Description

However, since the light source and the driving circuit of the existing reading lamp are installed on the same circuit board, the reading lamp cannot ensure that the illumination angle can be flexibly adjusted while ensuring a good light-homogenizing effect. Therefore, there is room for improvement. Utility Model Content

[0033] The following describes the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0034] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.

[0035] In the following description, a large number of details are discussed to provide a more thorough explanation of the embodiments of the present invention. However, it is obvious to those skilled in the art that the embodiments of the present invention can be implemented without these specific details. In other embodiments, well-known structures and devices are shown in the form of block diagrams rather than in detail to avoid making the embodiments of the present invention difficult to understand.

[0036] See also Figures 1 to 8 The utility model provides a reading lamp and a vehicle using the same, which can be used in the field of lighting and display. For example, the reading lamp can be set on the vehicle body to illuminate the space inside the vehicle. The reading lamp provided by the utility model can diffuse the relatively concentrated light in the reading lamp to a wide area, playing the role of diffusion and light uniformity. The reading lamp can ensure that the illumination angle can be flexibly adjusted under the premise of having a good light uniformity effect. The following is a detailed description through specific embodiments.

[0037] See also Figure 1 and Figure 2 In one embodiment of the utility model, a reading light is provided, which may include a rear cover 10, a driving module, a light source module and a lampshade 50, wherein the rear cover 10 and the lampshade 50 are connected to form a shell of the reading light. The rear cover 10 may be used as a mounting body of the reading light, so that the driving module and the light source module are mounted on the rear cover 10.

[0038] Specifically, the driving module is used as the control part of the reading light, and the driving module may include a driving circuit board 20 and a touch film 210. The driving circuit board 20 may be provided with a driving circuit, and the driving circuit may integrate active devices and passive devices to turn on and off the lighting lamp in the light source module, and adjust the brightness of the light source.

[0039] The touch film 210 is a control switch of the driving module, and the touch film 210 can be connected to the driving circuit board 20. The touch film 210 is controlled by touching, for example, the driving circuit board 20 can be controlled by touching the touch film 210, so that the touch film 210 can indirectly control the light source circuit board 30.

[0040] See also Figure 1 and Figure 2 In one embodiment of the present invention, the light source module is used as the lighting part of the reading light. The light source module is detachably mounted on the back cover 10. The light source module may include a lighting lamp, a light source circuit board 30, and a light-homogenizing lens 40. The light source circuit board 30 may be connected to the lighting lamp. The light source circuit board 30 may be electrically connected to the driving circuit board 20 so that the driving circuit board 20 controls the opening and lighting brightness of the lighting lamp. The light-homogenizing lens 40 may be arranged on the irradiation side of the lighting lamp. The irradiation direction of the lighting lamp is the direction of the lighting lamp toward the lampshade 50. The light-homogenizing lens 40 plays a role in homogenizing the light emitted by the lighting lamp.

[0041] Specifically, the light source module can be installed separately, and the light homogenizing lens 40 is arranged on the illumination side of the illuminating lamp, so that the position and angle of the light source circuit board 30 and the light homogenizing lens 40 are easy to adjust, and the deflection angle range of the light of the illuminating lamp corresponding to the light homogenizing lens 40 is increased. In addition, when the driving circuit fails but the illuminating lamp is still in a normal working state, the driving circuit board 20 provided with the driving circuit can be selectively replaced, and the light source circuit board 30 is still retained for continued use, so as to solve the failure problem of the reading lamp and save resources.

[0042] It can be seen that the light source module and the driving module are separately arranged, that is, the lighting part and the control part of the reading lamp are arranged on different circuit boards. Although the spatial volume of the light source module has not been reduced, the light source module can be installed separately, and the light source module can be detachably installed on the back cover 10 for flexible setting, which is convenient for deflecting the angle of the lighting lampshade. The reading lamp can ensure that the lighting angle can be flexibly adjusted under the premise of having a good uniform light effect.

[0043] See also Figure 1 and Figure 2 In one embodiment of the present invention, the light source circuit board 30 and the driving circuit board 20 may be printed circuit boards (PCB). For example, the formation process of the light source circuit board 30 and the driving circuit board 20 may be as follows: after the printed circuit board is designed and manufactured (PCBA, Printed Circuit Board Assembly), various electronic components, integrated circuits, resistors, capacitors, connectors, etc. are installed on the PCB (Printed Circuit Board) through assembly processes such as surface mount technology (SMT, Surface Mount Technology) or through-hole insertion technology (DIP: Dual In-line Package), and are formed through processes such as welding.

[0044] See also Figure 1 and Figure 2 In one embodiment of the present invention, the homogenizing lens 40 is used to adjust the light path of the lighting lamp or change the direction of the light beam. The homogenizing lens 40 uses the principle of reflection or refraction to achieve deflection, for example, using a free-form surface lens, a prism combination or a microlens array. When the lighting lamp is a light-emitting diode (LED), the homogenizing lens 40 can achieve a beam distribution at a specific angle. The homogenizing lens 40 deflects the light beam emitted by the LED light source, and the homogenizing lens 40 converts the light beam with a specific directionality into a nearly uniformly divergent light beam.

