Description

Light modulation structure

Technical Field

The utility model relates to a lamps and lanterns especially relate to a structure of adjusting luminance.

Background

In the field of outdoor landscape lighting at present, dimming lamps of LEDs are more and more widely applied, and particularly, the brightness of the lamps can be visually presented by manually rotating or shifting an adjusting mechanism of a manual dimming lamp. To meet the lighting requirements of different environments.

Structured light of adjusting luminance in the market, its damped design adds a silica gel between two rotation pieces, compresses tightly two structures, relies on the deformation of silica gel, reaches the effect that the damping was adjusted luminance. The structure is used for dimming, the adjustment is free of sound rotation, the hand feeling is poor when the device is used, and the adjustment degree is difficult to grasp when the device is adjusted.

Disclosure of Invention

The utility model aims to solve the problem that to the shortcoming among the above-mentioned prior art, put forward improvement scheme or alternative, especially a structure of adjusting luminance for lamps and lanterns adjust luminance.

In order to solve the above problem, the utility model discloses a scheme as follows: a light modulation structure comprises an upper shell, a lower shell and a main control panel, and is characterized in that the main control panel is fixed on the lower shell; the upper shell is provided with a light adjusting knob, the light adjusting knob is fixed on the lower surface of the upper shell through a gland, and the upper shell is provided with a through hole matched with the light adjusting knob; a through hole is formed in the middle of the gland, a knob switching block is arranged below the light adjusting knob, and the knob switching block penetrates through the through hole to be connected with a light adjuster on the main control panel; two sides of the light adjusting knob are provided with hole grooves, springs are arranged in the hole grooves, and positioning marbles are arranged on the springs; and a circle of wave groove is arranged at the periphery of the through hole and corresponds to the positioning marble.

Furthermore, the structure of adjusting luminance, its characterized in that, the light modulator on knob switching block and the main control board passes through a word groove cooperation and connects.

Further, the dimming structure is characterized in that the upper shell and the lower shell are fixedly connected through a buckle.

The technical effects of the utility model are as follows: this design replaces the damping device of current light modulator with location marble and wave groove, and the interval of adjusting the precision accessible wave groove is adjusted. When the light adjusting knob rotates, the positioning marble moves on the wave groove, so that the hand feeling is enhanced, and the adjustment of each step is clear.

Wherein, 1 is the main control board, 2 is the knob of adjusting luminance, 3 is knob changeover block, 4 is the screw, 5 is the gland, 6 is the location marble, 7 is last shell, 8 is the lower shell, 9 is the wave groove, 10 is the through-hole.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example (b): a light modulation structure comprises an upper shell, a lower shell and a main control panel, and is characterized in that the main control panel is fixed on the lower shell; the upper shell is provided with a light adjusting knob, the light adjusting knob is fixed on the lower surface of the upper shell through a gland, and the upper shell is provided with a through hole matched with the light adjusting knob; a through hole is formed in the middle of the gland, a knob adapter block is arranged below the dimming knob and penetrates through the through hole to be connected with a dimmer on the main control panel; two sides of the light adjusting knob are provided with hole grooves, springs are arranged in the hole grooves, and positioning marbles are arranged on the springs; and a circle of wave groove is arranged at the periphery of the through hole and corresponds to the positioning marble.

The assembly steps are as follows:

A. firstly, the main control panel 1 is fixed on the lower shell 8 through screws, and the knob adapter 3 is pressed on the light modulator on the main control panel, and the two are matched through a straight groove.

B. A positioning ball 6, (an elastic member, an internal spring, a ball, which can move up and down by its spring compression property). It is pressed into two corresponding hole grooves of the light adjusting knob 2.

C. And (3) fixing the assembled component in the step B between the gland 5 and the upper shell 7 by using screws 4, wherein the upper shell 7 is designed with a circumferential array of wave grooves.

D. The upper housing 7 and the lower housing 8 are fixedly connected by a snap fastener, and the light adjusting knob 2 is pressed into the knob adapter block and is matched with the square groove.

After the assembly is completed, the dimming button 2 is rotated, and the positioning marble 6 rotates along the circumference of the wave groove on the upper shell. Thereby generating crisp damping sound, and each grid adjustment is clear.

Claims (3)

1. A light modulation structure comprises an upper shell, a lower shell and a main control panel, and is characterized in that the main control panel is fixed on the lower shell; the upper shell is provided with a light adjusting knob, the light adjusting knob is fixed on the lower surface of the upper shell through a gland, and the upper shell is provided with a through hole matched with the light adjusting knob; a through hole is formed in the middle of the gland, a knob adapter block is arranged below the dimming knob and penetrates through the through hole to be connected with a dimmer on the main control panel; two sides of the light adjusting knob are provided with hole grooves, positioning marbles are arranged in the hole grooves, each positioning marble comprises a spring and a ball, and the ball is arranged on the spring; and a circle of wave groove is arranged at the periphery of the through hole and corresponds to the positioning marble.
