CHZ Lighting - LED Street Light Manufacturer and LED Flood Light Factory Since 2013


Faqs
1
What will happen if LED driver fails?
Driver failure may cause lamp flicker, partial light‑out or total lamp shutdown. That is why we perform full aging test for every driver before shipment. We include driver within our standard product warranty scope.
2
What is constant‑current driver for LED outdoor light?
Constant‑current driver stabilizes output current for LED chips, avoiding chip burnout caused by grid‑voltage fluctuation, which is core component for long‑life outdoor luminaires. [[Link‑Blog‑driver‑analysis]] We adopt brand‑grade constant‑current driver for engineering‑level products.
3
Do tunnel lights support timing or automatic brightness adjustment according to external daylight?
Dimmable tunnel lights can connect with external light‑sensor controller or smart cloud platform to auto‑adjust brightness responding to outside daylight variation. [[Link‑Smart‑solution‑page]] We can list required control accessories in quotation.
4
What installation ways are available for LED tri‑proof light?
Surface ceiling mounting, suspension chain mounting are standard options. Bracket accessories can be customized upon special site installation needs. Share your installation‑structure information.
5
Can tri‑proof lamps be used in mining sites?
Standard tri‑proof lamp is for general industrial site. For explosive‑gas mining zone, you need explosion‑proof certified luminaires instead of regular tri‑proof lights. [[Link‑Triproof‑product]] Clarify whether your site has explosive‑hazard atmosphere.
6
What color temperature is recommended for tunnel lighting?
4000K neutral white is the mainstream choice for highway tunnels, balancing driver visual comfort and lighting efficiency. 5000K can be adopted for short tunnels. Please refer to local tunnel‑lighting standard document.
7
Are your tunnel lights suitable for highway road tunnel projects?
Yes, our dedicated tunnel‑light series with asymmetric lens can meet highway tunnel lighting standards, and we can provide DIALux simulation for tunnel‑lighting verification. Send your tunnel cross‑section drawing for lighting calculation.
8
How to handle tunnel lighting transition‑zone brightness requirement?
Tunnel projects need multi‑grade brightness groups for access zone, transition zone, interior zone and exit zone. We configure different‑power lamps plus dimming system to realize brightness gradient. [[Link‑Photometric‑service]] Share tunnel length & traffic volume for full lighting proposal.
9
What is the difference between tunnel light and ordinary flood light?
Tunnel lights adopt special asymmetric beam optics, solving tunnel entrance‑exit “black‑hole & white‑hole” visual effect. General flood light cannot meet tunnel‑lighting optical requirement. [[Link‑Blog‑tunnel‑lighting‑tips]] Do not replace tunnel lamp with ordinary flood light for highway tunnel project.
10
Can tri‑proof lights support dimming function?
Selected tri‑proof models support 0‑10V dimming driver. Non‑dimmable version is more cost‑effective for ordinary warehouse lighting projects. Tell us whether brightness adjustment function is required.
11
What IP rating do your tri‑proof light fixtures achieve?
Our tri‑proof series reach IP66 water‑dust proof, anti‑corrosion housing, suitable for heavy‑dust and high‑humidity industrial indoor & semi‑outdoor locations. [[Link‑Triproof‑product]] Avoid using tri‑proof lamps under direct long‑time outdoor sun exposure.
12
Where can tri‑proof LED lights be applied?
Tri‑proof lights are designed for damp, dusty, corrosive‑vapor sites: logistics warehouse, mining auxiliary area, underground parking, factory workshop and livestock facility. [[Link‑Triproof‑product]] Describe your site condition for model selection.
