Frameless Panel Lamp Chassis Mounting for Light Emission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing panel lamps with aluminum frames incur high installation costs and result in poor light-emitting effects and angles due to the light-shielding ring formed at the light-emitting opening.
Innovation Solution
A frameless panel lamp design featuring a chassis with outward-bent side plates and convex rings to securely bond the light-transmitting plate without an aluminum frame, preventing adhesive overflow and ensuring optimal light emission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If an aluminum frame is used to install the light-transmitting plate, then the structural stability is improved, but the installation cost increases and the light-emitting effect deteriorates due to the light-shielding ring
Solution Approach 1:
The patent removes the aluminum frame from the installation structure, extracting the light-shielding element that causes the harmful light-shielding ring effect. The light-transmitting plate is directly installed on the chassis using adhesive, eliminating the frame that previously increased cost and blocked light.
Solution Approach 2:
The patent merges the light-transmitting plate directly with the chassis by eliminating the intermediate aluminum frame structure. The adhesive bonding creates a direct connection between the plate and chassis, reducing component count and eliminating the light-shielding ring while maintaining structural integrity.
2Stability of the object's composition
If an aluminum frame is used to install the light-transmitting plate, then the structural stability is improved, but the light-emitting angle is limited resulting in poor light-emitting effect
Solution Approach 1:
The aluminum frame is removed from the structure, eliminating the light-shielding ring that blocked and limited light emission. This allows light to emit freely from the entire perimeter of the light-transmitting plate, improving both the light-emitting effect and the viewing angle.
Solution Approach 2:
Instead of using a frame to hold the plate (which blocks light), the patent inverts the approach by having the plate directly contact the chassis surface. The mounting portions bend outward to secure the plate from below, allowing light to emit outward without obstruction from a front-facing frame.
3Ease of manufacture
If the light-transmitting plate is bonded directly to the chassis without an aluminum frame, then the installation cost is reduced and light-emitting effect is improved, but the adhesive may overflow onto the light-emitting surface
Solution Approach 1:
The mounting portions are pre-formed with convex rings that create designated adhesive containment areas before the bonding process. These structural features are built into the chassis, guiding adhesive placement and preventing overflow onto the light-transmitting plate's light-emitting surface.
Solution Approach 2:
The convex rings formed by the bent mounting portions act as intermediary structures between the adhesive and the light-transmitting plate. They serve as barriers that contain the adhesive within specific zones, preventing direct contact with the plate's light-emitting surface while still allowing effective bonding.

Function Achieved in This Case
This design reduces installation costs, enhances light-emitting effects by aligning the light-emitting surfaces, and improves the light-emitting angle of the panel lamp.
Implementation Method 1
an adhesive is disposed between the first convex ring and the bending portion, and the light-transmitting plate is bonded to the horizontal portion through the adhesive

AI summary
The present application provides a frameless panel lamp, which includes a chassis (1), a light source assembly (2), a driving assembly (3), and a light-transmitting plate (4); the light source assembly (2) is disposed inside the chassis (1), the chassis (1) includes a base plate (11) and side plates (12) surrounding edges of the base plate (11), and each of the side plates (12) is provided with a mounting portion (13) bending outward away from the edges of the base plate (11); the mounting portion (13) includes a horizontal portion (131) and a bending portion (132) bending toward a light-emitting direction, and the horizontal portion (131) is provided with a first convex ring (1311) toward the light-emitting direction; an adhesive is disposed between the first convex ring (1311) and the bending portion (132), and the light-transmitting plate (4) is bonded to the horizontal portion (131) through the adhesive and is attached to a top portion of the first convex ring (1311). The light-transmitting plate (4) is fixed on the mounting portion (13) through bonding, and the aluminum frame can be omitted at this time, which saves cost and does not affect the light-emitting effect; at the same time, the first convex ring (1311) provided on the horizontal portion (131) can be used to prevent the adhesive from overflowing to the light-emitting surface of the light-transmitting plate (4), ensuring the light-emitting effect of the light transmitting plate, and due that the aluminum frame is omitted, the light-emitting surface of the chassis (1) can coincide with the light-emitting surface of the light-transmitting plate (4), thereby effectively ensuring the light-emitting effect and light-emitting angle of the panel lamp.
