Abstract
A portable LED emergency overhead lamp in vehicles can serve as an emergency lamp convenient for using when the vehicles break down. The beneficial effects of the portable LED emergency overhead lamp are that a strong magnet can be adsorbed directly on part of the vehicle surface, and adhesive stickers can simultaneously be used for convenience; an insulation outer shell is mainly internally provided with a light source plate and a drive control plate, wherein high photosynthetic efficiency LED chips are arranged on the light source plate, with photosynthetic efficiency per watt reaching 1001 m/W, the maximum power of the LED chips being 10 W, and the LED chips amounting to a 35 W energy-saving lamp in luminance; the portable LED emergency overhead lamp can be used simultaneously with original interior decoration lamps in the vehicles, so as to make up for the luminance deficiency of the original interior decoration lamps, and to serve as a mobile light source when the vehicle breaks down at night and during maintenance of the vehicle; and the portable LED emergency overhead lamp is convenient to install and use.
Description
Affiliated technical field
The utility model relates to emergent ceiling light in a portable LED car, especially can be used as the convenient use when vehicle breaks down of emergency luminaire.
Background technology
At present, the vehicle interior roof light that vehicle generally uses mostly is embedded mode, and light source is common osram lamp, and the position is fixed.The advantages such as this kind mode has simple in structure, and the replacing light source is convenient.In case but the car inner circuit system breaks down when driving at night, when during use, light source such as breaks down at the problem, can bring inconvenience to vehicle driver.At some special vehicle, the vehicle of brightness in car and light source stability being had relatively high expectations as mobile control room, caravan, medical vehicle etc., usually drive the high pressure lighting with inverter and meet the demands, this mode power consumption is large, and the reliability of inside lighting circuit for vehicle system also can reduce.
Summary of the invention
In order to make up the deficiency of above fixed ceiling light, the utility model provides emergent ceiling light in a portable LED car, this light fixture can be installed on the positions such as car inner top, boot easily, and when externally power supply is broken down, can rely on the reserve battery power supply of lamp interior, drive a vehicle vehicle when breaking down when night, sustainable lighting some hours.
The technical scheme that its technical problem that solves the utility model adopts is: in light fixture insulation crust bottom, place strong magnets, can directly be adsorbed in the part car body surface, can use adhesive sticker bonding simultaneously, facilitated the use of light fixture.Lamp interior comprises light source board and drives control panel, light source board uses the high light efficiency LED chip, every watt of light efficiency can reach 100lm/W, peak power 10W, be equivalent to the brightness of 35W electricity-saving lamp, drive control panel and comprised LED drive circuit part, external power supply and built-in power change-over circuit, built-in power charging circuit, brightness regulating circuit etc.The PMMA material of high transmission rate is used in the insulation crust light transmission part.Improved to greatest extent the light efficiency of light fixture integral body.
The beneficial effects of the utility model are, can use simultaneously by former interior trim lamp, make up original interior trim lamp luminance shortage, and the mobile light source when Vehicular night fault and vehicle maintenance is easy to install.

1. insulation crust upper covers in figure, 2. Power supply hole, 3. brightness regulation knob, 4. acrylic diffuser, 5. light source substrate, the 6.LED light source 7. drives control panel, 8. rechargeable battery, 9. insulation crust lower cover, 10. magnet, 11. lamp switch/emergency button
The specific embodiment
In Fig. 1, Fig. 2, Fig. 3, Power supply hole 2, brightness regulation knob 3, lamp switch/emergency button 11 are placed on insulation crust upper cover 1 jointly, space 90 degree.Lamp switch 11 is three driving switch, can control respectively the open and close of light fixture, emergent (built-in power power supply) three states, Power supply hole 2 can be light fixture 12V or 24V supplied by AC/DC electricity is provided, when rechargeable battery 8 electric weight are not enough, can play simultaneously the charging effect, brightness regulation knob 3 can be controlled light fixture and carry out 1%～99% linear analogue light modulation, with facilitate different automobile types use in to the different requirements of brightness.
In Fig. 4, Fig. 5, insulation crust upper cover 1 adopts the tight fit mode to be connected with insulation crust lower cover 9,7 minutes front and back of light source substrate 5 and driving control panel are placed in enclosure interior, can facilitate maintenance and the replacing of light fixture, bright dipping partly uses light transmittance can reach 95% acrylic diffuser 4, to improve to greatest extent light efficiency.9 1W high-power LED light sources 6 of welding on light source substrate 5 are fully loaded with exportable 1000lm luminous flux when lighting simultaneously.Insulation crust lower cover 9 bottoms can embed magnet 10, and are adsorbable in the part car body surface in use.
In the circuit theory diagrams of Fig. 6, comprised the LED drive circuit and the circuit control section that drive control panel 7, and the topological structure that drives control panel 7 and brightness light-control knob 3, Power supply hole 2, lamp switch 11, rechargeable battery 8.Drive IC is used the HV9911 cake core, can directly connect adjustable resistance light source is done linearity light adjusting, and circuit has the perfect defencive functions such as open-circuit-protection, short-circuit protection, overload protection, under-voltage protection.Built-in power is the 4.8V nickel-hydrogen chargeable cell, when using the external power supply power supply, battery is in charged state, when using powered battery, at first the booster circuit of controlling by ICMC34063, booster voltage is given drive circuitry to 12V, and 30% of former numerical value is down in lamp power and brightness simultaneously automatically, and do not affect dimming function, to improve light fixture service time.
