Technical Field

[0001] The utility model relates to the technical field of lighting, in particular to a lamp for outdoor lighting. Background Art

[0002] At present, many projects only require outdoor lighting fixtures such as floodlights and tunnel lights to meet functional requirements. In other words, there are low or even no requirements for the appearance of such lamps. However, the appearance of the existing lamps accounts for most of the cost of the lamps. Therefore, how to reduce the cost to a large extent on the basis of meeting the functional requirements has become an urgent problem to be solved. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a lamp for outdoor lighting with a simple structure and low cost.

[0004] The technical solution adopted by the utility model to solve the above technical problems is:

[0005] A lamp for outdoor lighting comprises two support arms, which are arranged at intervals on the left and right and are connected by at least one modular outdoor light source module. The outdoor light source module is detachably connected to the support arms.

[0006] The support arm is a profile support bar, and the front end surface of the profile support bar is recessed from top to bottom and is provided with a long strip-shaped front self-tapping positioning groove. The two sides of the outdoor light source module are provided with front and rear through positioning holes corresponding to the front self-tapping positioning groove. The threaded rod of the self-tapping screw passes through the corresponding positioning hole and is screwed and installed in the corresponding front self-tapping positioning groove to realize the detachable connection between the outdoor light source module and the profile support bar. The above detachable connection structure is simple and easy to install. The support arm is formed by profile extrusion, which is convenient for cutting and adjustment according to the number of outdoor light source modules. Through the mutual cooperation of the front self-tapping positioning groove and the self-tapping screw, the installation position of the outdoor light source module can be adjusted as needed.

[0007] The outdoor light source module includes a heat sink, an LED light emitting assembly and a cable. The front end surface of the heat sink is provided with a light source mounting surface. The LED light emitting assembly includes a lamp board and a lens board. The lens board is mounted on the light source mounting surface and forms a closed space with the light source mounting surface. The lamp board is arranged in the closed space. The lamp board includes an aluminum substrate and a plurality of LED lamp beads arranged on the aluminum substrate. The lens board is provided with a plurality of convex lenses, and each position of the LED lamp bead corresponds to a convex lens. The heat sink is provided with a wire outlet hole, and the cable passes through the wire outlet hole to be electrically connected to the aluminum substrate. The structure is simple and meets the functional requirements for outdoor use.

[0008] The positioning holes are arranged on the radiator. The two support arms are connected through the radiator of the outdoor light source module, and the support arms can also bear part of the heat to assist the radiator in dissipating heat.

[0009] The radiator includes a heat sink, the upper end face of the heat sink is the light source mounting surface, the rear end face of the lens plate is provided with a first mounting frame, the first mounting frame is mounted on the light source mounting surface, the inner wall of the first mounting frame, the light source mounting surface and the lower end face of the lens plate form the enclosed space, the light board is arranged in the enclosed space, and the aluminum substrate is fixedly mounted on the light source mounting surface. The heat sink makes the light source mounting surface a flat end face, which is convenient for the flat mounting of the aluminum substrate, and is convenient for heat conduction and heat dissipation. The setting of the first mounting frame makes it possible to form a closed space between the heat sink and the lens plate when the light source mounting surface is a flat end face for mounting the light board.

[0010] The rear end face of the lens plate is provided with a second installation frame that matches the shape of the first installation frame.

The lens plate is tightly mounted on the heat sink by means of the elastic mounting arms and buckles, which is different from the traditional structure fixed by screws, so that the overall installation is uniformly stressed, and the assembly is convenient and quick. At the same time, it avoids the situation that the lens is squeezed by the screw head so that the lens is subjected to high-intensity pressure for a long time, which accelerates the aging and cracking of the lens, resulting in the loosening and waterproof failure of the lens, and effectively prolongs the service life of the lamp.

[0012] The outer side of the support arm is provided with a lamp bracket, and the lamp bracket is provided with an arc-shaped elevation adjustment slot that runs through the left and right sides for adjusting the elevation angle of the lamp. The side of the support arm is provided with a locking screw hole, and the rod of the locking bolt that matches the locking screw hole passes through the elevation adjustment slot and is screwed into the corresponding locking screw hole to realize the connection and installation between the support arm and the lamp bracket.

The lamp bracket is used to support the lamp and adjust the elevation angle, and the structure is simple and easy to operate.

[0013] There are multiple outdoor light source modules, and the multiple outdoor light source modules are arranged at intervals from top to bottom.

[0014] The rear ends of the two support arms are connected through a power supply mounting bracket, and the rear end surface of the profile support bar is recessed from top to bottom and provided with a long strip-shaped rear self-tapping positioning groove. The two sides of the power supply mounting bracket are provided with front-to-back through-mounting holes at positions corresponding to the rear self-tapping positioning grooves, and the threaded rod of the self-tapping screw passes through the corresponding mounting hole and is screwed and installed in the corresponding rear self-tapping positioning groove to realize the detachable connection between the power supply mounting bracket and the profile support bar. The power supply mounting bracket realizes a more stable connection and installation between the two support arms, and at the same time facilitates the stable installation of the driving power supply.

[0015] The power supply mounting bracket is detachably mounted with a driving power supply, and the rear end surface of the power supply mounting bracket is provided with two self-tapping mounting grooves, which are arranged at intervals up and down, and the driving power supply is directly screwed and mounted in the self-tapping mounting grooves by self-tapping screws. The structure is simple and the installation is convenient. The power supply mounting bracket can be formed by extrusion of profiles, and the screwing position of the self-tapping screws is adjustable, so the installation is more flexible.

[0016] Compared with the prior art, the advantages of the present invention are that the entire lamp is composed of only two supporting arms and a modular outdoor light source module. The overall structure is simple and easy to assemble. On the premise of meeting the use requirements, there is no need to spend a lot of money to shape the outer shell of the lamp, which greatly saves manufacturing costs.
