Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings of the description.

[0014] like figure 1 and 2 As shown, a LED filament bulb lamp with a reflective layer includes a glass bulb 1, an upper bracket 2, an LED light bar 3, a stem 4, an LED power supply 5, a lamp holder 6, a guide wire 9, and a coating The reflective layer 8 on the bottom of the glass bulb 1, since the glass bulb 1 is made of transparent material, the reflective layer 8 can be on the inner wall or the outer wall of the glass bulb 1 . The light-reflecting layer 8 may be composed of a light-reflecting inner layer and a light-reflecting outer layer, and the refractive index of the light-reflecting inner layer is higher than that of the light-reflecting outer layer. When the reflective layer 8 is located on the inner wall of the glass bulb 1, the reflective inner layer is located between the inner wall of the glass bulb 1 and the reflective outer layer; whe...

Abstract

The invention discloses an LED (Light-Emitting Diode) filament type bulb lamp with a reflecting layer. The LED filament type bulb lamp comprises a glass bulb shell, an upper bracket, an LED lamp bar, a core column, an LED power supply, a lamp cap, a guide wire and the reflecting layer, wherein the reflecting layer is arranged at the bottom of the glass bulb shell; the reflecting layer is 1-200 microns in thickness, and plays a role in reflecting light. By adopting the LED filament type bulb lamp, the problems of non-uniform illumination and weak light intensity at a center point in the conventional all-angle light-emitting bulb are solved, the illumination uniformity is increased, the problems of apertures and light spots are solved, the light loss is small, energy is saved, and environmental protection is facilitated.

Description

technical field [0001] The invention relates to an LED light bulb, in particular to an LED filament type bulb lamp with a reflective layer. Background technique [0002] Due to the long service life, low energy consumption and significant energy saving of LED lamps, LED lamps have been widely used in daily life as light sources, such as LED light bulbs. LED bulbs that emit light at all angles are very popular, but due to the current light angle of a single LED, it is difficult to achieve uniform light at all angles. Therefore, how to improve the uneven illumination, aperture, light spot, and weak light intensity of the center point of the full-angle LED bulb has become a major problem in LED bulb technology. Contents of the invention [0003] The object of the present invention is to provide an LED filament type bulb lamp with a reflective layer for the deficiencies of the prior art. [0004] The object of the present invention is achieved through the following technical...
