Background technique

Table lamps are household appliances used for lighting in people's lives, which are convenient for reading, studying, working, etc. The current table lamps on the market basically emit light in the form of side-emitting and direct-emitting. Compared with direct-emitting table lamps, side-emitting table lamps usually use light guide plates to refract light, reducing the stimulation of direct light to the eyes, while avoiding the granularity of direct-emitting lamps and the dark areas caused by too large or too small distance between the lamp beads and the diffuser. However, at the same power and number of lamp beads, the lamp flux of side-emitting table lamps is lower than that of direct-emitting lamps. Therefore, in order to avoid the loss of light flux, side-emitting lamps need to place more lamp beads on both sides of the light guide plate and arrange them evenly, which is difficult to install and has high costs. In addition, the side of the side-emitting table lamp will have inconsistent brightness or even directly see the bright edge.

As shown in Figures 1-6, the utility model provides a double-sided light-emitting lamp holder, comprising:

Two light-emitting units 1, each light-emitting unit 1 includes a light source mounting frame 11 located on one side thereof, an arc-shaped light reflecting plate 12 connected to the light source mounting frame 11 and extending toward the other side of the light-emitting unit 1, and a light-emitting component 13; the light source mounting frame 11 is provided with a mounting bevel 111, the mounting bevel 111 faces the concave side of the arc-shaped light reflecting plate 12, the light-emitting component 13 is arranged on the mounting bevel 111, and the outgoing light emitted by the light-emitting component 13 is reflected and emitted via the arc-shaped light reflecting plate 12; the two light-emitting units 1 are arranged symmetrically with each other, and one side of the light source mounting frame 11 is provided opposite to each other and a dark area structure 24 is provided in the middle to separate the two light-emitting units 1, the dark area structure 24 can reduce the light intensity of the central light superposition area, thereby making the light emitted by the double-sided light-emitting lamp head more uniform and soft.

The double-sided light-emitting lamp holder of the utility model comprises two light-emitting units 1, wherein the light-emitting unit 1 comprises a light source mounting frame 11 located on one side thereof, an arc-shaped reflecting light plate 12 connected to the light source mounting frame 11 and extending toward the other side of the light-emitting unit 1, and a light-emitting component 13. The light source mounting frame 11 is provided with a mounting bevel 111, and the mounting bevel 111 faces the concave side of the arc-shaped reflecting light plate 12. The light-emitting component 13 is arranged on the mounting bevel 111, so that the outgoing light emitted by the light-emitting component 13 is directly irradiated into a reflecting cavity 124 formed on the concave side of the arc-shaped reflecting light plate 12. The arc-shaped reflecting light plate 12 uniformly reflects and emits the outgoing light emitted by the light-emitting component 13, thereby avoiding the loss of luminous flux without increasing the number of light-emitting components 13, reducing costs and facilitating installation. At the same time, the light can be made uniform, soft and anti-glare, and there will be no problem of direct granularity and inconsistent side brightness caused by side lighting. In addition, the two light-emitting units 1 are arranged symmetrically with each other, and one side of the light source mounting frame 11 is opposite to each other and a dark area structure 24 is provided in the middle to separate the two light-emitting units 1. The dark area structure 24 can reduce the light intensity in the central light superposition area, so that the central light comes from the arc-shaped reflective light plates 12 on both sides, thereby avoiding excessive brightness of the light in the central area, and thus making the light emitted by the double-sided light-emitting lamp head more uniform and soft, avoiding irritation to the eyes.

In this embodiment, as shown in FIG2 , the arc-shaped reflective light plate 12 includes one or more arc-shaped reflective parts, and two adjacent arc-shaped reflective parts are mutually clamped together. A clamping groove is provided at one end of the arc-shaped reflective part, and a protrusion adapted to the clamping groove is provided at the other end. The protrusion is provided in the clamping groove of another arc-shaped reflective part so that two adjacent arc-shaped reflective parts are clamped together. The two adjacent arc-shaped reflective parts are connected together by the mutual cooperation of the protrusion and the clamping groove, which is convenient for installation. The arc-shaped reflective light plate 12 with a segmented structure realizes large-span lighting, thereby expanding the lighting area, facilitating the adjustment of the reflection angle, and making the reflected emitted light more uniform. In addition, the segmented structure reduces the difficulty of parts production, and local damage can be replaced locally, thereby reducing production and maintenance costs.

