Abstract
The utility model discloses an efficient heat-dissipation-type outdoor LED projection lamp which comprises a shell body, a power source driving control unit and an LED light-emitting unit which is electrically connected with the power source driving control unit. The shell body comprises an electric appliance cavity and a light source cavity, wherein a partition plate which enables the electric appliance cavity to be separated from the light source cavity is installed on the shell body, the power source driving control unit is installed in the power source cavity, the LED light-emitting unit is installed in the light source cavity, and a plurality of air convection cavities which are communicated with the exterior are formed between the electric appliance cavity and the light source cavity. The efficient heat-dissipation-type outdoor LED projection lamp avoids mutual baking between the power source driving control unit and the LED light-emitting unit, the two ends of each cavity body are designed in an opening mode, the cavity bodies can conduct air convection, the air convection can rapidly guide out heat generated by an LED and an electric appliance, therefore, the heat dissipation efficiency is greatly improved, the local temperature is greatly reduced, the service life of the lamp is prolonged, the light output of the lamp is improved, and the lamp is simple and reasonable in structure.
Description
Technical field
The utility model relates to the LED technical field of lamps, is a kind of high-efficient heat-dissipating outdoor LED floodlight specifically.
Background technology
At present, the LED outdoor lamp, the grade that waterproof is arranged due to the while light fixture, more than generally must reaching IP55, light fixture also needs to install driving power simultaneously, so just causes LED luminescence unit and power driving control unit to be arranged on simultaneously in an airtight environment, the LED luminescence unit is responsive especially to temperature, temperature is higher, and light output is just lower, and the life-span also can reduce greatly simultaneously.All sizes that often need to increase light fixture in design in the past, to strengthen area of dissipation, but this has with LED light source is small and exquisite and does not conform to.
Afterwards, in the improvement technology, people have two adjacent cavitys by housing design, two adjacent cavitys are spaced from each other with a dividing plate, but two pyrotoxin distances are very near, and the two is still mutual baking, cause amount of localized heat to be difficult to derive fast, thereby cause partial LED and electrical equipment temperature all too high, affect life-span and the light output of product.
Summary of the invention
