Detailed Description

The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

The embodiment of the application provides a projection lamp 1. Referring to fig. 1 and 2, the projector 1 includes a housing 11, a light source assembly 12, and a light emitting plate 13. One side of the housing 11 is provided open. The light-emitting plate 13 is covered on the opening, and the light-emitting plate 13 is closely attached to the light source assembly 12. The housing 11 and the light-emitting plate 13 define an inner space of the housing 11, and the light source assembly 12 is disposed in the housing 11. The housing 11 may also house a control assembly 1122 or the like for controlling the light emission of the light source assembly 12. At least part of the area of the light-emitting plate 13 is arranged in a light-transmitting manner, so that the light emitted by the light source assembly 12 can be emitted from the light-emitting plate 13 to illuminate the designated area. The light source component 12 is closely attached to the light emitting plate 13, so that heat generated by the light source component 12 when emitting light can be directly conducted to the light emitting plate 13 with high heat conduction efficiency, and the heat can be rapidly dissipated from the light emitting plate 13. The light emitting plate 13 is tightly attached to the light source assembly 12, so that the heat dissipation effect of the projection lamp 1 can be obviously improved, the use effect of the projection lamp 1 is improved, and the service life of the projection lamp 1 is prolonged.

In some embodiments, referring to fig. 2 to 4, a side of the housing 11 facing the light emitting plate 13 includes a heat dissipation area 111 and a receiving area 112, and the light source assembly 12 is disposed on the heat dissipation area 111, wherein one side of the light source assembly 12 is disposed closely to the heat dissipation area 111, and the other side of the light source assembly 12 is disposed closely to the light emitting plate 13. The heat dissipation area 111 is closely attached to one side of the light source assembly 12, so that heat generated by the light source assembly 12 can be directly conducted to the heat dissipation area 111 of the housing 11 with high efficiency, and then emitted from the heat dissipation area 111 of the housing 11 to the outside. The light-emitting plate 13 is closely attached to the other side of the light source assembly 12, so that heat generated by the light source assembly 12 can be directly conducted to the light-emitting plate 13 with high efficiency, and then emitted to the outside from the light-emitting plate 13. The heat conduction efficiency of the heat dissipation area 111 of the housing 11 and the heat conduction efficiency of the light emitting plate 13 are higher than those of air, and the heat generated by the light source assembly 12 can be dissipated from the heat dissipation area 111 and the light emitting plate 13 in different directions, so that the heat dissipation effect of the light source assembly 12 is obviously improved, the light source luminescence stability is increased, and the service life of the light source assembly 12 is prolonged. Further, since the light emitting plate 13 and the heat radiation area 111 are in close contact with the light source module 12, the volume and thickness of the projector 1 can be reduced, and the structure of the projector 1 can be simplified, so that the manufacturing cost of the projector 1 can be optimized.

In some embodiments, the housing 11 is provided with a plurality of heat dissipation fins 1111 on a side of the heat dissipation area 111 facing away from the light emitting plate 13. Heat of the heat dissipation region 111 can be conducted to the heat dissipation fins 1111 and then dissipated from the heat dissipation fins 1111 into the air. Wherein, the arrangement of the plurality of heat radiating fins 1111 can increase the contact area of the housing 11 with air, and the arrangement of the heat radiating fins 1111 can increase the heat radiating area of the housing 11, thereby facilitating rapid heat radiation.

In some embodiments, the heat dissipation area 111 and the light emitting plate 13 are disposed in parallel, and a portion of the heat dissipation area 111 is provided with the light source assembly 12. The light source assembly 12 is also in a plate shape, and the heat dissipation area 111 and the light emitting plate 13 are arranged in parallel, so that the front and the back of the light source assembly 12 can be better abutted against the light emitting plate 13 and the heat dissipation area 111, and the light source assembly 12 can be tightly attached to the light emitting plate 13 and the heat dissipation area 111, so that the contact surface between the light source assembly 12 and the light emitting plate 13 and the heat dissipation area 111 is increased, and heat dissipation is further facilitated.

In some embodiments, the accommodating area 112 is concavely provided with an accommodating groove 1121, and a control component 1122 is disposed in the accommodating groove 1121, and the control component 1122 is electrically connected with the light source component 12. The control assembly 1122 can control the light source assembly 12 to emit light according to a preset or user setting. The accommodating area 112 and the heat dissipation area 111 are different areas, and the control component 1122 is arranged in the accommodating area 112, and the light source component 12 is arranged in the heat dissipation area 111, so that the light source component 12 and the control component 1122 are arranged separately, the influence of the control component 1122 on the arrangement of the light source component 12 between the heat dissipation area 111 and the light emitting plate 13 is reduced as much as possible, and the heat dissipation area 111 and the light emitting plate 13 can be arranged closely to the light source component 12.

