Embodiment 1

[0030] Such as figure 1 and figure 2 Shown is a schematic diagram related to an embodiment of the present invention.

[0031] A reflective omnidirectional light distribution LED bulb lamp, which includes a cylindrical revolving reflector 10, the revolving reflector 10 has an axially transparent perforation 12, and has a revolving reflector 10 outside the revolving reflector 10 Reflective surface11.

[0032] At both ends of the revolving reflector 10, there are radiators respectively, namely the top radiator 20 and the lamp base radiator 30. The heat can be quickly transferred to the top heat sink 10 and the lamp base heat sink 30 through heat conduction.

[0033] On the heat sink 30 of the lamp holder, combine figure 2 It can be seen that the LED light source 50 is fixed on a light source installation surface 31 of the lamp base heat sink 30, and it can be seen that the LED light source 50 is uniformly distributed around the circumference of one end of the revolving refl...

Embodiment 2

[0041] Such as Figure 5 As shown, the cross-sectional view of the second embodiment of the present invention.

[0042] In this embodiment, the LED light sources 50 are placed on the same plane. Therefore, its processing cost is optimized, and all planar thermally conductive substrates can be directly processed and used, without the need for extra costly items such as special-shaped molds. At the same time, in this embodiment, the revolving reflector 10 is different from the first embodiment in that it is not a straight cylinder, but a revolving body with a variable diameter, so that the revolving reflector 11 can achieve better secondary optical treatment of the LED light source 50 , so that the effect of omnidirectional light is improved.

[0043] It can be seen from Embodiment 1 and Embodiment 2 that the bulb 60 can be set as a highly diffusible material that scatters the light from the LED light source 50, such as a diffuser plate with diffuser particles, which can optim...

Abstract

The invention discloses a reflecting all-around light distribution LED (light-emitting diode) bulb lamp, which is characterized by comprising a rotary reflector, radiating pieces, an LED light source and a driving circuit, wherein the rotary reflector is provided with an axially penetrating perforation and a rotary reflecting surface on the outer side; the radiating pieces are positioned at two ends of the rotary reflector and are in heat conduction connection with the rotary reflector; the LED light source is distributed circumferentially around one end of the rotary reflector and is rotationally arranged on the same radiating piece, and a symmetry axis of the LED light source is a symmetry axis of the rotary reflector; a bulb shell shields the rotary reflecting surface and the LED light source; the driving circuit is connected with the LED light source, controls the LED light source and is arranged in the perforation of the rotary reflector; and the radiating piece has a radiating surface and wholly has a heat conduction loop with the rotary reflector. According to the scheme, the enlargement of the size of the bulb shell and the reflecting surface of the reflector is not limited by a driving containing space, and the radiating capacity of the whole lamp is not weakened, so that the light distribution range of the whole lamp can be widened, and high power output can be guaranteed.

Description

technical field [0001] The invention relates to an LED bulb lamp which utilizes the principle of reflection and has omnidirectional light emitting characteristics. Background technique [0002] LEDs are currently widely used in the field of lighting. In the application of general lighting, the most widely accepted is the replacement of traditional light sources / lamps, especially the LED bulb lamps that replace traditional bulb-shaped light sources, which have been mass-produced. [0003] This type of lighting fixture is used to replace traditional (incandescent) bulb lamps. At present, most LED bulbs have relatively small light emitting angles (generally less than 180 degrees). However, in order to achieve or approach the lighting effect of traditional incandescent lamps, it is necessary to achieve a large-angle range of light distribution (lighting angle greater than 280 degrees). The LED light source is characterized by small size, single-sided light emission, and limit...