In this embodiment, as shown in FIG. 2 , the arc-shaped light reflecting plate 12 includes three arc-shaped reflecting parts, namely, a first arc-shaped reflecting part 121, a second arc-shaped reflecting part 122, and a third arc-shaped reflecting part 123. The curvatures of the first arc-shaped reflecting part 121, the second arc-shaped reflecting part 122, and the third arc-shaped reflecting part 123 are inconsistent. The protrusion at the other end of the second arc-shaped reflecting part 122 is clamped in the clamping groove at one end of the first arc-shaped reflecting part 121 to be fixed to each other. The protrusion at the other end of the third arc-shaped reflecting part 123 is clamped in the clamping groove at one end of the second arc-shaped reflecting part 122 to be fixed to each other, so that the first arc-shaped reflecting part 121, the second arc-shaped reflecting part 122, and the third arc-shaped reflecting part 123 are connected to each other to form a complete arc-shaped light reflecting plate 12. The above three arc-shaped reflecting parts are only one embodiment of the present application and are not used to limit the present application. In actual situations, the number of arc-shaped reflecting parts can be selected according to the size of the double-sided light-emitting lamp head.

In this embodiment, as shown in FIGS. 1-6 , the double-sided light-emitting lamp head further includes a mounting frame 2, and an inner cavity 21 for accommodating the two light-emitting units 1 is provided in the mounting frame 2. The dark area structure 24 is a connecting column provided in the middle position of the inner cavity 21, and the light source mounting frame 11 is fixed on the connecting column, so that the two light-emitting units 1 are arranged symmetrically on both sides of the connecting column. The connecting column forms a dark area in the middle area, so that the light in the middle area comes from the arc-shaped reflective light plates 12 on both sides, reducing the light intensity in the middle light superposition area, avoiding excessive light in the middle area, and thus making the light emitted by the double-sided light-emitting lamp head more uniform and soft, avoiding irritation to the eyes.

In this embodiment, as shown in FIGS. 1-6 , the mounting frame 2 is an aluminum mounting frame to improve the heat dissipation performance of the double-sided light-emitting lamp holder.

In this embodiment, as shown in Fig. 1-6, the double-sided light emitting lamp head further includes two light emitting units 3 corresponding to the light emitting unit 1, and the light emitting unit 3 includes a diffusion plate 31 and an anti-glare plate 32, and the diffusion plate 31 and the anti-glare plate 32 are sequentially arranged at the lower end of the concave side of the corresponding arc-shaped light reflecting plate 12, and are pressed and fixed by the arc-shaped light reflecting plate 12. During installation, the light emitting component 13 is arranged on the mounting bevel 111 of the light source mounting frame 11, and the mounting bevel 111 faces the concave side of the arc-shaped light reflecting plate 12, so that the light emitting component 13 and the corresponding light emitting unit 3 form an obtuse angle, so that the light emitted by the light emitting component 13 will not directly hit the corresponding light emitting unit 3, but directly hit the reflection cavity 124 formed by the concave side of the corresponding arc-shaped light reflecting plate 12, thereby avoiding the loss of light flux. The light source mounting frame 11 is fixed on the connecting column, and is further pressed and fixed by the arc-shaped light reflecting plates 12 on both sides. The concave side surfaces of the two arc-shaped light reflecting plates 12 are provided with a mirror reflection film, which reflects the outgoing light directly irradiated into the reflection cavity 124 to the light emitting unit 3, and the light emitting unit 3 projects the outgoing light reflected by the arc-shaped light reflecting plate 12 to the desired lighting area. Among them, the diffusion plate 31 is on the top and the anti-glare plate 32 is on the bottom, which are sequentially installed in the inner cavity 21 of the mounting frame 2. The light source mounting frame 11 is fixed on the connecting column to limit the arc-shaped light reflecting plate 12 in the inner cavity 21 of the mounting frame 2, and the diffusion plate 31 and the anti-glare plate 32 are pressed and fixed. The outgoing light is refracted and diffused by the diffusion plate 31 and the anti-glare plate 32, so that the final emitted light is uniform, soft, and has less glare.

