Description

Technical Field

[0001] The utility model relates to the field of lighting lamps, in particular to a car lighting lamp which is convenient for heat dissipation. Background Art

[0002] The elevator is equipped with a car lighting system to illuminate the interior of the elevator. Figure 1 As shown, cavities are formed on the left and right sides of the aluminum profile for installing a built-in control power supply. The light source board and the light-transmitting plate are installed in the middle cavity. Strip fins are also provided on the top for heat dissipation. When installed, it is fixed to the top of the elevator with the mounting screws above.

[0003] The control power supply and light source board both generate heat during operation. This structure only has fins on the top for heat dissipation, and these are blocked by the upper bracket during installation, resulting in poor airflow and poor heat dissipation. Therefore, we designed a car lighting that facilitates heat dissipation. Utility Model Content

[0004] In order to solve the technical problem that fins are set on the top for heat dissipation, but are blocked by the upper bracket during installation, resulting in poor airflow and poor heat dissipation effect, the utility model provides a car lighting lamp that is easy to dissipate heat.

[0005] The utility model is implemented by the following technical solution: a car lighting lamp that is convenient for heat dissipation, comprising an aluminum frame, four sets of mounting screws are provided on the top of the aluminum frame, cover plates are screwed to the front and rear sides of the aluminum frame, inner support plates are symmetrically provided inside the aluminum frame, an installation cavity is formed between the two inner support plates and the aluminum frame, a light source plate is provided above the interior of the installation cavity, a plurality of linearly distributed LED lamp beads are provided on the light source plate, and a light-transmitting plate is provided at the bottom end of the interior of the installation cavity;

[0006] The two inner support plates and the left and right sides of the aluminum frame form two side cavities. The left and right sides of the aluminum frame are provided with a plurality of linearly distributed side holes. The top of the aluminum frame is provided with a plurality of linearly distributed connecting holes. The side holes and the connecting holes are both connected to the inside of the side cavity, and the connecting holes are not connected to the inside of the installation cavity.

[0007] As a further improvement to the above solution, two sets of partition plates are symmetrically arranged in front and back inside each side cavity, and a power cavity is formed between the two partition plates. A built-in control power supply is installed in the power cavity, which separates the power cavity from the side cavity and does not communicate with each other, thereby forming a seal for the built-in control power supply and thus protecting it.

[0008] A second side fin is provided on the outward side of each partition plate for dissipating heat inside the power cavity.

[0009] As a further improvement to the above solution, the side cavity is not connected to the power cavity, and the side hole and the communication hole are not connected to the power cavity, forming a sealed structure so that external moisture and dust will not affect the built-in power supply;

[0010] The left and right sides of the aluminum frame are both provided with openings, which are communicated with the power cavity, and mounting plates are mounted on the openings by screws, which facilitates the installation and removal of the built-in power supply and can form a seal.

[0011] As a further improvement to the above solution, the number and position of the communication holes and the side holes correspond one to one, so that the communication holes and the side holes can form convection, thereby facilitating the circulation of airflow and improving the heat dissipation effect;

[0012] The inner support plate is provided with a plurality of linearly distributed side fins on the outward side to facilitate heat dissipation of the heat generated inside the installation cavity.

[0013] As a further improvement of the above solution, the upper end of the aluminum frame is recessed downward to form a groove, and a plurality of top fins are provided in the groove;

[0014] The cover plate has a notch on its top, which corresponds to the groove. The top of the aluminum frame is connected front to back, which facilitates the circulation of airflow front to back.

[0015] As a further improvement of the above scheme, the bottom ends of the two side cavities are respectively provided with guide strips, the outer ends of the guide strips are lower than the inner ends, and the outer ends of the guide strips are above the bottom ends of the side holes. Water droplets formed when the water vapor formed inside is liquefied will fall onto the guide strips, and then flow to the outside along the sides and side holes, without gathering, and also facilitating the outflow of impurities that fall into the inside.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. The utility model opens side holes on the left and right sides of the aluminum frame and a connecting hole on the top. Both the side holes and the connecting hole are connected to the side cavity of the aluminum frame, so that air can flow in the side cavity and form convection, thereby dissipating heat and improving the heat dissipation effect.

[0018] 2. The power supply cavity with a sealed structure separated by the side cavities on the left and right sides of the aluminum frame is used to install the built-in control power supply and protect the built-in control power supply. The side cavity can dissipate heat and form convection on multiple surfaces of the power supply cavity and the installation cavity, thereby improving the heat dissipation effect.

