Description
Technical field
The invention belongs to LED car lamp technical field, in particular to a kind of LED illuminator of direct current 110V inputs.
Background technology
Continuous development and maturation with LED manufacture technology, and the progressively decline of production cost, LED light source have been opened
Beginning is widely used in the fields such as auto lamp, special lighting light fixture, public illumination, has huge development potentiality, it is considered to be 21
Century light source most with prospects.
The safety component essential as running car, effect of the automobile lamp in terms of automobile active safety to close weight
Will.LED is highly reliable, service life is long, excitation is high, fast response time, small volume are easy to design, brings Zhuo to automobile appearance
The advantages that more changing, it is set to obtain more and more common application in terms of illumination outside car.Into 21st century, LED car lamp is
Through the new lover as automobile trend, it is widely used on the signal lamps such as steering indicating light, Brake lamp.In addition in recent years, people couple
The cry more and more higher of automobile environment-protection energy-conservation, and the extensive concern of people is also result in the advantages of LED energy-conserving and environment-protective, this is LED
Application on automobile lamp provides great space.
LED car lamp on the market is mostly that direct current 12V or 24V drive at present.Direct current 110V inputs involved in the present invention
LED illuminator be applied to subway lamp on, driving voltage is direct current 110V.
The content of the invention
The present invention is directed to the applicable cases of the LED illuminator of direct current 110V inputs, devises one kind and is applied on subway lamp,
Driving voltage is direct current 110V LED illuminator.
The technical solution adopted by the present invention is as follows：The LED illuminator of direct current 110V inputs, including protection module, driving mould
Block, LED module, it is characterised in that the LED illuminator of described direct current 110V inputs is carried out dual using TVS pipe and CBB electric capacity
Protection；Using linear constant current chip controls LED current；Using high-voltage LED, LED4 3 tunnels of series connection are in parallel.Using the big work(of 5000W
Rate TVS pipe and CBB electric capacity suppress transient voltage and filtering, and duplicate protection is played to device.Using LM317 linear constant current chip controls
LED current processed.Using the high-voltage LED of 22V forward voltages, LED4 3 tunnels of series connection are in parallel.
The beneficial effects of the invention are as follows：Add the protection elements such as TVS pipe by using linear constant current chip and in input
It is set to be more easy to test by EMC.By using the high-voltage LED of 22V forward voltages, LED4 3 tunnels of series connection are in parallel, per paths of LEDs just
It is 88V to voltage sum, direct current 110V meets LM317 input and output voltage differences -0.3V~40V requirement when inputting, make linear
Constant current chip can be with normal use, i.e., whole lamp can be used on direct current 110V driving voltages, while high-voltage LED driving current is low,
Effectively reduce chip power-consumption.
Brief description of the drawings
Fig. 1 is the LED illuminator circuit theory diagrams of direct current 110V of the present invention inputs；
Fig. 2 is the LED illuminator PCB top-layer design figures of direct current 110V of the present invention inputs；
Fig. 3 is the LED illuminator PCB bottom-layer design figures of direct current 110V of the present invention inputs.
Embodiment
The embodiment of the present invention is illustrated from circuit theory and PCB design below in conjunction with the accompanying drawings.
The schematic diagram of the present invention is as shown in Figure 1：The rectification that diode D1 is used for circuit is played due to maloperation and made simultaneously
Into both positive and negative polarity reversal connection after protective effect.Two-way TVS pipe D0, CBB electric capacity C1 and patch capacitor C2, C3 be used for surge protection and
Filtering.Linear constant current chip U1, resistance R1, R2, R3 and diode D4 are current constant control parts, and LED electricity is flowed through for setting
Flow and be allowed to constant, wherein make sample resistance after R1, R2, R3 parallel connection.LED1-LED12, resistance R4-R15 and diode D2, D3
It is LED section, LED4 3 tunnels of series connection are in parallel, and D2, D3 are used for rectification and anti-reverse while increase LED module forward voltage, resistance
R4-R15 is equally used for increasing LED module forward voltage, poor to reduce linear constant current chip input and output voltage, so as to reduce core
Piece power consumption.
As shown in Figures 2 and 3, wiring board uses two-sided fabric swatch to the PCB design of the present invention, and LED is all being arranged in PCB just
Face, protection module and drive module are all arranged in the PCB back sides, ensure whole lamp assembling demand, while facilitate the later stage to test and tie up
Repair analysis.
