Abstract

The utility model discloses an aluminium substrate light-emitting diode (LED) which comprises a printed circuit board (PCB) board, 'L' shape brackets, an aluminium substrate, grooves and chips, wherein the aluminium substrate is arranged on the PCB board, the 'L' shape brackets are symmetrically arranged on two ends of the PCB board and the aluminium substrate, the grooves are arranged on the aluminium substrate, and the chips are arranged on the undersurfaces of interiors of the grooves. Compared with installing procedures of a traditional LED light, the aluminium substrate LED has the advantages of being simple in structure and convenient to install, and greatly saves installing time of the aluminium substrate, improves production efficiency, reduces working intensity of operators and reduces labor power cost.

Description

A kind of aluminium base LED

Technical field

The utility model relates to a kind of LED, particularly relates to a kind of aluminium base LED.

Background technology

LED is a kind of semiconductor that can electric energy be converted into luminous energy, and it adopts electroluminescence, has long, advantage such as light efficiency is high, radiationless and low-power consumption of life-span.LED is that a fritter wafer is encapsulated in the epoxy resin the inside basically, and volume is very little; The LED power consumption is quite low, and the electric light power transfer is near 30%, and the operating voltage of general LED is 2-3.6V, and operating current is 0.02-0.03A, and the electric energy of consumption is no more than 0.1W, and the equal illumination effect is than conventional light source energy-conservation nearly 80%; Led light source is the solid cold light source, does not exist filament light-emitting to be prone to shortcomings such as burning, heat deposition, light decay, under appropriate electric current and voltage, can reach 60,000 to 100,000 hours service life, and is longer more than 10 times than the conventional light source life-span; LED uses the chemiluminescence technology, and caloric value is lower than ordinary luminaire; LED is made by nontoxic material, and containing mercury unlike fluorescent lamp can pollute, and simultaneously LED also can recycling, does not have ultraviolet ray and infrared ray in the spectrum; Both do not had heat, and also do not had radiation, dazzle is little; Cold light source can safe touch, belongs to typical green illumination light source; LED is encapsulated in the epoxy resin the inside fully, and is all firmer than bulb and fluorescent tube, also do not have loosening part in the lamp body, not fragile.

LED and ordinary incandescent lamp, spiral energy-saving lamp and T5 three-color fluorescent lamp are compared, and the result shows that the light efficiency of ordinary incandescent lamp is 12lm/W, and the life-span was less than 2000 hours; The light efficiency of spiral energy-saving lamp is 60lm/W, and the life-span was less than 8000 hours; The T5 fluorescent lamp then is 96lm/W, and the life-span is approximately 10000 hours; Can surpass 150lm/W in theory and diameter is 5 millimeters a white light LEDs light efficiency, the life-span can be greater than 100000 hours.

In view of the intrinsic advantage of LED, be mainly used at present instrument board, sound equipment indicator lamp, the switch of display screen, traffic signal display light source, automotive interior backlight, reading lamp and outside brake lamp, taillight, side lamp and head lamp, as the LCD backlight be applied on electronic watch, mobile phone, beeper, electronic calculator and the POS, the LED Down lamp of household electrical appliances, instrument and meter, communication apparatus, microcomputer and toy, family expenses room lighting, LED Ceiling light, LED fluorescent lamp, LED optical fiber lamp etc.

Yet; The operation principle of LED lamp makes and becomes very outstanding in high-power LED illumination industry heat dissipation problem; Many LED illumination schemes are paid little attention to heat radiation; Or technical merit is limited, so the high-powered LED lamp ubiquity of volume production is nothing like theoretical value actual life at present, cost performance is lower than the awkward situation of conventional lamp.

Summary of the invention

For addressing the above problem, the utility model discloses a kind of aluminium base LED, to install simple and conveniently, perfect heat-dissipating has been practiced thrift human cost.

The disclosed a kind of aluminium base LED of the utility model; Comprise pcb board, " L " shape support, aluminium base, groove and chip; The top of described pcb board is provided with aluminium base; Described " L " shape support is symmetricly set on the two ends of pcb board and aluminium base, and described aluminium base is provided with groove, and described chip is arranged on the inner bottom surface of groove.

A kind of improvement of the disclosed a kind of aluminium base LED of the utility model, described groove are trapezoidal groove.

Another improvement of the disclosed a kind of aluminium base LED of the utility model, described trapezoidal groove are at least four.

The disclosed a kind of aluminium base LED of the utility model; Through " L " shape support that is provided with; Can directly pcb board be fixed with aluminium base and be connected; Solved the conventional aluminum substrate inconvenient problem is installed, the excessive temperature when having avoided the work of conventional aluminum substrate is simultaneously concentrated, and has prolonged the service life of chip in the groove.The utility model is simple in structure, and is easy for installation, and with respect to the installation procedure of traditional LED lamp, the utility model has been practiced thrift the set-up time of aluminium base greatly, has improved production efficiency, has reduced operating personnel's working strength, has reduced human cost.
