Abstract
The utility model discloses an LED table lamp hollow-out heat dissipation structure which comprises a support fixedly installed on a base, wherein a lamp cap outer shell body is fixedly installed at the upper end of the support, a metal plate is fixedly installed in the lamp cap outer shell body, an LED lamp array is fixedly installed on the lower surface of the metal plate, the upper surface of the lamp cap outer shell body is an arc-shaped face protruding outwards, a plurality of transverse or longitudinal strip-shaped through holes are respectively formed in the upper surface of the lamp cap outer shell body, and a C-shaped heat dissipation channel is formed between the metal plate and the upper surface of the lamp cap outer shell body. The LED table lamp hollow-out heat dissipation structure is simple in structure and reduces cost of materials and enables LED lamps to dissipate heat well through a metal heat radiation mode at the same time, heat of metal heat radiation produces heat convection in the C-shaped heat dissipation channel to enable the temperature in the lamp cap outer shell body to be more uniform, and the local temperature of the LED lamps is stabilized.
Description
Technical field
The utility model relates to LED desk lamp field, specifically is a kind of LED desk lamp hollow out radiator structure.
Background technology
The LED desk lamp is exactly to be that light emitting diode is the desk lamp of light source with LED, and LED is a kind of solid-state semiconductor devices, and it can directly be converted into light to electricity.
Existing LED desk lamp, the temperature inequality of its lamp holder position can be aggravated the life consumption of LED lamp in the lamp holder.
The utility model content
The purpose of this utility model provides a kind of LED desk lamp hollow out radiator structure, the LED lamp is installed on the metallic plate that is fixed in the lamp shell body, upper surface at its lamp shell body arranges a plurality of horizontal or vertical strip through-holes, when reducing material cost, the LED lamp can better be dispelled the heat by the thermal-radiating mode of metal.
The technical solution of the utility model is as follows:
A kind of LED desk lamp hollow out radiator structure, include the support that is fixedly mounted on the base, the upper end of described support is installed with the lamp shell body, it is characterized in that: be installed with metallic plate in the described lamp shell body, the lower surface of described metallic plate is installed with LED lamp array, the upper surface of described lamp shell body is outwards outstanding arcwall face, and the upper surface of lamp shell body is respectively equipped with laterally a plurality of or strip through-hole longitudinally, forms C shape heat dissipation channel between the upper surface of described metallic plate and lamp shell body.
Described LED desk lamp hollow out radiator structure, it is characterized in that: the material of described lamp shell body is plastics.
The beneficial effects of the utility model:
The utility model is simple in structure, the LED lamp is installed on the metallic plate that is fixed in the lamp shell body, upper surface at its lamp shell body arranges a plurality of horizontal or vertical strip through-holes, when reducing material cost, the LED lamp can better be dispelled the heat by the thermal-radiating mode of metal, the thermal-radiating heat of metal produces thermal convection current in C shape heat dissipation channel, make that the temperature in the lamp shell body is more even, stablized the local temperature of LED lamp, heat distributes by a plurality of horizontal or vertical strip through-holes.