[0045] See also Figure 1 and Figure 2 In one embodiment of the utility model, the homogenizing lens 40 diffuses the relatively concentrated light of the illuminating lamp to a wider area, and the homogenizing lens 40 plays the role of diffusing and homogenizing the light of the illuminating lamp. Since the light source module and the driving module block are separately arranged, specifically, the illuminating lamp is installed on the light source circuit board 30, and the driving circuit is arranged on the driving circuit board 20, and the illuminating lamp and the driving circuit are respectively installed on different circuit boards, the reading lamp can ensure that the illumination angle can be flexibly adjusted under the premise of having a good homogenizing effect. In addition, since the light source module is installed separately, the heat dissipation efficiency of the illuminating lamp in the light source module can be improved. The light source circuit board 30 can be an aluminum substrate with good heat dissipation performance.

[0046] See also Figure 1 and Figure 2 In one embodiment of the utility model, different placement grooves can be provided on the back cover 10, and the light source circuit board 30 and the driving circuit board 20 can be arranged in different placement grooves, so that the heat dissipation of the lighting lamp will not affect the normal operation of the driving circuit. The back cover 10 can be provided with a sponge 110, which can play the role of shock absorption, anti-static, and protection for the reading lamp.

[0047] See also Figure 3 and Figure 4 In one embodiment of the utility model, the reading light also includes a flexible connector, and the light source circuit board 30 and the driving circuit board 20 can be electrically connected through the flexible connector, so that the driving circuit on the driving circuit board 20 controls the lighting lamp on the light source circuit board 30.

[0048] Specifically, the flexible connector may be a flexible printed circuit (FPC), and the light source circuit board 30 and the driver circuit board 20 may be electrically connected via the flexible printed circuit, so that the driver circuit on the driver circuit board 20 controls the lighting lamp on the light source circuit board 30. The flexible printed circuit board is made of polyimide or polyester film as a substrate, and has the characteristics of high reliability, flexible printed circuit board, high wiring density, light weight, thin thickness, and good bendability.

[0049] See also Figure 1 and Figure 5 In one embodiment of the present invention, the lampshade 50 may include a light-transmitting portion 510 and a non-light-transmitting portion 520 , wherein the light-transmitting portion 510 corresponds to the light-homogenizing lens 40 , and the non-light-transmitting portion 520 is located around the light-transmitting portion 510 .

[0050] Specifically, Figure 5As shown, when the illuminating lamp on the light source circuit board 30 is in the illuminating state, the light of the illuminating lamp is irradiated to the homogenizing lens 40, and the homogenizing lens 40 diffuses and homogenizes the light of the illuminating lamp. The light irradiated from the homogenizing lens 40 passes through the light-transmitting portion 510 of the lampshade 50 and irradiates to the outside of the lampshade 50, and the non-light-transmitting portion 520 shields the light irradiated from the homogenizing lens 40, so that the light range of the reading lamp can reach the expected design.

[0051] See also Figure 5 In one embodiment of the utility model, the line connecting the light emitting lens 40 and the illuminating lamp on the light source circuit board 30 extends obliquely to the bottom surface of the rear cover 10. The light emitting lens 40 and the light source circuit board 30 are arranged obliquely in the normal direction of the rear cover 10, so that the light emitting lens 40 can deflect the light of the illuminating lamp and even the light of the illuminating lamp.

[0052] See also Figure 6 A clamping structure 70 is provided on the outer side of the homogenizing lens 40, and the clamping structure 70 can be located on the top of the homogenizing lens 40.

[0053] See also Figure 7 The back cover 10 may be provided with a snap-on structure 70, which may be located at the bottom of the back cover 10, and the light source circuit board 30 may be connected to the snap-on structure 70 of the back cover 10. The light source circuit board 30 and the homogenizing lens 40 may be connected to form an integral structure, and then the entirety of the light source circuit board 30 and the homogenizing lens 40 may be assembled to the snap-on structure 70 of the back cover 10, so as to realize the connection between the light source circuit board 30, the homogenizing lens 40 and the back cover 10.

The reading lamp also includes a mask 60, and a snap-fit ​​structure (not shown in the figure) may be provided on one side of the lampshade 50 close to the mask 60, and the mask 60 is connected to the snap-fit ​​structure on the lampshade 50, so as to realize the connection between the mask 60 and the lampshade 50.

[0055] See also Figure 8In one embodiment of the utility model, a vehicle is provided, including a vehicle body 80 and a reading light, wherein the reading light is mounted on the vehicle body 80 to illuminate the space inside the vehicle. The reading light includes a rear cover 10, a driving module, a light source module, a lampshade 50, a mask 60 and a clamping structure 70, and the connection relationship, position relationship and corresponding relationship among the rear cover 10, the driving module, the light source module, the lampshade 50, the mask 60 and the clamping structure 70 are consistent with those described above.

[0056] Specifically, the reading lamp is applied to a vehicle, so that the illumination lamp in the reading lamp has a higher heat dissipation efficiency. For example, the light source circuit board 30 and the driving circuit board 20 are arranged in different placement grooves on the rear cover 10, and the heat dissipation of the illumination lamp will not affect the normal operation of the driving circuit.

[0057] The light source module can be installed separately on the back cover, and the light-homogenizing lens 40 is arranged on the illumination side of the illuminating lamp, so that the position and angle of the light source circuit board 30 and the light-homogenizing lens 40 are easy to adjust, and the light-homogenizing lens 40 increases the corresponding deflection angle range of the light of the illuminating lamp. The reading lamp can ensure that the illumination angle can be flexibly adjusted under the premise of having a good light-homogenizing effect. In addition, when the driving circuit fails but the illuminating lamp is still in normal working condition, the driving circuit board 20 provided with the driving circuit can be selectively replaced, and the light source circuit board 30 is retained for continued use to solve the failure problem of the reading lamp and save resources.
