CHF3169/CHF3169 energy-saving floodlight loading and unloading light

The calculation of battery capacity and endurance time for portable emergency lights needs to be comprehensively evaluated based on battery energy (Wh), lamp power (W), and actual usage losses. The following are specific calculation methods and precautions:



Basic formulas and unit conversion

1. Total battery energy (Wh)=battery capacity (Ah) × voltage (V)

-For example, if the battery has a nominal 10000mAh (10Ah) of 3.7V, the total energy is:

10Ah × 3.7V = 37Wh

-If the battery is directly labeled as Wh (such as 36Wh), it can be directly used for calculation.



2. Theoretical endurance time (hours)=total battery energy (Wh) ÷ lamp power (W)

-Example: Lamp power 10W, total battery energy 36Wh, theoretical range:

36Wh ÷ 10W=3.6 hours






Light source and lighting performance

High brightness LED light source: using imported LED chips (such as Kore and Riya brands), with high light efficiency and good color rendering. Some models have a luminous flux of over 800 lumens and a spotlight illumination distance of up to 50 meters.

Multi level dimming mode: supports multiple modes such as strong light, working light, energy-saving light, flicker, etc. For example, the FW6330 model has a strong light endurance of 8 hours and a working light endurance of up to 24 hours; The light mode of WHHZ7106 can work continuously for 20 hours.

Uniform spot design: using diffusion agents or special transparent materials (such as polycarbonate) to reduce glare, uniform spot, suitable for long-term operation without fatigue.




Battery capacity and endurance

Capacity unit: usually marked in milliampere hours (mAh) or watt hours (Wh), with longer battery life as the value increases.

Range calculation:

Assuming a searchlight power of 10W and a battery capacity of 36Wh (such as 3.7V/10000mAh lithium battery), the theoretical range is:

36Wh ÷ 10W=3.6 hours (may be shortened in actual use due to brightness adjustment, circuit losses, etc.).








Light source type and characteristics

(1) LED light source

-Advantages:

-High energy efficiency: low energy consumption, high brightness (up to tens of thousands of lumens).

-Long lifespan: The theoretical lifespan can reach over 50000 hours, reducing the frequency of replacement.

-Stability: Strong seismic resistance, suitable for harsh environments.

-Color temperature options: Cold white light (above 6000K) has strong penetration, and warm white light (3000-4500K) has good color rendering.

-Disadvantages:

-Severe high temperatures may affect light efficiency (requiring heat dissipation design).

-Some low-end LEDs have light decay issues (gradually decreasing brightness).

Xenon Lamp (HID)

-Advantages:

-Concentrated lighting: suitable for long-distance illumination (such as search and rescue).

-Color temperature close to daylight: excellent color rendering.

-Disadvantages:

-High energy consumption and large heat generation.

-The lifespan is relatively short (about 2000-3000 hours).

-Start delay (requires preheating).

-Applicable scenarios: search and rescue, usage, and other fields that require strong focus.



(3) COB integrated light source

-Characteristics:

-Multiple LED chips integrated, with uniform and soft light, reducing glare.

-Suitable for up close and wide range lighting (such as camping, maintenance).

-Disadvantage: Weak long-range shooting ability.
