Description

Technical Field

[0001] This utility model relates to the field of LED lighting technology, specifically to a light-focusing device with a built-in reflector cup. Background Technology

[0002] LED lights are lighting fixtures that use light-emitting diodes as the light source. They are semiconductor devices that can convert electrical energy into light energy. When current passes through an LED, electrons and holes recombine in the semiconductor material, releasing energy and emitting it in the form of photons, thus producing light. As a new type of lighting fixture, LED lights have advantages such as energy saving, environmental protection, long lifespan, and high luminous efficiency, and are widely used in home, commercial, industrial, and outdoor lighting.

[0003] A focused LED light with a built-in reflector is a light fixture that combines an LED light source with a reflector. The reflector is specially designed to focus and reflect the light emitted by the LED, thereby achieving a focused light effect. This type of light fixture is usually used in scenarios that require a combination of high brightness and long-distance illumination, such as outdoor lighting. However, existing focused LED lights with built-in reflectors are inconvenient to disassemble and install. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-7 This utility model discloses a focusing lamp device with a built-in reflector cup, including a lamp housing 1. A fixing ring 2 is fixedly connected to the outer wall of the lamp housing 1. Heat sinks 3 are evenly provided along the circumference of the outer wall of the lamp housing 1. One end of the heat sink 3 is connected to the fixing ring 2. The top of the lamp housing 1 is open. A reflector cup 5 is detachably installed in the inner cavity of the lamp housing 1. A perforation 6 is opened in the bottom inner wall of the reflector cup 5. An LED light emitter 7 is installed in the bottom inner wall of the lamp housing 1 through the perforation 6. A lamp cover 8 is detachably connected to the top of the lamp housing 1 to cover its opening.

[0024] Specifically, the fixing ring 2 has through holes 4 between adjacent heat sinks 3.

[0025] In this embodiment, the through hole 4 can reduce the weight of the fixing ring 2 and also facilitate the flow of air through the through hole 4.

[0026] Specifically, positioning grooves 9 are provided on both sides of the reflector cup 5, and a fixing block 10 passing through the positioning groove 9 is fixedly connected to the inner wall of the lamp housing 1.

[0027] In this embodiment, the inner wall of the reflector cup 5 is inclined, and the inner cavity of the reflector cup 5 is larger at the top and smaller at the bottom.

[0028] When the reflector cup 5 is installed inside the cavity of the lamp housing 1, the cooperation between the fixing block 10 and the positioning groove 9 facilitates the positioning and installation of the reflector cup 5.

[0029] Specifically, a movable groove 11 is provided on one side of the fixed block 10, and a first elastic rod 12 is installed on the inner wall of the movable groove 11. The top end of the first elastic rod 12 is connected to a pressure head 13 that presses against the top of the reflector cup 5.

[0030] In this embodiment, when the reflector cup 5 is installed in the inner cavity of the lamp housing 1, the bottom of the reflector cup 5 contacts the bottom inner wall of the lamp housing 1.

[0031] The pressure head 13 of the first elastic rod 12 can press on the top of the reflector cup 5, so that the reflector cup 5 is limited and can maintain a stable state. It can drive the first elastic rod 12 to move away from the end of the reflector cup 5, and can release the pressure head 13 from limiting the reflector cup 5.

[0032] Specifically, the top of the lamp housing 1 is fixedly connected with an arc-shaped piece 14 arranged in a ring, the arc-shaped piece 14 arranged in a ring surrounds the top opening of the lamp housing 1, and the lamp shade 8 is placed on the top of the lamp housing 1 and surrounded by the arc-shaped piece 14 arranged in a ring.

[0033] There is a notch 15 between adjacent arc-shaped pieces 14. A second elastic rod 16 is connected to the top of the lamp housing 1 at the notch 15. The end of the second elastic rod 16 is integrally connected to a pressure block that presses on the lamp cover 8.

[0034] In this embodiment, when the lampshade 8 is placed on top of the lamp housing 1, it is surrounded by the annularly distributed arc-shaped pieces 14. The pressure block at the end of the second elastic rod 16 can press on the lampshade 8, thereby limiting the lampshade 8 and facilitating the removal and installation of the lampshade 8.

[0035] In summary, this built-in reflector-type focusing lamp device allows the lamp cover 8 to be easily removed from the lamp housing 1, and the reflector 5 to be easily removed from the lamp housing 1. When the LED light source 7 is damaged, it is easy to carry out inspection and maintenance. By fixing the fixing ring 2 on the outer wall of the lamp housing 1 and setting the heat sink 3 connected to the fixing ring 2, the heat dissipation of the lamp housing 1 can be facilitated.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
