Embodiment Construction
[0025] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0026] Such as figure 1 , 2 As shown, the present invention includes a heat dissipation base 1 and an LED packaging substrate 2 disposed on the heat dissipation base 1. The heat dissipation base 1 is a columnar structure with a through air flow channel 3 in the middle, and a plurality of On the light source fixing surface, an LED packaging substrate 2 is arranged on the light source fixing surface; LED chips are arranged on the LED packaging substrate 2 . The outer cross-section of the heat dissipation base 1 is a polygonal structure, wherein at least three side planes are provided with light source fixing surfaces. In order to facilitate fixed connection, one end of the heat dissipation base 1 is a fixed end, and a positioning part for fixing is provided on the fixed end. The heat dissipation base 1 is an aluminum extrusion or di...

The invention discloses an LED (light emitting diode) lamp with a hollow radiating base, and relates to an LED lamp. At present, the light emitting angle of the LED lamp is below 150 degrees, generally, in order to change the angle of the emergent light, the final angle of the emergent light of the lamp is changed by adopting a mode of adding a secondary optical lens for an LED, but the final angle of the emergent light is limited, and the light efficiency is lower. The LED lamp with the hollow radiating base comprises the radiating base and LED packaging base plates, and is characterized in that the radiating base is of a columnar structure the middle part of which is provided with a through air channel, the outer side surface of the radiating base is provided with a plurality of light source fixing surfaces, and the light source fixing surfaces is provided with the LED packaging base plates; and the LED packaging base plates are provided with LED chips. The LED lamp with the hollow radiating base has the advantages that the radiating base is provided with the through air channel, materials of the air channel are reduced, the weight is light, the cost is low, the heat radiation is rapid, the lamp is good for large-angle light emission and even 360-degree all-directional light emission, the secondary optical lens is not required, the assembling links are reduced, the cost is lowered, the weight is reduced, and the lighting effect is good.
Description
technical field [0001] The invention relates to an LED lamp. Background technique [0002] At present, traditional LED lamps are made by encapsulating LED chips in metal substrate grooves, and the metal substrate is used as a heat dissipation base, coupled with heat dissipation fins or other heat dissipation devices, a power supply and a suitable lamp shell. Due to the limitation of the LED chip's own luminous angle (the maximum luminous angle is 150 degrees), the luminous angle of the lamps is also below 150 degrees. Usually, in order to change the light output angle, the final light output angle of the lamp is changed by changing the propagation direction of the LED output light by adding a secondary optical lens to the LED. This method can only achieve a maximum luminous angle of 180 degrees, and the light efficiency is low. Contents of the invention [0003] The technical problem to be solved and the technical task proposed by the present invention are to improve and...
