Description

A kind of LED bulkhead lamp capable
Technical field
The utility model relates to a kind of light fixture, particularly a kind of LED bulkhead lamp capable.
Background technology
The LED bulkhead lamp capable of selling in the market, major defect is: light efficiency is low, weak heat-dissipating, short, big electric current constant-current supply poor reliability of life-span.And the high-power constant-current supply light fixture of high pressure low current poor stability, cisco unity malfunction is in the 36V safe voltage.Accomplish the constant-current supply of the 36V safe voltage that the 6A electric current is above, cost is high, and reliability declines to a great extent.These all are to influence the main difficult technical that the LED bulkhead lamp capable can not be promoted on a large scale.
The main radiating mode that adopts is that die casting aluminium radiator, heat pipe add that aluminium radiator, fan add aluminium radiator but the radiator of whole lamp power on more than the 170W; Size is big; Mould is expensive, and the market is actually rare, with regard to present great power LED light efficiency; Reaching 80Lm/W has been very high requirement, substitutes at the LED bulkhead lamp capable power that can effectively substitute 250W, 400W metal halid lamp, high-pressure mercury lamp under this light efficiency to be approximately about 125W, 200W.Heat radiation to this high-power LED lamp requires than higher, expensive, and die casting aluminium is because thermal conductivity factor is low, and for high-power LED heat radiation, the size that needs is also big, and whole lamp weight is heavier.
The utility model content
The goal of the invention of the utility model is to provide a kind of LED bulkhead lamp capable,, weak heat-dissipating low with the bulkhead lamp capable light efficiency that solves prior art, short technical problem of life-span.
The technical scheme that the utility model adopts is following:
A kind of LED bulkhead lamp capable; Comprise electric power system, mine lamp lampshade and the mine lamp lamp plate that is arranged on mine lamp lampshade top; Said mine lamp lamp plate bottom surface is provided with the LED lamp pearl that a plurality of serial or parallel connections are formed, and said LED lamp pearl is connected with power supply circuits, above the mine lamp lamp plate, also is fixed with radiator.
As a kind of preferred version, mine lamp lamp plate bottom surface is provided with at least one LED lamp pearl group, and each lamp pearl group is composed in series by at least one LED lamp pearl, and a plurality of LED lamp pearl group parallel connections back is connected with power supply circuits.
As further preferred version, said power supply circuits comprise at least one constant-current circuit, and every string LED lamp pearl group is by corresponding independently constant-current source circuit power supply.
As a kind of preferred version, each LED lamp pearl is provided with corresponding independently reflector.
As a kind of preferred version, said bulkhead lamp capable also comprises and is arranged on the dismountable mine lamp guard in mine lamp lamp plate top, and it is inner that said radiator is arranged on the mine lamp guard, and mine lamp guard side has a plurality of passages.
The utility model can accomplish that light efficiency height, good heat dissipation, water resistance are good, but the high outside work of reliability, life-span are long, and the whole lamp life-span can reach more than 40000 hours.Light fixture is safe and reliable, works under the 36V safe voltage.Cost is low, and can effectively substitute traditional high energy consumption light fixture, and is practical, and promotional value is high.
Description of drawings
Fig. 1 is the structure chart of the utility model;
Fig. 2 is the overall appearance figure of the utility model;
Fig. 3 is the utility model power supply the principle figure.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further detailed explanation.
As depicted in figs. 1 and 2 is the structure chart of the utility model; The utility model is a kind of LED bulkhead lamp capable; Comprise electric power system, mine lamp lampshade and the mine lamp lamp plate that is arranged on mine lamp lampshade top, mine lamp lamp plate bottom surface is provided with at least one LED lamp pearl group, and each lamp pearl group is composed in series by at least one LED lamp pearl; A plurality of LED lamp pearl group parallel connections back is connected with power supply circuits; LED lamp pearl is adopted Philip high-efficient large power LED lamp pearl, loads the 700MA electric current, and single light that can reach 120Lm/w is imitated, plurality of LEDs lamp pearl is also gone here and there and uses; The highlyest can and go here and there 170 large-power LED light beads, whole light fixture can accomplish that 80LM/W effectively solves the low problem of LED bulkhead lamp capable light efficiency.
Be provided with radiator in mine lamp lamp plate upper fixed; Use high 6060 aluminium alloys heat radiation aluminium of large scale thermal conductivity factor (diameter 350mm is above, fin height more than 60mm) or heat pipe to amplify the radiating mode of heat radiation aluminium; And adopt surperficial anode treatment effectively to increase by 15% heat loss through radiation; Adopt the active heat removal mode, solve the heat radiation integrity problem.
As shown in Figure 3, the power work mode adopts aluminium base circuit board plate to carry the mode that constant-current circuit (each parallelly connected front end adopts the constant current chip) adds constant voltage source and works, and has solved the integrity problem of the constant-current supply of high electric current low-work voltage.And the safety issue of high pressure low current mode.
Present embodiment also adopts each LED of reflector coupling of different angles design, solves the luminous intensity distribution design problem of bulkhead lamp capable under the differing heights situation, reaches effectively to substitute traditional high energy consumption light fixture.
Water proof and dust proof design adopts safety glass or acrylic cover dustproof, and interface adopts silica gel sealing ring to add fluid sealant, and aluminium base circuit board also adopts spray marine glue mode to handle, and solves the light fixture air-tightness.
