Description
Technical field
The present embodiments relate to technical field of LED illumination more particularly to a kind of LED projector lamps.
Background technique
LED projector lamp is carrying out in use, due to having different demands, existing LED light projector to light emitting angle and direction
The frame mode of lamp regulating irradiation angle is all directly to be connected and fixed the bottom case of LED projector lamp by bolt and fixed bracket,
It when regulating irradiation angle, needs first to looser a bolt, after rotating LED Projecting Lamp obtains the angle for wanting to irradiate, tightens spiral shell again
Silk is completed to fix, and LED projector lamp is fixed on identified angle by the frictional resistance between bolt and bottom case.Work as adjusting
After number increases, easily there is bolt and Projecting Lamp contact surface abrasion is excessive, causes frictional resistance insufficient and loosen, moreover, if
When LED projector lamp is heavier, only rely on the frictional resistance between bolt and bottom case be also difficult for LED projector lamp to be effectively fixed in really
Fixed angle.
Summary of the invention
The technical problem to be solved by the embodiment of the invention is that providing a kind of LED projector lamp, adjusting and fixation can be facilitated
Irradiating angle.
In order to solve the above-mentioned technical problem, the embodiment of the present invention provides the following technical solutions first: a kind of LED projector lamp,
Mounting bracket including LED light main body and the connection LED light main body and for being fixed on corresponding fixture, the peace
Dress bracket includes that fixed frame for being fixed on corresponding fixture, one end are fixed in LED light main body and the other end and institute
The adjustable shelf of fixed frame pivot joint is stated, first shaft hole and the second axis hole is offered respectively on the fixed frame and adjustable shelf, separately there is spiral shell
Bolt, which is spirally connected after the first shaft hole and the second axis hole with nut, promotes the fixed frame to abut against with the adjustable shelf, described
Being provided with the side that adjustable shelf abuts against for fixed frame is multiple relative to the first shaft hole radial equally distributed
One division structure, being correspondingly arranged on the side that fixed frame abuts against for the adjustable shelf multiple are in relative to second axis hole
When radial equally distributed second indexing structure, the fixed frame and the adjustable shelf abut against, it is divided into the fixed frame
With on adjustable shelf the first indexing structure and the second indexing structure bumps pairing occlusion.
Further, first indexing structure is indexing raised line, and second indexing structure is indexing trough；Alternatively,
First indexing structure is indexing trough, and second indexing structure is indexing raised line.
Further, the LED light main body includes the bottom case in long strip being made of profile and is assembled in the bottom case
Interior LED light module.
Further, the two lateral walls outer surface of the bottom case is also formed with the necking for running through bottom case along its length
Slot, the opposite sides of the adjustable shelf, which also respectively corresponds to protrude out, is formed with linking arm, and the end of the linking arm forms cross section
Shape and size slide connecting part compatible with the lumenal cross-section shape and size of the necking slot, and the correspondence of the linking arm
Thickness in the position of necking slot notch is less than the width of rebate, and the adjustable shelf is with the slide connecting part of the linking arm end of two sides
It is slidably connected in the necking slot and fits with the inner wall of necking slot.
Further, the inner cavity of the necking slot be circular in cross-section through-hole, the slide connecting part of the linking arm be with
Side is connected to the cylinder of the main part of linking arm.
Further, it is also provided with the first screw hole on the linking arm, separately there is screw to be screwed together in first screw hole simultaneously
Adjustable shelf is fixed on bottom case tight against the correspondence side wall lateral surface in bottom case with inner face.
Further, through-hole is also provided on the linking arm, correspondence offers the second screw hole on the bottom case, separately there is spiral shell
It follows closely through-hole on the adjustable shelf and adjustable shelf is fixed on bottom case in the second screw hole for being screwed together on the bottom case.
Further, the LED light module is the multiple series LED point light source moulds installed along the length direction of bottom case
Group.
Further, the mounting bracket is at least two and is assembled in the pre-position of the bottom case respectively.
Further, elastic washer is also arranged between the tail portion and nut of the bolt.
After adopting the above technical scheme, the embodiment of the present invention at least has the following beneficial effects: that the embodiment of the present invention is installed
Bracket uses the separate structure of fixed frame and adjustable shelf, install convenient, and surround the first axle of fixed frame and adjustable shelf respectively
The first indexing structure and the second indexing structure is arranged in hole and the second axis hole, mutual by the first indexing structure and the second indexing structure
The positioning for being engaged and realizing fixed frame and adjustable shelf is abutted, the contact surface avoided between fixed frame and adjustable shelf uses for a long time
Afterwards due to wearing the phenomenon for causing the irradiating angle of Projecting Lamp that can not fix, the irradiating angle of Projecting Lamp can be effectively fixed.Moreover,
It when needing to adjust LED light main body irradiating angle, need to only looser a bolt, be detached from the first indexing structure and the second indexing structure and sting
It closes, that is, is convenient to LED light main body being adjusted to required irradiating angle, then retorque, make the first indexing structure and the
Two indexing structures are engaged once again, can facilitate adjusting and fixed irradiating angle.
