Description

Technical Field

[0001] The utility model relates to the technical field of lighting lamps, in particular to a shoplight lamp with high light efficiency and low glare. Background Art

[0002] Shoplight (line light or strip light) lamps usually use LED as light source, and are mainly used for lighting needs in shops, supermarkets, offices, workshops and other places, requiring high light efficiency and energy-saving performance.

[0003] At present, many strip lamps on the market that meet the glare value requirements are mostly made using the following two solutions:

[0004] First, it is realized by using an external grille structure;

[0005] Second, use a single-layer prism plate or a diffuser plate plus a prism plate (double-layer plate) to achieve the glare value.

[0006] The structures of these two methods on the market have the following disadvantages:

[0007] 1. For the external grille structure, the luminous angle is reduced due to the shading of the grille, which can meet the glare value requirement (UGR<19), but because part of the light is blocked, causing light loss, the luminous efficiency is relatively low, and it is difficult to achieve more than 135LM / W;

[0008] 2. Although the prismatic panel structure can improve the luminous efficiency and meet the 135LM / W requirement, the light control angle is insufficient and the glare value is difficult to reduce. Generally, UGR < 22 can be achieved, but it is difficult to achieve UGR < 19. Utility Model Content

[0009] The utility model aims to provide a shoplight with high light efficiency and low glare, so as to solve the technical problem that the light efficiency and glare value of existing line lights cannot be taken into account at the same time.

[0010] To achieve the above-mentioned purpose, the utility model provides a shoplight lamp with high lighting efficiency and low glare, comprising a through-groove-shaped heat dissipation bracket, a light source board is installed in the heat dissipation bracket, an LED for emitting light is installed on the light source board, a lampshade is installed above the heat dissipation bracket, plugs for fastening the heat dissipation bracket and the lampshade are installed at both ends of the lamp, a lens plate is installed above the light source board, the lens plate comprises a rectangular plate body, the long sides of the plate body extend in the upward and downward directions to form side walls, the plate body is recessed upward to form a concave spherical surface corresponding to the LED on its bottom surface, and a convex spherical surface corresponding to the concave spherical surface is formed on the top surface of the plate body, the concave spherical surface and the convex spherical surface constitute a light-controlling angle lens; the lampshade is provided with a microlens structure to form a prismatic lampshade.

[0011] Optimize light control. By installing a lens plate inside the lamp, the light-emitting angle of the LED can be adjusted and optimized to form a light-control angle lens. This can effectively control the scattering direction and angle of the light and improve the focus and utilization efficiency of the light beam.

[0012] Improve light efficiency. The design of the lens plate can not only control the divergence range of light, but also reduce light loss in non-target areas, thereby improving the overall light efficiency of the lamp. In this way, the lamp can provide higher lighting brightness with lower power, achieving energy-saving and environmental protection effects.

[0013] To improve the uniformity of light, the lampshade adopts a micro-lens structure to form a prismatic lampshade, which can make the light more evenly scattered and distributed in the process of passing through the lampshade, reduce the focus and unevenness of light, and improve the uniformity, softness and comfort of the lighting effect.

[0014] It can be seen that this design can effectively optimize light control, improve light efficiency, and improve the uniformity of lighting effects, providing users with a more comfortable and efficient lighting experience.

[0015] Preferably, the light source plate and the lens plate are respectively provided with corresponding fixing holes, and the light source plate and the lens plate are fixed together to the heat dissipation bracket by fixing screws.

[0016] Through the design of fixing holes and screws, the light source board and the lens board can be firmly fixed on the heat dissipation bracket to ensure the stability and safety of the lamp.

[0017] As an important heat dissipation component, the heat dissipation bracket can effectively conduct and dissipate the heat generated inside the lamp to the external environment. By fixing the light source board and the lens board on the heat dissipation bracket, the heat dissipation effect of the heat dissipation bracket can be better utilized, the operating temperature of the lamp can be kept within a suitable range, and the service life of the lamp can be extended.

