Description

Technical Field

[0001] This utility model relates to the field of lighting equipment technology, specifically to a high-brightness, low-glare lighting tube. Background Technology

[0002] In the lighting design of commercial venues such as supermarkets and shopping malls, the lighting must not only meet basic lighting needs, but also attract consumers and highlight the product display. In order to clearly display product details and stimulate consumers' desire to buy, high-brightness lighting tubes are often used to illuminate the products.

[0003] However, existing high-brightness fluorescent tubes have significant shortcomings in use. On the one hand, their light concentration is poor, resulting in considerable energy waste; on the other hand, when the intensity of the light tube increases, strong light reflection can easily cause glare, leading to visual discomfort for consumers at certain viewing angles and affecting the shopping experience. Utility Model Content

[0004] This invention provides a high-brightness, low-glare lighting tube that not only has excellent illumination effects but also effectively avoids glare.

[0005] A high-brightness, low-glare lighting tube includes a lamp housing assembly, a light-emitting strip, an optical processing component, and a light guide. The lamp housing assembly has a mounting groove in the middle and a main light outlet at the bottom. A fixed bottom edge and a fixed side edge are formed on the side of the main light outlet. The light-emitting strip includes spaced-apart LED light-emitting units and is inserted into the mounting groove. The optical processing component is inserted into the mounting groove and located below the light-emitting strip. The optical processing component is made of transparent material and includes a mounting section inserted into the mounting groove. The mounting section has spaced-apart lens portions on its lower surface, which are correspondingly arranged with the LED light-emitting units. The light guide includes spaced-apart covers corresponding to the lens portions. The upper opening of the cover is smaller than the lower opening. The lower end of the cover has a skirt, and the upper opening covers the lens portions. A side light outlet is formed between the side wall of the mounting groove and the cover. The skirt is secured to the fixed bottom edge and the fixed side edge.

[0006] Furthermore, the mounting section of the optical processing component extends downwards to below the mounting groove.

[0007] Furthermore, the light-emitting strip is provided with a positioning hole, and the optical processing component is provided with a positioning post, the positioning post being matched with the positioning hole.

[0008] Furthermore, the lower half of the lamp housing assembly is made of a light-transmitting material.

[0009] Furthermore, the optical processing component is provided with a lamp holder, which is correspondingly arranged with the LED light-emitting unit.

[0010] Furthermore, the lower surface of the lamp holder is frosted.

[0011] The technical solution of this utility model has the following technical effects:

[0012] When the LED light-emitting unit is lit, light enters the optical processing component. Some light is emitted from the side light outlet, causing the lower half of the lamp housing assembly to emit auxiliary weak light; most of the light passes through the lens and then through the light guide to achieve concentrated strong light illumination. A single light strip simultaneously achieves auxiliary contour lighting and high-intensity illumination, reducing costs.

[0013] The auxiliary light serves two purposes: firstly, it acts as a visual buffer against high-intensity illumination, reducing glare; secondly, it outlines the tube's shape, enhancing the display effect. By extending the mounting section of the optical components below the mounting groove, the auxiliary light is appropriately strengthened, further reducing the glare index. The optical components, in conjunction with the light guide, effectively control the direction of light propagation. Testing shows that, at the same brightness, the glare index of this tube is below 12, far superior to the approximately 20 of conventional spotlights.

[0014] The positioning holes and positioning posts work together to achieve relative fixation between the light strip and the optical processing components. Setting the positioning posts on the optical processing components can effectively avoid the influence of holes on the optical path.

[0015] Each component adopts a split-type insertion and snap-fit ​​structure. During installation, the light strip, optical components, and light guide are simply inserted into the lamp housing assembly, making installation convenient and reducing production costs. For later maintenance, the light strip, optical components, and light guide can be removed for replacement, facilitating future repairs. Attached Figure Description

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0023] Example:

[0024] A high-brightness, low-glare lighting tube includes a lamp housing assembly 1, a light-emitting strip 2, an optical processing component 3, a light guide 4, and an end 6. The end 6 is engaged with both ends of the lamp housing assembly by claws 61, thereby forming a cavity in the lamp housing assembly 1. The lamp housing assembly 1 has a built-in power driver (not shown) for driving the light-emitting strip 2 to emit light.

[0025] The lamp housing assembly 1 has a mounting groove 11 in the middle, and the mounting groove 11 includes a limiting side 111 for limiting the horizontal movement of the light-emitting strip 2 and the optical processing component 3. The lamp housing assembly 1 has a main light-emitting port 12 at the bottom, and the main light-emitting port 12 has a fixed bottom edge 121 and a fixed side edge 122 on its side.

[0026] The light-emitting strip 2 includes spaced-apart LED light-emitting units 21 and positioning holes 22. The light-emitting strip 2 is inserted into the mounting groove 11. The positioning holes 22 of the light-emitting strip 2 are used to match the positioning posts 33 of the optical processing component 3, thereby achieving horizontal relative fixation between the light-emitting strip 2 and the optical processing component 3. The width of the light-emitting strip 2 matches the mounting groove 11. When the light-emitting strip 2 is installed in the mounting groove 11, the limiting side 111 defines the horizontal position of the light-emitting strip.

