Description

Outdoor Lighting Fixtures

technical field

The invention relates to an outdoor lighting fixture with good heat dissipation effect and long service life.

Background technique

Outdoor lighting fixtures such as LED street lights generally have high power. During use, the LED light-emitting elements and control elements in the light will generate a lot of heat. It is necessary to dissipate heat from the LED light-emitting elements and control elements to ensure the normal operation of the light. There are two main heat dissipation methods. The first heat dissipation method is to mount the LED light-emitting element on a metal heat dissipation plate with good thermal conductivity, and fix the control element on the metal heat dissipation plate, and then set a heat dissipation device on the lamp housing. During the use of the lamp, the heat generated by the LED light-emitting elements and control elements is transferred to the metal heat sink, and the heat exchange between the metal heat sink and the air makes the heat generated by the LED light-emitting elements and control elements be continuously taken away. To achieve the purpose of heat dissipation, but this heat dissipation method requires the metal heat dissipation plate to have better thermal conductivity and requires a larger surface area of the metal heat dissipation plate, so the cost is higher, and this heat dissipation method only relies on the metal heat dissipation plate and the air. Heat exchange, the heat exchange efficiency is low, which makes the heat dissipation effect poor, and when the sunlight shines on the lamp, it will make the temperature inside the lamp higher, but the heat will be transferred to the LED light-emitting element and the control element through the metal heat dissipation plate. The heat dissipation effect is worse, and the service life of the LED light-emitting element and the control element is shorter; the second heat dissipation method is to install a fan on the lamp, and use the fan to blow the metal heat dissipation plate to accelerate the heat dissipation on the metal heat dissipation plate. This heat dissipation method needs to use a fan, which makes the cost higher, and the installation of the fan is more troublesome, and the fan is easy to burn out at high temperature outdoors, and once the fan burns out, it will not be able to effectively dissipate heat from the LED light-emitting element and the control element.

Contents of the invention

The technical problem to be solved by the present invention is to provide an outdoor lamp that can introduce natural wind into the lamp housing so that the heat dissipation effect is better, can reduce the sunlight exposure of the lamp housing, and has low manufacturing cost and is easy to manufacture. lighting fixtures.

In order to solve the above-mentioned technical problems, the outdoor lighting fixture provided by the present invention includes a lamp housing, and a heat dissipation plate is arranged inside the lamp housing; The wind part has an outer side wall extending obliquely upward from the upper part of the lamp housing to the side of the lamp housing. The outer wall of the air guide part extends upwards obliquely, and the upper or side part of the lamp housing is provided with an air inlet hole, and the outer wall of the air guide part is located above the air inlet hole. When the wall is installed, the outer wall and partition of the air guide part change the direction of the natural wind and then blow it to the cooling plate through the air inlet hole;

In this way, inserting the four partitions in the slot holes can make the partitions more firmly fixed on the support frame, which also makes the partitions more firmly fixed on the lamp housing, so that the air guide component can pass through the partitions. It is relatively stably fixed on the lamp housing, so that the air guide part can withstand a large wind force, avoiding the damage of the air guide part by the attack of strong wind, and the opening area is large, so that a large amount of air can flow into the lamp through the opening Inside the housing, the heat dissipation effect is better.

As an improvement, the slots are provided with four fixing seats symmetrically distributed with respect to the intersection points of the slots, and each fixing seat is provided with a threaded hole. Correspondingly, the four partitions are provided with With respect to the four fractures distributed symmetrically at the intersections of the four partitions, the four fractures are set in one-to-one correspondence with the four fixing seats, and the bottom of the air guiding part is provided with four through holes respectively located on the four fractures. When the four partitions are inserted into the slots, the four fractures are inserted into the four fixing seats one by one, and the four through holes and the four threaded holes are set on the coaxial lines corresponding to each other. A fastening screw is screwed in the through hole and the threaded hole of the line. In this way, the air guiding part is fixed on the supporting frame by four screws, the air guiding part is firmly fixed, and the screws are very convenient to disassemble, so that the disassembling and assembling of the air guiding part is very convenient.

As an improvement, the central positions of the support frames are connected to each other to form a support plate, and the bottom of the wind guiding component is fixed on the support plate. In this way, the support plate can play a role of supporting the air guide component, the support plate has a large area, can bear a relatively large weight, and can prevent the support frame from being deformed due to high pressure.

As an improvement, the projected surface of the outer wall of the air guide component vertically projected on the lamp housing covers the lamp housing in the width direction. In this way, the area of the air guide part is relatively large, and the air guide part can block more sunlight, which can minimize the time for sunlight to irradiate the lamp housing, further reduce the temperature of the lamp housing, and further improve the heat dissipation of the present invention. Effect, further improve the service life of the present invention.