[0018] The setting of fixing holes and screws makes the installation of light source board and lens board easier and faster. Just align them with the fixing holes and fix them with screws, which saves complicated installation steps and improves installation efficiency.

[0019] If the lamp needs maintenance or parts replacement, just unscrew the fixing screws to remove the light source board and lens board, which is convenient for maintenance and replacement, saving maintenance costs and time.

[0020] It can be seen that the design of separately setting fixing holes and fixing them to the heat dissipation bracket through fixing screws improves the stability and heat dissipation effect of the lamp, simplifies the installation process, and facilitates maintenance, which is an effective design solution.

[0021] Preferably, a power board is provided, and the power board is installed in a plastic box. A metal power box is provided outside the plastic box and is installed on the heat dissipation bracket by fixing screws.

[0022] Placing the circuit in a plastic box can prevent the circuit from being affected by the external environment, such as moisture, dust, etc., thereby extending the service life of the circuit and improving the reliability of the lamp.

[0023] By fixing the metal power supply box on the heat dissipation bracket, the overall stability and safety of the lamp are further enhanced.

[0024] By connecting the metal power box with the heat dissipation bracket, the metal power box can be used as a heat sink to effectively dissipate the heat generated by the power supply components, thereby improving the overall heat dissipation effect, helping to keep the operating temperature of the lamp within a suitable range, and extending the service life of the lamp.

[0025] Furthermore, the heat dissipation bracket is formed by sheet metal stamping, and its interior is sprayed with white paint or white powder for increasing reflectivity.

[0026] The heat dissipation bracket formed by sheet metal stamping has a large surface area and good heat dissipation performance, which can effectively conduct the heat generated inside the lamp to the bracket surface and quickly dissipate it into the surrounding environment.

[0027] The spray coating of white paint or white powder has a high light reflectivity, which can make more light inside the heat dissipation bracket be reflected, reducing light loss and energy waste. In this way, the light efficiency of the lamp is improved, and users can get higher lighting brightness at lower power, achieving energy-saving and environmental protection effects.

[0028] Improve light uniformity. The surface of white paint or white powder has a more uniform reflective property, which can make the light reflect and scatter more evenly inside the bracket, reduce the focus and unevenness of the light, improve the uniformity and comfort of the lighting effect, and enhance the user experience.

[0029] It can be seen that spraying white paint or white powder inside the heat dissipation bracket formed by sheet metal stamping can improve the heat dissipation efficiency, light efficiency and light uniformity.

[0030] The utility model provides a shoplight lamp with high light efficiency and low glare, which has the following advantages:

[0031] Compared with the existing technology, a light control angle lens plate is added inside the lamp to change the LED light emitting angle to about 80 degrees (average 50% beam angle). The light outside the light distribution angle of ±40 degrees is reduced, so that most of the light is emitted within ±40 degrees, which reduces light loss and achieves high light efficiency. By combining a lens plate with a light control angle lens and a prism lampshade, the lens plate reduces the light emitting angle of the LED, and the prism lampshade further increases the light emitting angle. The prism lampshade also softens the light, thereby achieving the purpose of meeting high light efficiency and low glare value. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0036] See also Figure 1 and Figure 2 The utility model provides a shoplight lamp with high light efficiency and low glare, including a through-groove-shaped heat dissipation bracket 90, a light source board 70 is installed in the heat dissipation bracket 90, a lens board 60 is installed above the light source board 70, a prism lampshade 10 is installed above the heat dissipation bracket 90, and plugs 80 for fastening the heat dissipation bracket 90 and the prism lampshade 10 are installed at both ends of the lamp.

[0037] The light source board 70 and the lens board 60 are respectively provided with corresponding fixing holes. The light source board 70 and the lens board 60 are put into the heat dissipation bracket 90 together, and the light source board 70 and the lens board 60 are fixed together in the heat dissipation bracket 90 by fixing screws 50.

