Novel LED panel light with modified heat dissipation for clean rooms

Abstract

The invention relates to a novel LED panel light with modified heat dissipation for clean rooms. The novel LED panel light with the modified heat dissipation comprises two LED light bars, a heat-dissipation body and a shell shaped in a flat box. The two LED light bars are parallelly arranged, the heat-dissipation body is used for dissipating heat of the LED light bars, and the shell shaped in the flat box is used for holding the LED light bars and the heat-dissipation body. A light guide panel is arranged between two LED light bars. The heat-dissipation body comprises two first heat-dissipation panels arranged on two sides of the light guide panel, each LED light bar comprises a PCB (printed circuit board) and an LED light bead arranged on the PCB, and the PCBs and the LED light beads which correspond to two LED light bars are sequentially arranged on the first heat-dissipation panels and face to the light guide panel. The novel LED panel light with the modified heat dissipation is characterized in that the heat-dissipation body further comprises a second heat-dissipation panel which is perpendicular to the two first heat-dissipation panels and arranged at the back of the light guide panel and the inner side of a back panel, and heat-dissipation columns are arranged on the second heat-dissipation panel and face to one side of the back panel. By the arrangement of a novel cylindrical heat-dissipation structure on the outer side of the second heat-dissipation panel, directions and angles of the heat dissipation are enlarged, and speed and effect of the heat dissipation are improved. Since the shell is of a sealed structure less prone to accumulation of dust, the novel LED panel light is especially adaptable to using of the clean rooms.

Description

technical field [0001] The invention relates to an LED lamp, in particular to an LED flat panel lamp. Background technique [0002] As a new development trend in the field of lighting, LED lights have the advantages of high efficiency and energy saving, long life, eye protection, health and environmental protection, high luminous efficiency and safety. As a special LED lamp, LED panel lamp inherits the above advantages, and also has the characteristics of thin thickness, uniform and soft light, so it is widely used in hotels, conference rooms, factories, offices, residences, public facilities, schools and hospitals, etc. Where energy-saving and high color rendering index lighting is required. However, like all lamps made of LED lamp beads, LED panel lamps also have certain heat dissipation problems, and unsatisfactory heat dissipation will greatly affect the life of the lamps. Contents of the invention [0003] The invention overcomes the deficiencies of the prior art an...
