Waterproof LED (Light-Emitting Diode) ball bulb lamp

Abstract

The invention relates to a ball bulb lamp, and particularly relates to a waterproof LED (Light-Emitting Diode) ball bulb lamp. The ball bulb lamp comprises a light-emitting diode pressing plate, a lens, a radiator, a driving power supply and a screwed standard piece, wherein a light-emitting device is arranged in the light-emitting diode pressing plate. The waterproof LED ball bulb lamp is characterized in that a hollow upper cover is arranged at the upper end of the radiator in a closing manner; the hollow position of the upper cover is blocked by the lens; an upper waterproof rubber ring is arranged between the lens and the upper cover; the light-emitting diode pressing plate covers the lower part of the lens; the lens is provided with an on-plate chip, a lower waterproof rubber ring and the radiator which are arranged from top to bottom in sequence and are laminated in a layer-by-layer manner; the lower end of the radiator is closely connected with the lower cover; the lower cover is in sealing connection with the screwed standard piece; and the driving power supply is arranged in the screwed standard piece and is connected with the light-emitting device by an electric wire. The waterproof LED ball bulb lamp has the advantages of uniform heat distribution, reasonable arrangement of a heating device, good radiating effect, good waterproof effect and compact and durable structure.

Description

technical field [0001] The invention relates to a bulb lamp, in particular to a waterproof LED bulb lamp. The utility model belongs to the field of LED lighting equipment, and is especially suitable for lighting fixtures with high calorific value used in humid and watery environments. Background technique [0002] The heat of the LED bulb mainly comes from two parts; one is the heat generated by the LED, and the other is the heat generated by the driving power supply: if the heat from these two parts can be effectively dissipated, it can improve the performance of the LED bulb. service life and cost savings. In a humid and watery environment, if you directly vent to dissipate heat, the moisture in the environment will enter the drive power supply and LED circuit, causing dangers such as short circuit and power failure. Therefore, how to balance heat dissipation and waterproof has become a new problem in the industry. [0003] In the existing technology, there are the foll...

Problems solved by technology

[0013] With this technology, the drive power and LED chips are distributed separately, and the heat dissipation effect is better than other types, and it is sealed and waterproof. However, the distribution of this technology is too compact, and the heat dissipation effect is reduced. The key point is that the LED chip still has not been solved. The problem of uneven heat distribution and local overheating makes the heat dissipation effect limited
