Description

The Waterproof LED illuminating lamp

Technical field

The utility model relates to the illumination electronic technology, particularly relates to a kind of technology of Waterproof LED illuminating lamp.

Background technology

Present LED illuminating lamp all is welded in many low-power LEDs on one wiring board at interval, then this wiring board is fixedly mounted on heat sink or has on the lamp outer casing of heat dispersion, thereby realize heat radiation; On light fixture, also be provided with the transparent sealing face shield that is used for moistureproof and waterproof.For example the patent No. is the disclosed LED illuminating lamp of Chinese utility model of 200720050776.X, presets LED wafer and control circuit thereof on aluminium base, and is provided with diffuser.

The LED illuminating lamp of said structure is because the shared same radiator of a plurality of low-power LEDs, make heat too concentrated, radiator can't be discharged heat fast, its radiating effect is relatively poor, have a large amount of heats and be sealed in the face shield, thereby influence luminous efficiency and the service life of LED, remove the sealing face shield and then make moist easily, as improving radiating effect, can make the excessive and cost rising of light fixture weight again by further increasing radiator; In addition, its overall structure makes and changes also very inconvenience of LED.

The utility model content

At the defective that exists in the above-mentioned prior art, technical problem to be solved in the utility model provide a kind of perfect heat-dissipating, can be waterproof and dampproof, and production, installation, Waterproof LED illuminating lamp easy to maintenance.

In order to solve the problems of the technologies described above, a kind of Waterproof LED illuminating lamp provided by the utility model, comprise framework, be fixedly installed in the pedestal on the framework, be installed at least two LED luminescence units on the pedestal, it is characterized in that: have between each adjacent LED luminous units at interval, described pedestal is an engraved structure, and the periphery of each LED luminescence unit has at least one place hollow out, form the heat loss through convection passage, described LED luminescence unit comprises radiator, wiring board, circuit connecting parts and be installed on led chip on the wiring board, described wiring board and radiator applying are installed and are fixing, described LED luminescence unit integral waterproofing sealing.

Further, the screen that described pedestal is made up of the grizzly bar of at least one coaxial arrangement, and have between the adjacent grill at interval, at least one LED luminescence unit is installed on the every grizzly bar at interval.

Further, described pedestal is latticed panel, and described latticed panel has at least on the crossbar contact LED luminescence unit is installed.

Further, described LED luminescence unit also comprises the lens of being located at described radiator top, and described lens engage with radiator and form waterproof sealing, and in described wiring board and led chip be contained within.

Further, described radiator is provided with the holding part that is used to place led chip and wiring board.

Further, described pedestal offers a linear grooves at the back side that the LED luminescence unit is installed, the circuit connecting parts of described LED luminescence unit through fillistered joint to power supply.

Further, the circuit connecting parts of described LED luminescence unit is introduced behind the groove with colloid sealing and fixing.

Further, described pedestal is made by metal material.

Further, the LED luminescence unit on the described pedestal is formed square, circular, oval, trapezoidal, hexagon or quincuncial array.

The Waterproof LED illuminating lamp that the utility model provides, because its whole guard shield in the air, and the pedestal that the LED luminescence unit is installed is engraved structure, makes its whole permeable structures that forms, and forms effective heat loss through convection passage with the external world, is beneficial to heat radiation; Secondly, because each LED luminescence unit all has independently wiring board and radiator, each LED luminescence unit surface all can directly contact heat radiation with outside air, not only integral heat sink is resolved into the independent heat radiation of each LED luminescence unit, has also increased cooling surface area; Above-mentioned beneficial effect makes the utility model have better heat dispersion compared to existing technology.In addition because the equal independent waterproof sealing of each LED luminescence unit, therefore can be effectively waterproof and dampproof, and produce, install, safeguard also very convenient.
