Abstract: The present application provides a comfortable lightweight bullet-proof and stab-resistant suit and a preparation method thereof. A first aspect of the present application provides a comfortable lightweight bullet-proof and stab-resistant suit, including a sheath and a protection core sheet disposed in the sheath, and the protection core sheet includes a first protection layer, a second protection layer, a third protection layer and a buffer layer which are sequentially stacked together. The bullet-proof and stab-resistant suit provided in the present application has better response protection characteristics in the process of bullet penetration or knife tip stab, and the prepared aramid unidirectional cloth has low areal density, apparent flatness, no bubbles, and excellent softness, so that any bending within 180° can be realized.

Abstract: The present disclosure providing an LED lamp with a heat sink and with a power supply received in a housing, includes the housing, a body, the power supply received in the housing, and a first connecting member arranged between the housing and the body. The body includes the heat sink, and a plurality of first LED plates installed on the heat sink and electrically connected to the power supply; the first connecting member including an upper portion clamped with the housing, and a lower portion fixed with the heat sink. The present disclosure provides the first connecting member to separate the power supply from the heat sink and increase a distance between the power supply and the heat sink to reduce heat transferred from the first LED plates to the power supply; the first connecting member is clamped with the housing, which is convenient for assembling the LED lamp.
