Abstract
The utility model discloses a digital camera with a light-emitting diode (LED) flashlight, which comprises a power supply, a flashlight driving circuit and a flashlight connected with the flashlight driving circuit in circuit mode, and the flashlight is the LED flashlight. A traditional xenon flashlight used in the digital camera is replaced with the LED flashlight, energy consumption of the flashlight and covered space of the driving circuit are greatly reduced, service life of the flashlight is prolonged, heat radiation caused by the flashlight is reduced, and environment protection requirements are met.
Description
Technical field
The utility model relates to a kind of LED photoflash lamp digital camera.
Background technology
LED is because of long service life, energy saving; Approved widely as environmental protection cleaning light source; Because application is simple and convenient, use cost is low, therefore in the LCD of hand-held products such as mobile phone, MP3, MP4, PMP, DSC, PDA, GPS, PND, game machine, learning machine, notebook is backlight, be used widely simultaneously; Also be widely used in LED flashlight, the portable illumination of mine lamp, architectural lighting, decorative lighting, Sign Board illumination in addition; And fascia is backlight, in front and back fog lamp, the 3rd stop lamp, indicator, taillight and the domestic lighting.The internal characteristics of LED has determined that it is optimal alternative light sources.
At present, the used photoflash lamp of digital camera is xenon flash lamp, and such photoflash lamp energy consumption is high, does not meet environment protection requirement; And flashlight driving circuit takes up space bigger.
The utility model content
The purpose of the utility model is to provide a kind of LED photoflash lamp digital camera, and its energy consumption is lower, and flashlight driving circuit takes up space less.
For realizing above-mentioned purpose, the technical scheme that the utility model adopts is following:
A kind of LED photoflash lamp digital camera comprises power supply, flashlight driving circuit and the photoflash lamp that is connected with said flashlight driving circuit, and said photoflash lamp is the LED photoflash lamp.
The utility model changes the LED photoflash lamp into through the xenon flash lamp that tradition in the digital camera is used; Greatly reduce photoflash lamp energy consumption and with the taking up room of drive circuit; Prolong the useful life of photoflash lamp, reduced the thermal radiation that photoflash lamp causes, met environment protection requirement.
Description of drawings
Fig. 1 is the structural representation of the LED photoflash lamp digital camera that provides of the utility model embodiment.
Embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing.
Referring to shown in Figure 1, a kind of LED photoflash lamp digital camera comprises power supply 1, flashlight driving circuit 2 and the photoflash lamp 3 that is connected with said flashlight driving circuit, and said photoflash lamp 3 is the LED photoflash lamp.
Said LED photoflash lamp not only can be used as flashlight, realizes the illumination functions of camera, can also be used for video capture, strengthens user experience.
The LED photoflash lamp, promptly LED (light emitting diode) basic structure is an electroluminescent semi-conducting material, places on the leaded shelf, uses epoxy sealing all around then, plays the effect of protection internal core.The LED photoflash lamp is not to come luminously through the inner electronics transition of atom, but through voltage being added in the PN junction two ends of LED, makes energy level of PN junction formation itself, electronics transition and to produce photon luminous on this energy level then.
The LED photoflash lamp is because energy consumption is low, brightness is high, can be used in to be used for illumination and flash of light, light filling on the digital camera.Qualified LED photoflash lamp should reach about 100,000 hours the useful life under rated power.
The LED photoflash lamp mainly contains following characteristics:
1) volume is little: LED is that a very little wafer is encapsulated in epoxy resin the inside basically, thus very little, very light; 2) power consumption is low: the LED power consumption is very low, and in general the LED operating voltage is 2-3.6V.Operating current is 0.02-0.03A.In other words: the electricity that it consumes is no more than 0.1W; 3) long service life: under appropriate electric current and voltage, can reach 100,000 hours the useful life of LED; 4) high brightness, low electric weight: than HID or incandescent lamp thermal radiation still less; 5) environmental protection: LED is made by non-toxic material, and containing mercury unlike fluorescent lamp can pollute, and simultaneously LED also can recycling; 6) sturdy and durable: LED is encapsulated in the epoxy resin the inside completely, and is all firmer than bulb and fluorescent tube, also do not have loosening part in the lamp body, and it is non-damageable that these characteristics make that LED can be described as; 7) controllability is strong: can realize versicolor variation.
Because the above-mentioned inward nature characteristic of LED lamp; Determined the utility model after the xenon flash lamp that uses through tradition in digital camera changes the LED photoflash lamp into; Can reduce greatly photoflash lamp energy consumption and with the taking up room of drive circuit; Prolong the useful life of photoflash lamp, reduce the thermal radiation that photoflash lamp causes.
The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection range of the utility model.
