with a large angle is emitted out of the lamp after being reflected by the reflective coating or the reflective sticker on the first, second, third and fourth reflective plates 10, 20, 30 and 40, thereby improving the efficiency of the lamp.

In some embodiments, the connection portion 50 between the first reflecting plate 10, the second reflecting plate 20, the third reflecting plate 30 and the fourth reflecting plate 40 is an elastic member, and may specifically be an elastic film, and the elastic film is also covered with a reflective coating or a reflective sticker. The first, second, third and fourth reflection plates 10, 20, 30 and 40 may rotate around four sides of the base 70. In this way, the user can adjust the included angles between the first reflecting plate 10, the second reflecting plate 20, the third reflecting plate 30, the fourth reflecting plate 40 and the lamp panel 2 according to the specific use scene, the brightness of the lamp panel 2, the height of the lamp beads and other parameters, and then lock the lamp panels. And in the process of adjusting the angle, the elastic film can stretch to be larger or smaller. Therefore, the reflector 1 can adapt to a plurality of lamps, and meanwhile, the reflecting plate can be adjusted to an optimal reflecting angle, so that the efficiency of the lamps is ensured to the greatest extent.

According to the reflector with the adjustable tearing positions, the two tearing openings 31 are formed in the reflecting plates corresponding to the terminals 90 in the first reflecting plate 10, the second reflecting plate 20, the third reflecting plate 30 and the fourth reflecting plate 40, so that the corresponding tearing openings 31 can be torn according to the positions of different terminals 90, and the reflector 1 is applicable to different lamp panels 2 and meanwhile the luminous efficiency of a lamp is guaranteed. By providing the tear 31 in the different configurations described above, the tear 31 is more easily torn. By arranging the reflective coating or the reflective sticker on the first reflective plate 10, the second reflective plate 20, the third reflective plate 30 and the fourth reflective plate 40, the reflective efficiency is further improved, and the efficiency of the lamp is further improved. And the angles 1, 2 and 3 are all less than or equal to 30 degrees, so that the light with a large angle can be reflected out as much as possible without affecting the polarized light of the lens, the angle 4 is more than or equal to 60 degrees and less than or equal to 90 degrees, and the light refracted to the rear of the lamp by the lens can be reflected to the front of the lamp as much as possible. The silk screened glass 60 can conceal the terminals 90, making the light fixture more aesthetically pleasing.
