Description

LED screw light

technical field

The utility model relates to the lighting field, in particular to an LED screw lamp.

Background technique

The traditional screw lamp was originally an incandescent bulb, which had low illuminance, low luminous efficiency, and was not energy-saving. Later, energy-saving lamps appeared. Although they are more energy-saving and have higher illuminance, they are not environmentally friendly due to the large amount of mercury used. At present, more energy-saving and environmentally friendly LED light sources have emerged. LED light sources have many advantages such as high luminous efficiency, energy saving and long life, and their applications are becoming more and more extensive.

LED screw lamps are widely used in home lighting, shopping mall lighting, etc. In order to meet the illumination requirements, LED screw lamps on the market generally use multiple LEDs on one lamp, which leads to poor heat dissipation and reduces the life of LEDs. , so the existing LED screw lamp cannot install more LEDs to meet the three-dimensional requirements.

The bottom of the fluorescent tube is an aluminum heat dissipation base. The light source substrate is fixed in the flat H-shaped groove of the aluminum heat dissipation base through self-tapping screws. The PC lampshade and the aluminum heat dissipation base pass through the PC lampshade. The tab and the card slot on the aluminum heat dissipation base are fixed together, the LED light source sheet is welded on the light source substrate, the semi-arc surface of the aluminum heat dissipation base is provided with heat dissipation fins, and there is an H-shaped groove in the middle, and the arc of the PC lampshade There are stripes inside, the lower plane of the upper plastic part has six circular grooves evenly arranged around the center, and one circular groove in the center, and the upper plane of the middle plastic part has six circular grooves evenly arranged around the center. There is a circular groove in the center, and three grooves arranged around the center on the lower plane. The bottom surface of the groove is at an angle of 20° to the plane of the plastic part. There are three semicircular grooves arranged around the center, and the bottom surface of the grooves forms an angle of 20° with the plane of the plastic part.

The beneficial effects achieved by the technical solution provided by the utility model are: each fluorescent tube of the utility model is equipped with an independent aluminum heat dissipation base, and an H-shaped groove is arranged in the middle of the aluminum heat dissipation base, so that the heat dissipation area of the aluminum heat dissipation base is large, The heat dissipation is independent of each other and does not affect each other. The overall structure has good heat dissipation and ventilation effects, and the light source has a long life. The fluorescent tubes are arranged in two layers, and the three fluorescent tubes in the lower layer are arranged at a certain angle, so that the LED screw lamp can achieve three-dimensional lighting. The inner wall of the arc of the PC lampshade is striped, which is conducive to the uniform diffusion of light and avoids the appearance of glare.
