Abstract

The utility model relates to a high power LED lamp for tunnel illumination, which comprises a basal plate with good heat-conducting property, and a plurality of blue chips and yellow fluorescent substances which are fixed on the basal plate and has the electric connection mode of concatenation or shunt connection, wherein the front part of the basal plate is provided with a front lens, radiators which are also used as a lamp cover are placed on the back part and both sides of the basal plate, and the basal part of the radiator is provided with a driving circuit board. The utility model has the essential points that a plurality of orange chips or amber white chips are arranged among the blue chips, and the drive circuits of the orange chips or the amber white chips form a group by a single electric connection mode. Through changing the current flowing through the group of chips, the light intensity of the chips can be changed. Consequently, the purpose of regulating the color temperature is obtained. The utility model has the characteristic that the requirement of low color temperature is realized by the lamp under the condition that the luminous efficiency is not reduced or luminous efficiency is hardly reduced, and the utility model is particularly suitable for being used in the tunnel.

Description

Tunnel illumination large-power light-emitting diodes lamp
Technical field
The utility model relate to a kind of LED light lamp (hereinafter to be referred as: the LED lamp), especially belong to the large-power light-emitting diodes lamp that a kind of suitable tunnel illumination is used.
Background technology
The tunnel belongs to a kind of many cloud, low-light (level) environment, therefore, places the lighting source in tunnel need have stronger penetration power to cloud.Many at present employing sodium vapor lamps are made light source, and the characteristics of sodium vapor lamp are: colour temperature is between 2000-3000K, and photochromic inclined to one side Huang and mist transmitting are good, are suitable as the tunnel illumination light source.But sodium vapor lamp defective in actual use is: the life-span is short, power consumption is big.Therefore, have now and consider to be used as the tunnel light source with the illuminative high-power LED lamp, but, though this high-powered LED lamp has advantages such as power saving, life-span length, but its colour temperature is between 4000-8000K, and photochromic being not suitable for used in many cloud environment, if colour temperature is accomplished about 3000K, will reduce the luminous efficiency of LED lamp greatly, loss will reach 50%.
Summary of the invention
For overcoming the above-mentioned defective of prior art, the utility model provides a kind of new suitable tunnel illumination large-power light-emitting diodes lamp, this lamp can reach the requirement of low colour temperature not reducing under the few situation of luminous efficiency or luminous efficiency reduction, to use in the suitable tunnel.
For solving the problems of the technologies described above, the utility model has adopted following technical scheme: this tunnel illumination comprises a substrate with good heat conductive performance with the structure of large-power light-emitting diodes lamp, and be fixed on this substrate, electric connection mode is several blue chip and yellow fluorophors thereof of serial or parallel connection, substrate the place ahead is provided with front lens, substrate rear and both sides are equipped with the radiator of double as lampshade, the radiator base portion is provided with drive circuit board, its main points are: be equipped with several orange chips or amber white chip at blue chip chamber, and the drive circuit of orange chip or amber white chip constitutes one group with independent electric connection mode.
During concrete enforcement, being arranged in the orange chip of blue chip chamber or the quantity of amber white chip is the 1/3-1/4 of blue number of chips.
During concrete enforcement, that be compartment setting arranged in a straight line on substrate is white light LEDs and orange light LED (8).
Beneficial effect: illuminative high-power LED lamp in the market adds the YAG fluorophor with blue chip to be made, so the photochromic temperature of sending is higher, if with the fluorophor thickening, though can reduce colour temperature, can lose luminous efficiency simultaneously.The utility model is put into orange optical chip owing to having adopted when adding YAG fluorescent material with blue chip, utilizes two kinds of chips luminous design philosophys that can obtain low color temperature white light simultaneously, inserts orange chip or amber white chip at blue chip chamber; And have the drive circuit of the orange chip that inserted or amber white chip of one's own one group, therefore, change the electric current that flows through this core assembly sheet and just can change its light intensity, thereby reach the purpose of adjusting colour temperature.In addition, because the fluorophor that adds on blue chip also is yellow, so it can not produce very big influence to the luminous efficiency of the orange chip or the amber white chip of insertion.
Description of drawings
Fig. 1 is the main TV structure schematic diagram of an embodiment of the utility model,
Fig. 2 is the main TV structure schematic diagram of another embodiment.
Fig. 3 is the drive circuit schematic diagram.
The specific embodiment
Referring to accompanying drawing.Sequence number is represented respectively among the figure: front lens 1, blue chip 2, orange optical chip 3, substrate 4, lampshade 5, drive circuit board 6, white light LEDs (7), orange light LED (8), constant flow module 9.
Referring to Fig. 1, and in conjunction with Fig. 3.Earlier the led chip of several power-types, by certain geometric arrangements and be fixed on the substrate 4 with good heat conductive performance, for example copper or aluminium base.Present embodiment adopts linear arrangement mode, and blue chip 2 is lined up two row, the middle orange optical chip 3 of row that inserts, and the quantity of orange optical chip 3 (or amber white chip) is the 1/3-1/4 of blue number of chips, the fluorophor of blue chip 2 adopts yellow YAG fluorescent material.Be the convenience of circuit control, the drive circuit of orange chip 3 or amber white chip constitutes one group with independent electric connection mode, and the electric current that changes this core assembly sheet just can change its light intensity (referring to Fig. 3), thereby reaches the purpose of regulating colour temperature.Front lens 1 is established in substrate 4 the place aheads, and substrate 4 rears and both sides are equipped with the radiator 5 of double as lampshade, and radiator 5 base portions are provided with drive circuit board 6.
Fig. 2 is the main TV structure schematic diagram of another embodiment, thereby being intended to illustrate thisly adds method that gold-tinted reduces the mixed light colour temperature and also can make up with the power light-emitting pipe of finished product and constitute, that is: compartment white light LEDs and the orange light LED of being provided with arranged in a straight line on substrate 4.
The LED lamp of this structure can be a line source, also can be area source.