In some embodiments, the light-emitting plate 13 covers the heat dissipation area 111 and the accommodating area 112 at the same time, the area of the light-emitting plate 13 corresponding to the light source assembly 12 is light-transmitting, and other areas of the light-emitting plate 13 are light-impermeable. The light-transmitting arrangement of the light-emitting plate 13 in the region corresponding to the light source module 12 allows the light emitted from the light-transmitting region of the light source module 12 to be emitted, while the light-blocking arrangement of the other regions of the light-emitting plate 13 allows the control module 1122, the wiring, and the fixed structure in the housing 11 to be shielded inside the housing 11.

In some embodiments, the opaque region of the light emitting plate 13 is provided with frosted textures or etched grooves, so that the contact area between the opaque region of the light emitting plate 13 and air can be increased, and thus the heat conducted to the light emitting plate 13 by the light source assembly 12 can be dissipated from the opaque region more quickly.

In some embodiments, the area of the light-emitting plate 13 corresponding to the light source assembly 12 is partially transparent, and the area of the light-emitting plate 13 corresponding to the light source assembly 12 may also be provided with frosted textures or etched grooves, so that, on one hand, the contact area between the area of the light-emitting plate 13 partially transparent and the air can be increased, and therefore, the heat conducted onto the light-emitting plate 13 by the light source assembly 12 can be dissipated from the area partially transparent more quickly. On the other hand, the frosted texture and etched grooves also provide a light homogenizing effect on the light exiting the light source assembly 12.

In some embodiments, the projector 1 further comprises a bracket 14, and the bracket 14 is movably connected with the housing 11. The holder 14 can be rotatably or slidably connected to the projector 1. The bracket 14 is used to support the housing 11. The bracket 14 can support the housing 11 on a flat surface or fix the housing 11 on a wall by means of bolts or the like to hang the housing 11. The movable connection between the bracket 14 and the housing 11 can enable the bracket 14 to rotate or move to different positions under the condition of being fixed, so that the light emitting direction of the projection lamp 1 is changed, and the light emitting of the projection lamp 1 can be more conveniently directed to a designated area.

In some embodiments, in conjunction with fig. 5, light source assembly 12 includes a conductive substrate 121 and a light emitting diode 122 connected to conductive substrate 121. The light emitting diode 122 can be electrically conductive as a conductive source on the conductive substrate 121, and the front and the back of the light source assembly 12 can be more flat due to the arrangement of the conductive substrate 121, so that the front and the back of the light source assembly 12 can be conveniently clung to the light emitting plate 13 and the heat dissipation area 111 respectively. The conductive substrate 121 includes a plurality of light source holders 1212 arranged in an array, and electrode pads 1211 arranged at the ends of the light source holders 1212, the electrode pads 1211 connecting the plurality of light source holders 1212 in parallel. The light source holder 1212 is capable of carrying a plurality of leds 122 and electrically connecting the leds 122 to the electrode pads 1211. The electrode plate 1211 can be used as a common electrode of the light source holders 1212, and after the electrode plate 1211 is connected to a power source, the light source holders 1212 can be electrically connected to each other, so as to supply power to the light emitting diodes 122.

The heat dissipation area 111 is closely attached to one side of the light source assembly 12, so that heat generated by the light source assembly 12 can be directly conducted to the heat dissipation area 111 of the housing 11 with high efficiency, and then emitted from the heat dissipation area 111 of the housing 11 to the outside. The light-emitting plate 13 is closely attached to the other side of the light source assembly 12, so that heat generated by the light source assembly 12 can be directly conducted to the light-emitting plate 13 with high efficiency, and then emitted to the outside from the light-emitting plate 13. The heat conduction efficiency of the heat dissipation area 111 of the housing 11 and the heat conduction efficiency of the light emitting plate 13 are higher than those of air, and the heat generated by the light source assembly 12 can be dissipated from the heat dissipation area 111 and the light emitting plate 13 in different directions, so that the heat dissipation effect of the light source assembly 12 is obviously improved, the light source luminescence stability is increased, and the service life of the light source assembly 12 is prolonged.

Further, the light emitting diode 122 is disposed on a side of the conductive substrate 121 facing the light emitting plate 13, the conductive substrate 121 is disposed in close contact with the heat dissipation area 111, and the light emitting diode 122 is disposed in close contact with the light emitting plate 13. The light emitting diode 122 can be electrically conductive as a conductive source on the conductive substrate 121, and the front and the back of the light source assembly 12 can be more flat due to the arrangement of the conductive substrate 121, so that the front and the back of the light source assembly 12 can be conveniently clung to the light emitting plate 13 and the heat dissipation area 111 respectively. Specifically, the light emitting diode 122 can be closely attached to the light emitting plate 13, and the conductive substrate 121 can be closely attached to the heat dissipation area 111, so that the heat dissipation effect of the projector 1 is optimized.

In some embodiments, the side of the conductive substrate 121 facing the light-emitting plate 13 is further provided with a reflective layer. The light emitting layer can reflect the light emitted by the light emitting diode 122 to the direction of the light emitting plate 13, so that the light generated by the light source assembly 12 can be emitted towards the light emitting plate 13 more, and the illumination effect of the projector 1 is increased.
