In one embodiment, as shown in FIG. 6, the screws 8 are evenly installed in the length direction and / or the width direction of the lens pressing frame 112 ′. In FIG. 6, four screws 8 are installed at equal intervals on the long side of the lens pressing frame 112 ′, and the interval is, for example, 60 mm, and three screws are equally spaced on the short side of the lens pressing frame 112 ′. 8 is installed, and the interval is 56.75 mm, for example.

In another embodiment, as shown in FIG. 7, in the length direction of the lens pressing frame 112 ″, the density of the screws 8 installed from both end portions toward the intermediate portion gradually increases, in other words, from both end portions. The distance between the screws 8 gradually decreases toward the intermediate part. In FIG. 7, the number of the long-side screws 8 is six, the distance between the intermediate parts is 30 mm, and the distance toward both ends changes to 33 mm and 42 mm in this order. To do. In FIG. 7, the density of the screws 8 in the width direction of the lens pressing frame 112 ″ is equal, in other words, the interval between the screws 8 is the same, and the interval is 38 mm. It goes without saying that the screw 8 can be installed so that the density of the screws 8 gradually increases from both end portions toward the intermediate portion in the width direction of the lens pressing frame 112 ″. Preferably, the density of the screws 8 in the length direction of the lens pressing frame 112 ″ is larger than the density of the screws 8 in the width direction.

Needless to say, the specific number and size of the screws 8 are not limited, and the number and density of the screws 8 can be appropriately adjusted according to the size of the entire lens holding frame.

If the screws 8 are installed at even intervals, the waterproof performance of the middle part of the lens holding frame may be slightly inferior. Therefore, by making the distribution in the middle part of the screw more dense, Further, the waterproof effect can be further improved.

There is one isolation wall between the light source chamber 11 and the electric chamber 12, and the light source chamber 11 and the electric chamber 12 are isolated by only one isolation wall, thereby reducing the weight of the lighting fixture, and the lighting fixture.

To the light source chamber 11 and the electrical connection line is preferably a waterproof line. If the LED module 2 and the power source 3 are connected by opening a through hole directly in the isolation wall and drilling a lead wire, the manufacturing cost can be greatly reduced, and the heat transfer can also be reduced.

Preferably, a seal ring can be installed in the through-hole, and the seal ring may be a wedge-shaped silicon ring, and sealing is performed by resin injection based on the seal ring, and high protection of the LED module 2 is achieved. Realize the grade. The flow of the injected resin can be prevented by installing the seal ring, and a better sealing effect can be obtained by combining both.

In one embodiment, the electrical connection lines are equally drawn on the LED module 2 and the power source 3, and the connection parts of both electrical connection lines may be installed in the electrical chamber 12 in order to improve convenience. The free end (connection part) of the electrical connection line in the LED module 2 and the power source 3 is installed as a pluggable terminal compatible with each other, for example, a male terminal and a female terminal are connected to each other, and can be inserted manually. If so, it becomes easier to remove and maintain the components in the electric chamber 12. The pluggable terminal is preferably a waterproof joint, and prevents the LED module 2 or the power source 3 from being affected by water immersion of the terminal.

The front surface of the lamp housing 1 on the side of the light source chamber is a light emitting surface, and preferably a heat radiating fin (not shown in the drawing) is arranged on the back surface. This can be arranged. The front surface on the light source chamber side of the lamp housing 1 is a surface on the outside of the depression angle, and the back surface is a surface on the inside of the depression angle, thereby preventing light output from being blocked by the electric chamber side.

Preferably, a hole row 13 communicating with a position between the light source chamber side and the electric chamber side of the lamp housing 1 or a position close to the top of the depression is provided, and the hole row 13 may be a single elliptical hole.