[0038] A power board 40 is also provided, and the power board 40 is installed in the plastic box 30. A metal power box 20 is provided outside the plastic box 30 to assemble into a complete driving power supply. The assembled driving power supply is installed on the heat dissipation bracket 90 by fixing screws.

[0039] The heat dissipation bracket 90 is formed by sheet metal stamping, integrating a heat sink and a fixing bracket, and is sprayed with white paint or white powder inside to increase reflectivity; the prism lampshade 10 adopts a microlens structure.

[0040] The heat dissipation bracket 90 formed by sheet metal stamping has a large surface area and good heat dissipation performance, and can effectively conduct the heat generated inside the lamp to the bracket surface and quickly dissipate it into the surrounding environment.

[0041] The spray coating of white paint or white powder has a high light reflectivity, which can make more light inside the heat dissipation bracket 90 be reflected, reducing light loss and energy waste. In this way, the light efficiency of the lamp is improved, and the user can obtain higher lighting brightness at lower power, achieving energy-saving and environmental protection effects.

[0042] Improve light uniformity. The surface of white paint or white powder has a more uniform reflective property, which can make the light reflect and scatter more evenly inside the bracket, reduce the focus and unevenness of the light, improve the uniformity and comfort of the lighting effect, and enhance the user experience.

[0043] It can be seen that the heat dissipation bracket 90 formed by sheet metal stamping is sprayed with white paint or white powder inside, which can improve the heat dissipation efficiency, light efficiency and light uniformity.

[0044] The lens plate 60 includes a rectangular plate body, the long sides of the plate body extend in the upward and downward directions to form side walls, the plate body is recessed upward to form a concave spherical surface corresponding to the LED on the bottom surface, and a convex spherical surface is formed on the top surface of the plate body. The concave spherical surface and the convex spherical surface constitute a light control angle lens, which reduces the light emission angle of the LED from the previous 120 degrees to 80 degrees, and reduces the light outside ±40 degrees through the light control angle lens. A prism lampshade 10 is added outside to further control the light, further reduce the angle of the LED to 70 degrees, and soften the light emitted to the lampshade before emitting it, thereby further achieving the purpose of reducing the glare value.

[0045] The light control lens 60 reduces the light outside ±40 degrees and reduces the light irradiating the sides and ends, thereby reducing the loss of luminous flux and achieving the purpose of high flux and high light efficiency, thus meeting the energy efficiency requirements of DLC (light efficiency reaches more than 135LM / W, glare value UGR<19).

[0046] Optimize light control, by installing a lens plate 60 inside the lamp, the light-emitting angle of the LED can be adjusted and optimized to form a light-controlling angle lens. This can effectively control the scattering direction and angle of the light, and improve the focusing degree and utilization efficiency of the light beam.

[0047] Improve light efficiency: The design of the lens plate 60 can not only control the divergence range of light, but also reduce light loss in non-target areas, thereby improving the light efficiency of the entire lamp. In this way, the lamp can provide higher lighting brightness with lower power, achieving energy-saving and environmental protection effects.

[0048] To improve the uniformity of light, the lampshade adopts a microlens structure to form a prismatic lampshade 10, which can make the light more evenly scattered and distributed in the process of passing through the lampshade, reduce the focus and unevenness of the light, and improve the uniformity, softness and comfort of the lighting effect.

[0049] It can be seen that this design can effectively optimize light control, improve light efficiency, and improve the uniformity of lighting effects, providing users with a more comfortable and efficient lighting experience.

[0050] The utility model provides a shoplight lamp with high light efficiency and low glare, which has the following advantages:

[0051] By combining a lens plate with a light-controlling angle lens and a prism lampshade, the lens plate reduces the light-emitting angle of the LED, the prism lampshade further increases the light-emitting angle, and the prism lampshade softens the light at the same time, thereby achieving the purpose of high light efficiency and low glare value.
