Description

The tubular LED illuminating lamp that is easy to dispel the heat

Technical field

The utility model relates to field of illuminating device, particularly a kind of tubular LED illuminating lamp that is easy to dispel the heat, and its structure is beneficial to the heat radiation of led light source, and can improve the uniformity of illuminating lamp bright dipping.

Background technology

The LED illuminating lamp promptly uses the illuminating lamp of LED as light source, led light source is compared with gas-discharge lamp with conventional incandescent, have that long service life, start-up time are short, energy-saving effect significantly, do not have ultra-violet radiation and many advantages such as environmental pollution, security height, become generally acknowledged light source of new generation, wide application prospect is arranged.But meanwhile, because led light source is different from the structure and the principle of incandescent lamp and gas-discharge lamp, also Design of Luminaires has been proposed more new demand, wherein, heat dissipation problem is exactly to influence the critical problem that led light source is applied.In the actual electric light transfer process of LED, have only the electric energy about 25% to be converted into luminous energy, remaining most of electric energy still has been converted into heat energy, if this part heat can not in time conduct, not only can have influence on the stable of LED fluorescent material, and along with the warm rising of joint, the life-span of wafer also will be the index downward trend, the performance of grievous injury led light source, so, do not have in the LED luminous efficiency under the reality of breakthrough raising, satisfy the emphasis that requirement that led light source uses just becomes Design of Luminaires by radiator structure, generally, the heat sink of heater members with a high thermal conductivity coefficient combined, the heat that lamp interior is produced by heat sink is drawn out to the outside in heat conducting mode and distributes, this scenario-frame is simple, can satisfy the general LED application scheme of caloric value, but adopt for the highlighted LED illuminating lamp that high packaging density makes for hanging down wattage LED lamp pearl in a large number, just need radiator structure more efficiently, disclose a kind of " lamp that constitutes by LED of band phase change radiator structure " such as Chinese patent literature CN101561129B, include radiator, the lamp pearl, copper base, cooling fluid, seal cover, valve nozzle and installing hole thereof, driving power, utilize the covert and circulation at the night of dispelling the heat to realize the heat radiation of light fixture is cooled off, though this scheme has stronger heat-sinking capability, complex structure, restricted application.

The utility model content

The purpose of this utility model is to provide a kind of tubular LED illuminating lamp that is easy to dispel the heat, not only can realize good heat dispersion, have better outgoing light homogeneity by easy radiator structure, and simple in structure, with low cost, be particularly useful for the highlighted LED illuminating lamp that integrated a large amount of low wattage LED lamp pearl is made.

The utility model adopts following scheme to realize: the high packaging density LED illuminating lamp that adopts simple and easy radiator structure, include led light source, the light source fixing body, radiator, driving power, led light source is installed in the installed surface of light source fixing body, radiator is installed in the radiating surface of light source fixing body, led light source is electrically connected with driving power, be formed with vertically multi-level installed surface on the light source fixing body, the height difference of each mounting layer distance L ED illuminating lamp exiting surface of multi-level installed surface, led light source is distributed in each mounting layer of multi-level installed surface, described illuminating lamp also includes the leaded light post, the light source fixing body adopts tubular structure, be wrapped in leaded light post border, led light source is installed in the multi-level installed surface of light source fixing body inboard, form at least two led light source rings, the radiator that the periphery is surrounded with some heat radiating fins is the hollow cylinder structure, closely is socketed on the radiating surface of light source fixing body.

Further technical scheme is: be formed with the reflective surface of conical hollow in the described leaded light post, the vertex of a cone points to the exiting surface of LED illuminating lamp.

Further technical scheme is: the led light source dislocation on the described multi-level installed surface is arranged.

The utility model is owing to adopted multi-level installed surface, make light fixture under the certain prerequisite of lighting area, can have bigger led light source quantity, and broken away from restriction to led light source shape and spacing, can allow and keep rational heat-dissipating distance between the led light source, thereby adopt conventional radiator structure such as easy high thermal conductivity coefficient heat sink just can satisfy the requirement of dispelling the heat, simultaneously, luminous intensity distribution needs according to light fixture, utilize the distributed in three dimensions characteristic of light source position, can better improve outgoing light homogeneity, have good heat dissipation effect, simple in structure, advantage with low cost is particularly suitable for the highlighted LED illuminating lamp that utilizes a large amount of low wattage LED lamp pearls to make.

Below in conjunction with drawings and Examples the utility model is further elaborated, protection domain of the present utility model includes but not limited to accompanying drawing and the disclosed content of embodiment.

Description of drawings

Fig. 1 is the sectional structure schematic diagram of an embodiment of the utility model.

The specific embodiment

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

As shown in Figure 1, this LED illuminating lamp removes and comprises led light source 1, light source fixing body 5, radiator 8, outside the driving power, also contain a leaded light post 13, be formed with the reflective surface 9 of taper in the middle of this leaded light post 13, the vertex of a cone points to the exiting surface of LED illuminating lamp, the top of leaded light post also is equipped with a ground glass sheet 14, it also is the exiting surface of LED illuminating lamp, light source fixing body 5 is made of an aluminium base that is rolled into tubular, its medial surface promptly constitutes the multi-level installed surface on the light source fixing body 5, being installed on this aluminium base tube medial surface that five-element LED lamp pearl dislocation arranges arranged, the lamp pearl of adjacent two row is vertically staggered, light source fixing body 5 closely is wrapped in the border of leaded light post 13, form five led light source rings that vertically are arranged in leaded light post 13 borders, lay respectively at apart from the different height of exiting surface, radiator 8 also adopts the hollow cylinder structure, the open tubular column internal diameter is consistent with the external diameter of light source fixing body 5, can fit tightly and be socketed on the light source fixing body 5, number of plate-shaped heat radiating fin 11 is looped around the lateral wall of radiator 8, adopt the LED illuminating lamp of this routine structure, by the leaded light post 13 that has the reflective surface 9 that strengthens light guide effect change light to, better broken through the spacing restriction of led light source, can realize the integrated of more led light source, and the also easier realization of multi-level installed surface structure of light source fixing body 5, has good heat dissipation effect, simple in structure, advantage with low cost is more suitable in the ultra-high brightness LED illuminating lamp that utilizes a large amount of low wattage LED lamp pearls to make.
