Abstract

The utility model relates to a lamp for daily lighting. In the technical scheme, a wire, a switch, a fuse, a transformer, a rectifier bridge, a voltage regulator module, an indicator light, a lamp tube drive module and a lamp tube are connected in sequence in an insulating shell. When the switch is switched off, the indicator light is normally on, and the lamp tube can emit lasting bright light.

Description

Energy-efficient desktop type study lamp

Affiliated technical field

The utility model relates to the desktop lighting field, can avoid traditional desk lamp with low cost low in energy consumption to variety of issue and this technical products of eyesight influence.

Background technology

Be flooded with technology and the light source that fish eyes mixes in low and middle-end learning desk lamp market.Common have products such as LED desk lamp, incandescent lamp, and the former is with low cost and power consumption is little, has won a lot of users and the favor of manufacturer.But because single led light beam can't satisfy visual field illumination, the practicality of a lot of manufacturers a plurality of LED light source is provided.Hardly realize to be exactly that these very little light emitting diodes cause the eyesight in the study to descend.Eyes have been caused permanent injury.Reason is that the optically focused performance of each LED there are differences, and has caused the irregular phenomenon of optically focused, and because big with the background luminance contrast, it is bright to have caused lamp to descend, the situation that the lamp limit is dark excessively.To such an extent as under this lamp, learn just to have a dizzy spell soon.And incandescent lamp is because tungsten filament plays heat causes luminously, at first is that light conversion efficiency is low, and has produced extra thermal source.What secondly incandescent lamp sent is little gold-tinted, is unfavorable for vision health.

Summary of the invention

In order to maximize all adverse factors that solve in the learning process at night, the utility model provides a kind of energy-efficient desktop type study lamp.The not only energy-efficient and spectroscopic pure of this lamp does not have stroboscopic, and lamp tube service life reaches 10000 hours.Comfortable environment in the maximized construction work and study.

The technical scheme that the utility model adopted is: the insulation shell in, civil power through master switch to protective tube, again through protective tube to transformer, transformer is converted to safe alternating voltage with civil power; After through low pressure protective tube branch two-way, whether one the tunnel drives light emitting diode through current-limiting resistance, be used to indicate the output of transformer normal; One the tunnel connects lamp tube drive circuit boosts to the fluorescent tube both sides, and voltage loads on the fluorescent tube both sides, makes the fluorescent tube instant igniting.Light tube electric voltage is through rectifying and voltage-stabilizing, so it is wide not have stroboscopic, luminosity height, illumination range.Owing to adopt widely used voltage type, also can increase battery provides back standby electricity support.

The beneficial effects of the utility model are to have solved problems such as stroboscopic, thermal source, illumination range that other lighting sources bring are little, brightness is low, chromatogram is impure, power consumption is big.The aftermarket of forming utility model is common, inexpensive.Because light conversion efficiency height, brightness are big, heat and energy consumption are low, can be competent at routine work, study illumination fully in the work.

Description of drawings

Below in conjunction with accompanying drawing the utility model is described further.

The specific embodiment

In Fig. 1, power supply to high pressure protective tube [8], arrives transformer [9] from high voltage safety tube [8] from left side plug process master switch [2] again.High voltage safety tube [8] selects for use 220 volt of 1 safety lattice to be used to protect transformer [9].Transformer [9] output AC voltage, the power supply input bridge rectifier part because further part needs pure dc source.This part is converted to direct current to the alternating voltage of 50HZ.The series connection specification is that 24 volt of 0.5 low pressure protective tube [10] of pacifying is on positive pole behind the direct current.Because this voltage can fluctuate with the fluctuation of civil power, so the utility model carries out voltage stabilizing with power supply from insuring back input Voltage stabilizing module, because the input prime is parallel with 100 microfarad electric capacity, back level is parallel with 10 microfarad electric capacity, has eliminated clutter and pure power supply is provided.Indicator lamp [12] series limiting resistor is connected in parallel in the circuit, plays the effect of indicating circuit operate as normal.Power supply is imported lamp tube driver [14] at last, boosts to light fluorescent tube [15] required voltage and be used to drive fluorescent tube [15].

To press master switch [2] behind the power connection in Fig. 2 example, at this moment indicator lamp [3] lights, and upper end the Lights section sends strong white light.Adjust gooseneck support [4] to proper angle, the study of can devoting oneself to work.

Claims

1. lamp is used in the study of energy-efficient desktop type, it is characterized in that being fixed with switch [2], indicator lamp [3], gooseneck support [4] on the base [1] of desk lamp, and one of horizontal fixed has the light-source system [5] of insulation crust on gooseneck support [4].

2. desk lamp according to claim 1 [1], its characteristic is: light source is CCFL CCFL [14].
