80mm Fairground Point Light Mock-Up: Set Spacing and Branch Load Before Ride Refurbishment
Quick decision
Use the 80mm body as a visible scale, not as the layout pitch. Approve one full-size bay at day and night, then calculate each electrical branch from 5.76W and confirm the ordered protection version in writing.
Published facts and evidence boundary
| Parameter | Published or derived value |
|---|---|
| Model and format | L-D-80WW; 80mm body; 24 SMD2835 LEDs |
| Light output | Single color; white PCB listed |
| Electrical | DC24V; 5.76W per point |
| Calculated point current | 5.76W / 24V = 0.24A theoretical |
| Published protection wording | IP65/IP67 in page data; IP68 in title |
| Control boundary | No model-specific dynamic pixel protocol is confirmed for this single-color version |
Approve spacing from the rider and spectator routes
The 80mm lens can read as a bold dot at distance, but the required centre spacing depends on fascia color, ambient light, curvature and whether the viewer is moving. A catalogue photo cannot establish that rhythm.
Mock up the tightest curve and a straight bay. Review from the queue, ride perimeter and principal photo position; record the widest spacing that still preserves the intended line without dark gaps.
Freeze the single-color version before ordering
The page identifies an 80mm point with 24 SMD2835 LEDs, an Epistar chip entry, white PCB, single-color output, DC24V and model L-D-80WW. Do not turn the separate controller list into a claim that this exact version is an RGB pixel.
The order line should state color, lens appearance, housing, lead length, connector, cable exit and marking. If animation is required, select and document a different confirmed controllable version rather than assuming it here.
Convert 5.76W into maintainable branch loads
At the published rating, one point draws 0.24A theoretically. Fifty points equal 288W and 12A; one hundred equal 576W and 24A before cable loss and engineering margin.
These are comparison loads, not maximum branch lengths. Divide the ride into accessible fused zones, measure the farthest point under full output and keep connectors within their approved current rating.
Do not confuse a lamp branch with a pixel data chain
For this published single-color configuration, the core design problem is switched or dimmed power distribution. Point count, branch routing and service isolation remain important, but UCS, WS or DMX pixel addressing is not established by the model data.
Freeze the actual dimming or switching device, voltage, polarity and connector on a sample branch. A controller name elsewhere on the page is not enough to define signal topology.
Resolve the IP conflict at order level
The page data mentions IP65/IP67 while the page title says IP68. Those labels cannot be combined into one guaranteed construction; obtain the exact test basis and ordered version before approving exposed use.
Inspect cable entries, rear housing, joints and drainage in the complete mounting assembly. The light's stated grade does not automatically protect field connectors or the ride fascia penetration.
Conditional project decision table
| Project condition | Decision and evidence |
|---|---|
| Close-view decorative fascia | Test a tighter centre spacing on the real color and curvature. |
| Distant ride outline | Compare a wider spacing from the normal spectator route. |
| Dry sheltered installation | Confirm the exact ordered housing; avoid paying for an undefined higher IP claim. |
| Rain or wash-down exposure | Require written IP construction, sealed joints and drainage review. |
| Many points on one elevation | Split into fused service zones and test loaded end voltage. |
| Dynamic effects requested | Do not use this single-color record as proof of pixel control; select a confirmed control version. |
LIKELIGHT L-D-80WW as the project sample
This product fits visible single-color dots on fairground fascia, signs or ride outlines where the 80mm scale and DC24V architecture suit the approved mock-up. Its 5.76W point rating supports transparent branch budgeting.
It is not a substitute for an RGB addressable model when the brief requires per-point animation. LIKELIGHT should supply the exact color, protection construction, lead and connector against the signed sample.
Information required before quotation
- ride elevation and total point count
- proposed centre spacing and viewing distances
- single color and brightness or dimming target
- exposure, cleaning method and required IP evidence
- branch layout, cable routes and available DC24V supplies
- lead length, connector, cable exit and mounting hole details
- sample quantity and acceptance schedule
- production quantity, packaging and delivery deadline
These inputs let LIKELIGHT evaluate visible rhythm, branch current, service zoning and the ordered protection construction together instead of pricing an undefined 80mm lamp.
Frequently asked questions
Does 80mm mean the points should be 80mm apart?
No. It is the body scale; centre spacing comes from the visual mock-up and mounting geometry.
How much current does one point use?
Theoretical current is 0.24A from 5.76W / 24V; verify the production sample.
Is this IP68?
The page wording conflicts, so the exact ordered grade and construction need written confirmation.
Can it display RGB animations?
Not from the confirmed single-color facts. Use a separately confirmed controllable model for that requirement.
