Description

Technical Field

[0001] This utility model relates to the field of electronic clock technology, specifically an energy-saving LED clock. Background Technology

[0002] An LED clock is a device that displays time by emitting light through an LED light source. Compared to traditional electronic clocks, it uses the high brightness of LED light to ensure that the time displayed is clear, making the clock more effective at displaying time.

[0003] However, existing LED clocks still have technical defects. For example, a smart LED clock screen disclosed in Chinese utility model patent document CN220606090U uses a large number of LED light sources to form the time marker pattern. Therefore, the high power consumption of the light sources during operation will affect the battery life of the LED clock. Furthermore, the light intensity emitted by the combination of a large number of LED light sources is relatively high. If the light emitted by the LED light sources is not uniform in direction when it is emitted out of the clock, or if there is excessive light dispersion, the time value displayed on the clock will be unclear. Moreover, the user's eyes are easily damaged by the strong light during use, which affects the user's experience. Utility Model Content

[0004] To address the technical deficiencies in the background technology, this utility model proposes an energy-saving LED clock, which solves the aforementioned technical problems and meets practical needs. The specific technical solution is as follows:

[0005] An energy-saving LED clock includes a housing and a PCB, wherein the PCB is fixedly connected inside the housing and electrically connected to a plurality of control buttons on one side wall of the housing, and further includes:

[0006] A lightbox is fixedly connected to the PCB and located on the outside of the PCB. The lightbox is provided with several reflective cavities. The several reflective cavities are combined to form an identification part with a time-marking pattern. The four walls of the reflective cavities are all reflective surfaces.

[0007] The light-emitting element is an LED lamp bead with an emission wavelength of 620NM~630NM. Several light-emitting elements are embedded on the PCB and located inside the reflective cavity.

[0008] The lens fits into the mating groove at the front end of the housing;

[0009] A light-transmitting film is fixedly connected to the back of the lens. The light-transmitting film is divided into a light-transmitting part and a light-absorbing part. The light emitted by the light-emitting element is reflected by the reflective surface to the light-transmitting film, then shines through the light-transmitting part onto the lens, and shines out from the front of the housing through the lens to display the time mark pattern of the marking part.

[0010] The light sensor has its connection end fixedly connected to the PCB, and its working end is located in the outer shell space outside the light-transmitting film. It senses the environment outside the shell through its working end to control the operation of the light-emitting element.

[0011] As a further embodiment of this utility model, the angle formed between the reflective surface and the straight line perpendicular to the PCB is ∠1, and the angle is 0°≤∠1≤90°. The reflection angle formed by the light emitted by the light-emitting element on the reflective surface is ∠2, and the angle is 0°<∠2≤45°.

[0012] As a further embodiment of this utility model, the positions of the marking part and the light-transmitting part are corresponding inside and outside, and the projection shapes formed by the two on the plane parallel to the front of the outer shell are the same. The light-absorbing part is the black part in the light-transmitting film, and the color of the light-transmitting part is lighter than the color of the light-absorbing part.

[0013] As a further embodiment of this utility model, the reflective cavities in the marking part are arranged in a matrix distribution or in a straight line along the longitudinal direction of the end face of the light box.

[0014] As a further embodiment of this utility model, the color depth of the light-transmitting part is shallower than the color depth of the lens, and the color depth of the light-absorbing part is higher than the color depth of the lens.

[0015] As a further embodiment of this utility model, the light box is made of ABS, granulated material and acrylic, or a mixture of at least two of the three.

[0016] As a further embodiment of this utility model, the outer side of the light box is fitted with an end cap that surrounds the light box. The light box is fixed in the space outside the PCB by the end cap. The left and right sides of the end cap are provided with first mating holes. The inner walls of the left and right sides of the outer shell are provided with connecting posts. The middle of the connecting posts is provided with second mating holes. The end cap is fixedly connected to the outer shell by inserting connecting parts into the first and second mating holes. The working end of the light sensor passes through the light-transmitting film and extends into one end of the lens.

[0017] As a further embodiment of this utility model, the upper edge of the light box and the upper part of the end cover near the inner edge of the light box are provided with grooves, and the two grooves are joined together to form a third mating hole for cooperating with the light sensor.

