Detailed Description

In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments accompanied with figures are described in detail below. In the description of the present invention, it should be noted that the terms "in", "up", "down", "left", "right", "inside", "outside", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

Examples are given.

As shown in fig. 1 to 4, the present embodiment includes a lamp socket 1, a PCB driving board 2, an LED module 3, a light-transmitting cover 4, and a lamp ring 5. The upper portion of the lamp holder 1 is provided with a driving cavity 11, the PCB driving board 2 is arranged in the driving cavity 11, a waterproof cover 12 is arranged outside the driving cavity 11, and the waterproof cover 12 is fixed at the position of a cavity opening of the driving cavity 11 to enable the interior of the driving cavity 11 to be relatively sealed, so that a waterproof effect is achieved. Be provided with infrared subassembly and bluetooth module in the PCB drive plate 2, can direct long-range wireless control PCB drive plate 2 drive LED down lamps work through infrared and bluetooth, it is more convenient in the operation.

The lower part of the lamp holder 1 is provided with a reflecting cavity 13, the lamp ring 5 is arranged at the cavity opening of the reflecting cavity 13, and the lamp ring 5 and the lamp holder 1 are fixed through screws. The middle part of the lamp ring 5 is provided with a bracket 51 matched with the LED module 3 and the light-transmitting cover 4. LED module 3 and printing opacity cover 4 from top to bottom the joint hold in the palm the groove 51 in, and LED module 3 lower part offsets with printing opacity cover 4 upper surface, and LED module 3 is connected with PCB drive plate 2. In this embodiment, the LED module 3 is circular, and when the LED module 3 is disposed, the light-emitting surface faces the inside of the reflective cavity 13, and the light is reflected by the reflective cavity 13 and then passes through the light-transmitting cover 4 to be emitted. In addition, a waterproof rubber strip 6 is arranged between the light-transmitting cover 4 and the bracket 51, and the waterproof rubber strip 6 can prevent liquid from entering the lamp holder 1 from the lamp ring 5. In this embodiment, the lamp ring 5 is an aluminum lamp ring 5, which can dissipate heat.

The reflecting cavity 13 is internally provided with a plurality of reflecting structures 7, and the reflecting structures 7 can be one or more of hemispherical cavities formed by inwards sinking or hemispheres bulged outwards. Specifically, when the LED module 3 works under the driving of the PCB driving board 2, light rays irradiate the reflective structure 7 disposed in the reflective cavity 13 to realize diffuse reflection, part of the light rays after diffuse reflection penetrate through the light-transmitting cover 4 to be emitted, and part of the light rays which do not penetrate through the light-transmitting cover 4 continue to be reflected until being emitted. The light reflected diffusely has less stimulation to the eyes than the direct light, does not produce glare and the like, and has uncertainty in the irradiation effect.

In this embodiment, lamp stand 1 upper portion is equipped with the spring clamp 8 that is located 11 both sides of drive chamber, and is concrete, receives external force when the inside rotation of external end when spring clamp 8, and spring clamp 8 takes place deformation, and after spring clamp 8 stopped the atress, spring clamp 8 outwards rotated when resumeing deformation to realize the joint to the external world.

The lamp holder 1 is provided with a flat cable 9 connected with the PCB driving board 2, and the flat cable 9 is connected with a power supply to provide the power supply required by the work of the LED down lamp.

When this embodiment uses, only need be equipped with 12 one ends of waterproof cover promptly and send into the installation position, when 8 outer ends atresss of this in-process spring clamp during to the internal rotation, after the LED down lamp got into the installation position completely, 8 no longer atresss of spring clamp, spring clamp 8 resumes pushing away when deformation outwards kick-backs, and the joint is inboard at the installation position, realizes that the joint is fixed.

The utility model discloses diffuse reflection LED down lamp structural design who describes is reasonable, and light jets out after the diffuse reflection, and the light that compares the direct projection is littleer to the amazing of eyes, can not produce the glare.

The above description in this specification is merely illustrative of the present invention. Various modifications, additions and substitutions may be made by those skilled in the art without departing from the scope of the invention as defined in the accompanying claims.
