Embodiment 1

[0016] In Embodiment 1, a movable cover 24 is additionally provided outside the air outlet 28, and its function is to maintain the airtightness of the lamp cap and prevent dust or insects from entering it. The movable cover 24 is only opened outwards when cooling air flows in from the air inlet 27, and when the internal and external air pressure of the lamp cap 20 reaches balance, the movable cover 24 is closed. It is also possible to use a filter screen or the like to replace the movable cover 24, or to use a combination of the movable cover and the filter screen, as long as the purpose of isolating the above-mentioned impurities can be achieved.

[0017] also, figure 1 Although the cross-section of the shown lamp housing 21 is rectangular, the lamp housing can have other various shapes, such as streamlined arc, circular arc, etc.; the transparent cover 22 can be composed of one or more pieces; the number of LED lamps is can be determined as needed, in figure 1 3 lamps ar...

Embodiment 2

[0023] Embodiment three

[0024] like image 3 As shown, in this embodiment, the LED street lamp structure of the present invention includes three parts: a hollow pole 10 , a lamp holder 20 and a control unit 30 . Lamp holder 20 basically includes lamp housing 21, LED lighting assembly 25, light-transmitting cover 22, heat sink 23, air inlet 27, air outlet 28 and movable cover 24; control unit 30 basically includes air inlet 32, air outlet 35 , fan 33, power board 34, air filter 37, gas flow sensor 36 and controller 31.

Embodiment 3

[0026] In the control unit 30, a power board 34 is responsible for power supply. The air filter 37 is installed outside or inside the air inlet 32 ​​, and its function is to prevent dust or particles in the air from contaminating the environment around the LED lighting assembly 25 . The controller 31 is used to control the rotation speed of the fan 33 based on a set value, thereby adjusting the gas flow in the LED street lamp structure. In addition, for example, a temperature sensor 29 can be considered in the lamp cap 20, and the controller 31 can adjust the speed of the fan 33 based on the temperature measured by the temperature sensor 29, so that the temperature inside the lamp cap 20 can be maintained at about A set value can avoid overheating and waste energy.

[0027] The number and installation position of fan 33 can be determined as required, for example, a fan can be installed near the air inlet 32, and another fan can be installed near the air inlet 27 to strengthen...

Abstract

The invention discloses a light-emitting diode (LED) street lamp structure, an LED lamp cap and a cooling method of an LED lamp. The LED street lamp structure comprises a lamp cap, a control unit, a hollow electric pole and a fan, wherein the lamp cap comprises a lamp shell, an LED light-emitting element, a transparent cover, a cooling fin, a second gas inlet, a second gas outlet, a movable coverand / or a filter screen; the lamp shell and the transparent cover form a space for accommodating the LED light-emitting element and the cooling fin; the movable cover and / or the filter screen is arranged on the outer side of the second gas outlet; the control unit comprises a first gas inlet, a first gas outlet, a gas filter and a controller; the gas filter is arranged on the inner side or the outer side of the first gas inlet; the controller is used for controlling the gas flow in the LED street lamp structure; two ends of the hollow electric pole are connected with the first gas inlet and the second gas inlet respectively to form a gas passage between the lamp cap and the control unit; and the fan is arranged in the control unit and / or the lamp cap and rotates to generate gas flow. The LED street lamp structure, the LED lamp cap and the cooling method of the LED lamp are helpful for prolonging the service life of the LED lamp to further save the cost and resources.

Description

technical field [0001] The invention relates to a sealed LED street lamp structure, in particular to an improved sealed LED street lamp structure which can dissipate heat by means of forced convection and can prevent dust and insects. Background technique [0002] Traditional street lamps use bulbs or mercury lamps as light-emitting components, so there are problems of serious energy consumption and short service life; in order to improve the above problems of traditional street lights, street lights using LEDs as light-emitting components have been developed. [0003] Using LED lights with low power consumption, high lighting brightness and long life to replace traditional light bulbs or mercury lamps can effectively solve the above problems, but if the internal temperature of the lamps rises due to poor heat dissipation, high-power LED chips may occur. Light attenuation shortens its service life or the lamp may be damaged as a result. Therefore, "heat dissipation" is a m...
