Waterproof LED

Abstract

The invention discloses a waterproof LED, which comprises a whole consisting of a circuit board and a plurality of radiators. At least one light emitting chip is arranged on the circuit board and the radiators, a package portion is arranged on each light emitting chip directly arranged on the corresponding radiator, and a water joint is connected onto the circuit board. Compared with a lamp consisting of common LEDs, the waterproof LED has the advantage that a plurality of thermal resistors are decreased, so that heat can be more rapidly dissipated, the LED is more effectively kept durable and stable, light attenuation is slowed down, and the service life of the LED is prolonged. Moreover, as a light source support, a primary lens and two layers of heat transfer paste or heat transfer pads are omitted, the weight of the whole lamp is lighter. As the LED is waterproof and the light emitting chips are directly fixed onto the radiators, compared with an original LED assembly lamp, the waterproof LED has the advantages that the process of welding the LED on an aluminum substrate is omitted, a waterproof device and reflow welding or manual welding are omitted, equipment investment, material cost and labor cost are reduced, and a pressure-balanced valve and the like are omitted.

Description

technical field [0001] The invention belongs to the field of LED device light sources, and in particular relates to a waterproof LED. Background technique [0002] Existing LEDs have no waterproof function, and waterproof devices are required to form LED lamps, including circuit boards. A light source bracket is arranged above the circuit board, and a light-emitting chip is arranged on the light source bracket. The bottom of the circuit board plays the role of heat dissipation, and then a waterproof device is made on the lamp. The lamp composed of LEDs with this structure has complex structure, limited shape design, general heat dissipation performance, heavy weight and high cost. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, the object of the present invention is to provide a waterproof LED device with simple structure and good heat dissipation effect. [0004] In order to achieve the above-mentioned technical purpose and achi...

Problems solved by technology

[0002] Existing LEDs do not have a waterproof function, and a waterproof device is required to form an LED lamp, including a circuit board. A light source bracket is arranged above the circuit board, and a light-emitting chip is arranged on the light source bracket. The bottom of the circuit board plays the role of heat dissipation, and then make a waterproof device on the lamp. The structure of the lamp composed of LEDs of this structure is complex, the shape design is limited, the heat dissipation performance is average, and the weight is relatively high, and the cost is high.