[0018] The beneficial effects of this invention are as follows: The clock uses an energy-saving and eye-protecting LED light source, and the light box has a good light reflection effect.

This gives the clock a long battery life, good light display effect and high clarity. Furthermore, the brightness level of the light-emitting element is automatically adjusted by the light sensor to realize intelligent brightness control, making the clock more energy-efficient and simple in structure.

Detailed Implementation

[0028] The embodiments of this utility model will be described below with reference to the accompanying drawings and related examples:

[0029] This utility model relates to an energy-saving LED clock, such as... Figures 1-3 As shown, the system includes a housing 1 and a PCB 2. The PCB 2 is fixedly connected inside the housing 1 and electrically connected to several control buttons on one side wall of the housing 1. The system also includes:

[0030] The light box 3 is fixedly connected to the PCB2 and located on the outside of the PCB2. The light box 3 is provided with a plurality of reflective cavities 4. The plurality of reflective cavities 4 are combined to form an identification part 5 with a time mark pattern. The four walls of the reflective cavity 4 are all reflective surfaces 6.

[0031] The light-emitting element 7 is an LED lamp bead with an emission wavelength of 620NM~630NM. Several light-emitting elements 7 are embedded on the PCB2 and located inside the reflective cavity 4.

[0032] The lens 8 fits into the mating groove 9 at the front end of the outer casing 1;

[0033] A light-transmitting film 10 is attached to the back of the lens 8. The light-transmitting film 10 is divided into a light-transmitting part 11 and a light-absorbing part 12. The light emitted by the light-emitting element 7 is reflected by the reflective surface 6 to the light-transmitting film 10, and then shines onto the lens 8 through the light-transmitting part 11. It then shines out from the front of the housing 1 through the lens 8 to display the time mark pattern of the marking part 5.

[0034] The light sensor 13 has its connection end fixedly connected to the PCB2, and its working end is located in the space of the outer shell 1 outside the light-transmitting film. It senses the environment outside the outer shell 1 through its working end to control the operation of the light-emitting element 7.

[0035] It should be noted that: after the marking section 5 inside the light box 3 forms a structure with a time-marking pattern through multiple reflective cavities 4, the light emitted by the light-emitting element 7 inside the reflective cavity 4, combined with the reflection of light by the reflective surface 6, creates a light effect on the front of the clock that resembles the shape of the reflective cavity 4. Then, under the overall shape of the marking section 5 and the effect of the light, the time is displayed on the front of the clock. The clock uses ultra-bright red LED beads as the light-emitting element 7, which not only ensures that the light source inside the clock can emit sufficient brightness for displaying the time, but also has the characteristic of low power consumption, which reduces the overall power consumption of the clock when displaying the time. Compared to the light source of traditional electronic clocks, it offers better energy efficiency and is also eye-friendly. Furthermore, after the light-emitting element 7 is emitted from the reflective cavity 4, it passes sequentially through the light-transmitting film 10 and the lens 8. The light-transmitting portion 11 on the light-transmitting film 10 disperses the transmitted light, expanding the range of light projected onto the lens 8, before it is emitted outside the clock through the lens 8, thus displaying the time through the light emitted by the light-emitting element 7. In addition, the light sensor 13 automatically senses light and can automatically adjust the brightness level of the light-emitting element 7 according to the ambient light. For example, it automatically dims when the external environment becomes dark at night, thereby achieving intelligent brightness control and making the clock more energy-efficient.

[0036] It needs to be further explained that, such as Figures 4-7 As shown, the angle formed between the reflective surface 6 and the straight line perpendicular to PCB2 is ∠1, and the angle is 40°≤∠1≤90°. The light emitted by the light-emitting element 7 forms a reflection angle of ∠2 on the reflective surface 6, and the angle is 0°<∠2≤45°.

