Embodiment Construction
[0007] The present invention as figure 1 shown
[0008] The alternating current is connected to the LED constant current driver (3) through (1) (2) AC contact points, and after the constant current of the constant current driver passes through, the positive and negative poles on the circuit diagram are connected through wires.
[0009] The heat-conducting substrate (10) (14) is coated with an insulating heat-conducting layer (9) (11) on the front and back, and a circuit diagram (8) (12) is pasted on the insulating heat-conducting layer. Weld the LED light-emitting chip (13) (7) on the corresponding position on the circuit diagram. The heat generated by the LED chip is passed to the base radiator (5) through the heat conduction guide rod (6), and then to the insulating heat conduction plastic shell (4), and (15) is a 360° light halo.

The invention relates to the field of LED bulb lighting, aims to solve the technical problem of the light-emitting angle of an LED chip and provides an LED bulb with 360-degree illumination. The LED bulb with 360-degree illumination is characterized in that LED light-emitting chips are welded on the front and back of a heat conduction substrate; a heat conduction guide rod is mounted in the center of the heat conduction substrate; and the a double-face light-emitting substrate is placed in the center of a lampshade, so that a 360-degree light source is formed.
Description
Technical field: [0001] The invention relates to the lighting field of LED bulb lamps, and aims to solve the problem that the illuminance of LED bulb lamps reaches 360°. Background technique: [0002] LED bulb lamp is a new generation of energy-saving and environmentally friendly light source, and has an irreplaceable market in the field of lighting. Since the light emitted by the LED chip is limited by the light angle, the illuminance can only reach 120°. Invention content: [0003] LED bulb lamps use semiconductor light-emitting technology. Its light-emitting surface is only 120°. When it is used in places that require large-angle lighting, it has the disadvantage of insufficient illumination. It mainly relies on the lampshade to reflect to a large angle, but the reflected luminous flux is uneven. The present invention uses a double-sided circuit, thereby solving the problem that the illuminance can reach 360° from habit to design, and the luminous flux is average. ...
