Abstract

The utility model relates to an LED illuminating lamp, in particular to an LED lamp cup with high power. The lamp cup consists of a lamp cap, a housing and a radiator, wherein, an LED element is arranged on the inner surface of the radiator, the outer surface of the radiator is provided with a plurality of radiating fins or radiating columns, air is communicated between the radiating fins or the radiating columns, which is favorable for the heat generated by a chip being rapidly radiated in air, thereby ensuring that the temperature rise of the LED chip is kept at a low level, fulfilling the purpose of delaying the light decay process and prolonging the service life of the lamp, and having good social and economical benefits.

Description

A kind of LED cup lamp

Technical field

The utility model relates to lighting device, is specifically related to the LED lighting technical field.

Background technology

The existing LED cup lamp that is popular in the city is high-power LED cup light particularly, the design of many employing enclosed constructions, its radiating fin only is distributed in the side of lamp housing, the back position of LED is encapsulated in the lamp housing, radiating fin generally is not set, and inner air is closed and can not exchanges with outside air, the caloric requirement that such structure makes led chip produce is delivered on the radiating fin of lamp housing side through long thermally conductive pathways, its heat-conductive characteristic and heat dispersion are not good, must cause the led chip temperature rise too high, accelerated the light decay process of chip, chip operation life-span and lamp life are shortened.

Goal of the invention

The purpose of this utility model is exactly will the structural design of LED cup lamp be made improvements, and makes that the heat conduction and heat radiation performance of LED cup lamp is better, reaches the purpose that improves lamp life and then improve its economic results in society.

Summary of the invention

Technical solution of the present utility model is: LED cup lamp is designed to organic three sections continuous parts, it is respectively cap part, Lamp cup housing parts and sink side head part, the LED light-emitting component is mounted on the radiator inner surface, the back side design of this radiator inner surface has some quantity radiating fins or thermal column, the lamp body air outside can from lamp body four sides direction flow through between radiating fin or the thermal column the gap and connect mutually, the required power supply module module of cup lamp is placed in the Lamp cup housing, its two power input lines are connected with lamp holder according to a conventional method, and two output lines are connected with led circuit in addition.Said radiator is made by aluminum material or copper material or other alloy material, also can make by materials such as pottery or glass, but cost performance best surely belong to aluminium matter or aluminum alloy materials.

Technique effect

The heat energy that the structure of this novel cup lamp makes led chip produce is transmitted on radiating fin or the thermal column with shortest path, then be dispersed in the air, because air can connect from lamp body four sides direction, hot-air can exchange with outside air apace, obviously more excellent than the existing enclosed construction heat dispersion that does not connect, add radiating fin and increased the area of dissipation that contacts with air with thermal column, further strengthened heat dispersion again, the enhancing of heat conduction and heat radiation performance, the temperature rise that just means led chip will maintain a lower level, thereby slow down the light decay process and improve the life-span.

Description of drawings

Fig. 1 is the utility model LED cup lamp example structure schematic diagram;

Fig. 2 is the vertical view of radiator among the embodiment.

The specific embodiment

See also accompanying drawing; the utility model LED cup lamp can be divided into three sections parts: cap part 1; Lamp cup housing parts 3 and sink side head part 4; this radiator outer surface design has some quantity radiating fins 5 and thermal column 6; obviously; air can connect at the four sides between radiating fin and thermal column; for the ease of connecting the circuit of a plurality of LED; the inner surface of radiator 4 is pasted with the special printed circuit board (PCB) 7 of punching; LED light-emitting component 8 more than at least one passes on the inner surface that the circuit board punching is mounted on radiator; LED just; negative the two poles of the earth are welded on the circuit of printed circuit board (PCB); the required power drives assembly module 2 of cup lamp is placed in the Lamp cup housing 3; the electricity input line of power module is connected with lamp holder; the electric current output line passes on the duct place in circuit plate on the radiator; the port of radiator can be with sealings such as glass cover or optics of lens parts 9, so that protect the LED element and be beneficial to bright dipping.The LED light-emitting component can be packaged great power LED light emitting diode, also can be directly to be encapsulated on the radiator inner surface by light-emitting diode chip for backlight unit to form.Lighthead assembly is the lamp holder of existing various standard specifications of passing through, and also can be designed to the special lamp holder of non-standard specification.Lamp cup housing 3 can be made an available metal or 10 packings of nonmetallic dividing plate between the port of housing and the radiator of materials such as plastics or glass or potteries.