It is worth noting that the existing side-emitting lamp head uses the light guide plate to refract the light to reduce the stimulation of direct light to the eyes, while avoiding the granular feeling of direct light and the dark area caused by too large or too small distance between the lamp beads and the diffuser. However, in order to avoid the loss of light flux, this method of using the light guide plate to refract the light usually requires placing more lamp beads on both sides of the light guide plate and arranging them evenly, which is difficult to install and has high manufacturing costs. There is also the problem of inconsistent brightness on the side.

However, under the same power and external test conditions (such as ambient illumination, temperature, lighting height, etc.), the present application can ensure uniform and soft light, and can make the luminous flux close to the level of direct light without increasing the number of light-emitting components 13, and can also avoid the granularity, eye irritation and dark areas of direct light, and there is no problem of evenly arranging the light-emitting components 13 in a side-emitting manner to avoid the problem of inconsistent brightness on the side. In addition, when the span of the light-emitting surface formed by the light-emitting unit 3 of the arc-shaped reflective light plate 12 of the segmented structure is large, a certain angle adjustment can be achieved, thereby expanding the lighting area and making the reflected light more uniform; in addition, the segmented structure reduces the difficulty of parts production, and local damage can be replaced locally, reducing production and maintenance costs.

In this embodiment, as shown in FIGS. 1-5 , the light-emitting component 13 includes an LED light-emitting lamp bead and a ceramic heat sink for fixing the LED light-emitting lamp bead, and the ceramic heat sink is disposed on the mounting bevel 111. The ceramic heat sink is coated with heat-dissipating silica gel for fixing the LED light-emitting lamp bead, and the ceramic heat sink is fixed to the mounting bevel 111 by screws, thereby improving the heat dissipation performance and heat resistance of the light-emitting component 13, making the light-emitting component 13 less likely to deform under high-power operation, ensuring uniformity and stability of the emitted light, and the light-emitting component 13 is wear-resistant and has a long service life.

In this embodiment, as shown in FIGS. 1-6 , a cover plate 22 is provided on the mounting frame 2, and a frosted plate 23 is provided between the cover plate 22 and the arc-shaped light reflecting plate 12. The cover plate 22 is fixed to the mounting frame 2 by screws, which can prevent dust from covering the double-sided light-emitting lamp holder, improve the luminous efficiency of the double-sided light-emitting lamp holder, thereby reducing energy consumption and improving the sealing performance of the double-sided light-emitting lamp holder. Since light is also emitted from the upper part of the double-sided light-emitting lamp holder, the frosted plate 23 is provided between the cover plate 22 and the arc-shaped light reflecting plate 12 to make the light uniform and soft.

In this embodiment, a PCB control board is arranged on the connecting column of the mounting frame 2, and the LED light-emitting lamp beads are connected to the PCB control board by wires. The PCB control board can control the LED light-emitting lamp beads and realize radar control, output voltage control and protection circuit.

At the same time, the effect of making the light uniform, soft, and anti-glare can be achieved, and there will be no granularity of direct-emitting desk lamps and the problem of inconsistent side brightness caused by side-emitting desk lamps; a dark area structure 24 is arranged between the two symmetrically arranged light-emitting units 1, which can reduce the light intensity of the superimposed area of the middle light, so that the middle light comes from the arc-shaped reflecting light plates 12 on both sides, avoiding the light in the middle area from being too bright, thereby making the light emitted by the double-sided emitting desk lamp more uniform and soft, avoiding irritation to the eyes. In addition, the double-sided light-emitting lamp head is connected to the lamp pole arm 5 via a rotating connector 6, so that the double-sided light-emitting lamp head can be rotated at any angle, thereby projecting light to any area that requires lighting, which is convenient and flexible to use.

In this embodiment, as shown in FIG. 7 , the rotating connector 6 is provided with screws, and the screws sequentially pass through the cover plate 22 and the frosted plate 23 to be fixedly connected to the light-emitting unit 1 .

In this embodiment, as shown in FIGS. 7-10 , an adjustment panel 41 is provided on the lamp pole 4 for adjusting the working mode of the double-sided light-emitting desk lamp.

The tomato timer mode button is used to scientifically plan the study, work and rest time. When the double-sided light-emitting desk lamp is used to study or work for a certain period of time (such as 45 minutes), the double-sided light-emitting desk lamp is extinguished and enters the rest mode to avoid eye fatigue. After a period of rest (such as 10 minutes), it enters the next tomato study time.
