Product Overview

The Floor-Standing Five-Reflector Shadowless Examination Lamp — 6000LX High Illuminance, 4500K Neutral White Light, Five-Reflector Focused Shadowless, Mobile Floor Stand with Brake Forensic Autopsy & Fine Evidence Examination Professional Illumination System (also referred to as the Floor-Standing Five-Reflector Shadowless Lamp or Forensic Autopsy Shadowless Lamp) is a high-standard professional illumination equipment specifically designed for forensic laboratories, criminal technical departments, and forensic identification institutions. It constitutes a core illumination support equipment in the fields of forensic pathological examination, criminal technical evidence examination, and fine observation in forensic identification. This product adopts a classic five-reflector optical layout. By synergistically projecting light from five different directions and converging it at the center of the work area, it effectively eliminates the various interfering shadows cast by the operator's head, hands, and instruments within the field of view, providing a high-quality, shadowless illumination environment that is uniform, bright, and close to natural daylight, with an illuminance of no less than 6000LX and a color temperature of 4500K. The equipment is integrated onto a mobile floor stand with universal casters and a central brake system. It can be freely moved and stably positioned according to changes in the autopsy table location, examination workstation, or evidence photography area, completely freeing it from the spatial constraints of fixed-installation lighting fixtures. This product is deeply customized for various professional work scenarios, including organ examination and injury assessment during forensic pathological autopsy, auxiliary illumination for high-magnification microscopic observation of tool marks and trace evidence in criminal technical laboratories, and various types of forensic identification projects requiring high-definition observation and documentation in forensic identification institutions. It perfectly adapts to standardized examinations in forensic autopsy rooms, fine comparisons in criminal technical laboratories, evidence reproduction illumination, and teaching demonstrations, among other professional work environments. This fundamentally resolves the operational pain points of ordinary surgical shadowless lamps being fixed in place and immobile, the illuminance and color temperature not being fully suited to the precise interpretation of tissue color and trace morphology required in forensic examinations, and the potential for misjudgment or omission of microscopic features under conventional lighting due to shadow interference. It provides forensic examiners and criminal technical personnel with a "five-direction shadowless focused, high-brightness natural light effect, mobile and ready-to-use" professional-grade visual working environment. It is a key foundational equipment for guaranteeing the accuracy, efficiency, and objectivity of forensic autopsy and evidence examination conclusions.

Technical Principle

This device operates on the optical principle of combining multi-angle cross-projection illumination and diffuse reflection light uniformity. The lamp head assembly consists of five independent lamp units arranged in a circular or quincunx spatial layout. Each lamp unit contains a high-brightness halogen bulb or equivalent LED light source with a rated power of 125W and a rated voltage of AC 24V. The parabolic reflector behind each lamp unit precisely converges the light emitted by the source and directs it towards the center of the work area. The five reflectors project light onto the same target area from different directions with roughly equal luminous flux. When the operator's head, hands, or instruments block the light from one reflector, the light emitted by the other four reflectors from other angles can still reach the target surface unobstructed. This effectively eliminates the umbra and penumbra that are inherently produced by single-direction illumination, achieving an optically "shadowless" illumination effect.

At the light quality control level, the color temperature of the equipment's light source is precisely calibrated to 4500K. This color temperature falls within the neutral white light range, close to the color temperature of natural midday sunlight. It can faithfully reproduce the natural colors of human tissues, organ surfaces, body fluid stains, and various evidence carriers. This avoids visual misjudgments caused by overly warm or cool lighting, such as misinterpreting the degree of tissue congestion, color deviations in bloodstains, or distortion of the background color of document paper. The illuminance of the system at the center of the work surface is no less than 6000LX, far exceeding the light intensity levels of conventional indoor lighting and ordinary desk lamps. This meets the stringent brightness requirements of high-difficulty visual tasks in forensic work, such as the detailed observation of internal structures of dark-colored organ tissues, identification of minute fracture lines, recognition of tissue bridges within wound cavities, and the line-matching comparison of tool marks.

In terms of structural safety and power supply assurance, the bulbs use AC 24V safe low-voltage power supply, which is well below the human body's safety voltage threshold. This fundamentally eliminates the risk of electric shock to the operator caused by bulb breakage or wiring deterioration during autopsy procedures. The total input power of the unit is 150VA, and the power supply adapts to the AC 220V, 50Hz mains standard. The electrical system features overload protection and insulation monitoring functions, fully complying with the safety specifications for medical and laboratory electrical equipment. The stand system adopts a mobile floor-standing design, with the base equipped with universal casters and a central brake system. The operator can push the device with one hand between the examination table, autopsy table, and evidence photography area. Upon arriving at the designated workstation, stepping on the brake securely locks it in place. This combines a high degree of mobility with absolute stability during use, meeting the dual requirements of forensic and criminal technical laboratories for equipment utilization efficiency and site flexibility.

