Embodiment Construction

[0013] As shown in FIG. 4 , it is a schematic diagram of an environment-friendly light bulb of the present invention. The light bulb is composed of a lamp tube 1 , a lamp bead 2 , a lamp pin lead wire 3 and a tungsten coil 4 . There are two lamp pin leads 3, one end of which is folded into a hook, and the two ends of the tungsten coil 4 are buckled on the hooks of the two lamp pin leads 3 respectively, and the lamp bead 2 is wrapped on the lamp pin lead 3 close to the tungsten coil 4 At one end, the lamp bead 2 and the tungsten wire coil 3 are inside the lamp tube 1, the end of the lamp foot lead 3 with the tungsten wire coil 4 is also inside the lamp tube 1, and the other end is outside the lamp tube 1.

[0014] The glass used for the lamp tube 1 and the lamp bead 2 is composed of a high-barium glass tube with a lead content of less than 0.0001%. The barium content in the high-barium glass is higher than 8.4%, and its expansion coefficient is 91 in an environment of 30-380°C. ...

Description

technical field [0001] The invention relates to the lighting field, in particular to an environment-friendly light bulb. Background technique [0002] Since the invention of the light bulb, people have made countless technical improvements to the existing light bulbs in order to pursue a more ideal lighting environment. But the light is getting brighter and brighter, which greatly improves the electro-optical conversion efficiency of the light source. The advent of light-emitting diodes reflects this development trend in the field of lighting, and makes the most comprehensive interpretation of the future prospects of the field of lighting. However, as far as the current application situation and market requirements of household lighting are concerned, the most popular application is the earliest tungsten filament incandescent bulb. Although light-emitting diodes are bound to become the king of lighting in the future due to their superior performance and extremely high elec...