[0027] The optical processing component 3 is inserted into the mounting groove 1 and located below the light-emitting strip 2. The optical processing component 3 is made of transparent material and includes a mounting section 31 inserted into the mounting groove 11. The upper surface of the mounting section 31 is provided with spaced lamp-receiving grooves 34. When the positioning post 33 of the optical processing component 3 extends into the positioning hole 22 of the light-emitting strip 2, the LED light-emitting unit 21 of the light-emitting strip 2 is located in the lamp-receiving groove 34. In this embodiment, the lower surface of the lamp-receiving groove 34 is set to a frosted state, which can further increase the anti-glare effect. The lower surface of the mounting section 31 is provided with spaced lens portions 32, which are located below the lamp-receiving groove 34. That is, the lens portions are correspondingly arranged with the LED light-emitting unit 21 to accurately process the light emitted by the LED light-emitting unit 21. The relative positional relationship between the optical processing component 3 and the light-emitting strip 2 is defined by the cooperation of the positioning post 33 and the positioning hole 22. The width of the optical processing component 3 matches the mounting groove. When the optical processing component 3 is set in the mounting groove 11, the limiting side 111 defines the horizontal position of the optical processing component 3. The mounting section 31 of the optical processing component 3 extends downward to below the mounting groove 11, thereby allowing a small portion of light to be emitted from the side of the optical processing component 3, increasing the auxiliary weak light.

[0028] The light guide 4 includes a cover 41 spaced apart, which is correspondingly arranged with the lens part. The upper opening 411 of the cover 41 is smaller than the lower opening 412. The lower end of the cover is provided with a skirt 413. The upper opening 411 covers the lens part 32. The skirt 413 is locked on the fixed bottom edge 121 and the fixed side edge 122. Due to the structural characteristics of the lamp housing assembly 1, the two sides of the main light outlet 12 are free ends. Therefore, it can produce a certain deformation when subjected to force. When the skirt 413 is inserted into the main light outlet 12, the main light outlet 12 expands slightly to both sides, thereby giving the skirt 413 a certain clamping force, thus limiting the light guide 4 in the horizontal and vertical directions. By reasonably setting the height of the light-emitting strip 2, the optical processing component 3 and the light guide 4, the clamping force of the main light outlet on the skirt 413 can be used to limit the position of the light-emitting strip 2, the optical processing component 3 and the light guide 4 in the vertical direction. After the light-emitting strip 2, optical processing component 3, and light guide part 4 are installed into the lamp housing assembly 1, a side light outlet 5 is formed between the side wall of the mounting groove and the cover. Part of the light emitted by the LED light-emitting unit 21 is emitted from the side light outlet 5 and illuminates the lower half of the lamp housing assembly. The lower half of the lamp housing assembly is made of a light-transmitting material, thereby forming an auxiliary weak light in the lower half of the lamp housing assembly.

[0029] Assembly sequence:

[0030] Component assembly: First, align the positioning post 33 of the optical processing component 3 with the positioning hole 22 of the light-emitting strip 2. Then, snap the upper opening 411 of the light guide cover 4 into the lens portion 32 of the optical processing component. Next, align the light-emitting strip with the mounting groove 11 of the lamp housing assembly 1 and insert it. The skirt 413 of the light guide cover 4 moves with the light-emitting strip 2 and inserts into the main light outlet 12. Because the side of the main light outlet 12 has a deformable free edge, the main light outlet 12 expands during the insertion of the skirt 413. After the light guide cover 4 is inserted into the main light outlet 12, the deformation recovery force of the side of the main light outlet 12 squeezes the skirt 413, that is, the fixed bottom edge 121 and the fixed side edge 122 exert a squeezing or supporting force on the skirt 413. This achieves the function of limiting the light guide cover 4.

[0031] Working process: After the power supply module on one side of the lamp housing assembly supplies power, the LED light-emitting unit lights up. The light enters the optical processing component, and part of it is emitted from the side of the horizontal section to form auxiliary light, giving the lower chamber a weak light outline; most of the light is focused by the light-concentrating section and emitted from the light guide part of the light guide cover to form high-intensity concentrated illumination light. The auxiliary light buffers the visual impact of the high-intensity light and effectively reduces glare.

[0032] The technical solution adopted in this embodiment has the following technical effects:

[0033] When the LED light-emitting unit is lit, light enters the optical processing component. Some light is emitted from the side light outlet, causing the lower half of the lamp housing assembly to emit auxiliary weak light; most of the light passes through the lens and then through the light guide to achieve concentrated strong light illumination. A single light strip simultaneously achieves auxiliary contour lighting and high-intensity illumination, reducing costs.

[0034] The auxiliary light serves two purposes: firstly, it acts as a visual buffer against high-intensity illumination, reducing glare; secondly, it outlines the tube's shape, enhancing the display effect. By extending the mounting section of the optical components below the mounting groove, the auxiliary light is appropriately strengthened, further reducing the glare index. The optical components, in conjunction with the light guide, effectively control the direction of light propagation. Testing shows that, at the same brightness, the glare index of this tube is below 12, far superior to the approximately 20 of conventional spotlights.

[0035] The positioning holes and positioning posts work together to achieve relative fixation between the light strip and the optical processing components. Setting the positioning posts on the optical processing components can effectively avoid the influence of holes on the optical path.

[0036] Each component adopts a split-type insertion and snap-fit ​​structure. During installation, the light strip, optical components, and light guide are simply inserted into the lamp housing assembly, making installation convenient and reducing production costs. For later maintenance, the light strip, optical components, and light guide can be removed for replacement, facilitating future repairs.

[0037] This utility model of a high-brightness, low-glare lighting tube ensures high-brightness illumination while significantly reducing glare through optical structure design and auxiliary light buffering, thus improving the lighting experience. It is also easy to assemble and maintain, and has high practical value.