[0037] The formation of ∠1 and ∠2 allows the light emitted by the light-emitting element 7 to be reflected by the reflective surface 6 and then emitted from the light box 3 in a direction perpendicular to the front end of the light box 3 as much as possible. This concentrates the light onto the projection direction of the marking part 5, allowing more light to enter the light-transmitting part 11. This maintains the brightness of the light entering the light-transmitting part 11, which helps the clock meet the light emission requirements for time display in a low-power manner, thus achieving the effect of energy saving for the clock.

[0038] It needs to be further explained that, such as Figure 1 and Figure 8 As shown, the positions of the marking part 5 and the light-transmitting part 11 are corresponding inside and outside, and the projection shapes formed by the two on the plane parallel to the front of the outer shell 1 are the same. The light-absorbing part 12 is the black part of the light-transmitting film 10, and the color of the light-transmitting part 11 is lighter than the color of the light-absorbing part 12.

[0039] The marking section 5 and the light-transmitting section 11 are positioned correspondingly and have the same shape, which allows the light, which resembles the hour marker pattern, to diffuse after entering the light-transmitting section 11. The light-absorbing section 12 is black, which can absorb the light that shines out of the light-transmitting section 11, avoiding excessive scattered light that could cause glare when the clock displays the time. This also helps to maintain the lighting effect formed by the shape of the hour marker pattern.

[0040] Specifically, such as Figure 1 and Figure 3 As shown, the reflective cavities 4 in the marking section 5 are arranged in a matrix distribution or in a straight line along the longitudinal direction of the end face of the light box 3.

[0041] The arrangement of the reflective cavity 4 in the marking section 5 allows the clock to control the light-emitting element 7 in different positions of the reflective cavity 4 to emit light according to the specific time, thereby forming different time marking patterns to meet the clock's requirement for displaying any time.

[0042] Specifically, such as Figure 1 and Figure 2 As shown, the color depth of the light-transmitting part 11 is shallower than the color depth of the lens 8, and the color depth of the light-absorbing part 12 is higher than the color depth of the lens 8.

[0043] The lens 8 has a base color that is darker than the light-transmitting part 11 and lighter than the light-absorbing part 12. This not only makes the light emitted when displaying the time softer to further enhance the eye protection effect, but also makes it more consistent with the light-absorbing part 12 in color, thus making the lighting effect when the clock displays the time better. In addition, the lens 8 is made of a material with good light transmission and no light scattering, which can display the time value of the clock with better clarity, so that people can clearly know the specific time when observing the clock from a distance.

[0044] It should be further explained that, as shown in the figure, the light box 3 is made of one of ABS, granulated material and acrylic, or a mixture of at least two of the three.

[0045] The material used in light box 3 is different from that of ordinary conventional products. It is made of ABS environmentally friendly material + granulation + acrylic material mixed in different proportions. The good reflective effect of the material used in light box 3 makes the light box 3 also have a good reflective effect.

[0046] It needs to be further explained that, such as Figure 1 and Figure 3 As shown, the light box 3 is fitted with an end cap 14 that surrounds the light box 3. The light box 3 is fixed in the space outside the PCB2 by the end cap 14 in the mating groove 9. The end cap 14 is provided with first mating holes 15 on both the left and right sides. The inner walls of the left and right sides of the outer shell 1 are provided with connecting posts 16. The middle of the connecting post 16 is provided with a second mating hole 17. The end cap 14 is fixedly connected to the outer shell 1 by inserting connecting parts into the first mating holes 15 and the second mating holes 17.

[0047] The end cap 14 is used to fix the position of the light box 3 to avoid the effect of deformation of the surface of the light box 3 on the light reflection effect when the connecting parts are inserted into the light box 3.

[0048] Specifically, such as Figures 1-3 As shown, the upper edge of the light box 3 and the upper part of the end cover 14 near the inner edge of the light box 3 are provided with grooves 18. The two grooves 18 are joined to form a third mating hole 19 for cooperating with the light sensor 13. The working end of the light sensor 13 passes through the light-transmitting film 10 and extends into one end of the lens 8.

[0049] During the process of fitting the light box 3 into the end cover 14, the two grooves 18 form a third mating hole 19 at a designated position, thereby forming a position for assembling the light sensor 13 on the front of the clock, so as to facilitate the installation of the light sensor 13.

[0050] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
