Abstract
The utility model relates to an upper end cover of an LED street lamp heat radiator, which comprises an upper end cover base, wherein heat-radiating fins are arranged on the base; and water flowing channels are arranged between adjacent heat-radiating fins. The heat-radiating fins are arranged at the upper end cover part so as to form a whole body with the heat-radiating fins of the heat radiator and be convenient for integral heat radiation of the heat radiator; and the water flowing channels are arranged between adjacent heat-radiating fins, so that dust and dirt deposited in the exposed upper end cover can be conveniently washed away by rainwater when it rains, so that the heat radiator can radiate the heat normally and the safety of the heat radiator can be ensured.
Description
Technical field
The utility model is novel to relate to a kind of LED street lamp, is specifically related to a kind of upper end cover setting of LED street lamp.
Background technology
Along with the lifting significantly of LED power, LED obtains general application as light source at lighting field.Because advantages such as energy consumption is low, long service life, pollution-free, radiationless heat, LED has guided the lighting source revolution of the 4th generation as the representative of typical low-carbon economy industry, becomes the inexorable trend that replaces the traditional lighting light fixture.But because the optoelectronic transformation efficiency of LED lamp is lower, the actual heat that changed into of most of electric energy, if these heats are dissipated as early as possible effectively, it is very obvious that thing followed fuel factor will become, cause junction temperature to rise, reduce the photon of chip outgoing, colour temperature (luminous flux) quality is descended, it is aging to accelerate chip, shortens device lifetime.Therefore most of LED street lamp all adopts the fin-shaped radiator to dispel the heat; deposit dust and dirt through regular meeting in the exposed radiator; the upper end cover of radiator partly is generally the entity end cap; both there be not good heat sinking function; also never taked the measure of dredging accordingly; cause upper end cover partly to deposit dust and dirt can't in time be got rid of, thereby have influence on the normal heat sinking function of radiator, influence the work safety of radiator.
The utility model content
At above the deficiencies in the prior art, it is a kind of at the employed radiator upper end cover of LED street lamp that the utility model provides.
Of the present utility model be achieved through the following technical solutions:
A kind of upper end cover of LED street lamp heat radiator, described upper end cover comprises the upper end cover pedestal, pedestal is provided with fin, is provided with away aquaporin between the described adjacent fin.
Described fin outer rim is curved arch.
The beneficial effects of the utility model are: partly be provided with fin at upper end cover, make the fin of itself and radiator form one, be convenient to radiator and carry out integral heat sink; Establish away aquaporin between adjacent fin, the dust and the dirt that will be deposited in the exposed upper end cover when being convenient to rain fill by rainwater, and radiator can normally be dispelled the heat, and have guaranteed the work safety of radiator.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1 is pedestal; 2 is fin; 3 for walking aquaporin.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further details.The utility model provides a kind of upper end cover of LED street lamp heat radiator, comprises upper end cover pedestal 1, and pedestal is provided with fin 2, is provided with away aquaporin 3 between the adjacent fin 2.
It is the entity setting that the utility model has solved original upper end cover, has both influenced the integral heat sink of radiator, is unfavorable for dust and the dirt eliminating that will deposit in the exposed radiator again.Because the utility model also is provided with fin 2 in upper end cover part, make itself and the fin formation one of radiator, be convenient to radiator and carry out integral heat sink.And between adjacent fin, establish away aquaporin 3 equally, also the passage of leaking water with the radiator part forms path, the dust and the dirt that will be deposited in the exposed radiator when being convenient to rain fill by rainwater, and radiator can normally be dispelled the heat, and have guaranteed the work safety of radiator.
In order to ensure being used with the fin-shaped radiator, the outer rim of the utility model upper end cover generally adopts the curved arch setting.
Claims (2)
1. the upper end cover of a LED street lamp heat radiator is characterized in that described upper end cover comprises the upper end cover pedestal, and pedestal is provided with fin, is provided with away aquaporin between the described adjacent fin.
2. upper end cover according to claim 1 is characterized in that described fin outer rim is curved arch.
