Problems solved by technology

However, the glass substrate does not conduct heat well and is easily broken due to vibration, causing the series connection of LED chips to break and fail.
Therefore, some people replace it with a metal substrate that is not easy to break, but the metal substrate cannot transmit light and will have the defect of shielding light, resulting in low luminous efficiency of the LED filament. Therefore, how to strengthen the toughness of the LED filament substrate while taking into account its thermal conductivity and The luminous efficiency of LED filament has become the goal of the LED lighting industry's joint efforts

Embodiment Construction

[0029] figure 1 Shown is an embodiment of the present invention, an LED filament 1 includes: a transparent support 2, a metal electrode 3 arranged at both ends of the transparent support 2, an LED chip unit 4 unit and a gold wire 5 arranged in the transparent support 2, and a set Silicone gel 6 wrapping the LED chip unit 4 and the gold wire 5 inside the transparent bracket 2 . The transparent bracket 2 is a bottomless frame, and its size is about 40×2.4mm 2 , the thickness is 0.6mm, the material is high-temperature-resistant and light-transmitting material, high-temperature-resistant transparent silica gel or other plastics with the same properties can be selected, and its light refraction index is between the silica gel that wraps the LED chip and the air, because the transparent bracket 2 There is no bottom, so there is no doubt about blocking the light in all directions, and it can emit light in all directions to improve the luminous efficiency of the filament. In additio...

Abstract

The invention provides an LED filament which is applied to an LED bulb lamp. The LED filament comprises a transparent support, metal electrodes which are arranged at the two ends of the transparent support, an LED chip unit and a gold wire which are arranged in the transparent support and silica gel which is arranged in the transparent support and wraps the LED chip unit and the gold wire. The transparent support is a frame which is bottomless and omnidirectionally light-transmitting so that the luminescence efficiency of the LED filament is not reduced.

Description

technical field [0001] The invention relates to the lighting field, in particular to an LED bulb lamp. Background technique [0002] LED has the advantages of environmental protection, energy saving, high efficiency and long life, so it has been widely valued in recent years and has gradually replaced the status of traditional lighting fixtures. However, LED light is directional, unlike traditional lamps that can illuminate a wide-angle range. Therefore, how to design LED lamps that achieve ultra-wide-angle and full-circumference lighting has become the goal of the LED industry's efforts in research and development. [0003] In recent years, an LED filament that can make LED light sources emit light similar to traditional tungsten bulbs and achieve 360° full-angle lighting has attracted increasing attention from the industry. The production of this LED filament is to connect multiple LED chips in series and fix them on a narrow and slender glass substrate, then wrap the who...
