The invention provides a lamp cover assembly for tube element LEDs and a lighting device with the same. The lamp cover assembly comprises a lamp base, a first cover shell and a second cover shell permeable to light; the lamp base is connected with the first cover shell; the first cover shell is connected with the second cover shell in a butt-joint mode to form a sealed space; a heat dissipation part which is made of materials permeable to light and is of a tubular structure is arranged in the sealed space, the peripheral wall face of the heat dissipation part is used for being provided with the tube element LEDs in an attached mode, one end of the heat dissipation part is connected to the first cover shell, and the other end of the heat dissipation part is suspended in the sealed space; in addition, the two portions, located on the inner side and the outer side of the heat dissipation part respectively, of the first cover shell have the height difference, and the two portions are provided with first through holes and second through holes respectively. According to the lamp cover assembly for the tube element LEDs, the heat dissipation problem is effectively solved, and therefore not only can the lighting effect be improved, but also the lighting flux can be increased.
Description
technical field [0001] The invention relates to LED lighting, in particular to a lampshade assembly of a tube-shaped elementary LED and an illuminating device using the lampshade assembly. Background technique [0002] With the global energy shortage and environmental pollution becoming more and more serious, it is imperative to replace incandescent lamps and some energy-saving lamps with high-efficiency, mercury-free integrated compact bulb LEDs. [0003] A mainstream light bulb LED, such as figure 1 As shown, the bulb LED includes a lamp base 11 , a metal heat sink 12 , a plurality of LEDs 13 (medium and high power) and a semicircular lampshade 14 . Among them, the metal heat sink 12 is connected with the lamp holder 11, and a driver is arranged therein; a plurality of LEDs 13 are mounted on the lower surface of the metal heat sink 12, and are electrically connected with the driver; the semicircular lampshade 14 covers the metal heat sink 12 the lower surface. In practi...
