Description

LED light tube with brightening effect

technical field

The utility model relates to the field of daily necessities, in particular to an LED lamp tube with a light-enhancing effect.

Background technique

Now the traditional incandescent lamps have been banned, and the life of fluorescent tubes is only a few thousand hours. As a new generation of semiconductor light sources, LED light sources have the advantages of high light efficiency, long life, and no pollution, and have been adopted by more and more consumers. loved ones. A good lighting environment without glare, higher light efficiency, etc., have become the key points of market competition.

1>In the current LED lighting industry, in order to solve the glare problem of LED tubes, milky white (frosted) PC lampshades are often used to complete the mixed light, so that the LED tubes emit light more evenly. This solution has the best user experience and is also the most acceptable to users.

2> In order to increase the light efficiency of LED tubes, transparent PC lampshades are used in the industry. The transparent PC lampshades have a high transmittance, allowing about 95% of light to be emitted, which greatly improves the light efficiency of the entire lamp.

But above-mentioned prior art scheme has its major shortcoming:

1> When the milky white (frosted) PC lampshade is used to solve the glare problem, due to the low transmittance of the milky white (frosted) PC lampshade, only about 85% of the light is emitted from the whole lamp, which affects the overall lighting effect of the LED lamp , so that the energy-saving advantages of LED lamps are discounted;

2> When using a transparent PC lampshade to increase the light effect, due to the high transmittance of the transparent PC lampshade, the human eye can see scattered bright LED illuminants, which brings glare problems. The user experience is poor, and the demand in the market is less than that of milky white (frosted) PC lampshades.

It can be seen that the anti-glare of the milky white (frosted) PC lampshade and the high light efficiency of the transparent PC lampshade in the prior art scheme are a pair of contradictions in terms of customer experience, and there is no good solution in the prior art.

Utility model content

The utility model aims at the defect that it is difficult to balance the anti-glare and high light efficiency of the above-mentioned LED light tube in the prior art, and provides an LED light tube with both high light efficiency and anti-glare.

The technical scheme that the utility model solves its technical problem adopts is:

Construct an LED lamp tube with a light-enhancing effect, including a lamp body, a light-transmitting lampshade that is fastened with the lamp body to form a hollow tubular structure, an LED illuminant disposed inside the lamp body, and a light emitting body disposed on the hollow tubular structure The end caps at both ends, the lampshade includes a light-transmitting shell and a light-increasing layer arranged inside the shell, and the light emitted by the illuminant is emitted through the light-enhancing layer and the light-transmitting shell.

Preferably, the light-enhancing layer is an optical film layer formed directly on the inner side of the housing, specifically an optical film layer formed with acrylic resin.

Preferably, the optical film is an optical film with a uniform prism pattern.

Preferably, the light enhancement layer is a light enhancement sheet installed inside the light-transmitting casing.

Preferably, an optical film made of acrylic resin is molded on the brightness enhancement sheet.

Preferably, the optical film is an optical film with a uniform prism pattern.

Preferably, the lamp body is arched, the shell is made of transparent PC material and arched, and the lamp body and the lampshade are combined to form a lamp tube shape.

Preferably, the plurality of LED illuminants are arranged on the side of the lamp body facing the lampshade, between the lampshade and the lamp body.

Preferably, the plurality of LED illuminants are evenly spaced and distributed along the length direction of the lamp body.

Implementing the technical solution of the utility model has at least the following beneficial effects:

It breaks through the bottleneck of high light efficiency and glare-free technology of LED lamps, and greatly reduces glare while using a transparent cover. At the same time, compared with the milky white (frosted) PC lampshade, the light efficiency is at least increased by 7%-10%, and compared with the transparent PC lampshade, the light efficiency is only reduced by 2%-3%.

Description of drawings

The utility model will be further described below in conjunction with accompanying drawing and embodiment, in the accompanying drawing:

Fig. 1 is an exploded view of an LED lamp tube with a light-enhancing effect in a preferred embodiment of the present invention.

Fig. 2 is an exploded view of an LED lamp tube with a light-enhancing effect in another preferred embodiment of the present invention.

Detailed ways

In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation of the utility model is described in detail with reference to the accompanying drawings.

[Example 1]

As shown in FIG. 1 , the LED lamp tube with the effect of increasing brightness provided by this embodiment includes a lamp body 1 , a light-transmitting lampshade 2 , an LED illuminant 3 and an end cover 4 .

The lamp body 1 is arched; the lampshade 2 is also arched, and the two arched structures are buckled together to form a hollow lamp tube structure. End caps 4 are arranged at both ends of the hollow lamp tubular structure, and are used for connecting external power sources. The lamp body 1 , the lampshade 2 and the end cap 4 constitute the basic shape structure of the LED lamp tube of this embodiment.

Several LED illuminants 3 are arranged on the side of the lamp body 1 facing the lampshade 2, between the lampshade 2 and the lamp body 1, and are evenly spaced along the length direction of the lamp body 1, as the light source of the LED lamp tube of this embodiment .

The light-transmitting lampshade 2 includes a shell 21 made of transparent PC material and a light-enhancing sheet 22 arranged inside the shell 21 , and the light emitted by the LED illuminant 3 is emitted through the light-enhancing sheet 22 and the shell 21 .

The brightness enhancement sheet 22 is made of very transparent and elastic PET material, and an optical film with a uniform prism pattern is precisely molded on its surface with acrylic resin. When the light passes through the optical film, the optical film can reflect the unused polarized light outside the viewing angle, and can change the polarization direction of the light, turning the originally discarded light into the available polarized light with a specific polarization direction. The scattered light emitted by the light source passes through the optical film and gathers towards the front direction, so that the entire LED lamp tube emits light uniformly instead of showing scattered light sources. The LED lamp tube has high light efficiency and the glare is reduced.

[Example 2]

As shown in FIG. 2 , the difference between the LED lamp tube with light-enhancing effect provided by this embodiment and the first embodiment is only in the structure of the light-transmitting lampshade.

The transparent lampshade 2 is a shell 21 made of transparent PC material, and an optical film with a uniform prism pattern of acrylic resin material is precisely molded on the inside of the shell 21 .

Understandably, the LED light tube provided in this embodiment has the same effect as the LED light tube provided in Embodiment 1, that is, the LED light tube has high light efficiency and at the same time reduces glare.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various modifications, combinations and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model shall be included within the scope of the claims of the present utility model.
