Purui Optoelectronics Introduces Micro SM4TM Surface Mount LED Components with Low Lighting Costs

February 21, 2024

Recently, Purui Optoelectronics announced the launch of the new Puri Optoelectronics Micro SM4TM surface mount LED module, which can reduce the lighting cost of commercial buildings and improve lighting effects.
This new product is a multi-chip chip package that significantly reduces the number, cost, complexity and size of components for diffuse and directional lights. Diffuse lamps and directional lamps are common in modern office and retail establishments. . It leverages Puri's advanced design and manufacturing technology to expand the company's portfolio of solid-state lighting solutions.
Micro SM4 is a light source similar to hot steam or hot filaments in fluorescent and incandescent lamps, with the exception of energy consumption, longevity and control. The Micro SM4 source is only 4.2 watts, but emits light equivalent to a 20-40 watt incandescent lamp or a 20-35 watt B10 halogen lamp, and has a lifespan of several thousand hours. The Micro SM4 assembly also produces high flux densities in a small space, allowing designers, architects and luminaire manufacturers to design and decorate interior spaces with greater freedom.
Although the Micro SM4 module is only 4.2 watts, it can emit 330-500 lumens of light. The color temperature includes warm white (2700-3000 Kelvin) and cool white (5600 Kelvin). The Micro SM4 component will provide a minimum color rendering index (CRI) of 80-90 and a third-order MacAdam Ellipse (3SDCM) color selection for warm white products. The new Micro SM4 LED source also incorporates the latest advancements in gallium nitride (GaN) film growth technology, chip design and automated packaging technology.
The Micro SM4's compact size and directional light quality and color effects provide an advantage for MeLiTec's new directional light products. For products that typically use discrete LED lamps, components can be saved with this less space-consuming surface mount package. This 20-40 watt replacement product segment accounts for $1 billion in the $100 billion lighting market.

Instruction Manual

1. Features

Clock display, 10 sets of adjustable timed power control, randomized power control, manual switch and optional DST setup.

2. First time charging

This timer contains a rechargeable battery. It is normal that the new/old model runs out of battery if it wasn`t being charged for a long period of time. In this case, the screen will not turn on.

To charge : simply plug the timer to a power outlet. The charging time should take at least 15 minutes.

If the screen doesn`t light up or displays garbled characters, simply reboot the system by pressing the [RESET" button.

3. Set clock

Hold [CLOCK" button and [WEEK" button to adjust week.

Hold [CLOCK" button and [HOUR" button to adjust hour.

Hold [CLOCK" button and [MINUTE" button to adjust minute.

Hold [CLOCK" button and [TIMER" button to select 12 hour/24 hour display.

Hold [CLOCK" button and [ON/AUTO/OFF" button to enable/disable DST (daylight-saving-time).

4. Set timer

Press [TIMER" button, select and set timer. Setting rotation : 1on, 1off, 2on, 2off, ...... , 10on, 10off.

Press [HOUR" button to set hour for timer.

Press [MIN" button to set minute for timer.

Press [WEEK" button to set weekday for timer. Multiple weekdays can be selected. ex: if selected [MO", the timer will only apply on every Monday; if selected [ MO, WE, FR", the timer will apply on every Monday, Wednesday and Friday.

Press [RES/RCL" button to cancel the selected on or off timer. The screen will show "-- -- : -- --" , the timer is canceled.

Press [RES/RCL" button again to reactivate the timer.

When timers are set, press [CLOCK" to quit timer setting and return to clock.

5. Random function

Press [RANDOM" button to activate random function, press again to cancel function.

System only runs random function when [AUTO" is on.

Random function will automatically start the timer from 2 to 32 minutes after the setting.

ex : if timer 1on was set to 19:30 with the random function on, the timer will activate randomly between 19:33 to 20:03.

if timer 1off was set to 23:00 with the random function on, the timer will activate randomly between 23:02 to 23:32.

To avoid overlapping, make sure to leave a minimum of 31 minutes gap between different sets of timer.

6. Manual control

Displayed features:

ON : socket turns on.

OFF : socket turns off.

AUTO : socket turns on/off automatically via timer.

Manual ON setting

Press [ON/AUTO/OFF" button to switch from [AUTO" to [ON".

This mode allows socket of the device to power up. Power indicator will light up.

Manual OFF setting

Press [ON/AUTO/OFF" button to switch from [AUTO" to [OFF".

This mode turns socket of the device off. Power indicators will turn off.

7. Electrical parameters

Operating voltage : 230VAC

Battery : NiMh 1.2V

Power consumption : < 0.9W

Response time : 1 minute

Power output : 230VAC/16A/3680W

Q&A