Core Functions and Compliance Operational Value

Five-Reflector Shadowless Focused Optical Design, Providing an Ideal Illumination Environment That Eliminates Visual Blind Spots for Fine Forensic Anatomy and Microscopic Evidence Examination
The device employs a classic shadowless lamp layout using five independent reflectors to synergistically illuminate from different directions. The luminous flux from each reflector converges and superimposes at the center of the target area. Even if the operator leans close to the observation area during the examination and uses both hands to hold instruments for delicate operations, very few obscuring shadows are generated—when any one reflector is blocked, light from the remaining directions continues to fully illuminate the target from other angles. This five-direction shadowless focusing capability provides irreplaceable optical support for detailed operations requiring extremely high stereoscopic visual clarity, such as exploring deep structures within the cranial cavity, observing minute pathological changes in heart valves, tracing the trajectory of wound tracks, comparing tool mark striations, and discerning fingerprint ridge details. It effectively prevents the omission of histopathological features or the misalignment of trace lines due to localized shadows. From the lighting condition level, it ensures the accuracy of forensic examination and evidence identification conclusions, fully meeting the technical requirement stipulated in the Standards for Forensic Pathological Autopsy that examination illumination must be "sufficient, uniform, and free from interfering shadows."

6000LX High Illuminance and 4500K Neutral White Light Effect, Ensuring Accurate Interpretation of Tissue Color and Evidence Morphology
The equipment provides high-brightness illumination with a center illuminance of no less than 6000LX on the work surface, far exceeding conventional laboratory lighting levels. This makes low-contrast evidence features, such as the surfaces of dark-colored organs, minute fracture lines, superficial abrasions, and trace metal debris, clearly distinguishable under sufficient light. The light source color temperature is precisely calibrated to 4500K neutral white light, with a spectral energy distribution close to that of natural midday sunlight. It can faithfully reproduce the original hues of human tissues—including the color change stages of skin bruises, the differences between congestion and ischemia on organ surfaces, the freshness gradient of bloodstains, and the natural colors of various evidence carriers such as documents, fibers, and paint chips—avoiding color misjudgment caused by the color temperature deviation of artificial light sources. This combination of high illuminance and natural light effect allows the forensic examiner to maintain comfortable visual perception during prolonged continuous examinations, with less likelihood of eye fatigue or color afterimages. It provides a standardized and repeatable light environment for injury assessment, histopathological sampling, and evidence photography that require careful discrimination of color and morphology. This meets the normative requirements of forensic identification regarding the color authenticity of images in examination records and the consistency of the operating environment.

Mobile Floor Structure with Brake Lock, Achieving Both Flexible Allocation Among Multiple Workstations and Safe, Stable Operation
The device adopts a mobile floor-stand design, with the base equipped with universal casters and a central brake system. This allows a single unit to be flexibly moved as needed between multiple autopsy workstations in a forensic autopsy room, different examination benches in a criminal technical laboratory, and the evidence photography work area, completely breaking the spatial limitation of fixed ceiling-mounted shadowless lamps being restricted to "one lamp, one position." When needed, it is pushed to the target workstation, and stepping on the brake locks the casters to firmly anchor the device in place, preventing any accidental displacement during autopsy procedures or fine evidence examinations. This mobile deployment capability enables a single unit to serve multiple workstations, significantly improving the utilization efficiency of laboratory equipment and spatial scheduling flexibility. It has extremely high practical value for work modes involving simultaneous multiple autopsies or rotating use of the same examination equipment by multiple personnel. From the equipment level, it effectively supports the efficient operation of forensic and criminal technical laboratories under limited space conditions.

Compliant Application Scenarios

Organ Examination and Injury Assessment Illumination Scenario During Forensic Pathological Autopsy
During systematic forensic pathological autopsies, the forensic examiner uses this equipment as the primary illumination source to conduct a layer-by-layer examination of the organs within the cranial, thoracic, and abdominal cavities. When examining deep and fine structures such as heart valves, the ostia of coronary arteries, and the cerebral arterial circle at the base of the brain, the shadowless focused illumination ensures that the line of sight is not disturbed by shadows cast by the operator's own head or instruments. The high-illuminance neutral white light makes the grey-white foci of myocardial infarction areas, the distribution range of subarachnoid hemorrhages, and the trajectory of minute fracture lines clearly visible. This provides a standardized light environment for the determination of the cause of death, the inference of the injury mechanism, and the professional photography of the autopsy record. The lighting conditions throughout the entire procedure fully comply with the statutory technical requirements of the Standards for Forensic Pathological Autopsy.