It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0027] Example:

[0028] Please combine Figure 2-Figure 5 The present embodiment provides a car lighting lamp that facilitates heat dissipation, including an aluminum frame 1, four sets of mounting screws 4 are provided on the top of the aluminum frame 1, cover plates 2 are screwed to the front and rear sides of the aluminum frame 1, inner support plates 12 are symmetrically provided inside the aluminum frame 1, and an installation cavity is formed between the two inner support plates 12 and the aluminum frame 1, a light source board 7 is provided above the interior of the installation cavity, a plurality of linearly distributed LED lamp beads are provided on the light source board 7, and a light-transmitting plate 6 is provided at the bottom end of the interior of the installation cavity;

[0029] Two side cavities 13 are formed between the two inner support plates 12 and the left and right sides of the aluminum frame 1. A plurality of linearly distributed side holes 11 are provided on the left and right sides of the aluminum frame 1. A plurality of linearly distributed connecting holes 16 are provided on the top of the aluminum frame 1. The side holes 11 and the connecting holes 16 are both connected to the inside of the side cavity 13, and the connecting holes 16 are not connected to the inside of the installation cavity.

[0030] Two sets of partition plates 8 are symmetrically arranged in front and back inside each side cavity 13. A power cavity 14 is formed between the two partition plates 8. A built-in control power supply is installed in the power cavity 14. The power cavity 14 is separated from the side cavity 13 and is not connected to each other, so as to form a seal for the built-in control power supply and thus protect it.

[0031] A second side fin 81 is provided on the outward side of each partition plate 8 for dissipating heat inside the power cavity 14 .

[0032] The side cavity 13 is not connected to the power cavity 14, and the side hole 11 and the communication hole 16 are not connected to the power cavity 14, forming a sealed structure so that external moisture and dust will not affect the built-in power supply;

[0033] The left and right sides of the aluminum frame 1 are both provided with openings, which are connected to the power cavity 14, and a mounting plate 3 is mounted on the opening by screws, which facilitates the installation and removal of the built-in power supply and can form a seal.

[0034] The number and position of the connecting holes 16 and the side holes 11 correspond one to one, so that the connecting holes 16 and the side holes 11 can form convection, thereby facilitating the circulation of airflow and improving the heat dissipation effect;

[0035] The inner support plate 12 is provided with a plurality of linearly distributed side fins 15 on the outward side to dissipate the heat generated inside the installation cavity.

[0036] The upper end of the aluminum frame 1 is concave downward to form a groove, and a plurality of top fins 5 are arranged in the groove;

[0037] There is a notch on the top of the cover plate 2, which corresponds to the groove. The top of the aluminum frame 1 is connected front to back, which facilitates the circulation of airflow front to back.

When the water vapor formed inside is liquefied, the water droplets formed will fall onto the guide strips 9, and then flow to the outside along the sides and side holes 11. They will not gather, and it is also convenient for impurities that fall into the inside to flow out.

[0039] The implementation principle of a car lighting lamp that facilitates heat dissipation in the embodiment of the present application is as follows: in actual use, the car lighting lamp is installed above the elevator. Since the ventilation inside the elevator itself causes air flow, the air can flow through the side hole 11 and the connecting hole 16 in the side cavity 13 of the aluminum frame 1, thereby improving the overall heat dissipation effect of the car lighting lamp;

[0040] By setting side holes 11 on the left and right sides of the aluminum frame 1, and a communication hole 16 on the top of the aluminum frame 1, the side holes 11 and the communication hole 16 are communicated with the side cavities 13 of the aluminum frame 1, so that the airflow can flow in the side cavities 13 and form a convection, thereby achieving heat dissipation, and improving the heat dissipation effect.

[0041] The power supply cavities 14 in the side cavities 13 on the left and right sides of the aluminum frame 1 are sealed at the partition, and are used for installing the built-in control power supply, so as to protect the built-in control power supply, and the side cavities 13 can dissipate heat and form a convection for the power supply cavities 14 and the installation cavities, thereby improving the heat dissipation effect.

[0042] The above-mentioned embodiments are only preferred embodiments of the present application, and cannot be used to limit the scope of protection of the present application. Any non-substantial changes and replacements made by those skilled in the art on the basis of the present application shall belong to the scope of protection of the present application.
