Abstract: A lighting device includes a light source unit having a substrate and a light emitting diode disposed on the substrate, a heat sink having an inner surface on which the light source unit is disposed and at least one opening, and a top plate being disposed on the heat sink and having a reflective surface which reflects light from the light source unit in a particular direction.

Abstract: A method and system for computer-assisted analyses of best practice safety assessment generates quantitative indicators of safety performance by using a questionnaire with questions in various sections directed to different areas of safety performance evaluation. Scores are given to the questions based on answers entered by an evaluator. The scores for the questions in each section are weighted and summed to provide a section score, and the section scores are weighted and summed to generate an overall score for the assessment. The scores for the individual sections and the overall score can be compared with scores of other clients and the average scores of the industry, and expected losses can be predicted based on the scores.