Fine Trace Evidence Examination Illumination Scenario for Tool Marks and Trace Evidence in Criminal Technical Laboratories
At the tool mark examination workstation in a criminal technical laboratory, the examiner uses this equipment as an auxiliary light source for a comparison microscope or directly provides illumination for impression models. The five-reflector shadowless design ensures that the examination area remains bright and shadow-free during the frequent process of changing evidence samples, adjusting observation angles, and holding measurement tools. The striation patterns of tool prying marks, the scratch characteristics of lock cylinder pins, and the minute differences in bullet rifling marks are presented in their true morphology under the 4500K natural white light. This provides reliable illumination assurance for the examiner to accurately interpret the degree of striation matching and points of correspondence for features. The examination conditions fully meet the requirements of the technical standards for tool mark identification regarding the observation environment.

Document Examination and Evidence Photography Illumination Scenario in Forensic Identification Institutions
During document examination and evidence photography, the examiner moves this equipment to the evidence photography workstation. Utilizing its shadowless and high-brightness characteristics, it provides uniform illumination for the standardized photographic documentation of documents, bills, developed fingerprint samples, and various types of trace evidence. The five-direction light projection eliminates any shadows that a handheld camera or tripod might cast over the evidence. The 4500K color temperature faithfully reproduces the background color of the paper, the ink color, and the color characteristics of traces developed by fluorescence. This ensures that the color and morphological information in the examination photographs attached to the expert report are completely consistent with the visible features of the physical evidence under standard lighting conditions, providing image evidence that can withstand technical verification during the court's review of the technical appendices to the expert report.

Core Technical Parameters

In terms of optical performance, the center illuminance of the equipment's work surface is no less than 6000LX. The light source color temperature is 4500K neutral white light. Through the five-reflector optical layout, shadowless focused illumination is achieved, effectively eliminating operational shadows. For electrical specifications, the power input is AC 220V, 50Hz. The bulbs use AC 24V safe low-voltage power supply, with a rated power of 125W. The total input power of the unit is 150VA, ensuring safe and reliable operation. For the stand system, a mobile floor-stand design is adopted, with the base equipped with universal casters and a central brake system, allowing for free movement and stable positioning, meeting the need for flexible deployment across multiple workstations. The standard configuration includes one set of the floor-standing five-reflector shadowless lamp main unit (including five reflectors and lampshades) and one mobile floor stand with brake.

Compliant Field Application Cases

In its routine forensic pathological examination work, the forensic identification center of a municipal public security organ deployed this floor-standing five-reflector shadowless lamp in the central autopsy room as the primary illumination equipment. During a complex homicide examination involving multiple sharp-force injuries, the chief forensic pathologist pushed the equipment beside the autopsy table, locked the brake, and adjusted the reflector angle to aim at the wound area on the chest and abdomen of the deceased. Under the five-direction shadowless illumination, the forensic pathologist conducted a systematic observation and measurement of the morphology of the wound angles, the characteristics of the wound margins, and the trajectory of the wound tracks for all stab wounds. The high-illuminance 4500K neutral white light clearly revealed the color and width differences of the abrasion rings around each wound, providing an accurate morphological basis for subsequently inferring the blade width, blade shape, and thrust angle of the piercing instrument. The lighting conditions throughout the entire autopsy process and the examination records were fully documented in the case file through operational photographs. During the court cross-examination, the defense acknowledged the compliance of the examination environment.

During a proficiency testing comparison for tool mark examination, the trace evidence laboratory of a provincial criminal technical science research institute used this equipment to provide auxiliary ambient illumination for the comparison microscope. During the high-intensity work of conducting line-matching comparisons on multiple sets of shear mark samples over several consecutive days, the mobility of the equipment allowed the same lamp to be conveniently deployed between different workstations according to the examination progress. Under the 4500K neutral white light, the line striation morphologies of different samples presented a consistent color background, without visual bias caused by changes in the ambient light source. All examination results successfully passed the blind proficiency test. In their summary, the laboratory concluded that the standardized shadowless illumination environment provided a stable technical assurance condition for the successful completion of this proficiency testing.
