Abstract

The invention provides a lamp. The lamp takes an LED filament as a light source; the LED filament comprises a plurality of LED chips, a first support and a second support; the LED chips are connected and fixed to the first support and / or the second support; the first support and the second support are made of metal; and the two ends of the LED chips are electrically connected to the first support and the second support respectively, or the multiple LED chips are divided into a plurality of groups of LED chips which are connected in series, wherein the two ends of each group of LED chips which are connected in series are electrically connected to the first support and the second support respectively.

Description

technical field [0001] The invention relates to the field of lamps, in particular to a lamp. Background technique [0002] Since the emergence of the revolutionary new light source LED in the 20th century, it has quickly become popular in the lighting market due to its advantages of energy saving, environmental protection and long life. LED has become the mainstream lighting source in the future and is widely used in commercial lighting, industrial lighting, outdoor lighting, etc. However, the development of civilian lighting is relatively slow. For many people, LED lights are a new type of light source that has never been heard of. In 2008, Japan’s Ushio Light Source launched a bulb-type lamp “LED Filament Bulb” that uses an incandescent lamp prototype to configure LEDs. LED lamps will be able to understand that it is a familiar lighting lamp. Subsequently, candle lamps, crystal lamps, and bulb lamps using LED filaments as light sources began to appear in large numbers an...
