Title:
LED LAMP PROVIDED WITH DOUBLE LAYERS OF BULB HOUSINGS
Document Type and Number:
WIPO Patent Application WO/2015/109481
Kind Code:
A1
Abstract:
An LED lamp provided with double layers of bulb housings comprises a lamp body (1). One end of the lamp body (1) is provided with a lamp holder (2), and the other end is provided with the small bulb housing (3) and the large bulb housing (4) covering the outer side of the small bulb housing (3). An electric appliance component is mounted in internal space (11) of the lamp body (1). The bottom surface of the small bulb housing (3) is provided with an LED chip (5), and the bottom surface of the small bulb housing (3) is a certain distance higher than the bottom surface of the large bulb housing (4). The LED lamp provided with double layers of bulb housings allows light rays of the LED chip (5) to be gradually diffused by means of the two layers of bulb housings (3, 4), so that the light-emitting angle of the whole lamp can be increased. In addition, from the aspect of the appearance, the volume of the lamp body (1) is reduced, and the heat dissipation effect is not affected.
