Abstract

The utility model discloses a novel LED daylight lamp comprising a lamp tube and a substrate arranged in the lamp tube and an LED and an electric resistance arranged on the substrate, also comprising a power supply drive module, the substrate is sealed in the lamp tube, the power supply drive module is positioned outside of the lamp tube, the power supply drive module is detachably connected on two ends of the lamp tube; the power supply drive module is no longer sealed together with the substrate in the lamp tube and is positioned on two ends outside the lamp tube, so that the heat generated when operating can not be reserved in the lamp tube, the heat of the whole LED daylight lamp can be reduced, the service life of the LED is prolonged, when one of the lamp tube and the power supply drive module is damaged, the damaged one can be changed directly, without discarding the whole LED daylight lamp, the material and the expense can be saved, the practicability is reinforced greatly, and the utility model is more environmental-protecting.

Description

Novel LED fluorescent lamp

Technical field

The utility model relates to a kind of lighting, particularly a kind of LED fluorescent lamp.

Background technology

In recent years, the LED fluorescent lamp has obtained development fast, just progressively enters the general lighting field.Compare with traditional incandescent osram lamp and fluorescent lamp, the LED fluorescent lamp has that volume is little, caloric value is low, the advantage that power consumption is little, and can start by the low pressure low current, reaction speed is fast and the energy high frequency time is operated, long service life, thereby the title of " green illumination light source " is arranged.Existing LED fluorescent lamp, a fluorescent tube is all arranged, the electric power driving module that the fluorescent tube inner sealing has substrate and is positioned at the substrate two ends, be welded with a plurality of LED light emitting diodes and resistance on the substrate, the electric power driving module of this LED fluorescent lamp and LED light emitting diode together are enclosed in the fluorescent tube, there is following deficiency in the use: also can produce heat during owing to the electric power driving module operation, make that the caloric value of whole LED fluorescent lamp is high; When any one damaged in electric power driving module and the fluorescent tube, the whole LED fluorescent lamp just must be scrapped and throw away, and causes significant wastage, and environmental-protecting performance is relatively poor, thereby practicality is lower.

The utility model content

The purpose of this utility model provides the Novel LED fluorescent lamp that a kind of caloric value is low, practicality increases.

The technical scheme that its technical problem that solves the utility model adopts is: Novel LED fluorescent lamp, comprise fluorescent tube, be positioned at the substrate of fluorescent tube and be arranged on LED light emitting diode and resistance on the substrate, also comprise electric power driving module, described base plate seals is in fluorescent tube, described electric power driving module is positioned at the outer two ends of fluorescent tube, and is connected with substrate.The dismountable two ends that are connected fluorescent tube of described electric power driving module.

The beneficial effects of the utility model are: electric power driving module no longer is sealed in the fluorescent tube with substrate together, but be positioned at the outer two ends of fluorescent tube, the heat that produces when moving so can not remain in the fluorescent tube, the caloric value of whole LED fluorescent lamp is reduced, the LED life-span is elongated, electric power driving module is positioned at the outer two ends of fluorescent tube, independent mutually with substrate and LED light emitting diode, one of them directly changes electric power driving module and fluorescent tube when breaking down and gets final product, need not to scrap the whole LED fluorescent lamp, save material and expense, practicality strengthens greatly, also environmental protection more.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

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

With reference to shown in Figure 1, Novel LED fluorescent lamp, comprise the fluorescent tube 1 that transparent material is made, be provided with PCB circuit substrate 2 in the fluorescent tube 1 with fluorescent tube length coupling, be fixedly welded with many group LED light emitting diodes 3 and resistance on the one side of substrate 2, the two ends of substrate 2 are connected with electric power driving module 4, and described substrate 2 is sealed in the fluorescent tube 1, described electric power driving module 4 is positioned at outside the fluorescent tube 1, provides power supply by lead-in wire or conductive pin to substrate.Because electric power driving module 4 no longer is to be sealed in together in the fluorescent tube 1 with substrate 2, but be positioned at the two ends of fluorescent tube 1 outside, be installed in the position of the former ballast of fluorescent lamp, except LED and resistance thereof, there is not other any electronic component like this on the substrate 2, in the fluorescent tube 1 except LED no any heat-generating electronic elements except LED and resistance thereof, the heat that produces during electric power driving module 4 operations can not remain in the fluorescent tube, the caloric value of whole LED fluorescent lamp is reduced, the LED life-span is elongated, in addition, two groups of electric power driving modules 4 and fluorescent tube 1 and substrate 2 are independent, can directly change when one of them breaks down, and another one still can keep, need not to scrap the whole LED fluorescent lamp, reduced overlapping investment, saved and to have used, reduce refuse, increased the effect of environmental protection.It is quite convenient when electric power driving module of the present utility model 4 dismountable two ends that are connected fluorescent tube 1, modular structure make dismounting, replacing.

Above-described only is preferred implementation of the present utility model; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the invention design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
