Embodiment 1

[0018] Such as figure 1 As shown, a LED floodlight includes a floodlight body 5, and also includes a hinged rod 4, a rotating bolt 3, a connecting block 2 fixedly connected to the floodlight body 5, and a connecting block 2 fixedly connected The mounting seat 6, the connecting block 2 is provided with a hinged hole and an arc-shaped hole 1 of equal diameter, and the hinged hole is the center of the circle corresponding to the arc section on the arc-shaped hole 1, and the mounting seat 6 is provided with a rotating bolt Holes and hinged through holes, and the hinged rod 4 is located in the hinged hole and the hinged through hole, and the rotating bolt 3 is located in the rotating bolt hole and the arc hole 1.

[0019] Specifically, the set mounting base 6 is fixedly connected to the mounting frame of the LED floodlight, and the fixing between the mounting base 6 and the connecting block 2 mainly depends on the pretightening force of the rotating bolt 3, that is, the irr...

Embodiment 2

[0021] The present embodiment is further limited on the basis of embodiment 1, as figure 1 As shown, in order to simplify the structure of the mounting base 6, so that the mounting base 6 can stably fix the floodlight body 5, the mounting base 6 is composed of a web 61 and two wing plates 62 respectively fixedly connected to the two ends of the web 61 , the connecting block 2 is two pieces, which are respectively fixedly connected to one end of the projection lamp body 5, and the two connecting blocks 2 are arranged symmetrically, and the wing plates 62 are provided with rotating bolt holes and hinged through holes, Each wing plate 62 is fixedly connected with a connecting block 2 through a hinge rod 4 and a rotating bolt 3 respectively.

Embodiment 3

[0023] The present embodiment is further limited on the basis of embodiment 1, as figure 1 As shown, in order to enhance the mutual pressing force between the mounting base 6 and the connecting block 2 during fastening, and further ensure the stability of the angle between the projection lamp body 5 and the mounting base 6, the hinge rod 4 is a connecting bolt.

[0024] In order to increase the frictional force between the connection block 2 and the mounting seat 6 under the pre-tightening force of the bolts, concave-convex fine lines are provided on the junction of the side of the connection block 2 and the arc-shaped hole.

[0025] The projecting lamp body 5 includes a plurality of cooling fins 7, which are arranged in parallel, and the top of the most central cooling fin 7 is the highest, and the height of the cooling fins 7 from the center to both sides The top gradually lowers. The setting of high middle and low ends of the cooling fins 7 helps to prevent the middle part...

Abstract

The invention discloses an LED projection lamp comprising a projection lamp body (5), hinge rods (4), rotary bolts (3), connecting blocks (2) and a mounting seat (6). The connecting blocks (2) are fixedly connected to the projection lamp body (5), and the mounting seat (6) is fixedly connected to the connecting blocks (2). Hinge holes and arc-shaped holes (1) identical in diameter are formed in the connecting blocks respectively. The hinge holes are the circle centers corresponding to arc sections of the arc-shaped holes (1). The rotary-bolt holes and hinge through holes are formed in the mounting seat (6), the hinge rods (4) are positioned in the hinge holes and the hinge through holes, and the rotary bolts (3) are positioned in the rotary-bolt holes and the arc-shaped holes (1). By the LED projection lamp simple in structure, the inclination angle of the mounting seat relative to the connecting blocks is changed conveniently, so that the irradiation area of the projection lamp body can be adjusted conveniently, and highlighting irradiation of the LED projection lamp is facilitated.

Description

technical field [0001] The invention relates to the field of lighting devices, in particular to an LED floodlight. Background technique [0002] After decades of technological improvement, LED light source has become the mainstream product of modern lighting with its advantages of high luminous efficiency, low power consumption, long service life, strong safety and reliability, and environmental protection. Due to the good light-gathering performance and high brightness of LED illuminants, LED light sources are used more and more in the field of key illumination. The illuminants of the existing floodlight body are mostly LED illuminants, and the heat dissipation components are relatively large in size. Huge, this makes the overall volume and heat generation of the floodlight body large. [0003] The existing floodlight body includes a frame and an LED illuminant fixed on the frame, a heat dissipation assembly, an illuminant drive circuit, and a floodlight mount. In the prio...
