ANTS LED HIDreplacement bulb for street lamp R&D test report

Timing: LED Light Efficiency Improvement and Long Life

1.LED light source is becoming more and more mature as a substitute light source for traditional HID.
2.HID traditional lamps and lanterns have a huge market stock and strong replacement market demand.

Degree: How to Perfectly Replace HID with LED

1.How can we quickly and cheaply without changing the shape of the original lamps?
Completing the replacement will be a huge market opportunity
2.In the segment replacement market, the current depth of LED excavation is insufficient, lack of systematic research, design professional replacement lamps and lanterns, some customer needs can not meet.

HID Applications – Replaceable Scenarios

HID replacement is very extensive, but what are the disadvantages of current LED replacement?

We analyze the complaints from customers (1):

1.Large size, can not be put in

2.Heavy weight, lamp head droop

We analyze the complaints from customers (2):

3.The new LED lamp does not match the old reflector, and the luminous curve changes.

4.After canceling the rectifier, the LED lamps can not withstand the surge impact of street lamps in batches.

X Product HID Luminescence Verification Analysis（1）

Comparison of HID and current market corn Lamp with same brightness

The left picture shows the original LED corn lamp shining in the lamp shell,
and the right picture shows the old HID lamp shining in the lamp shell.
There are obvious differences, which can not achieve the previous light distribution effect.

X Product HID Luminescence Verification Analysis（1）

Study the size and luminous point of old HID and test the distribution curve in the shell.

X Product HID Luminescence Verification Analysis（3）

We study the market application of HID in specific environment, combine data, analyze and find out the law, and formulate the research direction.
The emphasis is on the shape and size of luminescence.

X Product HID Luminescence Verification Analysis（4）

Quantitative parameter verification:Same luminous position of lamps, but use different product diameter and thickness test.
Conclusion :Diameter has less influence on distribution curve.But if the distribution area of lamp beads at the center point is too large, it will have an impact.

X Product HID Luminescence Verification Analysis（5）

Re-validation: The same diameter and different luminous positions have a great impact on lamps .

Conclusion:
Through hundreds of experiments, the influence of the change of lamp size and luminous position on luminous emission was mastered.
And we have applied for a patent for this research.

X Product Heat dissipation and structure verification analysis

1.Minimum heat dissipation and high light efficiency

According to the optimum scheme with the highest light efficiency and the lowest cost，adopt optimal Current Design Philips 3030

2. Efficient Heat Dissipation Design in Limited Space
Reasonable use of double convective heat dissipation design before and after the lamp board, centralized management of power supply heat, and reasonable use of single and double fans with heat dissipation design according to the use space, to achieve rapid heat dissipation in small space.

Test Design Flowchat

1.Verify the new replacement bulb’s light decay condition with the lighting time
2.Verify the reliability of the new replacement bulb against 6KV surge protection
3.Verify the Reliability of Temperature Induction Devices
4.Verify the anti-electromagnetic drying, conduction and radiation function of the new replacement bulb
5.Verify the consistency of light distribution curve between new replacement bulb and old HID

New replacement bulb’s light decay data with the lighting time:

Summary: The new 80W replacement bulbp has an initial light efficiency of 130 lm/w (+5%) and the light decay is 6% after 5000 hours lighting.

6KV Surge Test Data Recording:

Summary: New corn lamp in input line L-N ,Phase 270degree,the surge impact test with 6KV can pass.

Recording of temperature sensing test parameters of new replacement bulb:

Summary: new replacement bulb temperature rise is less than 40 degrees, which meets the design requirements. When the working environment temperature of corn lamp is more than 60 degrees, it will trigger high temperature protection function.

Anti-EMI, Conduction, Radiation Functional Validation Parameter Recording：

Summary: In AC 220V input test lamp anti-electromagnetic interference (EMC) ability.
Meet EMC performance requirements.

Test curve comparison record:

Summary:

1.New replacement bulb ‘s light decay is 6% after 5000 hours lighting，meets the requirements of LED lighting in the market.
2.The 6KV surge protection device for replacement bulb will not be damaged when it withstands voltage below 6KV.
3.The new replacement bulb built-in temperature sensor can protect the lamp from burning when it is abnormal.
4.The new replacement bulb can be manufactured and sent to the organization for certification. After the certification is qualified, it can be imported into the market for sale.
5.The light distribution curve tends to the luminous curve of the old HID in the lamp housing.
